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
GrepContentTool	✅	Regex search with context lines
BashReadOnlyTool	✅	Allowlist-based command filtering
EditFileTool	✅	Find-and-replace with unique match validation
WriteFileTool	✅	Create/overwrite files with size limits
BashTool (full)	✅	Write-enabled shell with safety controls
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
Tool registration	✅	Only read-only tools (4 tools)
Streaming support	✅	run_stream() method with SSE
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

Component	Status	Notes
Typer + Rich setup	✅	Standalone webber-cli/ package
webber-cli --version	✅	Shows version from pyproject.toml
Console theming	✅	Centralized color palette
Markdown rendering	✅	Rich markdown output
Streaming display	✅	Real-time token output with --stream flag

Phase 4: Agentic Loop ⚠️ Partial

Component	Status	Notes
webber-cli chat command	✅	Interactive mode with streaming
webber-cli explore command	✅	One-shot query with streaming
SessionState dataclass	✅	Basic context tracking
AgenticLoop class	⚠️	Basic implementation, not fully utilized
Conversation history	❌	Not persisted between turns in CLI
Context management	❌	No token counting or summarization

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. No conversation memory - CLI chat mode doesn't persist context between sessions.

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

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

Quick Reference: What Works Now

# Start dev server
cd webber-api && ./wakeup.sh

# CLI commands (from webber-cli/)
.venv/bin/webber-cli status                    # Check API connection
.venv/bin/webber-cli explore "find tests"      # One-shot exploration
.venv/bin/webber-cli explore "query" --no-stream  # Batch mode
.venv/bin/webber-cli chat                      # Interactive mode

# API endpoints
curl http://localhost:8095/health
curl http://localhost:8095/agents/
curl -X POST http://localhost:8095/agents/run \
  -H "Content-Type: application/json" \
  -d '{"agent_type":"explore","prompt":"list python files","working_dir":"."}'

# Plan agent (read-only, creates implementation plans)
curl -X POST http://localhost:8095/agents/run \
  -H "Content-Type: application/json" \
  -d '{"agent_type":"plan","prompt":"plan how to add user auth","working_dir":"."}'

# Streaming endpoint
