AgenticSkills — One-shot installer for oh-my-gods

Keywords: AgenticSkills · agenticskills · oh-my-gods · god-skills

Use this skill when the user wants to drop the entire oh-my-gods bundle (80+ curated agent skills) onto their machine without picking each one individually.

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:

1. Target platforms: claude, codex, gemini, opencode, or all (default).
2. LangChain bundle: install alongside (WITH_LANGCHAIN=true) or not.
3. 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.

Best practices

1. Review before piping curl | bash when the user has a security policy.
2. Pin a commit if the user wants reproducibility — replace main in the installer URL with a tag or commit SHA.
3. 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.
4. Re-run after upstream changes rather than diffing individual skills — the upstream installer handles the canonical sync.
