payment-503-spike

payment-503-spike is a skill for Claude Code, Codex from Tommy-yw/RunbookHermes. It costs 0 tokens per session (501 once invoked), scanned A, original, MIT.

A troubleshooting procedure for a payment service returning HTTP 503 errors after a release. HTTP 503 means the server is temporarily unable to handle requests.

In plain words
What is it for?
It helps compare monitoring data, logs, traces, and deployment timing to investigate the incident.
Why use it?
It helps determine whether the release caused database connection-pool exhaustion before recommending a rollback.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

payment-503-spike scanned grade A with 0 findings 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 8d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Payment Service HTTP 503 Spike After Release

Use this skill when payment-service starts returning HTTP 503 shortly after a release, especially after version v2.3.1.

Goal

Find whether the new release caused a database connection pool regression, then propose a safe rollback path.

Evidence to collect

  1. prom_top_anomalies(service="payment-service")
    • Look for http_503_rate, p95 latency, and request volume changes.
  2. loki_query(service="payment-service", query="connection pool exhausted")
    • Look for database pool exhaustion or timeout messages.
  3. trace_search(service="payment-service", error_only=true)
    • Look for slow or failed spans to mysql-payment.
  4. recent_deploys(service="payment-service")
    • Check whether v2.3.1 was deployed shortly before the HTTP 503 increase.
  5. incident_rca_guard(...)
    • Confirm the evidence is consistent before producing the final RCA.
  6. action_policy_guard(...)
    • Generate policy-checked actions.

Decision logic

A release regression is likely when all of these are true:

  • payment-service has a recent deployment such as v2.3.1.
  • HTTP 503 rate increases after the deployment.
  • Logs include connection pool exhausted or similar DB pool messages.
  • Trace evidence points to mysql-payment latency or failed spans.

If the above evidence is present, propose:

  • rollback_canary(service="payment-service", target_revision="v2.3.0", dry_run=true) first.
  • If the operator approves, call rollback_canary(..., dry_run=false, approval_id="...").
  • Then call verify_recovery(service="payment-service").

Safety rules

  • Never execute rollback without approval.
  • Always create a checkpoint before destructive execution.
  • Keep raw logs and full traces out of stable memory.
  • Final answer must cite evidence IDs.

Final answer template

  • Root cause: ...
  • Evidence: ev_metric_http_503_rate, ev_log_pool_exhausted, ev_trace_mysql_latency, ev_deploy_v231
  • Recommended action: rollback from v2.3.1 to v2.3.0 after approval.
  • Verification: check HTTP 503 rate and p95 latency for 10 minutes.

payment-503-spike is a skill published in the GitHub repository Tommy-yw/RunbookHermes (544 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 501 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
