cortex-snapshot

cortex-snapshot is a command for Claude Code from Peaky8linders/claude-cortex. It costs 11 tokens per session (228 once invoked), scanned A, original, MIT.

A command that saves a dated copy of the current knowledge graph's notes and connections. It also records graph statistics and keeps only the ten newest copies.

In plain words
What is it for?
Use it to regenerate graph views, capture node and connection counts, and save timestamped copies of the graph files.
Why use it?
It creates restore points before the graph changes, so its previous state can be inspected or recovered. Without snapshots, older graph data may be harder to compare.

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

cortex-snapshot 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 3d 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

Save a snapshot of the current knowledge graph state.

  1. Run brainiac stats to capture current metrics:
    cd ~/.claude/knowledge && python -m brainiac stats
    
  2. Run brainiac render to regenerate all markdown views:
    cd ~/.claude/knowledge && python -m brainiac render
    
  3. Create a timestamped snapshot:
    TIMESTAMP=$(date +%Y%m%d_%H%M%S)
    mkdir -p ~/.claude/knowledge/snapshots
    cp ~/.claude/knowledge/graph/nodes.json ~/.claude/knowledge/snapshots/nodes_${TIMESTAMP}.json
    cp ~/.claude/knowledge/graph/edges.json ~/.claude/knowledge/snapshots/edges_${TIMESTAMP}.json
    
  4. Keep only the last 10 snapshots (delete older ones)
  5. Report the snapshot path and stats (node count, edge count, timestamp)
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.
