Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00050 | $0.01616 |
| Opus 5 | $0.00025 | $0.00808 |
| Sonnet 5 | $0.00010 | $0.00323 |
| Haiku 4.5 | $0.00005 | $0.00162 |
Grade C, and why
claw-mo-open scanned grade C 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 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.

The opening of the file, as written. The whole thing — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.
claw-mo-open
Add a specific file, directory, or piped markdown content to the running mo server and open the browser directly on that file.
For config schema, HTTP API, deep-linking, and browser opening: read ${CLAUDE_PLUGIN_ROOT}/references/shared.md
Arguments
$ARGUMENTS— one of:- File path:
docs/spec.md - Directory:
docs/(added as a watch pattern) -or--stdin: read markdown from stdin (e.g.,cat notes.md | /claw-mo-open -)- Optional
--group <name>to pin the target group (otherwise auto-detected)
- File path:
- Examples:
/claw-mo-open docs/spec.md/claw-mo-open plans/ --group planssome-tool | /claw-mo-open - --group scratch
Steps
-
Parse
$ARGUMENTS:- Detect
--stdinor a bare-→ stdin mode - Otherwise resolve file/dir path with
realpath - Extract
--group; if absent, auto-detect from config (match the file path against each group's patterns, fall back todefault)
- Detect
-
Prerequisites:
command -v mo >/dev/null 2>&1. -
Project key:
git rev-parse --show-toplevel(fallback:$PWD). -
Read config from
${CLAUDE_PLUGIN_DATA}/config.json. -
Check running server:
mo --status --json→ is a server on$PORT? -
If server is running AND config exists — verify sync before mutating:
- Compare live group→patterns to saved config (see
shared.md) - If drifted: tell the user that
/claw-mo-upwould clear+rebuild this runtime; ask whether to resync first or add into the drifted runtime - If they resync: clear, restart from config, then continue
- If they decline: continue but warn the change won't survive the next
/claw-mo-upunless config is updated
- Compare live group→patterns to saved config (see
-
Add the content based on mode:
(a) File path, server running:
curl -s -X POST "http://localhost:$PORT/_/api/groups/$GROUP/files" \ -H 'Content-Type: application/json' \ -d "{\"path\": \"$(realpath file.md)\"}"(b) Directory, server running:
curl -s -X POST "http://localhost:$PORT/_/api/patterns" \ -H 'Content-Type: application/json' \ -d "{\"pattern\": \"$(realpath dir)/**/*.md\", \"group\": \"$GROUP\"}"
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.

claw-mo-open is a skill published in the GitHub repository LeeJuOh/claude-code-zero (51 stars, last pushed 4d ago), licensed MIT. It adds 50 tokens to every session and 1,616 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
