Installation

• Tease: Install HTMA Measure alone or load it through Sam’s shared skill bundle.
• Lede: Every path below resolves to the same canonical skills/htma-measure directory.
• Why it matters: Standalone installation keeps context narrow; the bundle makes all of Sam’s published skills available together.
• Go deeper: Choose one tested path, verify the resulting files, and use the correct standalone or bundled invocation name.

Choose one installation path. They all expose the same canonical skills/htma-measure content.

The Skills CLI can install only HTMA Measure. The Codex and Claude marketplace bundle keeps the stable install ID htma-measure and loads every skill currently published in this repository. Claude Code uses the collection-level sam namespace after installation.

Open Skills CLI

This is the most portable path. The command is npx skills—plural.

List the skills found in the repository without installing:

npx skills add thatguysam/skills --list

Install only HTMA Measure into the current project:

npx skills add thatguysam/skills --skill htma-measure

Install non-interactively for Codex:

npx skills add thatguysam/skills \
  --skill htma-measure \
  --agent codex \
  --yes

Install globally instead of in one project:

npx skills add thatguysam/skills \
  --skill htma-measure \
  --agent codex \
  --global \
  --yes

A project-scoped Codex install lands at:

.agents/skills/htma-measure/

To disable the Skills CLI’s anonymous telemetry for an install:

DISABLE_TELEMETRY=1 npx skills add thatguysam/skills \
  --skill htma-measure \
  --agent codex \
  --yes

Codex plugin

Register the public marketplace, then install the plugin:

codex plugin marketplace add thatguysam/skills
codex plugin add htma-measure@thatguysam-skills

Verify that it is installed and enabled:

codex plugin list --json

The plugin reports its version and marketplace source. Release 0.2.1 installs without additional authentication because the repository is public.

Claude Code plugin

Add the marketplace and install the plugin:

claude plugin marketplace add thatguysam/skills
claude plugin install htma-measure@thatguysam-skills

Verify the installation:

claude plugin list --json

The marketplace uses a same-repository relative source. Claude clones the public marketplace over HTTPS and copies the plugin from that checkout, so installing it does not require a GitHub SSH key.

The bundle invokes this skill as /sam:htma-measure. A standalone Claude Code installation invokes it as /htma-measure.

Manual installation

Clone the repository:

git clone https://github.com/ThatGuySam/skills.git
cd skills

Copy the skill directory into the location your agent discovers:

mkdir -p .agents/skills
cp -R skills/htma-measure .agents/skills/htma-measure

Run that command from the cloned repository. To install from another directory, use absolute source and destination paths instead.

cp -R /path/to/skills/skills/htma-measure /path/to/project/.agents/skills/htma-measure

Verify the files

A complete installation contains:

htma-measure/
├── SKILL.md
├── agents/openai.yaml
├── assets/measurement-brief-template.md
└── references/
    ├── local-paid-quote-adjustment.md
    ├── method-map.md
    └── output-rubric.md

Next: run your first measurement.
