Thank you for the detailed report and logs, @videni. This error indicates the AI agent completed its turn but did not call done(status="ok") after editing the workspace — a required step in the v0.2 agent workflow (AGENTS.md). The parse_response phase rejects the result because the final done tool was not invoked.

Likely causes to investigate:

1. Model behavior: The model (claude-opus-4-7) may not reliably follow instructions to call done() at the end of a turn. Try a different model (e.g., claude-sonnet-4-20250514 or gpt-4o) to see if the issue persists.
2. Provider/relay: You're using a custom Anthropic provider via cliproxyapi — the relay may be truncating or modifying the response, dropping the done tool call. Verify the relay passes the full response unchanged.
3. System prompt / temperature: If you've customized system prompts or temperature, the model might skip the done step. Try default settings.

To help narrow it down, please provide:

• The full diagnostics bundle (~/Downloads/open-codesign-diagnostics-2026-05-14T03-41-00.zip) — it contains the session JSONL and exact configuration.
• Does this happen with every prompt using this model/provider, or only some?
• Have you tested with other models (e.g., claude-sonnet-4, gpt-4o, gemini-2.5-pro) on the same provider?
• The base URL of your custom proxy (omit keys) — to check if it's a known relay compatibility issue.

Relevant code:

• The error originates in packages/core/src/generate.ts — the parse_response step checks for the done tool call after the agent session ends.
• The done tool is defined in packages/core/src/tools/done.ts (declared via pi-coding-agent).

Let's figure this out! ✨

Thank you for the detailed logs, @videni. The key clue is in your logs: tools: 0 — the agent produced deltas (text) but no tool calls at all. In v0.2, every agent turn is expected to end with a done tool call (defined in AGENTS.md). When the model returns only text without invoking any tools, the parse_response step sees no done and raises GENERATION_INCOMPLETE.

Root-cause directions:

1. Relay stripping tool calls: You're using a custom Anthropic provider via cliproxyapi. Some proxies or relays strip tool_use content blocks from the response or don't forward them from the upstream model. Verify that your relay passes raw Anthropic tool_use blocks through unchanged. This is the most likely cause.

2. Model identity: claude-opus-4-7 is not a standard Anthropic model ID. If this is an alias or a relayed model, it may not support function calling as expected. Try using a known Anthropic model ID (e.g., claude-sonnet-4-20250514) directly if possible.

3. No tools in response: The agent.turn_end event shows deltas: 4, tools: 0 — the model replied with only text content. This confirms the model never decided to call done (or any tool).

Relevant code path:

• packages/core/src/generate.ts — parse_response checks for the final done tool call and rejects if missing.
• packages/core/src/tools/done.ts — defines the done tool schema registered with pi-coding-agent.

To help narrow this down, please provide:

• The diagnostics bundle from ~/Downloads/open-codesign-diagnostics-2026-05-14T03-41-00.zip — it contains the full session JSONL showing the raw model response.
• Does this happen with every prompt using this provider/model, or only sometimes? Have you tested with a non-custom Anthropic provider (e.g., direct api.anthropic.com key)?
• What exact upstream model does your relay map claude-opus-4-7 to? Does that model support function calling?
• The base URL of your cliproxyapi (redact secrets) — to check for known relay compatibility issues.

Let's debug this together! 🙌
