Code With JV Agent Skills

Shared reusable agent skills for the Code With JV cohort.

These skills are designed to be readable, editable, and easy to install from a shared repo.

Code With JV plugin

The formal plugin namespace is codewithjv.

Initial plugin skills:

• retro - run a retrospective on a task or chat history to find mistakes, inefficiencies, root causes, and durable improvements.
• extract-scripts - review a skill and extract deterministic, mechanical steps into portable shell scripts.

Claude Code invocations:

/codewithjv:retro
/codewithjv:extract-scripts

Codex invocations:

@codewithjv retro
@codewithjv extract-scripts

Antigravity invocations:

/retro
/extract-scripts

Claude Code plugin

The Claude Code plugin lives at:

plugins/claude-codewithjv

Add this repo as a Claude Code marketplace:

/plugin marketplace add CodeWithJV/agent-skills
/plugin install codewithjv@codewithjv

Test locally:

claude --plugin-dir ./plugins/claude-codewithjv

Then invoke:

/codewithjv:retro
/codewithjv:extract-scripts

Validate before release:

claude plugin validate ./plugins/claude-codewithjv

Codex plugin

The Codex plugin lives at:

plugins/codex-codewithjv

It uses the codewithjv namespace and exposes the same two skills from this repo.

Add this repo as a Codex marketplace:

codex plugin marketplace add CodeWithJV/agent-skills

Then open the Codex plugin directory and install codewithjv from the Code With JV marketplace.

Validate before release:

python3 ~/.codex/skills/.system/plugin-creator/scripts/validate_plugin.py ./plugins/codex-codewithjv

Antigravity plugin

The Antigravity plugin lives at:

plugins/antigravity-codewithjv

It uses Antigravity's published plugin.json package layout and exposes the same two skills from this repo.

Install locally with Antigravity CLI:

agy plugin install ./plugins/antigravity-codewithjv

Then invoke the installed skills from the Antigravity prompt:

/retro
/extract-scripts

For workspace-level loading without the CLI installer, copy the contents of plugins/antigravity-codewithjv to:

.agents/plugins/codewithjv

For global Antigravity loading, copy the contents to:

~/.gemini/config/plugins/codewithjv

Validate before release:

agy plugin validate ./plugins/antigravity-codewithjv

Install

List available skills:

npx skills add codewithjv/agent-skills --list

Install a specific skill:

npx skills add codewithjv/agent-skills --skill call-external-ai

Examples:

npx skills add codewithjv/agent-skills --skill review-context-hub
npx skills add codewithjv/agent-skills --skill retro
npx skills add codewithjv/agent-skills --skill create-locked-down-skill
npx skills add codewithjv/agent-skills --skill extract-scripts

What these are for

• automation-hitlist Interactively walk through the five-step method (map, rank, sketch, evaluate, hitlist) to find your highest-value AI automations, then keep the result as a living document: an automation hitlist (build now) and a learning hitlist (learn next).
• call-external-ai Call Codex or Gemini for second opinions, reviews, and alternative perspectives.
• create-locked-down-skill Scaffold a new workflow directory with locked-down permissions. Creates a .claude/settings.local.json that restricts tools to only what's needed, plus a CLAUDE.md with workflow instructions. Great for sandboxed, restricted workspaces.
• review-context-hub Review a repo as a context hub: structure, recent changes, instructions, skills, remotes, and access.
• extract-scripts Review a skill and extract deterministic, mechanical steps into shell scripts. Makes skills more reliable by separating precision work (scripts) from judgment work (AI). Scripts are location-independent and portable.
• retro Run a retrospective on a task or chat history to find mistakes, inefficiencies, root causes, and durable improvements.
