# Loom Skills Catalog Loader ## Overview Ten loom mechanics skills stay installed into `~/.codex/skills/`, indexed by Codex with their `description:` kept resident in every request. The other fifty-three domain skills install instead into `~/.codex/loom-skill-catalog/<name>/SKILL.md` — a directory Codex does not scan, so they cost nothing resident. This skill is the bridge: it loads one of those catalogued skills on demand. ## How to Load Invoked with an argument, read `~/.codex/loom-skill-catalog/<argument>/SKILL.md` in full with `cat` or, for a long file, with `sed -n '<first>,<last>p'`, then follow it as if it had been loaded directly. The argument is the full skill name, for example `loom-rust`. **Several names may be passed at once**, separated by whitespace or commas, for example `loom-ci-cd loom-rust`. Split the argument and load EACH name by the rules below, in the order given. Never treat the whole string as one skill name — `~/.codex/loom-skill-catalog/loom-ci-cd loom-rust/SKILL.md` is not a path that can exist, and reporting it as a missing catalog is wrong. If a name's path does not exist, try `~/.codex/skills/<name>/SKILL.md` — an install made with `--skills all` keeps every skill in the indexed directory and has no catalog directory at all. If neither path exists for a name, say which name did not resolve and continue with the ones that did. Report the catalog as not installed ONLY when `~/.codex/loom-skill-catalog/` is itself absent AND the name is missing from `~/.codex/skills/` — a single unresolved name means a bad name, not a broken install. Invoked with no argument, show the table below and pick the skill that fits the task. ## Catalog | Skill | Summary | | --- | --- | | `loom-accessibility` | Web accessibility, WCAG compliance,
