Skill: charlie-morrison/ops-incident-postmortem (version 1.0.0)

--- name: incident-postmortem description: Generate structured, blame-free incident postmortem reports from logs, timeline data, and incident metadata. Produces root cause analysis, impact assessment, timeline reconstruction, lessons learned, and action items. Supports log parsing (syslog, JSON, Apache/Nginx, Python tracebacks), timeline JSON input, blame-free language checking, and multiple output formats (markdown, HTML, JSON). Use when asked to create a postmortem, write an incident report, document an outage, generate a post-incident review, analyze incident timeline, check postmortem language for blame, create RCA (root cause analysis), or produce an after-action report. Triggers on "postmortem", "incident report", "outage report", "post-incident", "root cause analysis", "RCA", "after-action", "blameless review", "incident review". --- # Incident Postmortem Generate structured, blame-free incident postmortem reports with timeline reconstruction, log analysis, and action item tracking. ## Quick Start ```bash # Create a postmortem from scratch (fills in template sections) python3 scripts/generate_postmortem.py --title "Database outage" --severity P1 # Parse logs to auto-extract timeline events python3 scripts/generate_postmortem.py --title "API latency" --log /var/log/app.log --since 2h # Load a complete incident from JSON python3 scripts/generate_postmortem.py --from incident.json --output html -o postmortem.html # Combine logs + manual timeline python3 scripts/generate_postmortem.py --title "Deploy failure" --log /var/log/deploy.log --timeline events.json # Check existing document for blameful language python3 scripts/generate_postmortem.py --check-blame existing-report.md ``` ## Features 1. **Log parsing** — Auto-detects syslog, JSON, Apache/Nginx, Python tracebacks, Docker, generic timestamped formats. Extracts errors, warnings, and notable events into a timeline. 2. **Timeline reconstruction** — Merges log-extracted events with manual timeline JSON. Sorted chronologically with event type labels (detection, action, escalation, resolution). 3. **Blame-free language** — Built-in checker scans for blameful patterns and suggests alternatives. Use `--check-blame` on any document. 4. **Severity classification** — P0 (critical) through P3 (low) with appropriate descriptions. 5. **Multiple outputs** — Markdown (default), HTML (styled), JSON (structured). 6. **CI-friendly exit codes** — 0 (clean), 1 (errors found), 2 (critical severity). 7. **Template sections** — Summary, impact, timeline, root cause, detection, resolution, lessons learned, action items. ## Options | Flag | Default | Description | |------|---------|-------------| | `--title` | required | Incident title | | `--severity` | P2 | P0, P1, P2, or P3 | | `--date` | today | Incident date | | `--duration` | TBD | How long it lasted | | `--summary` | — | Brief summary text | | `--log` | — | Log file path (repeatable) | | `--since` | all | Time filter for logs (1h, 24h, 7d) | | `--timeline` | — | Timeline JSON file | | `--from` | — | Load full incident from JSON | | `--output` | markdown | Output format: markdown, html, json | | `-o` | stdout | Output file path | | `--check-blame` | — | Check file for blameful language | ## Workflow ### After an Incident 1. Gather logs: `--log /var/log/app.log --log /var/log/nginx/error.log --since 4h` 2. Generate draft: `python3 scripts/generate_postmortem.py --title "..." --severity P1 --log ... -o draft.md` 3. Fill in template sections (summary, root cause, impact, resolution) 4. Run blame check: `--check-blame draft.md` 5. Add action items and share ### From Structured Data 1. Create `incident.json` with full details (see `references/templates.md` for schema) 2. Generate: `--from incident.json --output html -o postmortem.html` ### Periodic Review Use JSON output to track action item completion across multiple postmortems. ## References - **templates.md** — Full JSON schema, timeline event types, blame-free language guide with replacements

path: STATUS.md
content: # incident-postmortem — Status

**Status:** Ready
**Price:** $59
**Built:** 2026-03-30

## Tested
- Basic generation (--title --severity)
- Full JSON incident file (--from)
- Log parsing with event extraction
- HTML output with styled template
- JSON structured output
- Blame language checker
- Multiple log formats

## Next Steps
- Publish to ClawHub after April 10


path: log.md
content: # incident-postmortem — Log

## 2026-03-30

### Done
- Built complete incident postmortem generator
- Script: `scripts/generate_postmortem.py` (~450 lines Python stdlib)
- Reference: `references/templates.md` — JSON schema, event types, blame-free guide
- Features: log parsing (8 formats), timeline merge, blame checker, P0-P3 severity, 3 output formats
- 18 error indicator patterns for event classification
- 4 blameful language patterns with suggestions
- Tested: basic generation, full JSON, log parsing, HTML/JSON output, blame checker
- Packaged to `dist/incident-postmortem.skill` ✅

### Decisions
- $59 pricing — mid-range, accessible for engineering teams

## Incident JSON Schema

Use `--from incident.json` to load a complete incident definition:

```json
{
  "title": "Database connection pool exhaustion",
  "severity": "P1",
  "date": "2026-03-28",
  "duration": "45 minutes",
  "status": "Resolved",
  "author": "oncall-team",
  "summary": "Primary database became unresponsive due to connection pool exhaustion caused by a leaked connection in the new payment service.",
  "impact": "All API requests returned 503 for 45 minutes. ~12,000 users affected. Estimated revenue impact: $8,500.",
  "root_cause": "The payment service v2.3.1 deployed at 14:20 introduced a code path that opened database connections without closing them on error. Under load, this exhausted the 100-connection pool within 15 minutes.",
  "detection": "PagerDuty alert fired at 14:35 when API error rate exceeded 50% threshold. Time to detect: 15 minutes.",
  "resolution": "1. Rolled back payment service to v2.3.0 at 14:50\n2. Manually cleared stale connections\n3. Database recovered at 15:05",
  "timeline": [
    {"time": "2026-03-28T14:20:00", "event": "Payment service v2.3.1 deployed", "type": "action"},
    {"time": "2026-03-28T14:35:00", "event": "API error rate alert fired", "type": "detection"},
    {"time": "2026-03-28T14:38:00", "event": "Oncall engineer acknowledged", "type": "action"},

    {"time": "2026-03-28T15:05:00", "event": "All services recovered", "type": "resolution"}
  ],
  "lessons_learned": [
    "Connection pool monitoring was not alerting on utilization, only on total failures",
    "Rollback process took 12 minutes — should be automated",
    "The leak was caught in code review but not flagged as blocking"
  ],
  "action_items": [
    {"action": "Add connection pool utilization alerts at 80% threshold", "owner": "Platform", "priority": "P1", "due": "2026-04-05", "status": "Open"},
    {"action": "Implement automated rollback on error rate spike", "owner": "SRE", "priority": "P1", "due": "2026-04-15", "status": "Open"},
    {"action": "Add integration test for connection cleanup on error paths", "owner": "Payments", "priority": "P2", "due": "2026-04-10", "status": "Open"}
  ]
}
```

## Timeline Event Types

| Type | Meaning | Example |
|------|---------|---------|
| `action` | Something someone did | "Deployed v2.3.1", "Restarted service" |
| `detection` | Issue was noticed | "Alert fired", "Customer reported" |
| `escalation` | Escalated to another team | "Paged database oncall" |
| `communication` | Status update sent | "Posted to #incidents", "Updated status page" |
| `resolution` | Issue resolved | "Service recovered", "Fix deployed" |

## Blame-Free Language Guide

### Principles

1. **Describe system conditions, not human failings** — "The monitoring gap allowed..." not "The engineer failed to..."
2. **Use passive voice for errors** — "The config was deployed without validation" not "They deployed without validating"
3. **Focus on process gaps** — "The review process did not catch..." not "The reviewer missed..."
4. **Assume competence** — People made the best decisions with the information available at the time

### Replacements

| Blameful | Blame-free |
|----------|-----------|
| "Engineer X caused the outage" | "The deployment triggered a failure in..." |
| "Human error" | "A process gap allowed..." |
| "Should have known" | "The system did not surface..." |
| "Failed to check" | "The check was not part of the process" |
| "Careless mistake" | "The existing safeguards did not prevent..." |
| "Forgot to" | "The runbook did not include..." |

### Use `--check-blame` to scan existing documents:

```bash
python3 scripts/generate_postmortem.py --check-blame existing-postmortem.md
```


path: scripts/generate_postmortem.py
content: #!/usr/bin/env python3
"""Generate structured incident postmortem reports.
