Included Skills10

auto-updaterskills/auto-updater/SKILL.md

Check installed community skills for updates. Shows a diff and requires explicit approval before applying. Use when the user says "check for updates", "update my skills", "anything new for my installed skills", or when invoked from the registry-sync agent.

cold-start-interviewskills/cold-start-interview/SKILL.md

Practice-profile interview that recommends and installs a starter pack of community legal skills. This IS the cold start for the whole ecosystem — it asks what kind of lawyer you are and recommends what to install first. Use on fresh install, when the user says "get me started" or "what should I install", or to re-run the integration-availability check after adding or removing an MCP connector.

customizeskills/customize/SKILL.md

Guided customization of your Legal Builder Hub profile — change one thing without re-running the whole cold-start interview. Adjust practice profile, installed starter pack, watched registries, update preferences, or QA strictness. Use when the user says "change my [thing]", "add a registry", "update my profile", "edit my config", or "customize".

disableskills/disable/SKILL.md

Disable a community skill installed through the hub without removing its files. Use when the user wants to temporarily quiet a community skill ("disable [skill]"), stop its hooks from firing while keeping its config, or re-enable a previously disabled skill.

registry-browserskills/registry-browser/SKILL.md

Search watched registries for community legal skills, showing matches with descriptions and offering to show the full SKILL.md before install. Use when the user says "browse", "search skills", "find a skill for", "what's out there for", or wants to add a new registry to the watchlist.

related-skills-surfacerskills/related-skills-surfacer/SKILL.md

Suggest community skills based on recent activity in other plugins. Checks whether the community has built something relevant to a task and mentions it once, non-intrusively. Use when the user says "is there a community skill for this", "what else is out there", or asks for skill recommendations; also runs passively as part of other plugins' workflows.

skill-installerskills/skill-installer/SKILL.md

Install a community skill from a watched registry. Reads the allowlist first, fetches, shows the RAW SKILL.md (not just a summary), runs structural trust checks, runs skills-qa, and only writes files after explicit user approval. Use when the user says "install [skill]", picks install from browse, or provides a direct skill URL.

skill-managerskills/skill-manager/SKILL.md

Reference: detailed uninstall, disable, and re-enable workflows for community skills installed via the legal builder hub. Safe by default — refuses to touch first-party plugin skills, confirms before removing files, and logs every action. Loaded by the /legal-builder-hub:uninstall and /legal-builder-hub:disable skills.

skills-qaskills/skills-qa/SKILL.md

Evaluate a skill against the Legal Skill Design Framework — thirteen design parameters (including trust-surface, freshness, schema validation, and conflict detection), three legal failure modes, and a three-band verdict (Ready / Some Concern / Material Concerns). Use when deciding whether to trust a community skill before installing it, before deploying a first-party skill to your team, or whenever the user asks "should I trust this?" or "is this skill well-designed?". Runs automatically as part of /legal-builder-hub:skill-installer.

uninstallskills/uninstall/SKILL.md

Uninstall a community skill that was installed via the hub. Confirms before deleting files, refuses to touch first-party plugin skills, and logs every action. Use when the user wants to fully remove a community skill ("uninstall [skill]", "remove this skill") rather than just disable it.
