Productizer: Living Spec Plugin and Marketplace for Claude Code

Repositorygitayg/productizerTool

Productizer is a Claude Code plugin for requirements management and spec-driven development. Distributed via a repository-based marketplace, it provides a 'spec' skill that tracks living product specifications and stops workflows when contradictions to prior agreements arise.

Key points

  1. Distributes the 'spec' skill for Claude Code, enforcing a living product specification that halts execution when new intents conflict with agreed requirements.
  2. Functions as a marketplace allowing single user-scope installation across multiple repositories without copying skills into local .claude/skills/ directories.
  3. Employs explicit semantic versioning in plugin.json instead of SHA-based releases to prevent in-progress changes from auto-deploying across consumer repos.
  4. Follows strict validation rules verified via 'claude plugin validate --strict'.

Why it matters

AI-assisted coding often suffers from drift against earlier architectural decisions. A living specification skill prompts Claude Code to validate every modification against prior constraints before writing code, keeping large codebases consistent.

Analysis

The project targets software engineers and organisations using Claude Code who require structured requirements governance across repositories. Built on Claude Code's plugin manifests and shell scripts, it demonstrates clear distribution mechanics. In terms of public maturity, the repository is brand new with zero stars and forks, though its internal versioning (4.43.0) and manifest structures reflect deliberate, preexisting design choices.
