SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00069 | $0.01444 |
| Opus 5 | $0.00034 | $0.00722 |
| Sonnet 5 | $0.00014 | $0.00289 |
| Haiku 4.5 | $0.00007 | $0.00144 |
Grade A, and why
run-desktop scanned grade A with 1 finding 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 7d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl -X POST http://127.0.0.1:19280/status -H 'Content-Type: application/json' \ How it starts
The opening of the file, as written. The whole thing — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.
VibeMon is a tray-only Electron app: pnpm start shows no window, because the
character window is created on demand by a POST /status to its local HTTP
server. For agent use, drive it through
.claude/skills/run-desktop/driver.mjs — a zero-dependency driver that speaks
the Chrome DevTools Protocol over Node's built-in WebSocket (Node >= 22, no
npm install, no tmux).
The driver always launches with an isolated --user-data-dir, so a run never
touches the developer's real settings in ~/Library/Application Support/vibemon.
Run (agent path)
One shot: pass the commands as arguments. They run in order, the app is closed at the end, and the exit code is non-zero if any command failed.
node .claude/skills/run-desktop/driver.mjs \
"launch 3d" "lock codex" "status working" "engine" "ss codex-3d" "logs"
Then open the PNG and look at it. Screenshots land in /tmp/vibemon-shots/
(override with SCREENSHOT_DIR).
Run it with no arguments for an interactive driver> REPL instead (same
commands, quit to exit).
The real app must not be running — it owns port 19280, and launch fails fast
with a clear error if the port is taken.
Commands
| command | what it does |
|---|---|
launch [2d|3d] |
seed the render mode, boot the app, wait for its HTTP server |
status <state> [character] [project] |
POST /status → creates/updates the character window, waits for it |
lock <character|auto> |
POST /character-lock — pins the character against other bridges |
focus |
what the window is actually showing (focused project / character / state) |
ss [name] |
screenshot over an opaque backdrop, prints focus alongside |
ss-raw [name] |
screenshot the true transparent frame |
engine |
which engine booted: vibemon-canvas (2D) vs vibemon-canvas-3d (WebGL) |
page <character|bubble> |
retarget commands at the character window or the speech bubble |
windows |
list open windows |
eval <js> / text [sel] |
evaluate in the page / dump innerText |
wait <ms> |
pause the sequence (e.g. to let an animation settle) |
logs |
renderer console, uncaught errors, CSP violations, and main-process output since launch |
quit |
close the app (implicit at the end of a one-shot run) |
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.
- 7d ago First seen · 110 lines · 69 tokens per session scan A 25714a56fb87
run-desktop is a skill published in the GitHub repository opspresso/vibemon-app (23 stars, last pushed 13d ago), licensed MIT. It adds 69 tokens to every session and 1,444 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
