Pre-Merge Review Checklist

Before merging, verify these items. They represent the most common issues caught by automated code reviewers (Copilot, Gemini) on LunarWing PRs.

Database Operations

• Multi-step DB operations are wrapped in transactions (INSERT+INSERT, UPDATE+DELETE, read-modify-write)
• Both postgres AND libsql backends updated for any new Database trait methods
• Migrations are atomic (SQL execution + version recording in same transaction)

Security & Data Safety

• Tool parameters are redacted via redact_params() before logging or SSE/WebSocket broadcast
• URL validation resolves DNS before checking for private/loopback IPs (anti-SSRF via DNS rebinding)
• Destructive tools have requires_approval() returning Always or UnlessAutoApproved
• Data from worker containers is treated as untrusted (tool domain checks, server-side nesting depth)
• No secrets or credentials in error messages, logs, or SSE events

String Safety

• No byte-index slicing (&s[..n]) on external/user strings -- use is_char_boundary() or char_indices()
• File extension and media type comparisons are case-insensitive (.to_ascii_lowercase() before matching)
• Path comparisons are case-insensitive where needed (macOS/Windows filesystems)

Trait Wrappers & Decorator Chain

• New LlmProvider trait methods are delegated in ALL wrapper types (grep impl LlmProvider for)
• New trait methods are tested through the full decorator/provider chain, not just the base impl
• Default trait method implementations are intentional -- wrappers that silently return defaults are bugs

Tests

• Temporary files/dirs use tempfile crate, no hardcoded /tmp/ paths
• Tests don't mutate global statics without synchronization (use per-test state or serial_test)
• Tests don't make real network requests (use mocks, stubs, or RFC 5737 TEST-NET IPs like 192.0.2.1)
• Test names and comments match actual test behavior and assertions

Comments & Documentation

• Code comments match actual behavior (especially route paths, tool names, function semantics)
• Spec/README files updated if module behavior changed
• Error messages are clear and non-redundant (don't nest tool name inside tool error that already contains it)
