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

notebook 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 10d 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.

Notebook Skill

A workflow for performing search, browse, organize, and stats operations on the Notebook.

Prerequisites

First check the NOTEBOOK_PATH environment variable.

If not set:

Notebook is not configured.

Setup instructions:
1. Create a git repository for your Notebook
2. Add the following to .claude/settings.local.json:
   {
     "env": {
       "NOTEBOOK_PATH": "/path/to/your/notebook-repo"
     },
     "permissions": {
       "additionalDirectories": ["/path/to/your/notebook-repo"]
     }
   }
3. Restart Claude Code

Display this and exit. The following workflow only executes when Notebook is configured.

Workflow

Step 1: Determine the Operation

Classify the user's request into one of these operations:

Operation Trigger Examples
search "find...", "any records about...?", "anything saved about...?"
browse "show recent records", "list entries", "what's in the Notebook?"
organize "organize tags", "update cross-references", "add related links"
stats "Notebook statistics", "how much is stored?", "show breakdown"

Step 2: Execute the Operation

Operate directly on the $NOTEBOOK_PATH path using the following tools.

search
  1. Glob for filename matching
  2. Grep frontmatter tags, title, type for matching
  3. Grep body for keyword matching

Output results in this format:

  • File path, title, type, date
  • Relevant snippet (2 lines before/after the match)
browse
  1. Glob to retrieve all entries
  2. Read frontmatter of each file
  3. Group by type, sort by date descending
organize
  1. Read target entries
  2. Edit frontmatter tags / related fields
  3. Update index.md (table format with date, title, type, path)

Confirm changes with the user before making modifications.

stats
  1. Glob to count all entries
  2. Grep to aggregate by type and project
  3. Aggregate tag frequency

Step 3: Format and Output Results

Format operation results for easy reading and present to the user.

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.
