A collection of plugins, skills, and CLI tools for AI-assisted development with Claude Code. Designed to be installed from a marketplace or used as standalone components.

Problem

Claude Code is powerful out of the box, but recurring development patterns — writing specs before code, extracting lessons from session logs, managing skills across projects — require custom tooling. Without reusable plugins, each project reinvents the same workflows.

Approach

Bryce Labs Toolkit packages common AI-paired development patterns as installable Claude Code plugins. Each plugin is self-contained with its own skills, commands, and configuration, following the marketplace plugin format for easy distribution.

What’s Included

• Spec-driven development plugin — Enforces a write-the-spec-first workflow where Claude Code generates implementation specs before writing any code, with validation gates between planning and execution
• Session history story miner — Extracts narrative arcs from Claude Code session logs, identifying what was attempted, what worked, what failed, and what was learned across development sessions
• Lessons extractor — Parses session transcripts to surface reusable insights, anti-patterns, and workflow improvements that feed back into CLAUDE.md project files
• Cross-platform skill management — Tooling for creating, testing, and distributing Claude Code skills across projects and teams

What This Demonstrates

Claude Code plugin architecture and marketplace integration, meta-tooling for AI-paired development (tools that improve the tool-using process), and systematic approaches to capturing and reusing development knowledge.
