pi-google-url-context
May 12, 2026 · View on GitHub
Google native URL context extension for the pi coding agent.
This package is the standalone extraction of senpi's former builtin google-url-context extension.
Behavior
The extension does not register a new tool. It intercepts Google provider requests before they are sent and ensures a native urlContext tool is present for google-generative-ai / google-vertex payloads when URL context is enabled via default-on env toggle.
| Case | Result |
|---|---|
API is google-generative-ai or google-vertex, PI_GOOGLE_URL_CONTEXT is unset/empty/truthy/unknown, and no Tool object has a urlContext key | injects a new Tool entry { urlContext: {} } |
Existing Tool object already has urlContext key (any value) | preserves caller payload without duplication or overwrite |
Existing Tool object has only functionDeclarations | keeps that object and adds separate { urlContext: {} } entry |
PI_GOOGLE_URL_CONTEXT is falsy (0/false/no/off) | no-op |
| API is non-Google | no-op |
Truthy values for PI_GOOGLE_URL_CONTEXT are: 1, true, yes, on (case-insensitive, surrounding whitespace allowed). Unknown values follow documented default-on behavior.
It also appends a system-prompt section for Google sessions indicating native url_context availability when enabled.
Installation
The package targets the pi coding agent. Pi loads extensions from ~/.pi/agent/extensions/, project .pi/extensions/, or via the --extension / -e CLI flag.
# From npm (once published)
pi install npm:pi-google-url-context
# From git
pi install git:github.com/code-yeongyu/pi-google-url-context
# Manual placement
git clone https://github.com/code-yeongyu/pi-google-url-context ~/.pi/agent/extensions/pi-google-url-context
cd ~/.pi/agent/extensions/pi-google-url-context && npm install
# Dev / one-shot test
pi -e /path/to/pi-google-url-context/src/index.ts
After installation, restart pi or run /reload inside an interactive session.
Development
npm install
npm test
npm run typecheck
npm run check
pi -e ./src/index.ts
The test suite uses vitest. TypeScript is strict, Node-only, and uses ESM imports with .js suffixes.
Origin
Ported from packages/coding-agent/src/core/extensions/builtin/google-url-context/index.ts in the senpi-mono fork of pi-mono.
