Yaowei Zheng d4faee3a1e Changelog, dev startup, README, AgentHub 0.4.0, model catalog, and landing site (#7)
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.

Installation Install PenguinHarness via the install script, npm, or from source.

Requirements

  • Linux / macOS (x64 or arm64): the install script ships platform tarballs with an official Node.js runtime bundled — no local Node needed.
  • Other platforms, or installing via npm / from source: system Node.js >= 24.

On Linux / macOS:

curl -fsSL https://penguin.ooo/install.sh | sh

The script downloads the matching penguin-{linux,darwin}-{x64,arm64}.tar.gz, which bundles an official Node.js runtime. Other platforms do not fall back automatically: the script exits and asks you to install Node.js >= 24 and re-run with --universal, which selects the runtime-less penguin-universal.tar.gz.

Verify the install:

penguin -v

Install location and options

Item Details
Install dir ~/.penguin by default; override with the PENGUIN_INSTALL_DIR env var
Command entry A symlink ~/.local/bin/penguin is created (the script warns if ~/.local/bin is not on PATH)
Version pin PENGUIN_VERSION=vX.Y.Z env var, or the --version vX.Y.Z script flag; defaults to the latest Release
Integrity check Downloads are sha256-verified when the Release ships checksum assets
Upgrade Re-run the install script; files are swapped atomically

Script flags go after sh -s --, e.g. curl -fsSL https://penguin.ooo/install.sh | sh -s -- --universal.

Data directory

The data directory defaults to ~/.penguin/data — under the install home ~/.penguin, but never modified by install or upgrade — and is overridable with the PENGUIN_HOME env var. Model configuration, Session records, and other data are preserved across upgrades.

npm install

Requires system Node.js >= 24:

npm install -g @prismshadow/penguin-cli

The npm package is @prismshadow/penguin-cli; the installed command is penguin. Web UI assets ship inside the @prismshadow/penguin-server package, so this single install yields a working penguin web.

From source

Requires Node.js >= 24 and pnpm:

git clone https://github.com/Prism-Shadow/penguin-harness.git
cd penguin-harness
pnpm install && pnpm build

After the build, run pnpm penguin <args> inside the repo as the dev runner, or use the globally linked penguin command.
