# Obsidian Wiki — Agent Context
A **skill-based framework** for building and maintaining an Obsidian knowledge base. No scripts or dependencies — everything is markdown instructions that you execute directly.
## README Translation Parity
`README.md` and `README_TW.md` are one documentation surface. Keep headings, examples, links, and user-facing behavior aligned between the two translations. The check is advisory and never blocks a PR: the `readme-translation-drift` CI job only reports drift. Run `python tools/check_readme_sync.py` to list commits that changed `README.md` without a later `README_TW.md` update, along with the pending English diff — then translate and backfill those changes into `README_TW.md`. Reviewers assess translation quality.
## Configuration
Resolve config using the Config Resolution Protocol in `llm-wiki/SKILL.md`:
0. **Inline vault override (`@name`)** — if the request contains an `@<name>` token, resolve `~/.obsidian-wiki/config.<name>` directly, overriding the steps below. See "Targeting a specific vault" right after this list.
1. **Walk up from CWD** — look for a `.env` file in the current directory, then each parent, up to `$HOME`. Stop at the first `.env` that contains `OBSIDIAN_VAULT_PATH`.
2. **Global config** — if no local `.env` is found, read `~/.obsidian-wiki/config`.
3. **Prompt setup** — if neither exists, tell the user to run `wiki-setup`.
The resolved config sets `OBSIDIAN_VAULT_PATH` (where the wiki lives). It may also set `OBSIDIAN_WIKI_REPO` (where this repo is cloned) and other optional variables.
### Targeting a specific vault
You can maintain multiple vaults (each a `~/.obsidian-wiki/config.<name>` file managed by `wiki-switch`) and reach any of them from any directory:
- **`@name` (per-invocation override)** — prefix or mention `@<name>` anywhere in a request to route that one command to that vault, e.g. `@work save this` or `wiki-query @personal what do I know about X`. It overrides the CWD `.env` and the active symlink **for that invocation only** — it does **not** flip your default vault. If `config.<name>` doesn't exist, the skill reports it and lists available vaults; do **not** silently fall back to the default. The `@name` is stripped before the rest of the request is used as content.
- **`/wiki-switch <name>` (persistent default)** — re-points the active symlink so all future requests use that vault. This is your default "brain" vault; use `@name` to dip into the other one without switching.
**After reading config, always read `$OBSIDIAN_VAULT_PATH/AGENTS.md` if it exists.** It contains owner-specific conventions (domain vocabulary, ingest preferences, writing style, project scoping) that override framework defaults for all skills. Apply it for the duration of the session.
## Vault Structure
```
$OBSIDIAN_VAULT_PATH/

├── log.md # Chronological activity log (ingests, updates, lints)
├── hot.md # Session hot cache — ~500-word semantic snapshot of recent activity
├── .manifest.json # Tracks every ingested source: path, timestamps, pages produced
├── _meta/

├── _insights.md # Graph analysis output (hubs, bridges, dead ends)
├── _raw/ # Staging area — drop rough notes here, next ingest promotes them
├── _readouts/ # Derived narrative readouts saved by wiki-narrate — not knowledge pages
├── concepts/ # Abstract ideas, patterns, mental models
├── entities/ # Concrete things — people, tools, libraries, companies
├── skills/ # How-to knowledge, techniques, procedures

```
Every wiki page has required frontmatter: `title`, `category`, `tags`, `sources`, `created`, `updated`. Pages connect via internal links — `[[wikilinks]]` by default, or standard Markdown links when `OBSIDIAN_LINK_FORMAT=markdown` is set in config.

+ ### Session history: ingest vs. retrieve
+
+ Three skills read agent session caches, and they are not interchangeable:
+
+ - `wiki-history-ingest` (and its per-agent variants) **ingests** — distils sessions into permanent vault pages.
+ - `wiki-agent` **ingests a slice** — finds sessions about one topic in another agent's history and pulls them into the vault.
+ - `session-brain` / `session-search` **retrieve** — build a topic graph over the raw sessions and find or load one. They write a sidecar at `~/.claude/session-brain/` and never touch the vault.
+
+ If the user wants knowledge preserved, ingest. If they want to find the session where something happened, retrieve.
+
## Cross-Project Usage
The main use case: you're working in some other project and want to sync knowledge into your wiki, query it, or compile bounded context. Three portable skills handle this — `wiki-update`, `wiki-query`, and `wiki-context-pack`. They work from any directory.
### wiki-update (write to wiki)
1. Resolve config using the Config Resolution Protocol to get `OBSIDIAN_VAULT_PATH`
2. Scan the current project: README, source structure, git log, package metadata
3. Distill what's worth remembering (architecture decisions, patterns, trade-offs — not code listings)
4. Write to `$VAULT/projects/<project-name>.md`, cross-linking to concept/entity pages as needed
5. Update `.manifest.json`, `index.md`, and `log.md`
On repeat runs, it checks `last_commit_synced` in `.manifest.json` and only processes the delta via `git log <last_commit>..HEAD`.
### wiki-query (read from wiki)
1. Resolve config using the Config Resolution Protocol to get `OBSIDIAN_VAULT_PATH`
2. Scan titles, tags, and `summary:` frontmatter fields first (cheap pass)
3. Only open page bodies when the index pass can't answer
4. Return a synthesized answer with `[[wikilink]]` citations
### wiki-context-pack (read-only context)
1. Resolve the target vault and read its owner `AGENTS.md`
2. Rank existing notes without requiring schema migration
3. Compile summaries and selected excerpts within a hard token budget
4. Return a provenance-rich pack; never write it back to the vault
## Visibility Tags (optional)
Pages can carry a `visibility/` tag to mark their intended reach. **This is entirely optional** — untagged pages behave exactly as they always have (visible everywhere). The system stays single-vault, single source of truth.
| Tag | Meaning |
|---|---|
| *(no tag)* | Same as `visibility/public` — visible in all modes |
| `visibility/public` | Explicitly public — visible in all modes |
| `visibility/internal` | Team-only — excluded when querying in filtered mode |
| `visibility/pii` | Sensitive data — excluded when querying in filtered mode |
**Filtered mode** is opt-in, triggered by phrases like "public only", "user-facing answer", "no internal content", or "as a user would see it" in a query. Default mode shows everything.
`visibility/` tags are **system tags** — they don't count toward the 5-tag limit and are listed separately from domain/type tags in the taxonomy.
See `wiki-query` and `wiki-export` skills for how the filter is applied.
## Core Principles
- **Compile, don't retrieve.** The wiki is pre-compiled knowledge. Update existing pages — don't append or duplicate.
- **Track everything.** Update `.manifest.json` after ingesting, `index.md`, `log.md`, and `hot.md` after any write operation.
- **Connect with `[[wikilinks]]`.** Every page should link to related pages. This is what makes it a knowledge graph, not a folder of files.
- **Frontmatter is required.** Every wiki page needs: `title`, `category`, `tags`, `sources`, `created`, `updated`.
- **Single source of truth.** Visibility tags shape how content is surfaced — they don't duplicate or separate it.
- **Keep context warm.** `hot.md` is a ~500-word semantic snapshot of recent activity. Every write skill updates it so the next session can pick up where the last one left off without crawling the full vault.
## Architecture Reference
For the full pattern (three-layer architecture, page templates, project org), read `.skills/llm-wiki/SKILL.md`.
+
+ Human-facing documentation lives in `docs/` — `installation.md`, `agents.md`, `skills.md`, `cli.md`, `configuration.md`, `architecture.md`, `session-brain.md`, `contributing.md`. `README.md` is a landing page only; when you add a skill, CLI command, or config variable, update the matching `docs/` page rather than the README.
The vault format is structurally conformant with the [Open Knowledge Format (OKF) v0.1](https://github.com/GoogleCloudPlatform/knowledge-catalog/blob/main/okf/SPEC.md) — markdown files with YAML frontmatter, category subfolders, reserved `index.md`/`log.md`. `wiki-export` (OKF mode) and `wiki-import` are the bridge: they translate between our native frontmatter (`title`/`category`/`tags`/`sources`/`created`/`updated` + `summary`) and OKF (`type`/`title`/`description`/`resource`/`tags`/`timestamp`), making vaults exchangeable with any OKF tool. The OKF round-trip is lossless; the `graph.json` round-trip is not.
