gsxdsm ad416b5581 fix(pi-claude-cli): teach Claude to call deferred MCP tools by their prefixed names

Claude Code 2.x defers MCP tool schemas behind ToolSearch — tools are listed
but calling them by short name (e.g. fn_review_spec) returns "tool not found"
until ToolSearch loads the schema. Triage system prompts that say "call
fn_review_spec()" leave the model guessing whether to use the bare name or
the mcp__custom-tools__ form.

Append a system-prompt section listing every custom tool with its short and
MCP-prefixed names plus the ToolSearch + call protocol. Drives off the
Context.tools we now already thread through, so plain chats with no custom
tools get no addendum.

pi-claude-cli

A pi extension that routes LLM calls through the Claude Code CLI as a subprocess. Use your Claude Pro/Max subscription as the LLM backend — no API key, no separate billing.

How it works

The extension registers as a custom pi provider exposing all Claude models. Each request spawns a claude -p subprocess using the stream-json wire protocol, with --resume on follow-up turns to reuse the CLI's session state instead of replaying full history. Claude proposes tool calls, pi executes them natively. Custom pi tools are exposed to Claude via a schema-only MCP server.

Requirements

Claude Code CLI installed and authenticated (claude on PATH)
A Claude Pro or Max subscription
pi or GSD

Installation

Add to ~/.gsd/agent/settings.json:

{
  "packages": ["npm:pi-claude-cli"]
}

Then select a Claude model via /model in the interactive UI. All Claude models appear under the pi-claude-cli provider.

Features

Streams text, thinking, and tool call tokens in real-time
Maps tool names and arguments bidirectionally between Claude and pi
Exposes custom pi tools to Claude via MCP (schema-only, no execution)
Break-early pattern prevents Claude CLI from auto-executing tools
Session resume via --resume eliminates history replay on follow-up turns
Configurable thinking effort with elevated budgets for Opus models
Cross-platform subprocess management (Windows, macOS, Linux)
Inactivity timeout and process registry for cleanup
