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

manage-skills scanned grade A with 1 finding 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 12d 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.

manage-skills Skill

L0: One-line Summary

Manage the full lifecycle of Skills—import, author, install, update, and delete.

L1: Overview and Use Cases

Capability

manage-skills is a Meta-Skill that gives DesireCore the ability to manage the Skill system. It covers five core operations:

  1. Import a Skill from a URL — supply a remote SKILL.md URL, fetch the content, and create
  2. Bulk import from a Git repository — clone a Git repo, scan all SKILL.md files, and selectively import
  3. Manage existing Skills via API — list, read, update, delete, enable/disable Skills
  4. Author SKILL.md directly via AgentFS — use the Write/Edit tools to create Skills on the filesystem
  5. Bulk operations and cross-Agent copying — bulk enable/disable/delete, plus copy Skills to other Agents

Use Cases

  • The user wants to import community-shared Skills from platforms like GitHub
  • The user wants to install a new Skill on an Agent to enhance its capabilities
  • The user needs to author a custom Skill to teach the Agent a new workflow
  • The user wants to bulk-manage existing Skills (enable/disable/delete)
  • The user wants to copy one Agent's Skill to another Agent
  • The user needs to view or edit the contents of a Skill

Core Value

  • Self-extension: an Agent can autonomously expand its capability boundary by importing or authoring Skills
  • Governable: every Skill change goes through the API or filesystem operations and is traceable and auditable
  • Flexibility: supports both API import and direct filesystem authoring to fit different scenarios

L2: Detailed Specification

1. Import a Single Skill from a URL

For importing a single SKILL.md file (e.g. a GitHub raw link).

Step 1: Fetch the remote content

POST /api/skills/fetch-url
Content-Type: application/json

{
  "url": "https://raw.githubusercontent.com/user/repo/main/my-skill/SKILL.md"
}

Success response (200 OK):

{
  "content": "---\nname: My Skill\ndescription: ...\n---\n\n# Skill content..."
}

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
