Mimir — a living wiki in Obsidian, powered by Hermes

The idea

A second brain that tends itself. You hand it whatever you want to keep — an article, a document, a note, an idea caught in passing — and rather than letting it pile up in a heap, Mimir digests it: it links it, shapes it, files it away. A living body of knowledge that grows and weaves itself over time.

The goal isn't to hoard, but to understand: turning a stream of scattered sources into clear, navigable, connected knowledge.

Mimir bridges the two, continuously — without ever copying a raw source into the wiki: it understands it first, then rephrases it.

How it works

Under the hood, Mimir is a suite of 8 skills (agentskills.io) orchestrated by the Hermes agent. A source goes in, a connected wiki comes out:

Source (PDF · EPUB · URL)
   │
   ├─ wiki-extract       → stores the raw source, faithful and immutable
   ├─ wiki-ingest        → digests it into wiki articles, one notion per page
   ├─ wiki-batch-produce → same, in deterministic batch (web only)
   ├─ wiki-reading-grid  → derives an ordered reading grid from it
   ├─ wiki-index         → rebuilds the INDEX and checks the links
   └─ wiki-sync          → syncs everything to the Obsidian vault

A seventh skill, wiki-init, sets the stage on first use: it creates the second brain's folder structure and bootstraps the sync.

An eighth skill, wiki-research, lives in a different lane: for a deep-dive on a text subject, the agent picks web sources, has them clipped automatically (it reuses wiki-extract), then writes a synthesis report in reading-grids/<subject>.md. Source picking and writing are semantic; the clip and the scaffold stay deterministic.

Installation

Prerequisite: Hermes Agent installed.

hermes profile install https://github.com/vivian-maes/mimir.git
hermes update     # seeds the base skills: without it, the profile only has the wiki-*

On first launch, on a Hermes that isn't configured yet, the “hermes setup” assistant configures the provider, the terminal and — optionally — messaging:

hermes -p mimir chat

Finally, drop wiki.config.json into ~/.hermes/profiles/mimir/ (auto-discovered), then check with hermes profile info mimir.

Updating (profile already installed): hermes profile update mimir — the command takes the profile name, not the git URL.

First use

On an empty vault, ask Mimir to “initialise the wiki” (the wiki-init skill): it creates the folder structure (_inbox/, raw/, wiki/, reading-grids/), a quick-start guide, a starter INDEX.md, then bootstraps the first sync. After that, dropping a source into _inbox/ kicks off the pipeline.

A note on language

Mimir was born in French. I'm a French speaker (Belgian, mind you — not French, let's not start anything), and it began as a personal project I'm sharing in the language I thought it up in.

This English version is a fresh translation — if a sentence reads a little sideways, that's on me. Full multilingual support is for later: somewhere between “soon” and “when the fries are done”. 🍟

It's young, it's being debugged, it'll move — and any feedback is welcome: a bug you hit, an idea, a use case nobody thought of. Open an issue or share your experience.
