Install the impeccable skill

A skill is a folder. Copy it into your agent's skills folder and the agent loads it when the task matches its description. 

git clone --depth 1 https://github.com/NousResearch/hermes-agent.git /tmp/hermes-agent
mkdir -p ~/.claude/skills
cp -r /tmp/hermes-agent/optional-skills/creative/impeccable ~/.claude/skills/impeccable
available in every project

In the Claude apps, zip the folder and upload it from the Skills settings. The folder on GitHub

Impeccable (upstream-maintained)

Catalog stub. This entry is maintained upstream at

pbakaus/impeccable: the project

ships and verifies a Hermes-native skill bundle under .hermes/skills/.

hermes skills install impeccable pulls the current bundle live from that

repo (quarantined and scanned like any hub install) — this directory holds

only the catalog metadata, so the vendored copy can never go stale.

Impeccable is a design language for AI coding agents: one skill exposing 23 sub-commands (/impeccable init, craft, shape, critique, audit, polish, bolder, quieter, distill, harden, onboard, animate, colorize, typeset, layout, delight, overdrive, clarify, adapt, optimize, extract, document, live), explicit anti-pattern guidance (overused fonts, purple gradients, nested cards, bounce easing), and a 61-rule deterministic detector CLI (npx impeccable detect) that needs no LLM or API key.

After install, start with:

/impeccable init
