Codecov

Auth is already in env — dot_bashrc exports CODECOV_API_TOKEN. The codecov-api wrapper in ~/.local/bin/ injects auth + the https://api.codecov.io base. Don't shell out to curl directly.

Triggers

• "Is <test> flaky?" / "What's its failure rate?"
• "Show failed tests on <branch> recently."
• "Why is <test> failing?" (stack trace lookup)
• "What's the coverage delta on this PR / file / branch?"
• Any Codecov UI URL behind the login wall.

Repo coordinates

Most paths take {service}/{owner}/{repo} where service is one of github, gitlab, bitbucket (no .com). Derive from the current checkout via git remote get-url origin.

REST — flaky / failed tests

GET /api/v2/{service}/{owner}/repos/{repo}/test-results/

Verified query parameters:

• branch — filter by branch name
• commit_id — filter by commit SHA
• outcome — pass | failure | skip | error
• duration_min / duration_max — seconds
• page / page_size — pagination

codecov-api "/api/v2/github/<owner>/repos/<repo>/test-results/?branch=main&outcome=failure&page_size=100"

Detail (stack trace, etc.):

codecov-api "/api/v2/github/<owner>/repos/<repo>/test-results/<id>/"

REST has no flake_rate filter and no test-name filter. For a ranked flake answer, paginate outcome=failure, group by name, divide by total runs of that name (separate call without outcome), or use GraphQL.

GraphQL — ranked flake aggregates

POST /graphql/ is the same wrapper:

codecov-api /graphql/ \
  -X POST -H 'Content-Type: application/json' \
  -d '{"query":"...","variables":{...}}'

Schema entry points worth knowing: repository.testAnalytics.testResults, repository.testAnalytics.flakeAggregates. When in doubt, fetch the schema ({ __schema { types { name } } }) and read it.

Coverage queries

The full v2 swagger lives at https://api.codecov.io/api/v2/docs/ — consult it for commits/, report/, pulls/{id}/, compare/ endpoints rather than memorising paths. All take the same {service}/ {owner}/{repo} prefix and the same auth.
