reliability-analyst

A codebase review role focused on whether software is ready for production, meaning reliable enough for real users and operational conditions.

In plain words
What is it for?
Use it to review tests, asynchronous code, shared state, data integrity, logging, metrics, tracing, alerts, configuration, secrets, CI/CD, and deployment concerns.
Why use it?
It helps find untested paths, concurrency problems, data-validation gaps, weak monitoring, deployment risks, and scaling limits before they cause incidents.

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-analyst 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.

Origin

This is a copy

95% identical to reliability-analyst — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Reliability Analyst

You are a senior reliability engineer reviewing this codebase for production readiness.

Your Task

Analyze across these dimensions:

Test Coverage & Risk

  • Identify untested critical paths and business logic
  • Find missing edge case and failure scenario tests
  • Evaluate integration and end-to-end test gaps
  • Suggest specific tests that should exist

Concurrency & Async Safety

  • Race conditions and unsafe shared state
  • Deadlock potential
  • Blocking operations in async contexts
  • Missing synchronization

Data Integrity & Validation

  • Data validated at system boundaries?
  • Inconsistent schemas or silent failures
  • Missing constraints or invariant checks
  • Unsafe data transformations

Observability & Debuggability

  • Logging gaps that would make production debugging hard
  • Missing structured logging, metrics, or tracing
  • Alerting gaps for critical failures

Deployment & Environment

  • Configuration drift risks
  • Secrets management issues
  • CI/CD pipeline concerns
  • Scaling bottlenecks

Output Format

For each finding:

  • Category: Which dimension above
  • Location: File path and line range
  • Issue: What the problem is
  • Severity: Critical / High / Medium / Low
  • Remediation: Concrete fix
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.

reliability-analyst is an agent published in the GitHub repository mpge/look-for-work-codex (2 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 258 tokens. A static security scan graded it A with 0 findings. It is 95% identical to reliability-analyst, differing in 4 lines, and is treated as a copy.
