14. Skills (Skill Library)
A Skill is a reusable package of methodology and expertise: it tells the Agent how to think about a class of work, what to check, and how to deliver. It is not a tool grant, and it does not expand which tools the Agent may call or bypass product governance.
Lantide uses the common Agent Skills package format (including a standard SKILL.md). The built-in Agent and external Agents connected over MCP can share the same skill definition; what they can actually do is still decided by Agent state, tool activation, MCP access mode, Approve, and audit.
14.1 What a Skill is (and is not)
| Is | Is not |
|---|---|
| Analysis / delivery methodology, checklists, quality rules, and reference resources | Extra API keys, database connections, or system privileges |
| On-demand guidance (progressive disclosure) | A way to obtain new tools or bypass Plan / Approve |
| A definition shareable with the built-in Agent and external Agents | A public marketplace or remote skill store |
Common misconception: importing a skill ≠ authorizing the Agent to do more. A skill only changes guidance on how to work; whether work is allowed remains under the existing governance layers.
14.2 Open Skill Library
- Click the Skill Library icon in the top-right of the main window.
- The dialog lists your imported personal (User) skills.
- For each skill you can toggle:
- Enabled: whether it is available to load in built-in chat
- Share with external agents: whether an external Agent connected over MCP may read the same definition
- Other actions: Import Skill…, Open Skills Folder, Validate again, and remove (deletes only Lantide’s managed copy; your original import folder is unchanged).
Built-in skills do not appear in this list. Product-built Plan / statistics / HTML methodology is managed by the app; Skill Library only manages packages you import. Executable scripts inside skills are not supported yet; packages with unsupported content show Scripts unsupported.
14.3 Import a skill
- Prepare a folder that follows the common format and contains a standard
SKILL.md. - In Skill Library, click Import Skill… and select that folder.
- After a successful import, use it in chat as
/skill-name(see §14.4).
If a managed skill with the same name already exists, import fails with a collision; remove or rename first, then retry. Use Validate again to re-check whether the package is still valid.
14.4 Explicit load with / in chat
In the right-hand AI chat input, type / to open the slash picker listing skills that are currently Enabled and slash-visible:
- Keep typing a name fragment to filter the list.
- Click with the mouse, or use Up/Down then Enter.
- When you send the message, the selected skill loads with that turn for the built-in Agent.
This is explicit load: you choose when to apply which methodology, instead of parking every skill in the system prompt.
14.5 Sharing with the built-in Agent and external Agents
| Consumer | How the skill is used |
|---|---|
| Built-in Agent | Skills Enabled in Skill Library; load explicitly with / in chat |
| External Agent (MCP) | The same managed definition; turn on Share with external agents, and the external connection remains bound by §13 access mode / scope |
The shared piece is the definition (how to work), not a raise of the external Agent’s privileges. Observe / Execute / Admin, Approve & Execute, Activity, and audit rules are unchanged.
14.6 Boundaries and limits
- Cannot bypass governance: skill instructions cannot bypass MCP access mode, Plan approval (Approve & Execute), audit, or artifact contracts.
- No marketplace: there is no public store, ratings, paid catalog, or remote registry; imports come from packages you pick on your machine.
- Third-party skills are not guaranteed drop-in: skills from other people or tools may need front-matter, path, or content adjustments before they validate and run in Lantide.
- Scripts not supported yet: packages with executable scripts do not gain execution capability; treat them as methodology docs and resources.
- Remove affects the managed copy only: the original import source folder is not deleted or modified.
