December 2025: Speck Reviewer Plugin (Spec 018)

Intelligent PR Reviews with Spec Awareness

Released: December 2025

A new Claude Code plugin for structured pull request reviews with semantic clustering, Speck integration, and intelligent comment management.

Key Capabilities:

  • Cluster-based review: Automatically groups related files into semantic clusters for organized review
  • Speck-aware context: Loads associated feature specs to validate implementation alignment
  • Comment staging: Stage, refine, and batch-post comments to GitHub with approval actions
  • Session persistence: Resume interrupted reviews with full progress preservation

Review Commands:

  • /speck-reviewer:review [pr-number]: Start a PR review with cluster analysis
  • Natural navigation: “next”, “back”, “go to [cluster]”, “where was I?”
  • Comment refinement: “reword”, “skip”, “combine”, “post all then approve”
  • Self-review mode for reviewing your own PRs

Benefits:

  • Reduced cognitive load through semantic file grouping
  • Comments can reference spec requirements (e.g., “This implements FR-003”)
  • No context switching—review entirely within Claude Code
  • Works with or without Speck specs (graceful degradation)

Installation:

/plugin marketplace add https://raw.githubusercontent.com/nprbst/speck/main/.claude-plugin/marketplace.json
/plugin install speck-reviewer@speck-market
