Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00065 | $0.04430 |
| Opus 5 | $0.00032 | $0.02215 |
| Sonnet 5 | $0.00013 | $0.00886 |
| Haiku 4.5 | $0.00006 | $0.00443 |
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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

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:
- Import a Skill from a URL — supply a remote SKILL.md URL, fetch the content, and create
- Bulk import from a Git repository — clone a Git repo, scan all SKILL.md files, and selectively import
- Manage existing Skills via API — list, read, update, delete, enable/disable Skills
- Author SKILL.md directly via AgentFS — use the Write/Edit tools to create Skills on the filesystem
- 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..."
}
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.
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.
- 12d ago First seen · 573 lines · 65 tokens per session scan A 373f19b8589d
manage-skills is a skill published in the GitHub repository desirecore/market (2 stars, last pushed yesterday), licensed MIT. It adds 65 tokens to every session and 4,430 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other skills, from other repositories
author-skill
Use when authoring a NEW rsc skill or editing an existing one — scoping it to one job, writing the description that decides whether it ever loads, splitting the body into references/, writing its evals, auditing it against the rubric. NOT building a product feature (that is specify) and NOT designing an agent loop…
Autoresearch
Iteratively improve a weak skill through score, tweak, and retest loops. Run against a target skill, define failure mode and rubric, execute the loop, and get a scored report with recommendations.
skill-scorer
A review tool for Agent Skills, which are instruction files that guide coding agents. It supports skills made for Cursor, Claude, and OpenClaw.
Combo Developer
Automatically routes requests to the correct skill (Planner, Debugger, Advisor, etc.) based on first message content.
skill-creator
Propose, test, validate, and improve Skill candidates without changing active files - generate reviewable SKILL.md and handler.js drafts, run test evaluations, and optimize descriptions for better triggering.
agent-writer
Write new agent definitions, skill files, and agent configurations. Use when someone asks to "create a new agent", "write a skill", "define an agent", or needs to create reusable AI agent instructions for any platform. This is the meta-skill for creating other skills and agents in the polyagent-skills format.
