Ansible CoP Review

Important

• Do NOT skip any rule category — check all of them (unless the user requested a category filter).
• When a category does not apply (e.g., no templates exist), mark it N/A.
• Read redhat-cop-automation-good-practices-*.md for edge cases when a rule's applicability is unclear.
• Be precise about line numbers and file paths.
• If the rules are not available locally (no CLAUDE.md with Ansible rules or redhat-cop-automation-good-practices-*.md), fetch them from https://github.com/redhat-cop/automation-good-practices as a fallback.

Review all Ansible code in the current project (or the path/files the user specified via $ARGUMENTS) against every rule in CLAUDE.md and redhat-cop-automation-good-practices-*.md.

Review process

1. Determine review mode — Check what the user requested:

   • Full review (default) — review all Ansible files in the project.
   • Path/file review — review only the files or path the user specified.
   • Diff-aware review — if the user asks to review "changed files", "my changes", or similar, run git diff --name-only (and git diff --cached --name-only for staged changes) to get the list of modified files. Only review those files. Mention which base you are diffing against (e.g., HEAD, main).
   • Category filter — if the user asks to check only specific rule categories (e.g., "just check naming", "skip documentation"), apply only those categories. List which categories are being checked and which are skipped at the start of the report.

2. Discover scope — Based on the review mode, identify files to review. For full reviews, scan for all *.yml/*.yaml files, templates/, defaults/, vars/, meta/, tasks/, handlers/, inventory/, and README.md files in the working directory tree.

3. Run ansible-lint — If ansible-lint is available on the system, run it against the discovered files and capture its output. Cross-reference ansible-lint findings with CoP rules in the report — map each ansible-lint rule ID to the corresponding CoP category where applicable. If ansible-lint is not available, note this and proceed with the manual review only.

4. Parallel review for large projects — If the project contains multiple roles or a large number of files (more than 3 roles or 30+ files), use the Agent tool with subagents to review roles/components in parallel. Each subagent reviews one role or logical group of files against all applicable rule categories. Merge subagent results into a single report.

5. Check every applicable rule category against the discovered files:

   • Architecture — Landscape / Type / Function / Component hierarchy
   • Role naming — role-prefixed variables, __ internal prefix, no dashes, no special chars, tag prefixes
   • Variable placement — defaults vs vars, commented-out dangerous defaults, no user-facing vars in vars/main.yml
   • Idempotency & check mode — changed_when: on command/shell, idempotent module usage, re-run safety
   • Argument validation — meta/argument_specs.yml existence and completeness
   • File references — {{ role_path }} usage, no relative paths
   • Templates — {{ ansible_managed | comment }} header, backup: true, no timestamps
   • Platform support — include_vars loop pattern, first_found pattern, ansible_facts['...'] bracket notation
   • Fact gathering — minimum subset, graceful handling of gather_facts: false
   • Playbook structure — no mixed roles: + tasks:, tag safety, verbosity: on debug tasks
   • Inventory — structured directories, no vars in hosts file, no manual host loops
   • YAML style — 2-space indent, true/false booleans, line length under 120, folded scalars
   • Naming — snake_case everywhere, imperative task names, sub-task prefixes
   • Module usage — FQCN, loop: over with_*, import/include patterns
   • Collections — semantic versioning, README, LICENSE
   • Providers — $ROLENAME_provider pattern, auto-detection
   • Documentation — README.md with examples, variable specs, idempotency designation, rollback info

Severity levels

Classify every finding with one of these severity levels:

• ERROR — Must fix. Violates a MUST/NEVER/ALWAYS rule from CLAUDE.md. Examples: missing changed_when: on command: tasks, user-facing defaults in vars/main.yml, non-FQCN module names, yes/no booleans.
• WARNING — Should fix. Violates a best practice or SHOULD-level recommendation. Examples: missing backup: true on template tasks, missing README sections, no platform-specific variable loading.
• INFO — Suggestion. Opportunity to improve but not a rule violation. Examples: task could use a more descriptive name, variable could be documented better, a role could benefit from the provider pattern.

Report format

6. Report findings — Group findings by file, then by severity. For each violation:

   • Severity level: [ERROR], [WARNING], or [INFO]
   • The rule being violated (quote the rule text briefly)
   • File path and line number
   • The offending code snippet
   • The corrected code
   • If from ansible-lint: include the ansible-lint rule ID

7. Summary table — End with a markdown table:

   Rule Category	Status	Severity	Files Affected	Count
   Role naming	PASS/FAIL	ERROR/WARNING/INFO	file1, file2	N
   ...	...	...	...	...

   Include totals row: total ERRORs, WARNINGs, and INFOs.

8. Overall verdict — State whether the code is compliant or not, and list the top 3 highest-priority fixes (always prioritize ERRORs first).

Auto-fix

9. Offer to fix — After presenting the report, ask the user: "Would you like me to automatically fix these violations?"
   • If yes, apply fixes grouped by file, starting with ERRORs, then WARNINGs. Do not auto-fix INFO-level findings unless the user explicitly asks.
   • After applying fixes, re-run the review on the modified files to confirm all targeted violations are resolved.
   • Report what was fixed and what remains (if anything requires manual intervention, explain why).

Rules fallback

If the rules are not available locally (no CLAUDE.md with Ansible rules or redhat-cop-automation-good-practices-*.md), fetch them from https://github.com/redhat-cop/automation-good-practices as a fallback.
