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

refresh-index 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 1mo 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

Refresh File Index

Update the file index to reflect current workspace state.

Step 1: Load Configuration

Read memory/index_config.json to get exclusion patterns.

If config doesn't exist, use defaults:

  • Exclude: node_modules, .git, pycache, .venv, dist, build, *.pyc, .DS_Store

Step 2: Generate Fresh Index

Build exclusion flags from config, then run:

find . -type f [exclusion flags] -exec ls -lh {} \; 2>/dev/null

Step 3: Format and Write

Update memory/file_index.md:

  1. Update "Last updated" timestamp
  2. Regenerate directory tree
  3. Update file listings with current sizes/dates
  4. Add summary stats at top:
    • Total files indexed
    • Total size
    • Directories covered

Step 4: Report Changes

Compare with previous index if available:

  • New files added
  • Files removed
  • Files with size changes

Output summary to user.

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.
