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) |

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

| Skill | 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 <goal>."

Project structure

skills/                          ← skill source (the real content)
  collaborating-with-claude/     ← bridge script + SKILL.md + references
  collaborating-with-antigravity/ ← bridge script + SKILL.md + references (agy; succeeds the retired Gemini CLI)
  collaborating-with-codex/      ← bridge script + SKILL.md + references + prompt recipes
  collaborating-with-grok/       ← bridge script + SKILL.md + references (Grok CLI; live web/X search)
  issue-driven-workflow/              ← plan/CSV workflow + templates + scripts
docs/setup/                      ← install runbooks per harness
AGENTS.md                        ← project-specific rules
AGENTS.issues.template.md        ← issue-driven workflow (apply on top of AGENTS.md)

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.
