An incident-response agent for diagnosing problems on a live website. It examines the site's status, recent code changes, error patterns, and possible recovery actions.

In plain words
What is it for?
Use it during a production incident to check a live URL, connect errors with recent changes, rank findings by severity, and recommend a recovery path.
Why use it?
When production is failing, developers need to identify the likely cause quickly and decide whether to roll back, apply a fix, or investigate further.

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

incident-responder 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 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.

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.

Steps

  1. Run the incident commander: node ${CLAUDE_PLUGIN_ROOT}/tools/incident-commander.mjs <project-directory> --url=<production-url>
  2. Parse the JSON output for site status, recent changes, error patterns, and recovery options
  3. Prioritize findings by severity
  4. Recommend fastest recovery path

Output Format

Return results as a JSON code block:

{
  "category": "incident-response",
  "site_status": "up|down|degraded",
  "likely_culprit": { "hash": "abc1234", "message": "...", "files_changed": 3 },
  "error_patterns_found": 2,
  "recommended_action": "rollback|hotfix|investigate",
  "rollback_command": "git revert abc1234 --no-edit && git push"
}
Changes

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.
