ccreate-agent

name	ccreate-agent
description	Scaffold a new custom agent — reviewers, researchers, or workflow agents. Use when asked to create, scaffold, or add a new agent.
argument-hint	Describe the agent to create (e.g., 'Vue reviewer', 'Python linter')

Create Agent

Scaffold a new .agent.md file with correct VS Code Copilot frontmatter and structure.

Workflow

Step 1: Determine Agent Type

Ask the user what kind of agent they want to create:

1. Reviewer — a code review subagent (dispatched by the creview orchestrator)
2. Researcher — a read-only codebase exploration agent
3. Workflow — a user-facing agent for specific tasks

Step 2: Gather Details

Based on agent type, ask:

• Name — lowercase, hyphenated (e.g., vue-reviewer, python-linter)
• Description — what it does in one sentence
• Domain — what file types or patterns it targets (for reviewers)

Step 3: Generate the Agent File

For Reviewers

Reviewers are subagents dispatched by the creview orchestrator. They:

• Are hidden from the user dropdown
• Cannot be auto-invoked by other agents
• Have read-only tools only
• Follow the standard finding output format

---
name: [name]-reviewer
description: "[What it reviews] — [specific focus areas]"
user-invocable: false
disable-model-invocation: true
tools: ['search/codebase', 'search/usages']
---

The body should include:

• Clear role description
• What to look for (specific patterns, smells, or violations)
• Confidence calibration (High/Medium/Low with definitions)
• What NOT to flag (to avoid noise)
• Standard output format (Finding with Severity, Confidence, File, Category, Description, Suggestion)

For Researchers

Researchers are read-only subagents used by other agents for codebase exploration.

---
name: [name]
description: "[What it researches]"
user-invocable: false
disable-model-invocation: true
tools: ['search/codebase', 'search/usages', 'search/changes', 'web/fetch']
---

For Workflow Agents

Workflow agents are user-facing and can have full tool access.

---
name: [name]
description: "[What it does]"
argument-hint: "[Expected input]"
tools: ['*']
---

Step 4: Place the File

Write the agent file to .github/agents/[name].agent.md.

Step 5: Explain Auto-Discovery

For reviewers, explain:

• The creview orchestrator uses agents: ['*'] and auto-discovers all *-reviewer.agent.md files
• It reads the reviewer's description to determine if it's relevant to the current diff
• The reviewer will be dispatched automatically when files matching its domain are changed
• No configuration needed — just create the file and it's active
