chore: release api v1.0.0

- Event-based streaming for task agent
- Retry logic when LLM responds without calling tools
- Hardened prompts to enforce tool use
- Working directory context in all agent prompts
- Project paused: local LLMs not capable enough for agentic use

-- `cli/v0.1.0` → Triggers CLI build (future)
+- `api/vX.Y.Z` → Triggers API Docker build
+- `cli/vX.Y.Z` → Triggers CLI build (future)
+
+### MANDATORY Release Procedure
+
+**NEVER push a tag before updating version files.** Follow this exact order:
 
 ```bash
-# API release
-cd webber-api
-# Update version in pyproject.toml
-git add -A && git commit -m "chore: release api v0.3.0"
-git tag api/v0.3.0
+# For API releases:
+# 1. Update version in webber-api/pyproject.toml
+# 2. Update webber-api/CHANGELOG.md with release notes
+# 3. Commit the version bump
+git add -A && git commit -m "chore: release api vX.Y.Z"
+# 4. Create the tag (AFTER the commit)
+git tag api/vX.Y.Z
+# 5. Push everything together
+git push origin main --tags
+
+# For CLI releases:
+# 1. Update version in webber-cli/pyproject.toml
+# 2. Update webber-cli/CHANGELOG.md with release notes
+# 3. Commit the version bump
+git add -A && git commit -m "chore: release cli vX.Y.Z"
+# 4. Create the tag (AFTER the commit)
+git tag cli/vX.Y.Z
+# 5. Push everything together
 git push origin main --tags
 ```
 
+**Why this matters:** Pushing a tag before the version commit requires deleting and recreating the tag, which can trigger CI/CD pipelines prematurely and cause deployment issues.

 ## Known Limitations
 
 1. **Model hallucination** - Mistral Nemo sometimes makes up file contents instead of using tool results
-2. **No conversation memory** - CLI chat mode doesn't persist between sessions
-3. **No streaming** - Responses appear all at once

+# Changelog - Webber API
+
+All notable changes to the Webber API will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [Unreleased]
+
+## [1.0.0] - 2026-01-15
+
+### Added
+- Event-based streaming for task agent (`StreamEvent` objects instead of raw text)
+  - New `tools_streaming.py` with all tools emitting structured events
+  - Event types: `tool_start`, `tool_done`, `thinking`, `response`, `error`, `done`
+- Retry logic when LLM responds without calling tools (max 2 retries)
+  - Tracks `tools_called` counter on TaskContext
+  - Stronger retry prompt forces tool use
+- Working directory context injected into all agent prompts
+
+### Changed
+- Hardened system prompts to enforce tool use before responding
+  - Added "CRITICAL RULE" section requiring tool calls first
+  - Made "MANDATORY WORKFLOW" more emphatic
+- Updated explore and plan agents with `_build_prompt_with_context()` method
+
+### Fixed
+- Agent path hallucination - now explicitly communicates working directory to LLM
+
+### Note
+- Project paused: Local LLMs (Mistral Nemo 12B on available hardware) are not capable enough for reliable agentic tool use. Models frequently hallucinate responses instead of calling tools, even with prompt hardening and retry logic. Would require larger models (70B+) or cloud API integration to continue.
+
+## [0.4.2] - 2026-01-11
+
+### Added
+- Retry logic for transient failures with exponential backoff
+  - `src/shared/retry.py` - `@with_retry` decorator and `retry_async()` function
+  - Retries on: timeout, connection errors, HTTP 429/5xx
+  - Configurable: `RETRY_MAX_ATTEMPTS`, `RETRY_BASE_DELAY`, `RETRY_MAX_DELAY`
+- Web search tool now automatically retries on network failures
+- 29 retry tests (205 total tests passing)
+
+## [0.4.1] - 2026-01-11
+
+### Fixed
+- Replace `litellm` with `tiktoken` for token counting (dependency conflict with pydantic-ai)
+- Update documentation (README.md, architecture.md) with conversation layer info
+
+## [0.4.0] - 2026-01-11
+
+### Added
+- Conversation persistence layer with SQLAlchemy async
+  - Database models: `Conversation`, `Message` with UUID primary keys
+  - SQLite (dev) and PostgreSQL (prod) support via async engines
+  - Lazy database initialization pattern
+- Context management infrastructure
+  - Token counting utilities using `tiktoken`
+  - Context summarization at 80% token threshold
+  - XML-tagged context prompt building for agent injection
+- REST API for multi-turn conversations
+  - `POST /conversations/` - Create new conversation
+  - `GET /conversations/` - List conversations
+  - `GET /conversations/{id}` - Get conversation with history
+  - `POST /conversations/{id}/messages` - Add message (triggers agent)
+  - `DELETE /conversations/{id}` - Delete conversation
+- New dependencies: `sqlalchemy[asyncio]~=2.0.36`, `aiosqlite~=0.21.0`, `tiktoken>=0.12.0`
+- Config settings: `database_url`, `summarization_threshold`, `keep_recent_messages`
+- 19 conversation tests, 6 token counting tests (176 total tests passing)
+
+### Changed
+- Updated COVERAGE.md to ~80% complete
+- Quieter pytest output (`-q --tb=short` instead of `-v`)
+
+## [0.3.4] - 2026-01-11
+
+### Added
+- Task Agent - Full orchestrator for autonomous multi-step task execution
+  - Has ALL tools: read, write, edit, bash (full), web_search
+  - New `spawn_agent` tool to launch sub-agents (Explore, Plan) for focused work
+  - Recursion prevention: cannot spawn nested Task agents
+  - 22 unit tests for registration, tools, spawn_agent, and API
+- Complete agent hierarchy: Explore (read-only) → Plan (read-only) → Task (orchestrator)
+
+## [0.3.3] - 2026-01-11
+
+### Added
+- Plan Agent - READ-ONLY software architect that designs implementation strategies
+  - Uses only read-only tools: `read_file`, `glob_files`, `grep_content`, `bash_readonly`
+  - Creates step-by-step implementation plans with critical files list
+  - 15 unit tests for registration, tools, and API
+- Web search summarizer added to roadmap (future feature)
+
+### Changed
+- Updated COVERAGE.md to ~70% complete
+
+## [0.3.2] - 2026-01-11
+
+### Added
+- Mandatory release procedure documentation in AGENTS.md
+
+## [0.3.1] - 2026-01-11

-| Separate CLI package | `cli/` at root | Can be extracted as standalone client |
+| Monorepo structure | `webber-api/`, `webber-cli/` | Separate packages, shared root |
 | Sanitized Ollama provider | Custom wrapper | Fixes PydanticAI + Ollama `content: null` bug |

+## Database Layer
+
+SQLAlchemy 2.0 async with lazy initialization pattern.
+
+### Supported Databases
+- **Development**: SQLite via `aiosqlite`
+- **Production**: PostgreSQL via `asyncpg`
+
+### Pattern
+```python
+from src.db import get_session
+from sqlalchemy.ext.asyncio import AsyncSession
+
+async def my_endpoint(session: AsyncSession = Depends(get_session)):
+    # Session auto-commits on success, rollbacks on exception
+    result = await session.execute(query)
+```
+
+Tables are created lazily on first `get_session()` call.
+
+---
+
+## Conversation API
+
+Multi-turn conversation memory with automatic context summarization.
+
+### Endpoints
+| Endpoint | Method | Description |
+|----------|--------|-------------|
+| `/conversations/` | POST | Create new conversation |
+| `/conversations/` | GET | List user's conversations |
+| `/conversations/{id}` | GET | Get conversation with history |
+| `/conversations/{id}/messages` | POST | Add message, triggers agent |
+| `/conversations/{id}` | DELETE | Delete conversation |
+
+### Models
+- **Conversation**: User session with agent type, working directory
+- **Message**: Individual messages with role, content, token count
+
+### Context Summarization
+When total tokens exceed 80% of `MAX_CONTEXT_TOKENS`:
+1. Keep last 6 messages intact
+2. Summarize older messages into a single summary message
+3. Mark old messages as summarized (soft delete)
+
+---
+
 ## Authentication Flow
 
 1. Client sends `X-API-Key` header

+"""
+
+PLAN_SYSTEM_PROMPT = """You are a software architect and planning specialist.
+
+Your role is to explore codebases and design implementation plans.
+
+CRITICAL: You are READ-ONLY. You CANNOT modify any files.
+
+AVAILABLE TOOLS:
+- glob_files: Find files by pattern
+- read_file: Read file contents
+- grep_content: Search code with regex
+- bash_readonly: Run read-only commands (ls, git status, git log, etc.)
+
+WORKFLOW:
+1. Understand the requirements
+2. Explore the codebase to find relevant patterns and conventions
+3. Design an implementation approach
+4. Create a step-by-step plan with specific files and changes
+
+TOOL CALL EXAMPLES (follow exactly):
+
+To find Python files:
+  Call glob_files with pattern="**/*.py"
+
+To find a specific file:
+  Call glob_files with pattern="**/config.py"
+
+To read a file:
+  Call read_file with file_path="/absolute/path/to/file.py"
+
+To search for code patterns:
+  Call grep_content with pattern="class.*Controller"
+
+To check git history:
+  Call bash_readonly with command="git log --oneline -10"
+
+OUTPUT FORMAT:
+End your response with:
+
+### Implementation Steps
+1. [First step with specific file and changes]
+2. [Second step...]
+3. [Continue...]
+
+### Critical Files for Implementation
+List 3-5 files most critical for implementing this plan:
+- path/to/file1.py - [Brief reason: e.g., "Core logic to modify"]
+- path/to/file2.py - [Brief reason: e.g., "Pattern to follow"]
+
+RULES:
+- ALWAYS use tools first, then analyze results
+- Follow existing patterns in the codebase
+- Consider trade-offs and alternatives
+- Identify dependencies and sequencing
+- Never guess - verify with tools
+- Provide specific file paths and code locations

+- If you respond without calling a tool first, YOUR ANSWER IS WRONG
+
+You can explore and analyze code but CANNOT modify files or execute write operations.

+  Call spawn_agent with agent_type="explore" and prompt="find all config files"
+
+To spawn a Plan agent for design:
+  Call spawn_agent with agent_type="plan" and prompt="design user auth feature"
+
+To edit a file:
+  Call edit_file with file_path="/path/to/file.py" and old_string="old" and new_string="new"
+
+To run tests:
+  Call bash with command="pytest tests/ -v"
+
+SPAWN_AGENT USAGE:
+- Use spawn_agent to offload focused tasks to specialized agents
+- Explore agent: Fast codebase searches and analysis
+- Plan agent: Design implementation strategies
+- Keep each agent's context focused and efficient
+
+GIT DISCIPLINE:
+- Create feature branches for changes
+- Use conventional commit format (feat:, fix:, docs:, etc.)
+- Never commit directly to main
+- Run tests before committing
+
+RULES:
+- ALWAYS call a tool FIRST - no exceptions
+- Never guess or fabricate - only report what tools return
+- Prefer edit_file over write_file for existing files
+- Use spawn_agent to keep context focused
+- Validate changes by running tests when applicable
+
+OUTPUT FORMAT:
+End your response with a summary:
+
+### Task Summary
+- **Accomplished:** What was done
+- **Files modified:** List of changed files
+- **Commands run:** Key commands executed
+- **Issues:** Any problems encountered
