AGENTS.md

inspectrum AGENTS.md is an instructions file for Codex, OpenCode from yannmenec/inspectrum. It costs 2,382 tokens per session, scanned C, original, MIT.

A project instruction guide for inspectrum, an MCP server that asks multiple AI coding tools to review a plan and records the results in Markdown. MCP is a standard way for AI assistants to call external tools.

In plain words
What is it for?
Use it when developing or reviewing inspectrum, especially when running its plan-review tool, building the TypeScript project, or running tests.
Why use it?
It explains the repository's purpose, supported scope, setup, development loop, and testing commands so contributors can work consistently.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions .claude-plugin; mentions CLAUDE.md.

This is yannmenec/inspectrum's own configuration. It tells Codex and OpenCode how to work on inspectrum itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything inspectrum configures →

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 C, and why

inspectrum AGENTS.md scanned grade C with 2 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 1mo 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.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Inspectrum

Universal MCP server for multi-LLM plan review today, plan + code-change review tomorrow. One tool, many reviewers, flat-Markdown session log.

Stack: TypeScript strict (ES2022, Node16 modules), Node ≥ 20, ESM, MCP SDK 1.29+, Zod v4. Distribution: npx inspectrum. License: MIT.

Target user: a solo dev or small team running multiple coding agents (Claude Code, Codex, Cursor, Gemini CLI) who wants to stop copy-pasting plans between them.

What this repo is

  • A single MCP server (src/server.ts) exposing one tool: review_plan.
  • Wraps peer LLM CLIs via child_process (Claude / Codex / Gemini), aggregates their findings, optionally runs a judge agent for consolidation, writes a flat-Markdown session log to ~/.inspectrum/sessions/<ts>__<id>/.
  • v0.1 = plan-only review. v0.2+ extends to code/PR review and more reviewer backends (Kimi, Qwen, Ollama, OpenRouter). Stay inside the current scope unless an ADR or PR explicitly opens a new surface.

Setup & dev loop

  • Install: npm install
  • Build: npm run build (tsc → dist/)
  • Dev: npm run dev (tsx loader, no build step)
  • Tests: npm test (Vitest)
  • Coverage: npm run test:coverage
  • Lint: npx eslint src/ (flat config, eslint.config.js)
  • Typecheck: npx tsc --noEmit
  • Pre-commit (lefthook): typecheck + lint + tests-with-coverage run automatically.

Repo map

  • src/server.ts — MCP entrypoint, stdio transport, registers review_plan.
  • src/schemas.ts — central Zod v4 schemas. All schemas live here, not per module.
  • src/config.ts — ~/.inspectrum/config.toml loader (@iarna/toml + Zod).
  • src/tool/review-plan.ts — orchestration, parallel reviewers, verdict aggregation, report assembly, session write.
  • src/reviewers/ — index.ts (factory) + claude.ts, codex.ts, gemini.ts (CLI wrappers) + health.ts (doctor) + common.ts (shared helpers).
  • src/judge/judge.ts — consolidation pass with validateJudgeInvariants.
  • src/hook/{state,render,plan-gate}.ts — ExitPlanMode plan gate: hash/state loop-protection, budgeted deny rendering, hook orchestration (inspectrum plan-gate; ADR-0002).
  • src/prompts/index.ts — REVIEWER_SYSTEM_PROMPT, JUDGE_SYSTEM_PROMPT as inline TS strings, NOT loaded from .md.
  • src/session/{store,resources}.ts — flat-file persistence + MCP resource exposure.
  • src/version.ts — single source for the package version (server metadata + CLI).
  • .claude-plugin/ + hooks/ + commands/ + scripts/plan-gate-shim.sh — Claude Code plugin; the repo doubles as its marketplace.
  • scripts/e2e-plan-gate.sh — headless plan-mode E2E harness (npm run e2e:gate).
  • tests/{contract,unit,e2e}/ — Vitest. Fixtures under tests/fixtures/. tests/integration/ is opt-in-only (INSPECTRUM_E2E_CODEX=1, real codex smoke — ADR-0002); broader integration remains deferred per ADR-0001.

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.
