Identify latent bugs waiting to happen. | +| **P2** | **Diagnostics & Observability** | Errors must be visible, logged, and traceable. Silent failures are unacceptable. | +| **P3** | **Make Illegal States Unrepresentable** | Types should prevent bugs at compile-time. If invalid state can't exist, it can't cause bugs. | +| **P4** | **Single Responsibility** | Every function, class, module should do ONE thing.

A wrong comment is worse than no comment. | + +--- + +## Analysis Categories (1-10) + +Analyze the code against these 10 categories in priority order: + +### 1. Latent Bugs & Logic Risks (P1) - HIGHEST PRIORITY + +| Check | What to Look For | +|-------|------------------| +| **Logic fragility** | Conditionals that could break with edge cases, inverted logic risks | +| **Boundary conditions** | Off-by-one risks, empty/null inputs not handled, min/max value assumptions | +| **Missing preconditions** | Input validation gaps, domain rules not enforced, invariants not maintained | +| **State management risks** | Invalid state transitions possible, race condition windows, stale state scenarios | +| **Async hazards** | Missing awaits, unhandled promise rejections, order-of-execution assumptions | +| **Data transformation gaps** | Map/filter/reduce that could fail on edge cases, unsafe type conversions | +| **Arithmetic risks** | Overflow potential, precision loss scenarios, division by zero paths | +| **Determinism issues** | Time zone assumptions, locale dependencies, encoding assumptions | +| **Comparison hazards** | Reference vs value comparison confusion, floating point equality | +| **API assumption risks** | Response shape assumptions, missing field handling | + +### 2. Type Safety & Invariant Gaps (P3) + +| Check | What to Look For | +|-------|------------------| +| **Illegal states possible** | Can invalid states be constructed? Are invariants enforceable? | +| **Primitive obsession** | Using `string` everywhere instead of branded/nominal types | +| **Nullability inconsistency** | Inconsistent null/undefined handling, unsafe optional chaining | +| **Boolean blindness** | Using booleans where discriminated unions would prevent bugs | +| **Unvalidated boundaries** | `JSON.parse` without validation, untyped external data | +| **Encapsulation leaks** | Exposed mutables, public fields that could break invariants | +| **Schema drift risks** | API types that may not match actual responses | +| **Anemic types** | Data bags without behavior that should enforce rules | + +### 3. Observability & Diagnostics Gaps (P2) + +| Check | What to Look For | +|-------|------------------| +| **Silent failures** | Empty catch blocks, swallowed exceptions, catch-and-return-null | +| **Broad exception catching** | `catch (Exception e)` hiding unrelated errors | +| **Silent fallbacks** | Returning defaults without logging, user unaware of failure | +| **Logging gaps** | Missing context, no correlation IDs, no trace spans | +| **Error visibility** | Does the user know something went wrong? Actionable messages? | +| **Log level misuse** | Everything at INFO, no distinction between severity | +| **PII exposure risks** | Sensitive data potentially logged | +| **Health signal gaps** | Missing startup/readiness hooks, no health check endpoints | + +Anti-patterns to flag: +- `catch (e) { }` - Error vanishes +- `catch (e) { return null }` - Silent failure +- `catch (e) { return defaultValue }` - Hidden fallback without logging +- `data?.user?.settings?.theme ?? 'dark'` - Optional chaining hiding bugs +- `try { ...50 lines... } catch` - Can't tell what actually failed + +### 4. Resilience & Fault Tolerance Gaps (P9) + +| Check | What to Look For | +|-------|------------------| +| **Error taxonomy missing** | Retryable vs fatal not distinguished, transient vs permanent unclear | +| **Timeout gaps** | External calls without timeouts | +| **Retry risks** | No backoff, no max attempts, potential infinite retry | +| **Cascade failure risks** | No circuit breakers, fail-slow patterns | +| **Idempotency gaps** | Operations unsafe to retry, no idempotency keys | +| **Resource leak risks** | Missing finally/defer for connections, file handles, locks | +| **Transaction gaps** | Partial state possible, no clear commit/rollback | +| **Cancellation handling** | Not propagated through async chains | +| **Partial failure risks** | Batch operations don't handle individual failures | + +### 5.

A production bug is worse than ugly code that works. | +| **P2** | **Diagnostics & Observability** | Errors must be visible, logged, and traceable. Silent failures are unacceptable. | +| **P3** | **Make Illegal States Unrepresentable** | Types should prevent bugs at compile-time.

If you need "and" to describe it, split it. | +| **P5** | **Explicit Over Implicit** | Clarity beats cleverness. 3 readable lines > 1 clever line. No magic, no hidden behavior. | +| **P6** | **Minimal Surface Area** | Don't build for hypothetical futures. Solve today's problem today. YAGNI. | +| **P7** | **Prove It With Tests** | Untested code is unverified code. Tests prove correctness; coverage proves confidence. | +| **P8** | **Safe Evolution** | Public API/schema changes need migration paths. Internal changes can break freely. | +| **P9** | **Fault Containment** | Contain failures. One bad input shouldn't crash the system. Isolate concerns. | +| **P10** | **Comments Tell Why** | Comments explain reasoning, not mechanics.

It accepts file globs and prompts, runs asynchronously, and returns detailed insights after extended reasoning time. + +**Key advantages:** + +- Supports 100+ LLM providers through LiteLLM (OpenAI, Anthropic, Google, Azure, local models, etc.) +- Custom base URLs for any provider or local LLM server +- Automatic model discovery and selection +- Async operation with session management +- Token counting and context overflow protection +- Cross-platform Python implementation + +## Requirements + +The CLI uses [uv](https://docs.astral.sh/uv/) for automatic dependency management.
