Use when given a GitHub Actions CI run link with test failures, when CI tests show TMT with retry-pass patterns, or when tests pass locally but timeout in CI
Use when writing or reviewing code that involves time — sleeps, timeouts, retry/backoff, deduplication windows, rate limits, cache TTLs, "wait until X", timing assertions, or any arithmetic over `SystemTime::now()` / `UnixTimestamp::now()` / `Instant::now()` / `tokio::time::sleep`. Decides whether to use monotonic (`Instant`) or wall-clock (`SystemTime`) and how to mix them safely.
Extract architectural and design decisions from a GitHub PR into ADR (Architecture Decision Record) files in design/docs/. Use this skill whenever the user wants to extract design decisions from a PR, create ADRs from PR discussions, document architectural choices from pull requests, or mentions "design extraction" or "design decisions" in the context of a PR. Also triggers for "extract ADRs", "document decisions from PR", or "pull design docs from PR".
Use when writing, modifying, or reading integration tests in crates/chain/tests/, or when needing to understand the IrysNodeTest harness, block production patterns, multi-node setups, or test synchronization utilities
