Adds bearer token authentication for the Bedrock Converse API, enabling users to authenticate with an API key instead of SigV4/IAM credentials. When a bearer token is available (via `options.bearerToken` or the `AWS_BEARER_TOKEN_BEDROCK` env var), the provider: 1. Sets dummy credentials to prevent SDK credential resolution errors 2. Injects middleware after SigV4 signing that replaces the Authorization header with `Bearer <token>` and removes SigV4-specific headers This uses the official `bedrock:CallWithBearerToken` IAM action, which is a documented AWS feature for API key auth on Bedrock endpoints. Use case: users who receive a Bedrock API key (bearer token) from the AWS console or their admin, without having IAM access keys or instance roles. Similar to how ANTHROPIC_API_KEY works for direct Anthropic API. Required IAM permission on the token's identity: bedrock:CallWithBearerToken Tested: Bearer token successfully authenticates against Bedrock Converse API (returns correct 403 for missing IAM permission, not auth format error). SigV4 path is unchanged when no bearer token is set.

Share your OSS coding agent sessions
If you use pi or other coding agents for open source work, please share your sessions.
Public OSS session data helps improve coding agents with real-world tasks, tool use, failures, and fixes instead of toy benchmarks.
For the full explanation, see this post on X.
To publish sessions, use badlogic/pi-share-hf. Read its README.md for setup instructions. All you need is a Hugging Face account, the Hugging Face CLI, and pi-share-hf.
You can also watch this video, where I show how I publish my pi-mono sessions.
I regularly publish my own pi-mono work sessions here:

See CONTRIBUTING.md for contribution guidelines and AGENTS.md for project-specific rules (for both humans and agents).
Development
npm install # Install all dependencies
npm run build # Build all packages
npm run check # Lint, format, and type check
./test.sh # Run tests (skips LLM-dependent tests without API keys)
./pi-test.sh # Run pi from sources (can be run from any directory)
Note:
npm run checkrequiresnpm run buildto be run first. The web-ui package usestscwhich needs compiled.d.tsfiles from dependencies.
