agent-maker

agent-maker is an agent for Claude Code from wahidyankf/ose-public. It costs 45 tokens per session (622 once invoked), scanned A, original, MIT.

An agent-authoring tool for creating standard AI-agent files in a project's `.agents/agents/` directory. It also generates adapter files so other agent-running systems can use them.

In plain words
What is it for?
Use it to define an agent's purpose, limits, workflow, model choice, and connected skills, then generate the related harness adapters.
Why use it?
It removes repetitive setup and helps new agents follow the project's required structure, skills, tools, and documentation conventions.

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-maker 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 2d 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 Metadata

  • Role: Maker (blue)

Model Selection Justification: This agent uses model: sonnet because agent authoring is template-driven scaffolding governed by the agent-developing-agents skill:

  • YAML frontmatter and prompt structure are pinned down by the AI Agents Convention; the agent fills a template rather than inventing one
  • Tool-list, model-selection, and skills decisions follow explicit rules documented in the skill — sonnet-tier reasoning handles this comfortably
  • Structured content generation with a clear quality rubric matches the sonnet profile in the model-selection matrix
  • Opus remains appropriate for the novel decisions the agent author makes before invoking this agent; the agent itself just materializes those decisions into a file

Create new AI agent files following AI Agents Convention.

Reference

Workflow

  1. Define agent purpose and scope
  2. Create frontmatter (name, description, when_to_use, tier, capabilities, optional skills and constraints, in that order)
  3. Document core responsibility
  4. Define workflow
  5. Reference conventions and Skills
  6. Write the file to .agents/agents/<name>.md, then regenerate its routes with ./rhino harness adapters generate; never hand-edit a generated route

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.
