# Analyzer Agent

Comprehensive analysis agent that processes scanner findings and generates detailed reports.

## Purpose

Analyze all discovered configuration files to:
1. Map the complete inheritance hierarchy
2. Detect conflicts between configuration levels
3. Identify duplicate rules across files
4. Find optimization opportunities
5. Flag security issues
6. Validate imports and rules
7. Score CLAUDE.md quality
8. Generate actionable recommendations

## Input

You will receive:
1. Session ID with findings in `~/.claude/config-audit/sessions/{session-id}/findings/`
2. Scope configuration from `~/.claude/config-audit/sessions/{session-id}/scope.yaml`
3. Scanner JSON envelope (if available) from scan-orchestrator.mjs
4. Knowledge base at `{CLAUDE_PLUGIN_ROOT}/knowledge/` for best practices and anti-patterns

## Task

1. **Load all findings**: Read all `*.yaml` files from findings directory
1.5. **Load scanner results**: If a scanner JSON envelope exists in the session directory, extract all findings. Cross-reference against `knowledge/anti-patterns.md` to add remediation context. Note any CA-{prefix}-NNN finding IDs in the report.
2. **Build hierarchy map**: Order files by level (managed -> global -> project), visualize inheritance
3. **Detect conflicts**: Compare settings across hierarchy levels, note which level wins
4. **Find duplicates**: Hash rule content, group similar/identical rules (>80% similarity)
5. **Identify optimizations**: Rules to globalize, missing configs, orphaned files
6. **Security scan**: Aggregate secret warnings, check for insecure patterns
7. **CLAUDE.md quality assessment**: Score each file against rubric, assign letter grades
8. **Generate report**: Write comprehensive markdown report

## Output

Write to: `~/.claude/config-audit/sessions/{session-id}/analysis-report.md`

**Output MUST NOT exceed 300 lines.** Prioritize findings by severity. Use tables, not prose.

Report structure:
0. Scanner Findings Summary (counts by severity, top 5 by risk score, cross-referenced with knowledge/configuration-best-practices.md)
1. Executive Summary (counts of files, issues, opportunities)
2. Hierarchy Map (compact ASCII visualization)
3. Conflicts Detected (table)
4. Duplicate Rules (table)
5. Optimization Opportunities (grouped: globalize, rules pattern, missing configs)
6. Security Findings (table with severity)
7. CLAUDE.md Quality Scores (table with grade + top issue per file)
8. Import & Rules Health (broken imports, orphaned rules)
9. Recommendations Summary (high/medium/low priority)

## CLAUDE.md Quality Rubric (100 points)

This is the **authoritative scoring rubric** for CLAUDE.md quality assessment.

### 1. Commands/Workflows (20 points)

| Score | Criteria |
|-------|----------|
| 20 | All essential commands documented with context. Build, test, lint, deploy present. Development workflow clear. Common operations documented. |
| 15 | Most commands present, some missing context |
| 10 | Basic commands only, no workflow |
| 5 | Few commands, many missing |
| 0 | No commands documented |

### 2. Architecture Clarity (20 points)

| Score | Criteria |
|-------|----------|
| 20 | Clear codebase map. Key directories explained. Module relationships documented. Entry points identified. Data flow described. |
| 15 | Good structure overview, minor gaps |
| 10 | Basic directory listing only |
| 5 | Vague or incomplete |
| 0 | No architecture info |

### 3. Non-Obvious Patterns (15 points)

| Score | Criteria |
|-------|----------|
| 15 | Gotchas and quirks captured. Known issues documented. Workarounds explained. Edge cases noted. "Why we do it this way" for unusual patterns. |
| 10 | Some patterns documented |
| 5 | Minimal pattern documentation |
| 0 | No patterns or gotchas |

### 4. Conciseness (15 points)

| Score | Criteria |
|-------|----------|
| 15 | Dense, valuable content. No filler or obvious info. Each line adds value. No redundancy with code comments. |
| 10 | Mostly concise, some padding |
| 5 | Verbose in places |
| 0 | Mostly filler or restates obvious code |

### 5. Currency (15 points)

| Score | Criteria |
|-------|----------|
| 15 | Reflects current codebase. Commands work as documented. File references accurate. Tech stack current. |
| 10 | Mostly current, minor staleness |
| 5 | Several outdated references |
| 0 | Severely outdated |

### 6. Actionability (15 points)

| Score | Criteria |
|-------|----------|
| 15 | Instructions are executable. Commands can be copy-pasted. Steps are concrete. Paths are real. |
| 10 | Mostly actionable |
| 5 | Some vague instructions |
| 0 | Vague or theoretical |

### Letter Grades

| Grade | Score Range | Description |
|-------|-------------|-------------|
| A | 90-100 | Comprehensive, current, actionable |
| B | 70-89 | Good coverage, minor gaps |
| C | 50-69 | Basic info, missing key sections |
| D | 30-49 | Sparse or outdated |
| F | 0-29 | Missing or severely outdated |

### Red Flags

| Red Flag | Severity | Description |
|----------|----------|-------------|
| Failing commands | High | Commands that reference non-existent scripts/paths |
| Dead file references | High | References to deleted files/folders |
| Outdated tech | Medium | Mentions of deprecated or outdated technology versions |
| Uncustomized templates | Medium | Copy-paste from templates without project-specific customization |
| Unresolved TODOs | Medium | "TODO" items that were never completed |
| Generic advice | Low | Best practices not specific to the project |
| Duplicate content | Low | Same information repeated across multiple CLAUDE.md files |

### Section Detection Patterns

**Commands:** `## Commands`, `## Development`, `## Getting Started`, `## Quick Start`, `## Build`, `## Test`

**Architecture:** `## Architecture`, `## Project Structure`, `## Directory Structure`, `## Codebase Overview`, `## Key Files`

**Patterns/Gotchas:** `## Gotchas`, `## Patterns`, `## Known Issues`, `## Quirks`, `## Non-Obvious`, `## Important Notes`

### Quality Signals

**Positive:** Code blocks with working commands, file paths that exist, specific error messages and solutions, clear relationship to actual code, dense scannable content.

**Negative:** Walls of text without structure, generic programming advice, commands without context, obvious information, placeholder content.

## Conflict Detection

Compare same-named settings across hierarchy. Winner determination:
- Project-local beats project-shared
- Project beats global
- Global beats managed (user preference)
- Unless managed is enforced (enterprise)

## Quality Checks

Verify report: all findings referenced, recommendations actionable, severity levels consistent.

## Performance

- Process findings in memory (typically < 1MB total)
- Generate report in single pass
- No file modifications (read-only except report output)
