## Implementation Complete ### Changes Made **tests/mocks/mock_claude.py** - Complete rewrite with: - All ~40 CLI flags from real claude CLI: - Output: `-p/--print`, `--output-format`, `--input-format`, `--json-schema`, `--include-partial-messages` - Debug: `-d/--debug`, `--verbose`, `--mcp-debug` - Permissions: `--dangerously-skip-permissions`, `--allow-dangerously-skip-permissions`, `--permission-mode` - Tools: `--allowed-tools`, `--disallowed-tools`, `--tools` - Session: `-c/--continue`, `-r/--resume`, `--session-id`, `--fork-session`, `--no-session-persistence` - Model: `--model`, `--agent`, `--betas`, `--fallback-model` - MCP: `--mcp-config`, `--strict-mcp-config` - Prompts: `--system-prompt`, `--append-system-prompt` - Config: `--working-dir`, `--settings`, `--add-dir`, `--setting-sources` - Plugins: `--plugin-dir`, `--disable-slash-commands`, `--agents` - Integration: `--chrome`, `--no-chrome`, `--ide`, `--replay-user-messages` - Budget: `--max-budget-usd` - New environment variables: - `MOCK_CLAUDE_EXIT_CODE` - Simulate specific exit codes - `MOCK_CLAUDE_ERROR` - Simulate error messages - `MOCK_CLAUDE_PERMISSION` - Trigger permission request flow - `MOCK_CLAUDE_DELAY` - Control streaming delay (default: 0) - `MOCK_CLAUDE_RESPONSE` - Path to fixture file **tests/unit/test_mock_claude.py** - 61 comprehensive tests: - Basic functionality (exists, executable, help) - All CLI flags acceptance (45 parameterized tests) - Output formats (text, json, stream-json) - Fixture loading (simple, tool_use, permission) - Environment variable configuration - JSONL format validation **tests/fixtures/error_response.jsonl** - New error fixture **tests/conftest.py** - Added error_response_fixture **tests/mocks/__init__.py** - Added MOCK_CLAUDE_PATH export ### Test Results All 61 tests pass. ### QA Criteria Status - [x] Accepts same flags as real claude - [x] Returns JSONL output matching real format - [x] Can simulate streaming delays - [x] Can simulate permission request flow - [x] Can simulate errors/failures

## Feature Triage Complete **Status:** PARTIALLY IMPLEMENTED The file `tests/mocks/mock_claude.py` already exists (116 lines) with basic functionality: - Basic CLI argument parsing (--print, --model, --working-dir, --resume, --continue) - JSONL output format support - Custom response file loading via MOCK_CLAUDE_RESPONSE env var - Streaming simulation with configurable delays (MOCK_CLAUDE_DELAY) - Fixtures exist for: simple_response, tool_use, multi_turn, permission_request **What's Missing:** 1. ~30 additional CLI flags from real claude (--output-format, --permission-mode, --session-id, etc.) 2. Exit code simulation for error testing 3. Programmatic permission request triggering 4. Unit tests for the mock itself **Complexity:** low-medium (mostly argparse expansion) **Scope:** Enhance existing file + add 1-2 fixtures See full triage report at /tmp/triage-CLIAPI-32.md
