Fixes issue where unpaired Unicode surrogates in tool results cause JSON serialization errors in API providers, particularly Anthropic. - Add sanitizeSurrogates() utility function to remove unpaired surrogates - Apply sanitization in all provider convertMessages() functions: - User message text content (string and text blocks) - Assistant message text and thinking blocks - Tool result output - System prompts - Valid emoji (properly paired surrogates) are preserved - Add comprehensive test suite covering all 8 providers Previously only Google and Groq handled unpaired surrogates correctly. Now all providers (Anthropic, OpenAI Completions/Responses, Google, xAI, Groq, Cerebras, zAI) sanitize text before API submission.

Development
This is a monorepo using npm workspaces for package management and a dual TypeScript configuration for development and building.
Common Commands
# Install all dependencies
npm install
# Build all packages (required for publishing to NPM)
npm run build
# Clean out dist/ folders in all packages
npm run clean
# Run linting, formatting, and tsc typechecking (no build needed)
npm run check
# Run directly with tsx during development (no build needed)
cd packages/pods && npx tsx src/cli.ts
cd packages/agent && npx tsx src/cli.ts
Package Dependencies
The packages have the following dependency structure:
pi-tui -> pi-agent -> pi
When new packages are added, the must be inserted in the correct order in the build script in package.json.
TypeScript Configuration
The monorepo uses a dual TypeScript configuration approach:
- Root
tsconfig.json: Contains path mappings for all packages, used for type checking and development withtsx - Package
tsconfig.build.json: Clean build configuration withrootDirandoutDir, used for production builds
This setup allows:
- Type checking without building (
npm run checkworks immediately) - Running source files directly with
tsxduring development - Clean, organized build outputs for publishing
Versioning
All packages use lockstep versioning - they share the same version number:
# Bump patch version (0.5.0 -> 0.5.1)
npm run version:patch
# Bump minor version (0.5.0 -> 0.6.0)
npm run version:minor
# Bump major version (0.5.0 -> 1.0.0)
npm run version:major
These commands automatically:
- Update all package versions
- Sync inter-package dependency versions
- Update package-lock.json
Publishing
# Dry run to see what would be published
npm run publish:dry
# Publish all packages to npm
npm run publish
