Native `disabled` inherently communicates the state to assistive technologies and removes the element from the tab order. **Action:** When improving loading states for buttons, rely on the native `disabled` attribute and use `aria-busy={loading}` to inform screen readers of the active process without duplicating the disabled state. +## 2024-05-30 - Empty States Call-to-Action +**Learning:** Including an 'or try an example' call-to-action button that populates the input field solves the 'blank canvas' UX problem by explicitly demonstrating the expected input format to users. +**Action:** When designing empty states for text areas and generative tools, include an 'or try an example' call-to-action button that populates the input field. diff --git a/.jules/sentinel.md b/.jules/sentinel.md index 90031459..b0985041 100644 --- a/.jules/sentinel.md +++ b/.jules/sentinel.md @@ -68,3 +68,13 @@ **Vulnerability:** Information Exposure (CWE-200) in FastAPI error handling. An endpoint raised an `HTTPException` where the `detail` parameter was populated dynamically with the raw exception string (`str(exc)`). **Learning:** Returning `str(exc)` directly to the client can inadvertently expose sensitive internal paths, downstream API details, or error contexts meant only for developers. The exception must be logged securely on the backend while a sanitized generic message is returned to the user. **Prevention:** When raising `HTTPException` inside a `try...except` block, never pass the stringified exception `str(exc)` directly to the `detail` parameter. Instead, provide a generic, safe error message to the client, and rely on `logger.exception()` or explicit backend logging (e.g., `_log_repo_analyze_outcome`) to record the raw exception for internal troubleshooting. + +## 2024-05-20 - Ensure Environment Configuration for CORS is Testable +**Vulnerability:** Default local CORS allowed origins (`localhost:3000`) enabled by default without explicit environment checks. +**Learning:** Default configuration logic evaluated at module import (`os.environ.get`) is harder to test using standard pytest monkeypatch without using `importlib.reload()`, and defaults can expose unverified environments. +**Prevention:** Always scope permissive security defaults (like localhost origins) behind strict environment checks (e.g., `ENV == "development"`), and ensure proper mock-reloading when testing top-level variables. + +## 2025-05-30 - Prevent Command Injection via Custom Editor Wrappers +**Vulnerability:** The quick edit functionality in the CLI application manually parsed the `$EDITOR` environment variable and passed it to `subprocess.run()`, attempting to prevent malicious execution via a brittle blocklist of shells (`bash`, `python`, etc.). This was highly vulnerable to command injection and logic bypasses. +**Learning:** Custom command parsing and blocklisting for system interactions (like invoking an editor) is error-prone and often introduces "security theater". The standard library or established CLI frameworks usually have robust, platform-agnostic implementations. +**Prevention:** Use established security libraries/functions.
