live-markdown-mcp: Instructions file for Codex

AGENTS.md

live-markdown-mcp AGENTS.md is an instructions file for Codex, OpenCode from kschroeder/live-markdown-mcp. It costs 225 tokens per session, scanned A, original, MIT.

Repository instructions for live-previewing Markdown files before editing documents such as plans, design documents, and READMEs. Markdown is plain text with simple formatting marks.

In plain words
What is it for?
Use it when creating or editing a substantial Markdown file: scope its path once with the Markdown preview tool, then edit the file normally.
Why use it?
The preview shows the rendered document while it is being written and avoids repeatedly opening a browser or previewing unrelated files.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is kschroeder/live-markdown-mcp's own configuration. It tells Codex and OpenCode how to work on live-markdown-mcp 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 live-markdown-mcp 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

live-markdown-mcp 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.

What it actually says

Agent instructions — MarkdownMCP

When to preview markdown

If you will create or edit a markdown file that benefits from rendered preview (plans, design docs, READMEs with tables/diagrams, long docs), put it in scope once before the first write.

Tool

Use MCP server markdown-mcp:

scope_markdown({ path: "<absolute or workspace-relative .md path>" })
  • Call before first write (the file may not exist yet).
  • Call at most once per path per session unless the path changed.
  • Do not call again for ordinary edits — the hub reloads from disk.
  • Do not open browsers yourself; the hub owns that.
  • Prefer absolute paths when you know them.

Do not

  • Spam scope/reload tools
  • Scope unrelated files
  • Scope secrets or paths outside the user's project without need

After scoping

Write the markdown with the normal edit tools. The user sees live updates in MarkdownMCP tabs (unread dots, optional change highlights, history).

Changes

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.
