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 | $0.00253 | $0.02125 |
| Opus 5 | $0.00127 | $0.01063 |
| Sonnet 5 | $0.00051 | $0.00425 |
| Haiku 4.5 | $0.00025 | $0.00213 |
Grade A, and why
wiki-lint 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 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.
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 — 205 lines — stays where its author put it; the contents beside it link to each section on GitHub.
wiki-lint
Health-check an existing Karpathy-style LLM wiki. The pattern this skill follows is described in https://gist.github.com/karpathy/442a6bf555914893e9891c11519de94f.
Karpathy's lint description, verbatim:
Periodically, ask the LLM to health-check the wiki. Look for: contradictions between pages, stale claims that newer sources have superseded, orphan pages with no inbound links, important concepts mentioned but lacking their own page, missing cross-references, data gaps worth filling with a web search.
He also notes the LLM is good at suggesting new questions to investigate and new sources to look for. Treat that as a seventh, forward-looking output of lint.
Lint reports; it does not fix. Every finding is advisory. The
user decides which ones warrant action, and fixes happen through
wiki-ingest (when a new source corrects or extends the claim) or
through direct edits on the relevant page. Auto-rewriting during a
health check would defeat the point.
Prerequisites
- A wiki exists. If not, run
wiki-initfirst. - The llm-wiki-mcp server is wired into this session. If
wiki_inventoryis not callable, tell the user to add the server to their MCP client config and restart.
Pre-flight
Read CLAUDE.md. This is the authoritative schema — page
categories, frontmatter fields, link conventions, and operation
vocabulary. The user may have evolved it since wiki-init. Honor
the current state, not the defaults.
Flow
1. Snapshot
wiki_inventory()
One call returns every page's slug, frontmatter, body length, mtime,
etag, links_out, and computed links_in, plus the full parsed
log. This is the deterministic backbone for checks 3, 4, and 5.
2. Deterministic checks (from the snapshot alone)
These do not require reading page bodies.
Check 3 — Orphan pages. Any page with links_in == [] is an
orphan. summary pages are expected to be reached from the index
rather than from other pages, so they are not automatically orphans;
host Read index.md once and cross-check — flag a summary
page only if it has no index entry either. Entity, concept,
comparison, overview, and synthesis pages with zero inbound links
are reportable orphans regardless of index presence.
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.

wiki-lint is a skill published in the GitHub repository flsteven87/llm-wiki-mcp (1 stars, last pushed 5mo ago), licensed MIT. It adds 253 tokens to every session and 2,125 once invoked, about $0.0013 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 2026-08-31.
