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 D, and why

cosmobar scanned grade D with 3 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 3d 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.

cosmobar guided setup

Configure cosmobar by interviewing the user, then apply the result with one command. Do not hardcode the list of segments or themes — read them live from the binary so this stays correct as cosmobar gains new segments.

Steps

  1. Confirm the binary is installed. Run cosmobar --version.

    • If you get "command not found", tell the user to install it first: curl -sS https://raw.githubusercontent.com/oleksbard/cosmobar/main/install.sh | sh then stop and let them install.

  2. Discover what's available (dynamic — always run these, never assume):

    • cosmobar segments --json → array of segments, each with name, description, default_on, requires_git, pro_max_only.
    • cosmobar themes --json → array of theme names.

  3. Interview the user with the AskUserQuestion tool. Keep it short — group related choices:

    • Segments: present every segment returned by the JSON, using its description. Pre-select the ones where default_on is true. Mention that pro_max_only segments only show data on Pro/Max plans, and requires_git segments only appear inside a git repo. Let the user pick the set to show. The order they end up with is the left-to-right display order.
    • Theme: offer the names from the themes JSON (default coral).
    • Clock: 24h, 12h, or off.
    • Glyphs (optional): auto (default) or ascii — pick ascii only if their terminal can't render block characters like ▓░.
    • Style: lean (default), tick, or blocks (background pills). All styles are font-free — there is no Nerd Font / powerline option.
    • Caps — ask ONLY when the chosen style is blocks: soft (default) or square. For lean or tick, do not ask about caps at all. AskUserQuestion can't branch mid-batch, so put style in the first batch and send the caps question separately afterwards, only if style came back blocks.
    • Animation: on (default) or off. When on, a segment's value briefly scrambles through symbols and "decodes" into its new value whenever it changes — purely visual, width-stable. Offer off for users who want a completely static bar.
    • Rate-limit window (only if rate_limits is enabled): both (default), 5h, or 7d.
    • Cost rollup (only if cost is enabled): show today's cross-session spend (· $5.30 today) on the cost segment — today (default) to show, empty to hide.
    • Block cost (only if rate_limits is enabled): on (default) or off. When on, the 5-hour window shows its spend, e.g. 5h 31% $4.20 (2h30m left).

cosmobar is a skill published in the GitHub repository oleksbard/cosmobar (4 stars, last pushed 2mo ago), licensed MIT. It adds 68 tokens to every session and 1,266 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it D with 3 findings (downloads and executes remote code, reads agent configuration directories, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
