AGENTS.md

miru-web AGENTS.md is an instructions file for Codex, OpenCode from saeloun/miru-web. It costs 1,163 tokens per session, scanned A, original, MIT.

Repository instructions for working on the Miru web project. They define coding rules, testing requirements, browser checks, build commands, and how to preserve unrelated changes.

In plain words
What is it for?
Use them when changing the Miru web app, especially its browser-facing pages, JavaScript, TypeScript, builds, or tests.
Why use it?
They help prevent unverified fixes, broken browser behavior, accidental reversions, and incomplete JavaScript or TypeScript changes.

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

This is saeloun/miru-web's own configuration. It tells Codex and OpenCode how to work on miru-web 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 miru-web 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

miru-web 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 2mo 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.

This file is the source of truth for AI assistant behavior in this repository. If guidance conflicts elsewhere, prefer this file.

Scope: entire repository.

Keep this file short. Treat it as a router for repo-specific rules.

Core Repo Rules

  1. Never fake results. Do not claim something works unless you actually verified it.
  2. For UI changes, verify in a real browser on the running app.
  3. For JavaScript or TypeScript changes, always run rtk mise exec -- timeout 30 bin/vite build before handoff.
  4. For runtime-sensitive commands in this repo, prefer rtk mise exec -- <command>. If rtk blocks the task, fall back and say so plainly.
  5. Use apply_patch for manual file edits.
  6. Run focused specs for files you change before widening scope.
  7. For browser-facing fixes, verify on the local app with Playwright or PinchTab.
  8. Do not claim a React or JS crash is fixed unless the affected page loads successfully in the browser and is checked for console errors.
  9. If a change is verified and there is no explicit reason to hold it back, commit and push it when asked instead of letting the tree drift.
  10. Preserve unrelated work in a dirty tree. Do not revert user changes just to simplify your own task.
  11. When the user asks for a larger batch, keep going until the batch is done, blocked, or risky without input.
  12. When resolving GitHub issues and posting resolution comments (with user approval), include verification images/screenshots as evidence.
  13. Before merging any PR, inspect CodeRabbit review feedback and fix every actionable item. Do not merge with unresolved CodeRabbit feedback unless the user explicitly approves deferring a specific item.
  14. For GitHub issue fixes, always create or use a dedicated git worktree before editing files; do not make issue fixes directly in the primary checkout.

Repo Workflow

  • When a user gives a sequence like "finish A, then do B", complete A and continue into B without waiting.
  • On SPA pages, prefer settled route checks over generic networkidle when background requests stay alive.
  • If a user reports a live production bug, reproduce it on the real domain when practical before declaring root cause.

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.
