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

cubox 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 337 lines — stays where its author put it; the contents beside it link to each section on GitHub.

cubox-cli

Manage Cubox bookmarks via the cubox-cli command-line tool.

Authentication and Secrets

If any command fails with "API Key does not exist", never ask the user to paste their API token into chat and never construct commands that embed a literal token in argv. Use one of these safe paths:

  1. Interactive login: ask the user to run cubox-cli auth login in their own terminal.
  2. Agent / CI without persistence: ask the user to set CUBOX_SERVER and CUBOX_TOKEN in their shell before invoking the CLI.
  3. Non-interactive persisted login: ask the user to pipe the token via stdin: printf '%s' "$TOKEN" | cubox-cli auth login --server cubox.pro --token-stdin.

Forbidden: asking for tokens in chat, suggesting cubox-cli auth login --token <literal-token>, committing credentials, or copying tokens into screenshots or shared notes. If a token may have leaked, tell the user to rotate it from the Cubox extensions page.

Commands

Most query commands and batch mutation commands output compact JSON by default. Add -o pretty for indented JSON, -o text for human-readable output.

Known success-output exceptions: save, update, and auth subcommands currently print plain text even when -o json is selected. Do not assume every successful command stdout is parseable JSON.

List Folders

cubox-cli folder list

Returns: [{ "id", "nested_name", "name", "parent_id", "uncategorized" }]

List Tags

cubox-cli tag list

Returns: [{ "id", "nested_name", "name", "parent_id" }]

Manage Tags (rename / delete / merge)

These mutate tags directly. They take tag IDs (not names) — call tag list first if you only have a name.

# Rename a tag — only the leaf segment changes; nested children stay attached
cubox-cli tag update --id TAG_ID --new-name NEW_NAME

# Batch delete tags — cards keep their other tags; only the tag-card link is removed
cubox-cli tag delete --id TAG_ID[,ID2,...]

# Merge source tags into a target tag — cards are re-tagged onto the target,
# then the source tags are deleted
cubox-cli tag merge --source SRC_ID[,ID2,...] --target TARGET_ID

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
