What is wiki-maintain?

A maintenance tool for a project wiki, a collection of linked knowledge pages. It checks links and page metadata, finds duplicates and gaps, and reviews page confidence and freshness.

Use it to lint pages, merge confirmed near-duplicates, find missing coverage, update confidence levels, and flag stale content.

It helps keep a growing wiki accurate, connected, and up to date instead of leaving broken links, repeated pages, or missing topics unnoticed.

Install

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.

Any agent

npx skills add Oshayr/LLM-Wiki --skill maintain

Clone the repo

git clone --depth 1 https://github.com/Oshayr/LLM-Wiki

Made for: Claude Code.

Or install llm-wiki, the plugin that ships this one along with the rest of its 5 skills, 10 agents.

Token cost

What it costs to keep this loaded

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	$0.00061	$0.00900
Opus 5.5	$0.00024	$0.00360
Sonnet 5.5	$0.00012	$0.00180
Haiku 4.5	$0.00006	$0.00090

Security

Grade A, and why

wiki-maintain 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.

Wiki Maintain

Comprehensive wiki maintenance: lint, deduplicate, upgrade, and analyze.

Resolve .wiki/ from plugin install scope. If not found, say "No wiki found."

Arguments

/wiki-maintain — run full maintenance (all steps below)
/wiki-maintain lint — only fix broken links, missing frontmatter, orphans
/wiki-maintain dedup — only find and merge near-duplicate pages
/wiki-maintain gaps — only analyze knowledge gaps and missing coverage

Full Maintenance Steps

1. Lint

Launch wiki-auditor agent to:

Find [[wiki-links]] that point to non-existent pages — list for user
Fix missing frontmatter fields (add defaults)
Find orphan pages (no incoming links) — suggest connections
Remove dead index entries
Fix stale updated: dates on pages that were modified but not date-bumped

2. Deduplicate

Find pages with >60% slug token overlap (Jaccard similarity on slug words split by -):

Report pairs for review
For confirmed duplicates: auto-merge into one page, update all backlinks, add redirect note to absorbed page

3. Confidence Upgrade

Pages with 3+ independent sources in frontmatter get upgraded:

low → medium (if 2+ sources)
medium → high (if 3+ corroborating sources)
Run fact-checker agent on high-confidence pages to verify claims against external sources
Write the reason in log.md

4. Stale Detection (Freshness Tiers)

Pages are evaluated against an intelligent freshness system — not a flat threshold. Each page has a TTL based on its content type:

Tier	TTL	Examples
`live`	15 min	stock prices, live scores, server status, deployment state
`breaking`	1-6 hours	breaking news, incident updates, release announcements
`current`	1-3 days	news articles, current events, trending topics
`fast`	1-4 weeks	AI/LLM/MCP, API changes, model benchmarks
`moderate`	1-3 months	software versions, frameworks, libraries, tools
`standard`	6 months	general knowledge, how-to guides (default)
`academic`	1 year	research papers, studies, formal publications
`evergreen`	5 years	history, biographies, foundational concepts, laws, theorems
`permanent`	never	personal notes, ideas, memories, journal entries

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-maintain is a skill published in the GitHub repository Oshayr/LLM-Wiki (50 stars, last pushed 6mo ago), licensed MIT. It adds 61 tokens to every session and 900 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.
