Each skill is a folder of Markdown and\ncode; the app renders every skill's `SKILL.md` and gives you a one-click **Copy\nskill** button that puts a ready-to-run payload on your clipboard.\n\nA skill is **just a folder** — drop `skills//SKILL.md` in and it shows up.\nThere's also a **Slack \"Skills Librarian\"** bot (in `librarian/`) that can list,\nexplain, and CRUD skills by chat.\n\n🔗 **Catalog:** https://dcm31--92861134610211f1a0c51607ee4eb77e.web.val.run\n\n## How a skill is structured\n\nA skill is a folder under `skills//` following the standard Agent-Skills\nlayout, so it stays valid and discoverable by agents reading it outside this\napp:\n\n```\nskills//\n SKILL.md # entry point — what the skill does and the flow to follow\n scripts/ # runnable code the agent writes locally\n knowledge/ # reference docs the agent reads for context\n assets/ # optional HTML fragment, shown as a live example\n```\n\nOnly `SKILL.md` is required. Its YAML frontmatter is the skill's metadata.\n\n```markdown\n---\nname: PR Summarizer\ndescription: Reads a GitHub PR diff and writes a release note. Use when…\ncategory: Engineering\n---\n\n# PR Summarizer\n\n…the instructions an agent follows…\n```\n\nThe catalog is derived at request time: the app lists `skills/*`, reads each\n`SKILL.md`'s frontmatter for `name` / `description` / `category`, and collects\nthe folder's files. Add a folder → it appears. Edit frontmatter → the card\nupdates. (`name` falls back to a title-cased slug, `category` to\n\"Uncategorized\", if you omit them.)\n\n## Managing skills\n\nThree ways, in increasing convenience:\n\n1. **The Slack Skills Librarian** (see below) — \"list the skills\", \"how does X\n work\", \"create a skill that…\", \"change the UI skill to…\".\n2. **A coding agent** via the Val Town plugin (Claude Code / Codex / Cursor):\n `npx plugins add val-town/plugins`, then ask it to add or edit a skill.\n3. **By hand** in the Val Town editor — a skill's body is plain Markdown, so a\n typo fix is a two-second edit that deploys on save.\n\n## The Slack Skills Librarian (`librarian/`)\n\nA Slack agent (Claude + the Vercel AI SDK, built on the `templates/ai-slackbot`\nquickstart) that manages this library through a small set of structured tools.\nThe design split: **reads are broad, writes are deliberate.**\n\n| Tool | What it does |\n| -------------------------------- | ----------------------------------------------------------------- |\n| `list_skills` | Lightweight catalog (name / category / description) |\n| `read_skill` / `read_skill_file` | Read a skill's SKILL.md or a supporting file |\n| `create_skill` | New skill — writes the folder + SKILL.md with correct frontmatter |\n| `update_skill` | Change metadata, body, or one file of an existing skill |\n| `delete_skill` | Remove a skill (guarded by an explicit `confirm`) |\n\n`create_skill` / `update_skill` own the folder-and-frontmatter shape, so the bot\ncan't produce a malformed skill, and every write is scoped to this val's\n`skills/` folder. Reads use `std/utils` (token-free); writes use the Val Town\nREST API with a token (`VALTOWN_TOKEN`) and target the **current branch**, so on\nthe `librarian` branch new skills land on the branch until you merge to `main`.\n\n### Setup\n\n1. Open the bot's HTTP endpoint (the `librarian/events.ts` file's URL) and click\n **Create Slack App →** — scopes, events, and the webhook URL are pre-filled\n from a manifest.\n2. Give the bot its face: Slack manifests can't carry an icon, so upload the\n owl (served at the endpoint's `/icon.png`) under the app's **Basic\n Information → Display Information**. Replies wear the owl automatically via\n `chat:write.customize` either way; the upload covers everything else (DM\n list, Assistant pane, app home).\n3. Install the app to your workspace, then set these environment variables on\n this val:\n - `SLACK_BOT_TOKEN`, `SLACK_SIGNING_SECRET` — from the Slack app\n - `ANTHROPIC_API_KEY` — for the model\n - `SLACK_APP_ID` _(optional)_ — powers the catalog toolbar's \"DM the\n librarian\" link\n4. **Authorize Val Town writes** with one click on the `/connect` page (the\n `librarian/connect.ts` endpoint — also surfaced from the catalog's bottom\n bar). That stores a self-refreshing OAuth token so the librarian can create &\n edit skills. No API token to create or paste.\n5. Message the bot in its Assistant tab or `@mention` it in a channel.\n\n> Prefer a token over OAuth (or running headless)? Set `VALTOWN_TOKEN` to a Val\n> Town API token with val write access and the librarian uses that instead — it\n> takes priority. Either way, only the skill-CRUD tools touch it.\n\n---\n\n## Live examples\n\nA skill can ship a live preview — a working UI rendered right on its page. Drop\nan HTML fragment in the skill's `assets/` folder (e.g. `assets/showcase.html`)\nand reference it from `SKILL.md` with a Markdown link. The app renders the first\n`assets/*.html` it finds as an **Examples** panel, and serves it standalone\n(iframe-embeddable) at `/skills//example`. The **ui-example** skill ships\none and walks through the feature.\n\n## Technical details\n\n### Files\n\n```\nhttp.tsx # public catalog routes\nlib/skills.ts # skill discovery (folder → catalog), file + copy-payload helpers, frontmatter parse\nlib/vt.ts # Val Town REST client: skill writes + a catalog read-list fallback\nog.ts # social card image\ncomponents/ # Layout, Home, SkillDetail, FileView, FileTree\nfrontend/client.js # clipboard wiring for [data-copy] buttons\nskills// # the skills themselves (source of truth)\nlibrarian/ # the Slack Skills Librarian bot\n events.ts # HTTP entry: setup page + /icon.png + Slack /events + /process\n generate-response.ts # the agent loop (Claude + tools)\n icon.ts # the owl avatar (embedded base64 PNG)\n skill-tools.ts # list / read / create / update / delete tools\n slack-utils.ts # Slack client, verification, thread reconstruction\n handle-*.ts # app_mention / message / thread_started handlers\n prompt.md # librarian system prompt\n```\n\n### Catalog routes\n\n| Route | Purpose |\n| ---------------------------------- | --------------------------------------------------------------- |\n| `/` | Home — grid of skill cards |\n| `/skills/:slug` | Skill detail — rendered `SKILL.md`, Copy button, file tree |\n| `/skills/:slug/example` | Standalone live example (when a skill ships an `assets/*.html`) |\n| `/skills/:slug/files/*` | Raw file viewer |\n| `/client.js`, `/source`, `/og.png` | Clipboard JS, source redirect, social card |\n\n### Gating it to your team\n\nBy default the catalog is public. To restrict it to a Val Town org, sign\nrequests through `std/oauth` and check the signed-in user against your org's\nmembers (wrap the `http.tsx` `fetch` export with the OAuth middleware).

Scroll up: the **Examples** panel above this text is rendered live from the HTML fragment this skill ships.\n\n## What you're looking at\n\nA skill can ship a single HTML fragment under its `assets/` directory.
