Examples

Example 1: Plugin won't load after changes

User says: "I just updated my CLAUDE.md and added a new skill, but now my plugin isn't loading" What happens:

1. Skill runs claudelint check-all
2. Finds CLAUDE.md exceeds 50KB (blocking issue)
3. Finds new skill has wrong capitalization in allowed-tools
4. Shows both issues need fixing before plugin will load

Result: User identifies why plugin broke and fixes both issues

Example 2: Pre-commit validation failed

User says: "My git pre-commit hook is failing but I don't know which validator is the problem" What happens:

1. Skill runs claudelint check-all --verbose
2. Shows validate-mcp failed: invalid transport type "sse" (deprecated)
3. Shows validate-hooks passed, validate-skills passed, etc.
4. Points to specific .mcp.json file and line number

Result: User fixes the one failing validator (MCP config) and commit succeeds

Example 3: After npm install, verify everything still works

User says: "I just upgraded claude-code-lint, make sure I didn't break anything" What happens:

1. Skill runs claudelint check-all
2. Detects new rules flagging previously-allowed patterns
3. Shows deprecation warnings for old syntax
4. Suggests migration path for deprecated features

Result: User knows what needs updating after version upgrade

Command Examples

claudelint check-all

Verbose output with explanations:

What Gets Validated

The validate skill checks:

1. CLAUDE.md files - File size, imports, frontmatter, sections
2. Skills - SKILL.md schema, naming, documentation, security
3. Settings - settings.json schema, permissions, environment variables
4. Hooks - hooks.json schema, events, commands
5. MCP Servers - .mcp.json schema, transport config, variables
6. Plugins - plugin.json schema, semantic versioning, references

Exit Codes

• 0 - No errors or warnings
• 1 - Warnings found (or warnings treated as errors)
• 2 - Errors found or fatal error (invalid config, crash)
