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

check-versions 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

Use the terminal tool to run bash scripts/check-versions.sh in the workspace root. It scans manifests under the current directory and compares each dependency version to the latest upstream. Supported (v0.1): package.json, requirements*.txt, pyproject.toml, Cargo.toml, *.csproj.

Relay the full output to the user, then interpret it briefly:

  • DRIFT rows: current ≠ latest with no intentional: record. Suggest looking up the latest version and recording it with bash scripts/vs-record.sh <ecosystem> <pkg> <version> <source-url> before bumping.
  • intentional-pin rows: deliberate pins with a recorded reason — no action needed unless the pin is stale.
  • lookup-failed rows: registry fetch failed; suggest re-running once, then checking the registry URL manually.

This audit reports drift without blocking anything.

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.
