This skill is a thin, declarative wrapper around the official install.sh that ships with akillness/oh-my-gods. It pins the installer URL, exposes the canonical environment knobs, and documents how to target a subset of runtimes from a single command.

When to use this skill

The user says "install AgenticSkills", "bring in oh-my-gods", "add the god skills bundle", or any equivalent phrasing.
A new machine needs the full agent-skills catalog before any specific skill is touched.
An existing install needs to be refreshed (re-running is safe — the upstream installer backs up the previous install unless SKIP_BACKUP=true).
The user wants to add LangChain skills alongside oh-my-gods (WITH_LANGCHAIN=true).

Do not use when

The user only needs one specific skill from oh-my-gods → copy that single .god-skills/<name>/ directory instead, or use npx skills add with --skill <name>.
The user has not yet authorized network access (curl | bash) — fall back to git clone + manual review.

Instructions

Step 1 — Confirm scope with the user

Before running the installer, confirm:

Target platforms: claude, codex, gemini, opencode, or all (default).
LangChain bundle: install alongside (WITH_LANGCHAIN=true) or not.
Backup policy: keep existing ~/.agent-skills backup (default) or skip.

Step 2 — Run the installer

Pipe the upstream installer through bash with the chosen knobs:

# Default: install everything across every detected runtime, backup previous install
curl -fsSL https://raw.githubusercontent.com/akillness/oh-my-gods/main/install.sh | bash

# Claude Code only, with LangChain skills
PLATFORM=claude WITH_LANGCHAIN=true \
  curl -fsSL https://raw.githubusercontent.com/akillness/oh-my-gods/main/install.sh | bash

# Quiet re-install without backup (CI / scripted use)
INSTALL_MODE=silent SKIP_BACKUP=true \
  curl -fsSL https://raw.githubusercontent.com/akillness/oh-my-gods/main/install.sh | bash

For a security-conscious flow, download, review, then run:

curl -fsSLO https://raw.githubusercontent.com/akillness/oh-my-gods/main/install.sh
less install.sh           # human review
bash install.sh

Step 3 — Verify the install

ls ~/.agent-skills | head
ls ~/.claude/skills 2>/dev/null  | head
ls ~/.codex/skills 2>/dev/null   | head
ls ~/.gemini/skills 2>/dev/null  | head
ls ~/.opencode/skills 2>/dev/null | head

You should see directories such as agent-browser, agent-workflow, agentation, ai-research-skills, api-design, and the rest of the .god-skills/ catalog mirrored into each detected runtime.

Step 4 — Re-run or update

The installer is idempotent. To refresh:

curl -fsSL https://raw.githubusercontent.com/akillness/oh-my-gods/main/install.sh | bash

A backup of the previous ~/.agent-skills is written next to the directory unless SKIP_BACKUP=true is set.

Environment variables

Variable	Default	Purpose
`INSTALL_GLOBAL`	`true`	Install to canonical `~/.agent-skills`
`INSTALL_MODE`	`silent`	`silent` · `auto` · `interactive`
`SKIP_BACKUP`	`false`	Skip backup of an existing install
`WITH_LANGCHAIN`	`false`	Also install `langchain-ai/langchain-skills`
`PLATFORM`	`all`	`claude` · `gemini` · `codex` · `opencode` · `all`

Catalog snapshot

oh-my-gods currently ships 80+ skills under .god-skills/, including:

agent-browser, agentation, agent-configuration, agent-development-principles
agent-evaluation, agent-manager, agent-principles, agent-workflow
agents-cli, ai-research-skills, api-design, api-documentation
…plus the long-tail engineering, ops, and data skills

Best practices

Review before piping curl | bash when the user has a security policy.
Pin a commit if the user wants reproducibility — replace main in the installer URL with a tag or commit SHA.
Co-exist with jeo-skills: this bundle installs alongside the skills already shipped by akillness/jeo-skills; there are no destructive overlaps as the destination namespaces differ.
Re-run after upstream changes rather than diffing individual skills — the upstream installer handles the canonical sync.
