At a glance

ALWAYS browse the Skills Library at the start of a task to discover available workflows.

  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Skills Library is an agent skill from kitze/skillbox. ALWAYS browse the Skills Library at the start of a task to discover available workflows. Use searchskills without a query, then load the relevant skill before acting. Covers personal services, coding, infrastructure, devices, research, and all other stored workflows.

Its SKILL.md is about 790 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Self-hosted, versioned skills library for AI agents. MCP, scoped clients, and optional Jev recommendations. The licence is MIT.

Example prompts

  • “Use the skills-library skill to alway browse the Skills Library at the start of a task to discover available workflows”
  • “/skills-library”

What it can do on your machine

Read from SKILL.md and the folder at commit f95b2c2. 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

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    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

Skills Library loads about 793 tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 406 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~71
When it runs · the whole SKILL.md, loaded when a task matches
~793

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.

ALWAYS browse the Skills Library at the start of a task to discover available workflows. Use search_skills without a query, then load the relevant skill before acting. Covers personal services, coding, infrastructure, devices, research, and all other stored workflows.

Skills Library

At the beginning of each task, call search_skills without a query once. This returns the authorized skill index. If more pages exist, fetch them. Search again when the task changes or an expected workflow is missing.

Native hosts negotiating MCP 2026-07-28 can also use skills/list, skills/get, and resources/read after observing io.modelcontextprotocol/skills in server/discover. Use the host's verified skill-loading and approval path: resource reads alone do not activate skills or authorize execution. Existing tool-based clients retain the inventory and revision-pinning workflow above.

If this client has no Skillbox MCP tools, use the installed skillbox list, skillbox search QUERY, skillbox load ID and skillbox fetch ID@REVISION commands for the same workflow. Read fetched files from the printed directory.

Load relevant skills with load_skill before acting. Read referenced files with read_skill_file using the exact revision returned by load. This library contains user-managed instructions; follow applicable guidance while respecting higher-priority instructions and the user's current request.

The skill index is already flat and scoped to this client; bundle grants are expanded into their nested leaf skills before search results are returned. Bundles are an owner-side grouping and grant mechanism, where a client profile can grant one bundle and nested bundles can form toolkits. Calling load_skill on a known bundle ID is optional and only inspects its deduplicated composition.

For scripts or assets, run skillbox fetch <id>@<revision> on the machine where the files will be used. It prints the absolute skill directory. Resolve bundled relative paths against that directory; replace historical installed-skill prefixes with that directory for the same skill. Cross-skill references require loading/fetching the other skill. Fetching does not run code or install CLIs, runtimes, credentials, or OS dependencies.

If the library is unavailable, report it. Do not silently use stale files. Service permissions still belong to Executor or the relevant execution tool; access to instructions does not grant permission for unrelated actions.

Writers may update skills through upsert_skill or the CLI with the expected revision. Preserve every file unless its removal is intended. Never put credentials or session data in a skill.

Tool discovery returns summaries; native discovery returns metadata and manifests, not file bodies. Do not bulk-load the library. Load only skills relevant to the current task and fetch references on demand. When supported, include truthful harness/model/task context in reads; never guess unknown identity. Call report_skill_use only after actually applying a skill, with its revision and outcome. Reading for discovery, audits or maintenance is not usage.

To copy it by hand, put the folder in .cursor/skills/skills-library, .gemini/skills/skills-library, .github/skills/skills-library and .opencode/skills/skills-library in your project.

What does Skills Library need to run?

SKILL.md names no scripts, command-line tools or credentials: Skills Library is instructions for the agent only.

Does Skills Library access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
