skill-acquisition

skill-acquisition is a skill for Claude Code, Codex from tkellogg/open-strix. It costs 57 tokens per session (1,538 once invoked), scanned C, original, MIT.

A skill for finding, checking, installing, and packaging add-ons for AI agents. It works with public registries, command-line tools that include skills, and GitHub repositories.

In plain words
What is it for?
Use it to discover capabilities, install skills, or prepare a local skill for distribution.
Why use it?
It removes the need to search several sources and work out manually how to install or share an agent skill.

Skill for Claude CodeCodex

Which agent this was written for is unclear — built for openclaw. Also seen: built for openclaw.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is cp -r /tmp/skill-source/skills/<name> ./skills/<name>.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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.

ModelPer sessionOnce invoked
Fable 5.1 $0.00057 $0.01538
Opus 5.5 $0.00023 $0.00615
Sonnet 5.5 $0.00011 $0.00308
Haiku 4.5 $0.00006 $0.00154

Measured 1mo ago against content hash 1bd3c75d7a3a, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade C, and why

skill-acquisition scanned grade C 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 1mo 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.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

The opening of the file, as written. The whole thing — 199 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Skill Acquisition

You help users discover and install agent skills from the ecosystem. There are three main sources:

  1. ClawHub — Public skill registry (clawhub.ai) with vector search, versioning, and moderation
  2. Skillflag — CLI tools that bundle their own skills via --skill list/export
  3. GitHub/Raw — Skills as folders in git repos (SKILL.md + supporting files)

When to Use This Skill

USE when:

  • User asks to find/discover/search for skills or capabilities
  • User wants to install a skill from ClawHub or a CLI tool
  • User asks "is there a skill for X?"
  • User wants to package/publish a local skill
  • User asks about what skills are available

DON'T USE when:

  • User wants to CREATE a new skill from scratch (that's skill-creator)
  • User wants to modify an existing installed skill (just edit it)

Prerequisites

Both tools run via npx — no global install needed, just npm:

# ClawHub CLI (primary discovery tool)
npx clawhub --help

# Skillflag installer (for CLI-bundled skills)
npx skillflag --help

Discovery — Finding Skills

1. ClawHub Search (best for general discovery)

ClawHub uses vector search (OpenAI embeddings), so natural language queries work:

# Search by description
npx clawhub search "manage docker containers"
npx clawhub search "git workflow automation"

# Browse latest/trending
npx clawhub explore                          # newest 25
npx clawhub explore --sort trending          # trending now
npx clawhub explore --sort downloads         # most popular

# Machine-readable output
npx clawhub explore --json
npx clawhub search "kubernetes" --json

2. Skillflag Discovery (for CLI tools you already have)

Any skillflag-compliant CLI tool bundles its own skills:

# List skills a tool provides
<tool> --skill list

# See what a skill contains
<tool> --skill show <id>

# JSON metadata (includes digest for integrity)
<tool> --skill list --json

Known skillflag-compliant tools:

  • acpx — ACP coding agent delegation
  • Check any CLI you install: <tool> --skill list (won't break if unsupported)

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.

skill-acquisition is a skill published in the GitHub repository tkellogg/open-strix (93 stars, last pushed 2mo ago), licensed MIT. It adds 57 tokens to every session and 1,538 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
