Route by vault methodology

This skill returns filing suggestions. It does not write knowledge pages or
move existing notes. If .vault-meta/mode.json is absent, use generic. If
the file exists but is invalid, fail closed and repair it through a reviewed
configuration operation before suggesting routes; never silently substitute
Generic for corrupt user configuration.

Resolve the installed product root from this skill's own location, not from the
vault or current working directory:

PRODUCT_ROOT=/absolute/path/to/installed/claude-obsidian
CORE="$PRODUCT_ROOT/scripts/claude-obsidian.py"
MODE_HELPER="$PRODUCT_ROOT/scripts/wiki-mode.py"
test -f "$CORE" && test -f "$MODE_HELPER"

Read and route safely

Always select the vault explicitly:

python3 "$MODE_HELPER" --vault "$VAULT" get
python3 "$MODE_HELPER" --vault "$VAULT" config
python3 "$MODE_HELPER" --vault "$VAULT" route concept "Concept name"
python3 "$MODE_HELPER" --vault "$VAULT" route source "Source title"

The helper validates the selected vault, confines paths, sanitizes names, and
prints a suggestion only. A calling skill may override the suggestion when the
user supplies a more specific project, area, MOC, or parent note, but it must
still apply its eventual writes through one operation transaction.

Mode	Routing intent
generic	Type-based folders such as sources, entities, concepts, and sessions.
lyt	Atomic notes under wiki/notes/, connected through MOCs.
para	Projects, Areas, Resources, or Archives chosen by actionability.
zettelkasten	Flat atomic notes with time-sortable, collision-resistant identifiers and explicit links.

Use the templates under templates/ as structural guidance, not authority to
overwrite user conventions.

Change mode

A mode change is one configuration operation, dry-run first:

1. Read the current .vault-meta/mode.json, or start from the helper's default
   config when it is absent.

2. Validate the requested mode as exactly generic, lyt, para, or
   zettelkasten. Preserve the other mode-specific settings.

3. Choose and retain a pinned UTC timestamp and operation ID for both commands.

4. Preview the canonical configuration transaction; the command records the
   current target hash and limits the write to .vault-meta/mode.json:

   python3 "$CORE" mode set "$MODE" --vault "$VAULT" \
     --generated-at "$GENERATED_AT" --operation-id "$OPERATION_ID"

5. Show the old mode, new mode, exact changed path, and complete preview. Copy
   its approved_plan_sha256 only after review.

6. Apply by regenerating that exact vault-bound plan:

   python3 "$CORE" mode set "$MODE" --vault "$VAULT" \
     --generated-at "$GENERATED_AT" --operation-id "$OPERATION_ID" \
     --approved-plan-sha256 "$APPROVAL_SHA256" --apply

Follow the operation transaction contract.
Do not use scripts/wiki-mode.py's legacy direct-write set action or a setup
script to bypass this workflow.

Changing mode affects routing for future operations only. Never bulk-create
folders, move notes, rewrite wikilinks, or migrate existing pages as a side
effect. If migration is later requested, plan and review it as a distinct
operation with its own hashes and transaction.

Checkpoint

Observe the user's current structure, think about how they retrieve and act on
notes, verify a few proposed routes before changing configuration, and grow by
revisiting the mode only when real filing friction appears.
