[Plugin] dsh-tool-lazy-dispatcher: Dynamic Lazy Tool Folding & Progressive Disclosure for DeepSeek Harness

[tigermkiiiddd]

Hi everyone! 👋

I've been heavily using DeepSeek Harness with multiple MCP servers (Chrome DevTools, database tools, custom media pipelines, etc.). As the tool count quickly climbed past 30–50+, I ran into two major pain points:

1. Context overhead: Full JSON schemas for dozens of tools are injected on every single turn, eating away thousands of prompt tokens before the conversation even starts.
2. Model distraction: Having too many specialized tool schemas in the top-level wire prompt increases the risk of the model hallucinating parameters or choosing the wrong tool.

To solve this, I built and open-sourced dsh-tool-lazy-dispatcher — a dynamic lazy-folding and progressive-disclosure dispatcher for DeepSeek Harness.

💡 How It Works (Progressive Disclosure)

• 📌 Zero-Latency Core Tools: Essential tools (
  ead, write, edit, pwsh, �ash, web_search, subagent, etc.) remain permanently pinned in the wire schema.
• 📦 Smart Lazy Folding: Infrequent and heavy domain tools are folded into a compact catalog in the system prompt with descriptions truncated to 120 chars, cutting 70%+ of tool-schema token overhead.
• 🔍 On-Demand Discovery (list_tools): The model can search tools by keyword (�ction: "search", query: "...") or list them by category on demand.
• 📋 Schema Inspection (get_tool_schema): Fetches full parameters only when the model actually decides to use a folded tool.
• ⚡ Universal Execution Proxy (call_tool): Transparently delegates calls to folded tools with proper error isolation.
• 🖼️ Full Media & Screenshot Preservation: Passes structured ContentBlock directly, ensuring images and screenshots from MCP tools (e.g., Chrome take_screenshot) remain intact and are never lost or downgraded to plain text.
