obsidian-wiki is a framework that helps AI agents build and maintain an interconnected knowledge base from text-based material in an Obsidian vault. It is for people who want their agents to remember discoveries, connect related information, and answer questions with wiki-link citations. Catalogue add-ons provide the agent skills, instructions, agents, and configuration used to create and maintain these wikis.
Getting it into your agent
There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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 | $0.00105 | $0.02070 |
| Opus 5 | $0.00053 | $0.01035 |
| Sonnet 5 | $0.00021 | $0.00414 |
| Haiku 4.5 | $0.00011 | $0.00207 |
Grade A, and why
wiki-rebuild 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 11d 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 — 213 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Wiki Rebuild — Archive, Rebuild, Restore
You are performing a destructive operation on the wiki. Always archive first, always confirm with the user before proceeding.
Before You Start
- Resolve config — follow the Config Resolution Protocol in
llm-wiki/SKILL.md(inline@nameoverride → walk up CWD for.env→ global config → prompt setup). This givesOBSIDIAN_VAULT_PATHand optional QMD settings such asQMD_WIKI_COLLECTION - Read
.manifest.jsonto understand current state - Confirm the user's intent. This skill supports three modes:
- Archive only — snapshot current wiki, no rebuild
- Archive + Rebuild — snapshot, then reprocess all sources from scratch
- Restore — bring back a previous archive
The Archive System
Archives live at $OBSIDIAN_VAULT_PATH/_archives/. Each archive is a timestamped directory containing a full copy of the wiki state at that point.

Mode 1: Archive Only
When the user wants to snapshot the current state without rebuilding.
Steps:
- Create archive directory:
_archives/YYYY-MM-DDTHH-MM-SSZ/ - Copy all category directories,
index.md,log.md,.manifest.json, andprojects/into the archive - Write
archive-meta.jsonwith reason"snapshot" - Append to
log.md:- [TIMESTAMP] ARCHIVE reason="snapshot" pages=87 destination="_archives/2026-04-06T10-30-00Z" - Optionally refresh QMD if
log.mdis indexed andQMD_WIKI_COLLECTIONis configured (see "QMD Refresh After Live Wiki Changes"). - Report: "Archived 87 pages. Current wiki is untouched."
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-rebuild is a skill published in the GitHub repository Ar9av/obsidian-wiki (3,381 stars, last pushed yesterday), licensed MIT. It adds 105 tokens to every session and 2,070 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 2026-08-30.

knowledge-base-management
A lifecycle system for managing an Obsidian knowledge base, which is a folder of linked notes. It organizes raw material, AI-maintained wiki pages, and generated views into separate layers.
llm-wiki
Maintain a personal team knowledge base using the LLM Wiki pattern — incremental ingest, query, and lint operations on a layered wiki architecture.
llm-wiki
Build and maintain a persistent, interlinked Obsidian-compatible markdown wiki using Karpathy's LLM Wiki pattern. Extension-backed with auto-generated metadata, guardrails, and 14 custom tools (+3 opt-in agent-trajectory tools).
link-memory
Use after important user-approved decisions, when durable context should be proposed or reviewed, and for explicit Link memory lifecycle work: remember, recall, review, update, archive, restore, forget, or explain local memories through the CLI without requiring MCP.
link-retrieve
Use before answering work that may depend on user memory, project history, source-backed notes, or prior decisions; retrieve compact Link context through the CLI without loading the whole wiki or requiring MCP.
link-ingest
Use when raw files are present, source pages look stale, or a user asks to ingest notes into Link; refresh source-backed wiki pages, propose memories, and validate updates through the CLI without MCP.
