/context — collapse deferred MCP tools into a single summary line

Problem

When an MCP server exposes 100+ tools with tool search enabled, the /context command lists every deferred tool name individually. This produces a wall of ~130 lines that you have to scroll past every time you check context usage.

The actual context cost is tiny (341 tokens / 0.0% in my case), so the information density of listing each tool name is very low.

Current behavior

MCP tools · /mcp (loaded on-demand)

Loaded
└ mcp__houdini__ping: 91 tokens

Available
└ mcp__houdini__get_connection_status
└ mcp__houdini__get_scene_info
└ mcp__houdini__create_node
└ mcp__houdini__execute_houdini_code
... (130 more lines)

Requested behavior

Collapse deferred tools into a single summary line per MCP server:

MCP tools · /mcp (loaded on-demand)

Loaded
└ mcp__houdini__ping: 91 tokens

Available
└ mcp__houdini: 130 tools (on-demand)

An expand option (flag or interactive) would be a nice bonus for when you actually want the full list.

Environment

• Claude Code with Opus 4.6 (1M context)
• Houdini MCP server exposing ~140 tools
• Tool search already active and working correctly
