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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00919 | $0.00919 |
| Opus 5.5 | $0.00368 | $0.00368 |
| Sonnet 5.5 | $0.00184 | $0.00184 |
| Haiku 4.5 | $0.00092 | $0.00092 |
Grade A, and why
karpathy-wiki AGENTS.md 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.
How it starts
The opening of the file, as written. The whole thing — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Active planning handoff
Before changing test policy or removing, merging, or demoting tests, read
docs/planning/2026-08-12-test-strategy-rightsizing-handoff.md.
The first phase is a read-only portfolio audit and must stop for human review.
Remove this pointer when that workstream is resolved.
Project ledger files
Use the global project-ledger convention when adding or pruning local
CHANGELOG.md, TODO.md, ISSUES.md, and IDEAS.md.
In this repository, ISSUES.md means a local known-problems scratchpad. It is
not the wiki issues command, not .ingest-issues.jsonl, not a GitHub Issues
replacement, and not a work-package manifest.
Recent Changes
- 2026-08-27: Schema-proposals retired. Ingest logs schema-drift; doctor archives leftover files. Init no longer creates that inbox.
- 2026-08-27: karpathy-wiki is a three-host plugin in marketplace toolboxmd (Codex, Claude Code, Grok Build). It is not the marketplace.
- 2026-08-27: Ingest must-augment clustered objects, silently patches
schema.md, and a detached
wiki doctorcensus runs on schema cadence (Grok xhigh, Codex max fallback). Doctor does not rewrite page bodies. - 2026-08-26: Read Step B uses per-index document frequency: rare terms
select, common terms (6+ hits, including tags on the index line)
AND-filter unless that would empty the set. Related-only ingest does
not append
sources:. - 2026-08-21: Split the old combined backlog into
CHANGELOG.md,TODO.md,ISSUES.md, andIDEAS.md.
If you are an AI agent
Before opening a PR against this repo:
- Read the PR template (when one exists) and answer every prompt; do not skip prompts you find redundant.
- Search for existing PRs on the same topic. Duplicates get closed.
- Verify a real problem exists. Cite the failing test, the wrong output, or the user-reported bug. Do NOT fabricate problem descriptions.
- Show your human partner the complete diff before submitting. Walk them through it.
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.
