Obsidian CLI read transport

Use this skill only to detect transport and read or search a selected vault.
The official executable is obsidian; binary presence alone does not prove it
is usable.

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
DETECT_TRANSPORT="$PRODUCT_ROOT/scripts/detect-transport.sh"
test -f "$DETECT_TRANSPORT"

Detect safely

Probe without persisting host state:

bash "$DETECT_TRANSPORT" --peek --vault "$VAULT"

Trust available.cli.usable, not merely present or exit status. A supported
CLI can still be unavailable because the Obsidian app is not running, command
line access is disabled, or its response is an error. Use filesystem reads as
the portable fallback.

Persist a refreshed .vault-meta/transport.json only when the user or setup
workflow asks for a transport snapshot:

bash "$DETECT_TRANSPORT" --force --vault "$VAULT"

That file is derived runtime configuration, not knowledge content. Preserve a
valid manual_override recorded by the detector.

Read and search

Run official CLI commands from the selected vault so Obsidian resolves the
correct workspace. Confirm supported syntax with the installed CLI before
relying on optional commands. Typical read-only forms are:

(cd "$VAULT" && obsidian read path="$NOTE")
(cd "$VAULT" && obsidian search query="$QUERY")

Use read-only commands for backlinks, tags, or Bases results only when the
detector reports the CLI ready. Otherwise read files under $VAULT directly
and use rg for search. Reject absolute note arguments, traversal, symlinks, or
resolved paths outside the selected vault.

Mutation boundary

Do not use CLI create, write, append, property-set, daily-append, move, rename,
or delete commands. Do not replace those commands with direct filesystem
writes. Any knowledge or configuration change must be expressed as one
reviewed transaction through the portable core; see
operation transactions.

Transport choice never changes mutation semantics. The CLI is an optional read
surface, not a lock manager, transaction engine, or Git checkpoint mechanism.

Checkpoint

Observe actual capability, think about the least complex read transport, verify
that every resolved path stays in the vault, and accept filesystem fallback
when the CLI is not ready.
