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.

| July 2026 updates: scheduled tasks, Agent snapshots and a stronger evaluation center | 2026-07-17 | changelog | Scheduled tasks, Agent State snapshots with export/import, benchmark scoreboards, the model identity principle and one-line install have all landed on main. |
This month a batch of updates directly serving "stable evolution" landed on main. Highlights below.
Scheduled tasks & Agent State snapshots
- Scheduled tasks: one TOML file per task under
agent_state/schedule/— cron-style scheduling keeps Agents working autonomously around the clock. - Agent State snapshots with export/import:
system_config.yamlcarries aversion; risky changes (optimization passes, import overwrite) snapshot tosnapshots/v<version>.tar.gzfirst, restore any time, with the live vault preserved.
Evaluation center
- Benchmark scoreboards: bundled suites, per-case scoring and trend curves; evaluations are charted per model, and each run deep-links to its Session's trace view.
- Evaluations carry the model: the model reference moved from benchmark_config onto each evaluation (
provider/model_idas a pair), making cross-model comparison direct.
Model system
- Model identity principle: a model is uniquely identified by the
(provider, model_id)pair; connection details live inline on the Project config entry, with client-resolved environment-variable fallback when the credential is left empty. - Custom provider groups: beyond built-in vendors and custom, users can create their own groups (OpenAI protocol by default, base URL required).
- Runtime baseline raised to Node ≥ 24: bundled runtime, CI and the release pipeline all migrated.
Install & experience
- One-line install: a repo-root
install.sh—curl | shdetects Linux / macOS and x64 / arm64; artifacts bundle the Node runtime, unpack and run. - Skill library revamp: Skills now use files as the runtime source of truth, with redesigned cards and quick invocation; built-in Agents converge to a single default_agent, with agent creation/optimization fully carried by the Skill library.
- Stability fixes: Gemini tool_call_id collisions on consecutive same-name calls, stream-view scroll jitter on short containers, and WorkGroup parallel tool timing are all fixed.
