At a glance
Searches skills.sh for agent skills you do not have yet, checks their quality, presents the option and installs only after you confirm.
- Works in 6 steps: check the leaderboard → search for skills → verify quality before recommending → …
- You ask whether a skill exists for a task, or want to add a capability
- SKILL.md covers When to use this skill, Step 1 — check the leaderboard, Step 2 — search for skills and Step 3 — verify quality before…, plus 5 more sections
- Calls npx
What it does
When you ask for a skill for some task, or how to do a common task that probably has one, the agent first checks the skills already installed in its context. If none fits, it looks at the skills.sh leaderboard and then searches with the Skills CLI through `npx`, falling back to browsing the site and pasting the SKILL.md if `npx` is missing. Search terms are short, such as react performance or pr review.
Search results are never enough to recommend a skill. The agent weighs install counts, the reputation of the publishing organization and the source repository's popularity, treating low numbers with skepticism. It then describes the candidate to you and waits for a yes. Installation either writes the SKILL.md directly into the project's skills folder and reloads the catalog, which always works, or uses the CLI, which needs Node.js.
When your agent uses it
- You ask whether a skill exists for a task, or want to add a capability
- Evaluating a third-party skill's source before installing it
- Installing a skill from skills.sh into the current project
Example prompts
- “Find a skill that helps with changelog writing.”
- “Is there a skill for reviewing pull requests? Check quality before recommending one.”
- “Install the React performance skill you found, now that I have confirmed it.”
Requirements
- Network access to skills.sh
- Node.js with npx for the CLI search and install route
Workflow steps
6 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit c339821. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
skills.sh
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Agent Skill Finder loads about 1.1k tokens when it runs. Until then it costs about 52 tokens; SKILL.md has 492 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md

Download SKILL.mdSave it as
.claude/skills/find-skills/SKILL.md (or your agent's skills folder).- name
- find-skills
- description
- Discover/install NEW agent skills from external sources (skills.sh). Use for capabilities you lack, e.g. "find a skill for X". Do NOT use to list skills you already have; see `<available_skills>`.
Find skills
When to use this skill
- The user asks "find a skill for X", "is there a skill that does X"
- The user asks "how do I do X" where X is a common task with a likely existing skill
- The user wants to extend Horizon's capabilities with a new skill
Before searching externally, check the <available_skills> block in your
context — the user may already have a relevant skill installed.
Step 1 — check the leaderboard
Before running any CLI command, check skills.sh to see whether a well-known skill already covers the domain. The leaderboard ranks by total installs, surfacing the most popular and battle-tested options.
Step 2 — search for skills
If the leaderboard doesn't cover the user's need, search via the Skills CLI:
bash(command="npx --yes skills find <query>")Examples:
| User says | Search |
|---|---|
| "make my React app faster" | npx --yes skills find react performance |
| "help with PR reviews" | npx --yes skills find pr review |
| "create a changelog" | npx --yes skills find changelog |
If npx is unavailable the command will fail — fall back to browsing
skills.sh manually and pasting the SKILL.md content.
Step 3 — verify quality before recommending
Never recommend a skill based solely on search results.
- Install count — prefer 1 000+ installs; treat anything under 100 with skepticism
- Source reputation — official organisations (
vercel-labs,anthropics,microsoft) are more trustworthy than unknown authors - GitHub stars — check the source repo; a skill from a repo with <100 stars is a yellow flag
Step 4 — present the option to the user
I found a skill that might help: "react-best-practices" from Vercel Engineering
provides React and Next.js performance guidelines (185K installs).
Shall I install it?Only proceed to installation after the user confirms.
Step 5 — install
Option A — write SKILL.md directly (always works)
If you have the skill content (pasted by the user, retrieved from skills.sh, or constructed from the search result):
write(".agents/skills/<name>/SKILL.md", content)
load_skill(action="reload")write creates the directory if it does not exist. load_skill(action="reload")
refreshes the <available_skills> catalog (plus extensions and manifest) on
the next turn.
Show full SKILL.md (191 more words)Show less
Option B — install via npx (requires Node.js)
First check whether npx is available:
bash(command="which npx")If it is, install the skill. Select a single skill from a multi-skill repo with
the @<skill> suffix (omit it to take the whole repo):
bash(command="npx --yes skills add <owner/repo>@<skill-name> -y")The Skills CLI stages the skill (with its references/, assets/, and
scripts/ subdirs) under .agents/skills/<skill-name>/ — exactly where Horizon
loads skills from — so no move is needed. Just refresh:
load_skill(action="reload")The staged directory name MUST match the name: field in the SKILL.md
frontmatter — _load_skill_from_dir validates that and skips mismatched
skills.
Step 6 — confirm activation
After load_skill(action="reload") returns (look for the new skill in
loaded), tell the user:
The "<name>" skill is now installed. It will appear in your
<available_skills> catalog on the next turn.When no skills are found
- Acknowledge that no existing skill was found
- Offer to help directly using general capabilities
- Offer to write a custom skill for them:
bash(command="npx --yes skills init my-skill-name")Or skip the CLI and author one manually — write a SKILL.md following the
policy or workspace skills as examples.
