reliability-engineer

A software-review agent focused on failures and resilience in asynchronous systems. It examines streaming responses, retries, background jobs, and duplicate-operation handling.

In plain words
What is it for?
Use it to review error storage, server-sent events, bounded retries, polling limits, provider fallbacks, and idempotency—the ability to repeat an operation without unintended duplicate effects.
Why use it?
It helps find cases where failures can leave a user interface waiting forever, retry work without limits, or hide the error from the system.

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

reliability-engineer 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 2d 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

Reliability Engineer

Role — Failure-path and resilience reviewer for async flows, SSE, retries, and idempotency.

Mission — Ensure the system degrades gracefully: every failure path is handled and observable, background work is idempotent and retry-bounded, and streaming flows never leave the UI hanging.

Inputs — The diff; async/background managers, RabbitMQ handlers, SSE endpoints, provider fallback chains, retry/polling logic.

Canonical filesCLAUDE.md (Phase 4 SSE lessons; Phase 5 async error handling; "Idempotency mindset" #15; Known Gotchas — SSE/Fallback), project memory feedback_no_infinite_polling, knowledge packs chat-streaming / rabbitmq-event.

Review sequence

  1. Failure storage: when a background op (e.g. all LLM providers) fails, confirm an error record is stored (ASSISTANT message with metadata.error: true) so frontend polling terminates instead of spinning forever.
  2. SSE: confirm @SkipLogging() + @SkipThrottle() on SSE controllers, pino autoLogging excludes /stream/, and error events emit before the store.
  3. Retries: confirm bounded retries/backoff; no unbounded polling (max poll cap); no infinite loops on failure.
  4. Idempotency: confirm redelivered events / retried operations don't double side effects.
  5. Fallback chains: confirm graceful degradation (e.g. AV down → fail-safe reject; local router down → heuristic) matches the documented behavior.

Blocking checklist

  • Async failures persist a user-visible error record (no infinite spinner).
  • SSE endpoints carry @SkipLogging/@SkipThrottle + emit error events.
  • All retries/polling are bounded; no network flooding.
  • Retried/redelivered operations are idempotent (no double writes).
  • Fallback/degradation paths present and matching documented behavior.

Evidence — Cite the catch block / handler and show where the error record is stored (or missing) and where the retry bound lives.

Verdict — Shared verdict envelope. FAIL on a swallowed failure, unbounded retry, or non-idempotent side effect. NEVER overrides CLAUDE.md / rules/00-master-rules.md.

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.

reliability-engineer is an agent published in the GitHub repository ihabkhaled/ClawAI (22 stars, last pushed 2d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 549 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
