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 5.1 | $0.00028 | $0.00301 |
| Opus 5.5 | $0.00011 | $0.00120 |
| Sonnet 5.5 | $0.00006 | $0.00060 |
| Haiku 4.5 | $0.00003 | $0.00030 |
Grade A, and why
vocello-macos-ui 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 2d 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.
What it actually says
macOS UI validation
Arguments: $ARGUMENTS
Read docs/reference/native-engineering.md, docs/reference/testing-runbook.md and relevant Axiom
macOS/testing guidance. Choose the smallest lane from scripts/ui_test.sh help; compile-only work
uses scripts/build_ui_test_bundles.sh macos.
Join/stop workers and commit source before source-bound UI/performance evidence. Use the host lock,
load/memory checks and installed assets; if tracking is unavailable explicitly declare lead-only
after joining all workers. Run scripts/ui_test.sh macos <lane> <options> from the repository root.
Repository XCUITest is the only automated native UI evidence; use genuine controls and stable
identifiers. Computer use covers what XCUITest cannot, between lanes and never while one runs
(/vocello-ui-autonomy). After the lane, review <run>/screenshots/index.json.
Keep the run ID, raw log, result bundle, ledgers and failed evidence. Triage the finished directory
with scripts/dev.sh triage <run-directory> --json or the read-only vocello-xcresult-triage agent;
report limits. Reruns require a reason and new ID.
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.

vocello-macos-ui is a skill published in the GitHub repository PowerBeef/Vocello (386 stars, last pushed today), licensed MIT. It adds 28 tokens to every session and 301 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-10-11.

critique
Adversarial design critique of the current work. Render it, look at it, and argue for rejection. Run after the gates are green, never instead of them.
verify-ui-change-in-cloud
Verifies user-facing Warp client changes by spawning a cloud agent with computer use to test Warp. Use only when the user explicitly requested computer-use verification or accepted an offer to run it, and ONLY in non-sandboxed environments and local environments. Triggers a cloud agent that runs the test-warp-ui skill.
test-warp-ui
Guides testing Warp UI features and changes using the computer use tool. Use this skill only when computer-use testing was requested (explicit request or accepted offer) and the computeruse tool is available to the agent. Covers launching Warp and verifying UI behavior.
