alook: Instructions file for Codex

AGENTS.md

alook AGENTS.md is an instructions file for Codex, OpenCode from alookai/alook. It costs 2,289 tokens per session, scanned A, original, Apache-2.0.

A set of instructions for Alook, a service that keeps a command-line coding agent running and gives it an email address. It describes the project’s web, command-line, email, and connection components, along with required development rules.

In plain words
What is it for?
Use it when changing Alook’s CLI, web app, email handling, real-time connections, database queries, releases, or end-to-end browser tests.
Why use it?
It prevents common maintenance problems such as losing state in memory, checking access too late, or overwriting another person’s unfinished work. It also defines the checks required before a change is considered ready.

Instructions file for CodexOpenCode

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

This is alookai/alook's own configuration. It tells Codex and OpenCode how to work on alook 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 alook configures →

About the project

Alook is a local-first collaboration service where people and coding agents share rooms, channels, servers, and direct messages. Teams use it to reach agents running on their own machines, while the catalogue instructions help coding agents work with Alook.

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

alook 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 14d 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 — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Alook

Alook's main purpose is to make the cli agent always on, and give it a email address.

  • plans/: place your dev plans (gitignored, local only)
  • src/shared: shared types, schema, queries, validators
  • src/web: main Next.js app on Cloudflare Workers (D1 + R2); the independently built Blog app lives at src/web/blog
  • src/app: local app CLI
  • src/daemon: agent runtime and daemon CLI
  • src/email-worker: inbound email Cloudflare Worker
  • src/ws-do: WebSocket Durable Object worker

MUST

  • Don't write comment: comment may be outdated, code never. Unless the comment are specs and rules.
  • run pnpm typecheck, pnpm test as the final check when you think the code is ready.
  • service must be STATELESS! All the state must be in DB or local, never put important states in memory.
  • scope the queries before, not check the ownership after. don't query data then check if the data belongs to a workspace, use workspace id ahead to query the data.
  • respect others' works, don't reset any other git changes just because it's not done by you, others may working at the same time, never revert anything without asking the user.
    • don't stash others' works, you can wait, but stash others' work will cause many problems.

Release — Unified Version Bump

All workspace packages share one version. Use pnpm bump to release:

pnpm bump 0.0.11      # explicit version (v prefix optional)
pnpm bump patch        # auto-increment patch/minor/major
pnpm bump patch --min-cli  # also update MIN_CLI_VERSION in src/web/wrangler.toml
pnpm bump patch --desktop  # trigger desktop build

This updates every src/*/package.json and commits release: vX.Y.Z. Add --min-cli when the release contains breaking changes that require users to update their CLI. Add --desktop when the release includes desktop app changes that need a new build. Mobile store releases are not configured; add current signing accounts and rebuild the release workflow before exposing a mobile release flag.

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.
