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

upgrade-js-deps 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.

What it actually says

Your task

Upgrade all JavaScript dependencies and verify nothing is broken.

Step 1: Check for available upgrades

Run npx npm-check-updates to see what upgrades are available. Review the output and present the list to the user.

Step 2: Update package.json

Run npx npm-check-updates -u to update package.json with the new versions.

Step 3: Install updated dependencies

Run make npm-install to install the upgraded dependencies and update package-lock.json.

Step 4: Run post-upgrade checks

Run these checks sequentially, stopping if any step fails:

  1. TypeScript type checking: Run make npm-type-check and report any new type errors.
  2. Build: Run make npm-build to verify the production build still works.
  3. Tests: Run make test to verify the test suite still passes.

Step 5: Summarize and commit

Summarize what was done:

  • Which packages were upgraded (notable version changes)
  • Whether any type errors were introduced
  • Whether the build succeeded
  • Whether all tests passed
  • Any issues that need manual attention

If there were failures, present the issues and ask how the user wants to proceed.

If everything passed, ask the user if they'd like to commit the changes. If yes, commit using the /commit skill.

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.
