Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00037 | $0.02452 |
| Opus 5 | $0.00018 | $0.01226 |
| Sonnet 5 | $0.00007 | $0.00490 |
| Haiku 4.5 | $0.00004 | $0.00245 |
Grade A, and why
incident-response scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Purpose
Handle production incidents with speed, clarity, and accountability. This skill provides frameworks for on-call response, structured communication, rollback execution, and learning from failures.
Severity Classification
- SEV-1 (Critical): Complete service outage, data loss, or security breach. All hands on deck. Resolve in minutes.
- SEV-2 (Major): Significant degradation affecting most users. Dedicated incident commander. Target resolution under 1 hour.
- SEV-3 (Minor): Partial degradation, workaround available. On-call engineer handles. Target resolution under 4 hours.
- SEV-4 (Low): Cosmetic issues, minor bugs, non-user-facing failures. Handle during business hours.
- Classify based on user impact, not technical complexity. A simple bug affecting all users is higher severity than a complex bug affecting one.
- Escalate severity upward when impact grows. Never downgrade severity during an active incident.
On-Call Runbooks
BAD - Vague runbook:
## Database Issues
If the database is slow, check the connections and maybe restart it.
Contact the DBA if it doesn't work.
GOOD - Actionable runbook with copy-paste commands:
## Runbook: Database Connection Pool Exhausted
### Symptoms
- API returns 503 errors
- Grafana alert: `db_active_connections > 95% of pool_size`
- Logs: "connection pool exhausted, 0 idle connections"
### Diagnose (< 1 minute)
kubectl exec -it deploy/api -- curl localhost:8080/debug/db
# Shows: active=100, idle=0, max=100, waiting=47
psql -h $DB_HOST -c "SELECT count(*) FROM pg_stat_activity WHERE state='active';"
### Fix (choose one)
1. **Kill idle transactions** (safest):
psql -h $DB_HOST -c "SELECT pg_terminate_backend(pid) FROM pg_stat_activity WHERE state='idle in transaction' AND query_start < now() - interval '5 min';"
2. **Increase pool size** (temporary):
kubectl set env deploy/api DB_POOL_SIZE=200
kubectl rollout restart deploy/api
3. **Rollback last deploy** (if caused by new code):
kubectl rollout undo deploy/api
### Do NOT
- Do NOT restart the database. Active transactions will be lost.
- Do NOT increase pool size above 200 without DBA approval.
### Escalation
- Slack: #team-platform | PagerDuty: Platform On-Call
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

incident-response is a skill published in the GitHub repository medy-gribkov/arcana (1 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 37 tokens to every session and 2,452 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
