add_command

Claude Code specific: this skill manages Claude Code configuration (settings.json wiring). Other agents do not consume what it produces.

Create a skill

Slash commands in this project live in .claude/skills/<name>/SKILL.md. Each skill is a markdown file with YAML frontmatter.

Step 1 — Create the file

Create .claude/skills/<name>/SKILL.md where <name> is the command name (lowercase, hyphen-separated).

Step 2 — Write the frontmatter

---
name: <name>
description: <What it does and when to use it. Third person. Include trigger keywords.>
when_to_use: <Extra trigger context — action phrases the user might say.>
argument-hint: "<expected arguments>"
allowed-tools: Bash Read Write   # tools pre-approved while this skill is active
model: sonnet                    # optional model override
effort: medium                   # low | medium | high | xhigh | max
disable-model-invocation: true   # true = user-only; Claude won't auto-invoke
user-invocable: false            # false = Claude-only background knowledge
context: fork                    # fork = runs in isolated subagent
---

Not all fields are required — only include what changes the default behaviour.

Step 3 — Write the body

Run this command to <what it does>.

## Steps

1. <step one — prefer shell commands over prose>
2. <step two>

## Rules

- <constraint if any>

$ARGUMENTS expands to the full argument string. Use $1, $2 for positional args.

Guidelines

• Name: lowercase, hyphen-separated, max 64 chars
• Description quality is load-bearing: if Claude doesn't trigger it automatically, the description is too vague — add keywords users would naturally say
• No file reads in the body: embed what the agent needs inline; don't say "read X first"
• Side-effect commands: set disable-model-invocation: true so only the user can invoke them
• Background conventions: set user-invocable: false so Claude loads them automatically
