A skill finder and installer for agent skills, which are reusable instructions that extend what a coding agent can do.

Use it to search for skills, inspect likely options, install one from GitHub, or check and update installed skills.

It helps you locate an existing skill for a task instead of building that capability from scratch, and provides checks for adoption and source reputation.

find-skills — Skill for Claude Code and Codex by aspectrr

Install

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.

Any agent

npx skills add aspectrr/deer --skill find-skills

Clone the repo

git clone --depth 1 https://github.com/aspectrr/deer

Made for: Claude Code, Codex.

Per session 38 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

When invoked 587 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00038	$0.00587
Opus 5	$0.00019	$0.00293
Sonnet 5	$0.00008	$0.00117
Haiku 4.5	$0.00004	$0.00059

Measured 7d ago against content hash 054c2c3beaf3, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-07, from the pricing page.

Security

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 7d 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 — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Find Skills

Discover and install skills from the open agent skills ecosystem.

When to Use

User asks "how do I do X" where X might have an existing skill
User says "find a skill for X" or "is there a skill for X"
User wants to extend agent capabilities
User mentions needing help with a specific domain

Skills CLI

The Skills CLI (npx skills) is the package manager for agent skills:

npx skills find [query] - Search for skills
npx skills add <package> - Install a skill from GitHub
npx skills check - Check for updates
npx skills update - Update all installed skills

Browse skills at: https://skills.sh/

How to Help

Step 1: Understand the need

Identify the domain (React, testing, design, deployment), specific task, and whether a skill likely exists.

Step 2: Check leaderboard

Check https://skills.sh/ for well-known skills in the domain before searching.

Step 3: Search

npx skills find [query]

Step 4: Verify quality

Install count — Prefer 1K+ installs. Caution under 100.
Source reputation — Official sources (vercel-labs, anthropics, microsoft) are more trustworthy.
GitHub stars — Check the source repository.

Step 5: Present options

Show skill name, what it does, install count, source, and install command.

Step 6: Offer to install

npx skills add <owner/repo@skill> -g -y

Common Skill Categories

Category	Example Queries
Web Development	react, nextjs, typescript, css, tailwind
Testing	testing, jest, playwright, e2e
DevOps	deploy, docker, kubernetes, ci-cd
Documentation	docs, readme, changelog, api-docs
Code Quality	review, lint, refactor, best-practices
Design	ui, ux, design-system, accessibility

When No Skills Found

Acknowledge, offer to help directly, suggest creating a skill with npx skills init.

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.
