Claude Code plugins by Leandro Zubrezki.

Plugins

spec-interview

A multi-round interview skill that refines a rough SPEC.md into a complete, implementation-ready specification, inspired from Thariq's tweet:

What it does:

1. Reads your SPEC.md file and explores the relevant codebase
2. Interviews you across multiple rounds, covering edge cases, data modeling, security, performance, UX, and tradeoffs
3. Writes a refined, unambiguous specification
4. Creates an ordered task list with dependencies for implementation
5. After implementation, runs verification, code review, and simplification passes

Usage:

1. Create a SPEC.md file in your project root with your rough idea or draft spec
2. Run /spec-interview:spec-interview

Or just describe what you want to build and Claude will invoke it automatically when it detects a SPEC.md in your project.

idea-storm-x4

A structured brainstorming skill that generates 50 high-quality ideas using 4 parallel agents that debate and converge across 3 rounds.

What it does:

1. Launches 4 parallel agents, each generating 50 ideas from a different angle (Growth, Monetization, Community/UX, Content/Data)
2. Runs 2 semifinal debate agents that filter 200 ideas down to 100
3. Runs a final debate agent that merges duplicates and selects the top 50
4. Presents the curated list for you to pick winners

Usage:

/idea-storm-x4:idea-storm-x4

session-stats

A diagnostic skill that analyzes your Claude Code session data to surface usage patterns and help debug context limit issues.

What it does:

1. Parses all session files from ~/.claude/projects/
2. Reports total tokens, messages, tool uses, and duration across all sessions
3. Ranks projects by token consumption
4. Flags heaviest sessions most likely to hit context limits
5. Lists longest sessions and recent activity
6. Suggests optimizations (when to /compact, use subagents, or break sessions)

Usage:

/session-stats:session-stats

cold-email

A cold email drafting skill based on Andy's "The art of cold-emailing a billionaire" framework, tested to achieve 100% pass rate on 8 quality assertions across 3 email types.

What it does:

1. Guides you through identifying the win-win trade before writing anything
2. Helps research the recipient to understand what they actually value
3. Drafts a concise email (under 150 words) applying 4 principles:
   • Competency — compressed proof of credibility in 1-2 sentences
   • Ask — specific request + clear value to the recipient
   • Transparency — honest about your self-interest and motivation
   • Extra effort — references something concrete you already created beyond the email
4. Reviews and cuts ruthlessly to keep it tight

Usage:

/cold-email:cold-email

Or just ask Claude to help you write a cold email — it will invoke the skill automatically.
