feat: generic skills + split skills/design-templates + finalize-design API (#955)
* feat: general-purpose skills with @-mention composition and user import

Lift skills from "one mode-bound skill per project" to a generic capability
the user can compose per turn:

- Daemon: scan multiple skill roots (user-skills under runtime data, then
  the bundled `skills/`); user-imported skills can shadow built-ins by id.
- New `POST /api/skills/import` and `DELETE /api/skills/:id` endpoints,
  with CONFLICT/BAD_REQUEST/NOT_FOUND error codes and built-in delete
  protection.
- ChatRequest gains `skillIds: string[]`; the chat run concatenates each
  picked skill's body (and merges craftRequires) into the system prompt
  for that turn only — the project's persistent `skillId` is untouched.
- Web composer: `@` popover now lists skills alongside project files;
  picks render as removable chips above the textarea and ride along with
  the request as `skillIds`.
- Settings → Library: import form (name/description/triggers/body),
  per-card delete for user skills, "user" origin badge.

* chore(web): drop welcome pet teaser + add ds→prompt-template mapping util

- SettingsDialog: remove the inline pet adoption teaser from the welcome
  panel so the first-run modal stays focused on configuration.
- New `inferPromptTemplateCategoriesForDs(ds)` helper that maps a design
  system's authored metadata to prompt-template gallery categories.
  Imported by the design-system gallery wiring on a sibling branch; no
  callers in this branch yet.

* feat: split skills/design-templates and add finalize-design API

Phase 0 of the skills/design-templates refactor (specs/current/
skills-and-design-templates.md):

- Move ~104 rendering catalogue entries from skills/ to design-templates/
  and keep skills/ for the small set of functional skills that *do work*
  on user input (utilities, briefs, packagers).
- Add design-templates/AGENTS.md and skills/AGENTS.md describing the
  contract, and a brand-agnostic craft/ surface for opt-in craft rules.
- Daemon: add DESIGN_TEMPLATES_DIR / USER_DESIGN_TEMPLATES_DIR roots and
  an /api/design-templates surface mirroring /api/skills. Asset/example
  routes still span both registries so existing srcdoc URLs keep
  resolving across the rename.
- Web: split LibrarySection into SkillsSection + DesignSystemsSection,
  rename the EntryView "Examples" tab to "Templates", and update locales
  + the New-project picker accordingly.

Adds the finalize-design endpoint:

- New apps/daemon/src/finalize-design.ts and packages/contracts/src/api/
  finalize.ts — one-shot synthesis of a project's transcript + active
  design system + current artifact into <projectDir>/DESIGN.md via the
  Anthropic Messages API. Per-project .finalize.lock mirrors the
  transcript-export hygiene from PR #493; provider credentials are not
  persisted by the daemon.

Other supporting changes:

- README + AGENTS.md updates to document the new directory split and
  craft/ surface, plus i18n strings across 13 locales.
- Test refactors and new coverage (finalize-design, runs, sidecar
  server, plus refreshed daemon integration tests).
- .gitignore: scope the *.exe ignore to /OpenDesign.exe so legitimate
  vendor binaries are no longer hidden.

* fix(merge): move clinical-case-report to design-templates/

Origin/main added the clinical-case-report skill under skills/ before
the skills/design-templates split landed. Its od.mode is prototype, so
per specs/current/skills-and-design-templates.md it is a design template
and belongs alongside the other rendering catalogue entries — not under
the slimmed-down functional skills/ root. Moving it keeps the EntryView
Templates tab consistent with origin/main's intent.

* feat(skills): curated design/creative catalogue + collapsible Settings rows

Seed ~100 curated design/creative skill stubs under skills/ sourced from
awesome-claude-skills (ComposioHQ) and awesome-agent-skills (VoltAgent).
Each stub carries an od.category tag so the new filter pill row in
Settings -> Skills can group them. The seed script
(scripts/seed-curated-design-skills.ts, pnpm seed:curated-design-skills)
is idempotent: it only creates folders that don't already exist, so
hand-edited stubs are never overwritten.

- Daemon: parse and surface od.category on SkillInfo with a strict slug
  normaliser; mirror the field on SkillSummary in @open-design/contracts.
  Category is purely a UI hint — system-prompt composition is unchanged.
- Web: rewrite SkillsSection from a left-list / right-detail grid into a
  vertical stack of collapsible rows mirroring the External MCP panel
  (header always visible with name + mode/source/category pills + per-row
  enable toggle; SKILL.md preview, file tree and inline edit form expand
  on demand). Add a Category filter row above the list. Reorder Settings
  nav so Skills + External MCP sit above the Composio/MCP cluster. Update
  composer placeholder/hint across 17 locales to advertise '@ files or
  skills · / for commands'.
- Docs: extend skills/AGENTS.md with the curated catalogue rules
  (idempotency, category vocabulary, no upstream vendoring).

* test(skills): teach localized-content + system-prompt tests about the skills/design-templates split

mrcfps blocking review on PR #955: the skills/design-templates split
(b5993385) moved ~110 SKILL.md entries out of `skills/` and into
`design-templates/`, but two repo-level tests still hard-coded the
single-root layout, so CI gates went red on the merged branch:

- `e2e/tests/localized-content.test.ts` only scanned `<repo>/skills`
  while the locale `skillCopy` map keeps id-keyed entries spanning
  both roots (ExamplesTab/Templates uses one lookup regardless of
  origin). Teach the helper to read both `skills/` and
  `design-templates/`, deduplicating ids so the union matches the
  localized claim.
- `apps/daemon/tests/prompts/system.test.ts` read
  `skills/live-artifact/SKILL.md`, which now lives under
  `design-templates/live-artifact/`. Update the absolute path so
  composeSystemPrompt's coverage of the live-artifact preamble is
  exercised again.

Also enroll the curated design/creative catalogue (PR #955, ~91
stubs sourced from awesome-claude-skills / awesome-agent-skills) in
the DE / FR / RU `_SKILL_IDS_WITH_EN_FALLBACK` lists. The stubs are
English-only by design (frontmatter advertises an upstream URL); the
fallback list is exactly the place to acknowledge "we know this id
exists, English copy is fine here" so the localized-content coverage
gate passes without forcing a translation task per locale.

* fix(skills): always quote frontmatter name so importUserSkill round-trips numeric / boolean ids

mrcfps PR #955 review: `buildSkillMarkdown` emitted `name:
${escapeYamlString(name)}` without quotes, so YAML coerced names
like `123`, `true`, `false`, or `null` into non-string scalars on
re-parse. listSkills() then read `data.name` as a number/boolean
and the import flow's follow-up `findSkillById(skills, result.id)`
missed it, falling into `/api/skills/import`'s "imported skill
could not be re-read" 500 path for those ids.

Switch the emitter to a quoted scalar (`name: "..."`) — the
double-escape already in `escapeYamlString` makes the quoted form
safe — and add a round-trip test covering `123`, `true`, `false`,
`null`, and `0` to lock in the contract.

* fix(web): drop staged-skill chips when the matching @<id> token leaves the draft

mrcfps PR #955 review: `submit()` always forwarded every id in
`stagedSkills`, but that state was only mutated on picker click and
chip removal. Hand-deleting an `@<id>` token from the textarea left
the chip staged, so the request still carried `skillIds: [<id>]` and
the daemon composed a skill the prompt no longer referenced.

Sync the chips with the draft inside `handleChange()` by pruning
`stagedSkills` whenever the new value no longer contains the
`@<id>` token (using the same whitespace boundary as
`removeStagedSkill`'s strip regex). Comment explains why this
prune does not run for `staged` file attachments — users frequently
add files via the upload button without leaving an `@<path>` token,
so a symmetric prune there would erase legitimate uploads.

* fix(daemon): stage @-composed skills' side files alongside the active skill

codex PR #955 review: composing a per-turn `@`-picked skill into the
system prompt appended its body (with the `withSkillRootPreamble`
guidance pointing at relative paths under `<cwd>/.od-skills/<folder>/`)
but never staged the actual folder. `startChatRun` only copied
`activeSkillDir`, so when the project's primary skill was different
(or absent) the composed skill's references/, examples/, and scripts/
files lived only at their absolute repo path — agents that honour
the cwd-relative form (or that don't get `--add-dir`, e.g. Codex with
allowlisted gpt-image projects) couldn't reach them.

Thread the composed skills' dirs out of `composeDaemonSystemPrompt`
as `extraSkillDirs` and stage each one through the same
`stageActiveSkill` API used for the primary skill. Dedupe by folder
basename so a project whose primary skill is also `@`-composed isn't
copied twice. Each preamble already advertises its own folder, so the
prompt and the staged tree stay aligned without further changes.

* fix(web): respect the Library disable toggle in the project @-mention picker

codex PR #955 review: only `EntryView` received `enabledSkills`
(filtered against `config.disabledSkills`); active projects still
got `skills={skills}` raw, so a skill the user disabled in Settings
kept appearing in the project's `@`-mention popover and could ride
along to the daemon via `skillIds`. That broke the Library toggle
for any project opened on the post-split branch.

Compute a functional-skills-only enabled subset
(`enabledFunctionalSkills`) and pass it into `<ProjectView>` instead.
Templates stay separate — design-templates are filtered through their
own `enabledDesignTemplates` memo for the Templates gallery — so
ProjectView's chat composer still only sees skills, never templates,
matching the pre-split prop surface.

* test(e2e): mock /api/design-templates for example-use-prompt flow

The Templates tab in EntryView fetches from /api/design-templates after
the skills/design-templates split (specs/current/skills-and-design-templates.md).
The example-use-prompt Playwright scenario only mocked /api/skills, so the
gallery card never appeared and the test timed out waiting on
example-card-warm-utility-example. Serve the same fixture summary on both
endpoints so the templates gallery renders the card the test clicks.

* test(tools-pack): create design-templates fixture for resources test

The packaging resources copy now bundles the new design-templates tree
alongside skills (see resources.ts BUNDLED_RESOURCE_TREES). The
copyBundledResourceTrees fixture only created skills, design-systems,
craft, etc., so the recursive copy crashed with ENOENT on
design-templates before it could check the prompt-templates assertion.
Add the missing fixture directory so the test exercises the same set
of resource trees the packaged build does.

* fix(skills): clone built-in side files into the shadow on first edit

mrcfps PR #955 review: editing a built-in skill wrote a USER_SKILLS_DIR
shadow folder that contained only a new SKILL.md. The next listSkills()
pass surfaced the shadow as the active dir, but every side-file resolver
(/api/skills/:id/files, /example, /assets/*, the system-prompt preamble,
and the per-turn cwd staging) reads through skill.dir. With nothing but
SKILL.md in the shadow, the bundled assets/, references/, scripts/, and
examples/ disappeared the moment the user hit save — a built-in like
last30days or live-artifact would break immediately after edit instead
of just having its body overridden.

Teach updateUserSkill() to take a `sourceDir` and clone every entry
except SKILL.md / dotfiles into the shadow on the very first edit. The
shadow stays self-contained, so all the resolvers keep working without
fallback bookkeeping. Subsequent edits detect the existing shadow and
skip the clone, so user tweaks under the side tree survive a re-save.

Wire `sourceDir: skill.dir` from server.ts's PUT /api/skills/:id handler
and add two regression tests:
- 'clones built-in side files into the shadow on the first edit' walks
  the file tree after save and asserts assets/template.html, references/
  notes.md, and scripts/helper.sh all round-trip from the built-in.
- 'preserves user-edited side files on subsequent edits' edits the
  staged assets/template.html, re-saves, and confirms the user content
  is still there.

* test(e2e): rename home tab from Examples to Templates

The Examples tab was renamed to Templates in EntryView (b5993385's
skills/design-templates split — entry.tabExamples became entry.tabTemplates
and the tab value moved from 'examples' to 'templates'), but
entry-chrome-flows still asserted the old label and testId. Update both.

* fix(skills+web): preserve template body in API mode and dir-based skill delete

Two follow-ups from PR #955 review:

1. ProjectView only received `enabledFunctionalSkills`, but
   `composedSystemPrompt()` still resolved `project.skillId` through that
   prop and `fetchSkill()`. Projects created from the new
   `/api/design-templates` surface keep a template id in `project.skillId`,
   so opening one in API mode dropped the template body from the system
   prompt and the upstream request ran without the project's primary
   template instructions. Now ProjectView takes a separate
   `designTemplates` prop (the unfiltered template list, so a
   later-disabled template still loads for projects already created from
   it) and `composedSystemPrompt()` plus the metadata / `isDeck` lookups
   fall back to that list, with `fetchDesignTemplate()` as the body-fetch
   fallback to `fetchSkill()`. The chat composer's `@`-picker keeps
   receiving only the enabled functional skills.

2. `DELETE /api/skills/:id` used `deleteUserSkill(USER_SKILLS_DIR, skill.id)`
   which re-slugified the frontmatter id and removed
   `<userSkillsDir>/<slug>/`. That matched the import shape but missed the
   install shape — `installFromTarget` writes the folder at
   `sanitizeRepoName(url)` (GitHub) or `path.basename(realpath)` (local
   symlink), neither of which is guaranteed to equal the slugified
   frontmatter `name`. A duplicate `app.delete('/api/skills/:id', ...)`
   handler at the install routes never fired because Express resolved the
   earlier registration first, leaving the install/uninstall path without
   working teardown. The handler now removes `skill.dir` (the absolute
   path listSkills already discovered) under a USER_SKILLS_DIR safety
   check, using `lstat` + `unlinkSync` so symlinked local installs unlink
   cleanly without recursing into the user's source tree. The dead
   duplicate handler is removed; `deleteUserSkill` is dropped from the
   server.ts import set (still exported and unit-tested in skills.ts).
   Regression coverage in `apps/daemon/tests/skills-delete-route.test.ts`
   pins both shapes plus the symlink-preserves-source case.

* test(daemon): point hyperframes system-prompt test at design-templates

The merge with main brought in a hyperframes system-prompt test that
reads `skills/hyperframes/SKILL.md`, but this branch's split moved
`hyperframes` into `design-templates/` (same migration as `live-artifact`
already handled above in this file). CI was failing with ENOENT on the
old path.

tools/pack

Local packaging control plane for Open Design.

The active slice is mac-first local packaging and smoke lifecycle control:

  • tools-pack mac build --to all
  • tools-pack mac build --to app|dmg|zip
  • tools-pack mac build --to all --signed
  • tools-pack mac build --to all --portable for release artifacts that must not bake local tools-pack runtime paths
  • tools-pack mac install
  • tools-pack mac start
  • tools-pack mac stop
  • tools-pack mac logs
  • tools-pack mac uninstall
  • tools-pack mac cleanup

Build artifacts are namespace-scoped under .tmp/tools-pack/out/mac/namespaces/<namespace>/. Release artifacts keep the canonical Open Design.app bundle shape; local tools-pack install copies it as Open Design.<namespace>.app so developer namespaces can coexist without affecting runtime data/log/cache paths.

Packaged runtime state is namespace-scoped under .tmp/tools-pack/runtime/mac/namespaces/<namespace>/:

  • data/ is the daemon-managed data root passed to the daemon through the packaged sidecar launch environment.
  • logs/ contains packaged process logs for desktop, web, and daemon.
  • runtime/ is the sidecar runtime base used by the packaged desktop/web/daemon process group.
  • cache/ is reserved for namespace-local packaged cache state.
  • user-data/ is the Electron/Chromium userData root, with user-data/session/ used for sessionData.

Finder/manual launches cannot carry argv stamps on the root desktop process. To keep process fallback safe, apps/packaged writes runtime/desktop-root.json with the desktop stamp, PID, executable path, app path, and log path. tools-pack mac stop trusts that marker only when namespace/stamp/PID/command validation passes; otherwise it reports the unmanaged/not-owned reason instead of killing unknown processes.

tools-pack mac stop validation

  • If the marker is absent, stop reports not-running.
  • If the marker PID is gone, stop reports not-running and clears the stale marker.
  • If the marker PID was reused by an unrelated process, stop reports unmanaged.
  • If the marker namespace, stamp, runtime root, or command does not match the current namespace, stop reports unmanaged.

This keeps stop from killing processes outside the current namespace.

Packaged desktop also writes main-process lifecycle logs to logs/desktop/latest.log so Finder/manual launches are diagnosable. This log is intentionally scoped to packaged desktop startup/shutdown/process errors and does not capture web/renderer console output.

The packaged daemon path contract is explicit: tools-pack writes namespace/base config, apps/packaged resolves namespace paths, and the packaged sidecar launcher passes daemon managed paths via launch env. The daemon may keep its own default fallback for non-packaged launches, but packaged runtime must not rely on fallback inference from Electron userData, app bundle names, or ports.

Runtime updater integration remains a later phase.

Electron-builder resources live under tools/pack/resources/mac/. The current logo is staged there as the mac icon/DMG placeholder so future design-provided assets can replace the resource files without changing packaging code.

Local developer artifacts bake the tools-pack namespace runtime root so tools-pack mac start/stop/logs/cleanup can manage them from the repo. Release artifacts use --portable so the installed app resolves namespace data/log/runtime/user-data from the user's Electron userData root instead of the build machine's .tmp path.

Windows

Local lifecycle commands:

  • tools-pack win build --to dir for fast unpacked smoke builds.
  • tools-pack win build --to nsis for installer builds.
  • tools-pack win build --to all for both outputs.
  • tools-pack win install
  • tools-pack win start
  • tools-pack win inspect --expr "document.title"
  • tools-pack win logs
  • tools-pack win stop
  • tools-pack win cleanup
  • tools-pack win list
  • tools-pack win reset

Build artifacts are namespace-scoped under .tmp/tools-pack/out/win/namespaces/<namespace>/. Packaged runtime state is namespace-scoped under .tmp/tools-pack/runtime/win/namespaces/<namespace>/. --to dir may point built-app.json at an immutable cached win-unpacked executable while keeping namespace-local config and runtime paths outside that cache entry.

Linux

Local lifecycle commands:

  • tools-pack linux build --to all (default; produces AppImage)
  • tools-pack linux build --to appimage (explicit AppImage)
  • tools-pack linux build --to dir (unpacked output for fast iteration)
  • tools-pack linux build --containerized (run electron-builder inside electronuserland/builder:base Docker for distro-agnostic glibc compat — requires Docker)
  • tools-pack linux build --to all --portable (release artifacts that must not bake local tools-pack runtime paths)
  • tools-pack linux install
  • tools-pack linux install --headless (install the headless launcher script instead of the AppImage)
  • tools-pack linux start
  • tools-pack linux start --headless (start the headless entry — daemon + web, no Electron)
  • tools-pack linux stop
  • tools-pack linux stop --headless (stop a running headless process)
  • tools-pack linux logs
  • tools-pack linux uninstall
  • tools-pack linux cleanup

Build artifacts are namespace-scoped under .tmp/tools-pack/out/linux/namespaces/<namespace>/. Packaged runtime state is namespace-scoped under .tmp/tools-pack/runtime/linux/namespaces/<namespace>/{data,logs,runtime,cache,user-data}/. Containerized build cache lives under .tmp/tools-pack/.docker-cache/{electron,electron-builder}/.

Local installs use XDG paths:

  • AppImage: ~/.local/bin/Open-Design.<namespace>.AppImage
  • Menu entry: ~/.local/share/applications/open-design-<namespace>.desktop
  • Icon: ~/.local/share/icons/hicolor/512x512/apps/open-design-<namespace>.png

The <namespace> suffix is unconditional so multiple developer namespaces can coexist on the same desktop. The .desktop file registers the od:// scheme via MimeType=x-scheme-handler/od; and pre-sets OD_PACKAGED_NAMESPACE on the Exec= line so menu launches identify the correct namespace.

Headless mode (--headless)

Headless mode targets environments without a display (WSL2, headless servers, CI) where Electron can't run. If you have a desktop, use the AppImage; if you're SSH'd into a machine or in WSL, use headless.

--headless makes install, start, and stop operate on the headless entry (@open-design/packaged/dist/headless.mjs) instead of the AppImage. Headless mode runs daemon + web without Electron.

  • install --headless writes a shell launcher at ~/.local/bin/open-design-headless-<namespace> that bakes in the namespace and resource paths. The launcher is self-contained, but the assembled app directory at those paths must remain in place — don't move it after install.
  • start --headless spawns the headless process directly, redirects stdout/stderr to logs/desktop/latest.log, and waits up to 95s (35s for identity marker + 60s for web URL) before returning.
  • stop --headless reads the same runtime/desktop-root.json identity marker as the AppImage path, validates stamp.source === PACKAGED, sends a graceful SHUTDOWN over IPC, then terminates the process tree. It does not perform the AppImage-specific process-command check.

logs always reads logs/desktop/latest.log regardless of mode, so headless output is visible via tools-pack linux logs.

AppImage launch mode (FUSE caveat)

tools-pack linux start always spawns the AppImage with --appimage-extract-and-run. Smoke testing on Ubuntu 24.04 and Arch Linux showed that direct FUSE-mounted AppImage launches make Node module loads (Express, better-sqlite3, etc.) slow enough that the daemon sidecar consistently failed to clear apps/packaged's 35-second startup timeout. Extract-and-run unpacks the AppImage into /tmp/appimage_extracted_<hex>/ and exec's the inner Electron from there, bypassing FUSE and getting daemon boot in under 5 seconds — roughly an order-of-magnitude improvement.

Implication for end-users: if launching the installed AppImage manually (not via tools-pack linux start), pass --appimage-extract-and-run yourself, or rely on a desktop launcher / appimage-launcher daemon that handles extract-and-run automatically.

Optional system tools

tools-pack linux install and tools-pack linux uninstall invoke update-desktop-database and gtk-update-icon-cache as best-effort post-hooks. Either tool being absent (iconCache: "missing" in the output) is harmless — the icon and menu entry still work, the cache just isn't refreshed. Install via your distro:

  • Arch / CachyOS: sudo pacman -S desktop-file-utils gtk-update-icon-cache
  • Debian / Ubuntu: sudo apt install desktop-file-utils gtk-update-icon-cache
  • Fedora: sudo dnf install desktop-file-utils gtk-update-icon-cache

libfuse2 is needed for FUSE-mounted AppImage launch (the default mode when running an AppImage directly without --appimage-extract-and-run). tools-pack linux start always uses extract-and-run and bypasses FUSE entirely, so it does not need libfuse2. Most modern distros ship libfuse2 by default; older Ubuntu LTS hosts may need sudo apt install libfuse2t64 (or libfuse2 on pre-24.04).

Sandbox / chrome-sandbox

Electron 41 on Linux requires kernel.unprivileged_userns_clone=1 (default on Arch, Ubuntu 24+, Debian 12+) or AppImage's --no-sandbox fallback. Most modern distros need no extra setup.

Distro-agnostic guarantee

AppImages built natively on a rolling distro (e.g., Arch / CachyOS) link against recent glibc and may not run on stable distros (Ubuntu 22.04, Debian 12). Use --containerized to build against the wide-compat electronuserland/builder:base baseline (Ubuntu 18.04 / glibc 2.27).

Format choice: why AppImage first

Linux desktop apps in this space split across formats: VS Code ships .deb + .rpm + Snap; Discord ships AppImage + .deb; Slack ships .deb + .rpm; Cursor and Obsidian ship AppImage. We start with AppImage because it is universal (one artifact runs on any glibc-compatible distro), needs no repo plumbing, and integrates cleanly with the namespace-scoped install layout. .deb / .rpm / Snap / Flatpak can land incrementally if user demand surfaces.

Out of scope (later phases)

  • AppImage signing (--signed) — deferred pending a GPG key infrastructure decision and a user-facing verification flow design (no ETA).
  • AppImage auto-update feed (latest-linux.yml) — the linux electron-builder config has no publish block wired, so a generated feed would point users at a feed that never updates. Tracked alongside signing.
  • Additional package formats: .deb, .rpm, Snap, Flatpak.
  • Linux entry in ci.yml (release lanes only build linux; PR validation does not yet).

--to dmg is manual-install DMG output only. Any builder-generated updater metadata such as latest-mac.yml or .blockmap files is treated as scratch and cleaned from the builder directory; release-beta generates the authoritative latest-mac.yml feed during release asset preparation, pointing at the update ZIP.
