Comprehensive project planning and documentation generator for software projects. Creates structured requirements documents, system design documents, and task breakdown plans with implementation tracking. Use when starting a new project, defining specifications, creating technical designs, or breaking down complex systems into implementable tasks. Supports user story format, acceptance criteria, component design, API specifications, and hierarchical task decomposition with requirement…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Project Planner Skill This skill provides templates and guidance for generating comprehensive project planning documents that serve as blueprints for AI-assisted implementation. ## Quick Start When a user wants to start a new project, generate three core documents: 1. **Requirements Document** - User stories with acceptance criteria 2. **Design Document** - Technical architecture and component specifications 3. **Implementation Plan** - Hierarchical task breakdown with requirement tracing ## Why Explicit Architectural Planning Works Setting clear roles, responsibilities, and deliverables upfront dramatically improves project outcomes: ### Benefits of Upfront Definition 1. **Component Clarity** - Defining all system components first prevents scope creep and ensures complete coverage 2. **Data Flow Visibility** - Mapping data movement early reveals integration complexities and performance bottlenecks 3. **Integration Planning** - Identifying all touchpoints upfront prevents surprise dependencies during implementation 4. **Clear Boundaries** - Explicitly stating what's in/out of scope focuses effort and prevents feature drift …

How to install
mdr add 428alexander9/claude-skills-marketplace/project-planner@sha256:f28924ef91365ba9The line at the top of this page pins the label git:20251019.d25e143, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
