Token usage + model not captured from Cursor hooks

[sketchymedia]

Problem

Real user's Cursor work_blocks all show `tokens = 0` and `model = null`, including after the v1.2.1 token-tracking fix.

Two gaps in `hooks/runtime.js`:

1. `extractTokenUsage(input)` finds nothing for shell/tool hook events (no `usage` in those inputs; `transcript_path` may not be supplied by Cursor). Only `stop`/turn events could plausibly carry usage.
2. `model` / `model_provider` is never extracted or sent at all — the `ai_tool` payload has no model field, so even when tokens exist, cost can't be priced.

Needs before fixing

A captured real Cursor hook payload (esp. for `stop`/turn events) showing where, if anywhere, Cursor exposes token usage and model id. Implementing field-name guesses blind is speculative and risky. Blocked on payload sample.

Impact

Cursor users get no token-cost attribution. Lower priority than #1/#2 but the eventual goal for cost parity with the daemon.

Status after v1.3.0 (which fixed #2/#3):

Token + model capture now does work for the agent-turn path — user rjcrabbe's Cursor blocks since reinstalling show gpt-5.5 with real token counts (input/output/cached). So the v1.2.1 token fix is functioning end-to-end.

What's still missing is capture for non-agent-turn events (plain shell/tool ticks carry no usage), and the original concern that some sessions show model=null. Both need a captured real Cursor stop/turn hook payload to see exactly where usage/model live before coding — keeping this open and blocked on that sample. Lower priority now that the common path works.

Update (2026-06-29): model+token capture works, but the repos have diverged

Model + token capture is implemented and proven working — in the monorepo copy (devclocked-trackers/packages/cursor-plugin/hooks/runtime.js), via the DEV-416 work (resolveModel() from input.model, inferModelProvider()). Live confirmation: user rjcrabbe's Cursor work_blocks now record model = gpt-5.5 with real token counts.

The problem: this standalone repo (Devclocked/cursor-plugin) — where v1.3.0's stream-leak prune + plugin_version stamp shipped — has no model/provider capture at all. So the two cursor-plugin codebases have diverged:

• standalone Devclocked/cursor-plugin: has leak fix + version stamp, missing model capture
• monorepo packages/cursor-plugin: has model capture, status of leak/version-stamp unverified

Blocked on a decision (not code): which repo is the canonical publish source for the marketplace? Once that's settled, port the missing piece across so one repo has both. Holding this open until that's clarified — I can do the port on request.

The original "tokens=0/model=null" symptom is resolved for the common agent-turn path; non-LLM ticks (plain shell/tool) legitimately have no usage.
