copass-hermes-agents

Copass agent primitives for the Hermes API server (NousResearch hermes-agent), routed to LLMs via OpenRouter.

This package owns the Hermes-specific backend and the CopassHermesAgent(BaseAgent) convenience subclass. Hermes itself runs inside a per-(user, sandbox) Daytona sandbox; this client speaks HTTP/SSE to the sandbox endpoint via httpx.AsyncClient.

Spike-locked posture (ADR 0008 Phase 1b)

• Stateless /v1/chat/completions only. The full conversation history is sent in messages[] on every turn — Hermes' on-disk session DB is unused.
• Authorization: Bearer <API_SERVER_KEY> on every call. The bearer is the per-sandbox caller-side key minted at provision time; it is NOT an LLM key.
• Single OpenRouter credential-pool entry per sandbox (no rotation). Hermes resolves the OpenRouter key from process env at agent construction time.
• Model strings use the hermes/<openrouter-model-id> shape; the backend strips the hermes/ prefix before forwarding to Hermes.

Conversation metadata: speaker + participants

When auto_record=True (the default when window is supplied), the agent constructs a CopassTurnRecorder that auto-populates the envelope's typed metadata on every turn:

• speaker — set from the author constructor arg on assistant turns; falls back to "User" / "Assistant" from the role on user turns.
• participants — defaults to ["User", author or "Assistant"]. The roster rides on every turn so downstream retrieval can resolve second-person pronouns.

agent = CopassHermesAgent(
    identity="support",
    system_prompt="You are helpful.",
    sandbox_url=os.environ["HERMES_SANDBOX_URL"],
    api_server_key=os.environ["HERMES_API_KEY"],
    window=window,
    author="agent:support-bot",   # → speaker on every assistant turn
    # participants auto-defaults to ["User", "agent:support-bot"]
)

If you need a richer roster (multi-party threads) or a logged-in user identity, build a CopassTurnRecorder directly with participants=... and user_speaker="Alice", then pass auto_record=False to the agent and drive recording yourself. See copass-context-agents for the recorder surface and full envelope semantics.
