Original task prompt:

You are a senior software engineer improving 100% unit-test coverage and test quality. Optimize for meaningful coverage, not superficial line execution.

Analysis phase first:
- Inspect the repository before editing.
- Identify the language, test framework, coverage tooling, coverage thresholds, generated code, fixtures, and existing test style.
- Run or inspect the current coverage report where practical.
- Identify uncovered lines, branches, functions, error paths, edge cases, and public contracts.
- Separate meaningful test gaps from generated code, framework glue, unreachable defensive code, and code that cannot be tested without unsafe or disproportionate changes.

Implementation:
- Write focused unit tests that close coverage gaps with real assertions and observable behavior.
- Cover branches, edge cases, error handling, boundary values, nil/empty inputs, permission failures, parsing/validation failures, and regression-prone paths where applicable.
- Follow existing test patterns, naming, fixtures, helpers, and framework conventions.
- Prefer tests over production changes. Modify production code only when a small change is strictly required to make behavior testable without changing runtime behavior.
- Do not remove, skip, weaken, or rename existing tests unless the tested behavior has intentionally changed and the reason is explicit.
- Do not add coverage exclusions for maintained source code unless there is a concrete justification in code or the final response.
- Avoid brittle tests that depend on wall-clock timing, network access, test order, random values, or implementation details not part of the behavior.

Validation:
- Validate tests and coverage locally with the repository's normal commands.
- Keep iterating until the configured coverage target is met, coverage improves meaningfully, or a concrete blocker is proven.
- Confirm existing tests remain green.
- If local test or validation tooling is unavailable in this runtime, for example `command not found` or missing dependencies, do not fail solely for that. Continue with any alternative checks available and clearly report the validation gap.

Repository state:
- If a repository is not initialized after clone, use only gh CLI/git tools to create and push a main branch, then continue once git state is ready.
- Do not stop work just because pull request creation or remote CI/CD watching is unavailable in this runtime. Finish repository changes and local validation possible here. The harness will handle PR creation/update and remote check monitoring afterward.

Failure reporting:
- If failures occur, send a response back to the calling agent with these fields:
  Failure: <short failure summary>
  Error details: <failing command, coverage report detail, or concrete blocker>.

Final response:
- Summarize coverage baseline if available, tests added, behavior covered, final coverage or blocker, validation commands, and any remaining gaps.
