Outfit: Skill for Claude Code

.claude/skills/create-outfit/SKILL.md

create-outfit is a skill for Claude Code from MyceliumInc/Outfit. It costs 43 tokens per session (1,221 once invoked), scanned A, original, MIT.

A tool for creating an Outfit, a portable agent profile that defines its identity, abilities, permissions, and limits. It turns a description of the desired agent into a validated configuration.

In plain words
What is it for?
Designing and scaffolding specialized agents such as reviewers or report writers, specifying what they may and may not do, and validating the resulting Outfit configuration.
Why use it?
It helps define an agent's behavior and access boundaries clearly, reducing vague instructions and unnecessary permissions.

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

create-outfit 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 127 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Create an Outfit

You are helping the user author a new Outfit: a single declarative file that defines an agent persona that is portable across runtimes and enforced by the Outfit Gateway. Your job is to turn a fuzzy "I want an agent that does X" into a valid, minimal, least-privilege outfit spec, then validate it.

1. Understand the persona

Ask only what you cannot infer. You need enough to fill in:

  • name: kebab-case (a-z, 0-9, hyphen), e.g. release-manager.
  • what it is for: one-line description.
  • identity: how it should think and behave (becomes the system prompt).
  • what it must be able to do: maps to capabilities below.
  • what it must NOT do: shapes the scopes (least privilege).

Default to the narrowest set of capabilities that lets the persona do its job. A read-only reviewer should not get fs.write; a report writer should be scoped to a single output directory.

2. The spec

apiVersion: outfit/v1
name: <kebab-case>
description: <one line>
version: 0.1.0

identity:
  prompt: |
    <who the agent is, its goals, and how it behaves. Be specific about the
    boundaries you also enforce below, so the model and the gateway agree.>

capabilities: []     # the portable, gateway-enforced core (see ontology)
skills: []           # instruction bundles, inlined into the persona
integrations: []     # raw MCP servers, the escape hatch (non-portable)
extensions: {}       # runtime-specific extras (hooks, slash commands)

3. Capability ontology

Only these capability ids exist. Each is implemented and scope-checked by the gateway, so they behave identically on every runtime. The default posture is deny: an empty scope denies everything.

id scope shape
shell.exec allow / deny: command glob patterns
fs.read paths: path globs
fs.write paths: path globs
fs.list paths: path globs
http.fetch domains: hostname globs
web.search domains: hostname globs (+ provider)

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.
