From c33e01ee621aece07d2d1f614a261c02628fb4cf Mon Sep 17 00:00:00 2001 From: MiguelPF Date: Wed, 18 Mar 2026 10:11:01 +0100 Subject: [PATCH 01/68] fix(cron): scope cron job store to workspace instead of global directory Replace `get_cron_dir()` with `config.workspace_path / "cron"` so each workspace keeps its own `jobs.json`. This lets users run multiple nanobot instances with independent cron schedules without cross-talk.

Restructure to check for local paths (plain path or file:// URI) before URL validation, so files like /home/.../.nanobot/workspace/generated_image.svg can be read and sent correctly. - Add .svg to _IMAGE_EXTS so SVG files are uploaded as file_type=1 (image) instead of file_type=4 (file). - Add tests for local path, file:// URI, and missing file cases.

An optional global concurrency cap is available via the NANOBOT_MAX_CONCURRENT_REQUESTS env var (default 3, <=0 for unlimited). Also re-binds tool context before each tool execution round to prevent concurrent sessions from clobbering each other's routing info. Tested in production and manually reviewed.

Root cause: The system prompt stated "Reply directly with text for conversations. Only use the 'message' tool to send to a specific chat channel", which led the LLM to believe text replies were sufficient for all responses, including file delivery. Fix: Add an explicit IMPORTANT instruction in the system prompt telling the LLM it MUST use the 'message' tool with the 'media' parameter to send files, and that read_file only reads content for its own analysis.

Each delta triggers a separate API call (~700ms each), causing visible delay after LLM finishes. Solution: In _dispatch_outbound, drain all queued deltas for the same (channel, chat_id) before sending, combining them into a single API call. Non-matching messages are preserved in a pending buffer for subsequent processing.

Includes 17 new unit tests covering streaming lifecycle, config, card building, and edge cases. Made-with: Cursor * feat(feishu): close CardKit streaming_mode on stream end Call cardkit card.settings after final content update so chat preview leaves default [生成中...] summary (Feishu streaming docs).
