+# The Ouroboros

-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+AI-powered trading agent for global stock markets with self-evolution capabilities.

-## Git Workflow Policy
+## Quick Start

-**CRITICAL: All code changes MUST follow this workflow. Direct pushes to `main` are ABSOLUTELY PROHIBITED.**
-
-1. **Create Gitea Issue First** — All features, bug fixes, and policy changes require a Gitea issue before any code is written
-2. **Create Feature Branch** — Branch from `main` using format `feature/issue-{N}-{short-description}`
-3. **Implement Changes** — Write code, tests, and documentation on the feature branch
-4. **Create Pull Request** — Submit PR to `main` branch referencing the issue number
-5. **Review & Merge** — After approval, merge via PR (squash or merge commit)
-
-**Never commit directly to `main`.** This policy applies to all changes, no exceptions.
-
-## Agent Workflow
-
-**Modern AI development leverages specialized agents for concurrent, efficient task execution.**
-
-### Parallel Execution Strategy
-
-Use **git worktree** or **subagents** (via the Task tool) to handle multiple requirements simultaneously:
-
- Each task runs in independent context
- Parallel branches for concurrent features
- Isolated test environments prevent interference
- Faster iteration with distributed workload
-
-### Specialized Agent Roles
-
-Deploy task-specific agents as needed instead of handling everything in the main conversation:
-
- **Conversational Agent** (main) — Interface with user, coordinate other agents
- **Ticket Management Agent** — Create/update Gitea issues, track task status
- **Design Agent** — Architectural planning, RFC documents, API design
- **Code Writing Agent** — Implementation following specs
- **Testing Agent** — Write tests, verify coverage, run test suites
- **Documentation Agent** — Update docs, docstrings, CLAUDE.md, README
- **Review Agent** — Code review, lint checks, security audits
- **Custom Agents** — Created dynamically for specialized tasks (performance analysis, migration scripts, etc.)
-
-### When to Use Agents
-
-**Prefer spawning specialized agents for:**
-
-1. Complex multi-file changes requiring exploration
-2. Tasks with clear, isolated scope (e.g., "write tests for module X")
-3. Parallel work streams (feature A + bugfix B simultaneously)
-4. Long-running analysis (codebase search, dependency audit)
-5. Tasks requiring different contexts (multiple git worktrees)
-
-**Use the main conversation for:**
-
-1. User interaction and clarification
-2. Quick single-file edits
-3. Coordinating agent work
-4. High-level decision making
-
-### Implementation
-
-```python
-# Example: Spawn parallel test and documentation agents
-task_tool(
-    subagent_type="general-purpose",
-    prompt="Write comprehensive tests for src/markets/schedule.py",
-    description="Write schedule tests"
-)
-
-task_tool(
-    subagent_type="general-purpose",
-    prompt="Update README.md with global market feature documentation",
-    description="Update README"
-)
-```
-
-Use `run_in_background=True` for independent tasks that don't block subsequent work.
-
-## Common Command Failures
-
-**Critical: Learn from failures. Never repeat the same failed command without modification.**
-
-### tea CLI (Gitea Command Line Tool)
-
-#### ❌ TTY Error - Interactive Confirmation Fails
-```bash
-~/bin/tea issues create --repo X --title "Y" --description "Z"
-# Error: huh: could not open a new TTY: open /dev/tty: no such device or address
-```
-**💡 Reason:** tea tries to open `/dev/tty` for interactive confirmation prompts, which is unavailable in non-interactive environments.
-
-**✅ Solution:** Use `YES=""` environment variable to bypass confirmation
-```bash
-YES="" ~/bin/tea issues create --repo jihoson/The-Ouroboros --title "Title" --description "Body"
-YES="" ~/bin/tea issues edit <number> --repo jihoson/The-Ouroboros --description "Updated body"
-YES="" ~/bin/tea pulls create --repo jihoson/The-Ouroboros --head feature-branch --base main --title "Title" --description "Body"
-```
-
-**📝 Notes:**
- Always set default login: `~/bin/tea login default local`
- Use `--repo jihoson/The-Ouroboros` when outside repo directory
- tea is preferred over direct Gitea API calls for consistency
-
-#### ❌ Wrong Parameter Name
-```bash
-tea issues create --body "text"
-# Error: flag provided but not defined: -body
-```
-**💡 Reason:** Parameter is `--description`, not `--body`.
-
-**✅ Solution:** Use correct parameter name
-```bash
-YES="" ~/bin/tea issues create --description "text"
-```
-
-### Gitea API (Direct HTTP Calls)
-
-#### ❌ Wrong Hostname
-```bash
-curl http://gitea.local:3000/api/v1/...
-# Error: Could not resolve host: gitea.local
-```
-**💡 Reason:** Gitea instance runs on `localhost:3000`, not `gitea.local`.
-
-**✅ Solution:** Use correct hostname (but prefer tea CLI)
-```bash
-curl http://localhost:3000/api/v1/repos/jihoson/The-Ouroboros/issues \
-  -H "Authorization: token $GITEA_TOKEN" \
-  -H "Content-Type: application/json" \
-  -d '{"title":"...", "body":"..."}'
-```
-
-**📝 Notes:**
- Prefer `tea` CLI over direct API calls
- Only use curl for operations tea doesn't support
-
-### Git Commands
-
-#### ❌ User Not Configured
-```bash
-git commit -m "message"
-# Error: Author identity unknown
-```
-**💡 Reason:** Git user.name and user.email not set.
-
-**✅ Solution:** Configure git user
-```bash
-git config user.name "agentson"
-git config user.email "agentson@localhost"
-```
-
-#### ❌ Permission Denied on Push
-```bash
-git push origin branch
-# Error: User permission denied for writing
-```
-**💡 Reason:** Repository access token lacks write permissions or user lacks repo write access.
-
-**✅ Solution:**
-1. Verify user has write access to repository (admin grants this)
-2. Ensure git credential has correct token with `write:repository` scope
-3. Check remote URL uses correct authentication
-
-### Python/Pytest
-
-#### ❌ Module Import Error
-```bash
-pytest tests/test_foo.py
-# ModuleNotFoundError: No module named 'src'
-```
-**💡 Reason:** Package not installed in development mode.
-
-**✅ Solution:** Install package with dev dependencies
 ```bash
+# Setup
 pip install -e ".[dev]"
+cp .env.example .env
+# Edit .env with your KIS and Gemini API credentials
+
+# Test
+pytest -v --cov=src
+
+# Run (paper trading)
+python -m src.main --mode=paper
 ```

-#### ❌ Async Test Hangs
-```python
-async def test_something():  # Hangs forever
-    result = await async_function()
-```
-**💡 Reason:** Missing pytest-asyncio or wrong configuration.
+## Documentation

-**✅ Solution:** Already configured in pyproject.toml
-```toml
-[tool.pytest.ini_options]
-asyncio_mode = "auto"
-```
-No decorator needed for async tests.

-## Architecture
+## Markets Supported

-Self-evolving AI trading agent for Korean stock markets (KIS API). The main loop in `src/main.py` orchestrates five components in a 60-second cycle per stock:
+- 🇰🇷 Korea (KRX)
+- 🇺🇸 United States (NASDAQ, NYSE, AMEX)
+- 🇯🇵 Japan (TSE)
+- 🇭🇰 Hong Kong (SEHK)
+- 🇨🇳 China (Shanghai, Shenzhen)
+- 🇻🇳 Vietnam (Hanoi, HCM)

-1. **Broker** (`src/broker/kis_api.py`) — Async KIS API client with automatic OAuth token refresh, leaky-bucket rate limiter (10 RPS), and POST body hash-key signing. Uses a custom SSL context with disabled hostname verification for the VTS (virtual trading) endpoint due to a known certificate mismatch.
+Markets auto-detected based on timezone and enabled in `ENABLED_MARKETS` env variable.

-2. **Brain** (`src/brain/gemini_client.py`) — Sends structured prompts to Google Gemini, parses JSON responses into `TradeDecision` objects. Forces HOLD when confidence < threshold (default 80). Falls back to safe HOLD on any parse/API error.
+## Critical Constraints

-3. **Risk Manager** (`src/core/risk_manager.py`) — **READ-ONLY by policy** (see `docs/agents.md`). Circuit breaker halts all trading via `SystemExit` when daily P&L drops below -3.0%. Fat-finger check rejects orders exceeding 30% of available cash.
+⚠️ **Non-Negotiable Rules** (see [docs/agents.md](docs/agents.md)):

-4. **Context Tree** (`src/context/`) — **NEW: Pillar 2 implementation.** 7-tier hierarchical memory (L1-L7) from real-time quotes to generational wisdom. Auto-aggregates daily → weekly → monthly → quarterly → annual → legacy. See [`docs/context-tree.md`](docs/context-tree.md) for details.
+- `src/core/risk_manager.py` is **READ-ONLY** — changes require human approval
+- Circuit breaker at -3.0% P&L — may only be made **stricter**
+- Fat-finger protection: max 30% of cash per order — always enforced
+- Confidence < 80 → force HOLD — cannot be weakened
+- All code changes → corresponding tests → coverage ≥ 80%

-5. **Evolution** (`src/evolution/optimizer.py`) — Analyzes high-confidence losing trades from SQLite, asks Gemini to generate new `BaseStrategy` subclasses, validates them by running the full pytest suite, and simulates PR creation.
+## Contributing

-**Data flow per cycle:** Fetch orderbook + balance → calculate P&L → query context tree → get Gemini decision → validate with risk manager → execute order → log to SQLite + context layers (`src/db.py`).
+See [docs/workflow.md](docs/workflow.md) for the complete development process.

-## Key Constraints (from `docs/agents.md`)
-
- `core/risk_manager.py` is **READ-ONLY**. Changes require human approval.
- Circuit breaker threshold (-3.0%) may only be made stricter, never relaxed.
- Fat-finger protection (30% max order size) must always be enforced.
- Confidence < 80 **must** force HOLD — this rule cannot be weakened.
- All code changes require corresponding tests. Coverage must stay >= 80%.
- Generated strategies must pass the full test suite before activation.
-
-## Configuration
-
-Pydantic Settings loaded from `.env` (see `.env.example`). Required vars: `KIS_APP_KEY`, `KIS_APP_SECRET`, `KIS_ACCOUNT_NO` (format `XXXXXXXX-XX`), `GEMINI_API_KEY`. Tests use in-memory SQLite (`DB_PATH=":memory:"`) and dummy credentials via `tests/conftest.py`.
-
-## Test Structure
-
-72 tests across five files. `asyncio_mode = "auto"` in pyproject.toml — async tests need no special decorator. The `settings` fixture in `conftest.py` provides safe defaults with test credentials and in-memory DB.
-
- `test_risk.py` (11) — Circuit breaker boundaries, fat-finger edge cases
- `test_broker.py` (6) — Token lifecycle, rate limiting, hash keys, network errors
- `test_brain.py` (18) — JSON parsing, confidence threshold, malformed responses, prompt construction
- `test_market_schedule.py` (19) — Market open/close logic, timezone handling, DST, lunch breaks
- `test_context.py` (18) — **NEW:** Context tree CRUD, aggregation logic, retention policies, layer metadata
+**TL;DR:**
+1. Create issue in Gitea
+2. Create feature branch: `feature/issue-N-description`
+3. Implement with tests
+4. Open PR
+5. Merge after review

+# System Architecture
+
+## Overview
+
+Self-evolving AI trading agent for global stock markets via KIS (Korea Investment & Securities) API. The main loop in `src/main.py` orchestrates four components in a 60-second cycle per stock across multiple markets.
+
+## Core Components
+
+### 1. Broker (`src/broker/`)
+
+**KISBroker** (`kis_api.py`) — Async KIS API client for domestic Korean market
+
+- Automatic OAuth token refresh (valid for 24 hours)
+- Leaky-bucket rate limiter (10 requests per second)
+- POST body hash-key signing for order authentication
+- Custom SSL context with disabled hostname verification for VTS (virtual trading) endpoint due to known certificate mismatch
+
+**OverseasBroker** (`overseas.py`) — KIS overseas stock API wrapper
+
+- Reuses KISBroker infrastructure (session, token, rate limiter) via composition
+- Supports 9 global markets: US (NASDAQ/NYSE/AMEX), Japan, Hong Kong, China (Shanghai/Shenzhen), Vietnam (Hanoi/HCM)
+- Different API endpoints for overseas price/balance/order operations
+
+**Market Schedule** (`src/markets/schedule.py`) — Timezone-aware market management
+
+- `MarketInfo` dataclass with timezone, trading hours, lunch breaks
+- Automatic DST handling via `zoneinfo.ZoneInfo`
+- `is_market_open()` checks weekends, trading hours, lunch breaks
+- `get_open_markets()` returns currently active markets
+- `get_next_market_open()` finds next market to open and when
+
+### 2. Brain (`src/brain/gemini_client.py`)
+
+**GeminiClient** — AI decision engine powered by Google Gemini
+
+- Constructs structured prompts from market data
+- Parses JSON responses into `TradeDecision` objects (`action`, `confidence`, `rationale`)
+- Forces HOLD when confidence < threshold (default 80)
+- Falls back to safe HOLD on any parse/API error
+- Handles markdown-wrapped JSON, malformed responses, invalid actions
+
+### 3. Risk Manager (`src/core/risk_manager.py`)
+
+**RiskManager** — Safety circuit breaker and order validation
+
+⚠️ **READ-ONLY by policy** (see [`docs/agents.md`](./agents.md))
+
+- **Circuit Breaker**: Halts all trading via `SystemExit` when daily P&L drops below -3.0%
+  - Threshold may only be made stricter, never relaxed
+  - Calculated as `(total_eval - purchase_total) / purchase_total * 100`
+- **Fat-Finger Protection**: Rejects orders exceeding 30% of available cash
+  - Must always be enforced, cannot be disabled
+
+### 4. Evolution (`src/evolution/optimizer.py`)
+
+**StrategyOptimizer** — Self-improvement loop
+
+- Analyzes high-confidence losing trades from SQLite
+- Asks Gemini to generate new `BaseStrategy` subclasses
+- Validates generated strategies by running full pytest suite
+- Simulates PR creation for human review
+- Only activates strategies that pass all tests

+KIS_APP_SECRET=your_app_secret
+KIS_ACCOUNT_NO=XXXXXXXX-XX
+GEMINI_API_KEY=your_gemini_key
+
+# Optional

+CONFIDENCE_THRESHOLD=80
+MAX_LOSS_PCT=3.0
+MAX_ORDER_PCT=30.0
+ENABLED_MARKETS=KR,US_NASDAQ  # Comma-separated market codes
+```
+
+Tests use in-memory SQLite (`DB_PATH=":memory:"`) and dummy credentials via `tests/conftest.py`.
+
+## Error Handling
+
+### Connection Errors (Broker API)
+- Retry with exponential backoff (2^attempt seconds)
+- Max 3 retries per stock
+- After exhaustion, skip stock and continue with next
+
+### API Quota Errors (Gemini)
+- Return safe HOLD decision with confidence=0
+- Log error but don't crash
+- Agent continues trading on next cycle
+
+### Circuit Breaker Tripped
+- Immediately halt via `SystemExit`
+- Log critical message
+- Requires manual intervention to restart
+
+### Market Closed
+- Wait until next market opens
+- Use `get_next_market_open()` to calculate wait time
+- Sleep until market open time

+tea issues create --body "text"
+# Error: flag provided but not defined: -body
+```
+**💡 Reason:** Parameter is `--description`, not `--body`.
+
+**✅ Solution:** Use correct parameter name
+```bash
+YES="" ~/bin/tea issues create --description "text"
+```
+
+### Gitea API (Direct HTTP Calls)
+
+#### ❌ Wrong Hostname
+```bash
+curl http://gitea.local:3000/api/v1/...
+# Error: Could not resolve host: gitea.local
+```
+**💡 Reason:** Gitea instance runs on `localhost:3000`, not `gitea.local`.
+
+**✅ Solution:** Use correct hostname (but prefer tea CLI)
+```bash
+curl http://localhost:3000/api/v1/repos/jihoson/The-Ouroboros/issues \
+  -H "Authorization: token $GITEA_TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{"title":"...", "body":"..."}'
+```
+
+**📝 Notes:**
+- Prefer `tea` CLI over direct API calls
+- Only use curl for operations tea doesn't support
+
+### Git Commands
+
+#### ❌ User Not Configured
+```bash
+git commit -m "message"
+# Error: Author identity unknown
+```
+**💡 Reason:** Git user.name and user.email not set.
+
+**✅ Solution:** Configure git user
+```bash
+git config user.name "agentson"
+git config user.email "agentson@localhost"
+```
+
+#### ❌ Permission Denied on Push
+```bash
+git push origin branch
+# Error: User permission denied for writing
+```
+**💡 Reason:** Repository access token lacks write permissions or user lacks repo write access.
+
+**✅ Solution:**
+1. Verify user has write access to repository (admin grants this)
+2. Ensure git credential has correct token with `write:repository` scope
+3. Check remote URL uses correct authentication
+
+### Python/Pytest
+
+#### ❌ Module Import Error
+```bash
+pytest tests/test_foo.py
+# ModuleNotFoundError: No module named 'src'
+```
+**💡 Reason:** Package not installed in development mode.
+
+**✅ Solution:** Install package with dev dependencies
+```bash
+pip install -e ".[dev]"
+```
+
+#### ❌ Async Test Hangs
+```python
+async def test_something():  # Hangs forever
+    result = await async_function()
+```
+**💡 Reason:** Missing pytest-asyncio or wrong configuration.
+
+**✅ Solution:** Already configured in pyproject.toml
+```toml
+[tool.pytest.ini_options]
+asyncio_mode = "auto"
+```
+No decorator needed for async tests.
+
+## Build & Test Commands
+
+```bash
+# Install all dependencies (production + dev)
+pip install -e ".[dev]"
+
+# Run full test suite with coverage
+pytest -v --cov=src --cov-report=term-missing
+
+# Run a single test file
+pytest tests/test_risk.py -v
+
+# Run a single test by name
+pytest tests/test_brain.py -k "test_parse_valid_json" -v
+
+# Lint
+ruff check src/ tests/
+
+# Type check (strict mode, non-blocking in CI)

+# Testing Guidelines
+
+## Test Structure
+
+**54 tests** across four files. `asyncio_mode = "auto"` in pyproject.toml — async tests need no special decorator.
+
+The `settings` fixture in `conftest.py` provides safe defaults with test credentials and in-memory DB.
+
+### Test Files
+
+#### `tests/test_risk.py` (11 tests)
+- Circuit breaker boundaries
+- Fat-finger edge cases
+- P&L calculation edge cases
+- Order validation logic
+
+**Example:**
+```python
+def test_circuit_breaker_exact_threshold(risk_manager):
+    """Circuit breaker should trip at exactly -3.0%."""
+    with pytest.raises(CircuitBreakerTripped):
+        risk_manager.validate_order(
+            current_pnl_pct=-3.0,
+            order_amount=1000,
+            total_cash=10000
+        )
+```
+
+#### `tests/test_broker.py` (6 tests)
+- OAuth token lifecycle
+- Rate limiting enforcement
+- Hash key generation
+- Network error handling
+- SSL context configuration
+
+**Example:**
+```python
+async def test_rate_limiter(broker):
+    """Rate limiter should delay requests to stay under 10 RPS."""
+    start = time.monotonic()
+    for _ in range(15):  # 15 requests
+        await broker._rate_limiter.acquire()
+    elapsed = time.monotonic() - start
+    assert elapsed >= 1.0  # Should take at least 1 second
+```
+
+#### `tests/test_brain.py` (18 tests)
+- Valid JSON parsing
+- Markdown-wrapped JSON handling
+- Malformed JSON fallback
+- Missing fields handling
+- Invalid action validation
+- Confidence threshold enforcement
+- Empty response handling
+- Prompt construction for different markets
+
+**Example:**
+```python
+async def test_confidence_below_threshold_forces_hold(brain):
+    """Decisions below confidence threshold should force HOLD."""
+    decision = brain.parse_response('{"action":"BUY","confidence":70,"rationale":"test"}')
+    assert decision.action == "HOLD"
+    assert decision.confidence == 70
+```
+
+#### `tests/test_market_schedule.py` (19 tests)
+- Market open/close logic
+- Timezone handling (UTC, Asia/Seoul, America/New_York, etc.)
+- DST (Daylight Saving Time) transitions
+- Weekend handling
+- Lunch break logic
+- Multiple market filtering
+- Next market open calculation
+
+**Example:**
+```python
+def test_is_market_open_during_trading_hours():
+    """Market should be open during regular trading hours."""
+    # KRX: 9:00-15:30 KST, no lunch break
+    market = MARKETS["KR"]
+    trading_time = datetime(2026, 2, 3, 10, 0, tzinfo=ZoneInfo("Asia/Seoul"))  # Monday 10:00
+    assert is_market_open(market, trading_time) is True
+```
+
+## Coverage Requirements
+
+**Minimum coverage: 80%**
+
+Check coverage:
+```bash
+pytest -v --cov=src --cov-report=term-missing
+```
+
+Expected output:
+```
+Name                          Stmts   Miss  Cover   Missing
+-----------------------------------------------------------
+src/brain/gemini_client.py       85      5    94%   165-169
+src/broker/kis_api.py           120     12    90%   ...
+src/core/risk_manager.py         35      2    94%   ...
+src/db.py                        25      1    96%   ...
+src/main.py                     150     80    47%   (excluded from CI)
+src/markets/schedule.py          95      3    97%   ...
+-----------------------------------------------------------
+TOTAL                           510     103   80%
+```
+
+**Note:** `main.py` has lower coverage as it contains the main loop which is tested via integration/manual testing.
+
+## Test Configuration
+
+### `pyproject.toml`
+```toml
+[tool.pytest.ini_options]
+asyncio_mode = "auto"
+testpaths = ["tests"]
+python_files = ["test_*.py"]
+```
+
+### `tests/conftest.py`
+```python
+@pytest.fixture
+def settings() -> Settings:
+    """Provide test settings with safe defaults."""
+    return Settings(
+        KIS_APP_KEY="test_key",
+        KIS_APP_SECRET="test_secret",
+        KIS_ACCOUNT_NO="12345678-01",
+        GEMINI_API_KEY="test_gemini_key",
+        MODE="paper",
+        DB_PATH=":memory:",  # In-memory SQLite
+        CONFIDENCE_THRESHOLD=80,
+        ENABLED_MARKETS="KR",
+    )
+```
+
+## Writing New Tests
+
+### Naming Convention
+- Test files: `test_<module>.py`
+- Test functions: `test_<feature>_<scenario>()`
+- Use descriptive names that explain what is being tested
+
+### Good Test Example
+```python
+async def test_send_order_with_market_price(broker, settings):
+    """Market orders should use price=0 and ORD_DVSN='01'."""
+    # Arrange
+    stock_code = "005930"
+    order_type = "BUY"
+    quantity = 10
+
+    # Act
+    with patch.object(broker._session, 'post') as mock_post:
+        mock_post.return_value.__aenter__.return_value.status = 200
+        mock_post.return_value.__aenter__.return_value.json = AsyncMock(
+            return_value={"rt_cd": "0", "msg1": "OK"}
+        )
+
+        await broker.send_order(stock_code, order_type, quantity, price=0)
+
+    # Assert
+    call_args = mock_post.call_args
+    body = call_args.kwargs['json']
+    assert body['ORD_DVSN'] == '01'  # Market order
+    assert body['ORD_UNPR'] == '0'   # Price 0
+```
+
+### Test Checklist
+- [ ] Test passes in isolation (`pytest tests/test_foo.py::test_bar -v`)
+- [ ] Test has clear docstring explaining what it tests
+- [ ] Arrange-Act-Assert structure
+- [ ] Uses appropriate fixtures from conftest.py
+- [ ] Mocks external dependencies (API calls, network)
+- [ ] Tests edge cases and error conditions
+- [ ] Doesn't rely on test execution order
+
+## Running Tests
+
+```bash
+# All tests
+pytest -v
+
+# Specific file
+pytest tests/test_risk.py -v
+
+# Specific test
+pytest tests/test_brain.py::test_parse_valid_json -v
+
+# With coverage
+pytest -v --cov=src --cov-report=term-missing
+
+# Stop on first failure
+pytest -x
+
+# Verbose output with print statements
+pytest -v -s
+```
+
+## CI/CD Integration
+
+Tests run automatically on:
+- Every commit to feature branches
+- Every PR to main
+- Scheduled daily runs
+
+**Blocking conditions:**
+- Test failures → PR blocked
+- Coverage < 80% → PR blocked (warning only for main.py)
+
+**Non-blocking:**
+- `mypy --strict` errors (type hints encouraged but not enforced)
+- `ruff check` warnings (must be acknowledged)

+# Development Workflow
+
+## Git Workflow Policy
+
+**CRITICAL: All code changes MUST follow this workflow. Direct pushes to `main` are ABSOLUTELY PROHIBITED.**
+
+1. **Create Gitea Issue First** — All features, bug fixes, and policy changes require a Gitea issue before any code is written
+2. **Create Feature Branch** — Branch from `main` using format `feature/issue-{N}-{short-description}`
+3. **Implement Changes** — Write code, tests, and documentation on the feature branch
+4. **Create Pull Request** — Submit PR to `main` branch referencing the issue number
+5. **Review & Merge** — After approval, merge via PR (squash or merge commit)
+
+**Never commit directly to `main`.** This policy applies to all changes, no exceptions.
+
+## Agent Workflow
+
+**Modern AI development leverages specialized agents for concurrent, efficient task execution.**
+
+### Parallel Execution Strategy
+
+Use **git worktree** or **subagents** (via the Task tool) to handle multiple requirements simultaneously:
+
+- Each task runs in independent context
+- Parallel branches for concurrent features
+- Isolated test environments prevent interference
+- Faster iteration with distributed workload
+
+### Specialized Agent Roles
+
+Deploy task-specific agents as needed instead of handling everything in the main conversation:
+
+- **Conversational Agent** (main) — Interface with user, coordinate other agents
+- **Ticket Management Agent** — Create/update Gitea issues, track task status
+- **Design Agent** — Architectural planning, RFC documents, API design
+- **Code Writing Agent** — Implementation following specs
+- **Testing Agent** — Write tests, verify coverage, run test suites
+- **Documentation Agent** — Update docs, docstrings, CLAUDE.md, README
+- **Review Agent** — Code review, lint checks, security audits
+- **Custom Agents** — Created dynamically for specialized tasks (performance analysis, migration scripts, etc.)
+
+### When to Use Agents
+
+**Prefer spawning specialized agents for:**
+
+1. Complex multi-file changes requiring exploration
+2. Tasks with clear, isolated scope (e.g., "write tests for module X")
+3. Parallel work streams (feature A + bugfix B simultaneously)
+4. Long-running analysis (codebase search, dependency audit)
+5. Tasks requiring different contexts (multiple git worktrees)
+
+**Use the main conversation for:**
+
+1. User interaction and clarification
+2. Quick single-file edits
+3. Coordinating agent work
+4. High-level decision making
+
+### Implementation
+
+```python
+# Example: Spawn parallel test and documentation agents
+task_tool(
+    subagent_type="general-purpose",
+    prompt="Write comprehensive tests for src/markets/schedule.py",
+    description="Write schedule tests"
+)
+
+task_tool(
+    subagent_type="general-purpose",
+    prompt="Update README.md with global market feature documentation",
+    description="Update README"
+)
+```
+
+Use `run_in_background=True` for independent tasks that don't block subsequent work.
