Inspect Playwright trace files from the command line — list actions, view requests, console, errors, snapshots and screenshots.

Run Rust benchmarks and compare performance with the C implementation. Use this when you work on migrating C code to Rust and want to ensure performance is not regressed.

Pull latest origin/main into the current local branch and resolve merge conflicts (aka update-branch). Use when Codex needs to sync a feature branch with origin, perform a merge-based update (not rebase), and guide conflict resolution best practices.

Evaluate the quality and efficacy of existing tests by reviewing test code against source code. Use when the user asks to review tests, validate test quality, audit test suites, check test efficacy, or assess whether tests are testing things properly. Prioritizes real interactions over mocking and simulation.

This skill should be used when building, modifying, or debugging a react-admin application — including creating resources, lists, forms, data fetching, authentication, relationships between entities, custom pages, or any CRUD admin interface built with react-admin.

Use when you need to add or evaluate Maven dependencies that improve code quality or domain modeling — including nullness annotations (JSpecify), static analysis (Error Prone + NullAway), functional programming (VAVR), architecture testing (ArchUnit), or money and currency support (JavaMoney) — and want a consultative, question-driven approach that adds only what you actually need. This should trigger for requests such as Add Maven dependencies; Add JSpecify nullness dependencies; Add Error Prone NullAway dependencies; Add VAVR functional dependencies; Add ArchUnit architecture testing dependencies; Add JavaMoney dependencies.

Use when creating or updating OpenSpec artifacts from an issue, plan, approved design, ADRs, existing OpenSpec, or a valid combination. The workflow assesses reviewable scope, records source authority and derivation, handles conflicts, and prevents silent synchronization. Triggers include Create OpenSpec from an issue; Convert a plan into OpenSpec; Update an OpenSpec change; Split broad requirements into reviewable changes. Part of Plinth Toolkit

To implement features, fix bugs, and refactor with KISS/SOLID/DRY and systematic validation.

Create or reuse a git worktree for a pull request or branch so reviews and work happen in isolation

Enforces dlt docstring conventions. Use when writing or modifying docstrings, classes, or function signatures in Python files.

Develop Lakeflow Spark Declarative Pipelines (formerly Delta Live Tables) on Databricks. Use when building batch or streaming data pipelines with Python or SQL. Invoke BEFORE starting implementation.

Orchestrates the complete Falcon Foundry app lifecycle from requirements through deployment. TRIGGER when user asks to "create a Foundry app", "build a Foundry app", "plan a Foundry app", runs any `foundry apps` CLI command, or discusses Foundry app architecture. DO NOT TRIGGER when user is working on a specific capability (UI, function, workflow, collection) within an existing app — use the appropriate sub-skill instead. This skill OWNS the entire Foundry development flow. Do not delegate Foundry app creation to superpowers:brainstorming or superpowers:writing-plans — those skills do not know about the Foundry CLI.

Detect CI runner underutilization and recommend downsizing for cost savings. Use when asked about CI costs, runner sizing, resource waste, underutilization, or right-sizing self-hosted runners.

Generate Git commit messages from staged changes when requested.

Generate Midjourney prompts for 600x600 card news background images based on topic, mood, and style preferences. Use when user requests card news backgrounds or Instagram post backgrounds.

Build SkyWalking OAP server, run javadoc checks, and verify checkstyle. Use to validate changes before submitting a PR.

Download and inspect CI e2e test logs from GitHub Actions artifacts. Use when investigating e2e test failures in CI.

Generate Nginx reverse proxy configurations with SSL/TLS (Let's Encrypt), static file serving, upstream definitions, rate limiting, gzip compression, security headers, and location blocks.

Generate optimized, multi-stage Dockerfiles for Node.js, Python, Go, Rust, and Java with layer caching, non-root users, and minimal production images.

Generate project handover documentation for AEM Edge Delivery Services projects. Creates comprehensive guides for content authors, developers, and administrators. Use for "handover docs", "project documentation", "generate handover", "create guides".
