Remarc: Instructions file for Claude Code

CLAUDE.md

Remarc CLAUDE.md is an instructions file for Claude Code from metedata/Remarc. It costs 2,084 tokens per session, scanned D, original, MIT.

Repository instructions for Remarc, a macOS menu bar app for adding comments to selected text, including its agent integrations and project rules.

In plain words
What is it for?
Use them when developing Remarc, its Claude Code or Codex plugins, or its Cursor integration.
Why use it?
They explain project-specific details that an agent needs before changing or testing the app.

Instructions file for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: reads .claude/ paths; mentions .claude-plugin; mentions CLAUDE.md.

This is metedata/Remarc's own configuration. It tells Claude Code how to work on Remarc 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 Remarc configures →

Runs only inside a plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else, and the catalogue could not identify which plugin ships it.

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 D, and why

Remarc CLAUDE.md scanned grade D with 2 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

**Codex is install-only: there is no cleanup, no latch, no durable flag, and it deletes nothing.** The app simply stopped writing `[mcp_servers.remarc]` into `~/.codex/config.toml`. Anyone carrying that table from an old

How it starts

The opening of the file, as written. The whole thing — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Remarc

macOS menu bar app (SwiftUI + AppKit) for contextual commenting on text selections.

  • Bundle ID: com.metepolat.Remarc
  • Min macOS: 14.0 (MACOSX_DEPLOYMENT_TARGET in app/Config/Shared.xcconfig is the source of truth), Swift 6.0+, LSUIElement (no dock icon)
  • Debug log: /tmp/remarc_debug.log (Debug builds only; release builds write no log file unless defaults write com.metepolat.Remarc debugFileLoggingEnabled -bool YES)
  • Data: ~/Library/Application Support/Remarc/comments.json (legacy fallback: data.json)

Agent integrations

Three harnesses, two different delivery models. Do not assume they work the same way.

Claude Code and Codex: plugin-based. Both install from the marketplace at https://github.com/metedata/remarc-agent-plugins, which is not built into the app. Two plugins:

  • remarc@remarc - required. MCP server + skill.
  • remarc-hooks@remarc - optional, experimental. Session-lifecycle hooks (off by default; user must /plugin install remarc-hooks@remarc explicitly).

Cursor: still fully app-managed. The app writes ~/.cursor/mcp.json and ~/.cursor/skills/remarc/SKILL.md via HarnessIntegrationManager / CursorMCPInstaller / SkillInstaller, driven by the Enable toggle in Preferences. Cursor's repo marketplaces are Teams/Enterprise-only, so there is no plugin path for individual users. Deliberately deferred, not overlooked - see docs/superpowers/plans/2026-08-06-codex-cursor-plugin-migration.md.

Per-harness plugin manifests (important)

The plugin repo ships THREE manifests over one shared payload, because the harnesses disagree about paths:

  • .claude-plugin/plugin.json + root .mcp.json using ${CLAUDE_PLUGIN_ROOT}. Claude Code substitutes it.
  • .codex-plugin/plugin.json -> codex-mcp.json using "args": ["mcp/dist/index.js"], "cwd": ".". Codex does NOT substitute ${CLAUDE_PLUGIN_ROOT} (nor ${PLUGIN_ROOT} / ${CODEX_PLUGIN_ROOT}) in plugin MCP args, and sets no plugin-root env var - it passes the literal string through, so the server never starts. A relative cwd, resolved against the installed plugin root, is the documented replacement (openai/codex#19582, discussion #28145). Codex prefers .codex-plugin over .claude-plugin when both exist, which is what keeps Claude Code unaffected.
  • .cursor-plugin/plugin.json - groundwork for a future Cursor Marketplace listing only. No app code consumes it.

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.

Remarc CLAUDE.md is an instructions file published in the GitHub repository metedata/Remarc (83 stars, last pushed 1mo ago), licensed MIT. It adds 2,084 tokens to every session, about $0.0083 per session on Opus 5.5. A static security scan graded it D with 2 findings (reads agent configuration directories, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
