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

attachment-audit 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 8d 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.

/attachment-audit

Audit all images and attachments in the vault using Sonnet sub-agents for comprehensive visual analysis.

Usage

/attachment-audit
/attachment-audit --type images
/attachment-audit --unused
/attachment-audit --folder +Attachments/2025

Instructions

This skill uses Sonnet model sub-agents for thorough analysis of vault attachments.

Phase 1: Inventory

  1. Scan +Attachments/ folder for all files
  2. Categorise by type (images, PDFs, documents)
  3. Build list of files to analyse

Phase 2: Comprehensive Analysis (Sonnet Sub-Agents)

Launch these sub-agents using model: "sonnet":

Agent 1: File Inventory (Sonnet)

Task: Build complete attachment inventory
- List all files in +Attachments/ recursively
- Categorise by file type
- Get file sizes and modification dates
- Identify naming patterns
- Note any duplicates or similar names
Return: Complete file inventory with metadata

Agent 2: Usage Analysis (Sonnet)

Task: Analyse attachment usage across vault
- Search all markdown files for attachment references
- Map each attachment to notes that reference it
- Identify orphan attachments (not referenced anywhere)
- Find broken references (links to non-existent files)
- Note most frequently used attachments
Return: Usage map with orphan and broken link lists

Agent 3: Image Content Analysis (Sonnet)

Task: Analyse image contents for documentation
- For each image, read and analyse visually
- Categorise: screenshot, diagram, photo, document, other
- Identify what each image depicts
- Extract any visible text
- Note which images might need better filenames
- Identify potentially sensitive content
Return: Image content summary for each file

Agent 4: Organisation Recommendations (Sonnet)

Task: Recommend organisation improvements
- Assess current folder structure
- Identify files that should be renamed
- Suggest categorisation (by project, date, type)
- Find large files that could be compressed
- Recommend archival candidates
- Suggest metadata or tagging approach
Return: Organisation recommendations

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.
