How to use the Digital Brain agent skill: setup and examples
Updated · written with AI from the project's own documentation and checked against our catalogue data
The Digital Brain is an agent skill: a set of instructions and helper scripts that lets an AI agent work with a folder of your personal data. It covers content drafts in your saved voice, contact lookups before meetings, interaction logs, goal tracking and a weekly review. This guide explains what the skill does, how to install it, how to trigger it with plain requests, and what to check before you rely on it.

- 1Download and unzip. Download the ZIP from this page and unzip the digital-brain folder.
- 2Place the skill. Put it in ~/.claude/skills/ for personal use or in a project's .claude/skills/ folder, or upload it under Settings → Capabilities → Skills.
- 3Install Python 3. The helper scripts in agents/scripts/ require Python 3.
- 4Populate identity/voice.md. Write down your tone, style and vocabulary so drafts match your voice.
- 5Add contacts and ideas. Fill network/contacts.jsonl and content/ideas.jsonl with your own entries.
- 6Make a request. Ask in plain language, such as writing a post or preparing for a meeting.
What is an agent skill and what does Digital Brain do?
An agent skill is a folder of instructions and optional scripts that an AI agent loads when a task matches the skill's description. The Digital Brain skill is written for personal operating-system workflows: content creation, voice consistency, relationship lookup, meeting preparation, weekly review, goal tracking, personal brand management and network management.
It works on a structured folder of personal data. The agent reads these files when you ask and updates them as you go. The source describes voice notes, content ideas, drafts, contacts, interactions, todos and goals.
- Draft posts, threads and newsletters that follow your saved voice (identity/voice.md).
- Pull up background on a contact before a meeting from network/contacts.jsonl and network/interactions.jsonl.
- Log meetings and calls to interactions.jsonl.
- Flag contacts you have not reached out to recently, using a script.
- Compile a weekly review from your data files, using a script.
Install the Digital Brain skill from the ZIP
Download the ZIP from this page and unzip it. You can install it in one of two places. For a personal setup available across projects, unzip it into ~/.claude/skills/. For a single project, unzip it into that project's .claude/skills/ folder.
If you use the Claude apps, you can instead upload the skill under Settings → Capabilities → Skills.
- Personal: ~/.claude/skills/
- Project only: .claude/skills/ inside your project folder
- Claude apps: Settings → Capabilities → Skills, then upload
Set up your data files before you use it
The skill does not come with your personal information. You need to populate the data yourself. The minimum the source names is a local copy of the digital-brain folder with your own data files, including identity/voice.md and the content and network JSONL files.
Start with identity/voice.md, because the skill is designed to read it before writing any content. Then add contacts and content ideas as you go. The files are plain JSON, JSONL and Markdown, so you can open and edit them in any text editor.
- identity/voice.md: your tone, style, vocabulary and patterns.
- content/ideas.jsonl and content/posts.jsonl: ideas and published posts.
- network/contacts.jsonl and network/interactions.jsonl: people and interaction history.
- operations/todos.md and operations/goals.yaml: tasks and goals.
Trigger the skill with natural requests
You do not need special syntax. Ask in plain language and the agent will load the skill when your request matches its trigger phrases. The source lists phrases such as "write a post", "my voice", "content ideas", "who is [name]", "prepare for meeting", "weekly review", "save this" and "my goals".
Mention the platform or format when it matters, for example a post, a thread or a newsletter.
- "Help me write a post about AI agents"
- "Prepare me for my call with Sarah Chen"
- "Run my weekly review"
- "Who is [name]?" to look up a contact
- "What are my goals?"
Run the helper scripts
The skill includes Python scripts in agents/scripts/. The weekly review script compiles a summary from your data files, and the stale contacts script lists people you have not contacted in a while. The agent can run these when needed, or you can run them yourself from the digital-brain folder.
The source gives this weekly review sequence: run the weekly review script, review metrics, check stale contacts, update goal progress, and plan the next week in content/calendar.md.
- content_ideas.py: generates content ideas from knowledge.
- idea_to_draft.py: expands an idea into a draft.
- stale_contacts.py: finds contacts needing outreach.
- weekly_review.py: generates a weekly review from data.
- metrics_snapshot.py: compiles metrics for tracking (listed in the agents module, not among the reviewed files).
python agents/scripts/weekly_review.pySafety notes before you install
The skill runs scripts and stores names, meeting notes and interaction history in plain files. Review the scripts before running them, and keep the data folder on a machine and account you control.
The source says the skill does not use the network. It also says the data lives in files you maintain. It does not describe any sync with email, calendars or social platforms, so do not expect that. Avoid using it in shared or team environments where third parties' contact details could be exposed.
- Runs scripts: yes. Requires Python 3.
- Uses network: no, according to the source.
- Stores personal and third-party data in plain text files.
- Does not sync with email, calendar or social platforms in the files reviewed.
- Append-only rule: the skill archives entries rather than deleting them.
What people use it for
- Drafting a LinkedIn post, thread or newsletter in a consistent voice.
- Getting a pre-meeting brief with a contact's role, last discussion and follow-ups.
- Running a weekly review that summarises data files and reminds you of stale contacts.
- Tracking goal progress and planning the next week's content calendar.
Frequently asked questions
Is the Digital Brain skill free?
The source reviewed is published under the MIT licence, which is stated on this page. The files do not mention pricing, so check the licence text in the download for the exact terms.
What do I need to run the Digital Brain skill?
You need Python 3 to run the scripts in agents/scripts/, and a local copy of the digital-brain folder with your own data files populated. The skill is designed to read identity/voice.md before writing content.
Where do I install a Claude agent skill?
Unzip the ZIP into ~/.claude/skills/ for personal use or into a project's .claude/skills/ folder. In the Claude apps you can upload it under Settings → Capabilities → Skills.
Does Digital Brain sync with my email, calendar or social accounts?
No integrations of that kind appear in the files reviewed. The skill works on local JSON, JSONL and Markdown files that you maintain yourself.
Does the skill send my data over the internet?
The source states that the skill does not use the network. It does run Python scripts, so review them before running.
Why does the skill never delete entries?
Its guidelines say JSONL files are append-only. Entries are marked as archived instead, which preserves history for later pattern analysis.

Our verdict
Digital Brain suits founders and creators who publish regularly and want drafts in a consistent voice, and professionals who want a simple personal CRM kept in plain files. Skip it if you do not want personal contacts and goals stored in files you maintain, if you need automatic sync with email or calendars, or if you work in a shared environment where third-party contact data could be exposed.
