redongreenCursor ruleredongreen/uSpec/.cursor/rules/mintlify.mdc
technical writing rule You are an AI writing assistant specialized in creating exceptional technical documentation using Mintlify components and following industry-leading technical writing practices. ## Core writing principles ### Language
danielvm-gitCursor ruledanielvm-git/bigpowers/.cursor/rules/assess-impact.mdc
Analyze the blast radius of a proposed change before any code is written. Maps dependents, affected stories, and test coverage. Produces specs/IMPACT_LATEST.md. Use before plan-work on any non-trivial change, when touching a shared module, or when the user asks \"what does this break?\".
danielvm-gitCursor ruledanielvm-git/bigpowers/.cursor/rules/audit-code.mdc
Self-review checklist for the coding agent to run before dispatching a reviewer. Checks CONVENTIONS.md compliance, Boy Scout Rule, test coverage, types, and SOLID. Produces a pass/fail checklist. Use before request-review, before committing, or when user asks for a code quality check.
danielvm-gitCursor ruledanielvm-git/bigpowers/.cursor/rules/audit-plan.mdc
Evaluate an incoming project plan against bigpowers principles and conventions, surface gaps, and produce a READY/NOT READY verdict before engagement begins. Use when a new project arrives, when adapting a foreign plan, or before running seed-conventions on an unfamiliar codebase.
danielvm-gitCursor ruledanielvm-git/bigpowers/.cursor/rules/craft-skill.mdc
Create new bigpowers skills with proper structure, progressive disclosure, and bundled resources. Use when user wants to create, write, or build a new skill for the bigpowers lifecycle.
danielvm-gitCursor ruledanielvm-git/bigpowers/.cursor/rules/deepen-architecture.mdc
Find deepening opportunities in a codebase, informed by the domain language in specs/tech-architecture/tech-stack.md and the decisions in specs/adr/. Use when the user wants to improve architecture, find refactoring opportunities, consolidate tightly-coupled modules, or make a codebase more testable and AI-navigable.
danielvm-gitCursor ruledanielvm-git/bigpowers/.cursor/rules/develop-tdd.mdc
Test-driven development with red-green-refactor loop using vertical slices. Use for features (epic tasks) or bugs (specs/bugs/BUG-*.md).
danielvm-gitCursor ruledanielvm-git/bigpowers/.cursor/rules/extract-design.mdc
Extract a Google DESIGN.md file from an HTML prototype (claude.ai/design or any styled page) using Puppeteer, producing machine-readable tokens and AI-generated prose. Use when the user has an HTML prototype and wants a DESIGN.md to anchor their project's visual identity, or when seed-conventions has just scaffolded a new project.
danielvm-gitCursor ruledanielvm-git/bigpowers/.cursor/rules/grill-me.mdc
Interactive assumption-surfacing Q&A that stress-tests a plan through relentless questioning until every decision is resolved. Use when user wants to challenge a plan, validate decisions from conversation/context, or mentions \"grill me\". For doc-grounded variant, use grill-with-docs.
Instruction files for Cursor's agent, kept in .cursor/rules/ as .mdc files.
A rule can apply only to files matching a pattern, or only when the agent asks for it. AGENTS.md always applies.
Copy the .mdc file into your project's .cursor/rules/ directory and adjust its globs.
Open a rule to see its discussion. Reports from people and their agents are coming.
