Import Skill

Import a skill

Turn what the guardian brings you into something installed — a URL to an existing skill, a pasted SKILL.md, or a description of one they wish existed. Brainstorm with them: propose, listen, revise. Don't install anything without getting a clear go-ahead.

Most of what you're handed is a plain skill for the user-skills carrier. The involved ones — a setup step, real interaction, a multi-step process — are better off as their own app. Sorting which is which, with the guardian, is part of the job: see "Skill, or a dedicated app?" before you install.

Classify the input

• URL → see "Resolving a URL".
• Pasted SKILL.md (frontmatter + body, or close to it) → validate, preview.
• Description (prose, a wish, a workflow explained) → see "Generating".
• Empty or ambiguous → ask one short question. Don't guess.

Resolving a URL

• github.com/<owner>/<repo>/blob/<ref>/<path> → fetch the raw form https://raw.githubusercontent.com/<owner>/<repo>/<ref>/<path>.
• github.com/<owner>/<repo>/tree/<ref>/<dir> → list it via https://api.github.com/repos/<owner>/<repo>/contents/<dir>?ref=<ref> and download the SKILL.md plus its auxiliary files.
• Bare repo → look for SKILL.md at the root, then under skills/.
• Anything else → fetch it; if it's skill-shaped, proceed; if it's prose describing a workflow, offer to generate a skill from it.

If the source holds more than one skill (several SKILL.md under skills/, a repo of them, a page linking many), don't pick for the guardian: list each one you found — path, name, and description — and ask which to import. They may choose one, some, or all; import each as its own pass through the rest of this flow (validate → preview → install), so every skill gets its own confirmation.

On a network error or 404, say so and ask for a corrected link.

Generating from a description

The guardian is the domain expert; you're the author. Ask at most 2–3 focused questions, only where the description is genuinely open:

• Trigger — when should an agent reach for this? (Becomes the description line, which is also the search index.)
• Procedure — the concrete steps, commands, decision points. "Check the logs" isn't an instruction; "run X and look for Y" is.
• Tools — which built-ins the steps need.
• Boundaries — what it should refuse or hand off.

Draft the SKILL.md yourself and preview it. The body is second-person, imperative, concrete — instructions for a future agent, not human docs.

Skill, or a dedicated app? Decide before you install

A skill is pure instructions an agent reads. Some requests are apps wearing a SKILL.md, and the carrier gives them a worse version of what they asked for. Once you understand the request, judge it. App-shaped signals — any one means it wants to be its own app:

• an init / setup step before it's usable (credentials, first-run config);
• it needs to interact — ask and react, not just run top-to-bottom;
• a real multi-step process, its own data / operations / UI, or background / scheduled execution.

A shell command or two inside otherwise-pure instructions is still a skill. When the signals are real, put the choice to the guardian — don't pick for them:

• Import as a skill → the user-skills carrier (the flow below).
• Build a dedicated app → a brand-new app of its own, friendly and interactive.

Only continue into validate/preview/install when they choose the skill.

Building a dedicated app

Read the coding:app_creation skill with read_skill and follow it to scaffold, build, and install a brand-new app — its OWN app id, never user-skills or the carrier. Carry what you've learned from the guardian as the brief: what the thing does, its init/setup step, the interactions it needs.

Design a friendly flow: an init step that gets the guardian set up, interaction that guides rather than dumps questions, and — where it fits — a conversational agent they talk to, with the app's entry dropping straight into that chat. (A pure inputs → steps → result automation isn't an app — coding:app_creation will redirect it to coding:workflow_creation, as it should.)

Validate against Rome's parser

Rome parses frontmatter with regexes, not YAML. A violating skill installs but is silently dropped from the catalog. Enforce on every skill:

1. Starts with a --- line and has a closing ---.
2. name: is a single lowercase kebab-case line matching the install folder.
3. description: is a single line — collapse folded (>) or multi-line ones.
4. tools: is only read inline (tools: [A, B, C]) — convert dash-lists; drop one you can't convert and say so.
5. Other keys are ignored, harmless — keep them.

Auto-fix 2–4 and note each fix in the preview. Then check list_skills for a name collision (propose an alternative rather than shadow), and make sure the description carries the trigger words someone would search — search_skills matches name/description/tools, never the body.

Preview, then confirm

Show the guardian the complete final SKILL.md in a fenced block (and any auxiliary files), a note of every fix you made, and the install path user-skills/skills/<name>/. Ask, and wait. Anything short of a clear yes is feedback — revise and preview again.

Install into the carrier

Skills install into one carrier app, user-skills, at <custom app authoring directory from your Runtime Context>/user-skills (~/.rome/<profile>/projects/apps/user-skills).

If it doesn't exist, create it — a minimal hand-rolled layout, no build toolchain, so the coding:app_creation scaffold doesn't apply. It must ship a logo and a minimal web UI, or it shows up in the Apps list as a broken-looking entry. Write the files below exactly; the manifest is schema-validated (assetVersion 12 hex chars, routing: "client", entry exports mount). Backfill these into an existing carrier that's missing them.

  root.querySelector("#open-skills").addEventListener("click", (e) => {
    e.preventDefault();
    window.dispatchEvent(new CustomEvent("rome:host-navigate", { detail: { path: "/apps/skills" } }));
  });
}

Plus package.json: { "name": "user-skills", "private": true, "type": "module" } and an empty skills/ directory. If you later edit web/index.js, bump assetVersion to a new 12-hex string so the browser drops the cached bundle.

Then, for the confirmed skill:

1. Write skills/<name>/SKILL.md plus any auxiliary files.
2. Add skills/<name> to the skills: list in app.yaml.
3. git add -A && git commit -m "Add skill <name>".
4. Install: system:app_management with { "op": "install", "source": { "mode": "source", "path": "<carrier-abs-path>" } } — the daemon builds, packs, and installs in one step.

If a step fails, show the error, fix what you can, and say where things stand.

Verify

Call list_skills and confirm the new name is present. If it isn't, the catalog dropped it — almost always a frontmatter rule. Fix and re-install once; if it still doesn't appear, report what you tried. Once you've seen it listed, tell the guardian it's live: they can invoke it in any chat with /<name>, or find it in the Skills app.
