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 | $0.00085 | $0.01126 |
| Opus 5 | $0.00043 | $0.00563 |
| Sonnet 5 | $0.00017 | $0.00225 |
| Haiku 4.5 | $0.00009 | $0.00113 |
Grade B, and why
llmwiki-sync scanned grade B 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 9d 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
If the user wants the converter to run automatically on every Claude Code session start, offer to add this to `~/.claude/settings.json`: How it starts

llmwiki-sync
What this skill does
The user maintains a Karpathy-style LLM Wiki — a local, file-based knowledge base compiled from their Claude Code (and Codex CLI) session transcripts.
This skill runs the full sync pipeline:
~/.claude/projects/*/*.jsonl (raw session transcripts)
│
▼ python3 -m llmwiki sync
llmwiki/raw/sessions/<proj>/*.md (Karpathy layer 1 — immutable markdown)
│
▼ /wiki-ingest (Claude in the loop)
llmwiki/wiki/sources, entities, (Karpathy layer 2 — LLM-maintained wiki)
concepts, syntheses
│
▼ python3 -m llmwiki build
llmwiki/site/ (Karpathy layer 3 — static HTML)
When to use
Invoke this skill when the user:
- Says "sync the wiki", "update llmwiki", "ingest recent sessions", "refresh the knowledge base"
- Asks a knowledge question that would benefit from the latest sessions ("what have I been working on this week?") — run sync first, then
/wiki-query - Starts a new project and wants context from past work
- Says "what's new" or "catch me up" in a context where session history matters
Do NOT invoke when:
- The user is asking a question unrelated to their own work
- The tool is not installed (check for
llmwiki/directory first)
Workflow
-
Locate the llmwiki install. Check the current working directory and common locations:
./(if cwd containsllmwiki/package)~/Desktop/2026/production-draft/llmwiki/~/llmwiki/$LLMWIKI_HOMEenvironment variable
If you can't find it, tell the user and stop.
-
Run the converter (idempotent — safe to re-run):
cd <llmwiki-dir> python3 -m llmwiki syncCapture the summary line:
N converted, M unchanged, K live, J filtered, X errors. -
If N == 0, report that the wiki is up to date and stop.
-
If N > 0, ingest the new files into the wiki using the Ingest Workflow from the repo's
CLAUDE.md. Process one project at a time. If more than 20 new files, ask the user whether to process all or a subset first.
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.

llmwiki-sync is a skill published in the GitHub repository Pratiyush/llm-wiki (386 stars, last pushed 2mo ago), licensed MIT. It adds 85 tokens to every session and 1,126 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
