…ements Implement a comprehensive set of agent tools inspired by leading AI coding agents (Cursor, Windsurf, Aider, Cline, Devin). Includes web interaction, codebase intelligence, persistence, document processing, and MCP protocol enhancements. New tools: - web-fetch, web-search: web interaction with HTML parsing and multi-engine search - codebase-map: full codebase structure analysis (classes, interfaces, functions, dependencies) - checkpoint: git stash-based state snapshots with restore/diff - memory: persistent cross-session key-value memory store - semantic-search: vector-based code search with optional transformer embeddings - diagram: Mermaid diagram generation (class, sequence, flowchart, ER, dependency) - pdf: PDF text extraction with page range support - image: multi-provider image analysis (Anthropic, OpenAI, Gemini) - database: SQLite read/query with schema introspection - diff: unified diff viewing tool - review: automated code review with multi-dimension scoring - permissions: permission management utilities MCP improvements: - SSE transport with auto-reconnect and exponential backoff - readResource() and getPrompt() client methods - jsonSchemaToZod converter with full JSON Schema support (enum, oneOf, anyOf, allOf, const, nullable) - Server lifecycle manager with health checks and singleton pattern - Extended type exports and barrel module Also includes: enhanced REPL (coco-mode, diff renderer, syntax highlighting, bash patterns, recommended permissions), config schema extensions, and ambient type declarations for optional dependencies.
