Skills

Your own procedures, surfaced as MCP prompts rather than tools, so a person selects one and a model cannot choose it for you.

Skills hold procedures you have written down: a release checklist, the way you file an expense, how you want a changelog worded.

A skill is a prompt, not a tool. That is the whole design. Your agent cannot read a skill's body and cannot choose one on your behalf. You invoke it, and MCP clients surface prompts as user-selected for exactly this reason.

Why not a tool

A tool is something a model picks when it judges the moment right. A procedure is something a person picks because they have decided this is the job.

If an agent could read every skill, it could shop the catalogue for its own instructions, which is a different system from the one you wrote a checklist for. So reading a skill's body sits in the author bundle, not the read one, and a profile granted invoke-only is offered no management tool at all.

What your agent can do

InvokeAuthor
any skill, as a promptskills.manage.list, skills.manage.get, skills.manage.write, skills.manage.remove

To keep an agent able to run your procedures but never to write one:

console
$ lanes link policy deny 'skills.manage.*' --profile personal --workspace local

From the CLI

console
$ lanes link skills list --profile personal --workspace local
$ lanes link skills show release-checklist --profile personal --workspace local
$ lanes link skills add ./release-checklist.md --profile personal --workspace local
$ lanes link skills remove release-checklist --profile personal --workspace local

A skill is a Markdown file with YAML frontmatter, and {{argument}} in the body is substituted when it is invoked.

Reconnect after adding one

A skill moves no counter. Adding a tool changes the advertised tool count, and that count is how you normally tell an agent is stale; a prompt changes nothing anyone can see.

So after lanes link skills add, reconnect your agent on the same reasoning you would for a new connection, without waiting for a number to change.

They belong to one profile

A skill you wrote under work is not available under personal. Nothing crosses.
