At a glance

Launch the Brain Visualizer, a real-time 3D view of memory and relationships.

  • Works in 4 steps: Check if already running → Find the visualizer directory → Start the server (if NOT_RUNNING and… → …
  • Show your brain
  • SKILL.md covers Overview, Launch and Report to User
  • Calls npm and node

What it does

Brain is an agent skill from kbanc85/claudia. Launch the Brain Visualizer, a real-time 3D view of memory and relationships. Triggers on "show your brain", "visualize memory", "open the brain", "memory graph". See also: brain-monitor for a terminal dashboard alternative.

Its SKILL.md is about 950 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Terminal-based AI chief of staff. Remembers relationships, tracks commitments, helps you think strategically. Runs on Claude Code.

When your agent uses it

  • Show your brain
  • Visualize memory

Example prompts

  • “show your brain”
  • “visualize memory”
  • “open the brain”
  • “/brain”

Requirements

  • Node.js

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Check if already running
  2. Find the visualizer directory
  3. Start the server (if NOT_RUNNING and VISUALIZER_FOUND)
  4. Open browser (if ALREADY_RUNNING)

What it can do on your machine

Read from SKILL.md and the folder at commit eb63cec. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm
    • node

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Brain loads about 953 tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 158 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~58
When it runs · the whole SKILL.md, loaded when a task matches
~953

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 158 words (~953 tokens).

“Launch the Claudia Brain Visualizer, a real-time 3D cosmos visualization of my memory system showing entities, relationships, memories, and patterns as a swirling interactive force-directed graph.”
