What it does

Agent Creator is an agent skill from aiskillstore/marketplace. Creates specialized AI agents with optimized system prompts using the official 4-phase SOP methodology from Desktop .claude-flow, combined with evidence-based prompting techniques and Claude Agent SDK implementation. Use this skill when creating production-ready agents for specific domains, workflows, or tasks requiring consistent high-quality performance with deeply embedded domain knowledge.

Its SKILL.md is about 4.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `skill-report.json`).

It sits in AI & LLM Engineering, covering Building AI agents, Operations and SOPs and Prompt engineering. It works with Claude Agent SDK. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.

When your agent uses it

  • Creating production-ready agents for specific domains
  • Tasks requiring consistent high-quality performance with deeply embedded domain knowledge

Example prompts

  • “Use the agent-creator skill to create specialized AI agents with optimized system prompts using the official 4-phase SOP methodology from Desktop…”
  • “/agent-creator”

Requirements

  • Python 3

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Initial Analysis & Intent Decoding (30-60 minutes)
  2. Meta-Cognitive Extraction (30-45 minutes)
  3. Agent Architecture Design (45-60 minutes)

What it can do on your machine

Read from SKILL.md and the folder at commit ad8daf7. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown and python).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Agent Creator loads about 4.8k tokens when it runs. Until then it costs about 103 tokens; SKILL.md has 948 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~103
When it runs · the whole SKILL.md, loaded when a task matches
~4.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 948 words (~4,751 tokens).

“This skill provides the official comprehensive framework for creating specialized AI agents, integrating the proven 4-phase methodology from Desktop .claude-flow with Claude Agent SDK implementation and evidence-based prompting techniques.”
