recover-security-incident

recover-security-incident is a skill for Claude Code, Codex from gaelic-ghost/socket. It costs 51 tokens per session (407 once invoked), scanned A, original, Apache-2.0.

A recovery guide for removing an attacker’s access and returning affected systems to a trusted state. It covers rebuilding or repairing systems, rotating secrets, staged restoration, and validation.

In plain words
What is it for?
Use it after incidents affecting hosts, accounts, applications, cloud resources, networks, or data.
Why use it?
It provides a controlled way to restore service without leaving behind persistence, compromised credentials, weak settings, or unverified risks.

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

recover-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.

What it actually says

Recover Security Incident

Overview

Return systems and people to a trusted operating state using explicit eradication and validation criteria. Recovery is complete only when restored behavior, security controls, access, monitoring, and residual risk are verified.

Read references/recovery-gates.md for staged return-to-service gates.

Workflow

  1. Establish eradication criteria.
    • Identify root/access path, persistence, affected identities/secrets, vulnerable configuration/code, related artifacts, and known scope.
  2. Choose restore basis.
    • Decide clean rebuild, known-good backup, patched image, repaired configuration, provider recovery, or controlled cleanup from evidence and integrity confidence.
  3. Eradicate.
    • Remove verified mechanisms, patch or mitigate the entry path, rotate/revoke secrets and sessions from trusted systems, repair policies/configuration, and preserve evidence of changes.
  4. Restore in stages.
    • Validate offline or isolated, restore dependencies/data, enable limited traffic/users, monitor, then broaden service.
  5. Verify security and function.
    • Reproduce the original detection/path as a negative test, confirm expected functionality, review access/persistence/network/logging, and check backups and monitoring.
  6. Remove temporary controls deliberately.
    • Inventory emergency rules, disabled services, isolation, temporary accounts, logging, tokens, and exceptions; retain only approved controls with owners/expiry.
  7. Close and improve.
    • Record timeline, root cause, affected scope, actions, notifications, evidence retention, lessons, structural hardening, and residual risk owner.

Output

Return eradication evidence, restore basis, staged recovery results, negative retest, temporary-control disposition, monitoring window, lessons/actions, and residual-risk decision.

Files

What ships with it

2 files 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.
