# Audit Agents/Skills/Commands Quality
Comprehensive quality audit for Claude Code agents, skills, and commands. Scores each file on weighted criteria with production readiness grading.
## Arguments
- `[path]` - Directory to audit (default: current project `.claude/`)
- `--fix` - Generate fix suggestions for failing criteria
- `--verbose` - Show details for all criteria (not just failures)
## Usage
```bash
/audit-agents-skills # Audit current project
/audit-agents-skills --fix # Audit + fix suggestions
/audit-agents-skills ~/other-repo # Audit another project
/audit-agents-skills --verbose # Full details for all criteria
```
---
## Phase 1: Discovery
**Objective**: Locate and classify all agents, skills, and commands
### Steps
1. **Scan directories**:
```
.claude/agents/
.claude/skills/
.claude/commands/
examples/agents/ (if exists)
examples/skills/ (if exists)
examples/commands/ (if exists)
```
2. **Classify files**:
- **Agent**: File in `agents/` directory with YAML frontmatter containing `tools:` field
- **Skill**: File in `skills/` directory OR has `SKILL.md` name OR frontmatter with `allowed-tools:` field
- **Command**: File in `commands/` directory with frontmatter containing `name:` and `description:`
3. **Display summary**:
```
Found: X agents, Y skills, Z commands
```
---
## Phase 2: Audit Individual Files
Each file type is scored on **weighted criteria**. Maximum scores:
- **Agents**: 32 points
- **Skills**: 32 points
- **Commands**: 20 points
### Agents (32 points max)
#### Identity (weight: 3x) - 12 points
| Criterion | Points | Detection |
|-----------|--------|-----------|
| Clear `name` field | 3 | Frontmatter YAML has `name:` field that's descriptive (not generic like "agent1") |
| `description` with triggers | 3 | Description contains "when", "use", or "trigger" keywords indicating activation context |
| `model` specified | 3 | Frontmatter has `model:` field (sonnet/haiku/opus) |
| `tools` restricted appropriately | 3 | Tools list doesn't include Bash unless justified, or includes explanation for risky tools |
**Rationale**: Identity determines **discoverability** and **activation**. If users can't locate or invoke the agent, downstream quality is irrelevant.
#### Prompt Quality (weight: 2x) - 8 points
| Criterion | Points | Detection |
|-----------|--------|-----------|
| Role defined | 2 | Contains "You are" or "Your role" statement defining agent persona |
| Output format specified | 2 | Has section titled "Output", "Format", or "Deliverables" specifying expected structure |
| Scope/limits defined | 2 | Has section defining scope, triggers, or when NOT to use the agent |
| Anti-hallucination measures | 2 | Contains keywords: "verify", "cite", "source", "evidence", or warnings against hallucination |
**Rationale**: Prompt quality determines **reliability** and **accuracy** of agent responses.
#### Validation (weight: 1x) - 4 points
| Criterion | Points | Detection |
|-----------|--------|-----------|
| 3+ usage examples | 1 | Has "Examples", "Usage", or "Scenarios" section with at least 3 distinct examples |
| Edge cases documented | 1 | Mentions "edge case", "error", "failure", or "limitation" scenarios |
| Integration documented | 1 | References other agents, skills, or tools it works with |
| Error handling described | 1 | Mentions "fallback", "recovery", "error handling", or failure modes |
**Rationale**: Validation ensures **robustness** through comprehensive testing scenarios.
#### Design (weight: 2x) - 8 points
| Criterion | Points | Detection |
|-----------|--------|-----------|
| Single responsibility | 2 | File size <5000 tokens AND description is focused (not "general purpose" or multiple verbs) |
| No duplication | 2 | Description doesn't overlap significantly with other agents (>50% keyword similarity check) |
| Composable (skills references) | 2 | References skills or other agents it can invoke, showing modularity |
| Reasonable token budget | 2 | File size <8000 tokens (avoids context bloat) |
**Rationale**: Design patterns determine **maintainability** and **scalability** of agent architecture.
---
### Skills (32 points max)
#### Structure (weight: 3x) - 12 points
| Criterion | Points | Detection |
|-----------|--------|-----------|
| Valid SKILL.md or frontmatter | 3 | File named `SKILL.md` OR has YAML frontmatter with `name:` field |
| `name` valid | 3 | Name is lowercase, 1-64 chars, matches pattern `[a-z0-9-]+` (no spaces/special chars) |
| `description` non-empty | 3 | Description field exists and is >20 characters |
| `allowed-tools` specified | 3 | Frontmatter has `allowed-tools:` field listing tool permissions |
**Rationale**: Structure compliance ensures **spec compatibility** with Claude Code runtime.
#### Content (weight: 2x) - 8 points
| Criterion | Points | Detection |
|-----------|--------|-----------|
| Methodology/workflow described | 2 | Has section titled "Methodology", "Workflow", "Process", or numbered steps |
| Output format specified | 2 | Has section specifying deliverable format (Markdown, JSON, report structure) |
| Examples provided | 2 | Has "Examples", "Usage", or "Scenarios" section with concrete instances |
| Checklists included | 2 | Contains Markdown checkbox syntax `- [ ]` or `- [x]` for actionable items |
**Rationale**: Content richness determines **usability** and **learning curve**.
#### Technical (weight: 1x) - 4 points
| Criterion | Points | Detection |
|-----------|--------|-----------|
| Scripts have error handling | 1 | If bundled scripts exist, contain `set -e`, `trap`, or `|| exit` patterns |
| No hardcoded paths | 1 | No absolute paths like `/Users/`, `/home/`, `C:\` in code or instructions |
| No secrets | 1 | No keywords: "password", "secret", "token", "api_key", "credentials" in plaintext |
| Dependencies documented | 1 | If external tools required, has "Requirements", "Dependencies", or "Prerequisites" section |
**Rationale**: Technical hygiene prevents **portability issues** and **security risks**.
#### Design (weight: 2x) - 8 points
| Criterion | Points | Detection |
|-----------|--------|-----------|
| Single responsibility | 2 | Description is focused on one domain (not "general" or multi-purpose) |
| Clear triggers | 2 | Has section defining "When to use", "Triggers", or "Activation criteria" |
| No overlap with other skills | 2 | Description doesn't duplicate >50% of keywords from other skills in project |
| Portable | 2 | No Claude Code-specific extensions that break portability (check for custom APIs) |
**Rationale**: Design determines **findability** and **maintainability** across projects.
---
### Commands (20 points max)
#### Structure (weight: 3x) - 12 points
| Criterion | Points | Detection |
|-----------|--------|-----------|
| Valid frontmatter | 3 | Has YAML frontmatter with both `name:` and `description:` fields |
| `argument-hint` if takes args | 3 | If `$ARGUMENTS` variable is used in body, frontmatter has `argument-hint:` field |
| Step-by-step workflow | 3 | Body contains numbered sections (1., 2., 3.) or clear phase structure |
| Usage examples | 3 | Has section titled "Usage", "Examples", or shows invocation patterns |
**Rationale**: Structure determines **usability** and **learnability** for command users.
#### Quality (weight: 2x) - 8 points
| Criterion | Points | Detection |
|-----------|--------|-----------|
| Error handling | 2 | Mentions "error", "failure", "fallback", or conditional paths for failures |
| Output format defined | 2 | Specifies what command outputs (report, file, summary) and its structure |
| Validation gates | 2 | Contains checkpoints, verification steps, or "before proceeding" checks |
| Arguments parsed properly | 2 | If takes args, shows how to parse/validate `$ARGUMENTS` (default values, validation) |
**Rationale**: Quality determines **reliability** and **production readiness**.

## Phase 3: Scoring
### Individual File Score
```
Score = (Points Obtained / Max Points) × 100
```
**Example**: Agent scores 26/32 points → 81% score
### Grade Assignment
| Grade | Score Range | Status |
|-------|-------------|--------|
| A | 90-100% | Production-ready ✅ |
| B | 80-89% | Good (production threshold) ⚠️ |
| C | 70-79% | Needs improvement 🔧 |
| D | 60-69% | Significant gaps ⚠️ |
| F | <60% | Critical issues |
**Production Threshold**: 80% (Grade B or higher)
### Overall Project Score
Weighted average by file type:
```
Overall = (Σ Agent Scores × Agent Count + Σ Skill Scores × Skill Count + Σ Command Scores × Command Count) / Total Files
```
---
## Phase 4: Report Generation
### Report Structure
```markdown
# Audit: Agents/Skills/Commands
**Project**: {path}
**Date**: {date}
**Overall Score**: {score}% ({grade})
**Files Audited**: {total} ({n} agents, {n} skills, {n} commands)
**Production Ready**: {count} files ({percentage}%)
---
## Summary
| Type | Files | Avg Score | Grade | Production Ready |
|------|-------|-----------|-------|------------------|
| Agents | X | Y% | Z | N/X (%) |
| Skills | X | Y% | Z | N/X (%) |
| Commands | X | Y% | Z | N/X (%) |
---
## Individual Scores
| File | Type | Score | Grade | Top Issues |
|------|------|-------|-------|------------|
| agent-name.md | Agent | 85% | B | Missing anti-hallucination measures, no edge cases |

3. List compatible skills/agents for composition patterns
</details>
---
## Recommendations (Prioritized)
### High Priority (Critical for production)
1. **Add error handling to 8 files**
- Files: [list]
- Action: Add error handling sections, define fallback behaviors
2. **Remove hardcoded paths from 5 files**
- Files: [list]
- Action: Replace with `$HOME`, relative paths, or env vars
### Medium Priority (Improves quality)
3. **Add usage examples to 4 files**
- Files: [list]
- Action: Create "Examples" section with 3+ scenarios
4. **Define output formats in 3 files**
- Files: [list]
- Action: Specify deliverable structure (Markdown/JSON/report)
### Low Priority (Polish)
5. **Add integration docs to 2 files**
- Files: [list]
- Action: List compatible agents/skills for composition
---
## Next Steps
1. Review failures: Focus on Grade D/F files first
2. Run with `--fix` for automated suggestions
3. Re-audit after improvements to track progress
4. Aim for 80%+ (Grade B) across all files for production readiness
```
---
## Phase 5: Fix Mode (Optional)
**Trigger**: `--fix` flag
For each failing criterion, generate specific fix suggestion:
### Example Fix Suggestions
**File**: `agent-name.md`
**Issue**: Missing anti-hallucination measures (2 pts lost)
**Suggested Fix**:
```markdown
Add this section after the "Methodology" section:
## Source Verification
- Always cite sources for factual claims
- Use phrases like "According to [source]..." or "Based on [documentation]..."
- If uncertain, explicitly state "I don't have verified information on..."
- Never invent statistics, version numbers, or API details
```
**File**: `skill-debugging/scripts/analyze.sh`
**Issue**: No error handling (1 pt lost)
**Suggested Fix**:
```bash
Add to top of script:
set -e # Exit on error
trap 'echo "Error on line $LINENO"' ERR
# Replace risky commands:
curl https://api.example.com # ❌ No error check
curl https://api.example.com || { # ✅ Error handled
echo "API call failed"
exit 1
}
```
---
## Verbose Mode (Optional)
**Trigger**: `--verbose` flag
By default, report shows only **failed criteria**. Verbose mode shows **all criteria** with pass/fail status:
```markdown
### All Criteria (Verbose)
| Criterion | Status | Points | Notes |
|-----------|--------|--------|-------|
| Clear name | ✅ Pass | 3/3 | Name is "debugging-specialist" (descriptive) |
| Description with triggers | ✅ Pass | 3/3 | Contains "Use when debugging..." |
| Model specified | ❌ Fail | 0/3 | No `model:` field in frontmatter |
| Tools restricted | ⚠️ Partial | 2/3 | Includes Bash but no justification |
| ... | ... | ... | ... |
```

## Industry Context
**Source**: LangChain Agent Report 2026 (verified)
**Key Statistics**:
- 29.5% of organizations deploy agents without systematic evaluation
- 18% cite "agent bugs" as their top challenge
- Only 12% use automated quality checks
**Implication**: This audit addresses a **real industry gap**. Most teams deploy agents/skills without validation, leading to production issues. The 80% threshold (Grade B) aligns with industry best practices for production readiness.
**Comparison**: Manual checklists (like the Guide's Agent Validation Checklist on line 4921) are comprehensive but error-prone. Automated scoring reduces human error and provides quantitative metrics for tracking improvements over time.

## Related
- **Agent Validation Checklist** (guide line 4921): Manual 16-criteria checklist
- **Skill Validation** (guide line 5491): Spec compliance documentation
- **Examples**: `examples/agents/`, `examples/skills/`, `examples/commands/`
- **Advanced Audit**: Use `audit-agents-skills` skill (see `examples/skills/`) for comparative analysis vs templates
---
## Implementation Notes
### Detection Patterns
**Frontmatter Parsing**:
```python
import re
yaml_match = re.search(r'^---\n(.*?)\n---', content, re.DOTALL)
if yaml_match:
import yaml
frontmatter = yaml.safe_load(yaml_match.group(1))
```
**Keyword Detection** (case-insensitive):
```python
has_trigger = any(word in description.lower() for word in ['when', 'use', 'trigger'])
```
**Token Counting** (approximate):
```python
tokens = len(content.split()) * 1.3 # Rough estimate: 1 token ≈ 0.75 words
```
### Overlap Detection
Compare descriptions using Jaccard similarity:
```python
def jaccard_similarity(desc1, desc2):
words1 = set(desc1.lower().split())
words2 = set(desc2.lower().split())
intersection = words1 & words2
union = words1 | words2
return len(intersection) / len(union) if union else 0
# Flag if similarity > 0.5 (50% keyword overlap)
```
### Grade Color Coding (Terminal Output)
```python
COLORS = {
'A': '\033[92m', # Green
'B': '\033[93m', # Yellow
'C': '\033[93m', # Yellow
'D': '\033[91m', # Red
'F': '\033[91m' # Red
}
```

# Audit Agents/Skills/Commands (Advanced Skill)
Comprehensive quality audit system for Claude Code agents, skills, and commands. Provides quantitative scoring, comparative analysis, and production readiness grading based on industry best practices.
## Purpose
**Problem**: Manual validation of agents/skills is error-prone and inconsistent. According to the LangChain Agent Report 2026, 29.5% of organizations deploy agents without systematic evaluation, leading to "agent bugs" as the top challenge (18% of teams).
**Solution**: Automated quality scoring across 16 weighted criteria with production readiness thresholds (80% = Grade B minimum for production deployment).
**Key Features**:
- Quantitative scoring (32 points for agents/skills, 20 for commands)
- Weighted criteria (Identity 3x, Prompt 2x, Validation 1x, Design 2x)
- Production readiness grading (A-F scale with 80% threshold)
- Comparative analysis vs reference templates
- JSON/Markdown dual output for programmatic integration
- Fix suggestions for failing criteria
---
## Modes
| Mode | Usage | Output |
|------|-------|--------|
| **Quick Audit** | Top-5 critical criteria only | Fast pass/fail (3-5 min for 20 files) |
| **Full Audit** | All 16 criteria per file | Detailed scores + recommendations (10-15 min) |
| **Comparative** | Full + benchmark vs templates | Analysis + gap identification (15-20 min) |
**Default**: Full Audit (recommended for first run)
---
## Methodology
### Why These Criteria?
The 16-criteria framework is derived from:
1. **Claude Code Best Practices** (Ultimate Guide line 4921: Agent Validation Checklist)
2. **Industry Data** (LangChain Agent Report 2026: evaluation gaps)
3. **Production Failures** (Community feedback on hardcoded paths, missing error handling)
4. **Composition Patterns** (Skills should reference other skills, agents should be modular)
### Scoring Philosophy
**Weight Rationale**:
- **Identity (3x)**: If users can't find/invoke the agent, quality is irrelevant (discoverability > quality)
- **Prompt (2x)**: Determines reliability and accuracy of outputs
- **Validation (1x)**: Improves robustness but is secondary to core functionality
- **Design (2x)**: Impacts long-term maintainability and scalability
**Grade Standards**:
- **A (90-100%)**: Production-ready, minimal risk
- **B (80-89%)**: Good, meets production threshold
- **C (70-79%)**: Needs improvement before production
- **D (60-69%)**: Significant gaps, not production-ready
- **F (<60%)**: Critical issues, requires major refactoring
**Industry Alignment**: The 80% threshold aligns with software engineering best practices for production deployment (e.g., code coverage >80%, security scan pass rates).
---
## Workflow
### Phase 1: Discovery
1. **Scan directories**:
```
.claude/agents/
.claude/skills/
.claude/commands/
examples/agents/ (if exists)
examples/skills/ (if exists)
examples/commands/ (if exists)
```
2. **Classify files** by type (agent/skill/command)
3. **Load reference templates** (for Comparative mode):
```
guide/examples/agents/ (benchmark files)
guide/examples/skills/ (benchmark files)
guide/examples/commands/ (benchmark files)
```
### Phase 2: Scoring Engine
Load scoring criteria from `scoring/criteria.yaml`:
```yaml
agents:
max_points: 32
categories:
identity:
weight: 3
criteria:
- id: A1.1
name: "Clear name"
points: 3
detection: "frontmatter.name exists and is descriptive"
# ... (16 total criteria)
```
For each file:
1. Parse frontmatter (YAML)
2. Extract content sections
3. Run detection patterns (regex, keyword search)
4. Calculate score: `(points / max_points) × 100`
5. Assign grade (A-F)
### Phase 3: Comparative Analysis (Comparative Mode Only)
For each project file:
1. Find closest matching template (by description similarity)
2. Compare scores per criterion
3. Identify gaps: `template_score - project_score`
4. Flag significant gaps (>10 points difference)
**Example**:
```
Project file: .claude/agents/debugging-specialist.md (Score: 78%, Grade C)
Closest template: examples/agents/debugging-specialist.md (Score: 94%, Grade A)
Gaps:
- Anti-hallucination measures: -2 points (template has, project missing)
- Edge cases documented: -1 point (template has 5 examples, project has 1)
- Integration documented: -1 point (template references 3 skills, project none)
Total gap: 16 points (explains C vs A difference)
```
### Phase 4: Report Generation
**Markdown Report** (`audit-report.md`):
- Summary table (overall + by type)
- Individual scores with top issues
- Detailed breakdown per file (collapsible)
- Prioritized recommendations
**JSON Output** (`audit-report.json`):
```json

],
"top_issues": [
{
"issue": "Missing error handling",
"affected_files": 8,
"impact": "Runtime failures unhandled",
"priority": "high"
}
]
}
```
### Phase 5: Fix Suggestions (Optional)
For each failing criterion, generate **actionable fix**:
```markdown
### File: .claude/agents/debugging-specialist.md
**Issue**: Missing anti-hallucination measures (2 points lost)
**Fix**:
Add this section after "Methodology":
## Source Verification
- Always cite sources for technical claims
- Use phrases: "According to [documentation]...", "Based on [tool output]..."
- If uncertain, state: "I don't have verified information on..."
- Never invent: statistics, version numbers, API signatures, stack traces
**Detection**: Grep for keywords: "verify", "cite", "source", "evidence"
```

---
## Detection Patterns
### Frontmatter Parsing
```python
import yaml
import re
def parse_frontmatter(content):
match = re.search(r'^---\n(.*?)\n---', content, re.DOTALL)
if match:
return yaml.safe_load(match.group(1))
return None
```
### Keyword Detection
```python
def has_keywords(text, keywords):
text_lower = text.lower()
return any(kw in text_lower for kw in keywords)
# Example
has_trigger = has_keywords(description, ['when', 'use', 'trigger'])
has_error_handling = has_keywords(content, ['error', 'failure', 'fallback'])
```
### Overlap Detection (Duplication Check)
```python
def jaccard_similarity(text1, text2):
words1 = set(text1.lower().split())
words2 = set(text2.lower().split())
intersection = words1 & words2
union = words1 | words2
return len(intersection) / len(union) if union else 0
# Flag if similarity > 0.5 (50% keyword overlap)
if jaccard_similarity(desc1, desc2) > 0.5:
issues.append("High overlap with another file")
```
### Token Counting (Approximate)
```python
def estimate_tokens(text):
# Rough estimate: 1 token ≈ 0.75 words
word_count = len(text.split())
return int(word_count * 1.3)
# Check budget
tokens = estimate_tokens(file_content)
if tokens > 5000:
issues.append("File too large (>5K tokens)")
```

- **43%** report difficulty maintaining agent quality over time
- **Top issues**: Hallucinations (31%), poor error handling (28%), unclear triggers (22%)
**Implications**:
1. **Automation gap**: Most teams rely on manual checklists (error-prone at scale)
2. **Quality debt**: Agents deployed without validation accumulate technical debt
3. **Maintenance burden**: 43% struggle with quality over time (no tracking system)
**This skill addresses**:
- Automation: Replaces manual checklists with quantitative scoring
- Tracking: JSON output enables trend analysis over time
- Standards: 80% threshold provides clear production gate

## Output Examples
### Quick Audit (Top-5 Criteria)
```markdown
# Quick Audit: Agents/Skills/Commands
**Files**: 15 (5 agents, 8 skills, 2 commands)
**Critical Issues**: 3 files fail top-5 criteria
## Top-5 Criteria (Pass/Fail)
| File | Valid Name | Has Triggers | Error Handling | No Hardcoded Paths | Examples |
|------|------------|--------------|----------------|--------------------|----------|
| agent1.md | ✅ | ✅ | ❌ | ✅ | ❌ |
| skill2/ | ✅ | ❌ | ✅ | ❌ | ✅ |
## Action Required
1. **Add error handling**: 5 files
2. **Remove hardcoded paths**: 3 files
3. **Add usage examples**: 4 files
```
### Full Audit
See Phase 4: Report Generation above for full structure.
### Comparative (Full + Benchmarks)
```markdown
# Comparative Audit
## Project vs Templates
| File | Project Score | Template Score | Gap | Top Missing |
|------|---------------|----------------|-----|-------------|
| debugging-specialist.md | 78% (C) | 94% (A) | -16 pts | Anti-hallucination, edge cases |
| testing-expert/ | 85% (B) | 91% (A) | -6 pts | Integration docs |
## Recommendations
Focus on these gaps to reach template quality:
1. **Anti-hallucination measures** (8 files): Add source verification sections
2. **Edge case documentation** (5 files): Add failure scenario examples
3. **Integration documentation** (4 files): List compatible agents/skills
```
---
## Usage
### Basic (Full Audit)
```bash
# In Claude Code
Use skill: audit-agents-skills
# Specify path
Use skill: audit-agents-skills for ~/projects/my-app
```
### With Options
```bash
# Quick audit (fast)
Use skill: audit-agents-skills with mode=quick
# Comparative (benchmark analysis)
Use skill: audit-agents-skills with mode=comparative
# Generate fixes
Use skill: audit-agents-skills with fixes=true
# Custom output path
Use skill: audit-agents-skills with output=~/Desktop/audit.json
```
### JSON Output Only
```bash
# For programmatic integration
Use skill: audit-agents-skills with format=json output=audit.json
```
---
## Integration with CI/CD
### Pre-commit Hook
```bash
#!/bin/bash
# .git/hooks/pre-commit
# Run quick audit on changed agent/skill/command files
changed_files=$(git diff --cached --name-only | grep -E "^\.claude/(agents|skills|commands)/")
if [ -n "$changed_files" ]; then
echo "Running quick audit on changed files..."
# Run audit (requires Claude Code CLI wrapper)
# Exit with 1 if any file scores <80%
fi
```
### GitHub Actions
```yaml
name: Audit Agents/Skills
on: [pull_request]
jobs:
audit:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v3
- name: Run quality audit
run: |
# Run audit skill
# Parse JSON output
# Fail if overall_score < 80
```
---
## Comparison: Command vs Skill
| Aspect | Command (`/audit-agents-skills`) | Skill (this file) |
|--------|----------------------------------|-------------------|
| **Scope** | Current project only | Multi-project, comparative |
| **Output** | Markdown report | Markdown + JSON |
| **Speed** | Fast (5-10 min) | Slower (10-20 min with comparative) |
| **Depth** | Standard 16 criteria | Same + benchmark analysis |
| **Fix suggestions** | Via `--fix` flag | Built-in with recommendations |
| **Programmatic** | Terminal output | JSON for CI/CD integration |
| **Best for** | Quick checks, dev workflow | Deep audits, quality tracking |
**Recommendation**: Use command for daily checks, skill for release gates and quality tracking.
---
## Maintenance
### Updating Criteria
Edit `scoring/criteria.yaml`:
```yaml
agents:
categories:
identity:
criteria:
- id: A1.5 # New criterion
name: "API versioning specified"
points: 3
detection: "mentions API version or compatibility"
```
Version bump: Increment `version` in frontmatter when criteria change.
### Adding File Types
To support new file types (e.g., "workflows"):
1. Add to `scoring/criteria.yaml`:
```yaml
workflows:
max_points: 24
categories: [...]
```
2. Update detection logic (file path patterns)
3. Update report templates
