agent-creator

agent-creator is a command for Claude Code from frankxai/Starlight-Intelligence-System. It costs 46 tokens per session (497 once invoked), scanned A, original, MIT.

A command that creates a new agent profile, meaning a file describing an agent’s role, voice, skills, and working rules, and adds it to the project’s registries.

In plain words
What is it for?
Creating agent profiles under the project’s agent folders, assigning their domain and voice, listing their starting skills, and checking that registry tests still pass.
Why use it?
It handles the required file structure and duplicate checks so a new agent is registered consistently with the rest of the project.

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 6d 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

/agent-creator

Generate a new agent profile markdown file, register it in the canonical registries, and verify that the symmetry checks remain green.

Parameters

  • <agent-name>: Name of the agent (e.g., marine-acoustics, space-orbit).
  • --domain: Core domain slug (e.g., marine-intelligence, space-cosmos, longevity).
  • --voice: Voice profile from VOICES.md (e.g., specialist, architect, synthesizer).
  • --skills: Comma-separated list of initial active skills.
  • --path: Optional target folder path (for writing to a modular sub-repository directory, defaulting to agents/).

Execution Steps

  1. Format Verification: Ensures the agent name matches lowercase + hyphen syntax ([a-z][a-z0-9-]*).
  2. Duplicate Check: Scans AGENTS.md and agents/ directory to prevent naming collisions. If a collision is found, suggests suffix and prompts.
  3. Template Generation: Scaffolds the markdown file using the canonical agent template, injecting YAML frontmatter (name, tier, domain, voice), mission statement, active skills, reasoning protocols, and quality gates.
  4. Registry Append: Appends the agent metadata row and file link to agents/AGENT_REGISTRY.md and root AGENTS.md.
  5. Validation Check: Automatically executes tsc --noEmit and npm test test/v76.test.ts to ensure agent registry symmetry is preserved.

Changes

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.
