How to use the Customize Legal Builder Hub agent skill
Updated · written with AI from the project's own documentation and checked against our catalogue data
The customize skill is an agent skill for the Legal Builder Hub, part of Anthropic's claude-for-legal project. It lets you change one part of a profile you have already set up, such as your practice areas, watched community skill registries, update preferences, or how strictly skills are checked before install. This guide explains what the skill does, how to install it, how to trigger it with plain requests, and what to watch for, so you can make a single change without editing config files by hand.
Customize Legal Builder Hubanthropics/claude-for-legal · Apache-2.0 Download the skill Quick start
- 1Confirm setup is done. Make sure the Legal Builder Hub setup interview has been completed and that config files exist in ~/.claude/plugins/config/claude-for-legal/.
- 2Download and unzip the skill. Download the customize ZIP from the directory page and unzip it into ~/.claude/skills/ or a project's .claude/skills/ folder.
- 3Start the skill. Run /legal-builder-hub:customize, or describe the change you want in plain words.
- 4Pick a section. Review the map of your settings with current values and choose the section to change.
- 5Give the new value. Tell the agent the new value you want, and it will show the current value for comparison.
- 6Confirm downstream effects. Read the explanation of what the change affects, then confirm so the agent writes it to the config.
What an agent skill is and what customize does
An agent skill is a folder containing a SKILL.md file that gives an AI agent instructions for one task. The agent loads the instructions when a request matches the skill's description. The customize skill is licensed under Apache-2.0 and is distributed as SKILL.md.
When it runs, the agent reads your existing saved configuration, shows you a map of your settings with their current values, makes the change you pick, and explains what that change affects. It does not re-run the whole setup interview, and you do not edit YAML yourself.
- Shows a grouped map: company profile, practice profile, installed starter pack, watched registries, update preferences, QA strictness, skill install defaults, and integrations
- Changes one setting at a time and confirms before writing it
- Explains downstream effects, for example which command will pick up a new registry
Check the requirements before you install
The skill needs Claude Code or a compatible agent with the claude-for-legal Legal Builder Hub plugin installed. You must also have completed the Legal Builder Hub setup, which creates plugin config files in ~/.claude/plugins/config/claude-for-legal/.
The skill runs no scripts and uses no network access, according to its listing. If you have not completed setup, the skill will stop and ask you to run the cold-start setup interview first.
- Claude Code or compatible agent with the Legal Builder Hub plugin installed
- Completed Legal Builder Hub setup, with config files in ~/.claude/plugins/config/claude-for-legal/
- Runs scripts: no
- Uses network: no
Install the customize skill
Download the ZIP for the customize skill from the directory page and unzip it. Place the resulting skill folder in one of two locations: your user skills folder at ~/.claude/skills/ to make it available everywhere, or a project's .claude/skills/ folder to limit it to that project.
If you use the Claude apps instead, upload the ZIP under Settings → Capabilities → Skills.
- User-wide: unzip into ~/.claude/skills/
- Single project: unzip into the project's .claude/skills/ folder
- Claude apps: upload the ZIP under Settings → Capabilities → Skills
Trigger the skill with a natural request
You can invoke the skill with the slash command /legal-builder-hub:customize, optionally followed by a section name or a description of what you want to change. You can also just describe the change in ordinary words. The skill's description lists phrases such as "change my [thing]", "add a registry", "update my profile", "edit my config", and "customize".
If you are not sure which section to pick, run the command without an argument and the agent will show the full map first.
- "Add a registry" to add a community skill source
- "Change my update notifications to Slack" or similar wording for update preferences
- "Update my practice areas" to change what community skills are recommended for
- "Set QA strictness to middle" to adjust how skills are checked before install
/legal-builder-hub:customizeExamples of changes and what they affect
The skill tells you what each change does before it writes anything. Adding a watched registry means the registry browser will search it alongside your existing ones, and the auto-updater will check it on its next run. Lowering QA strictness from strict to middle means the QA check reports the same findings but does not block install on the medium band unless you confirm.
Turning auto-update off means the hub will prompt you before applying updates instead of applying them automatically. Changes to company name, industry, jurisdictions, practice setting, or stage are written to company-profile.md and affect all 12 plugins.
- Add a registry: the registry browser and auto-updater both pick it up
- Strict to middle QA: findings are still reported, but install is not blocked on the medium band without confirmation
- Auto-update off: you are prompted before updates are applied
- Removing a registry: the skill offers to mark it [Paused] instead of deleting it
Safety notes and limits
The skill will not delete a section. If you ask to remove a watched registry, it offers to pause it, which keeps the install history but stops update checks. The skill also flags inconsistencies, such as auto-update on with QA strictness off, or a practice profile that matches no installed plugin.
The skill does not let you turn off skill quality checks entirely. Its guidance is to keep them on at the middle setting. The checks cover nine design parameters, three legal failure modes, and a trust-surface check, which are what /skills-qa is meant to run. Turning them off would weaken safeguards against unsafe or poorly designed skills.
- Removing a registry pauses it rather than deleting it
- The skill flags settings that conflict with each other
- Recommended QA setting is middle, not off
Tips for smooth changes
Make one change per request. The skill is built around changing a single setting and does not re-ask the whole interview. If you need several changes, run the skill once for each.
Before a change to a shared setting, remember that it affects every plugin that reads your company profile. Read the confirmation message carefully so you know what will change downstream.
- Change one setting at a time
- Describe the change in your own words if you do not know the section name
- Check the confirmation text for downstream effects before accepting
What people use it for
- Adding a community skill registry so the registry browser searches it
- Changing how often the hub checks for updates or where it sends notifications
- Lowering QA strictness from strict to middle after reviewing findings
- Switching auto-update off so you are prompted before updates apply
- Updating the jurisdictions or practice setting in the shared company profile
Frequently asked questions
Is the customize skill free?
The source material for this listing does not state pricing. It is published under the Apache-2.0 licence, which you should read directly in the repository to confirm the terms.
What do I need before I can use the customize skill?
You need Claude Code or a compatible agent with the claude-for-legal Legal Builder Hub plugin installed, and you must have completed the Legal Builder Hub setup. The setup creates config files in ~/.claude/plugins/config/claude-for-legal/. Without these, the skill will ask you to run the cold-start setup interview first.
Where do I install the customize skill?
Unzip the downloaded ZIP into ~/.claude/skills/ for use everywhere, or into a project's .claude/skills/ folder for one project. In the Claude apps, upload the ZIP under Settings → Capabilities → Skills.
Can I use customize to add a new registry?
Yes. Ask to add a registry, or run /legal-builder-hub:customize and choose watched registries. The registry browser will then search the new registry alongside your existing ones, and the auto-updater will check it on its next run.
Can I turn off QA strictness completely?
The skill does not support turning off the checks. It recommends the middle setting instead, because the checks guard against unsafe or poorly designed skills. Lowering strictness from strict to middle keeps the findings but stops blocking install on the medium band unless you confirm.
Does the customize skill run scripts or use the internet?
According to its listing, the skill runs no scripts and uses no network access. It reads and writes your local plugin configuration files.

Our verdict
Use customize if you have already finished Legal Builder Hub setup and want to change one setting, such as a registry, update preference, or QA strictness, without editing config files by hand. Do not use it as a first-time setup tool, and do not expect it to turn off skill quality checks; if you need full control over the framework itself, edit the configuration yourself or choose a different tool.
