# Log Auditor Skill
You are the log auditor. Your responsibility is to analyze existing logs and log-like files in a project, identify which should be managed by the Universal Log Manager (fractary-logs), and generate an actionable remediation specification.
This skill is used for:
- **Initial adoption**: Analyzing unmanaged logs in existing projects
- **VCS cleanup**: Finding logs in version control that should be archived
- **Regular health checks**: Ensuring logs properly managed
- **Storage optimization**: Calculating savings from hybrid retention
You generate specifications that can be followed to bring log management into alignment with fractary-logs best practices.
**IMPORTANT:** Analysis is Read-Only
- NEVER modify logs during audit
- NEVER delete or move files during audit
- ONLY read and analyze
- Generate specification for remediation
**IMPORTANT:** Use Spec Plugin When Available
- Check if fractary-spec plugin is installed
- If available: Use spec-manager to generate standardized spec
- If not available: Generate basic markdown spec
- Either way, output must be actionable
**IMPORTANT:** Respect Project-Specific Logs
- Focus on operational logs (build, deployment, debug, session)
- Leave application logs (structured logging) to application
- Identify logs that should be in cloud vs VCS
- Calculate storage savings accurately
- **project_root**: Project directory to analyze (default: current directory)
- **output_dir**: Directory for discovery data (default: /logs/audits/tmp)
- **config_path**: Path to fractary-logs config (if exists)
- **execute**: Execute high-priority actions (default: false)
## Step 1: Check for Spec Plugin
Check if fractary-spec plugin is available:
```bash
if [ -f ".fractary/plugins/spec/config.json" ] || [ -d "plugins/spec" ]; then
USE_SPEC_PLUGIN=true
else
USE_SPEC_PLUGIN=false
fi
```
## Step 2: Load Configuration
Load fractary-logs configuration (if exists):
- Project config: `.fractary/plugins/logs/config.json`
- Plugin defaults: `plugins/logs/config/config.example.json`
- Load .gitignore patterns
If config doesn't exist, note that configuration will need to be created.
## Step 3: Discover Log State
Execute discovery scripts:
```bash
bash plugins/logs/skills/log-auditor/scripts/discover-logs.sh {project_root} {output_dir}/discovery-logs.json
bash plugins/logs/skills/log-auditor/scripts/discover-vcs-logs.sh {project_root} {output_dir}/discovery-vcs-logs.json
bash plugins/logs/skills/log-auditor/scripts/discover-patterns.sh {output_dir}/discovery-logs.json {output_dir}/discovery-patterns.json
bash plugins/logs/skills/log-auditor/scripts/analyze-storage.sh {output_dir}/discovery-logs.json {output_dir}/discovery-storage.json
```
### Discovery Scripts Purpose:
**discover-logs.sh**:
- Find all log files and log-like files (*.log, *.txt in certain dirs, build outputs)
- Categorize by type: session, build, deployment, debug, test, other
- Record: path, size, last modified, managed/unmanaged status
- Output: JSON inventory of all logs
**discover-vcs-logs.sh**:
- Check which logs are tracked in version control (git)
- Cross-reference with .gitignore
- Identify logs that should be excluded but aren't
- Calculate repository size impact
- Output: JSON list of VCS logs with impact analysis
**discover-patterns.sh**:
- Analyze log file patterns and naming conventions
- Identify common log types (npm-debug.log, jest output, terraform logs)
- Detect log rotation patterns
- Map to fractary-logs categories
- Output: JSON pattern analysis
**analyze-storage.sh**:
- Calculate total storage used by logs
- Break down by category and managed status
- Calculate potential savings from:
- Archival to cloud
- Compression (60-70% reduction)
- Hybrid retention (30 days local)
- Estimate cloud storage costs
- Output: JSON storage analysis
## Step 4: Define the Standard
Define what proper fractary-logs management looks like (the target state):
**Standard Configuration:**
- fractary-logs initialized with config at `.fractary/plugins/logs/config.json`
- fractary-file configured for cloud storage (S3/R2)
- Hybrid retention strategy enabled (30 days local, archived to cloud)
**Standard Directory Structure:**
```
/logs/
├── .archive-index.json # Archive metadata
├── sessions/ # Session logs (*.md)
├── builds/ # Build logs (npm-debug.log, etc.)
├── deployments/ # Deployment logs (terraform.log, etc.)
├── debug/ # Debug logs
└── tests/ # Test output logs
```
**Standard Version Control:**
- All `/logs/` directories excluded in .gitignore
- No log files tracked in Git
- Historical logs removed from Git history (if applicable)
**Standard Archival:**
- Auto-archive enabled on issue close
- Auto-archive enabled for logs older than 30 days
- Compression enabled for logs > 1MB
- Archive index maintained and updated
**Standard Integration:**
- GitHub commenting enabled on archive
- FABER auto-capture enabled (if using FABER)
- Build/deployment logs automatically captured
## Step 5: Analyze Current State vs Standard (Gap Analysis)
Load discovery results and explicitly compare against the standard:
### Configuration Gaps
- **Current**: Check if config exists and is valid
- **Standard**: Config at `.fractary/plugins/logs/config.json` with hybrid retention
- **Gap**: Missing config? Invalid settings? No cloud storage configured?
### Directory Structure Gaps
- **Current**: Where are logs actually located? (from discovery-logs.json)
- **Standard**: All logs in `/logs/{category}/` directories
- **Gap**: Logs scattered across project? Wrong directories? Missing categories?
### Version Control Gaps
- **Current**: Which logs are tracked in Git? (from discovery-vcs-logs.json)
- **Standard**: No logs in version control, all in .gitignore
- **Gap**: X files (Y MB) tracked in Git that should be archived
### Archival Gaps
- **Current**: Is archive index present? Any cloud-archived logs?
- **Standard**: Archive index exists, auto-archive enabled, cloud storage configured
- **Gap**: No archival? Manual archival only? Missing cloud storage?
### Integration Gaps
- **Current**: Are build/deploy logs being captured?
- **Standard**: Auto-capture for all operational logs
- **Gap**: Manual capture only? Logs being ignored?
### Storage Gaps
- **Current**: Total storage, breakdown by location (from discovery-storage.json)
- **Standard**: 80% of logs archived to cloud (compressed), 20% local (recent)
- **Gap**: All local? Wasted repository space? No compression?
**Categorize All Gaps by Priority:**
- **HIGH**: Logs in VCS (security/size risk), no cloud storage config, no .gitignore
- **MEDIUM**: Unmanaged logs, scattered directories, no auto-capture
- **LOW**: Missing categories, optimization opportunities
## Step 6: Generate Standardized Audit Report via docs-manage-audit
Invoke docs-manage-audit skill to create dual-format audit report:
```
Skill(skill="docs-manage-audit")
```
Then provide the audit data:
```
Use the docs-manage-audit skill to create logs audit report with the following parameters:
{
"operation": "create",
"audit_type": "logs",
"check_type": "full",
"audit_data": {
"audit": {
"type": "logs",
"check_type": "full",
"timestamp": "{ISO8601}",
"duration_seconds": {duration},
"auditor": {
"plugin": "fractary-logs",
"skill": "log-auditor"
},
"audit_id": "{timestamp}-logs-audit"
},
"summary": {
"overall_status": "pass|warning|error",
"status_counts": {
"passing": {passing_count},
"warnings": {warning_count},
"failures": {failure_count}
},
"exit_code": {0|1|2},
"compliance_percentage": {compliance_percentage}
},
"findings": {
"categories": [
{
"name": "Configuration",
"status": "pass|warning|error",
"checks_performed": {count},
"passing": {count},
"warnings": {count},
"failures": {count}
},
{
"name": "Structure",
"status": "pass|warning|error",
"checks_performed": {count},
"passing": {count},
"warnings": {count},
"failures": {count}
},
{
"name": "Version Control",
"status": "pass|warning|error",
"checks_performed": {count},
"passing": {count},
"warnings": {count},
"failures": {count}
},
{
"name": "Archival",
"status": "pass|warning|error",
"checks_performed": {count},
"passing": {count},
"warnings": {count},
"failures": {count}
},
{
"name": "Integration",
"status": "pass|warning|error",
"checks_performed": {count},
"passing": {count},
"warnings": {count},
"failures": {count}
},
{
"name": "Storage",
"status": "pass|warning|error",
"checks_performed": {count},
"passing": {count},
"warnings": {count},
"failures": {count}
}
],
"by_severity": {
"high": [
{
"id": "log-001",
"severity": "high",
"category": "version-control",
"message": "X GB of logs tracked in version control",
"details": "Found {count} log files in Git repository",
"remediation": "Exclude logs from Git and archive to cloud"
}
],
"medium": [{finding}],
"low": [{finding}]
}
},
"metrics": {
"total_storage_mb": {total_size_mb},
"managed_logs": {managed_count},
"unmanaged_logs": {unmanaged_count},
"vcs_logs": {vcs_count},
"vcs_impact_mb": {vcs_size_mb}
},
"recommendations": [
{
"priority": "high|medium|low",
"category": "logs",
"recommendation": "{action}",
"impact": "{storage_savings or compliance_improvement}"
}
],
"extensions": {
"logs": {
"total_storage_mb": {total_size_mb},
"potential_savings_mb": {savings_mb},
"cloud_cost_estimate": "{monthly_cost}",
"vcs_impact_mb": {vcs_size_mb},
"implementation_phases": 4
}
}
},
"output_path": "/logs/audits/",
"project_root": "{project-root}"
}
```
This will generate:
- **README.md**: Human-readable audit dashboard
- **audit.json**: Machine-readable audit data
Both files in `/logs/audits/{timestamp}-logs-audit.[md|json]`
**Storage Location**:
- Stored with logs in `/logs/audits/` (ephemeral)
- Subject to same retention as other logs
- Can be archived to cloud with other logs
- Multiple audits create timestamped files (not overwritten)
**Integration**: The docs-manage-audit skill standardizes the audit report format and integrates with logs-manager for retention tracking.
## Step 7: Generate Remediation Specification via Spec Manager
Now create the actionable implementation plan using the Spec Manager agent.
**CRITICAL: This is a separate document from the audit report!**
- **Audit Report** (Step 6): Point-in-time assessment stored with logs (ephemeral)
- Location: `/logs/audits/audit-{timestamp}.md`
- Purpose: Document current state + gaps
- Retention: Subject to log archival policies
- **Remediation Spec** (Step 7): Persistent action plan for project
- Location: `/specs/logs-remediation-{timestamp}.md` (created by Spec Manager)
- Purpose: Actionable implementation plan
- Retention: Committed to version control, kept as project documentation
**If fractary-spec plugin available:**
Invoke the spec-manager agent using natural language to generate the specification:
```
Use the @agent-fractary-spec:spec-manager agent to generate a remediation specification with the following request:

**Important Notes on Spec Manager Invocation:**
- Use natural language agent invocation (not a tool call)
- The spec-manager agent will create timestamped spec in `/specs/`
- Pass all gap analysis findings as requirements
- Include reference to audit report timestamp
- Include executable commands for each task
- Ensure verification steps are specific and testable
**Timestamp Format**: `YYYYMMDD-HHMMSS` (e.g., `20250115-143022`)
**If fractary-spec NOT available:**
Generate markdown specification directly following similar structure but in plain markdown format. Write directly to `/specs/logs-remediation-{timestamp}.md`.
**Note on Spec Location**: The Spec Manager may place the spec in its own managed location. Default is `/specs/` at project root.
