agent-creator

agent-creator is a skill for Claude Code, Codex from hotovo/aider-desk. It costs 60 tokens per session (2,625 once invoked), scanned A, original, Apache-2.0.

A profile builder for AiderDesk, a tool for running coding agents. It helps define an agent’s instructions, available tools, permissions, subagents, and AI provider or model.

In plain words
What is it for?
Use it to create or configure an AiderDesk agent profile, including its purpose, tools, approval rules, subagents, and model choice.
Why use it?
It removes the need to hand-write and remember the settings for each agent. It also helps keep project-specific and global profiles organised.

    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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 1mo 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 Profile Creator

Create agent profiles stored as config.json in ~/.aider-desk/agents/{name}/ (global) or {project}/.aider-desk/agents/{name}/ (project-level).

Read all reference files before proposing a profile to ensure accuracy:

  • references/agent-profile-schema.md — Complete property reference
  • references/subagent-guide.md — Subagent config, system prompts, context memory, filtering
  • references/tool-approval-guide.md — All tool groups, correct tool keys, approval strategies
  • references/profile-examples.md — Complete working examples

Q&A Process

Gather complete requirements before proposing a profile. Ask focused questions, propose internally, and present one final summary for approval.

Step 1: Purpose & Behavior

Ask: "Describe the agent's purpose and what it should do."

Based on the response, internally propose:

  • Name (derived from purpose)
  • Max iterations (default 0 = unlimited; use a finite value like 250 for bounded tasks, or lower for focused tasks like review/analysis: 150)
  • Tool groups (based on purpose — see Step 3)
  • Custom instructions (free-text guidance appended to the system prompt)
  • System prompt — does the agent need a fully custom system prompt that replaces the default built-in one? If the user describes specific behavioral constraints, role, or identity, propose a systemPrompt.
  • Subagent config — should this profile be usable as a subagent? If yes, gather subagent-specific system prompt, invocation mode, color, description, and context memory mode.

Step 2: Provider & Model

Ask: "Which provider/model? (format: provider/model, e.g., anthropic/claude-sonnet-5)"

  • Split by first slash to get provider and model
  • Use as-is (correct obvious typos only)
  • If the user does not specify, default to anthropic / claude-sonnet-5 (matching DEFAULT_AGENT_PROFILE / DEFAULT_PROVIDER_MODELS in packages/common/src/agent.ts). You may ask the user for their preferred provider/model, but if none is given, use these defaults.
  • Optionally ask about temperature and maxTokens if the purpose implies precision (low temp) or creativity (high temp)

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.
