Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00105 | $0.04093 |
| Opus 5 | $0.00053 | $0.02047 |
| Sonnet 5 | $0.00021 | $0.00819 |
| Haiku 4.5 | $0.00011 | $0.00409 |
Grade A, and why
create-wiki 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 6d 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 — 411 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Create Wiki
Set up a persistent, LLM-maintained knowledge base inside a project following Andrej Karpathy's LLM Wiki pattern. The wiki uses a three-layer architecture:
- Sources (
wiki/sources/) — Human-curated raw documents. Immutable. Claude reads but never modifies. - Pages (
wiki/pages/) — LLM-generated markdown pages. Claude owns these entirely — creates, updates, deletes as needed. - Schema (
wiki/schema.yaml) — Configuration defining categories, conventions, and maintenance thresholds. Co-evolves with use.
The key insight: the tedious part of maintaining a knowledge base is not the reading or thinking — it's the bookkeeping. LLMs excel at updating cross-references and maintaining consistency across dozens of pages without fatigue. Humans curate sources and ask questions. Claude handles everything else.
Input
Arguments: $ARGUMENTS
Supported arguments:
init— Full initialization: discover project context, create wiki structure, seed pages, inject CLAUDE.md rulesstatus— Show wiki health (redirects to/wiki status)- No arguments — Same as
initif no wiki exists, same asstatusif one does
Phase 0: Self-Invocation Confirmation
This skill can be model-invoked, and initialization writes a wiki/ tree and injects
maintenance rules into CLAUDE.md that change how Claude behaves for the rest of the
project's life. That must never happen unasked.
If you are invoking this skill on your own initiative — because the project is
accumulating domain knowledge, context keeps getting lost between sessions, or the user said
"I keep forgetting how this works" — rather than the user typing /create-wiki, confirm
first with AskUserQuestion:
{
"questions": [
{
"question": "Set up an LLM-maintained wiki for this project?",
"header": "Wiki",
"multiSelect": false,
"options": [
{
"label": "Yes, initialize it",
"description": "Creates wiki/ with sources, pages, schema, and index, seeds pages from project discovery, and adds maintenance rules to CLAUDE.md"
},
{
"label": "No, not now",
"description": "Nothing is written; you can run /create-wiki yourself at any time"
}
]
}

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.

create-wiki is a skill published in the GitHub repository davistroy/claude-marketplace (5 stars, last pushed 3d ago), licensed MIT. It adds 105 tokens to every session and 4,093 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
