Simple Skills

Reusable AI agent skills for idea validation, advanced brainstorming, closure retrospectives, code review delegation, formal change orchestration, and startup research.

This repository contains installable skills for the skills.sh ecosystem and for coding agents such as Codex, Claude Code, Cursor, Cline, OpenCode, and Goose. The current skills focus on five practical jobs:

• validating whether a product, startup, feature, or workflow idea is worth pursuing
• expanding an idea into broader, less conservative, more imaginative directions
• reflecting at task closure to decide whether reusable guidance should be codified
• deciding how to split code review across focused subagents
• orchestrating formal changes with OpenSpec artifacts, approval gates, and superpower discipline layers

Install from GitHub with npx skills add fightZy/simple-skills.

Why This Repo Exists

Many agent workflows fail for recurring reasons:

• teams build ideas before checking whether the market is too crowded or the positioning is too weak
• teams brainstorm but still collapse too quickly into safe or conventional options
• teams finish work without converting repeated friction into reusable guidance
• teams lack a unified workflow for formal changes, letting multiple planning systems compete and create confusion

This repo packages these workflows as reusable agent skills so they can be installed, shared, and reused across projects.

Skills

Idea Credibility Analyst

Evaluate whether an idea is worth pursuing before building.

Use it when you want a sharper answer than brainstorming alone, especially for differentiation, alternatives, market crowdedness, or a continue / pivot / stop call.

Docs: ICA-EN, ICA-ZH, ICA-SKILL

Advanced Brainstorming

Expand a proposal into broader, less conservative, more imaginative directions.

Use it when the user wants higher-order ideation instead of the safest recommendation, a shallow idea list, or an early MVP plan.

Docs: AB-EN, AB-ZH, AB-SKILL

Closure Retrospective

Review a task at wrap-up and decide whether any reusable lesson is worth codifying.

Use it when a non-trivial task is reaching closure and the work may justify a suggestion for an existing skill, a new skill, or AGENTS.md / CLAUDE.md.

Docs: CR-EN, CR-ZH, CR-SKILL

Dispatching Code Review Subagents

Decide whether code review should use one reviewer, multiple themed reviewers, or layered review.

Use it before delegating code review to subagents, especially when a change spans independent risk areas or could benefit from focused review lenses.

Docs: DCR-EN, DCR-ZH, DCR-SKILL

OpenSpec Superpower Orchestration

Orchestrate formal changes using OpenSpec artifacts plus superpower skill discipline layers.

Use it when work requires formal specs (proposal.md, design.md, spec.md, tasks.md), approval gates, and coordinated implementation without creating parallel planning systems.

Docs: OSO-EN, OSO-ZH, OSO-SKILL

Repository-level tests and other development-only assets live outside .agents/skills/. Installable skill directories contain only the runtime files that agents need to read or execute.

These commands work with the skills CLI and are intended for skill-compatible agents and editors.

Usage

After installation, each skill runs according to its own SKILL.md. Use the doc links above to understand scope, capabilities, and scenarios before installing or invoking a skill.

Repository Documentation

Keep durable project knowledge in its authoritative artifact instead of maintaining a parallel memory hierarchy:

• requirements and behavior in project specs
• architecture and technical rationale in docs/ or ADRs
• repository-wide agent and engineering rules in AGENTS.md or CLAUDE.md
• active work and follow-ups in the project issue tracker or task artifacts
