Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00059 | $0.01282 |
| Opus 5 | $0.00030 | $0.00641 |
| Sonnet 5 | $0.00012 | $0.00256 |
| Haiku 4.5 | $0.00006 | $0.00128 |
Grade A, and why
computer-use 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 yesterday.
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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Computer Use
Use the bundled Python script to inspect and operate application windows on the machine running the vBot server. This is a script-backed prototype, not a built-in Tool. On a remote Pi-server plus Windows Desktop Client setup it controls the Pi desktop, not the user's Windows Desktop Client.
The wrapper uses cua-driver's one-shot CLI transport. It requests background delivery by default, but actual behavior and supported applications depend on the host platform and installed driver version.
Script contract
- Run
python {baseDir}/scripts/computer_use.py --session <session> doctorbefore the first desktop action in a task. - Choose a unique lowercase session name containing only letters, digits, hyphens, or underscores. Reuse it for the complete task and call
startonce before inspection. - Treat stdout JSON as data. Exit code zero with
"ok": truemeans the operation completed. A nonzero exit or"ok": falsemeans it did not. - The script never installs or upgrades
cua-driver. Report a missing or incompatible driver and ask before installing anything. - Captures and oversized accessibility data are written below
tmp/computer-use/<session>/in the effective cwd. Load screenshot paths with vBot'sreadTool. - Element actions (
click/scrollwith--element) accept an element index or anelement_token(e.g.s00000001:12) from a capture. An index resolves against the session's latest capture of the samepid/window_id; capture the target window first, and re-capture when the UI changed since your last capture. - Mutating commands require the explicit
--applyflag. Without it, the script returns a dry-run description and performs no input action. - Applied actions report the driver's
delivery,effect, androutemetadata.effect: "unverifiable"is normal — it means the driver sent the input but could not confirm the outcome, so verify by re-capturing. - The wrapper invokes
cua-driverwithout a shell and removes credential-like environment variables from its child environment.
What ships with it
1 file 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.
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.

computer-use is a skill published in the GitHub repository Vironnimo/vbot (1 stars, last pushed 2d ago), licensed Apache-2.0. It adds 59 tokens to every session and 1,282 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
