resource-review

resource-review is a skill for Claude Code, Codex from photostructure/coding-skills. It costs 157 tokens per session (3,379 once invoked), scanned A, original, MIT.

A code-review skill for finding provable memory and resource-safety defects in modern C and C++ code, including Node.js native add-ons. It checks how objects and resources are created, used, and released.

In plain words
What is it for?
Use it to review C/C++ code, investigate segmentation faults and memory leaks, and check native Node.js add-ons for concrete lifetime, ownership, and concurrency errors.
Why use it?
It helps identify real causes of leaks, crashes, use-after-free errors, double frees, buffer overflows, and data races without treating every missing safety setting as a bug.

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

resource-review 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 5d 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.

C/C++ Resource & Memory Review

Leaf-mode guard

If the task identifies your role as leaf-reviewer or sets delegation-budget: 0, read and follow references/validation-pass.md, validate only the supplied candidates, return the verdicts to the caller, and stop before the full workflow below.

Identify provable memory- and resource-safety defects in modern C/C++ (C++17), including Node.js native addons built with node-gyp and node-addon-api. Reason about object lifetimes and resource ownership the way an AddressSanitizer report would — then report only what you can back with concrete proof. Signal over noise.

This skill finds defects (a leak, a use-after-free, a race that actually exists). For "is this project set up with the right hardening flags, sanitizers, CI, and conventions?" use the project-setup skill, which assesses preventive controls, not exploitable bugs. A missing hardening flag is not a defect; a heap-buffer-overflow is.

Scope

In scope: C and C++ translation units (.c/.cc/.cpp/.cxx/.h/.hpp), especially Node.js native addons (Napi::ObjectWrap, AsyncWorker, ThreadSafeFunction, finalizers), the C ABI boundary between C++ and C libraries, and the binding.gyp defines that change runtime behavior.

Out of scope: the surrounding JavaScript/TypeScript (defer to the web-security-review skill), and pure build-hardening/convention gaps (defer to the project-setup skill).

Report vs. research — the prime directive

  • Report on: only the file, diff, or path the user asked about.
  • Research: the entire module to establish the facts — who allocates, who frees, which thread touches what, when a destructor or finalizer actually runs, and what the C library's ownership contract says.

A native defect is almost never visible in one function. Trace the allocation to its free, the handle to its close, the pointer to the object's real lifetime, and the napi_value to the call that created it. Never report on pattern-match alone.

What ships with it

8 files 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.

resource-review is a skill published in the GitHub repository photostructure/coding-skills (3 stars, last pushed yesterday), licensed MIT. It adds 157 tokens to every session and 3,379 once invoked, about $0.0008 per session on Opus 5. 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 2026-08-31.
