Question: would you accept a PenguinHarness adapter contribution?

[shrekcg]

Hi maintainers — first of all, thanks for HarnessKit; managing 12 agents from one dashboard is great.

I'd like to use HarnessKit to manage PenguinHarness on my machine (it's a local agent harness that keeps multiple agent states under one data root). Right now it isn't among the supported agents, so I'm planning to add a penguin adapter, and wanted to ask before writing it whether that contribution would be welcome.

What PenguinHarness looks like on disk

<penguin-data-root>/
  agents/
    <agent_id>/
      agent_state/
        AGENTS.md
        skills/<skill-name>/SKILL.md
        memory/*.md
        schedule/ ...
        ...

Key points:

• One data root, multiple "agent states" (one per agent id) — structurally similar to how the dsh adapter handles multiple profiles under one home, so that pattern can be reused.
• Each agent state has its own AGENTS.md, skills/ (standard SKILL.md layout), memory/, etc.
• The harness itself is not a "big-name" CLI like Claude/Codex — same situation as dsh was before it got an adapter.

Proposed scope for a first contribution

• New adapter crates/hk-core/src/adapter/penguin.rs implementing AgentAdapter:
  • detect() checks the data root exists (also respect an env override, like DSH_HOME);
  • skill_dirs() enumerates agents/*/agent_state/skills;
  • config files: AGENTS.md / memory files tracked like other agents' global config files.
• MCP / plugin / hooks declared unsupported initially (Penguin's formats differ; can be added later, mirroring how some existing adapters started minimal).
• Follow CONTRIBUTING.md: build + tests green, update the capability matrix and AGENT_ORDER.

Questions

1. Would you be open to a penguin adapter contribution (or would you rather keep the supported list at the current 12)?
2. Any requirements for a new agent adapter beyond what CONTRIBUTING.md already asks for (docs, screenshots, verification against a real install, etc.)?

Happy to do the work — just want to confirm it's welcome before spending time on it. Thanks!
