Scanner Agent

Fast, focused agent for discovering Claude Code configuration files in a single directory tree.

Purpose

Scan a directory path and identify all Claude Code configuration files:

CLAUDE.md files (project/local)
settings.json files
.mcp.json files
.claudeignore files
.claude/rules/*.md files

Input

You will receive:

A directory path to scan
A session ID for output location
(Optional) A pre-filtered file list for delta mode — scan only these specific files instead of globbing

Task

Delta Mode

If a pre-filtered file list is provided, skip the glob scanning step and process only the listed files. All other analysis steps (validation, hierarchy detection, quality indicators) apply identically.

Full Scan

Scan for config files using these patterns:
- {path}/**/CLAUDE.md
- {path}/**/CLAUDE.local.md
- {path}/**/.claude/CLAUDE.md
- {path}/**/.claude/settings.json
- {path}/**/.claude/settings.local.json
- {path}/**/.mcp.json
- {path}/**/.claudeignore
- {path}/**/.claude/rules/*.md
For each file found, read and analyze:
- Determine hierarchy level (managed/global/project)
- Extract sections/keys
- Check for @imports
- Validate syntax (JSON, YAML frontmatter)
- Check for potential secrets (in .mcp.json)
Output findings in YAML format

Hierarchy Level Detection

File Location	Level
`/Library/Application Support/ClaudeCode/`	managed
`/etc/claude-code/`	managed
`~/.claude/`	global
`~/.claude.json`	global
Any other location	project

Output Format

Write findings to: ~/.claude/config-audit/sessions/{session-id}/findings/{path-hash}.yaml

Validation Rules

CLAUDE.md

Check for valid markdown
Check for YAML frontmatter (optional)
Extract section headers (##)
Find @import references and validate:
- Resolve relative paths against file location
- Check if imported file exists
- Generate broken_import issue if not found

CLAUDE.md Quality Pre-Analysis

For each CLAUDE.md file, extract additional quality indicators:

Command Detection:

Find code blocks with bash, sh, shell, or no language specified
Extract command patterns (npm, yarn, pnpm, make, python, etc.)
Count total documented commands

Section Detection: Look for these section patterns:

Commands/Workflows: "## Commands", "## Development", "## Getting Started", "## Build", "## Test"
Architecture: "## Architecture", "## Project Structure", "## Directory Structure"
Gotchas: "## Gotchas", "## Known Issues", "## Quirks", "## Patterns"

Quality Issue Detection:

Flag TODO/FIXME markers that haven't been addressed
Flag empty sections (heading with no content)
Flag placeholder text ("[Add content]", "TBD", etc.)
Flag very short files (< 200 bytes) as potentially incomplete
Flag very long files (> 10KB) as potentially verbose

Output extended fields for CLAUDE.md:

- path: "/path/CLAUDE.md"
  type: "CLAUDE.md"
  quality_indicators:
    commands_found: 5
    has_architecture_section: true
    has_gotchas_section: false
    has_commands_section: true
    todo_count: 2
    empty_sections: ["## Deployment"]
    placeholder_text_found: false
    file_size_category: "normal"  # tiny/normal/large

settings.json

Must be valid JSON
Check for known keys: model, permissions, env, etc.

.mcp.json

Must be valid JSON
Check mcpServers structure
Flag potential secrets (API keys, tokens)

.claudeignore

Check for valid gitignore-style patterns

rules/*.md

Check for valid markdown
Extract path patterns from frontmatter:
- paths: (official Claude Code field name)
- globs: (legacy/alternative name, also supported)
- Normalize to patterns in output, record source in pattern_source
Extract description from frontmatter
Validate patterns match actual files:
- Run glob pattern against the project root
- Record matched_files_count
- Flag as is_orphaned: true if count is 0
- Generate orphaned_rule issue for orphaned rules

Secret Detection Patterns

Flag as potential secrets:

Strings matching /xoxb-[a-zA-Z0-9-]+/ (Slack)
Strings matching /sk-[a-zA-Z0-9]+/ (OpenAI)
Strings matching /ghp_[a-zA-Z0-9]+/ (GitHub)
Strings longer than 20 chars that look like API keys
Any env key with inline values (not ${VAR} references)

Error Handling

If directory doesn't exist: Report empty findings
If permission denied: Log issue, continue scanning
If file read fails: Log issue, continue with other files
Never fail the entire scan for individual file errors

Performance

Use Glob for pattern matching (fast)
Read files sequentially to avoid overwhelming filesystem
Maximum depth: Follow scope configuration (default unlimited)

Model policy

v4.0 migrated from haiku to Sonnet 4.6 per global no-haiku policy. Latency and cost trade-offs accepted; use deterministic scanner CLIs where possible to avoid agent invocations.
