Feature Review

Review implemented features and suggest new ones using evidence-based prioritization. Create GitHub issues for accepted suggestions.

Philosophy

Feature decisions rely on data. Every feature involves tradeoffs that require evaluation. This skill uses hybrid RICE+WSJF scoring with Kano classification to prioritize work and generates actionable GitHub issues for accepted suggestions.

When To Use

• Roadmap reviews (sprint planning, quarterly reviews).

• Retrospective evaluations.

• Planning new development cycles.

When NOT To Use

• Emergency bug fixes.

• Simple documentation updates.

• Active implementation (use scope-guard ).

Quick Start

1. Inventory Current Features

Discover and categorize existing features:

/feature-review --inventory

2. Score and Classify

Evaluate features against the prioritization framework:

/feature-review

3. Generate Suggestions

Review gaps and suggest new features:

/feature-review --suggest

4. Upload to GitHub

Create issues for accepted suggestions:

/feature-review --suggest --create-issues

Workflow

Phase 1: Feature Discovery (feature-review:inventory-complete )

Identify features by analyzing:

• Code artifacts: Entry points, public APIs, and configuration surfaces.

• Documentation: README lists, CHANGELOG entries, and user docs.

• Git history: Recent feature commits and branches.

Output: Feature inventory table.

Phase 2: Classification (feature-review:classified )

Classify each feature along two axes:

Axis 1: Proactive vs Reactive

Type Definition Examples

Proactive Anticipates user needs. Suggestions, prefetching.

Reactive Responds to explicit input. Form handling, click actions.

Axis 2: Static vs Dynamic

Type Update Pattern Storage Model

Static Incremental, versioned. File-based, cached.

Dynamic Continuous, streaming. Database, real-time.

See classification-system.md for details.

Phase 3: Scoring (feature-review:scored )

Apply hybrid RICE+WSJF scoring:

Feature Score = Value Score / Cost Score

Value Score = (Reach + Impact + Business Value + Time Criticality) / 4 Cost Score = (Effort + Risk + Complexity) / 3

Adjusted Score = Feature Score * Confidence

Scoring Scale: Fibonacci (1, 2, 3, 5, 8, 13).

Thresholds:

• 2.5: High priority.

• 1.5 - 2.5: Medium priority.

• < 1.5: Low priority.

See scoring-framework.md for the framework.

Phase 4: Tradeoff Analysis (feature-review:tradeoffs-analyzed )

Evaluate each feature across quality dimensions:

Dimension Question Scale

Quality Does it deliver correct results? 1-5

Latency Does it meet timing requirements? 1-5

Token Usage Is it context-efficient? 1-5

Resource Usage Is CPU/memory reasonable? 1-5

Redundancy Does it handle failures gracefully? 1-5

Readability Can others understand it? 1-5

Scalability Will it handle 10x load? 1-5

Integration Does it play well with others? 1-5

API Surface Is it backward compatible? 1-5

See tradeoff-dimensions.md for criteria.

Phase 5: Gap Analysis & Suggestions (feature-review:suggestions-generated )

• Identify gaps: Missing Kano basics.

• Surface opportunities: High-value, low-effort features.

• Flag technical debt: Features with declining scores.

• Recommend actions: Build, improve, deprecate, or maintain.

Phase 6: GitHub Integration (feature-review:issues-created )

• Generate issue title and body from suggestions.

• Apply labels (feature, enhancement, priority/*).

• Link to related issues.

• Confirm with user before creation.

Configuration

Feature-review uses opinionated defaults but allows customization.

Configuration File

Create .feature-review.yaml in project root:

.feature-review.yaml

version: 1

Scoring weights (must sum to 1.0)

weights: value: reach: 0.25 impact: 0.30 business_value: 0.25 time_criticality: 0.20 cost: effort: 0.40 risk: 0.30 complexity: 0.30

Score thresholds

thresholds: high_priority: 2.5 medium_priority: 1.5

Tradeoff dimension weights (0.0 to disable)

tradeoffs: quality: 1.0 latency: 1.0 token_usage: 1.0 resource_usage: 0.8 redundancy: 0.5 readability: 1.0 scalability: 0.8 integration: 1.0 api_surface: 1.0

See configuration.md for options.

Guardrails

These rules apply to all configurations:

• Minimum dimensions: Evaluate at least 5 tradeoff dimensions.

• Confidence requirement: Review scores below 50% confidence.

• Breaking change warning: Require acknowledgment for API surface changes.

• Backlog limit: Limit suggestion queue to 25 items.
