Field Details

name (required)

  • Must be 1-64 characters
  • Lowercase letters, digits, hyphens only (a-z, 0-9, -)
  • Must not start or end with a hyphen
  • Must not contain consecutive hyphens (--)
  • Must match the parent directory name exactly
  • GoClaw uses directory name as the DB slug — name is also used as display name fallback

description (required)

  • Under 1024 characters (keep under 200 for concision)
  • Structure: [What it does] + [When to use it] + [Key capabilities]
  • Include trigger phrases users/agents would actually say
  • Mention relevant file types if applicable

license (optional)

  • Common: MIT, Apache-2.0, Proprietary
  • Can reference bundled file: "Proprietary. LICENSE.txt has complete terms"

compatibility (optional)

  • 1-500 characters
  • Describe environment requirements: intended product, system packages, network access
  • Most skills don't need this field

metadata (optional)

  • Arbitrary key-value map for additional properties
  • Suggested keys: author, version, category

allowed-tools (optional, experimental)

  • Space-delimited tool patterns pre-approved for this skill
  • Support varies between agent implementations

GoClaw Behavior

GoClaw reads only name and description from frontmatter (the Metadata struct). All other fields are stored as raw frontmatter JSONB in the DB for display purposes.

The slug (DB key) is always derived from the directory name, not from frontmatter:

skills/read-pdf/SKILL.md  →  slug = "read-pdf"

Renaming the directory creates a new skill entry. Same directory = upsert existing.

Description Examples

Good — specific with triggers:

description: Extracts text and tables from PDF files, fills PDF forms, and merges
  multiple PDFs. Use when working with PDF documents or when user mentions PDFs,
  forms, or document extraction.
description: Create, edit, and read Word .docx files. Triggers: 'Word doc',
  '.docx', reports, memos, letters, tracked changes, table of contents.

Bad — vague or missing triggers:

description: Helps with projects.                              # Too vague
description: Creates sophisticated documentation systems.      # No triggers
description: Implements the Project entity model.              # Too technical
