Sam's Skills

Sam's Skills contains reusable workflows for Codex, Claude Code, and other agents that support the Agent Skills format. Install a single skill or the collection bundle. Each skill keeps its instructions in SKILL.md and loads supporting references when needed.

Skills

Skill	Use it for	Guide
Phone Size	Condense tasks, decisions, research, and updates into a phone-screen brief with supporting detail.	phone-size
Sam's Tree	Organize notes and other material into familiar, scannable trees.	sams-tree
Sam's Status	Show project work as a status tree with sources, progress, and missing information.	sams-status
Sam's Env	Draft environment examples with setup links, value guidance, annotation checks, and consistent spacing.	sams-env
Andrej Explain	Explain complex material and agent work through useful text, diagrams, HTML, or video.	andrej-explain
Migrate Custom GPTs	Back up GPT workflows privately and convert them to portable skills while tracking migration gaps.	migrate-cgpt
Sales Research	Research sales decisions and draft buyer communication using relevant practitioner sources.	sales-research
Sam's Gen Writing	Draft, review, or plan AI-assisted pages using Google's published Search guidance.	sams-gen-writing
Sam's Skill Creator	Create and improve agent skills with locked authoring sources and behavioral validation.	sams-skill-creator
Sam UX Audit	Audit websites and repository UX with locked review dependencies and evidence-backed findings.	sam-ux-audit
Zach Prompting	Improve prompts and agent instructions while preserving their intent and safeguards.	zach-prompting
HTMA Measure	Estimate uncertain quantities with ranges, sources, and decision recommendations.	htma-measure
Agent Verify	Verify new work and compare before/after improvements with fresh subagents and independent QA.	agent-verify

Install a listed skill with npx skills add ThatGuySam/skills --skill <id>. Each linked guide includes usage examples and verification limits. Sam's Skill Creator and Sam UX Audit restore their locked dependencies on first use.

Try a skill

These examples show a few ways to start after installation:

Use $sams-skill-creator to turn this workflow into a focused, tested skill.
Use $sams-env to draft this project's .env.example.
Use $htma-measure to create a planning allowance for this project before quotes arrive.

For skill authoring, review the validation record. First use requires Node.js, npm, and Git to restore the private dependency set. Ordinary runs keep that set locked. Request a refresh explicitly.

For measurement, the HTMA Measure README explains the workflow, and its evaluation suite records verification. For environment templates, the synthetic test contract documents the checker limits.

Other installation paths

Clone the repository and copy the required directory from skills/ into your agent's skills directory:

git clone https://github.com/thatguysam/skills.git

The repository also ships a marketplace bundle for Codex and Claude Code. The bundle loads every published skill; use the Skills CLI when you want only one. Its stable install ID remains htma-measure, while Claude Code uses the collection-level sam command namespace.

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

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

Claude Code namespaces bundled skills with sam, for example /sam:zach-prompting and /sam:htma-measure. Standalone installations keep their unbundled names. Codex skill selectors remain $zach-prompting and $htma-measure.
