Install

Copy this and paste it into Claude Code, Cursor, or any AI assistant:

I want to install the "psi" skill in my project.

Please run this command in my terminal:
# Install skill into the correct directory (2 files)
mkdir -p .claude/skills/psi && curl --retry 3 --retry-delay 2 --retry-all-errors -o .claude/skills/psi/SKILL.md "https://raw.githubusercontent.com/majiayu000/claude-skill-registry/main/skills/data/psi/SKILL.md" && curl --retry 3 --retry-delay 2 --retry-all-errors -o .claude/skills/psi/metadata.json "https://raw.githubusercontent.com/majiayu000/claude-skill-registry/main/skills/data/psi/metadata.json"

Then restart Claude Code (or reload the window in Cursor) so the skill is picked up.

Description

Plan-spec-implement workflow for structured development. Only use when explicitly directed by user or when mentioned in project AGENTS.md file. Generates ephemeral plans in ~/.dot-agent/, applies specs to project docs, then implements test-first.

PSI - Plan Spec Implement

Structured workflow for planning, specifying, and implementing changes with documentation-first approach.

When to Use

Only use when: • Explicitly directed by the user • Mentioned in project AGENTS.md file Do not use automatically - this is an opt-in workflow, not a default.

Core Workflow

Plan → Spec → Implement Phases are independent - you can start with any phase, but all must ensure documentation stays up-to-date.

Key Principles

• Ephemeral planning - Plans stored in ~/.dot-agent/ (not committed) • Documentation-first - Specs applied to project docs/READMEs/AGENTS.md • Test-first implementation - Tests for docs/user journeys before code • Design/review embedded - Design and review integrated into Plan/Spec phases • Phase independence - Each phase can work standalone, all update docs
