reviews: Instructions file for Codex

AGENTS.md

reviews AGENTS.md is an instructions file for Codex, OpenCode from figitaki/reviews. It costs 1,637 tokens per session, scanned A, original, MIT.

Project-specific instructions for Reviews, a tool that lets developers inspect arbitrary code differences, not only changes in GitHub pull requests. They describe its Phoenix web app, Rust command-line tool, database, tests, and local review workflow.

In plain words
What is it for?
Use them to run the development server, execute tests and formatting checks, compile the project, and push a branch's changes into a local review page.
Why use it?
They reduce setup mistakes when working in this repository, such as starting a second development server or skipping required checks. They also explain how to publish a local difference for browser-based review.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions Claude Code; mentions Codex.

This is figitaki/reviews's own configuration. It tells Codex and OpenCode how to work on reviews 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 reviews 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 A, and why

reviews AGENTS.md 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 20d 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.

How it starts

The opening of the file, as written. The whole thing — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Reviews

Reviews is a code-review tool for arbitrary diffs, not only GitHub PRs. An author pushes a diff plus a review packet (markdown that orders and annotates hunks into sections); reviewers read the packet, comment, and decide per section; --update adds patchsets.

Stack: Elixir 1.20 / Phoenix 1.8 / LiveView 1.2 (web), Rust CLI in cli/, Postgres, vanilla @pierre/diffs for diff rendering (no React). Bun manages assets/.

This file is for every coding agent (Claude Code, Codex, Cursor, …). CLAUDE.md is a symlink to it. Framework-level Phoenix/Elixir rules live in .claude/rules/phoenix-usage-rules.md; read that file before editing Elixir, HEEx or asset files.

Commands

Task Command
First setup mix setup (deps, DB, assets) and cd assets && bun install
Dev server ./bin/server (sources .env.local for GitHub OAuth, then mix phx.server on :4000). Check lsof -iTCP:4000 -sTCP:LISTEN first; a second server fails on bind.
Before committing mix precommit (compile with warnings as errors, unused deps, format, test)
Elixir tests mix test. Parallel runs or worktrees: MIX_TEST_PARTITION=<name> mix test gives each its own DB.
JS unit tests cd assets && bun run test
Assets mix assets.build (CI runs it; tailwind needs NODE_PATH, already wired)
CLI cd cli && cargo build --release, cargo test, cargo clippy --all-targets -- -D warnings, cargo fmt --check
Preview a change as a review reviews push from any checkout, then open the printed /r/<slug> URL; reviews push --update <slug> adds a patchset; reviews push --dry-run validates without sending

CI (.github/workflows/ci.yml) runs format check, compile with warnings as errors, bun install --frozen-lockfile, mix assets.build, and mix test. Match it locally before pushing.

Where things are

  • lib/reviews/ contexts: reviews.ex (reviews, patchsets), threads.ex, packet_section_decisions.ex, anchoring.ex, accounts.ex (users, agent identities, API tokens), code_snapshots.ex + code_storage/ (optional code.storage backend).
  • lib/reviews_web/live/review_live.ex is the review screen; its packet UI is in review_live/packet_components.ex, diff components in review_live/diff_components.ex. settings_live.ex holds identities and tokens.
  • lib/reviews_web/controllers/api/ is the JSON API the CLI uses. docs/CONTRACTS.md documents it and the LiveView hook events; update it with any API change.
  • assets/js/hooks/diff_renderer.js mounts Pierre; rendering code is in assets/js/diff_renderer/; dataset parsing goes through Zod schemas in assets/js/schemas.js.
  • assets/css/app.css imports tokens.css, components.css, packet.css (review UI, .review-* / .rev-*), landing.css, product-shell.css. Use the --ds-* tokens; do not add hex colours in components.
  • .plans/ holds design plans and is tracked. Read the plan for the area you touch before changing it. .plans/market-scan-2026-10.md lists product ideas with prior art.
  • skills/ are the agent skills shipped with the CLI installer (overview, writing packets, using Reviews locally). Keep them in sync with CLI flags.
  • docs/RELEASE.md is the release process; CHANGELOG.md has an Unreleased section to add to.

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.
