Browse reusable Agent Skills, each with a clear purpose and practical guidance.
Run the full regression suite for the Compose dots indicators (logic + behaviour + golden screenshots) and relay any screenshot diffs to the agent for a visual verdict. Use after any change to the library's Compose indicators (Shift, Balloon, Spring, Worm), their positioning math, or RTL handling.
A/B test erigon's BAL parallel-execution scheduling on any BAL devnet (bal-devnet-N). Uses launch-devnet to bring up the primary instance, then spins up a second instance with IGNORE_BAL=true on a different port offset so throughput can be compared head-to-head. Use this when the user wants to compare BAL vs non-BAL parallel execution.
Re-execute all Ethereum blocks from block 0 to reproduce bugs, validate state, or test correctness after code changes. Use this skill whenever the user wants to re-run execution from scratch, reset execution stage, reproduce a state mismatch, validate a fix by re-exec, or run blocks from the beginning on a specific chain/datadir.
Run integrity checks on Erigon datadirs using the 'erigon seg integrity' command. Use this when the user wants to verify snapshot/segment file integrity or during the snapshot publishing process.
Run Erigon tests with Go race detector to find data races and concurrency bugs. Use this for concurrency-sensitive changes (parallel executor, p2p, txpool). Takes 30-60 minutes.
Run Erigon unit tests locally using make test-short. Use this for fast pre-push verification. Equivalent to the "Unit tests" CI workflow.
Integration test plan for erigondb.toml settings resolution across 3 runtime scenarios (legacy, fresh+downloader, fresh+no-downloader)
Run Ethereum Hive integration tests against a local Erigon build, including engine, RPC compatibility, standard EEST, BAL/Amsterdam EEST, and RLP suites. Use when setting up an ephemeral Hive environment, selecting or running Hive suites, interpreting Hive failures, or cleaning up Hive test resources.
