What it does
Vellum Skills Catalog is an agent skill from vellum-ai/vellum-assistant. Discover bundled skills and search/install community skills from the skills.sh registry
Its SKILL.md is about 880 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Designed for Vellum personal assistants
The repository describes itself as: An AI Assistant that’s easy to setup, does your work 24/7, knows your preferences and gets better over time. The licence is MIT.
Example prompts
- “/vellum-skills-catalog”
Requirements
- Compatibility (from SKILL.md): Designed for Vellum personal assistants
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- User asks about capabilities - "Can you order food?" or "What can you do?"
- User wants a capability not covered by bundled skills - "Can you do X?"
- Skill has dependencies - if includes lists other skill IDs, load those first with skill_load
What it can do on your machine
Read from SKILL.md and the folder at commit 33cc983. 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 (its code samples are bash).
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.
Compatibility
Designed for Vellum personal assistants
From compatibility in the SKILL.md frontmatter.
Context cost
Vellum Skills Catalog loads about 884 tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 401 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.

You can help the user discover what skills are available and find community skills to extend the assistant's capabilities.
Bundled skills (first-party)
First-party skills are bundled with the assistant - they are compiled in and always available. They do not need to be installed or downloaded. To activate a bundled skill, use the skill_load tool:
skill_load skill=<skill-id>The skill catalog shown in the system prompt lists all bundled skills with their IDs. When a user asks about capabilities, refer to this list to find relevant bundled skills and load them as needed.
Community skills (skills.sh)
Community skills are published on the skills.sh registry and can be searched, inspected, and installed on demand using the assistant skills CLI.
Searching for community skills
assistant skills search "<query>"Returns matching skills with their slug, source, install counts, and security audit badges. Use this when the user asks for a capability not covered by bundled skills.
Installing a community skill
Trust model - check the source guardian before installing:
- Vellum-owned (
vellum-ai/*): First-party skills published by the Vellum team. Install these directly without prompting - they are vetted and trusted. - Third-party (any other guardian): Ask the user for permission first. Present the skill name, source, audit results, and install count. Say something like: "I found a community skill that could help, but it's published by a third party - we haven't vetted it. Want to install it anyway?"
assistant skills add <owner>/<repo>@<skill-name>For example:
assistant skills add vercel-labs/skills@find-skillsOnce installed, the skill appears in the workspace skills directory and can be loaded with skill_load like any other skill.

Typical flow
User asks about capabilities - "Can you order food?" or "What can you do?"
- Check the bundled skills list in the system prompt
- Present relevant skills to the user
- Load any that match with
skill_load
User wants a capability not covered by bundled skills - "Can you do X?"
- Search with
assistant skills search "<query>" - Present matching results with descriptions, install counts, and audit badges
- Check the source guardian to determine trust level (see trust model above)
- Install with
assistant skills add <owner>/<repo>@<skill-name> - Load it with
skill_load
- Search with
Skill has dependencies - if
includeslists other skill IDs, load those first withskill_load
Notes
- Bundled skills are always available and do not need installation
- Community skills are installed to the workspace skills directory
- After installing a community skill, it is auto-enabled and immediately loadable
- Skills can be enabled or disabled via feature flags without uninstalling them
- Never install third-party community skills without explicit user confirmation
