md-redline AGENTS.md

md-redline AGENTS.md is an instructions file for Codex, OpenCode from dejuknow/md-redline. It costs 29,130 tokens per session, scanned A, original, MIT.

Repository instructions for md-redline, a local web app for placing review comments directly in Markdown files. They describe the React frontend, Hono server, command-line tool, API, and documentation rules.

In plain words
What is it for?
Use them when working on the web interface, server routes, command-line commands, Markdown comment parsing, agent handoff prompts, or end-to-end tests.
Why use it?
They help an agent understand the project's layout and preserve the agreed source of truth when changing code or documentation. Hono is the web server framework used by the app.

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

md-redline 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 5d 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 — 1,881 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This is the single source of truth for agent-facing docs. CLAUDE.md contains only Claude-specific skill routing and points here. Do not duplicate content between the two files.

Repo snapshot

  • Local web app for inline review comments in markdown files
  • Frontend: React 19 + TypeScript + Tailwind CSS v4 + Vite 8
  • Backend: Hono server in server/index.ts
  • CLI entry: bin/md-redline, exposed as mdr and md-redline; the body is bin/cli.js

Architecture overview

A Hono server serves both a Vite-built React SPA and a REST API. An optional MCP stdio server lets AI agents request human review and wait for feedback.

Directory layout

  • bin/md-redline — published entry point (mdr command), a shim that imports bin/cli.js
  • bin/cli.js — the CLI itself. Starts server, opens browser, handles mdr mcp install.
  • server/ — Hono app, routes, review session store, MCP stdio layer
  • src/ — React SPA (Vite + TypeScript + Tailwind)
  • src/lib/comment-parser.ts — core parser for inline comment markers
  • src/lib/agent-prompts.ts — prompt builder for agent handoff
  • e2e/ — Playwright E2E tests
  • eval/ — eval harness and fixtures

Behavior that matters

  • Comments are stored inline as <!-- @comment{...} --> markers immediately before their anchor text.
  • Default workflow: comments are instructions to an agent, and addressed markers should be removed.
  • Optional resolve workflow adds open / resolved status for human review.
  • MarkdownViewer.tsx owns highlight DOM imperatively via refs; React does not reconcile the rendered markdown subtree.
  • Overlapping comments are allowed and depend on marker position plus stored anchor/context for rematching.
  • URL boot params: a ?file= boot opens that file active on top of the restored tab session, and ?dir= re-roots the explorer with tabs restored as saved; only ?review= skips session restore.

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.
