Standalone Rust binary implementing a mock ACP-compliant agent for testing +- Implements the full ACP protocol (initialize, authenticate, new_session, prompt, cancel) +- Provides configurable behavior via environment variables for test scenarios + +### How it fits into the larger codebase + +- Used by integration tests in `@/codex-rs/acp/tests/integration.rs` to test ACP protocol flow +- Used by TUI black-box tests in `@/codex-rs/tui-integration-tests` as the `--model mock-acp-agent` backend +- Enables end-to-end testing of `AgentProcess` without requiring real AI providers +- Produces diagnostic stderr output that tests use to verify stderr capture functionality +- Not shipped in production; exists solely for development and CI testing + +### Core Implementation + +**Entry Point:** `main()` in `@/mock-acp-agent/src/main.rs` + +- Uses `agent_client_protocol` crate for protocol implementation +- Runs on single-threaded tokio runtime with `LocalSet` for `!Send` futures +- Communicates via stdin/stdout with newline-delimited JSON-RPC messages + +**Protocol Methods:** + +| Method | Behavior | +|--------|----------| +| `initialize` | Returns mock capabilities, emits "Mock agent: initialize" to stderr | +| `new_session` | Generates incrementing session IDs | +| `prompt` | Sends two text chunks, optionally reads files via client | +| `cancel` | Sets flag to stop streaming | + +**Internal Architecture:** + +``` +┌─────────────────┐ ┌──────────────────┐ ┌─────────────────┐ +│ AgentSideConn │<--->│ MockAgent │<--->│ Channels │ +│ (I/O handling) │ │ (impl Agent) │ │ (updates/reqs) │ +└─────────────────┘ └──────────────────┘ └─────────────────┘ +``` + +### Things to Know + +**Environment Variables for Test Control:** + +| Variable | Effect | +|----------|--------| +| `MOCK_AGENT_HANG` | Sleeps 60s during initialize (timeout testing) | +| `MOCK_AGENT_REQUEST_FILE` | Reads file path via client during prompt | +| `MOCK_AGENT_STREAM_UNTIL_CANCEL` | Continuously streams until cancel notification | +| `MOCK_AGENT_STDERR_COUNT` | Emits N lines of `MOCK_AGENT_STDERR_LINE:{i}` to stderr during prompt | +| `MOCK_AGENT_RESPONSE` | Custom response text instead of default "Test message 1/2" (added for TUI testing) | +| `MOCK_AGENT_DELAY_MS` | Millisecond delay before completing stream to simulate realistic streaming (added for TUI testing) | + +**Stderr Output for Testing:** + +The agent writes to stderr at key points for observability: +- "Mock agent: initialize" on initialization +- "Mock agent: new_session id={id}" on session creation +- "Mock agent: prompt" on prompt request +- "Mock agent: cancel" on cancellation +- `MOCK_AGENT_STDERR_LINE:{i}` lines when `MOCK_AGENT_STDERR_COUNT` is set + +This allows tests to verify stderr capture by checking for known strings. + +**File Read Client Request:** + +The agent can request file reads from the client via `conn.read_text_file()`. This exercises bidirectional client<->agent communication. Set `MOCK_AGENT_REQUEST_FILE=/path/to/file` to trigger. + +**Binary Name:** + +Cargo renames hyphens to underscores in binary names, so the built artifact is `mock_acp_agent` (not `mock-acp-agent`).
