Generate a structured market research brief from a feature idea and supplied business context: market landscape, competitor intelligence, opportunity assessment, and a go-to-market recommendation. Use for market, research, competitor, and product launch requests.

Analyze product market positioning, competitive landscape, and unique value proposition. Use for positioning, market analysis, and differentiation.

Identify, categorize, and prioritize product launch risks, producing a risk matrix (probability × impact) with mitigation strategies. Use for launch risk, risk register, and go-to-market risk review.

Draft launch communications: an announcement / press release, an internal support FAQ, and a customer-facing feature summary. Use for launch comms, press release, announcement, and messaging.

Analyze an infrastructure incident alert and produce a structured response plan plus an executable on-call runbook. Use for incident, alert, on-call, and runbook requests.

Audit a vendor agreement or contract: extract key clauses, check that required clause categories are present, flag compliance gaps and risks, and emit a structured audit summary. Use for compliance, contract review, audit, and vendor agreement requests.

Produce a deep, structured research report on a topic: decompose into key dimensions, analyze each with evidence and reasoning, synthesize cross-cutting insights, and surface open questions. Use for deep research, analysis, and literature/landscape reviews.

Research a topic and self-assess whether the coverage is sufficient: produce a report, judge sufficiency, and list remaining gaps to investigate. Use for adaptive/agentic research and iterative investigation.

Use for concise business travel plans that combine policy constraints, local route facts, and traveler priorities.

Use for market-entry or go-to-market memos that combine CRM evidence, competitive signals, and executive decision needs.

Use for portfolio-facing stock risk briefs that separate market facts, interpretation, and non-investment-advice boundaries.

Prepare an evidence-backed blog/media interview preparation brief for a specified person by researching public context, reflecting on information sufficiency, and writing the final Markdown deliverable.

Guide for using Structural Search and Replace in IntelliJ. Use when creating or modifying SSR inspections or search patterns.

Guidelines for using the IntelliJ Registry API. Use when working with registry keys or feature flags.

Use when writing or modifying tests inside MPS `@tests` models — `NodesTestCase` (typesystem, constraints, scopes, dataflow, generator output), `EditorTestCase` (intentions, actions, keystrokes, side-transforms, completion), `MigrationTestCase` (migration scripts), `BTestCase` (plain JUnit on hand-written Java/Kotlin runtime), inline annotations such as `has error` / `has type` / `ScopesTest`, label-based `node<label>` cross-references, caret markers, and running tests via MCP / in MPS. Reach for this skill whenever the task involves authoring or fixing tests in a `tests`-stereotype model, or interpreting failures from one.

Create and execute IDE run configurations for MPS root nodes via MPS MCP — Java Application for `IMainClass` / `ClassConcept` with `main`, JUnit Tests for `ITestCase`. Use when launching DSL `main`-like roots, plain BaseLanguage `ClassConcept` mains, or MPS test cases from a node; reusing or replacing an existing run config; diagnosing `ClassNotFoundException`, `compileInMPS=false`, or "not runnable through this tool" failures.

Use when writing or debugging MPS quotations and anti-quotations — "node literals" that create SNode trees inline in behavior, typesystem, intentions, generator, and other model code. Covers heavy quotations (`Quotation`, `<...>`), light quotations (`NodeBuilder`, constructor-style for bootstrapping), and the four anti-quotation varieties: child (`%(...)%`), list (`*(...)*`), reference (`^(...)^`), property (`$(...)$`). Reach for this skill whenever the task involves splicing runtime values into quoted node trees or choosing between heavy and light quotations.

Add, update, or delete MPS nodes using JSON blueprints — covers the unified blueprint format, staged construction for large subtrees, validation, and reference repair. Use whenever creating, editing, or restructuring nodes in any MPS model (structure, editor, behavior, generator, application code, etc.).

Use when writing or editing MPS BaseLanguage code that lives inside a model — behavior methods, typesystem rules, checking rules, generator queries, constraints, intentions, scope/canBe callbacks, dataflow builders — and combines the `smodel`, `collections`, and `closures` language extensions. Covers querying nodes (`.descendants<C>`, `.ancestor<C>`, `.children`, `.parent`, `containingRoot`), filtering sequences (`.where`, `.select`, `.translate`, `.ofConcept<C>`), building closures (`{ it => ... }`, `yield`, recursion), creating and mutating nodes (`new node<C>()`, `add new(C)`, `set new(C)`, `replace with new(C)`, `.detach`, `.copy`), property and link access (`SPropertyAccess`, `SLinkAccess`, `SLinkListAccess`), reference operations (`.reference/C : role/`, `.target`), null-safe node equality (`:eq:` / `:ne:`), smodel/Java type casts (`node:C`, `node as C`, `/`, `downcast`), foreach choice, the `command` / `read action` lock wrappers, and JSON blueprints for every shape the Java parser cannot produce.

Complete JetBrains MPS workflow guide for DSL projects — models, languages, generators, node JSON blueprints, validation, MPS MCP tool usage, and the index of companion skills. Use whenever working in an MPS project, when AGENTS.md says to load the MPS workflow skill, or when you need to pick the right MPS aspect-specific skill.
