Testing & Quality skills

Browse reusable Agent Skills, each with a clear purpose and practical guidance.

debugging-difficult-bugs

Runtime-instrumentation debugging for bugs that static reading can't pin down — add temporary unconditional JSONL logging to the real code path, reproduce, read the log, then fix. Use when /root-cause lands at MEDIUM/LOW confidence, when a bug involves runtime state, ordering, caching, streaming, concurrency, or manual/UI reproduction, or before a second speculative fix. Skip when a stack trace or a deterministic failing test already proves the cause.

error

Capture a screenshot plus element snapshot of the current browser page when an error appears during e2e testing, saved to gitignored .ai/scratch/e2e/. Use whenever an agent-browser snapshot shows "Something went wrong", an auth error, a blank page, or an unexpected redirect. Building block — it captures and returns; the caller decides whether to continue.

root-cause

Read-only root-cause analysis for any bug, test failure, or unexpected behavior — before proposing or writing any fix. Produces a brief with the root cause, files to change, approach, and risks. No edits, no commits, no state-changing commands. Use before /fix or /conductor whenever the cause isn't already proven. If static reading can't reach a confident cause, it hands off to /debugging-difficult-bugs for runtime instrumentation.

ha-ios-testing

Unit and snapshot testing conventions. Use when writing tests, mocking dependencies by overriding Current, running the Tests-Unit scheme, or adding snapshot tests for new SwiftUI views.

poshi-migrate

Migrate a Liferay Poshi .testcase file to its modern test layer (Playwright, Jest, JUnit unit, Java integration). Routes each test to the right layer, consolidates compatible tests at write time, and follows existing Playwright patterns from a configurable reference folder. Use when the user asks to migrate, port, or convert a Poshi .testcase to Playwright, Jest, or JUnit.

poshi-shrink

Shrink a Liferay component's Poshi test suite by merging overlapping tests. Use when the user asks to reduce, merge, or clean up Poshi tests for a @component-name.

devchain

Help users run a local Ethereum dev chain, write integration tests, fork networks, debug transactions, or replace Hardhat/Anvil with Nethereum DevChain (.NET). Use this skill when the user mentions local Ethereum node, dev chain, test chain, Hardhat replacement, Anvil replacement, in-process blockchain, snapshot/revert, debug_traceTransaction, account impersonation, or anything involving a local EVM for development and testing with C# or .NET.

evm-simulation

Help users simulate Ethereum transactions, preview state changes, decode call trees, extract token transfers, decode revert reasons, debug EVM execution, or disassemble bytecode using Nethereum.EVM (.NET). Use this skill whenever the user mentions transaction simulation, transaction preview, state changes preview, call tracing, EVM debugging, bytecode execution, bytecode disassembly, opcode analysis, revert decoding, custom error decoding, ERC-20 simulation, balance change extraction, or anything involving local EVM execution with C# or .NET.

verified-state

Help users verify Ethereum state (balances, nonces, storage, code) without trusting their RPC provider using beacon chain light client proofs. Use this skill whenever the user mentions trustless queries, verified balances, light client verification, proof verification, Merkle proofs for state, eth_getProof, UseVerifiedState, VerifiedStateService, or wants to verify data from an RPC provider they don't trust.
