Implements Manus-style file-based planning to organize and track progress on complex tasks. Creates task_plan.md, findings.md, and progress.md. Use when asked to plan out, break down, or organize a multi-step project, research task, or any work requiring >5 tool calls. Supports automatic session recovery after /clear.

Use when asked to "PMF survey", "measure product-market fit", "40% rule", "Sean Ellis test", "Rahul Vohra method", or "how disappointed would you be". Helps quantify product-market fit and systematically improve it. The PMF Survey framework (created by Sean Ellis, popularized by Rahul Vohra at Superhuman) measures how disappointed users would be without your product and turns that data into a roadmap.

Apply Ponytail's reuse-first ladder when the user invokes /ponytail, asks for the simplest implementation, or wants to avoid over-engineering and new dependencies in a coding task. Preserve all requested behavior and required checks. Not a default for every coding task, a prose-compression mode, or a replacement for the repository's debugging, testing, or refactoring workflow.

Use when asked to "position my product", "positioning canvas", "differentiate from competitors", "figure out our category", "repositioning", or "why customers should pick us". Helps define competitive alternatives, differentiated value, target customers, and market category. April Dunford's positioning framework from "Obviously Awesome" makes your product's value obvious to the right customers.

Generate comprehensive product requirements documents. Use when starting a new feature or product initiative and need structured documentation.

Use when asked about "product-led growth", "PLG strategy", "self-serve growth", "freemium model", "free trial design", "product-led sales", "PQL", or "bottoms-up growth". Helps design and optimize product-led growth motions where the product drives acquisition, activation, and monetization. Based on frameworks from Elena Verna and Hila Qu.

Use when asked to "product-led SEO", "programmatic SEO", "build programmatic pages", "organic acquisition for product", "decide if SEO is worth it", or "optimize for AI search". Helps evaluate whether SEO fits your business model and how to approach it as a product, not just marketing. The Product-Led SEO framework (created by Eli Schwartz) treats SEO as building products for search users.

Maintain or create PROJECT_STATUS.md files at the repository root with the canonical structure (Executive Summary, Completed Components, In Progress, Next Steps, Known Issues, Notes). Use when starting or finishing work on a project, when the user asks to update or create PROJECT_STATUS.md, when a session involves significant changes that should be reflected in the project status file, or when reviewing project state before committing.

Design and run promptfoo evaluations for LLM behavior regressions or comparisons across prompts, agent rules, and models. Use for repeatable behavioral cases with explicit assertions, not ordinary unit tests or static configuration checks.

Use when asked to "radical candor", "give feedback that cares", "have a difficult conversation", "challenge directly", "manage performance issues", or "give praise that lands". Helps deliver direct feedback while showing you care. The Radical Candor framework (created by Kim Scott) teaches how to challenge directly while caring personally.

Refactoring process. Invoke immediately when user or document mentions refactoring, or proactively when code gets too complex or messy.

Iterative code refactoring through progressive lenses via a worker-reviewer agent team.

Iterative refinement through multiple passes. Use when the user asks to 'meditate on', 'distill', 'refine', or 'iterate on' something, or proactively when a problem benefits from multiple passes rather than a single attempt.

Rename the current chat to match its focus. Use only when the user invokes /rename-chat. Optional text after the command steers the title.

Review code changes with the Bugbot or Security Review subagent.

Guide users building apps, scripts, CI pipelines, or automations on top of the Cursor SDK - TypeScript (`@cursor/sdk`) or Python (`cursor-sdk` / `cursor_sdk`). Use when the user mentions integrating, installing, or writing code against the Cursor SDK; says `Agent.create`, `Agent.prompt`, `Agent.resume`, `agent.send`, `run.stream`, `run.messages`, `CursorAgentError`, `@cursor/sdk`, `cursor-sdk`, or `cursor_sdk`; asks to run Cursor agents programmatically from a script, CI/CD pipeline, GitHub Action, backend service, or other code outside the Cursor IDE; wants to pick between local and cloud runtime, configure MCP servers for an SDK agent, or handle streaming, cancellation, or errors; or is wiring Cursor into an automation, bot, or REST `/v1/agents` migration. Use eagerly rather than answering from memory; the SDK surface evolves and this skill is the source of truth for the external packages.

Sets up an `## Agent skills` block in AGENTS.md/CLAUDE.md and `docs/agents/` so the engineering skills know this repo's issue tracker (GitHub or local markdown), triage label vocabulary, and domain doc layout. Run before first use of `to-issues`, `to-prd`, `triage`, `diagnose`, `tdd`, `improve-codebase-architecture`, or `zoom-out` — or if those skills appear to be missing context about the issue tracker, triage labels, or domain docs.

Use when asked to "7 Powers", "build a competitive moat", "analyze defensibility", "find sustainable advantage", "economic moats", or "Hamilton Helmer framework". Helps identify durable competitive advantages. The 7 Powers framework (created by Hamilton Helmer) reveals the economic structures that protect business value from competition.
