It merges responsibilities previously split across multiple modules. +The BackendConnector manages adapter lifecycle, the backend message consumption loop, and passthrough interception. **Responsibilities:** -- **Connect:** Resolve the adapter via `AdapterResolver`, call `adapter.connect()`, hand the resulting `BackendSession` to the runtime via `runtime.setBackendSession()`, and start the consumption loop -- **Disconnect:** Call `runtime.clearBackendSession()` with disconnect reason -- **Consumption loop:** `for await (msg of backendSession.messages)` — for each message, touch activity timestamp, check passthrough interception, then call `runtime.handleBackendMessage(msg)` -- **Passthrough registration + interception (co-located):** When `SlashCommandService` issues a passthrough, `BackendConnector` registers it on the runtime and sends the command as a user message to the backend. During the consumption loop, it intercepts matching responses, buffers text, and emits the `slash_command_result` when complete — skipping the normal runtime routing for those messages -- **Stop adapters:** Call `AdapterResolver.stopAll?.()` for graceful shutdown (prevents orphan adapter-managed processes) -- **Stream end handling:** When the async iterable ends, call `runtime.handleBackendStreamEnd()` to trigger disconnection domain events +- **Connect:** Resolve the adapter, call `adapter.connect()`, call `runtime.attachBackendConnection()` with the `BackendSession`, start the consumption loop. The coordinator then emits `BACKEND_CONNECTED` signal to the runtime +- **Disconnect:** Routes as `process({ type: 'SYSTEM_SIGNAL', signal: { kind: 'BACKEND_DISCONNECTED', reason } })` +- **Consumption loop:** `for await (msg of backendSession.messages)` — for each message, routes as `process({ type: 'BACKEND_MESSAGE', message: msg })` +- **Passthrough interception:** Intercept matching slash command responses during the consumption loop +- **Stop adapters:** Call `AdapterResolver.stopAll?.()` for graceful shutdown **Inverted connection path (CLI calls back via WebSocket):** - `SessionTransportHub` routes `/ws/cli/:sessionId` callbacks to `CliGateway` -- `CliGateway` validates launch state, resolves an inverted adapter, and creates a proxy via `BufferedWebSocket` -- `BufferedWebSocket` buffers early inbound CLI messages until the adapter registers its first `message` handler, then replays exactly once in order -- After `bridge.connectBackend(sessionId)` succeeds, `adapter.deliverSocket(...)` receives the proxied socket +- `CliGateway` validates launch state, resolves an inverted adapter +- `BufferedWebSocket` buffers early inbound messages until the adapter registers its handler **Does NOT do:** -- Own adapter implementation details (that's each `BackendAdapter`) -- Decide what to do with messages (that's the runtime) +- Own adapter implementation details +- Decide what to do with messages (the reducer does) - Know about consumer WebSockets --- -## Message Plane - -### SlashCommandService - -**File:** `src/core/slash/slash-command-service.ts` (~70 lines, chain in `slash-command-chain.ts` ~394 lines, executor ~104 lines, registry ~176 lines) -**Context:** MessagePlane -**Writes state:** No (calls runtime/connector methods) - -The SlashCommandService provides a single `execute()` entrypoint for all slash command handling with a chain-of-responsibility strategy pattern.

engineering is not merely about writing code that works; it is about creating systems that are maintainable, scalable, secure, and resilient. As software increases in complexity, adhering to established best practices becomes the dividing line between a project that thrives and one that collapses under its own weight (technical debt). This essay explores the foundational pillars of modern software engineering: Code Quality, Architecture, Testing, Processes, and Security. + +## 1. Code Quality and Maintainability + +### 1.1 Readability as the Primary Metric +Code is read far more often than it is written. "Clever" code that obscures intent is a liability. +- **Naming Conventions:** Variables and functions should be self-documenting (e.g., `calculateTotalRevenue()` vs `calc()`). +- **Small Functions:** Functions should do one thing and do it well (Single Responsibility Principle). +- **Comments:** Comments should explain *why* something is done, not *what* is done. The code itself should explain the *what*. + +### 1.2 The DRY Principle (Don't Repeat Yourself) +Duplication leads to inconsistency. If logic is copied in three places, a bug fix must be applied three times. Abstraction and modularity allow for single sources of truth. + +### 1.3 SOLID Principles +- **S**ingle Responsibility: A class should have one reason to change. +- **O**pen/Closed: Open for extension, closed for modification. +- **L**iskov Substitution: Subtypes must be substitutable for their base types. +- **I**nterface Segregation: Many client-specific interfaces are better than one general-purpose interface. +- **D**ependency Inversion: Depend on abstractions, not concretions. + +## 2. Architectural Integrity + +### 2.1 Modularity and Decoupling +Systems should be composed of loosely coupled components. Changes in a UI module should not break the database layer. This is achieved through clear boundaries, interfaces, and dependency injection. + +### 2.2 Scalability +- **Horizontal vs. Vertical:** Design systems that can scale out (adding more machines) rather than just up (adding more power). +- **Statelessness:** Stateless services are easier to scale and recover from failures. + +### 2.3 Simplicity (KISS) +Complexity is the enemy of security and reliability. Avoid over-engineering. "You Aren't Gonna Need It" (YAGNI) reminds us to implement only what is necessary for current requirements, not future hypotheticals. + +## 3. Testing Strategies + +### 3.1 The Testing Pyramid +- **Unit Tests:** The base. Fast, isolated, and numerous. They test individual functions or classes. +- **Integration Tests:** Verify that different modules work together correctly. +- **End-to-End (E2E) Tests:** The tip. Slower and more brittle, simulating real user scenarios. + +### 3.2 Test-Driven Development (TDD) +Writing tests *before* implementation clarifies requirements and ensures testability. It leads to better API design and higher confidence in refactoring. + +## 4. Engineering Processes + +### 4.1 Version Control and Branching +- Use feature branches. +- Commit often with atomic, descriptive messages. +- Never rewrite public history. + +### 4.2 Code Reviews +Code reviews are for knowledge sharing and quality assurance, not just finding bugs. They ensure consistency and help junior engineers learn from seniors. + +### 4.3 CI/CD (Continuous Integration/Continuous Deployment) +Automate everything. +- **CI:** Automatically build and test every commit to detect regressions immediately. +- **CD:** Automate the release process to ensure reliable, repeatable deployments. + +## 5. Security by Design + +Security is not an add-on; it must be integral to the lifecycle. +- **Least Privilege:** Components should only have the permissions they absolutely need. +- **Input Validation:** Never trust user input. Sanitize and validate at the boundary. +- **Dependency Management:** Regularly scan and update third-party libraries to patch vulnerabilities. + +## 6. Documentation + +Documentation is the map for future maintainers. +- **Codebase Documentation:** Architecture diagrams, setup guides (`README.md`), and API specs. +- **Self-Documenting Code:** Clear types and naming reduce the need for external docs. +- **ADRs (Architecture Decision Records):** Document *why* a major technical decision was made to provide context for future teams. + +## Conclusion + +Best practices are not rigid laws but guidelines forged from decades of collective industry failure and success. Following them reduces the cognitive load on developers, minimizes bugs, and creates software that delivers value consistently over time. The goal is professional craftsmanship: writing code that you would be proud to hand over to another engineer. diff --git a/scripts/e2e-parity-gate.mjs b/scripts/e2e-parity-gate.mjs index 12e38b24..bbe862b2 100644 --- a/scripts/e2e-parity-gate.mjs +++ b/scripts/e2e-parity-gate.mjs @@ -17,7 +17,7 @@ const REQUIRED_TEST_FILES = [ "src/core/coordinator/session-lifecycle.integration.test.ts", "src/core/coordinator/session-status.integration.test.ts", "src/core/coordinator/streaming-conversation.integration.test.ts", - "src/core/bridge/permission-flow.integration.test.ts", + "src/core/coordinator/permission-flow.integration.test.ts", "src/core/consumer/presence-rbac.integration.test.ts", "src/core/session/message-queue.integration.test.ts", "src/server/ws-server-flow.integration.test.ts", diff --git a/src/adapters/acp/outbound-translator.test.ts b/src/adapters/acp/outbound-translator.test.ts index 310a6550..b489839b 100644 --- a/src/adapters/acp/outbound-translator.test.ts +++ b/src/adapters/acp/outbound-translator.test.ts @@ -204,9 +204,7 @@ describe("translateSessionUpdate", () => { sessionUpdate: "tool_call_update", toolCallId: "call-1", status: "completed", - content: [ - { type: "text", text: "result text" }, - ] as unknown as AcpSessionUpdate["content"], + content: [{ type: "text", text: "result text" }] as unknown as AcpSessionUpdate["content"], };
