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 | $0.00056 | $0.01342 |
| Opus 5 | $0.00028 | $0.00671 |
| Sonnet 5 | $0.00011 | $0.00268 |
| Haiku 4.5 | $0.00006 | $0.00134 |
Grade A, and why
add-karpathy-llm-wiki scanned grade A with 1 finding 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 12d 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.

Add Karpathy LLM Wiki
Set up a persistent wiki knowledge base on NanoClaw, based on Karpathy's LLM Wiki pattern.
Step 1: Read the pattern
Read ${CLAUDE_SKILL_DIR}/llm-wiki.md — this is the full LLM Wiki idea as written by Karpathy. Understand it thoroughly before proceeding. Summarize the core idea to the user briefly, then discuss what they want to build.
Step 2: Choose a group
AskUserQuestion: "Which group should have the wiki?"
- Main group — add to your existing main chat
- Dedicated group — create a new group just for the wiki
- Other — pick an existing group
If dedicated: ask which channel and chat, then register with npx tsx setup/index.ts --step register.
Step 3: Design collaboratively
Discuss with the user based on the pattern:
- What's the wiki's domain or topic?
- What kinds of sources will they add? (URLs, PDFs, images, voice notes, books, transcripts)
- Do they want the full three-layer architecture or a lighter version?
- Any specific conventions they care about? (The pattern intentionally leaves this open.)
Based on this discussion, create three things:
3a. Directory structure
Create wiki/ and sources/ directories in the group folder. Create initial index.md and log.md per the pattern's Indexing and Logging section. Adapt to the user's domain.
3b. Container skill
Create a container/skills/wiki/SKILL.md tailored to this user's wiki. This is the schema layer from the pattern — it tells the agent how to maintain the wiki. Base it on the pattern's Operations section (ingest, query, lint) and the conventions you agreed on with the user. Don't over-prescribe — the pattern says "your LLM figures out the rest."
3c. Group CLAUDE.md
Edit the group's CLAUDE.md to add a wiki section. This is critical — it's what turns the agent into a wiki maintainer. It should:
- Explain the wiki system concisely: what it is, the three layers (sources, wiki, schema), the three operations (ingest, query, lint)
- Index the key files and folders (
wiki/,sources/,wiki/index.md,wiki/log.md) - Point to the container skill for detailed workflow
- Ingest discipline: Be very explicit that when the user provides multiple files or points at a folder with many files, the agent MUST process them one at a time. For each file: read it, discuss takeaways, create/update all wiki pages (summary, entities, concepts, cross-references, index, log), and completely finish with that file before moving to the next. Never batch-read all files and then process them together — this produces shallow, generic pages instead of the deep integration the pattern requires.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

add-karpathy-llm-wiki is a skill published in the GitHub repository chiptoe-svg/nanoclaw_flexagents (5 stars, last pushed 4mo ago), licensed MIT. It adds 56 tokens to every session and 1,342 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 86% identical to add-karpathy-llm-wiki, differing in 57 lines, and is treated as a copy.
