Unslopcursor/pluginsCut AI tells from any writing. Must always apply.4631Thermo Nuclear Code Quality Reviewcursor/pluginsRun an extremely strict maintainability review for abstraction quality, giant files, and spaghetti-condition growth. Use for a thermo-nuclear code quality review, thermonuclear review, deep code quality audit, or especially harsh maintainability review.2401Architectcursor/pluginsSketch types, signatures, and module structure before code, then stay in the loop while implementation fills in. Use for /architect, 'architect this', 'design this', or non-trivial work where jumping to code would lock in the wrong shape.04Arenacursor/pluginsSpawn N parallel candidates at the same task, pick a base, graft the strongest parts of the losers into it. Use for /arena, 'arena this', 'throw it in the arena', or when one attempt at a non-trivial artifact would lock in the wrong shape.01Automate Mecursor/pluginsUse for \"automate me\", \"create/update/refresh my -mode skill\", \"turn/capture my preferences or working style into a skill\", or wanting agents to follow how the user works. Drafts or revises a personal -mode skill via create-skill + unslop, optionally pulling fresh evidence from recent transcripts.01Blast Radiuscursor/pluginsFind what a change could break somewhere else before it ships, beyond the diff, and prove the one fact it's safe because of by running real code instead of writing it up. Use for 'blast radius of X', 'what could this break', or reviewing a small diff you don't trust.01Brocursor/pluginsRestate the last message in plain human language, with no jargon.01Cancel Ralphcursor/pluginsCancel an active Ralph Loop. Use when the user wants to stop, cancel, or abort a running ralph loop.01Check Compiler Errorscursor/pluginsRun compile and type-check commands and report failures01CLI For Agentscursor/plugins>-01Continual Learningcursor/pluginsOrchestrate continual learning by delegating transcript mining and AGENTS.md updates to `agents-memory-updater`.01Control CLIcursor/pluginsBuild or adapt a local harness to drive, inspect, and profile an interactive CLI or TUI without external services. Use for CLI UX checks, startup regressions, memory leaks, hangs, prompt flows, or terminal demos.01Control UIcursor/pluginsBuild or adapt a local browser/CDP harness to drive and inspect a web, IDE, or Electron UI. Use for local UI verification, screenshots, accessibility snapshots, perf profiles, visual diffs, or reproducing UI bugs.01Create Learning Pathcursor/pluginsBuild a personalized learning roadmap with milestones and practice checkpoints01Create Plugin Scaffoldcursor/pluginsCreate 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.01Create Verification Skillcursor/pluginsGenerate a project-local verification skill that drives your app the way a user does — any language, framework, or platform. Use for /create-verification-skill, \"make a control skill for this repo\", or when a project has no scripted way to prove UI/CLI/service behavior.04Cursor SDKcursor/pluginsGuide users building apps, scripts, CI pipelines, or automations on top of the Cursor TypeScript SDK (`@cursor/sdk`). Use this skill whenever the user mentions integrating, installing, or writing code against the Cursor SDK; whenever they say `Agent.create`, `Agent.prompt`, `Agent.resume`, `agent.send`, `run.stream`, `CursorAgentError`, or `@cursor/sdk`; whenever they ask to run Cursor agents programmatically from a script, CI/CD pipeline, GitHub Action, backend service, or any other code that isn't the Cursor IDE itself; and whenever they want to pick between local and cloud runtime, configure MCP servers for an SDK agent, or handle streaming, cancellation, or errors from an SDK agent. Also trigger when a user is wiring Cursor into an automation, writing a bot that runs Cursor, or porting REST `/v1/agents` calls to the SDK, even if they don't explicitly name the package. Use this eagerly rather than answering from memory; the SDK surface evolves and this skill plus its references are the source of truth for the external package.08Deslopcursor/pluginsRemove AI-generated code slop and clean up code style01Docs Canvascursor/plugins>-01Figure It Outcursor/pluginsDesign an auditable playbook when no narrower one fits: a large migration, an ambitious multi-part change, or work a human reviews after stepping away. Scales rigor to the task, runs a hypothesis loop, and logs decisions via show-me-your-work. Use for /figure-it-out, 'figure it out', a large migration, or when no narrower playbook applies.01Fix CIcursor/pluginsFind failing PR checks, inspect logs or external check links, and apply focused fixes01Fix Merge Conflictscursor/pluginsResolve merge conflicts non-interactively, validate build and tests, and finalize conflict resolution01Get PR Commentscursor/pluginsFetch and summarize review comments from the active pull request01Howcursor/pluginsUse for \"how does X work\", code walkthroughs before changing something, and placement / ownership / layering questions (\"where should this live\", \"which package owns this\", \"is this the right layer\"). Explains subsystem architecture, runtime flow, onboarding mental models. Use why for motivation.03Interrogatecursor/pluginsUse for \"interrogate\", \"adversarial review\", \"multi-model review\", \"challenge this\", \"stress test this code\", \"find blind spots\", or \"tear this apart\". Multiple LLM reviewers challenge changes from independent angles.05Loop On CIcursor/pluginsMonitor PR checks and fix failures until green. Uses gh pr checks as the source of truth for PR-attached checks.01Maintain Verification Skillcursor/pluginsPeriodic pass that keeps a project's verification skill and feature map honest: parallel source readers per feature, one live session driving every feature, at most one PR of proven corrections. Use for /maintain-verification-skill or \"audit the verify skill\".01Make Bot UIcursor/plugins>-01Make PR Easy To Reviewcursor/pluginsPrepare PRs for review by cleaning noisy history, improving PR descriptions, and adding reviewer guidance without changing code behavior. Use for "make this easy to review", "tidy this PR", "clean up commits", or "annotate the diff".01New Branch And PRcursor/pluginsCreate a fresh branch, complete work, and open a pull request01No Commentscursor/pluginsSpawn Comment Sicko, fix accepted findings, and offer encodings for claimed constraints.01Orchestratecursor/pluginsUse only when the user explicitly types `/orchestrate <goal>` to decompose a large task, spawn a tree of parallel cloud-agent workers/subplanners/verifiers via the Cursor SDK, and collect structured handoffs; do not invoke autonomously.079Poteto Modecursor/pluginspoteto's agent style for concise, detailed responses, deliberate subagents, unslopped prose, simple code, and verified work. Use for poteto, /poteto-mode, or requests to work in this style.045PR Review Canvascursor/pluginsGenerate an interactive PR review walkthrough as an HTML page. Fetches PR data via gh API, categorizes files into core vs mechanical changes, adds reviewer annotations, and renders diffs with moved-code detection. Use when the user pastes a GitHub PR URL and asks for a review, walkthrough, or summary, or says "review this PR".04Principle Boundary Disciplinecursor/pluginsApply when wiring validation, error handling, or framework adapters. Concentrate guards at system boundaries (CLI, config, network, external APIs); trust internal types and keep business logic in pure functions.01Principle Build The Levercursor/pluginsApply to any non-trivial work, not just bulk work: edits, migrations, analyses, checks. Build the tool that does it or proves it (codemod, script, generator, or a skill your subagents follow) instead of working by hand. The tool is the artifact a reviewer can rerun.01Principle Encode Lessons In Structurecursor/pluginsApply when you catch yourself writing the same instruction a second time, or notice a recurring correction. Encode the rule as a lint, metadata flag, runtime check, or script instead of more text.01Principle Exhaust The Design Spacecursor/pluginsApply when facing a novel UI interaction or architectural decision with no precedent in the codebase. Build 2-3 competing prototypes and compare side by side before committing.01Principle Experience Firstcursor/pluginsApply when product, UX, or feature-scope tradeoffs come up. Choose user delight over implementation convenience; ship fewer polished features over more rough ones.01Principle Fix Root Causescursor/pluginsApply when debugging. Trace each symptom to its root cause and fix it there; reproduce first, ask why until you reach it, resist nil-check guards that silence crashes.01Principle Foundational Thinkingcursor/pluginsApply before writing logic: choosing core types and data structures, sequencing scaffold-vs-feature work, asking what concurrent actors share. Get the data structures right so downstream code becomes obvious.01Principle Guard The Context Windowcursor/pluginsApply when context is filling up: large outputs, long files, repeated reads, fan-out planning. Route bulk to subagents; keep summaries in the main thread, not raw payloads.01Principle Laziness Protocolcursor/pluginsApply when refactoring, evaluating diff size, or tempted to add abstractions, layers, or signal threading. Bias toward deletion and the smallest change that solves the problem.01Principle Make Operations Idempotentcursor/pluginsApply when designing commands, lifecycle steps, or processing loops that run amid crashes, restarts, and retries. Converge to the same end state regardless of partial prior runs.01Principle Migrate Callers Then Delete Legacy Apiscursor/pluginsApply when introducing a new internal API while old callers still exist. Migrate callers and delete the old API in the same wave instead of preserving compatibility layers.01Principle Minimize Reader Loadcursor/pluginsApply when reviewing or shaping code that's hard to trace. Count layers between question and answer, and hidden state in the reader's head; collapse one-caller wrappers and shrink mutable scope.01Principle Model The Domaincursor/pluginsApply when writing stateful logic, or when code branches a lot or repeats a shape assumption across files. Encode the domain in a structure instead of scattered conditionals.01Principle Never Block On The Humancursor/pluginsApply when tempted to ask 'should I do X?' on reversible work. Proceed, present the result, let the human course-correct after the fact; reserve confirmation for irreversible actions.01
