acp_dart 0.3.0

A Dart implementation of the Agent-Client Protocol (ACP) for building AI-powered applications.

0.3.0

• Protocol Parity: Rebuilt every data model to match the official ACP schema.json, including sessions, permissions, plans, content payloads, terminal updates, MCP server descriptors, and _meta envelopes; regenerated schema.g.dart to keep serialization in lock-step.
• Filesystem Coverage: Restored delete/move/mkdir/list operations, ensured each request carries the appropriate sessionId, path fields, and limits, and aligned WaitForTerminalExit and related responses with nullable exit metadata.
• Typed RPC Unions: Introduced sealed Agent/Client request, response, and notification unions with exhaustive handling and constant tables; added comprehensive round-trip tests plus HTTP and SSE example flows that exercise the new types end-to-end.
• Converters & Utilities: Harmonized converters for session updates, MCP servers, permission requests, and tool-call content, removing non-spec variants while preserving forward-compatible Unknown* fallbacks.
• Stability Fixes: Corrected numerous spec mismatches (capability flags, optionality, naming, prompt payloads) and tightened serialization behaviors to prevent regressions.
• Docs & Testing: Updated research notes, tracked schema alignment in schema_alignment_checklist.md, refreshed examples, and broadened test coverage to guard the new behavior.

0.2.0

• Fix: Resolved critical bug in NDJSON stream handling (lib/src/stream.dart) that caused communication failures due to incorrect UTF-8 and line splitting logic.
• Fix: Corrected InitializeRequest and InitializeResponse to properly handle numeric protocolVersion and use clientCapabilities key, resolving initialization errors with ACP backends.
• Feature: Added unstable Agent.setSessionModel method for feature parity with the latest ACP TypeScript SDK.

0.1.0

• Initial release of the acp_dart package.
• Implements the core functionality of the Agent-Client Protocol (ACP).
