What it does

Skill Creator is an agent skill from openclaw/openclaw. Author or review AgentSkills: create, repair, validate, or restructure SKILL.md files and bundled resources.

Its SKILL.md is about 580 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts (for example `scripts/package_skill.py`, `scripts/quick_validate.py` and `scripts/test_package_skill.py`).

It sits in Agent Workflows, covering Skill authoring. The repository describes itself as: The AI that really does things. Any OS. Any Platform. The lobster way. 🦞. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Skill authoring

Example prompts

  • “/skill-creator”

Requirements

  • Python 3

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Establish the contract.
  2. Choose invocation.
  3. Structure the skill.
  4. Draft and persist.
  5. Validate.

What it can do on your machine

Read from SKILL.md and the folder at commit f8e594e. 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

    Ships 4 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • 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

Skill Creator loads about 576 tokens when it runs. Until then it costs about 31 tokens; SKILL.md has 264 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~31
When it runs · the whole SKILL.md, loaded when a task matches
~576

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); the scripts in this folder are not scanned.

Skill Creator

Workflow

  1. Establish the contract.

    • Read the existing skill and its resources, or collect concrete requests for a new skill.
    • Separate actual workflow branches from synonyms for the same branch.
    • Done when: every branch has a concrete trigger, expected outcome, and persistence target.
  2. Choose invocation.

    • Model-discoverable: write a model-facing description; omit disable-model-invocation.
    • Manual-only: set disable-model-invocation: true; write a human-facing summary.
    • Direct tool command: add command-dispatch: tool, command-tool, and command-arg-mode only when the command bypasses the model.
    • Done when: frontmatter matches how the skill will actually be reached.
  3. Structure the skill.

    • Map shared ordered procedure to SKILL.md; end every step with a checkable completion criterion and finish with verification.
    • Keep routing conditions in description; start the body with execution.
    • Map branch-only detail to references/, deterministic helpers to scripts/, output resources to assets/, and optional UI metadata to agents/.
    • Done when: every planned resource has one purpose and a direct pointer from SKILL.md.
  4. Draft and persist.

    • Live workspace skill: use skill_workshop to create or revise a pending proposal; keep live files unchanged until apply.
    • Repository-owned skill source: use the repository's normal edit and review workflow.
    • Done when: the proposal or source diff implements every branch from step 1 and contains every resource from step 3.
  5. Validate.

    • Run python {baseDir}/scripts/quick_validate.py <skill-directory> and execute every touched helper's focused test.
    • Done when: frontmatter passes, resource pointers resolve, and every touched helper passes its focused test.

Frontmatter

Required: name, description.

OpenClaw also supports metadata, homepage, license, allowed-tools, user-invocable, disable-model-invocation, command-dispatch, command-tool, and command-arg-mode. Add optional fields only when they change runtime behavior or discovery.
