Portable agent skills by Greg Lichtenthal for people who want AI to strengthen human creativity, judgment, and agency.
This catalog is built around judgment infrastructure for human-led AI work: organize messy context, pressure-test the thinking, deliberate consequential decisions, and test ideas before trusting them.

The suite installer downloads the pinned stable release of all four skills into Codex's current user-skills directory:
git clone https://github.com/glichtenthal/agent-skills.git
cd agent-skills
bash install.sh --target codexUse --dry-run to preview the installation, --update to replace existing copies, or --skill the-quorum to install one skill. AI Project Steward is an optional applied skill, so install it explicitly with bash install.sh --skill ai-project-steward. Run bash install.sh --help for all options.
For ChatGPT or Claude, import each .skill release through the product's Skills settings. The shell installer is for Codex.
You do not need the full loop every time. Start with the part that matches what you have.
| If you have... | Use... | Output |
|---|---|---|
| Messy notes, transcripts, research, or context | The Briefing Room | A brief you can think with |
| A claim, plan, draft, or idea that needs honest critique | Ground Truth | Weak assumptions, missing evidence, and sharper next steps |
| A consequential decision with real trade-offs | The Quorum | Structured disagreement and a calibrated recommendation |
| An idea, claim, or decision that needs proof before commitment | Test Drive | The smallest credible test and the signal that would change your mind |
Turn messy context into a brief you can think with.

- Test Drive turns ideas, claims, and decisions into small evidence-seeking trials.
Ready to build? AI Project Steward carries the work into implementation.
Applied Judgment Systems carry human-led judgment into a specific domain or stage of work. AI Project Steward is the first, focused on moving from an idea or decision into implementation.
An active AI collaborator for apps, prototypes, automations, and integrations. It keeps consequential choices visible, preserves approval boundaries, records accepted decisions, and verifies the working result.
- Install: https://github.com/glichtenthal/ai-project-steward/releases/download/v2.0.0/ai-project-steward.skill
- Best for: human-led AI builds where data, cost, security, portability, deployment, or maintenance choices matter.
