When the best-effort duplicate-name lookup fails, test create currently continues without explaining why the advisory was skipped, even under --debug. This adds a debug-only stderr diagnostic to the shared lookup used by both --code-file and --plan-from.

Refs #186

The change preserves creation and exit behavior, keeps non-debug output byte-identical, and isolates diagnostic-write failures so they cannot prevent creation. It covers only the duplicate-name lookup; the broader issue remains open, and the skill-nudge work completed in #317 is untouched.

Validation:

• 10 new regression cases cover both creation paths, JSON/text output, default and verbose-only silence, successful lookups, and a throwing diagnostic sink. Against the original source, the four diagnostic assertions fail; they pass with this change.
• Build and CLI version smoke check pass.
• ESLint passes with 0 errors (85 existing unused-disable warnings); Prettier and TypeScript checks pass.
• Local end-to-end suite: 101 passed, 1 skipped.
• Full unit/coverage suite (env -u NO_COLOR npm run test:coverage): 3,706 passed, 2 skipped; lines 89.98%, branches 87.98%, functions 92.39% (all above the 80% gate). The host sets NO_COLOR=1, which makes seven existing ANSI ticker tests fail; unsetting it makes all 30 ticker tests and the complete suite pass. No ticker code was changed.

Locally verified on macOS / Node 24.16.0. Linux Node 20/22 and Windows remain for repository CI.

Summary by CodeRabbit

• Documentation
  • Clarified that test creation performs a best-effort lookup for an existing test with the same name for both code-file and plan-based creation. The lookup is skipped during dry runs.
• Bug Fixes
  • Lookup failures no longer prevent test creation. With --debug, skipped lookups and their reasons are reported on stderr; otherwise, they remain silent. Failures while reporting diagnostics also do not interrupt creation.

Walkthrough

The duplicate-name advisory reports lookup failures to stderr only when --debug is enabled. Lookup failures and diagnostic-write errors do not block creation. Both code-file and plan-based creation paths pass the debug setting.

Changes

Duplicate-name advisory

Layer / File(s)	Summary
Debug diagnostics across create paths src/commands/test.ts, src/commands/test.test.ts, DOCUMENTATION.md	The advisory reports lookup failures to stderr in debug mode and swallows errors from diagnostic writes. Both create paths pass the debug setting. Tests cover lookup success and failure, output modes, and diagnostic-write errors. The documentation describes the advisory, including its behavior under --dry-run.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Merge Risk: ⚪ Minimal · up to f826f

Lookup failures remain non-fatal in both creation paths, with diagnostics limited to debug mode. The change is ready to merge after normal checks.
