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.

SkillSpector: 8 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Never auto-execute commands that modify files, send data, or alter system state.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00089 | $0.01908 |
| Opus 5 | $0.00044 | $0.00954 |
| Sonnet 5 | $0.00018 | $0.00382 |
| Haiku 4.5 | $0.00009 | $0.00191 |
Grade A, and why
find-skills 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 9d 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 — 171 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Find Skills
This skill helps you discover and install skills from the open agent skills ecosystem.
CRITICAL RULES
- ALWAYS search first: When a user asks to install/find/add ANY skill, your FIRST action must be running
skills find <query>in the sandbox. - NEVER create from scratch without searching: Even for simple-sounding skills like "hello-world", search first.
- Use the CLI directly: The
skillsCLI is pre-installed globally in the sandbox. Useskillsdirectly (NOTnpx skills— npx causes unnecessary download prompts). - Install to session workspace: Use
HOME=<workspace_dir> skills add ... -g -y --agent '*'so skills land in the current session's workspace (visible in the task file viewer). - Call propose_skill_save: After installing and testing a skill, ALWAYS call the
propose_skill_savetool with the skill name so the user can choose to save it permanently.
When to Use This Skill
Use this skill when the user:
- Asks to install a skill (e.g., "install hello-world skill", "安装一个 skill")
- Asks to find or search for a skill (e.g., "find a skill for X", "找一个 skill")
- Mentions a skill by name (e.g., "hello-world skill", "react testing skill")
- Asks "how do I do X" where X might be a common task with an existing skill
- Says "find a skill for X" or "is there a skill for X"
- Asks "can you do X" where X is a specialized capability
- Expresses interest in extending agent capabilities
- Wants to search for tools, templates, or workflows
What is the Skills CLI?
The Skills CLI (skills) is pre-installed globally in the sandbox. It is the package manager for the open agent skills ecosystem.
IMPORTANT: Always use skills directly, NEVER use npx skills (npx will try to re-download and prompt for confirmation).
Key commands:
skills find [query]- Search for skills by keyword (use this FIRST)HOME=<workspace_dir> skills add <package> -g -y --agent '*'- Install a skill to session workspaceskills list -g- List installed skillsskills check- Check for skill updates
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.
- 9d ago First seen · 171 lines · 89 tokens per session scan A 7ad849f72a08
find-skills is a skill published in the GitHub repository gabrielmoreira/agent-skills-mirror (17 stars, last pushed yesterday), licensed MIT. It adds 89 tokens to every session and 1,908 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
