Coding Plan

Summary

• Introduce k6 load testing from scratch with scripts targeting the exact SLA thresholds specified (p95<500ms, error rate<1%), integrated into CI via GitHub Actions
• Complete security scanning by adding gitleaks, trufflehog, and semgrep to the existing security.yml workflow rather than creating new workflows
• Extend the existing Vitest E2E test suite rather than introducing Playwright/Cypress to avoid framework fragmentation
• Create deployment runbooks and verification scripts that consolidate existing infrastructure knowledge into actionable documentation

Design Choices

Design Choice 1: Load Testing Tool Selection

Options Considered:

1. k6 (JavaScript-based, CLI-first, excellent CI integration, threshold-based pass/fail)
2. Locust (Python-based, UI-driven, better for exploratory testing)
3. Apache JMeter (Java-based, heavyweight, GUI-centric)

Chosen Option: 1

Rationale: k6 — it integrates cleanly with GitHub Actions, supports threshold-based assertions matching the ticket's p50/p95/p99 targets, and produces machine-readable JSON output for CI.

Design Choice 2: E2E Framework Selection

Options Considered:

1. Playwright (new framework, would duplicate existing Vitest setup)
2. Extend existing Vitest E2E suite (leverage what's already working)

Chosen Option: 2

Rationale: Extend existing Vitest E2E suite — the infrastructure already exists in tests/e2e/ with vitest.config.ts, and adding new test files follows the established pattern without introducing framework fragmentation.

💡 User Tips

Implementation Steps

Phase 1: Load Testing Infrastructure

Create the foundational k6 load testing setup with test scenarios targeting the defined SLA thresholds. This phase establishes the tooling that doesn't currently exist in the codebase.

Task 1: Create k6 Load Test Directory Structure

Set up the load testing directory with configuration and utility modules.

• Create tests/load/ directory for all k6 test scripts
• Create tests/load/config.js with base URL configuration (localhost for local, env var for CI)
• Create tests/load/utils.js with shared helpers for authentication headers, request builders, and check assertions
• Add test data file tests/load/test-data.json with realistic video URLs and payload samples

Task 2: Implement Baseline and Normal Load Test Scripts

Create k6 scripts for the 10-user baseline and 50-user normal load scenarios.

• Create tests/load/baseline.js targeting 10 concurrent users with health endpoint warmup
• Create tests/load/normal-load.js with ramping pattern: 30s→10 users, 1m→50 users, 2m hold, 30s rampdown
• Define thresholds matching ticket requirements: http_req_duration['p(50)']<200, http_req_duration['p(95)']<500, http_req_duration['p(99)']<1000, http_req_failed['rate']<0.01
• Test all four specified endpoints: GET /api/v1/health, POST /api/v1/transcript-action, POST /api/v1/process-video, GET /api/v1/cloud-ai/providers/status

Task 3: Implement Peak and Stress Load Test Scripts

Create k6 scripts for the 200-user peak load and 500+ user stress test scenarios.

• Create tests/load/peak-load.js targeting 200 concurrent users with relaxed thresholds: p50<500ms, p95<1s, p99<2s, error rate<5%
• Create tests/load/stress-test.js with ramping pattern to 500+ users to find breaking points
• Stress test should not have pass/fail thresholds — it's exploratory to identify failure modes
• Include think time (sleep) between requests to simulate realistic user behavior

Task 4: Add k6 CI Workflow

Integrate load testing into GitHub Actions for automated regression testing.

• Create .github/workflows/load-tests.yml workflow triggered on workflow_dispatch (manual) and optionally on PRs to main
• Use grafana/k6-action for k6 execution in CI
• Run baseline test first as a gate, then normal load if baseline passes
• Upload JSON results as artifacts for historical tracking
• Add summary comment to PR with pass/fail status and key metrics

🤖 Prompt for AI agents

This phase builds k6 load testing infrastructure from scratch — nothing exists
yet in `tests/load/`, so every file is net-new.

**Directory and shared config (`tests/load/`):**
- Create `config.js` — export a base URL that reads from an environment variable
in CI and falls back to `localhost` for local runs
- Create `utils.js` — export helpers for building authentication headers,
constructing request payloads, and wrapping k6 `check` assertions
- Create `test-data.json` — include realistic YouTube video URLs and request
payload samples used across all scripts

**Baseline and normal load scripts:**
- `baseline.js`: 10 concurrent virtual users, start with a health endpoint
warmup before hitting other endpoints
- `normal-load.js`: ramping executor — 30s ramp to 10 VUs, 1m ramp to 50 VUs,
hold 2m, 30s rampdown
- Both scripts must define k6 `thresholds`: `http_req_duration['p(50)']<200`,
`http_req_duration['p(95)']<500`, `http_req_duration['p(99)']<1000`,
`http_req_failed['rate']<0.01`
- Cover all four endpoints: `GET /api/v1/health`, `POST
/api/v1/transcript-action`, `POST /api/v1/process-video`, `GET
/api/v1/cloud-ai/providers/status`

**Peak and stress scripts:**
- `peak-load.js`: 200 concurrent VUs with relaxed thresholds (p50<500ms, p95<1s,
p99<2s, error rate<5%)
- `stress-test.js`: ramp to 500+ VUs — **no pass/fail thresholds**, purely
exploratory to surface failure modes
- Both scripts must include `sleep()` calls between requests to simulate
realistic think time

**CI workflow (`.github/workflows/load-tests.yml`):**
- Triggers: `workflow_dispatch` (always), optionally on PRs targeting main
- Use `grafana/k6-action` to execute scripts
- Gate: run `baseline.js` first; only proceed to `normal-load.js` if baseline
passes
- Upload JSON output artifacts for historical tracking
- Post a PR comment summarising pass/fail status and key metrics

Phase 2: Security Scanning Completion

Verify existing security scanning works and add missing tools (semgrep, gitleaks, trufflehog) specified in the ticket. The existing security.yml workflow already runs npm-audit, safety, bandit, and trivy, but needs gaps filled.

Task 1: Add Missing Secret Scanning Tools

Implement gitleaks and trufflehog scanning for comprehensive secret detection.

• Add gitleaks job to .github/workflows/security.yml using gitleaks/gitleaks-action
• Configure to scan entire git history (not just current commit) for production launch
• Add .gitleaks.toml configuration to define allowlists for false positives (test fixtures, example configs)
• Document any findings that need immediate remediation

Task 2: Add Semgrep Static Analysis

Add semgrep for pattern-based security analysis beyond what bandit covers.

• Add semgrep job to .github/workflows/security.yml using returntocorp/semgrep-action
• Configure to use p/security-audit and p/python rulesets
• Output SARIF format and upload to GitHub Security tab alongside trivy
• Set to fail on high-severity findings only (avoid blocking on style issues)

Task 3: Create Security Scan Summary Script

Create a script to aggregate and report all security scan results.

• Create scripts/security/aggregate-scan-results.py to parse outputs from all scanners
• Generate unified report showing: critical/high/medium issues by tool, accepted risks with justification
• Add to CI workflow as final step to produce human-readable summary
• Create docs/security/ACCEPTED_RISKS.md template for documenting suppressed vulnerabilities

🤖 Prompt for AI agents

This phase extends the existing `.github/workflows/security.yml` — do not create
a new workflow file. Add jobs alongside the existing npm-audit, safety, bandit,
and trivy steps.

**Secret scanning jobs in `security.yml`:**
- Add a `gitleaks` job using `gitleaks/gitleaks-action` — configure it to scan
the **entire git history**, not just the latest commit
- Create `.gitleaks.toml` at the repo root — define allowlist rules to suppress
known false positives such as test fixtures and example config files
- Document any real findings that require immediate remediation

**Semgrep job in `security.yml`:**
- Add a `semgrep` job using `returntocorp/semgrep-action`
- Enable `p/security-audit` and `p/python` rulesets
- Output results in SARIF format and upload to the GitHub Security tab (same
pattern as the existing trivy SARIF upload)
- Configure the job to fail **only on high-severity findings** — do not block
the pipeline on style-level issues

**Aggregation script and docs:**
- Create `scripts/security/aggregate-scan-results.py` — parse output from all
scanners (gitleaks, trufflehog, semgrep, bandit, trivy) and emit a unified

- Wire this script as the final step in `security.yml` so every run produces a

Phase 3: E2E Test Suite Enhancement

Extend the existing Vitest E2E test suite (tests/e2e/) to cover critical user paths and error scenarios specified in the ticket. The current pipeline.test.ts tests the live deployment but doesn't cover the full workflow depth required.

Task 1: Add Critical Path E2E Tests

Create comprehensive E2E tests for the primary user workflows.

• Create tests/e2e/critical-paths.test.ts with test cases for:
  • Video URL submission → processing initiation → status polling → completion
  • Transcript generation flow via /api/v1/transcript-action
  • Agent dispatch workflow via /api/v1/agents/dispatch → status check
• Use the existing test environment setup from vitest.config.ts (BASE_URL, TEST_YOUTUBE_URL)
• Add timeout handling for long-running video processing (use polling with reasonable timeout)

Task 2: Add Error Scenario E2E Tests

Create E2E tests for error handling and edge cases.

• Create tests/e2e/error-scenarios.test.ts with test cases for:
  • Invalid video URL submission (expect 4xx response with error message)
  • Rate limit handling (rapid requests should receive 429 with Retry-After header)
  • Missing/invalid API key (expect 401/403 responses)
  • Non-existent job ID polling (expect 404)
• Verify error responses include appropriate HTTP status codes and structured error bodies

Task 3: Add E2E Test Documentation

Document the E2E test suite and how to run it locally.

• Update tests/e2e/README.md (create if missing) with test suite overview
• Document environment variables required (BASE_URL, API keys for authenticated endpoints)
• Add instructions for running against local, staging, and production environments
• Document the existing run-and-fix.sh retry mechanism and failure logging

This phase extends the existing Vitest E2E suite in `tests/e2e/` — follow the
patterns already established in `pipeline.test.ts` and `vitest.config.ts`. Do
not introduce Playwright or Cypress.

**Critical path tests (`tests/e2e/critical-paths.test.ts`):**
- Cover three workflows end-to-end:
  1. Video URL submission → processing initiation → status polling → completion
  2. Transcript generation via `POST /api/v1/transcript-action`
3. Agent dispatch via `POST /api/v1/agents/dispatch` followed by a status check
- Read `BASE_URL` and `TEST_YOUTUBE_URL` from the environment, exactly as
`vitest.config.ts` already configures them
- Implement polling with a reasonable timeout for long-running video processing
— do not use a single `await` with a large fixed delay

**Error scenario tests (`tests/e2e/error-scenarios.test.ts`):**
- Cover four failure cases:
  1. Invalid video URL → expect a 4xx response with a structured error body
2. Rapid repeated requests → expect 429 with a `Retry-After` header (backend
rate limit is 60 req/min)
  3. Missing or invalid API key → expect 401 or 403
  4. Polling a non-existent job ID → expect 404
- Assert both the HTTP status code **and** the shape of the error response body
on every case

**Documentation (`tests/e2e/README.md`):**
- Create or update the file with: test suite overview, all required environment
variables (BASE_URL, API key variables), and instructions for running against
local, staging, and production targets
- Document the existing `run-and-fix.sh` retry mechanism and how failure logs
are captured

Phase 4: Pre-Launch Documentation and Verification

Create deployment runbook and verification checklists. Verify all configuration is documented and backup/recovery procedures exist.

Task 1: Create Production Deployment Runbook

Document the step-by-step deployment process with rollback procedures.

• Create docs/deployment/PRODUCTION_RUNBOOK.md consolidating deployment steps from existing scripts
• Document pre-deployment checklist: all CI checks pass, staging verified, secrets configured
• Document deployment steps using existing deploy.yml workflow (tag release, trigger workflow, monitor)
• Document rollback procedure using existing kubectl rollout undo mechanism in deploy.yml
• Include smoke test commands to run post-deployment

Task 2: Create Environment Configuration Documentation

Document all environment variables and external dependencies.

• Create docs/deployment/ENVIRONMENT_VARIABLES.md listing all env vars from backend code
• Categorize by: required for startup, optional features, secrets (managed via Secret Manager)
• Document external service dependencies: YouTube API, Gemini API, Cloud Tasks, etc.
• Reference existing feature flags in config/feature_flags.json and their production settings

Task 3: Verify Backup and Recovery Documentation

Ensure database backup and disaster recovery procedures are documented.

• Review existing Terraform infrastructure (infrastructure/terraform/environments/production/main.tf) for backup configurations
• Document RDS backup settings (30-day retention, multi-AZ already configured)
• Create docs/operations/DISASTER_RECOVERY.md with recovery procedures
• Document data retention policies based on existing S3 lifecycle rules in Terraform

Task 4: Create Pre-Launch Verification Checklist

Create a runnable checklist script for final verification before launch.

• Create scripts/deployment/pre-launch-checklist.py that programmatically verifies:
  • All required environment variables are set (not their values, just presence)
  • Security scan workflows have passed recently
  • Load test results meet SLA thresholds
  • Health endpoints respond correctly
• Output pass/fail status for each check with clear remediation guidance

Research

The project is a FastAPI backend (src/youtube_extension/backend/main.py) with a Next.js frontend, deployed to Kubernetes/Cloud Run. Testing infrastructure uses pytest for Python unit tests (tests/unit/) and Vitest for TypeScript E2E tests (tests/e2e/). CI/CD workflows in .github/workflows/ already include security scanning (security.yml with npm-audit, safety, bandit, trivy) and E2E tests (e2e-tests.yml). Critically, zero load testing infrastructure exists — no k6, Locust, or Artillery configurations anywhere. The backend has rate limiting middleware (60 req/min) and API key authentication on protected endpoints. No conftest.py exists for shared test fixtures.

🚀 Next Steps

🤖 All AI agent prompts combined

Task: 1

This phase builds k6 load testing infrastructure from scratch — nothing exists
yet in `tests/load/`, so every file is net-new.

**Directory and shared config (`tests/load/`):**
- Create `config.js` — export a base URL that reads from an environment variable
in CI and falls back to `localhost` for local runs
- Create `utils.js` — export helpers for building authentication headers,
constructing request payloads, and wrapping k6 `check` assertions
- Create `test-data.json` — include realistic YouTube video URLs and request
payload samples used across all scripts

**Baseline and normal load scripts:**
- `baseline.js`: 10 concurrent virtual users, start with a health endpoint
warmup before hitting other endpoints
- `normal-load.js`: ramping executor — 30s ramp to 10 VUs, 1m ramp to 50 VUs,
hold 2m, 30s rampdown
- Both scripts must define k6 `thresholds`: `http_req_duration['p(50)']<200`,
`http_req_duration['p(95)']<500`, `http_req_duration['p(99)']<1000`,
`http_req_failed['rate']<0.01`
- Cover all four endpoints: `GET /api/v1/health`, `POST
/api/v1/transcript-action`, `POST /api/v1/process-video`, `GET
/api/v1/cloud-ai/providers/status`

**Peak and stress scripts:**
- `peak-load.js`: 200 concurrent VUs with relaxed thresholds (p50<500ms, p95<1s,
p99<2s, error rate<5%)
- `stress-test.js`: ramp to 500+ VUs — **no pass/fail thresholds**, purely
exploratory to surface failure modes
- Both scripts must include `sleep()` calls between requests to simulate
realistic think time

**CI workflow (`.github/workflows/load-tests.yml`):**
- Triggers: `workflow_dispatch` (always), optionally on PRs targeting main
- Use `grafana/k6-action` to execute scripts
- Gate: run `baseline.js` first; only proceed to `normal-load.js` if baseline
passes
- Upload JSON output artifacts for historical tracking
- Post a PR comment summarising pass/fail status and key metrics
===============================================================================

Task: 2

This phase extends the existing `.github/workflows/security.yml` — do not create
a new workflow file. Add jobs alongside the existing npm-audit, safety, bandit,
and trivy steps.

**Secret scanning jobs in `security.yml`:**
- Add a `gitleaks` job using `gitleaks/gitleaks-action` — configure it to scan
the **entire git history**, not just the latest commit
- Create `.gitleaks.toml` at the repo root — define allowlist rules to suppress
known false positives such as test fixtures and example config files
- Document any real findings that require immediate remediation

**Semgrep job in `security.yml`:**
- Add a `semgrep` job using `returntocorp/semgrep-action`
- Enable `p/security-audit` and `p/python` rulesets
- Output results in SARIF format and upload to the GitHub Security tab (same
pattern as the existing trivy SARIF upload)
- Configure the job to fail **only on high-severity findings** — do not block
the pipeline on style-level issues

**Aggregation script and docs:**
- Create `scripts/security/aggregate-scan-results.py` — parse output from all
scanners (gitleaks, trufflehog, semgrep, bandit, trivy) and emit a unified
report grouped by severity (critical/high/medium) per tool
- Wire this script as the final step in `security.yml` so every run produces a
human-readable summary

suppressed vulnerabilities with justification

for the load testing targets, the p50/p95/p99 tiers look reasonable but the stress test at 500+ users needs a warm-up ramp. jumping straight to 500 concurrent users will trigger cold start failures that look like bugs but are actually just infrastructure spin-up. use k6 with a ramping-vus executor that goes from 10 to 500 over 2-3 minutes. for the Playwright E2E portion, run those separately from load tests. mixing functional E2E with load testing in the same pipeline means a slow E2E run blocks your load test results. one non-obvious thing: the video processing endpoint will probably need a much higher timeout than the transcript endpoint, so set per-endpoint thresholds in k6 rather than global ones.

[m13v]

for the E2E testing part of your launch plan, we open sourced a framework that auto-discovers test scenarios by crawling the app and generates Playwright tests with self-healing selectors. the test generation engine: https://github.com/assrt-ai/assrt-freestyle/blob/main/src/core/freestyle.ts - helps get E2E coverage quickly without hand-writing every spec.

Coding Plan

Summary

• Introduce k6 load testing with per-endpoint scoped thresholds (video processing gets 5x higher timeout than health checks) and gradual ramping-vus executor for stress tests
• Complete security scanning by adding gitleaks, trufflehog, and semgrep to the existing security.yml workflow
• Replace hand-written E2E specs with assrt-freestyle auto-discovery and Playwright generation for self-healing browser tests
• Implement automated goal tracking via GitHub Actions that posts PR comments on goal completion and auto-merges/closes when all success criteria are satisfied, enabling self-sustaining execution

Design Choices

Design Choice 1: Load Testing Tool Selection

Options Considered:

1. k6 (JavaScript-based, CLI-first, excellent CI integration, threshold-based pass/fail)
2. Locust (Python-based, UI-driven, better for exploratory testing)
3. Apache JMeter (Java-based, heavyweight, GUI-centric)

Chosen Option: 1

Rationale: k6 — it integrates cleanly with GitHub Actions, supports threshold-based assertions matching the ticket's p50/p95/p99 targets, and produces machine-readable JSON output for CI.

Design Choice 2: E2E Framework Selection

Options Considered:

1. Hand-write Playwright/Cypress specs manually
2. Use assrt-freestyle framework for auto-discovery and test generation

Chosen Option: 2

Rationale: assrt-freestyle — it crawls the application via accessibility tree exploration, generates self-healing Playwright tests with stable selectors, and outputs standard Playwright TypeScript specs that run with npx playwright test. This eliminates brittle hand-written selectors and provides ongoing test maintenance via re-crawling.

Design Choice 3: Goal Tracking Automation Approach

Options Considered:

1. Custom GitHub Action workflow with shell scripts parsing test outputs
2. Dedicated goal-tracking action with structured YAML configuration
3. External service integration (e.g., LinearB, Allstar)

Chosen Option: 1

Rationale: Custom GitHub Action workflow with structured YAML goal configuration — keeps everything in-repo, avoids external dependencies, and allows fine-grained control over what constitutes "goal met" for each phase. The workflow parses test outputs, security scans, and load test results to determine completion status.

Implementation Steps

Phase 1: Load Testing Infrastructure

Create the foundational k6 load testing setup with test scenarios targeting the defined SLA thresholds. This phase establishes the tooling that doesn't currently exist in the codebase.

Task 1: Create k6 Load Test Directory Structure

Set up the load testing directory with configuration and utility modules.

• Create tests/load/ directory for all k6 test scripts
• Create tests/load/config.js with base URL configuration (localhost for local, env var for CI)
• Create tests/load/utils.js with shared helpers for authentication headers, request builders, and check assertions
• Add test data file tests/load/test-data.json with realistic video URLs and payload samples

Task 2: Implement Baseline and Normal Load Test Scripts

Create k6 scripts for the 10-user baseline and 50-user normal load scenarios with per-endpoint thresholds.

• Create tests/load/baseline.js targeting 10 concurrent users with health endpoint warmup
• Create tests/load/normal-load.js with ramping pattern: 30s→10 users, 1m→50 users, 2m hold, 30s rampdown
• Tag each request with endpoint tag (e.g., tags: { endpoint: 'health' }, tags: { endpoint: 'transcript-action' }, tags: { endpoint: 'process-video' }, tags: { endpoint: 'cloud-ai-status' })
• Define per-endpoint scoped thresholds instead of global thresholds:
  • http_req_duration{endpoint:health}: p50<50ms, p95<100ms, p99<200ms
  • http_req_duration{endpoint:transcript-action}: p50<200ms, p95<500ms, p99<1000ms
  • http_req_duration{endpoint:process-video}: p50<1000ms, p95<3000ms, p99<5000ms (video processing is async-initiated, but the POST itself can be slow)
  • http_req_duration{endpoint:cloud-ai-status}: p50<100ms, p95<300ms, p99<500ms
  • http_req_failed{endpoint:health}: rate<0.001, http_req_failed{endpoint:transcript-action}: rate<0.01

Task 3: Implement Peak and Stress Load Test Scripts

Create k6 scripts for the 200-user peak load and 500+ user stress test scenarios with proper ramp-up.

• Create tests/load/peak-load.js targeting 200 concurrent users with per-endpoint thresholds relaxed appropriately:
  • http_req_duration{endpoint:health}: p50<100ms, p95<300ms
  • http_req_duration{endpoint:transcript-action}: p50<500ms, p95<1000ms, p99<2000ms
  • http_req_duration{endpoint:process-video}: p50<2000ms, p95<5000ms (significantly higher for video processing)
  • Error rate<5% across all endpoints
• Create tests/load/stress-test.js using the ramping-vus executor with explicit gradual warm-up stages:
  • Stage 1: 30s ramp from 0 → 10 users (baseline validation)
  • Stage 2: 1m ramp from 10 → 100 users
  • Stage 3: 1m ramp from 100 → 300 users
  • Stage 4: 1m ramp from 300 → 500 users
  • Stage 5: 2m hold at 500 users (steady-state stress)
  • Stage 6: 30s ramp down to 0
• Stress test should not have pass/fail thresholds — it's exploratory to identify breaking points and failure modes
• Include think time (1-3s random sleep) between requests to simulate realistic user behavior

Task 4: Add k6 CI Workflow

Integrate load testing into GitHub Actions as a distinct pipeline stage from E2E tests.

• Create .github/workflows/load-tests.yml workflow triggered on workflow_dispatch (manual) and optionally on PRs to main
• Structure as independent job that does NOT depend on E2E test jobs — load tests measure infrastructure capacity, not functional correctness
• Use grafana/k6-action for k6 execution in CI
• Run baseline test first as a gate, then normal load if baseline passes
• Upload JSON results as artifacts for historical tracking
• Add summary comment to PR with pass/fail status and key metrics (p50, p95, p99, error rate per endpoint)
• Include explicit note in workflow that load tests run in parallel with (not after) E2E tests

- Cover all four endpoints: `GET /api/v1/health`, `POST
/api/v1/transcript-action`, `POST /api/v1/process-video`, `GET
/api/v1/cloud-ai/providers/status`

**Peak and stress scripts:**
- `peak-load.js`: 200 concurrent VUs with relaxed per-endpoint thresholds —
health p95<300ms, transcript p95<1000ms, process-video p95<5000ms, error rate<5%
- `stress-test.js`: use `ramping-vus` executor with explicit 6-stage warm-up
(0→10→100→300→500 users, 2m hold, ramp to 0) — **no pass/fail thresholds**,
purely exploratory
- Both scripts include `sleep()` with 1-3s random think time between requests

**CI workflow (`.github/workflows/load-tests.yml`):**
- Triggers: `workflow_dispatch` (always), optionally on PRs targeting main
- This job is **independent** — it must NOT depend on E2E jobs; load tests run
in parallel
- Use `grafana/k6-action` for execution
- Gate: run `baseline.js` first; only proceed to `normal-load.js` if it passes
- Upload JSON output as artifacts for historical tracking
- Post a PR comment with per-endpoint p50/p95/p99 and error rates

Phase 2: Security Scanning Completion

Verify existing security scanning works and add missing tools (semgrep, gitleaks, trufflehog) specified in the ticket. The existing security.yml workflow already runs npm-audit, safety, bandit, and trivy, but needs gaps filled.

Task 1: Add Missing Secret Scanning Tools

Implement gitleaks and trufflehog scanning for comprehensive secret detection.

• Add gitleaks job to .github/workflows/security.yml using gitleaks/gitleaks-action
• Configure to scan entire git history (not just current commit) for production launch
• Add .gitleaks.toml configuration to define allowlists for false positives (test fixtures, example configs)
• Document any findings that need immediate remediation

Task 2: Add Semgrep Static Analysis

Add semgrep for pattern-based security analysis beyond what bandit covers.

• Add semgrep job to .github/workflows/security.yml using returntocorp/semgrep-action
• Configure to use p/security-audit and p/python rulesets
• Output SARIF format and upload to GitHub Security tab alongside trivy
• Set to fail on high-severity findings only (avoid blocking on style issues)

Task 3: Create Security Scan Summary Script

Create a script to aggregate and report all security scan results.

• Create scripts/security/aggregate-scan-results.py to parse outputs from all scanners
• Generate unified report showing: critical/high/medium issues by tool, accepted risks with justification
• Add to CI workflow as final step to produce human-readable summary
• Create docs/security/ACCEPTED_RISKS.md template for documenting suppressed vulnerabilities

This phase extends the existing `.github/workflows/security.yml` — do NOT create
a new workflow file. Add jobs alongside the existing npm-audit, safety, bandit,
and trivy steps. A missing scanner here is a real security gap before production
launch.

**Secret scanning jobs in `security.yml`:**
- Add a `gitleaks` job using `gitleaks/gitleaks-action` — configure it to scan
the **entire git history**, not just the latest commit
- Create `.gitleaks.toml` at the repo root — define allowlist rules to suppress
known false positives such as test fixtures and example config files
- Document any real findings that require immediate remediation

**Semgrep job in `security.yml`:**
- Add a `semgrep` job using `returntocorp/semgrep-action`
- Enable `p/security-audit` and `p/python` rulesets
- Output results in SARIF format and upload to the GitHub Security tab (same
pattern as the existing trivy SARIF upload)
- Configure the job to fail **only on high-severity findings** — do not block
the pipeline on style-level issues

**Aggregation script and docs:**
- Create `scripts/security/aggregate-scan-results.py` — parse output from all
scanners (gitleaks, trufflehog, semgrep, bandit, trivy) and emit a unified
report grouped by severity (critical/high/medium) per tool
- Wire this script as the final step in `security.yml` so every run produces a
human-readable summary
- Create `docs/security/ACCEPTED_RISKS.md` as a template for recording
suppressed vulnerabilities with justification

Phase 3: E2E Test Suite with assrt-freestyle

Set up assrt-freestyle for automated test discovery and Playwright test generation. This replaces hand-written test specs with auto-generated, self-healing tests based on accessibility tree crawling.

Task 1: Install and Configure assrt-freestyle

Set up the assrt-freestyle framework for application discovery and test generation.

• Install assrt-freestyle dependencies at repo root or in dedicated tools/assrt/ directory
• Create .env.local configuration with required API keys (GEMINI_API_KEY from existing secrets, optional ANTHROPIC_API_KEY)
• Configure target URLs for discovery: local development (http://localhost:3000), staging (https://staging.uvai.io), production (https://uvai.io)
• Install Playwright browsers: npx playwright install chromium
• Create assrt.config.json specifying crawl scope, authentication flows, and excluded paths (admin routes, docs pages)

Task 2: Run Application Discovery and Generate Tests

Execute assrt-freestyle crawl to discover application structure and generate Playwright tests.

• Run discovery crawl against staging environment to map the accessibility tree and navigation flows
• Review generated .assrt/discovery.json output to verify critical paths were discovered:
  • Homepage and template gallery navigation
  • Video URL input and submission flow
  • Pipeline progress display and SSE event handling
  • Dashboard pages and feature pages
• Generate Playwright TypeScript tests from discovery output
• Output tests to tests/e2e/ using .spec.ts naming convention (Vitest uses .test.ts, so no conflict)
• Review generated selectors to ensure they use accessibility-based locators (aria-label, role) rather than brittle CSS classes

Task 3: Configure Playwright for Generated Tests

Set up Playwright configuration to run generated tests alongside existing Vitest HTTP tests.

• Create playwright.config.ts at repo root with:
  • testDir: 'tests/e2e'
  • testMatch: '**/*.spec.ts' (only picks up Playwright files, not Vitest .test.ts files)
  • Projects for chromium, firefox, webkit (start with chromium only for speed)
  • baseURL configurable via env var (default to staging)
  • Reasonable timeouts: 30s per test, 60s for navigation
• Add Playwright dependencies to package.json: @playwright/test
• Create tests/e2e/README.md documenting the dual-framework setup (Vitest for HTTP/API tests, Playwright for browser tests)

Task 4: Add Playwright E2E to CI Workflow

Integrate Playwright tests into CI as a separate job from existing Vitest E2E.

• Update .github/workflows/e2e-tests.yml to add a playwright-e2e job alongside existing Vitest job
• Install Playwright browsers in CI using npx playwright install --with-deps chromium
• Run npx playwright test with HTML report generation
• Upload Playwright HTML report and trace files as artifacts on failure
• Configure to run against staging environment (not production) for PR checks
• Add workflow dispatch option to run against production for smoke testing

Task 5: Document E2E Test Maintenance with assrt-freestyle

Document how to maintain and regenerate tests when the application changes.

• Create docs/testing/E2E_TESTING.md covering:
  • When to re-run discovery (after major UI changes, new features)
  • How to review and accept generated test changes
  • Manual test additions for complex flows not covered by crawling
  • Self-healing selector behavior and how it reduces maintenance burden
• Add npm scripts to package.json: "e2e:discover": "...", "e2e:generate": "...", "e2e:test": "npx playwright test"

This phase introduces assrt-freestyle and Playwright as a second E2E framework
alongside the existing Vitest suite. The `.test.ts` vs `.spec.ts` file naming
convention is what keeps them from colliding — get that wrong and both runners
will fight over the same files, producing false failures that mask real bugs.

**Install and configure assrt-freestyle:**
- Install assrt-freestyle dependencies at repo root or in `tools/assrt/`
- Create `.env.local` with `GEMINI_API_KEY` (pull from existing secrets) and
optional `ANTHROPIC_API_KEY`
- Create `assrt.config.json` specifying crawl scope, auth flows, and excluded
paths (admin routes, docs pages)
- Target URLs: `http://localhost:3000` (local), `https://staging.uvai.io`
(staging), `https://uvai.io` (production)
- Install Playwright browsers: `npx playwright install chromium`

**Discovery and test generation:**
- Run the discovery crawl against staging to map accessibility tree and
navigation flows
- Confirm `.assrt/discovery.json` covers: homepage/template gallery, video URL
input/submission, pipeline progress/SSE events, dashboard and feature pages
- Output generated tests to `tests/e2e/` using `.spec.ts` naming — this is
critical to avoid conflict with Vitest `.test.ts` files
- Verify generated selectors use accessibility-based locators (aria-label, role)
not brittle CSS classes

**Playwright configuration (`playwright.config.ts` at repo root):**
- `testDir: 'tests/e2e'`, `testMatch: '**/*.spec.ts'`
- Start with chromium only for speed; add firefox/webkit projects later
- `baseURL` from env var, defaulting to staging
- Timeouts: 30s per test, 60s for navigation
- Add `@playwright/test` to `package.json`
- Create `tests/e2e/README.md` documenting the dual-framework setup

**CI integration (`.github/workflows/e2e-tests.yml`):**
- Add a `playwright-e2e` job alongside the existing Vitest job — do not replace
it
- Install browsers with `npx playwright install --with-deps chromium`
- Run `npx playwright test` with HTML report output
- Upload HTML report and trace files as artifacts on failure
- PR checks run against staging; add `workflow_dispatch` for production smoke
testing

**Maintenance docs (`docs/testing/E2E_TESTING.md`):**
- Cover: when to re-run discovery, how to review/accept generated test changes,
how to add manual tests for complex flows, and how self-healing selectors reduce
ongoing maintenance
- Add npm scripts to `package.json`: `e2e:discover`, `e2e:generate`, `e2e:test`
(`npx playwright test`)

Phase 4: Pre-Launch Documentation and Verification

Create deployment runbook and verification checklists. Verify all configuration is documented and backup/recovery procedures exist.

Task 1: Create Production Deployment Runbook

Document the step-by-step deployment process with rollback procedures.

• Create docs/deployment/PRODUCTION_RUNBOOK.md consolidating deployment steps from existing scripts
• Document pre-deployment checklist: all CI checks pass, staging verified, secrets configured
• Document deployment steps using existing deploy.yml workflow (tag release, trigger workflow, monitor)
• Document rollback procedure using existing kubectl rollout undo mechanism in deploy.yml
• Include smoke test commands to run post-deployment

Task 2: Create Environment Configuration Documentation

Document all environment variables and external dependencies.

• Create docs/deployment/ENVIRONMENT_VARIABLES.md listing all env vars from backend code
• Categorize by: required for startup, optional features, secrets (managed via Secret Manager)
• Document external service dependencies: YouTube API, Gemini API, Cloud Tasks, etc.
• Reference existing feature flags in config/feature_flags.json and their production settings

Task 3: Verify Backup and Recovery Documentation

Ensure database backup and disaster recovery procedures are documented.

• Review existing Terraform infrastructure (infrastructure/terraform/environments/production/main.tf) for backup configurations
• Document RDS backup settings (30-day retention, multi-AZ already configured)
• Create docs/operations/DISASTER_RECOVERY.md with recovery procedures
• Document data retention policies based on existing S3 lifecycle rules in Terraform

Task 4: Create Pre-Launch Verification Checklist

Create a runnable checklist script for final verification before launch.

• Create scripts/deployment/pre-launch-checklist.py that programmatically verifies:
  • All required environment variables are set (not their values, just presence)
  • Security scan workflows have passed recently
  • Load test results meet SLA thresholds
  • Health endpoints respond correctly
• Output pass/fail status for each check with clear remediation guidance

🤖 Prompt for AI agents

This phase is documentation and tooling — no application logic changes. Every
deliverable is a new file. Gaps here are the ones that cause production
incidents at 2am.

**`docs/deployment/PRODUCTION_RUNBOOK.md`:**
- Consolidate deployment steps from existing scripts and `deploy.yml`
- Sections: pre-deployment checklist (CI green, staging verified, secrets in
Secret Manager), deployment steps (tag release → trigger `deploy.yml` →
monitor), rollback via `kubectl rollout undo` (already present in `deploy.yml`),
and post-deployment smoke test commands

**`docs/deployment/ENVIRONMENT_VARIABLES.md`:**
- Enumerate every environment variable found in the backend source
(`src/youtube_extension/backend/main.py` and related modules)
- Group into three categories: required for startup, optional feature toggles,
and secrets managed via Secret Manager
- List external service dependencies (YouTube API, Gemini API, Cloud Tasks) and
note which env vars control them
- Reference `config/feature_flags.json` and call out recommended production
values

**`docs/operations/DISASTER_RECOVERY.md`:**
- Base recovery procedures on actual Terraform config in
`infrastructure/terraform/environments/production/main.tf`
- Document RDS backup settings (30-day retention, multi-AZ)
- Document data retention policies derived from S3 lifecycle rules in Terraform

**`scripts/deployment/pre-launch-checklist.py`:**
- Programmatically check: presence (not values) of all required env vars, recent
passing status of security scan workflows, load test result artifacts meeting
SLA thresholds (p95<500ms, error rate<1%), and health endpoint liveness
- Every check must emit a clear pass/fail with a concrete remediation message on
failure — no silent failures

Phase 5: Automated Goal Tracking and Self-Sustaining Execution

Implement automated goal tracking that posts PR/issue comments when goals are met and auto-closes/merges when all success criteria are satisfied. This enables self-sustaining execution without manual intervention.

Task 1: Define Goal Configuration Schema

Create a structured configuration file defining all production readiness goals and their success criteria.

• Create .github/goals/production-readiness.yml with structured goal definitions:

  goals:
    load-testing:
      description: "Load tests pass SLA thresholds"
      workflow: load-tests.yml
      success_criteria:
        - artifact: load-test-results.json
          check: "thresholds_passed == true"
    security-scanning:
      description: "All security scans pass"
      workflow: security.yml
      success_criteria:
        - job: bandit
          status: success
        - job: trivy
          status: success
        - job: gitleaks
          status: success
    e2e-tests:
      description: "100% E2E test pass rate"
      workflow: e2e-tests.yml
      success_criteria:
        - job: vitest-e2e
          status: success
        - job: playwright-e2e
          status: success

• Define goals for each ticket success criterion: load test SLAs, security scan pass, E2E 100% pass rate, documentation completeness
• Include auto_merge_on_complete: true flag for enabling auto-merge behavior

Task 2: Create Goal Status Tracking Workflow

Implement a GitHub Action that tracks goal completion across workflow runs.

• Create .github/workflows/goal-tracker.yml triggered by workflow_run events (fires when other workflows complete)
• Parse workflow run results to determine which goals are now satisfied
• Store goal completion status in a structured JSON file committed to a tracking branch (e.g., goal-tracking) or as workflow artifacts
• Use GitHub API to fetch recent workflow run statuses for all goal-related workflows
• Handle edge cases: workflow re-runs should update status, failed runs should reset goal to incomplete

Task 3: Implement Automated PR/Issue Comments

Create the comment automation that posts updates when goals are met.

• Extend goal-tracker.yml to post comments on the associated PR/issue when a goal transitions to "complete"
• Comment format: ✅ **Goal Complete:** [goal name] - [description] with link to successful workflow run
• Post a summary comment showing all goals with checkboxes when the tracker runs:

  ## Production Readiness Progress
  - [x] Load testing passes SLA thresholds (completed 2024-01-15)
  - [x] Security scanning passes (completed 2024-01-15)
  - [ ] E2E tests 100% pass rate (pending)
  - [ ] Documentation reviewed (pending)
  

• Use actions/github-script for GitHub API interactions to post comments
• Deduplicate comments — update existing tracker comment instead of creating new ones (find by unique marker in comment body)

Task 4: Implement Auto-Close and Auto-Merge Logic

Add automation to close issues and merge PRs when all goals are satisfied.

• In goal-tracker.yml, add final step that checks if ALL goals are complete
• If all goals complete and PR exists:
  • Post final comment: 🎉 **All production readiness goals met!** Auto-merging PR.
  • Trigger auto-merge using gh pr merge --auto --squash (requires branch protection to allow)
  • If auto-merge not enabled, post comment requesting manual merge with approval
• If all goals complete and tracking issue exists:
  • Post completion comment with summary of all goals and timestamps
  • Close issue with gh issue close command
• Add safeguard: require explicit auto_close: true in goal config to enable auto-close behavior
• Log all automation actions to workflow summary for audit trail

Task 5: Create Self-Sustaining Execution Documentation

Document how the goal tracking system works and how to extend it.

• Create docs/ci/GOAL_TRACKING.md explaining:
  • How goals are defined in .github/goals/ YAML files
  • How the tracker workflow detects completion
  • How to add new goals for future phases/tickets
  • How auto-merge and auto-close are triggered
  • How to disable automation temporarily (e.g., during incident response)
• Add troubleshooting section for common issues: stuck goals, false positives, comment spam
• Document the self-sustaining model: once configured, the system runs without manual intervention until all goals pass or explicit human override

🤖 Prompt for AI agents

This phase builds a self-sustaining goal tracking system on top of GitHub
Actions — once wired up, it runs without manual intervention. Get the
`workflow_run` trigger and deduplication logic wrong and you'll flood PRs with
duplicate comments or miss goal transitions entirely.

**Goal configuration (`.github/goals/production-readiness.yml`):**
- Define structured YAML with goals for: load-testing (artifact check on
`load-test-results.json` for `thresholds_passed == true`), security-scanning
(job status checks for bandit, trivy, gitleaks), and e2e-tests (job status
checks for vitest-e2e and playwright-e2e)
- Include `auto_merge_on_complete: true` and `auto_close: true` flags as
explicit opt-in safeguards — do not default these to true
- Cover all ticket success criteria: load test SLAs, security scan pass, E2E
100% pass rate, documentation completeness

**Goal tracker workflow (`.github/workflows/goal-tracker.yml`):**
- Trigger on `workflow_run` events so it fires when any of the goal-related
workflows complete
- Use GitHub API (via `actions/github-script`) to fetch recent workflow run
statuses for all goal-related workflows
- Parse results to determine which goals are now satisfied; store completion
state as structured JSON (committed to a `goal-tracking` branch or stored as
workflow artifacts)
- Handle edge cases explicitly: workflow re-runs must update status, failed runs
must reset the goal to incomplete — stale "complete" states are bugs

**PR/Issue comment automation (extend `goal-tracker.yml`):**
- When a goal transitions to complete, post: `✅ **Goal Complete:** [goal name] -
[description]` with a link to the successful run
- On every tracker run, post/update a single summary comment with checkbox
format:
  ```
  ## Production Readiness Progress
  - [x] Load testing passes SLA thresholds (completed YYYY-MM-DD)
  - [ ] E2E tests 100% pass rate (pending)
  ```
- **Deduplicate aggressively**: search for an existing comment with a unique
marker string before posting; update in place rather than creating a new comment
- Use `actions/github-script` for all GitHub API interactions

**Auto-merge and auto-close logic (final step in `goal-tracker.yml`):**
- Only trigger when ALL goals are complete AND the relevant config flag
(`auto_merge_on_complete: true` / `auto_close: true`) is explicitly set
- PR path: post final `🎉 **All production readiness goals met!** Auto-merging
PR.` comment, then run `gh pr merge --auto --squash`; if auto-merge isn't
enabled on the repo, fall back to a comment requesting manual merge
- Issue path: post completion summary with goal names and timestamps, then run
`gh issue close`
- Log every automated action to the workflow summary for a clear audit trail

**Docs (`docs/ci/GOAL_TRACKING.md`):**
- Explain goal YAML schema, how the tracker detects completion, how to add new
goals, how auto-merge/close are triggered, and how to disable automation during
incident response
- Include a troubleshooting section covering: stuck goals, false positives, and
comment spam

Research

The project is a FastAPI backend (src/youtube_extension/backend/main.py) with a Next.js frontend, deployed to Kubernetes/Cloud Run. Testing infrastructure uses pytest for Python unit tests (tests/unit/) and Vitest for TypeScript E2E tests (tests/e2e/). CI/CD workflows in .github/workflows/ already include security scanning (security.yml with npm-audit, safety, bandit, trivy) and E2E tests (e2e-tests.yml). Critically, zero load testing infrastructure exists — no k6, Locust, or Artillery configurations anywhere. The backend has rate limiting middleware (60 req/min) and API key authentication on protected endpoints. Vitest uses *.test.ts pattern while Playwright uses *.spec.ts — these can coexist in tests/e2e/ without conflict.

🤖 All AI agent prompts combined

Task: 1

This phase builds k6 load testing infrastructure from scratch — `tests/load/`
doesn't exist yet, every file is net-new. Missing thresholds or wrong executor
configs will silently pass bad performance regressions into production.

**Directory and shared config (`tests/load/`):**
- Create `config.js` — export a base URL reading from an env var in CI with a
`localhost` fallback for local runs
- Create `utils.js` — export helpers for building authentication headers,
constructing request payloads, and wrapping k6 `check` assertions
- Create `test-data.json` — include realistic YouTube video URLs and request
payload samples used across all scripts

**Baseline and normal load scripts:**
- `baseline.js`: 10 concurrent VUs, warmup against the health endpoint before
hitting other endpoints
- `normal-load.js`: ramping executor — 30s ramp to 10 VUs, 1m ramp to 50 VUs,
hold 2m, 30s rampdown
- Both scripts tag every request with an `endpoint` tag: `tags: { endpoint:
'health' }`, `tags: { endpoint: 'transcript-action' }`, `tags: { endpoint:
'process-video' }`, `tags: { endpoint: 'cloud-ai-status' }`
- Both scripts define **per-endpoint scoped thresholds** — not global ones:
  - `http_req_duration{endpoint:health}`: p50<50ms, p95<100ms, p99<200ms
- `http_req_duration{endpoint:transcript-action}`: p50<200ms, p95<500ms,
p99<1000ms
- `http_req_duration{endpoint:process-video}`: p50<1000ms, p95<3000ms,
p99<5000ms
- `http_req_duration{endpoint:cloud-ai-status}`: p50<100ms, p95<300ms, p99<500ms
- `http_req_failed{endpoint:health}`: rate<0.001;
`http_req_failed{endpoint:transcript-action}`: rate<0.01
- Cover all four endpoints: `GET /api/v1/health`, `POST
/api/v1/transcript-action`, `POST /api/v1/process-video`, `GET
/api/v1/cloud-ai/providers/status`

**Peak and stress scripts:**
- `peak-load.js`: 200 concurrent VUs with relaxed per-endpoint thresholds —
health p95<300ms, transcript p95<1000ms, process-video p95<5000ms, error rate<5%
- `stress-test.js`: use `ramping-vus` executor with explicit 6-stage warm-up
(0→10→100→300→500 users, 2m hold, ramp to 0) — **no pass/fail thresholds**,
purely exploratory
- Both scripts include `sleep()` with 1-3s random think time between requests

**CI workflow (`.github/workflows/load-tests.yml`):**
- Triggers: `workflow_dispatch` (always), optionally on PRs targeting main
- This job is **independent** — it must NOT depend on E2E jobs; load tests run
in parallel
- Use `grafana/k6-action` for execution
- Gate: run `baseline.js` first; only proceed to `normal-load.js` if it passes
- Upload JSON output as artifacts for historical tracking
- Post a PR comment with per-endpoint p50/p95/p99 and error rates
===============================================================================

Task: 2

This phase extends the existing `.github/workflows/security.yml` — do NOT create
a new workflow file. Add jobs alongside the existing npm-audit, safety, bandit,
and trivy steps. A missing scanner here is a real security gap before production
launch.

**Secret scanning jobs in `security.yml`:**
- Add a `gitleaks` job using `gitleaks/gitleaks-action` — configure it to scan
the **entire git history**, not just the latest commit
- Create `.gitleaks.toml` at the repo root — define allowlist rules to suppress
known false positives such as test fixtures and example config files
- Document any real findings that require immediate remediation

**Semgrep job in `security.yml`:**
- Add a `semgrep` job using `returntocorp/semgrep-action`
- Enable `p/security-audit` and `p/python` rulesets
- Output results in SARIF format and upload to the GitHub Security tab (same
pattern as the existing trivy SARIF upload)
- Configure the job to fail **only on high-severity findings** — do not block
the pipeline on style-level issues

**Aggregation script and docs:**
- Create `scripts/security/aggregate-scan-results.py` — parse output from all
scanners (gitleaks, trufflehog, semgrep, bandit, trivy) and emit a unified
report grouped by severity (critical/high/medium) per tool
- Wire this script as the final step in `security.yml` so every run produces a
human-readable summary
- Create `docs/security/ACCEPTED_RISKS.md` as a template for recording
suppressed vulnerabilities with justification

- Install browsers with `npx playwright install --with-deps chromium`
- Run `npx playwright test` with HTML report output
- Upload HTML report and trace files as artifacts on failure
