Create and delete custom managed skills in a workspace

  • User creates a new managed skill by scaffolding a YAML frontmatter file with a description.
  • This skill depends on user input for skill descriptions and directory creation.
  • It decides what to do based on the presence of valid `SKILL.md` files within the skill directories.
  • Results are delivered through the availability of invocable skills in the workspace.

      - "User wants to scaffold a new managed skill in their workspace from a description"
      - "User wants to delete or list the custom skills they have defined"
      - "User wants to author or edit a SKILL.md and have it become invocable as a skill"
    avoid-when:
      - "User just wants to use an existing skill — that is normal skill activation, not management"

Manage the lifecycle of custom managed skills in `{workspaceDir}/skills`.

## Capabilities

- **Scaffold** a new managed skill with YAML frontmatter and markdown body
- **Delete** an existing managed skill directory

Skills created via `scaffold_managed_skill` become available for `skill_load` when a valid top-level `SKILL.md` is written under the skill directory.

app-builderBuild and edit small, personal visual tools and artifacts — dashboards, trackers, calculators, data visualizations, charts, simple landing pages, and slide decks the user wants for THEMSELVES. This is the right skill whenever the user asks to "visualize this," "make a chart," or "build an artifact" for their own use, or to edit an app they already built here. Do NOT reach for a ui_show dynamic_page to fake an artifact — build a real persistent app here. NOT for complex, multi-user, or shippable products — those go to a real project folder with a coding agent (see Scope below).

Handles single-source and multi-source migrations with a unified, deduplicated inventory.

conversation-launcherOffer the user several spin-off conversations as clickable buttons on a single persistent card. Each click spawns a fresh seeded conversation in the sidebar; the user keeps their place in the current conversation. Use when you want to branch into N focused threads (research directions, draft choices, pending replies, triage of N items) without losing the current context. Not for single-destination pivots — just reply inline.
