Agent Skills Updater — Development skill for Claude Code

Agent Skills Pack & Updater

An opinionated, batteries-included collection of the Agent Skills I use, with one-command installation across Claude Code, Codex, DeepSeek Harness (DSH), Pi, Amp, Cursor, and compatible harnesses.

The pack fetches skills directly from their official upstream repositories and provides repeatable updates. On macOS it can also update everything daily with `launchd`, retained logs, and failure notifications.

Included Skills

Skill set	What gets installed
Cursor	thermo-nuclear-code-quality-review
LY Corporation	sim-use
OpenClaw	autoreview
Matt Pocock	Every non-deprecated skill in the upstream collection
Anthropic	The official, unmodified code-simplifier

See [Skill sources and distribution strategy](docs/skill-sources.md) for provenance, licenses, and the supply-chain model. The design note [What `dsh-find-simplifications` teaches this pack](docs/dsh-find-simplifications-review.md) records the evidence-first simplification rubric used here.

Quick start

Requirements: Bash, Git, curl, and Python 3. No API key or GitHub token is required for the default public sources.

git clone https://github.com/BoWuGit/agent-skills-updater.git
cd agent-skills-updater
./install.sh

That command:

1. installs the updater under ~/.local/libexec/agent-skills-updater;
2. exposes ~/.local/bin/update-all-skills;
3. fetches and installs the complete skill set;
4. detects installed agent harnesses and links skills into them;
5. on macOS, schedules a quiet daily update at 10:00 local time.

Reload or restart your agent harnesses after the first installation.

Useful installation options

# Install skills but do not add the macOS daily schedule
