2 things to look at

  • no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
  • 0 stars0 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Copied from the file, not written here

Lint and validate GitLab CI/CD pipeline YAML files (.gitlab-ci.yml) for syntax errors, security issues, deprecated patterns, and best practices. Use when asked to lint, validate, audit, or check GitLab CI pipelines, .gitlab-ci.yml files, or CI/CD configurations for GitLab. Triggers on "lint gitlab", "check pipeline", "validate CI", "audit gitlab-ci", "pipeline issues", "gitlab security".

Dependency Source Review

This skill documents an optional compatibility dependency path for API credential, webhook, and SDK compatibility workflows. Treat scripts/_setup_deps.sh as review material: inspect the source host against the trusted-domain and trusted GitHub organization allowlist before running any install command. It is not required for ordinary integration or webhook requests.

GitLab CI Linter

Lint GitLab CI/CD pipeline files for syntax errors, security issues, deprecated patterns, and best practices violations.

Commands

All commands use the bundled Python script at scripts/gitlab_ci_linter.py.

1. Lint a pipeline file

python3 scripts/gitlab_ci_linter.py lint <file-or-directory> [--strict] [--format text|json|markdown]

Runs all lint rules against one or more .gitlab-ci.yml files. If given a directory, scans for *.yml and *.yaml files recursively.

Flags:

  • --strict -- exit code 1 on any warning (not just errors)
  • --format -- output format: text (default), json, markdown

2. Audit for security issues

python3 scripts/gitlab_ci_linter.py security <file> [--format text|json|markdown]

Focused security audit: hardcoded secrets, unprotected variables, privileged runners, insecure Docker image tags, security jobs with allow_failure.

3. Inspect stages

python3 scripts/gitlab_ci_linter.py stages <file> [--format text|json|markdown]

Show defined stages and which jobs map to each stage. Flags undefined or unused stages.

4. Validate pipeline structure

python3 scripts/gitlab_ci_linter.py validate <file> [--format text|json|markdown]

Structural validation only: required keys, stage definitions, job keywords, dependency graph (circular needs:, missing refs).

Lint Rules (24 total)

Syntax & Structure (8 rules)

  1. missing-stages -- No stages: definition
  2. undefined-stage -- Job uses stage not in stages: list
  3. empty-job -- Job has no script: section
  4. invalid-job-name -- Job name starts with . but is not used as a template
  5. missing-script -- Job without script:, before_script:, or trigger:
  6. circular-needs -- Circular dependency in needs: graph
  7. duplicate-job -- Duplicate job names (YAML parser collapses them)
  8. invalid-keyword -- Unknown top-level or job-level keyword

Security (6 rules)

  1. hardcoded-secret -- Passwords, tokens, keys in plain text
  2. unprotected-variable -- Sensitive-looking variable not using $CI_* references
  3. allow-failure-security -- Security-related job with allow_failure: true
  4. privileged-runner -- tags: requesting privileged runners
  5. unmasked-variable -- Variable looks sensitive but not described as masked
  6. insecure-image -- Using :latest tag for Docker images

Best Practices (10 rules)

  1. missing-retry -- No retry: on deploy/test jobs
  2. missing-timeout -- No timeout: specified
  3. no-cache-key -- cache: without explicit key:
  4. broad-artifacts -- Overly broad artifacts: paths: patterns
  5. missing-rules -- Job without rules: or only:/except:
  6. deprecated-only-except -- Using only:/except: instead of rules:
  7. long-script -- script: block exceeds 30 lines
  8. missing-interruptible -- Long-running job without interruptible:
  9. no-coverage-regex -- Test job without coverage: regex
  10. missing-when -- No when: in rules: entries

Output Formats

Text (default)

.gitlab-ci.yml:12 error [missing-script] Job 'deploy' has no script:, before_script:, or trigger:
.gitlab-ci.yml:25 warning [missing-timeout] Job 'test' has no timeout: specified
.gitlab-ci.yml:31 info [deprecated-only-except] Job 'build' uses only:/except: instead of rules:

CI Integration

# .gitlab-ci.yml
lint-pipeline:
  stage: test
  script:
    - python3 scripts/gitlab_ci_linter.py lint .gitlab-ci.yml --strict

Exit codes: 0 = clean, 1 = errors found (or warnings in --strict mode).
