Feature Planning

VerifiedSafe

Generates a detailed implementation plan in specs/*.md for a new feature. It follows a structured template with description, user story, steps, and acceptance criteria, after researching existing code patterns and conventions.

Our review

This skill creates a structured plan for implementing a new feature by following a detailed template and analyzing the existing codebase.

Strengths

  • Step-by-step guide for planning complex features
  • Encourages reuse of existing patterns
  • Includes sections for testing and validation

Limitations

  • Requires a well-structured codebase to be effective
  • Can be overly rigid for very simple features
When to use it

Use this skill when you need to implement a non-trivial feature and want a clear plan before coding.

When not to use it

Do not use it for minor bug fixes or refactoring tasks that don't require a formal plan.

Security analysis

Safe
Quality score80/100

The skill only generates a planning document in markdown format; it does not execute any commands or require external tools. There is no risk of destructive actions.

Feature Planning

Create a new plan in specs/*.md to implement the Feature using the exact specified markdown Plan Format. Follow the Instructions to create the plan use the Relevant Files to focus on the right files.

Instructions

  • You're writing a plan to implement a net new feature that will add value to the application.
  • Create the plan in the specs/*.md file. Name it appropriately based on the Feature.
  • Use the Plan Format below to create the plan.
  • Research the codebase to understand existing patterns, architecture, and conventions before planning the feature.
  • IMPORTANT: Replace every <placeholder> in the Plan Format with the requested value. Add as much detail as needed to implement the feature successfully.
  • Use your reasoning model: THINK HARD about the feature requirements, design, and implementation approach.
  • Follow existing patterns and conventions in the codebase. Don't reinvent the wheel.
  • Design for extensibility and maintainability.
  • If you need a new library, use npm add and be sure to report it in the Notes section of the Plan Format.
  • Respect requested files in the Relevant Files section.
  • Start your research by reading the README.md file.

Relevant Files

Focus on the following files:

  • README.md - Contains the project overview and instructions.
  • convext_rules.txt - Contains Convex rules for backend.
  • src/** - Contains the NextJS application with app router.

Ignore all other files in the codebase.

Plan Format

# Feature: <feature name>

## Feature Description
<describe the feature in detail, including its purpose and value to users>

## User Story
As a <type of user>
I want to <action/goal>
So that <benefit/value>

## Problem Statement
<clearly define the specific problem or opportunity this feature addresses>

## Solution Statement
<describe the proposed solution approach and how it solves the problem>

## Relevant Files
Use these files to implement the feature:

<find and list the files that are relevant to the feature describe why they are relevant in bullet points. If there are new files that need to be created to implement the feature, list them in an h3 'New Files' section.>

## Implementation Plan
### Phase 1: Foundation
<describe the foundational work needed before implementing the main feature>

### Phase 2: Core Implementation
<describe the main implementation work for the feature>

### Phase 3: Integration
<describe how the feature will integrate with existing functionality>

## Step by Step Tasks
IMPORTANT: Execute every step in order, top to bottom.

<list step by step tasks as h3 headers plus bullet points. use as many h3 headers as needed to implement the feature. Order matters, start with the foundational shared changes required then move on to the specific implementation. Include creating tests throughout the implementation process. Your last step should be running the `Validation Commands` to validate the feature works correctly with zero regressions.>

## Testing Strategy
### Unit Tests
<describe unit tests needed for the feature>

### Integration Tests
<describe integration tests needed for the feature>

### Edge Cases
<list edge cases that need to be tested>

## Acceptance Criteria
<list specific, measurable criteria that must be met for the feature to be considered complete>

## Validation Commands
Execute every command to validate the feature works correctly with zero regressions.

<list commands you'll use to validate with 100% confidence the feature is implemented correctly with zero regressions. every command must execute without errors so be specific about what you want to run to validate the feature works as expected. Include commands to test the feature end-to-end.>

## Notes
<optionally list any additional notes, future considerations, or context that are relevant to the feature that will be helpful to the developer>
