fix(tools): scope wait integer coercion to the bare wait tool

[lidge-jun]

Summary

Codex Desktop's bare wait tool advertises yield-time_ms and max_tokens as
JSON number while its runtime demands u64, so 120000.0 and 8000.0 come back
rejected. #2316 fixed exactly this shape for timeout_ms and nothing else —
src/lib/tool-argument-integers.ts:77 allowlists a single field name — so the
two wait fields still round-trip unchanged through both bridge paths.

The repair is scoped to the bare wait tool rather than added to the global
allowlist. yield-time_ms and max_tokens are ordinary names: Cursor has its own
yield_time_ms at src/adapters/cursor/tool-definitions.ts:42, and max_tokens
is fair game for any third-party tool that legitimately wants a fraction. A
global entry would silently rewrite all of them.

Closes #2443.

Verification

bun test tests/tool-argument-integers.test.ts
 35 pass, 0 fail, 45 expect() calls
bun run typecheck
 exit 0

Red-green on the new regressions: before the source change the same file ran
33 pass / 2 fail, with bare wait retaining 120000.0 and 8000.0.

The suite also pins the negative cases — fractional 1.5 is preserved, and the
same field names on a different tool and on a namespaced tool stay byte-identical.
tests/tool-argument-integers.test.ts:328 previously asserted the opposite
contract for yield-time_ms; it was written for #2316's narrower scope and is
updated deliberately here rather than dropped.

Checklist

• Targets dev
• Focused regression test added near the existing coverage
• Red-green verified, not assumed
• No request-body, API-key, or account-identifier logging
• Bun-native TypeScript, exports preserved

Summary by CodeRabbit

• Bug Fixes

  • Improved handling of integer-valued tool arguments for the wait tool.
  • Preserved fractional values for unrelated tools and namespaced wait calls.
  • Applied consistent behavior across streaming and non-streaming tool calls.

• Tests

  • Added coverage for supported wait fields and confirmed unrelated tools remain unaffected.

📝 Walkthrough

Walkthrough

The change scopes integral-float repair to the bare wait tool. The coercion logic receives and propagates the tool name. Streaming and buffered bridge paths preserve namespaced tool behavior. Tests cover both paths and fractional values.

Changes

Wait tool integer coercion

Layer / File(s)	Summary
Tool-scoped integer coercion src/lib/tool-argument-integers.ts	The coercion API accepts an optional toolName and propagates it through nested arrays and objects. The bare wait tool permits integral-float repair for yield-time_ms and max_tokens.
Namespace-aware bridge wiring src/bridge.ts	Streaming and buffered tool-call handling passes the tool name for unnamespaced calls and passes undefined for namespaced calls.
Wait tool integration coverage tests/tool-argument-integers.test.ts	Tests verify repairs for bare wait, preservation of fractional values, exclusion of unrelated tools, and exclusion of namespaced cursor_wait calls in both bridge paths.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to bd2c5

The PR narrowly scopes integer coercion to the bare wait tool and includes focused tests and typechecking. A few test fixtures should be aligned with the event type, but no actionable merge-blocking risk remains.

Keep all tool_call_end fixtures within the AdapterEvent contract.

AdapterEvent defines tool_call_end without an id field. Remove id from lines 388, 391, 394, and 397. Apply the same correction to the existing fixtures at lines 154, 174, 187, 347, and 359 if this file is type-checked.
