claw-mo-up

claw-mo-up is a skill for Claude Code, Codex from LeeJuOh/claude-code-zero. It costs 42 tokens per session (1,436 once invoked), scanned A, original, MIT.

A project command that starts or reopens the configured “mo” tool, which displays Markdown documentation in a browser.

In plain words
What is it for?
Use it to preview project documentation, start the viewer for a session, or restart it so new files appear.
Why use it?
It removes the need to remember the startup command and can refresh the viewer when file changes were missed.

Skill for Claude CodeCodex

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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

claw-mo-up 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 4d 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 — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.

claw-mo-up

Bring up the mo markdown viewer for the current project and open the browser. When a server is already running, restart it by default so new files on disk become visible (fsnotify can silently miss events).

For config schema, decision tree, --restart vs --clear semantics, and browser opening: read ${CLAUDE_PLUGIN_ROOT}/references/shared.md

Arguments

  • $ARGUMENTS (optional)
    • --reuse — Skip mo --restart when live matches config. Use this when the running session is known-good and the user explicitly wants zero interruption.

Steps

[!NOTE] With autosync enabled (default), /claw-mo-up is only needed to (a) start mo for the first time in a session, (b) recover from a silent fsnotify miss via mo --restart, or (c) reconcile a drifted runtime to saved config. Routine new-file visibility does not require a restart anymore.

  1. Prerequisites: command -v mo >/dev/null 2>&1. If missing, tell user brew install k1LoW/tap/mo and stop.

  2. Project key: git rev-parse --show-toplevel (fallback: $PWD).

  3. Read config from ${CLAUDE_PLUGIN_DATA}/config.json. If no entry for this project, tell the user to run /claw-mo-setup and stop.

  4. v1 migration: If the entry has patterns instead of groups, migrate to groups format and save back.

  5. Probe server: mo --status --json 2>/dev/null. Extract the server whose port matches $PORT.

  6. Branch on state — see the decision tree in shared.md:

    (a) No server on this port → start per group sequentially:

    mo --no-open -w 'pattern1' -w 'pattern2' --target groupName -p $PORT
mo --no-open -w 'pattern3' --target anotherGroup -p $PORT

    (b) Server running, live matches config:

    • Default: mo --restart -p $PORT — fresh fsnotify scan, session preserved. This is the main fix for the "docs exist on disk but don't show up in mo" class of bug.
    • If --reuse flag was passed: skip restart, reuse as-is.

    (c) Server running, live differs from config (treat config as source of truth):

    1. Show a concise diff (groups added/removed, patterns changed) so the user sees why a clear is happening
    2. printf 'y\n' | mo --clear -p $PORT
    3. Start per group as in (a)
    4. Mention that ad-hoc runtime edits were discarded; persist via /claw-mo-manage or /claw-mo-setup next time

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.
