Agent skills for working with VillageSQL. Skills run in Claude Code, Gemini CLI, agy, Codex, Cursor, Amp, Kiro, OpenCode, and OpenClaw.

Skills

Skill	What it does
vsql-extension-builder	Builds a VillageSQL extension end-to-end through a 7-phase persona-driven workflow. Discovers the current VEF API from live SDK headers — no hardcoded API names.

More skills will be added here over time.

Installing

Quick install

curl -sSL https://villagesql.com/skills | bash

Detects which agents are installed and configures each one. Supports Claude Code, Gemini CLI, agy, Codex, Cursor, Amp, Kiro, OpenCode, and OpenClaw. Re-running updates in place.

Override locations with env vars:

VILLAGESQL_SKILLS_SRC=~/code/villagesql-skills \
CLAUDE_SKILLS_DIR=~/.claude/skills \
  curl -sSL https://villagesql.com/skills | bash

Manual install (recommended for contributors)

Claude Code

git clone https://github.com/villagesql/villagesql-skills.git ~/code/villagesql-skills
mkdir -p ~/.claude/skills
ln -s ~/code/villagesql-skills/skills/vsql-extension-builder ~/.claude/skills/vsql-extension-builder

Verify the skill is loaded by typing / in Claude Code — the skill name should appear in the slash command list.

Gemini CLI

git clone https://github.com/villagesql/villagesql-skills.git ~/code/villagesql-skills
mkdir -p ~/.gemini/extensions
ln -s ~/code/villagesql-skills ~/.gemini/extensions/villagesql

Gemini CLI reads gemini-extension.json and loads GEMINI.md as context.

agy

git clone https://github.com/villagesql/villagesql-skills.git ~/code/villagesql-skills
mkdir -p ~/.gemini/antigravity-cli/plugins
ln -s ~/code/villagesql-skills ~/.gemini/antigravity-cli/plugins/villagesql

agy reads plugin.json and discovers skills from the skills/ subdirectory.

OpenCode

git clone https://github.com/villagesql/villagesql-skills.git ~/code/villagesql-skills
mkdir -p ~/.config/opencode/skills
ln -s ~/code/villagesql-skills/skills/vsql-extension-builder ~/.config/opencode/skills/vsql-extension-builder

OpenClaw

git clone https://github.com/villagesql/villagesql-skills.git ~/code/villagesql-skills
mkdir -p ~/.openclaw/workspace/skills
ln -s ~/code/villagesql-skills/skills/vsql-extension-builder ~/.openclaw/workspace/skills/vsql-extension-builder

To update later (all agents share the same clone):

git -C ~/code/villagesql-skills pull

Skill layout

Each skill follows the standard Agent Skills directory layout:

skills/
└── <skill-name>/
    ├── SKILL.md           # entry point — frontmatter, workflow, gates
    └── references/        # detailed material loaded on demand
        └── *.md

SKILL.md is loaded eagerly when the skill triggers and stays thin and procedural. Detail-heavy material (standards, checklists, environment commands) lives in references/ and is read by the agent only when the relevant phase needs it.

Contributing

Issues and pull requests welcome. For substantive changes — new skills, workflow restructuring, new references — open an issue first to discuss the shape before writing the skill.

A few conventions:

• Keep SKILL.md thin. If a section exceeds a screen, ask whether it belongs in references/ instead.
• Reference files describe process and principles, not specific API names — names should be discovered from live sources during the workflow, not hardcoded in the skill.
• Match the voice of existing skills: terse, imperative, no marketing language.

Testing changes locally

The quick installer clones the repo to ~/.local/share/villagesql-skills/ and symlinks skills from there into your agent directories — not from your working clone. If you used the quick installer, your agent reads that managed copy, not your working branch.

To test local changes, re-point the Claude Code symlink directly to your clone:

rm ~/.claude/skills/vsql-extension-builder
ln -s ~/code/villagesql-skills/skills/vsql-extension-builder ~/.claude/skills/vsql-extension-builder

Branch switches are then live immediately. When you're done, re-running the quick installer restores the managed copy.

If you add a new file to references/, also update the install script in villagesql-website/src/skills so it gets included for users of the quick installer.
