Principle-based Claude Code plugin for the full development lifecycle — planning, execution, authoring, code review, root-cause analysis, continuous improvement, ideation, spec-driven development, documentation, and code refinement.
Synthesizes multiple evaluation results into an actionable improvement plan. Use after grading and comparing skills to generate prioritized recommendations.
Reviews code for quality, security, and best practices. Invoke when user asks for code review, PR review, or code quality feedback.
Compares two skill versions to identify what changed and why it matters. Use when a skill was revised and you want to understand the delta.
Scores skill outputs against teaching-focused rubrics. Use when evaluating whether a skill teaches judgment or just prescribes steps.
Expert prompt engineer for Claude Code. Use when creating, optimizing, or executing reusable prompts for task automation. Invoke when user asks to 'create a prompt', 'write a prompt', 'make a prompt executable', or 'run a prompt'.
Creates draft task files in .specs/tasks/draft/ from user intent. Use when user says 'capture this task', 'create a task', 'add to backlog', or 'log this as something to do'.
A3-format problem analysis with root cause investigation and action plan. Use when user says 'analyze this problem', 'root cause', 'why is this happening', or 'figure out what's wrong'.
Auto-selects improvement method (code exploration, workflow mapping, or waste identification) for a given target. Use when user says 'analyze this', 'look into this code', 'what's wrong here', or 'find the problem'.
Multi-agent code review for PRs and local changes. Use when user says 'review this PR', 'check my changes', 'review the code', or 'audit this pull request'.
Refactors complex code to reduce cognitive load. Use when user says 'simplify this', 'clean up this code', 'reduce complexity', or 'this is too nested'.

Version: 0.4.0
A principle-based Claude Code plugin for building skills, subagents, and project plans.
For when you keep pasting the same instructions into chat, or when CLAUDE.md has grown into a procedure. Each skill teaches you to build better extensions — not by giving you templates and checklists, but by giving you the principles behind them.
# Install from GitHub marketplace
/plugin marketplace add Git-Fg/taches-principled
/plugin install taches-principled
# Or manual install
cp -r skills/* commands/* agents/* ~/.claude/
# Create a new skill
/skill create-skills
# Plan a project phase
/skill create-plans
# Create an executable prompt
/skill create-prompts
# Run a prompt via sub-task
/skill execute-prompts
# Debug an issue
/debug <issue description>
# Create a handoff for the next session
/whats-next
# Simplify code
/simplify [file-pattern]
Note: Skills are invoked via /skill <name> or by description routing — they don't create individual slash commands. The command shortcuts above (/debug, /simplify, /whats-next) are the only flat slash commands. All other skills load on description match.
Skills load on demand and give Claude domain expertise without bloating every conversation.
