From 26dc5192448c571b91edfb9c93fe927c252c5b93 Mon Sep 17 00:00:00 2001 From: Evan Senter Date: Sun, 18 Jan 2026 23:12:46 +0000 Subject: [PATCH 01/17] feat: expose agent as library with live integration tests - Refactor clemini from pure binary to library+binary architecture - Add src/lib.rs exposing AgentEvent, run_interaction, CleminiToolService - Move logging infrastructure to src/logging.rs with OutputSink trait - Add tests/confirmation_tests.rs with 4 live API tests: - test_destructive_command_requests_confirmation - test_confirmation_approval_executes_command - test_safe_command_no_confirmation - test_confirmation_response_is_semantic - Add semantic validation using Gemini structured output - Add serial_test dependency for global state tests Run live tests with: cargo test --test confirmation_tests -- --include-ignored Co-Authored-By: Claude Opus 4.5 --- Cargo.toml | 1 + Makefile | 4 +- src/agent.rs | 20 ++- src/events.rs | 4 +- src/lib.rs | 15 ++ src/logging.rs | 124 +++++++++++++++ src/main.rs | 129 +++------------- src/mcp.rs | 62 +++++--- src/tools/ask_user.rs | 5 +- src/tools/kill_shell.rs | 3 +- src/tools/todo_write.rs | 5 +- src/tools/web_search.rs | 1 + tests/common/mod.rs | 200 ++++++++++++++++++++++++ tests/confirmation_tests.rs | 295 ++++++++++++++++++++++++++++++++++++ 14 files changed, 716 insertions(+), 152 deletions(-) create mode 100644 src/lib.rs create mode 100644 src/logging.rs create mode 100644 tests/common/mod.rs create mode 100644 tests/confirmation_tests.rs diff --git a/Cargo.toml b/Cargo.toml index 4d41bca..1237a03 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -59,3 +59,4 @@ similar = "2" [dev-dependencies] tempfile = "3.10" mockito = "1.2" +serial_test = "3.1" diff --git a/Makefile b/Makefile index cb44b2a..48f17d0 100644 --- a/Makefile +++ b/Makefile @@ -13,7 +13,9 @@ release: cargo build --release test: - cargo test + cargo test --lib + cargo test --bin clemini + cargo test --test confirmation_tests clippy: cargo clippy -- -D warnings diff --git a/src/agent.rs b/src/agent.rs index 8ca3d4f..0c35d62 100644 --- a/src/agent.rs +++ b/src/agent.rs @@ -870,16 +870,20 @@ mod tests { "command": "rm /tmp/test", "message": "Confirm?" }); - assert!(result_with_confirmation - .get("needs_confirmation") - .and_then(|v| v.as_bool()) - .unwrap_or(false)); + assert!( + result_with_confirmation + .get("needs_confirmation") + .and_then(|v| v.as_bool()) + .unwrap_or(false) + ); // Test that normal results don't trigger it let normal_result = json!({"output": "success"}); - assert!(!normal_result - .get("needs_confirmation") - .and_then(|v| v.as_bool()) - .unwrap_or(false)); + assert!( + !normal_result + .get("needs_confirmation") + .and_then(|v| v.as_bool()) + .unwrap_or(false) + ); } } diff --git a/src/events.rs b/src/events.rs index c12d219..e26fc1a 100644 --- a/src/events.rs +++ b/src/events.rs @@ -30,7 +30,7 @@ use colored::Colorize; use serde_json::Value; use termimad::MadSkin; -use crate::log_event; +use crate::logging::log_event; // ============================================================================ // Markdown Rendering Infrastructure @@ -130,7 +130,7 @@ pub fn flush_streaming_buffer() -> Option { /// Used by EventHandlers after rendering with `render_streaming_chunk()`. pub fn write_to_streaming_log(rendered: &str) { // Skip logging during tests unless explicitly enabled - if !crate::is_logging_enabled() { + if !crate::logging::is_logging_enabled() { return; } diff --git a/src/lib.rs b/src/lib.rs new file mode 100644 index 0000000..ae1f1ff --- /dev/null +++ b/src/lib.rs @@ -0,0 +1,15 @@ +//!
