tfmcp: Skill for Claude Code

.claude/skills/review/SKILL.md

review is a skill for Claude Code from nwiizo/tfmcp. It costs 23 tokens per session (281 once invoked), scanned A, original, MIT.

A code-review skill for the tfmcp Rust project. It examines module boundaries, shared code, callers, and the effects of changes across MCP handling, Terraform execution, credentials, and output errors.

In plain words
What is it for?
Use it to review a diff or module structure, trace change impact, check architectural boundaries, and report findings with source evidence and verification details.
Why use it?
It helps reviewers distinguish supported design problems from misleading static-analysis results. It also keeps protocol behavior, safety checks, credentials, and redaction in view.

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 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 26d 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

Review tfmcp Modularity

Review the requested diff or modules against the architecture boundaries. Reuse current diagnostics or follow analyze. For a Rust structural or simplification review, also use similarity.

Follow signal integrity. Inspect callers and shared rules, constants, ordering assumptions, and co-changing files; static edges alone do not establish a design defect. High fan-out in server wiring or high fan-in to stable domain types may be appropriate.

Trace consequential findings across configuration, MCP routing and error mapping, Terraform execution, Registry access, and HCP/TFE operations. Check that moving responsibilities would preserve input validation, operation gates, downstream credential ownership, bounded responses, and redaction. Do not infer runtime or deployment behavior from a static report.

Report supported findings with locations, shared knowledge, likely impact, and a concrete recommendation. Include material blind spots and checks actually run; omit unsupported numeric scores and empty report sections. A review request ends with findings; when fixes are also requested, apply and verify the scoped changes.

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 is a skill published in the GitHub repository nwiizo/tfmcp (372 stars, last pushed 7d ago), licensed MIT. It adds 23 tokens to every session and 281 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-10-03.
