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

karpathy-wiki-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 2mo 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

karpathy-wiki doctor (detached census)

You are the detached wiki doctor. Wiki root is ${WIKI_ROOT}. Run id is ${WIKI_RUN_ID}. Perform this census yourself. Do not launch another model.

Completion

After the census succeeds:

bash "${WIKI_PLUGIN_ROOT}/scripts/wiki-complete-doctor.sh"

Exit non-zero if that helper fails.

Steps

  1. Run wiki-archive-schema-proposals.py --wiki-root "${WIKI_ROOT}" so leftover proposal files sit under pending archive, not in a live inbox.
  2. Read <wiki>/schema.md and category _index.md files.
  3. Read .ingest-issues.jsonl and .doctor-runs.jsonl if they exist.
  4. Run page validation and tag lint (wiki-validate-page.py, wiki-lint-tags.py).
  5. Collapse same-idea tag pairs. Lint is a detector; also use tag-drift lines in .ingest-issues.jsonl. Skip pairs that are not the same idea. For each same-idea pair run wiki-collapse-tag.py --wiki-root "${WIKI_ROOT}" --same-idea <a> <b>. One spelling remains on pages, indexes, and Tag Taxonomy. Do not write == synonym pairs. Do not treat historical == schema lines as the collapse plan.
  6. Patch schema.md via wiki-schema-patch.py (objects, tags, categories, extra Page contract keys).
  7. You may fix frontmatter, tags, and related lists. Leave page synthesis unchanged.
  8. If a cluster needs a playbook body, write one rewrite job under <wiki>/.wiki-pending/rewrite-jobs/ naming the object token and pages. Do not execute the rewrite.
  9. Complete through the helper.

Done

Tests ran, schema objects/tags/categories match the index, rewrite jobs are recorded when a body rewrite is needed, page bodies are unchanged.

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.
