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:

bash

/feature-review --inventory

2. Score and Classify#

Evaluate features against the prioritization framework:

bash

/feature-review

3. Generate Suggestions#

Review gaps and suggest new features:

bash

/feature-review --suggest

4. Research-Enriched Scoring#

Use tome plugin to adjust scores with external evidence:

bash

/feature-review --research

5. Upload to GitHub#

Create issues for accepted suggestions:

bash

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

Workflow#

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

Identify features by analyzing:

1. Code artifacts: Entry points, public APIs, and configuration surfaces.
2. Documentation: README lists, CHANGELOG entries, and user docs.
3. 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

TypeDefinitionExamplesProactiveAnticipates user needs.Suggestions, prefetching.ReactiveResponds to explicit input.Form handling, click actions.

Axis 2: Static vs Dynamic

TypeUpdate PatternStorage ModelStaticIncremental, versioned.File-based, cached.DynamicContinuous, streaming.Database, real-time.

See classification-system.md for details.

Phase 3: Scoring ( feature-review:scored)#

Apply hybrid RICE+WSJF scoring:

text

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. See multi-metric-evaluation-methodology.md when one model is not enough: it covers how to combine RICE, WSJF, and Kano, where each model fits, and how to reconcile conflicting signals.

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

Evaluate each feature across quality dimensions:

DimensionQuestionScaleQualityDoes it deliver correct results?1-5LatencyDoes it meet timing requirements?1-5Token UsageIs it context-efficient?1-5Resource UsageIs CPU/memory reasonable?1-5RedundancyDoes it handle failures gracefully?1-5ReadabilityCan others understand it?1-5ScalabilityWill it handle 10x load?1-5IntegrationDoes it play well with others?1-5API SurfaceIs it backward compatible?1-5

See tradeoff-dimensions.md for criteria.

Phase 4.5: Research Enrichment ( feature-review:research-enriched)#

Triggered by: --research flag. Requires tome plugin.

Use tome's multi-source research to adjust scoring factors with external evidence. This phase runs between tradeoff analysis and gap analysis.

1. Dispatch research: For each feature, construct research topics and dispatch tome channels (code-search, discourse, papers, triz) in parallel.
2. Synthesize findings: Merge results across channels using tome:synthesize.
3. Calculate deltas: Map findings to scoring factor adjustments using channel-to-factor mapping.
4. Apply deltas: Adjust initial scores by research deltas, clamp to Fibonacci scale, respect max_delta.
5. Present evidence: Show adjustment table with evidence sources and rationale.

See research-enrichment.md for the full enrichment protocol, delta calculation, and graceful degradation behavior.

Graceful degradation: If tome is not installed, prints a warning and proceeds with initial scores unchanged.

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

1. Identify gaps: Missing Kano basics.
2. Surface opportunities: High-value, low-effort features.
3. Flag technical debt: Features with declining scores.
4. Recommend actions: Build, improve, deprecate, or maintain.

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

1. Generate issue title and body from suggestions.
2. Apply labels (feature, enhancement, priority/*).
3. Link to related issues.
4. Confirm with user before creation.

Deferred capture for high-scoring suggestions: After the user confirms which suggestions to act on, any high-scoring suggestion (score > 2.5) that is not acted on should be preserved as a deferred item. Run once per skipped high-scoring suggestion:

bash

python3 scripts/deferred_capture.py \
  --title "<suggestion title>" \
  --source feature-review \
  --context "RICE score: <score>. <description>"

This runs automatically without prompting the user. Suggestions with scores of 2.5 or below do not need to be captured.

Configuration#

Feature-review uses opinionated defaults but allows customization.

Configuration File#

Create .feature-review.yaml in project root:

yaml

# .feature-review.yaml
version: 1.9.3

# 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:

1. Minimum dimensions: Evaluate at least 5 tradeoff dimensions.
2. Confidence requirement: Review scores below 50% confidence.
3. Breaking change warning: Require acknowledgment for API surface changes.
4. Backlog limit: Limit suggestion queue to 25 items.
