Use the installed skill library

Run scripts/skill-library list from this skill's directory. It reads the generated host catalog at ${XDG_STATE_HOME:-~/.local/state}/agent-skills/catalog.json. The catalog covers all default-disabled local plugins and declared upstream plugins resolved through Claude's user installation inventory. These files can be read from either Codex or Claude; their presence does not enable a plugin. Unavailable installations appear as coverage diagnostics.

Choose only entries relevant to the user's task. Preserve the full description's conditions, including requests that must name a skill explicitly. If no entry fits, continue the task without loading one. Prefer a skill already available in the current native catalog over loading another copy from this library.

Run scripts/skill-library read MARKETPLACE/PLUGIN/SKILL for a selected read entry. Read its complete instructions before proceeding, and honor any narrower conditions in its body. Resolve supporting files and scripts from the printed skill directory. Reading instructions does not authorize their side effects.

Entries marked explicit remain searchable but require the user to request that skill. Only then pass --explicit. Entries marked native require native plugin invocation; do not emulate their hooks, tools, permissions, argument expansion, model selection or fork behavior through a file read. Explain the needed native enablement when it blocks the requested task; never change activation merely to search the library.

If the catalog is absent, stale, or a path is missing, report that limitation. In the dotfiles checkout, regenerate it with .agents/skills/agent-skill-management/scripts/generate-skill-library after materialization. Normal script 36 apply also regenerates it. Do not guess cache versions or search unselected vendor trees for substitutes.

The library loads instructions into the current conversation. It does not register slash commands, unload instructions, or guarantee retention after compaction. Resume through the same verified entry if its instructions are needed again.
