[READ] List active TrueNAS alerts with level, message, class, dismissed.

Args: target: TrueNAS target name from config; omit to use the default.

[READ] List ZFS datasets with id, name, type, pool, used/available.

Args: target: TrueNAS target name from config; omit to use the default.

[READ] Return detail for a single dataset by id (e.g. 'tank/data').

Args: dataset_id: TrueNAS dataset id (see dataset_list). target: TrueNAS target name from config.

[WRITE] Create a ZFS dataset. Non-destructive (creates new storage).

No undo descriptor — dataset deletion is intentionally out of scope.

Args: name: Full dataset path including the pool, e.g. 'tank/projects'. pool: Optional pool name for context/labelling. target: TrueNAS target name from config.

[READ] List physical disks with name, serial, model, size, pool.

Args: target: TrueNAS target name from config; omit to use the default.

[READ] Recent S.M.A.R.T. self-test results per disk (status/description).

Args: target: TrueNAS target name from config.

[READ] One-shot health summary: pools (capacity/health), alerts, services.

Call this first to triage a TrueNAS system before drilling into a specific pool, dataset, or service.

Args: target: TrueNAS target name from config; omit to use the default.

[READ] List ZFS pools with id, name, status, health, capacity.

Args: target: TrueNAS target name from config; omit to use the default.

[READ] Return detail for a single pool by id.

Args: pool_id: TrueNAS pool id (see pool_list). target: TrueNAS target name from config.

[READ] Health and scan/topology status of a single pool.

Args: pool_id: TrueNAS pool id. target: TrueNAS target name from config.

[READ] Current scrub scan state (function/state/percentage) for a pool.

Args: pool_id: TrueNAS pool id. target: TrueNAS target name from config.

[READ] Capacity summary per pool: size/allocated/free and used percent.

Args: target: TrueNAS target name from config.

[WRITE] Start a scrub (integrity check) on a pool. Non-destructive.

No undo descriptor (a scrub has no clean inverse beyond cancellation). Poll progress with scrub_status; do not re-issue.

Args: pool_name: ZFS pool name (e.g. 'tank'). target: TrueNAS target name from config.

[READ] List replication tasks with name, direction, transport, state.

Args: target: TrueNAS target name from config; omit to use the default.

[READ] List cloud-sync tasks with description, direction, path, state.

Args: target: TrueNAS target name from config.

[READ] List system services with name, state (RUNNING/STOPPED), enable.

Args: target: TrueNAS target name from config; omit to use the default.

[WRITE] Restart a system service (e.g. 'smb', 'nfs', 'ssh').

Captures the prior service state for the audit record; declares no undo (a restart is not cleanly reversible).

Args: service: TrueNAS service name (see service_list). target: TrueNAS target name from config.

[READ] List ZFS snapshots, optionally filtered to one dataset.

Args: dataset: Optional dataset path to filter (e.g. 'tank/data'). target: TrueNAS target name from config.

[WRITE] Create a ZFS snapshot 'dataset@name'. Inverse: snapshot_delete.

Args: dataset: Dataset path to snapshot (e.g. 'tank/data'). name: Snapshot name (e.g. 'manual-2026-06-28'). target: TrueNAS target name from config.

[WRITE] Delete a ZFS snapshot by id ('dataset@name'). IRREVERSIBLE.

Captures the snapshot's prior state for the audit record; declares no undo.

Args: snapshot_id: Full snapshot id 'dataset@name' (see snapshot_list). target: TrueNAS target name from config.

[READ] TrueNAS system summary: version, hostname, memory, cores, uptime.

Args: target: TrueNAS target name from config; omit to use the default.
