Phase 1-6: Foundation (Original Plan)

Phase 1: Tool Infrastructure ✅ Complete

Component	Status	Notes
BaseTool abstract class	✅	src/domains/tools/base.py
ToolResult dataclass	✅	Consistent success/error/truncated handling
ReadFileTool	✅	With line numbers, offset/limit support
GlobFilesTool	✅	Pattern matching, sorted by mtime

WebSearchTool	✅	SearXNG integration for web search
Path validation	✅	allowed_paths restriction

Status: Tools honor .gitignore patterns and default ignores (.venv/, __pycache__/, etc.)

Phase 2: Explore Agent ✅ Complete

Component	Status	Notes
BaseAgent abstract class	✅	src/domains/agents/base.py
Agent registry	✅	register_agent(), get_agent(), list_agents()
ExploreAgentImpl	✅	PydanticAI-based implementation
System prompts	✅	Mistral-optimized with tool examples
Tool registration	✅	@agent.tool decorator pattern
Sanitized Ollama provider	✅	Fixes content: null issue
Streaming support	✅	run_stream() method with SSE

Available tools: read_file, glob_files, grep_content, bash_readonly, edit_file, write_file, bash, web_search

Gap: Mistral Nemo sometimes hallucinates instead of using tool results.

Phase 2b: Plan Agent ✅ Complete

Component	Status	Notes
PlanAgentImpl	✅	READ-ONLY software architect agent
System prompts	✅	Architecture-focused with tool examples

Unit tests	✅	15 tests for registration, tools, API

Available tools: read_file, glob_files, grep_content, bash_readonly (read-only only)

Purpose: Design implementation strategies before coding - explores codebase and creates step-by-step plans.

Phase 3: CLI Foundation ✅ Complete

webber-cli --version	✅	Shows version from pyproject.toml
Console theming	✅	Centralized color palette

Database: SQLite (dev) or PostgreSQL (prod), async via SQLAlchemy 2.0

Phase 5: REST API ✅ Complete

Component	Status	Notes
POST /agents/run	✅	Execute agent with prompt
POST /agents/stream	✅	SSE streaming responses
GET /agents/	✅	List available agents
GET /agents/{name}	✅	Get agent info
Request/response schemas	✅	Pydantic models

Phase 6: Polish & Tests ✅ Complete

Component	Status	Notes
Tool unit tests	✅	109 tests total
API endpoint tests	✅	11 tests for agent routes
Health check tests	✅	2 tests
Security tests	✅	14 tests for path traversal, injection
Integration tests	✅	10 tests with real LLM (requires Ollama)
E2E tests	✅	12 tests against running API server

Known Issues

1. Model hallucination - Mistral Nemo sometimes makes up file contents instead of using actual tool results.

2. Temperature setting - Changed from 0.0 to 0.3 for Mistral Nemo compatibility, may affect determinism.

3. SQLAlchemy deprecation - datetime.utcnow() deprecation warning from SQLAlchemy.

Architecture Decisions Made

Decision	Choice	Rationale
Monorepo structure	webber-api/, webber-cli/	Separate packages, shared root
Sanitized Ollama provider	Custom wrapper	Fixes PydanticAI + Ollama content: null bug
Dev port 8095	Separate from prod 8086	Avoid conflicts with Docker deployment
Tool choice "required"	Force tool use	Mistral Nemo needs explicit instruction
Temperature 0.3	Mistral recommendation	0.0 caused issues with Nemo
SearXNG for search	Self-hosted	Privacy, no API keys needed
SSE for streaming	Server-Sent Events	Simple, well-supported
