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

doctor 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

Resolution order for the doctor script:

  1. $IJFW_REPO/scripts/doctor.sh -- if $IJFW_REPO is set (dev-tree override).
  2. $IJFW_HOME/scripts/doctor.sh -- if $IJFW_HOME is set (custom install root).
  3. $HOME/.ijfw/scripts/doctor.sh -- default install location.

If none of those paths resolve, surface: IJFW doctor script not found -- run \npm install -g @ijfw/install && ijfw install` to restore it.`

Run the resolved script with bash <path>. Report the output as-is. Do not summarize -- the doctor output is already positive-framed and scannable.

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.
