Development
Structured software development workflow orchestrator using Spec-Driven Development (SDD). Transforms vague requirements into spec.md → tasks.md → implementation → verification. Triggers on: '开发功能', '实现这个', 'build this feature', 'implement', 'add new module', 'fix bug', 'develop', 'create feature'.
Review and merge open Dependabot PRs in the current workspace repo: changelog triage, risk classification, CI verification, and rebase merge. Use for "/review dependabot" or similar — always scoped to the repo you have open. Scheduled Bun/GitHub Actions/Docker bumps, grouped patches, security updates, semver-major upgrades.
Ties a GitHub pull request or GitLab merge request to an RHDH Jira issue in RHIDP, RHDHPLAN, RHDHBUGS, or RHDHSUPP: attach the Jira Web link titled `repo #N: <title>`, post or update the structured comment, fill empty issue fields, move an RHDHPLAN Epic, Story, or Task to RHIDP, and mark a Web link merged or closed. Raises the PR or MR first when one does not exist yet. Use for "link this PR to RHIDP-1234", "attach the MR to the Jira issue", "mark the Web links merged", "mark closed PRs", replacing a hand-rolled remotelink or comment step, or a PR outside the rhdh-plugins and community-plugins monorepo flow. The full monorepo flow — build, changeset, recordings — is rhdh-pr-create.
Guide for writing idiomatic Rust code based on Apollo GraphQL's best practices handbook. Use this skill when: (1) writing new Rust code or functions, (2) reviewing or refactoring existing code, (3) deciding between borrowing vs cloning or ownership patterns, (4) implementing error handling with Result types, (5) optimizing Rust code for performance, (6) writing tests or documentation for Rust projects
Build and review bracket-lib style Rust 2D game loops, state structs, game modes, input handling, rendering calls, and restart flow. Use when creating a small Rust game with bracket-lib, porting a tutorial loop, or debugging tick/update/render state behavior.
Plan small, playable Rust game implementation slices from a short design brief, MVP, stretch goals, and acceptance checks. Use when starting a Rust game, scoping a prototype, converting a game idea into work items, or preventing an AI coding agent from overbuilding.
Design and review Rust ECS gameplay code using Legion-style entities, components, resources, systems, schedules, queries, command buffers, and spawners. Use when building ECS-driven Rust game features, migrating game state into ECS, or debugging system ordering and component composition.
This skill should be used when users request code review, refactoring, or code quality improvements for Ruby codebases. Apply Sandi Metz's four rules for writing maintainable object-oriented code - classes under 100 lines, methods under 5 lines, no more than 4 parameters, and controllers instantiate only one object. Use when users mention "Sandi Metz", "code quality", "refactoring", or when reviewing Ruby code for maintainability.
Covers classical machine learning in Python with scikit-learn (sklearn): classification and regression estimators, clustering and dimensionality reduction, preprocessing, Pipeline and ColumnTransformer, cross-validation, metrics, and GridSearchCV hyperparameter tuning. Use when training or comparing classifiers and regressors on tabular or text data, clustering data and choosing the cluster count, building leakage-free preprocessing pipelines, evaluating models with cross-validation and metrics, or tuning hyperparameters. Not for deep learning; use a dedicated neural network framework instead.
SDD step 2 (optional, repeatable). Read an existing feature.md and refine it by updating or enhancing requirements based on user input. Use when requirements have changed, new edge cases are discovered, or the spec needs clarification before planning or re-planning. Run before /sdd-plan if plan.md already exists.
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)
Automate shepherding, checking status, updating branches, and landing open PRs or approved third-party contributor PRs in the flutter/flutter repository using the gh CLI. When to use: - When you need to check the status of open PRs or shepherded third-party PRs. - When you need to update stale branches or apply the 'autosubmit' label to land approved PRs. When not to use: - Do not use for PRs that are not approved (unless they are your own and you want to check status). - Do not use for repositories other than flutter/flutter.
Use this skill for all GitHub write operations in creative-graphic-design organization repositories (such as design-generators), including git commits and pushes, PR creation and updates, issue and PR comments, labels, milestones, and user-requested merges. Perform them as the creative-graphic-design-dev machine user. Use it both when the user explicitly requests the bot or dev account and whenever beginning write work in a creative-graphic-design organization repository without an explicit request; never use it in repositories of any other organization or host.
Use this skill when converting custom PyTorch models to Hugging Face Transformers format. Helps with: (1) Creating PretrainedConfig and PreTrainedModel classes, (2) Writing ImageProcessor/Tokenizer, (3) Compatibility testing, (4) Hub upload preparation. Use when the user wants to make their model compatible with transformers library.
AI-assisted debugging specialist with deep knowledge of modern debugging tools, observability platforms, and automated root cause analysis. Implements Cursor Debug Mode methodology — structured hypothesis ranking, targeted code instrumentation, human-in-the-loop reproduction gate, log-confirmed root cause, and mandatory cleanup.
Use when you need to execute I2 (implementation execution) in the sdlc-dev Spec Pack: implement in batches with `{FEATURE_DIR}/implementation/plan.md` as the single SSOT, run minimal verification, write back audit information, and report at batch checkpoints; stop immediately on blockers or open questions.
Use when the user asks to confirm feature trade-offs in a PRD or development plan item by item; not for quality reviews, writing documents from scratch, or implementation. Briefly explain each feature, its value, and the planned approach; revise the document after confirmation, rejection, or changes
Create, update, or supersede a project glossary in the Spec Loop AsciiDoc glossary format. Use when the user, project instructions, or `spec-loop-plan-task` already requires project glossary work. This skill is mandatory for AsciiDoc project glossaries unless the user explicitly opts out for the current project or session.
Verifies whether code follows Spring Modulith code structure or not. Show list of violations along with recommendations on how to fix them. Use this skill: * When reviewing Spring Boot applications which uses Spring Modulith * When verifying whether Spring Boot application code follows Spring Modulith package structure
Always invoke to review, repair, or deliver geospatial or GeoAI code, including contract compliance, security, error handling, transactions, tests, scripts, functions, notebooks, packages, CI/CD, and repository changes, even when deployment is not requested. Pair with the domain skill for ETL and other production code. Covers CRS/data invariants, dependencies, cross-platform reproducibility, automation, and shipping. Do not trigger for unrelated software or analysis requesting no code or repository artifact.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
