boxyard-cli

boxyard-cli is a skill for Claude Code, Codex from lukastk/boxyard. It costs 64 tokens per session (1,652 once invoked), scanned A, original, MIT.

A guide to Boxyard, a Python command-line tool for managing and syncing folders called boxes across local or remote storage.

In plain words
What is it for?
Use it to manage boxes, configure local or rclone-backed storage, check sync status, include or exclude files, group or rename boxes, and copy data.
Why use it?
It explains how to find, inspect, organise, and sync boxes while keeping generated data in the box it belongs to and controlling transfers with filters.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

boxyard-cli scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 24d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Boxyard CLI

Use this skill to use, not develop, Boxyard: managed folders with DATA, metadata, sync config, groups, and local/rclone storage. All bundled paths below resolve from this skill directory; no source checkout is required.

Authority and safety

  • Ask before modifying local or remote state. This includes init, new, sync, multi-sync, sync-missing-meta, include, exclude, relocate, delete, rename, sync-name, group/parent edits, create-user-symlinks, copy, force-push, claim, release, discard-local, and non-dry-run convert. Examples are not authorization. Read-only queries, --help, doctor, and convert --dry-run may run without confirmation.
  • Never create ad-hoc folders/clones/worktrees in ~/dev. Find the existing box or use boxyard new with approval; put non-box scratch outside managed roots. Keep generated data, even large outputs, inside its related box. Use sync excludes, not sibling folders, to avoid uploading it.
  • Resolve identity and placement, don't guess. Both timestamp format and subid length are configurable; index_name is {box_id}__{name}. Use which/path: DATA may be in any checkout root, not just user_boxes_path (default). An unavailable root never falls back to default. Placement is machine-local, never synced in boxmeta.toml; remote storage and local placement are independent.
  • Resolve ownership, never bypass it. DATA/CONF pushes compare write_owner with configured machine_name, never a hostname. No owner means unrestricted. new claims by default (--no-claim for work elsewhere); include --read-only suppresses the claim nudge. Refusal also protects force-push, remote/both rename, and deletion. With approval, claim --steal keeps this machine's work; discard-local replaces it from remote and keeps overwritten work in backups.
  • Destructive traps: new --from PATH MOVES unless --copy; exclude syncs first then removes local DATA (--skip-sync skips that protection). delete tombstones the id fleet-wide: never delete a stale duplicate name to clean registrations. sync --sync-setting replace|force, copy --overwrite, and force-push --force can overwrite data. Read the relevant reference first.
  • Backups aren't garbage: orphan findings may be intentional discard-local keepsakes. Never auto-delete them or infer disposability from unclaimed ULIDs.
  • Excludes replace, not extend. A box's conf/.rclone_exclude replaces the default list entirely: copy the default contents before adding rules, or risk syncing .venv/, node_modules/, etc. .rclone_include and .rclone_filters are currently refused; use .rclone_exclude alone. CONF syncs before DATA. Default-exclude edits invalidate DATA baselines fleet-wide; batch needed edits.
  • Conversion is explicit: policy edits never reformat existing boxes; only convert does, verifying a byte-identical restore before removing the old copy. Read the storage reference and ~/.config/myagent/reference/box-storage.md before recommending/changing plain vs restic. Rig default is plain; package default for rclone is restic (local is plain). Every participating machine needs Boxyard >=0.7.0, restic and the password before using restic boxes.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
