Reviewing Claude Config

Reviewing Claude Configuration

Instructions

IMPORTANT: Use structured thinking throughout your review process. Plan your analysis before providing feedback. This improves accuracy and catches critical security issues.

Step 1: Detect File Type

Determine the primary file type(s) being reviewed:

Detection Rules:

• Agents: Changes to .claude/agents/*.md or plugins/*/agents/*.md
• Skills: Changes to skill.md files or skill support files (checklists, references, examples)
• CLAUDE.md: Changes to CLAUDE.md files (any location: project root, .claude/, or subdirectories)
• Prompts/Commands: Changes to .claude/prompts/*.md or .claude/commands/*.md
• Settings: Changes to .claude/settings.json or .claude/settings.local.json

If multiple types modified, review each with appropriate checklist.

Step 2: Execute Security Scan (ALWAYS)

CRITICAL CHECKS (perform for ALL Claude config reviews):

Run these mental checks immediately:

• settings.local.json NOT in git (check changed files list)
• No hardcoded credentials in any modified files
• Permissions scoped appropriately (if settings.json modified)
• No API keys, tokens, or passwords in plaintext

If ANY security issue found: Flag as CRITICAL immediately, stop and report.

Consult reference/security-patterns.md for detailed security checks and detection commands.

Step 3: Load Appropriate Checklist

Based on detected file type, read and follow the relevant checklist:

• Agents → checklists/agents.md (YAML, tool access security, model selection, system prompts)
• Skills → checklists/skills.md (structure, YAML, progressive disclosure, quality)
• CLAUDE.md → checklists/claude-md.md (clarity, references, no duplication)
• Prompts/Commands → checklists/prompts.md (purpose, session context, skill references)
• Settings → checklists/settings.md (security, permissions scoping)

The checklist provides:

• Multi-pass review strategy
• What to check and what to skip
• Structured thinking guidance
• Common issues and red flags

Step 4: Consult Reference Materials As Needed

Load reference files only when needed for specific questions:

• Issue prioritization → reference/priority-framework.md (CRITICAL vs IMPORTANT vs SUGGESTED vs OPTIONAL)
• Security patterns → reference/security-patterns.md (detection commands, fix examples)
• Claude Code requirements → reference/claude-code-requirements.md (YAML frontmatter, model selection, tool names, progressive disclosure, settings conventions)

Step 5: Document Findings

This section defines the standard output format for ALL Claude config reviews. Checklists reference this section rather than duplicating content.

CRITICAL: Use inline comments on specific lines, NOT one large summary comment.

Inline Comment Rules:

• Create separate comment for EACH specific issue on the exact line
• Do NOT create one large summary comment with all issues
• Do NOT update existing comments - always create new comments
• Include specific fix with code example when applicable
• Explain rationale (why this matters)

Comment Format:

**[file:line]** - [PRIORITY]: [Issue description]

[Specific fix with code example if applicable]

[Rationale explaining why this matters]

Reference: [documentation link if applicable]

Example inline comment:

**.claude/skills/my-skill/skill.md:1** - CRITICAL: Missing YAML frontmatter

Skills require YAML frontmatter to be discoverable by Claude Code:

\```yaml
---
name: my-skill
description: Clear description with activation triggers
---
\```

Without frontmatter, the skill won't be recognized by Claude Code.

Reference: Anthropic Skills Documentation

When to use inline vs summary:

• Inline comment: Specific issue, recommendation, or question (use file:line format)
• Summary comment: Overall assessment, recommendation (APPROVE or REQUEST CHANGES)

Load the specific example relevant to your file type (on-demand only, not upfront):

• Agents → examples/example-agent-review.md
• Skills → examples/example-skill-review.md
• CLAUDE.md → examples/example-claude-md-review.md
• Settings → examples/example-settings-review.md
• Prompts → examples/example-prompts-review.md

Core Principles

• Security first: Always check for committed settings, secrets, overly broad permissions
• Structure matters: YAML frontmatter, file references, progressive disclosure, line limits
• Quality counts: Clear instructions, examples, proper emphasis, structured thinking
• Token efficiency: Progressive disclosure, appropriate file sizes, on-demand loading
• Actionable feedback: Say what to do and why, not just what's wrong
• Constructive tone: Focus on code/config, not people; explain rationale
