review-reliability

review-reliability is a skill for Claude Code, Codex from paultyng/skill-issue. It costs 106 tokens per session (2,093 once invoked), scanned A, original, MIT.

A structured check of software reliability, including how services shut down, communicate over gRPC, and handle failures. gRPC is a way for software services to call one another.

In plain words
What is it for?
Use it to assess a whole codebase, selected packages, or changed files for shutdown problems, missing timeouts, weak failure handling, circuit-breaker issues, and similar reliability risks.
Why use it?
It helps find conditions that could cause outages, stuck requests, or unstable service behavior before production use.

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

review-reliability scanned grade A with 1 finding 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 10d 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.

Reads agent configuration directorieslowAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

- Every finding must cite probed evidence: `path:line`, grep output, or a command result. Pattern-matched suspicion is not evidence. Per `~/.claude/rules/probe-not-assume.md`.

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

The opening of the file, as written. The whole thing — 154 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Reliability Review

A reliability review that produces prioritized findings with code-level references.

Workflow

1. Scope and explore

  • Confirm the scope with the user: full codebase, named packages or directories, changed files only (PR or branch diff), or one named concern.
  • Resolve the scope to a file and package list:
    • Changed files (PR or branch): run git diff --name-only --diff-filter=d <base>...HEAD. The default <base> is main. If the user names a PR number, run gh pr diff <number> --name-only instead. Keep .go files, config files, and Kubernetes manifests. Derive the affected Go packages from the file paths, which are the unique parent directories that contain .go files.
    • Explicit paths or packages: the user can name directories (internal/auth/), Go package patterns (./internal/auth/...), or single files. For a directory or a package pattern, include every file under it.
    • Full codebase: no filter. Explore everything. This is the default.
  • Pass the resolved scope (the file list) to every exploration and investigation subagent, so that findings stay scoped to those files. Reading is not scoped. Follow callees, callers, and third-party source wherever a finding depends on their behavior. Report a bug in code the scope touches or calls even when the bug predates the diff, and prefix it pre-existing:.
  • Explore the scoped code with parallel subagents (subagent_type="explore"). Read the source files, configs, Kubernetes manifests, and deployment definitions.

2. System overview

Produce a short architecture summary of:

  • Services, ports, and transport (gRPC, HTTP)
  • Data stores and external dependencies
  • Deployment model, if you can determine it

Map the critical hot paths:

Client → Transport
  → step 1 (local / I/O annotation)
  → step 2 (DB round-trip #1)
  → step 3 (external call, round-trip #2)
  → response

Annotate each step: local or I/O, serial or parallel, cached or uncached.

1 file 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.

review-reliability is a skill published in the GitHub repository paultyng/skill-issue (8 stars, last pushed 6d ago), licensed MIT. It adds 106 tokens to every session and 2,093 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
