coverage-audit

name	coverage-audit
description	Audit a GitHub/GitLab organization's repositories for code coverage status. Generates CSV spreadsheet showing which repos have tests, Codecov integration, and what's missing. Use when user asks to audit an org, create a coverage spreadsheet, or assess coverage gaps across repositories.

Coverage Audit Skill

Scan GitHub/GitLab org → produce CSV with coverage status per repo.

When to Use

• User asks to audit a GitHub/GitLab org for coverage
• User wants a spreadsheet of repos with test/Codecov status
• User needs to identify coverage gaps across an organization

Important: You Execute Everything

The user should NOT write or run scripts manually. YOU (the AI agent) write the audit script, execute it, and present results. The user only provides input (org name, scope) and reviews output.

Important: Ask Before Acting

Never assume. Always confirm. If you are unsure about anything — org name spelling, scope (public vs private), platform (GitHub vs GitLab) — stop and ask the user before proceeding.

Rules:

• Do NOT start the audit without confirming org name and scope
• If the org has many repos (100+), warn user it may take several minutes
• If GitHub/GitLab API rate limit is low, warn user and ask how to proceed
• If results look unexpected (0 repos, all archived), flag it and ask
• Show summary stats after audit completes, ask if user wants to re-run with different parameters

Prerequisites

GitHub

• Token with repo scope (private repos) or public_repo (public only)
• For org-level metadata: read:org scope
• Help the user set GITHUB_TOKEN if needed:

  export GITHUB_TOKEN=$(gh auth token)
  

  Or if they don't have gh CLI, walk them through creating a token at https://github.com/settings/tokens
• GitHub Enterprise: If user provides a GHE URL, use https://<host>/api/v3/ as the API base instead of https://api.github.com/

GitLab

• Token with read_api scope
• Help the user set GITLAB_TOKEN:

  export GITLAB_TOKEN=glpat-xxxxxxxxxxxxxxxxxxxxx
  

  Create at https://gitlab.com/-/user_settings/personal_access_tokens (or equivalent for self-hosted GitLab)
• Self-hosted GitLab: Use https://<host>/api/v4/ as the API base

Instructions

Step 1: Gather Info

Ask user:

1. Org name — GitHub org URL or name (e.g., ansible, konflux-ci), or GitLab group path (e.g., gitlab-org/ci-cd)
2. Scope — public repos only, or include private?
3. Platform — GitHub (default), GitHub Enterprise, GitLab.com, or self-hosted GitLab?
4. Codecov API — do they have a Codecov API token? (optional, enriches results with actual coverage data)

If platform is GitHub Enterprise or self-hosted GitLab, also ask for the instance URL.

Step 2: Write and Run Audit Script

Create a Python script that:

1. Fetches all repos via platform API with pagination

   • GitHub: GET /orgs/{org}/repos?per_page=100&page=N — follow Link header or increment page until empty response
   • GitLab: GET /groups/{group}/projects?per_page=100&page=N&include_subgroups=true — follow X-Next-Page header

2. Detect default branch per repo — use default_branch field from API response (do NOT hardcode main or master)

3. For each repo, collects:

   • Basic metadata: name, URL, language, stars, fork/archived status, description
   • Category classification (see below)
   • Test detection: check for test dirs, test files, test commands in CI
   • Codecov detection: check workflows for codecov references, check for codecov.yml
   • CI system: GitHub Actions, GitLab CI, Tekton, tox, etc.
   • Top 3 contributors (excluding bots)

   API efficiency: Fetch the recursive tree ONCE per repo. Extract workflow paths, test file paths, CI indicators, and language hints all from the same tree response. Cache workflow file contents when fetched for test detection and reuse for Codecov detection — do NOT fetch the same file twice.

   Language inference: When GitHub API returns null for language, infer from file extensions in the tree (e.g., *.go → Go, *.py → Python, *.ts → TypeScript). Use the most common extension. This prevents repos with code from being misclassified as no-language.

4. Writes CSV sorted by repo name

5. Saves progress to <org>-audit-progress.json every 10 repos (enables resume on interruption)

Category Classification

Classify each repo into one of (check in this order — first match wins):

• archived — archived/deprecated (check BEFORE fork — archived forks are just archived)
• fork — fork of upstream project
• documentation — docs-only repos (reStructuredText, HTML, MDX, no app code). Language = MDX, HTML, CSS, or reStructuredText triggers this
• sample/test — example, sample, demo, or test repos. Match "sample", "demo", "example", "quickstart", "test" ANYWHERE in name (not just prefix), but exclude repos with substantial source code
• ci-tooling — reusable CI actions/workflows. Detect by: action.yml or action.yaml at repo root, or name contains "actions" and repo has no application source code
• configuration — config-only repos (renovate config, shared settings). Detect by: name contains "config", "renovate-config", "settings", AND repo has no programming language or only YAML/JSON
• container-image — Dockerfile-only, no application logic
• infrastructure — deployment manifests, Helm charts, GitOps config
• catalog — pipeline/task catalogs (Tekton, CI definitions)
• application — has source code, potential for tests (default/fallback)

Test Detection

Check in this order:

GitHub repos:

1. CI workflows — scan .github/workflows/*.yml for test commands: go test, pytest, npm test, make test, tox, coverage run, jest, vitest, unittest, nox
2. Test directories — check for tests/, test/, tests/unit/, tests/e2e/, integration-tests/
3. Language-specific — package.json scripts for JS/TS, *_test.go for Go

GitLab repos:

1. CI config — scan .gitlab-ci.yml for test stages/jobs: Look for stage names containing test, job scripts containing go test, pytest, npm test, make test, tox, coverage run
2. Test directories — same as GitHub
3. Language-specific — same as GitHub
4. include: directives — note if .gitlab-ci.yml uses include: (may pull test jobs from templates — mark as likely if includes exist but no explicit test commands found)

Values: yes, likely, unknown, n/a (for skipped categories)

Codecov Detection

From CI config — scan workflow files for:

• codecov/codecov-action or codecov CLI usage
• use_oidc: true vs CODECOV_TOKEN
• flags: configuration
• codecov.yml or .codecov.yml config file

From Codecov API (optional, if user has Codecov access):

• GET https://app.codecov.io/api/v2/github/{owner}/repos/{repo}/ — check if repo exists on Codecov
• GET https://app.codecov.io/api/v2/github/{owner}/repos/{repo}/commits/ — check for recent coverage uploads
• Requires CODECOV_TOKEN (API token from codecov.io account settings)
• If Codecov API available, add Last Coverage Upload and Coverage % columns

For GitLab: check .gitlab-ci.yml for coverage: keyword regex, artifacts: reports: coverage_report: and codecov uploader usage.

Values: yes, config-only, no, n/a

Skip Deep Scan

For archived, fork, documentation, container-image, sample/test, ci-tooling, configuration categories — skip workflow/test analysis, set fields to n/a.

Rate Limiting & Error Handling

GitHub:

• Check api.github.com/rate_limit before and after
• Add time.sleep(0.15-0.3) between API calls
• Warn if <500 calls remaining
• On 403 with X-RateLimit-Remaining: 0, calculate wait from X-RateLimit-Reset and ask user

GitLab:

• Check RateLimit-Remaining response header
• Default 10 req/sec for authenticated, 5 for unauthenticated
• Respect Retry-After header on 429

Retry logic:

• On 5xx or network timeout: retry up to 3 times with exponential backoff (1s, 2s, 4s)
• On 404 for specific repo content (workflow files, codecov.yml): treat as "not found", do NOT retry
• On 403 (not rate limit): log warning, skip repo, continue audit

Progress & Resume:

• Save completed repos to <org>-audit-progress.json every 10 repos
• On startup, check for progress file — if found, ask user: resume or start fresh?
• Progress file stores: org name, timestamp, list of completed repo names + their data
• Print progress: [42/301] Scanning repo-name... to show advancement

Step 3: CSV Output Format

Columns (in order):

Repository, Onboard, URL, Language, Stars, Fork, Archived, Category, Description,
Has Unit Tests, Has E2E Tests, Has Codecov, CI System, Codecov Details,
Test Details, Contributor 1, Contributor 2, Contributor 3

File name: <org>-audit.csv

Onboard Column

The last column Onboard is a pre-selection flag for the coverage-jira-tasks skill. Set it to TRUE for repos the audit thinks are worth onboarding to Codecov, FALSE otherwise.

Selection logic — set TRUE when ALL of these hold:

• Category = application
• Not a fork, not archived
• Has a programming language (not just Makefile/Dockerfile)
• Has unit tests (yes or likely) OR has Codecov already (yes or config-only)

This gives the user a pre-filtered list they can review in Google Sheets (checkboxes render as clickable toggles). The coverage-jira-tasks skill reads this column to know which repos to create tasks for — no manual repo selection needed.

Important: This is a suggestion, not a decision. The user curates the checkboxes in the spreadsheet before downloading as CSV.

Step 3.5: Verify CSV Output

After writing CSV, verify it by reading first 5 rows with Python's csv module:

python3 -c "import csv; r=csv.DictReader(open('org-audit.csv')); [print(dict(row)) for row in list(r)[:5]]"

Do NOT use column -s',' -t — it breaks on quoted fields containing commas (e.g., "GitHub Actions, Tekton, Make").

Also sanitize description fields before writing: strip newlines, replace commas in descriptions with semicolons, and truncate to 200 chars.

Step 4: Print Summary Stats

After CSV generation, print:

Total repos:              N
Application repos:        N
Forks:                    N
Archived:                 N
Has unit tests:           N
Has Codecov:              N
Gap (tests, no Codecov):  N

The gap number = repos with tests but no Codecov. This is the primary onboarding opportunity.

Bot Exclusion List

Filter these from contributor lists: dependabot[bot], dependabot-preview[bot], github-actions[bot], renovate[bot], mergify[bot], codecov[bot], pre-commit-ci[bot], snyk-bot, mend-bolt-for-github[bot], ansibullbot, ansibot, patchback[bot], and any login ending in [bot].

Example

User: "Audit the ansible GitHub org for coverage status"

Result: ansible-audit.csv with 301 rows + summary showing 74 repos with tests, 16 with Codecov, 58 gaps.
