Command Creator

What it does

When your agent uses it

• Tasks that involve Hooks and plugins

Example prompts

• “Use the command-creator skill to create new Claude Code slash commands with frontmatter and validation”
• “/command-creator”

Requirements

• Pre-approved tools (allowed-tools): Read, Write, Edit, Bash, Grep, Glob

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

1. 1Capture intent -- what should the command do and who invokes it?
2. 2Pick scope -- project command, user command, or plugin command?
3. 3Define frontmatter -- description, argument hint, allowed tools, model if needed
4. 4Write command body -- instructions for Claude, not explanation for the user
5. 5Add validation context -- expected output, constraints, follow-up checks
6. 6Test and iterate -- invoke the command with representative arguments

What it can do on your machine

Read from SKILL.md and the folder at commit d64db2b. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Read
  • Write
  • Edit
  • Bash
  • Grep
  • Glob

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  No scripts in the folder and no shell commands in SKILL.md (its code samples are yaml and markdown).

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Links to these hosts (documentation or services it may open):

  • agentskills.io

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Command Creator loads about 977 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 313 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~38

When it runs · the whole SKILL.md, loaded when a task matches

~977

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

• NotePre-approves every shell command (allowed-tools: Bash)SKILL.md

  allowed-tools: Read, Write, Edit, Bash, Grep, Glob

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

$ARGUMENTS

Perform the requested task using this workflow:

1. Gather context from the repository.
2. Ask clarifying questions if critical information is missing.
3. Execute the task using the smallest safe set of changes.
4. Validate the result.
5. Summarize outcome and follow-up actions.

## Example

\`\`\`
/{command} example-argument
\`\`\`

## Rules

- **MUST** {non-negotiable rule}
- **NEVER** {forbidden action}

## Gotchas

- {environment-specific trap — only if the command has one; omit the section otherwise}

## When NOT to Use

- For {adjacent use case} -- use `/{other-command}` instead
- If {precondition} is not met
