About the project

LLM Wiki is a system that uses AI agents to research sources, compile knowledge bases, organize project briefs, and answer questions from the resulting wiki. It is used to turn rough ideas and investigations into structured, reusable knowledge for agents, including Claude Code, Codex, and OpenCode. The catalogue entries are commands, hooks, skills, instructions, and a plugin that implement its workflow.

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.

Security

Grade A, and why

librarian 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 13d 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.

Your task

Resolve the wiki. Do NOT search the filesystem or read reference files — follow these steps:

  1. Read $HOME/.config/llm-wiki/config.json. If it has hub_path, expand leading ~ only (not tildes in com~apple~CloudDocs) and prefer that path; use resolved_path only as a fallback cache when the expanded hub_path is unavailable and resolved_path is initialized. If config has only resolved_path, use it. If the configured path can be statted but reading wikis.json or listing topics/ fails with Operation not permitted, stop and ask the user to grant Full Disk Access/iCloud Drive access to the launcher; do not fall back to ~/wiki or resolved_path. Do not write machine-specific resolved_path into shared configs.
  2. If no config → read $HOME/wiki/_index.md. If it exists → HUB = $HOME/wiki. If nothing found, ask the user where to create the wiki.
  3. Wiki location (first match): --local → .wiki/ in CWD; --wiki all → HUB with an ALL_TOPICS flag for step 5; --wiki <name> → HUB/wikis.json lookup with portable path resolution (<HUB>, ~, absolute, or HUB-relative); if the registry path is stale, fall back to HUB/topics/<name>; CWD has .wiki/ → use it; else → HUB.
  4. Read <wiki>/_index.md to verify. If missing → stop with "No wiki found. Run /wiki init first."
  5. Hub-level detection: Librarian operates on the wiki/ layer of a single topic wiki. The HUB has no wiki/ subdirectory — only wikis.json, _index.md, log.md, and topics/. If ALL_TOPICS is set from --wiki all, read registered topic wikis from HUB/wikis.json (excluding the synthetic hub entry) and iterate the scan against each topic wiki sequentially. If the resolved wiki is the HUB (detected by the presence of wikis.json and the absence of a wiki/ subdir) AND the user did not pass --wiki <name>, do NOT proceed with the scan against an empty topic surface. Instead, present a numbered list of registered topic wikis from HUB/wikis.json and ask the user to pick one. Re-resolve the wiki path with the selected name (HUB/topics/<name>/) and continue.

Read the librarian reference at skills/wiki-manager/references/librarian.md. Then execute the requested subcommand.

/wiki:librarian is the focused wiki-maintenance tool. It reviews the wiki/ layer only. If the user wants a broader trust inspection across outputs, provenance, and fresh research, direct them to /wiki:audit.

Inventory awareness: librarian reports may recommend inventory records for durable maintenance follow-ups such as stale article clusters, weak source chains, recurring refresh tasks, or watch items. Do not create records during a scan unless the user explicitly asks; include a compact sample shape when suggesting a larger maintenance backlog.

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.
