What it does

Fastclaw Skill Guide is an agent skill from fastclaw-ai/fastclaw. Create new skills for FastClaw agents. Use when the user asks to create a skill, turn a workflow into a skill, or build reusable automation. Also use when discussing skill format, structure, or best practices.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering Skill authoring. The repository describes itself as: Multi-Agent Framework.

When your agent uses it

  • The user asks to create a skill
  • Turn a workflow into a skill
  • Build reusable automation
  • Discussing skill format

Example prompts

  • “/fastclaw-skill-guide”

Requirements

  • A credential in API_KEY

Workflow steps

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

  1. Agent workspace — {agentDir}/skills/ — skills specific to this agent
  2. Team — {teamDir}/skills/ — shared within a team
  3. User installed — ~/.fastclaw/skills/ — user-level skills
  4. OpenClaw compatible — ~/.openclaw/skills/ — installed via OpenClaw
  5. System bundled — npm global locations
  6. Extra dirs — configured in fastclaw.json

What it can do on your machine

Read from SKILL.md and the folder at commit d2ebed1. 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).

    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 these keys or tokens, usually read from environment variables:

    • API_KEY

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

Context cost

Fastclaw Skill Guide loads about 1.2k tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 436 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~58
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

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

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 436 words (~1,221 tokens).

“Guide for creating new skills that FastClaw agents can discover and use.”
