Arnav 77d74e0261 feat(config): XDG-style config location, with legacy fallback (#172) (#173)
* feat(config): resolve global config from an XDG-style location (#172)

The global config lived at ~/.obsidian-wiki, which isn't XDG-compliant.
It now resolves to $XDG_CONFIG_HOME/obsidian-wiki (default
~/.config/obsidian-wiki).

Existing installs are unaffected: if ~/.obsidian-wiki is present and the
XDG path is not, the legacy directory is used as-is. No migration is
required, and nothing moves on upgrade. Once the XDG path exists it wins,
so `mv ~/.obsidian-wiki ~/.config/obsidian-wiki` is all a migration takes.

Resolution is implemented identically in Python (cli.py), bash (setup.sh,
scripts/daily-update.sh, scripts/wiki-notify.sh), and the Config
Resolution Protocol that every skill defers to, so vault-scoped state and
named `config.<name>` profiles stay in one place.

* fix(config): stop setup from wiping user-added config keys

`write_config` rewrote the global config with only the three setup-managed
keys, so every `obsidian-wiki setup` — including the one a pip upgrade
prompts for — silently destroyed anything else in the file:
OBSIDIAN_LINK_FORMAT, QMD_WIKI_COLLECTION, WIKI_SKIP_PROJECTS, sync
settings, and comments.

Setup now owns only OBSIDIAN_VAULT_PATH, OBSIDIAN_WIKI_REPO and
OBSIDIAN_WIKI_VERSION, updating those in place and carrying every other
line over untouched. Duplicate definitions of a managed key collapse to
one.

Predates the XDG change (same behavior on main) but is fixed here because
this branch already touches config writing, and the XDG work makes
re-running setup more likely.

Also pins PYTHONPATH in both new test files so they exercise this
checkout rather than whatever obsidian_wiki happens to be installed.

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:

  1. Inline vault override (@name) — if the request contains an @<name> token, resolve <global config dir>/config.<name> directly, overriding the steps below. See "Targeting a specific vault" right after this list.
  2. 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.
  3. Global config — if no local .env is found, read <global config dir>/config.
  4. Prompt setup — if neither exists, tell the user to run wiki-setup.

The global config dir is XDG-style: $XDG_CONFIG_HOME/obsidian-wiki (default ~/.config/obsidian-wiki). Installs that already have a ~/.obsidian-wiki directory keep using it, so existing setups never break; new installs use the XDG path.

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 <global config dir>/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.

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 — 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.
