rollback-triggering

rollback-triggering is a skill for Claude Code, Codex from paruff/uFawkesAI. It costs 30 tokens per session (324 once invoked), scanned A, original, MIT.

A testing procedure for deliberately causing a deployment to fail and checking whether the system restores the previous version. A rollback is the return to the last working deployment.

In plain words
What is it for?
Testing invalid configuration files, nonexistent container image versions, failing health checks, or insufficient resources, then validating that rollback occurred.
Why use it?
It reveals whether deployment recovery works before a real failure affects users.

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

rollback-triggering 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 3d 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

Skill: Rollback Triggering

Load trigger: "load rollback-triggering skill" > DORA: Cap 5 (Operational Resilience) Token cost: Low

Purpose

Trigger a controlled deployment failure to test rollback behavior.

Responsibilities

  • Inject invalid manifests
  • Inject failing health checks
  • Validate rollback trigger

Inputs

  • Failure scenario

Outputs

  • rollback-trigger.json

Failure Injection Methods

Method Description
Invalid manifest Deploy manifest with invalid YAML
Wrong image Deploy non-existent image tag
Failing health check Configure failing liveness probe
Resource exhaustion Deploy with insufficient resources

Validation Rules

  • Failure injected successfully
  • Rollback triggered by controller
  • Previous version restored

Output Format

{
  "skill": "rollback-triggering",
  "status": "success",
  "injection_method": "invalid_manifest",
  "rollback_triggered": true,
  "time_s": 30
}

Success Criteria

  • Rollback triggered correctly

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.
