Fetch, validate, triage, and address PR review comments from any reviewer — humans or automated bots. Core principle: skeptical triage, not blind compliance. Reviewers (especially bots) often lack cross-file context and project history — treat their suggestions as hints, not instructions. Read references/github-api-patterns.md for exact gh api commands, field names, and reply formats. Workflo...

Android Trace Sections — Perfetto-Backed Code Probes Why trace sections beat logging for performance Log.d answers “did this run.” Trace sections answer “did this run, on what thread, when, and how long” — with frame boundaries and other concurrent work in the same view. For any performance investigation that’s the difference between guessing and knowing. Question Loggin...

Android StrictMode Probe Why StrictMode catches what nothing else does StrictMode is the only built-in tool that fires for the silent killers — operations that don’t throw but ruin perceived performance: Disk I/O on the main thread Network calls on the main thread Leaked SQLite cursors, file streams, registered receivers Activity / fragment leaks Untagged sockets A Log.d probe w...

Android Snapshot Diff — Before / After State Capture Why diff snapshots Most “this isn’t working” symptoms boil down to one question: did anything actually change? The agent’s edit might not have hit the right code path. The fix might be a no-op. The dialog might be invisible but still in the hierarchy. The leak might be 2 KB or 200 KB. A diff between two snapshots gives a categorical answer...
