- kobayashi-special handles short lengths; permanent-pedometer handles long distances; moon-trips takes over at astronomical scale. They cross-reference each other.
- banana-for-scale handles everyday weights; blue-whale-bench handles heavyweight masses. They hand off to each other.
- sail-away anchors ordinary dates and spans; geologic-anchor takes over at deep-time scale.
- eiffel-tower-units (tall heights), library-of-congress (data), and olympic-pool (volume) round out the unofficial-unit family.
- The bovine cluster all comes from the same barn: the-four-stomachs, sacred-cow-slayer, cash-cow-calculator, bull-detector, herd-immunity, rumination-station, cattle-prod, pasture-rotation, methane-ledger, holy-cow-alarm, branding-iron, and the-whole-cow. flavor-of-the-day scoops the dairy they produce. 🐄🍦
- farmer-wisdom does not apply when token-saver-9000 is invoked — you cannot reckon in one word.
All skills apply only to conversational replies, not to work artifacts (code, docs, emails, etc.).
These are markdown instructions that tell the AI how to behave in specific situations. They work exactly as designed (which is to say they are not designed to help you get work done).
Install shills with a single command:
npx skills add aubcake/shillsThis works across Cursor, Claude Code, Codex, Gemini CLI, Google Antigravity, OpenClaw, Pi, and any other agent that supports the open Agent Skills standard.
If you use the GitHub CLI (v2.90.0+), you can install skills with gh skill:
# Browse and install interactively
gh skill install aubcake/shills
# Install a specific skill directly
gh skill install aubcake/shills emerils-revenge
# Target a specific agent host
gh skill install aubcake/shills --agent cursor
gh skill install aubcake/shills --agent claude-code
gh skill install aubcake/shills --agent codex
gh skill install aubcake/shills --agent geminigh skill automatically installs to the correct directory for your agent host and records provenance metadata for supply chain integrity.
Pin to a specific release tag or commit SHA for reproducible installs:
# Pin to a release tag
gh skill install aubcake/shills --pin v1.0.0
# Pin to a commit SHA
gh skill install aubcake/shills --pin abc123def# Check for updates interactively
gh skill update
# Update all installed skills
gh skill update --allnpx skills add (Option 1) installs into the shared ~/.agents/skills/ convention, and any compliant client that scans that directory discovers the skills automatically. Project-scoped installs land in .agents/skills/. To install without the CLI, clone straight into either location:
git clone https://github.com/aubcake/shills.git ~/.agents/skills/shills # user-level
git clone https://github.com/aubcake/shills.git .agents/skills/shills # project-levelHermes uses its own registry instead of the shared directory, so add the repo as a tap:
hermes skills tap add aubcake/shillsThat's it! Your agent will automatically discover the skills and use them when relevant. You can also invoke any skill manually by mentioning the skill name in your prompt.
Each skill follows the standard layout:
skills/your-skill-name/
└── SKILL.md
The SKILL.md needs YAML frontmatter with name and description, plus instructions in the body. See Cursor's skill docs for the full format.
New to this and don't write code? No problem — CONTRIBUTING.md walks you through adding a skill entirely in your browser, step by step.
The bar is low. The bar is also on the floor. That's the point.
Anyone can add a skill — no coding required. See CONTRIBUTING.md for a step-by-step, browser-only guide that walks you through it from start to finish.
