Send tasks to a cheaper/faster model in a fresh context with auto model selection, tool access, and MCP support.

Features

• Auto model selection — picks the best close model match for the task category, never exceeding the current model's tier
• Provider-aware matching — searches configured providers for equivalents to the Copilot reference model list while excluding azure- providers. Equal-scoring matches prefer the reference's github-copilot provider, and auto-selection falls back across providers if a chosen model has no usable credentials (e.g. a stale openai-codex OAuth entry), so one unauthenticated provider cannot keep breaking delegation.
• Settings pane — searchable provider checkboxes, configurable provider/model exclusions, plus a model-list refresh action
• 6 task categories — quick, summarize, code, analyze, reason, judge
• Tool access — delegate has read, grep, find, ls, bash, MCP tools by default
• MCP support — any servers in .pi/mcp.json are available
• Multimodal — images/PDFs passed as native attachments with automatic tier bumping
• Judge mode — cross-family second opinion for reviewing agent responses
• Skills — all .pi/skills/ auto-discovered (web-search, etc.)
• Fresh context — no conversation history, saves tokens

Install

Open Settings → Add-Ons and install delegate from the catalog.

Then restart PiClaw. The extension auto-activates itself.

Optional: config-based activation

You can also add delegate to the default active tools in .piclaw/config.json:

{
  "tools": {
    "additionalDefaultTools": ["delegate"]
  }
}

Stress test results

Tested on 12-core / 7.5GB container (github-copilot provider):

Safe for up to 20 concurrent calls. Bottleneck is API rate limits, not local resources.

Running the stress test

# Phase 1: basic concurrency (1, 2, 3, 5, 8, 10)
bun tests/delegate-stress-test.ts

# Phase 2: higher load + memory monitoring (10, 15, 20, 25, 30)
bun tests/delegate-stress-test-2.ts

This is redundant if using the extension (it self-activates), but useful if you want explicit config control.
