triage-security-incident

triage-security-incident is a skill for Claude Code, Codex from gaelic-ghost/socket. It costs 50 tokens per session (441 once invoked), scanned A, original, Apache-2.0.

A guide for investigating a suspected security incident across devices, accounts, applications, cloud systems, networks, or data. It helps establish what happened, how urgent it is, what may be affected, and who makes decisions.

In plain words
What is it for?
Use it for alerts, suspected compromise, unauthorized access, malware, credential concerns, data exposure, fraud, disruption, or ongoing attacks.
Why use it?
It supports early decisions without confusing confirmed observations with guesses or destroying evidence through premature cleanup.

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

triage-security-incident 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 yesterday.

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.

Triage Security Incident

Overview

Establish whether coordinated response is needed, what may be affected, and who owns decisions. Preserve uncertainty and avoid destructive cleanup while urgent harm reduction and evidence collection are balanced.

Read references/incident-triage-record.md for the initial record aligned with current NIST incident-response guidance.

Workflow

  1. Open the incident record.
    • Record reporter, detection source, time/timezone, symptoms, affected person/system, current status, and incident lead.
  2. Validate the signal.
    • Preserve the original alert/report and confirm artifact, account, host, service, or event identity.
    • Separate direct observation, external intelligence, automation labels, and speculation.
  3. Estimate scope and urgency.
    • Identify potentially affected assets, identities, data, users, environments, business function, privileges, and time window.
    • Record ongoing execution, access, exfiltration, destruction, fraud, safety, or service impact.
  4. Decide immediate harm reduction.
    • Choose reversible isolation, session/token revocation, feature disablement, traffic control, or monitoring only when evidence and authority justify it.
    • State evidence loss and operational impact.
  5. Preserve priority evidence.
    • Capture volatile state, logs, artifacts, identity/provider records, application events, network evidence, and timeline sources proportionately.
  6. Establish coordination.
    • Name technical, business, legal/privacy, communications, vendor/provider, and affected-user contacts as applicable; keep sensitive details need-to-know.
  7. Route the next phase.
    • Use containment for ongoing harm, hunting for scope, specialist analysis for evidence, and recovery only after eradication criteria are defined.

Output

Return incident identity/owner, signal confidence, affected/potential scope, urgency, immediate actions, evidence plan, contacts, open questions, and next phase.

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.
