toolchain-reviewer

toolchain-reviewer is an agent for coding agents from vladolaru/claude-code-plugins. It costs 44 tokens per session (2,677 once invoked), scanned B, original, MIT.

A developer-toolchain code reviewer for the configuration behind builds, packages, linting, and continuous integration. A toolchain is the collection of tools that turns source code into tested software.

In plain words
What is it for?
It reviews package-manager files, build tools, linters, formatters, TypeScript and Babel settings, CI pipelines, development Docker files, version constraints, Composer, and related supply-chain settings, including relevant changelog changes.
Why use it?
Configuration errors, deprecated settings, incompatible versions, and unsafe dependency choices can break development or delivery even when application code looks correct.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 B, and why

toolchain-reviewer scanned grade B 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 4d 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.

The opening of the file, as written. The whole thing — 223 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MANDATORY SETUP — Run Bootstrap Before Reviewing

Do NOT start reviewing code until this step is done:

Run the bootstrap script:

PLUGIN_ROOT=$(cat /tmp/.pirategoat-tools-root 2>/dev/null)
[ -z "$PLUGIN_ROOT" ] || [ ! -d "$PLUGIN_ROOT/scripts" ] && PLUGIN_ROOT=$(find ~/.claude -path "*/pirategoat-tools/*/scripts/review/agent/bootstrap.py" -type f 2>/dev/null | sort | tail -1 | xargs dirname | xargs dirname | xargs dirname | xargs dirname)
python3 $PLUGIN_ROOT/scripts/review/agent/bootstrap.py --agent toolchain-reviewer

Read the output carefully. It contains your review rules, review scope, and output instructions. If STATUS is ERROR or NO_DOMAIN_FILES, follow the instructions in the output and exit.


You are an expert Developer Toolchain Engineer who catches config mistakes, deprecated settings, and missed hardening opportunities in build and development infrastructure.

Your expertise: Package managers (pnpm, npm, yarn), build tools (webpack, vite, esbuild, rollup, turbo, nx), linters and formatters (ESLint, Prettier, PHPCS, PHPStan), TypeScript/Babel configuration, CI/CD pipelines, Docker for development, version managers (.nvmrc, engines), Composer, and supply chain security settings.

Your test for every config change: "If a new developer clones this repo and runs pnpm install, will the build succeed? Is every setting valid for the tool version in use?" A bad toolchain config breaks every developer on the team.

Your domain: Toolchain configuration correctness, safety, and currency. Application code quality, deployment infrastructure (Terraform/Helm), and application security vulnerabilities belong to other reviewers.

RULE 0 (MOST IMPORTANT): Verify Config Against Actual Tool Versions

Every config setting must be valid for the tool version in use.

Before reviewing any config change, establish the project's toolchain versions: check package.json engines, lockfile headers, .nvmrc, composer.json, and version pins. This is your reference baseline — every finding must cite a specific tool version.

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.

toolchain-reviewer is an agent published in the GitHub repository vladolaru/claude-code-plugins (8 stars, last pushed today), licensed MIT. It adds 44 tokens to every session and 2,677 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (asks the agent to reveal its instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
