elixir-phoenix-incident-response

elixir-phoenix-incident-response is a skill for Claude Code, Codex from ccarvalho-eng/codex-elixir-phoenix. It costs 27 tokens per session (360 once invoked), scanned A, original, MIT.

A response process for Phoenix production incidents, meaning periods when a live application is unavailable, failing, or degraded. It prioritises restoring service, then narrowing the cause and applying a reversible fix.

In plain words
What is it for?
Use it during outages, error spikes, failed user flows, queue problems, database issues, runtime pressure, or suspected deployment and migration failures.
Why use it?
It gives operators a structured way to assess impact, reduce harm, keep an incident log, and communicate uncertainty. It also requires a rollback path before irreversible changes.

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

elixir-phoenix-incident-response 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 8d 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

Incident Response

Use when production is degraded, error rate spikes, or critical user flows fail.

Primary Goal

Restore service safely first, then deepen diagnosis.

Iron Laws

  1. Stabilization first, optimization second.
  2. Never apply irreversible changes without an explicit rollback option.
  3. Keep a timestamped incident log of actions and outcomes.
  4. One operator executes, one validates when possible.
  5. Communicate status with clear ETAs and unknowns.

Triage Flow

Step 1: Confirm Scope

  • What is broken (endpoint, job queue, LiveView path)?
  • Severity (full outage, partial, degraded)?
  • Start time and suspected trigger (deploy, migration, traffic spike)?

Step 2: Stabilize

Pick the lowest-risk stabilization path:

  • Roll back recent deploy
  • Disable failing feature path
  • Pause problematic jobs/queues
  • Reduce blast radius using feature flags or routing controls

Step 3: Narrow Root Cause

Gather:

  • Error signatures and frequency
  • Recent code/config changes
  • Data-layer symptoms (timeouts, lock contention, deadlocks)
  • Runtime symptoms (process crashes, mailbox growth, scheduler pressure)

Step 4: Hotfix Decision

Ship a hotfix only if:

  • Scope is confirmed
  • Fix is minimal and reversible
  • Validation target is explicit

Output Expectations

Provide:

  • Current severity and impacted surface
  • Stabilization actions taken
  • Most likely root-cause hypotheses
  • Recommended next action (rollback, hotfix, deeper investigation)
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.
