Help with Cairo's file-based golden test framework. Use /golden-tests for creating test runners, writing test files, or fixing test outputs.

Code review in the style of Ori Ziv (orizi). Reviews for correctness, simplicity, clean code, and performance. Catches unnecessary complexity, redundant code, naming issues, and architectural concerns. Use /orizi-review [file or PR] to review changed code.

Run pre-push checks and Orizi code review for Cairo repository

Run the apollo_network_benchmark P2P stress test end-to-end — gather parameters, start a local Docker or GKE cluster deployment, monitor it via Prometheus/Grafana, and summarize latency/throughput/delivery results. Use when the user says 'run the network benchmark', 'network stress test', 'apollo_network_benchmark', 'p2p benchmark', or wants to benchmark gossipsub/sqmr broadcasting.

Investigate why an Echonet resync triggered. Use when someone mentions an Echonet resync, a failing block in an `echonet-*` namespace, or a `block_hash_mismatch` / `transaction_commitment_mismatch` / `echonet_only_revert` / `gateway_error`. The skill sets up port-forwards, prefers GCP Logs Explorer for history, cross-checks the produced block against mainnet, and recognizes recurring failure patterns before reporting back.

Triage CI failures, flaky tests, and broken builds in the sequencer mono-repo. Use when a user mentions a failing CI job, flaky test, red check, or shares a GitHub Actions / PR URL — the skill pulls failure context directly from the public GitHub REST API so you can usually diagnose and report a verdict without asking the user any follow-up questions.

Split a large work-in-progress PR into a stack of small, reviewable PRs. Use this skill whenever the user mentions splitting a PR, stacking PRs, breaking up a large diff, making a PR easier to review, creating a PR stack, or decomposing changes into incremental commits. Also trigger when the user says things like "this PR is too big", "reviewers are struggling with this", or "I need to break this into smaller pieces". Works with any git-based project and any language.

Use when investigating errors, analyzing stack traces, or finding root causes of unexpected behavior. Invoke for error investigation, troubleshooting, log analysis, root cause analysis.
