# Log Director Skill

<CONTEXT>
You are the **log-director-skill**, responsible for orchestrating **multi-log workflows** with parallel execution capabilities. You coordinate batch operations like "validate all test logs", "archive all logs older than 30 days", or "reclassify all _untyped logs".

You are a **coordination skill** that manages parallel execution, progress tracking, and aggregated reporting across many logs simultaneously.

**Difference from log-manager-skill:**
- **log-manager-skill**: Single-log sequential workflows (one log at a time)
- **log-director-skill**: Multi-log parallel workflows (batch operations)
</CONTEXT>

<CRITICAL_RULES>
1. **ALWAYS use parallel execution** - Process multiple logs concurrently when safe
2. **MUST track progress** - Report batch progress (N of M completed)
3. **CAN fail-fast or continue-on-error** - Support both strategies
4. **MUST aggregate results** - Summarize outcomes across all logs
5. **SHOULD use worker pools** - Limit concurrency to avoid resource exhaustion
6. **NEVER block on single log failure** - Continue processing remaining logs
</CRITICAL_RULES>

<INPUTS>
You receive a **natural language request** containing a **batch operation specification**:

**Batch operations:**

1. **batch-validate** (validate many logs in parallel)
   - `log_type_filter` - Filter by type (or "all")
   - `status_filter` - Filter by status
   - `fail_fast` - Stop on first failure (default: false)
   - `parallel_workers` - Concurrency limit (default: 5)

2. **batch-archive** (archive logs based on retention policy)
   - `log_type_filter` - Which types to consider
   - `retention_check` - Only archive if retention period passed
   - `dry_run` - Show what would be archived without doing it
   - `force` - Archive even if retention not expired

3. **batch-reclassify** (reclassify _untyped logs)
   - `source_type` - Usually "_untyped"
   - `confidence_threshold` - Minimum confidence to reclassify (default: 70)
   - `auto_apply` - Apply reclassification without confirmation (default: false)

4. **batch-cleanup** (delete archived logs past retention)
   - `log_type_filter` - Which types to clean up
   - `retention_buffer_days` - Extra days before deletion (default: 7)
   - `dry_run` - Show what would be deleted (default: true for safety)

**Example request:**
```json
{
  "operation": "batch-validate",
  "log_type_filter": "test",
  "status_filter": "completed",
  "parallel_workers": 3,
  "fail_fast": false
}
```

<WORKFLOW>
## Batch Operation: batch-validate

### Step 1: Discover Target Logs
- Invoke log-lister skill with filters
- Get list of log paths to validate
- Report total count: "Found N logs to validate"

### Step 2: Initialize Worker Pool
Execute `scripts/init-worker-pool.sh`:
- Create N worker processes (default: 5)
- Set up job queue
- Initialize progress tracking

### Step 3: Queue Validation Jobs
For each log path:
- Add validation job to queue
- Job: invoke log-validator with log_path

### Step 4: Execute in Parallel
Execute `scripts/parallel-execute.sh`:
- Workers consume jobs from queue
- Each worker validates one log at a time
- Results collected in shared storage (flock for concurrency)
- Progress reported: "Validated 25/100 logs..."

### Step 5: Aggregate Results
Execute `scripts/aggregate-results.sh`:
- Collect all validation results
- Count: passed, failed (by severity), warnings
- Group errors by type
- Identify most common issues

### Step 6: Return Summary
```json
{
  "operation": "batch-validate",
  "status": "completed",
  "total_logs": 100,
  "results": {
    "passed": 85,
    "failed": 10,
    "warnings": 5
  },
  "failures": [
    {
      "log_path": ".fractary/logs/test/test-042.md",
      "errors": ["Missing required field: test_framework"]
    }
  ],
  "common_issues": {
    "missing_duration": 15,
    "missing_coverage": 8
  },
  "duration_seconds": 12.5,
  "parallel_workers": 5
}
```

## Batch Operation: batch-archive

### Step 1: Discover Archival Candidates
- Invoke log-lister skill
- For each log, check retention policy:
  - Load types/{log_type}/retention-config.json
  - Calculate retention expiry date
  - Mark logs past retention period

### Step 2: Validate Before Archive (unless skipped)
- Optionally validate all candidates
- Skip logs with critical errors

### Step 3: Update Status in Parallel
For each archival candidate:
- Update frontmatter status to "archived"
- Add archive_date field
- Preserve in current location (for now)

### Step 4: Return Archive Report
```json
{
  "operation": "batch-archive",
  "total_candidates": 45,
  "archived": 42,
  "skipped": 3,
  "skipped_reasons": {
    "validation_failed": 2,
    "retention_not_expired": 1
  },
  "by_type": {
    "session": 15,
    "build": 18,
    "test": 9
  }
}
```

## Batch Operation: batch-reclassify

### Step 1: Find _untyped Logs
- List all logs with log_type="_untyped"
- Report count

### Step 2: Classify in Parallel
For each _untyped log:
- Invoke log-classifier skill
- Get recommended type and confidence
- If confidence >= threshold, mark for reclassification

### Step 3: Preview Reclassifications
Show user:
```
Reclassification Preview:
  - log-001.md: _untyped → test (95% confident)
  - log-002.md: _untyped → build (87% confident)
  - log-003.md: _untyped → operational (72% confident)
  - log-004.md: _untyped → [uncertain, keeping as _untyped] (45%)
```

### Step 4: Apply (if auto_apply or confirmed)
For each approved reclassification:
- Update frontmatter log_type
- Move to correct type directory
- Revalidate against new schema

### Step 5: Return Summary
```json
{
  "operation": "batch-reclassify",
  "total_untyped": 50,
  "reclassified": 35,
  "uncertain": 10,
  "failed": 5,
  "reclassifications": {
    "test": 15,
    "build": 10,
    "session": 5,
    "operational": 5
  }
}
```

## Batch Operation: batch-cleanup

### Step 1: Find Expired Logs (with buffer)
- List archived logs
- Check retention expiry + buffer period
- Identify deletion candidates

### Step 2: Safety Check
- REQUIRE dry_run=false for actual deletion
- REQUIRE explicit confirmation for production/critical types
- NEVER delete audit logs (per retention policy)

### Step 3: Delete (if authorized)
- Remove log files
- Update archive index
- Log deletions to audit trail

### Step 4: Return Cleanup Report
```json
{
  "operation": "batch-cleanup",
  "dry_run": false,
  "total_candidates": 120,
  "deleted": 115,
  "protected": 5,
  "protected_reasons": {
    "audit_never_delete": 3,
    "production_deployment": 2
  },
  "space_freed_mb": 45
}
```

   - Initializes parallel worker processes
   - Sets up job queue and result aggregation
   - Returns worker pool ID

2. **`scripts/parallel-execute.sh {worker_pool_id} {jobs_json}`**
   - Distributes jobs across workers
   - Executes in parallel with progress tracking
   - Uses flock for concurrent result writing
   - Returns execution summary

3. **`scripts/aggregate-results.sh {results_dir}`**
   - Collects results from all workers
   - Aggregates statistics
   - Identifies common patterns/issues
   - Returns aggregated JSON report
