Serve "open in new tab" HTML previews from a separate origin (the loopback counterpart, or PENGUIN_PREVIEW_ORIGIN) with a signed, host-bound token, so localStorage/cookies/third-party embeds work while Agent-generated pages stay off the app origin. The app is canonicalized onto localhost and the preview host (127.0.0.1) serves only /preview/* — its /api answers 401 and app routes 302 to the canonical host — so the preview origin can neither set nor honor a session cookie.
Branch-length batch covering tooling, the model layer, the Web App and the public
surfaces. Highlights:
- Changelog: a per-release `changelog/<version>/` tree, grouped by the surface each
change touches, with a root CHANGELOG.md holding one line per release.
- Dev startup: `scripts/dev-prebuild.mjs` serializes the skills+core prebuild behind a
lock and keeps `pnpm install` current; `pnpm dev` runs server+web together.
- AgentHub 0.3.3 -> 0.4.0: OmniMessage complete payloads carry one opaque `fidelity`
object in place of item-level `signature`/`phase`, threaded verbatim through Trace,
replay and resume; malformed classification adapted to the new error types.
- Model layer: a model is always referenced by an explicit `(provider, model_id)` pair.
The provider is never inferred, guessed or defaulted -- both the catalog inference and
the unique-match config resolution are gone, and CLI, SDK, server routes and
run_subagent all require the complete pair. Catalog gains the Qwen Token Plan, Qwen
Pay-As-You-Go and Fireworks AI gateways, plus an expanded OpenRouter group.
- Web App: catalog preset sync and per-group speed test on the Models page, positional
slash commands, a markdown renderer, skill-library update reminders, and a vertically
centred draft page whose upward menus size themselves to the room available.
- Public surfaces: restructured READMEs, the penguin.ooo landing site and blog, refreshed
benchmark results for both suites, and the demo videos playing on the landing page.
Includes the fixes from a full review of the branch: 23 confirmed findings, among them a
provider-inference bug that could send one vendor's API key to another vendor's endpoint,
and an Escape handler that destroyed the composer's contents unrecoverably.
Verified on the branch head: pnpm test (1127 passing, 7 packages), pnpm typecheck and
pnpm format:check clean, Playwright e2e 14/14.
- make the docs brand link return to the landing site
- keep landing navigation active state synchronized across routes and section links
- tighten sticky-header anchor scroll spacing
Initial import of all source code, config, and README assets: the
packages workspace (cli, core, server, web, docs, landing, skills),
build scripts, tooling config, and CI workflows.
Includes the data-layout revision made on this branch: the local data
root defaults to ~/.penguin/data (PENGUIN_HOME still overrides; the
installer keeps its binaries in ~/.penguin), and every Agent lives
under <project>/agents/<agent>/ — path helpers, the three
agent-enumeration scans, the system prompt, built-in Skills, tests
and docs all follow the new layout.
