Propose Feature Concept Skill

Purpose

Create a feature concept document that pitches the feature idea and explains the problem it solves. This is the first step in the feature proposal process.

When to Use

• User wants to propose a new feature for crumbly, forester, or other forest crates
• Starting to document a feature idea
• Need to explain "why" and "what" before diving into requirements

Prerequisites

• User has described the feature idea

Procedure

0. Offer Idea Honing (Optional)

Ask the user:

Would you like to use an idea honing process to bring more clarity to the concept? This involves working through questions one at a time to explore ambiguities and design considerations.

If yes, use the idea-honing skill following the protocol in skills/README.md. Return to this skill after idea honing is complete.

1. Determine Feature Number

Find the next available feature number:

ls -1d ./docs/features/[0-9][0-9][0-9][0-9]-* 2>/dev/null | tail -1

If no features exist, start with 0001. Otherwise, increment the last number.

2. Create Feature Name

Work with the user to create a concise, descriptive name:

• Use lowercase with hyphens
• Keep it short (2-4 words)
• Make it descriptive

Example: semantic-search, registry-management, skill-validation

3. Check for Idea Honing Document

ls ./planning/NNNN-feature-name/idea-honing.md 2>/dev/null

If it exists, reference it when writing the concept. The Q&A provides valuable material for the narrative.

4. Create Feature Directory

mkdir -p ./docs/features/NNNN-feature-name

Replace NNNN with the four-digit number and feature-name with the agreed name.

5. Copy Concept Template

cp ./docs/features/0000-templates/concept.md ./docs/features/NNNN-feature-name/

6. Fill in Concept Document

Work with the user to complete concept.md as a narrative:

Frontmatter

• Set feature: to NNNN-feature-name
• Set status: to proposed
• Add optional tracking-issue: if applicable

Problem Section

• Paint a picture of the current situation
• Describe the pain this causes
• Explain why this matters

Solution Section

• Describe what users will experience
• Focus on "what" and "why" rather than "how"
• Keep it narrative, not a list

How It Works Section

• Tell the story of using the feature
• Walk through the workflow naturally
• Show real usage, not abstract steps

Benefits Section

• Explain the value provided
• Connect back to the problem
• Show what becomes possible

Technical Notes Section

• Brief constraints or considerations
• Keep it short - details go in design.md

7. Review for Narrative Flow

Ensure the document:

• Reads like a story, not a specification
• Avoids bullet points and numbered lists where possible
• Focuses on user experience and value
• Explains "why" before "what"

Validation

Verify the concept was created correctly:

# Check directory exists
ls -la ./docs/features/NNNN-feature-name/

# Verify concept file exists
ls ./docs/features/NNNN-feature-name/concept.md

# Check it has content
cat ./docs/features/NNNN-feature-name/concept.md

Common Issues

Too technical: If the concept reads like a design doc, refocus on the problem and user experience.

Too abstract: If the concept is vague, work with the user to add concrete examples of the pain point.

List-heavy: If there are many bullet points, rewrite as narrative prose.

Next Steps

After creating the concept:

1. Review and refine the narrative
2. Get feedback on whether the feature is valuable
3. Once concept is solid, move to requirements using propose-feature-requirements skill
