Improve test coverage in the OpenAI Agents Python repository: run `make coverage`, inspect coverage artifacts, identify low-coverage files, propose high-impact tests, and confirm with the user before writing tests.

Test Coverage Improver

Overview

Use this skill whenever coverage needs assessment or improvement (coverage regressions, failing thresholds, or user requests for stronger tests). It runs the coverage suite, analyzes results, highlights the biggest gaps, and prepares test additions while confirming with the user before changing code.

Quick Start

From the repo root run
```
make coverage
```
to regenerate
```
.coverage
```
data and
```
coverage.xml
```
.
Collect artifacts:
```
.coverage
```
and
```
coverage.xml
```
, plus the console output from
```
coverage report -m
```
for drill-downs.
Summarize coverage: total percentages, lowest files, and uncovered lines/paths.
Draft test ideas per file: scenario, behavior under test, expected outcome, and likely coverage gain.
Ask the user for approval to implement the proposed tests; pause until they agree.
After approval, write the tests in
```
tests/
```
, rerun
```
make coverage
```
, and then run
```
$code-change-verification
```
before marking work complete.

Workflow Details

Run coverage: Execute
```
make coverage
```
at repo root. Avoid watch flags and keep prior coverage artifacts only if comparing trends.
Parse summaries efficiently:
- Prefer the console output from
```
coverage report -m
```
  for file-level totals; fallback to
```
coverage.xml
```
  for tooling or spreadsheets.
- Use
```
uv run coverage html
```
  to generate
```
htmlcov/index.html
```
  if you need an interactive drill-down.
Prioritize targets:
- Public APIs or shared utilities in
```
src/agents/
```
  before examples or docs.
- Files with low statement coverage or newly added code at 0%.
- Recent bug fixes or risky code paths (error handling, retries, timeouts, concurrency).
Design impactful tests:
- Hit uncovered paths: error cases, boundary inputs, optional flags, and cancellation/timeouts.
- Cover combinational logic rather than trivial happy paths.
- Place tests under
```
tests/
```
  and avoid flaky async timing.
Coordinate with the user: Present a numbered, concise list of proposed test additions and expected coverage gains. Ask explicitly before editing code or fixtures.
After implementation: Rerun coverage, report the updated summary, and note any remaining low-coverage areas.

Notes

Keep any added comments or code in English.
Do not create
```
scripts/
```
,
```
references/
```
, or
```
assets/
```
unless needed later.
If coverage artifacts are missing or stale, rerun
```
pnpm test:coverage
```
instead of guessing.
