How do I install agent-designer?

Run these in Claude Code: npx -y skills add appautomaton/agent-designer. Then prompt normally.

Does agent-designer auto-invoke its skills?

Not yet. It is indexed on Flowy as a plain plugin. Request auto-invocation on its page and Flowy will route its skills for you as you prompt.

Is agent-designer free?

Yes. Flowy is free and open source, with nothing gated. You can read every skill in full before you install.

Agent Designer

A catalog of installable skills for AI coding agents: Claude Code, Codex, Antigravity, and Grok.

Structured, reusable skills that give your agents clear workflows, safe defaults, and multi-turn collaboration capabilities. Install the ones you want into the harness you already use, and your agents work methodically rather than freestyle.

What's inside

Collaboration skills — let your agents delegate to each other via bridge scripts with session continuity:

Skill	Purpose
`collaborating-with-claude`	Delegate to Claude Code CLI (review, diff, consultation)
`collaborating-with-antigravity`	Delegate to Antigravity CLI `agy` (review, web search, image analysis)
`collaborating-with-codex`	Delegate to Codex CLI (implementation, diagnosis, review, image generation)
`collaborating-with-grok`	Delegate to Grok CLI (review, diagnosis, live web/X search; coding model e.g. `grok-4.5`)

Skill

Purpose

collaborating-with-claude

Delegate to Claude Code CLI (review, diff, consultation)

collaborating-with-antigravity

Delegate to Antigravity CLI agy (review, web search, image analysis)

collaborating-with-codex

Delegate to Codex CLI (implementation, diagnosis, review, image generation)

collaborating-with-grok

Delegate to Grok CLI (review, diagnosis, live web/X search; coding model e.g. grok-4.5)

Issue-driven development — structure work into plans and trackable Issue CSVs:

Skill	Purpose
`issue-driven-workflow`	Plan → Issue CSV → autonomous execution with status tracking

Purpose

issue-driven-workflow

Plan → Issue CSV → autonomous execution with status tracking

Getting started

[!TIP]

Pick the skills you want from skills/.
Follow the runbook for your harness in docs/setup/: install, approve, verify.
- To add the issue-driven workflow to a project: ask your agent to "apply AGENTS.issues.template.md on top of AGENTS.md".
Start working. Ask your agent to create a plan, generate an Issue CSV, or collaborate with another agent.
- Example: "Create a plan and Issue CSV for ."

How it works

Each skill follows progressive disclosure:

Level 1 (metadata) — name + description in YAML frontmatter. Always loaded. Used for discovery.

Level 2 (instructions) — the SKILL.md body. Loaded when the skill is invoked. Contains workflow, safety, quick start.

Level 3 (resources) — scripts/, references/, assets/. Loaded on demand. Contains deep docs, templates, helper scripts.

Notes

This repo is workflow-first — most changes are text, not code.

Bridge scripts wrap CLI tools and return structured JSON with session continuity.

Approval rules for the bridge scripts are documented per harness in docs/setup/, in wildcard forms that work at any install location. See the "Host-side approval" section in each skill.

Skills are portable across Codex and Claude Code with minimal adaptation.

If invoking bridge scripts directly, prefer python3.
