watch

watch is a command for coding agents from rolecraft-sh/rolecraft. It costs 0 tokens per session (348 once invoked), scanned A, original, MIT.

A command that watches local skill files for changes and automatically syncs updated skills to configured agent folders.

In plain words
What is it for?
Use it to watch all local skills or one named skill, preview what would be watched, and stop the watcher with Ctrl+C.
Why use it?
It removes the need to reinstall a local skill manually every time its files change and records updated content hashes in the lockfile.

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

watch 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.

What it actually says

Description

Monitors skill source directories using node:fs FSWatcher. When a file changes, the skill is automatically re-installed to all its configured agent targets and the lockfile is updated with new content hashes.

Only local source skills can be watched. Remote (GitHub, npm, git) sources are skipped.

Examples

# Watch all local skills
rolecraft watch

# Watch a specific skill
rolecraft watch my-skill

# Preview without starting watchers
rolecraft watch --dry-run

Output

Node.js API

This command is also available as a programmatic function. See the Node.js API documentation for detailed usage.

import { watch } from 'rolecraft'
const { watchers, skills } = await watch('my-skill', process.cwd())

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.
