# <Skill title>

## Target

Which harness, which file, which lines. Cite a permalink to the
relevant code at the audit commit.

## Symptom

What's broken in the user's current setup. Be concrete:

- Which API call is wrong
- What field is missing/wrong/volatile
- What `usage` field comes back zero or wrong

## Fix

```diff
--- a/path/to/file.ts
+++ b/path/to/file.ts
@@
-  old line
+  new line
```

If the fix is multi-step or conditional, list the steps.

## Verify

After applying, the agent should:

1. Run `<command>` to exercise the code path.
2. Capture the wire (mitmproxy or harness debug log).
3. Confirm `<specific assertion>` — e.g.
   `usage.cache_read_input_tokens > 0` on the second turn.

If the assertion fails, the fix didn't land or there's a second
upstream issue. Stop and report.
