A workflow for managing security alerts by searching them first, then acknowledging, resolving, or temporarily suppressing them.

In plain words
What is it for?
Use it to update alert status, record reasons for decisions, and reduce narrowly defined repetitive noise.
Why use it?
It prevents alert queues from becoming confusing or overloaded with duplicate or expected warnings.

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

security-alert-hygiene 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 9d 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.

What it actually says

Security Alert Hygiene

Use this when the main job is to manage alert state cleanly: acknowledge, resolve, suppress, or reduce duplicate noise.

Workflow

  1. Search first with security_alert_search.
  2. Narrow by source, type, and evidence pattern before mutating state.
  3. Choose the correct disposition:
    • security_alert_ack for understood alerts that should remain visible
    • security_alert_resolve for investigated alerts that are closed
    • security_alert_suppress for expected repetitive noise with an expiry
  4. Always record the operator reason when resolving or suppressing.

Decision Rules

  • Use acknowledge when the alert is real and still relevant.
  • Use resolve when the condition has been investigated and closed.
  • Use suppress when the alert is expected to recur and would otherwise overwhelm the queue.
  • Prefer suppressing one narrow pattern over broad source-wide suppression.

Boundaries

  • Use host-firewall-defense or native-av-management if the first problem is understanding whether the alert is meaningful.
  • Use security-triage if multiple alert families suggest a broader incident.

Gotchas

  • Do not suppress without an expiry unless there is a compelling operational reason.
  • Do not resolve an alert just because it is noisy.
  • Do not mutate alert state from a vague natural-language description when the exact alert id or narrow pattern can be found first.
Files

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.

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.
