Automate GitLab project management, issues, merge requests, pipelines, branches, and user operations via Rube MCP (Composio). Always search tools first for current schemas.

[02] META. Create new skills when existing ones don't cover the task. Analyze unique requirements, build framework (Frame → Research → Plan → Execute), integrate risks, and declare new skill. Use when facing novel problems that existing skills can't address.

Release workflow for the Stave repository that confirms whether the next release is patch or minor before bumping the version, reviews the actual PR changes and PR description `Changes` sections in the release scope instead of relying on commit titles alone, generates release notes with `conventional-changelog`, and opens a pull request against `main` from a dedicated temporary release worktree so the user's original checkout stays on its original branch. Use when the user asks to cut the next release, ship the current changes as a versioned release, or prepare a release PR. After the PR merges, the repository's GitHub Actions workflow builds and publishes the release artifacts automatically.

Migrate to RevenueCat from raw StoreKit or Google Play Billing, or upgrade the RevenueCat SDK across a major version. Use when the user says migrate to RevenueCat, switch from StoreKit to RC, upgrade RevenueCat SDK, from v4 to v5, observer mode, RevenueCat major version upgrade, or already have in app purchases and want to add RevenueCat on iOS, Android, Kotlin Multiplatform, Flutter, or React Native.

End-to-end RevenueCat integration — sets up the dashboard side via the RevenueCat MCP (project, app, public API key) and installs/configures the Purchases SDK in the app. Use when the user asks to add RevenueCat, integrate Purchases, install the RevenueCat SDK, set up a RevenueCat API key, configure Purchases on launch, or set up a brand new RevenueCat integration on iOS, Android, Kotlin Multiplatform, Flutter, or React Native.

Tie RevenueCat identity to your app's auth system. Use when the user asks to log in to RevenueCat, sync a user with RevenueCat, switch RevenueCat user on login, log out of RevenueCat, move a user from anonymous to identified, set appUserID, or handle account switching on iOS, Android, Kotlin Multiplatform, Flutter, or React Native.

Defining and extracting kernel constants for syzkaller syzlang descriptions

Use when working on or reviewing session execution, command handling, shell state, FIFO-based streaming, or stdout/stderr separation. Relevant for session.ts, command handlers, exec/execStream, or anything involving shell process management. (project)

Create a new Cursor plugin scaffold with a valid manifest, component directories, and marketplace wiring. Use when starting a new plugin or adding a plugin to a multi-plugin repository.

Render a PR diff review as a Cursor Canvas that groups changes by reviewer importance, separates boilerplate from core logic, and highlights tricky or unexpected code. Use when reviewing a pull request, summarizing a diff for review, or when the user asks for a PR review canvas, diff walkthrough, or change-set overview.

Review CircleCI documentation pages for quality, clarity, and adherence to style guidelines. Use this skill whenever the user asks to review, audit, or assess documentation content, check for style compliance, evaluate page quality, or wants feedback on docs pages. Also trigger when the user mentions content quality, readability issues, or asks "how does this page look" or "is this page good." Even if they just reference a docs file path and ask for a review or feedback, use this skill.

Interview the user relentlessly about a plan or design until reaching shared understanding, resolving each branch of the decision tree. Use when user wants to stress-test a plan, get grilled on their design, or mentions "grill me".

Use when you need to design, review, or improve validation in Spring Boot applications — including Bean Validation on request DTOs, @Valid/@Validated at API boundaries, constraint groups, custom constraints, @ConfigurationProperties validation, nested DTO validation, and consistent validation error handling. This should trigger for requests such as Add validation support in Spring Boot; Review Spring Boot validation rules; Improve request validation in Spring Boot REST APIs; Add custom Bean Validation constraints in Spring Boot; Validate configuration properties in Spring Boot. Part of cursor-rules-java project

Guide secure migration of code from memory-unsafe languages (C, C++, Assembly) to memory-safe languages (Rust, Go, Java, C#, Swift). Use when migrating or rewriting legacy C/C++ code, designing FFI boundaries between safe and unsafe code, writing new modules in existing C/C++ codebases, reviewing mixed-language projects, planning memory safety roadmaps, or when an AI agent is about to generate new C/C++ code that could be written in a memory-safe language instead. Also triggers on CISA/NSA memory safety compliance discussions.

Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch for Claude Code or Cursor, update or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.

Validate n8n expression syntax and fix common errors. Use when writing n8n expressions, using {{}} syntax, accessing $json/$node variables, troubleshooting expression errors, mapping data between nodes, or referencing webhook data in workflows. Use this skill whenever configuring node fields that reference data from previous nodes — expressions are how n8n passes data between nodes, and getting the syntax wrong is the most common source of workflow errors. Also use when asked whether a complex expression hurts performance.

Summarizes B2B account health by analyzing usage patterns, engagement trends, risk signals, and expansion opportunities. Use for customer success reviews, renewal preparation, QBRs, or account prioritization.

Import a single webpage from any URL into canonical EDS block format — structured HTML that authors edit in DA. Scrapes the page, analyzes structure, maps to existing blocks, and generates HTML for immediate local preview. Also triggered by terms like "migrate", "migration", or "migrating". Use this when the goal is canonical EDS authoring; use the snowflake skill instead when the user wants to preserve the original DOM byte-for-byte (static-to-EDS overlay).

Use when authoring an agent skill that wraps a command-line tool — covers hands-on tool exploration, required vs. recommended sections, installation/usage structure, trigger-rich descriptions, task-grouped commands, progressive disclosure, and a pre-publish checklist. Triggers for CLI / command-line / terminal / shell-command tools and binary wrappers; for review, run the Checklist section.

Retrospective meta-skill for the `repo-visuals` skill. Reads accumulated evaluation logs from past runs, spots patterns (recurring low-score criteria, repeated iteration failures, unsatisfied requests), consults other expert skills (skill-creator, frontend-design, etc.) where relevant, and proposes concrete edits to `repo-visuals/SKILL.md` as a reviewable diff. Runs on-demand, not per run.
