Progressive-disclosure MCP gateway that searches large remote catalogs through `mcp_search`, then invokes exact schemas through `mcp_call` with lazy connections and bounded caches.

On-demand tool groups for DeepSeek Harness, with optional role-scoped tool surfaces. Role masks are off by default; Settings can enable or disable review/build/research, and add custom roles with a group allow-list. The role key comes from the host's session label, subagent marker or preset, so an orchestrator's child agents each see only their own allow-list. Also auto-groups tool families by name prefix, lets the agent classify ungrouped tools once, restores a hidden tool when it is actually called, and reports per-session visibility health.

Skill manager for the DeepSeek Harness sidebar: lists global and project-level skills with call counts, last-used dates and estimated context tokens, and archives or restores a skill by moving its directory into a reversible skills-archived next to the skills root.

Converts Office and PDF files in the DSH workspace to Markdown locally — no network, no API quota — before the model reads them. Writes each .md next to its source so only a file path enters the context, and returns byte size, line count, token estimate and a heading outline, for a single file or a whole directory.

On-demand MCP tool loading. Only the mcp__* tools listed in the coreTools whitelist (max 5) stay in a session's tool set; every other MCP tool definition is actually removed from the request through the session-scoped tools.restrict() API and comes back only after the model calls lazy_load_tool. A tools/pre-execute gate turns calls to unloaded tools into a load-it-first error, and activation resets when the session ends.
