brain-sync

brain-sync is a skill for Claude Code, Codex from toroleapinc/claude-brain. It costs 30 tokens per session (223 once invoked), scanned A, original, MIT.

A procedure for synchronising an agent's local state with a remote copy across machines. It exports local changes, downloads updates, merges them, and applies the result.

In plain words
What is it for?
Use it to run a full manual sync, review what changed, and find conflicts that need separate resolution.
Why use it?
It keeps skills, memory, and settings aligned between machines and identifies conflicts when both copies changed.

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

brain-sync scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

The user wants to manually trigger a full brain sync cycle.

Steps

  1. Check that brain is initialized:

    if [ ! -f ~/.claude/brain-config.json ]; then
      echo "Brain not initialized. Run /brain-init first."
      exit 1
    fi
    
  2. Push local changes:

    bash "${CLAUDE_PLUGIN_ROOT}/scripts/push.sh"
    
  3. Pull and merge remote changes:

    bash "${CLAUDE_PLUGIN_ROOT}/scripts/pull.sh" --auto-merge
    
  4. Show the sync result summary. Check:

    • What changed (new skills, merged memory, updated settings)
    • Any conflicts that need resolution
    • Updated sync timestamps
  5. If there are conflicts, suggest: "Run /brain-conflicts to review and resolve."

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
