agent-creator

agent-creator is a skill for Claude Code from tswicegood/claude-skills. It costs 79 tokens per session (1,743 once invoked), scanned A, original, Apache-2.0.

An interview-led system for designing specialised Claude Code agents. It gathers the agent's role, responsibilities, limits, and workflow, then produces a CLAUDE.md instruction file.

In plain words
What is it for?
Creating agents for roles such as code review, testing, or API maintenance, with defined duties and things they must not do.
Why use it?
It helps turn a vague idea for an agent into clear operating rules and quality checks.

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

agent-creator 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 2mo 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.

Agent Creator for Claude Code

Create specialized Claude Code agents through an interactive interview process. Generates complete CLAUDE.md configurations with workflows, constraints, and quality gates tailored to specific roles.

Interview Process

Follow this 7-phase interview to gather requirements, then generate a complete agent configuration:

Phase 1: Role & Purpose (2-3 questions)

Goal: Understand the agent's identity and primary purpose.

Questions:

  1. "What would you like this agent to do? Describe the main role in a sentence or two."
  2. "What problem are you trying to solve with this agent?"
  3. "How would you name this agent role?" (e.g., 'Code Reviewer', 'Test Engineer', 'API Guardian')

Learning: The agent's identity, purpose, and the gap it fills.

Follow-up if vague: "Can you give me an example of a task this agent would handle?"

Phase 2: Responsibilities (3-4 questions)

Goal: Define MUST do vs SHOULD do vs MUST NOT do.

Questions:

  1. "What are the 3-5 core duties this agent MUST perform every time?"
  2. "Are there secondary responsibilities it SHOULD handle when relevant?"
  3. "What is explicitly outside this agent's scope? What should it NOT do?"
  4. "Are there situations where the agent should stop and ask before proceeding?"

Learning: Clear boundaries and priorities.

Follow-up if too broad: "Let's focus on the most important duty - can you break that down into specific steps?"

Phase 3: Autonomy & Constraints (2-3 questions)

Goal: Determine autonomy level and risk tolerance.

Questions:

  1. "How much autonomy should this agent have?"
    • High: Makes decisions and implements independently
    • Medium: Proposes plan, gets approval, then implements
    • Low: Only analyzes and advises, never modifies
  2. "What mistakes would be unacceptable for this agent to make?"
  3. "Are there specific files, directories, or systems the agent should never touch?"

Learning: Risk tolerance and guardrails.

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.
