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.

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 | $0.00050 | $0.01977 |
| Opus 5 | $0.00025 | $0.00988 |
| Sonnet 5 | $0.00010 | $0.00395 |
| Haiku 4.5 | $0.00005 | $0.00198 |
Grade A, and why
screen-companion 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 8d 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 — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Screen Companion
Sutando is already capable of watching your screen + voice-chatting in real time (vision push-mode from PR #735 + bodhi VoiceSession). The gap this skill closes: Sutando doesn't know what you're trying to do. Every session you have to re-narrate intent ("I'm reading a paper, ask about figures"; "I'm debugging, suggest hypotheses").
This skill ships pre-baked interaction-pattern configs — each one encodes a purpose, the right system-prompt overlay, the right tool subset, and the right vision cadence. Owner activates a config by name; the skill handles the rest.
When to Use
- "Read this paper with me" — paper-reading mode (PDF / arXiv / blog).
- "Debug this with me" — stack-trace + IDE pair-debug.
- "Review this PR with me" — GitHub PR diff walk-through.
- Or any other use-case that has a config in
configs/.
NOT for: silent screen-watching (use the voice agent directly), one-shot questions about a screenshot (use the look_at_screen inline tool).
Architecture
configs/<name>.yaml # the interaction pattern, declarative
↓
scripts/activate.ts # entry: --config <name> [--goal "..."]
↓ loads config, builds:
↓
voice-agent's VoiceSession # gets a system-prompt overlay + tool subset
↓ # + vision_mode + cadence_ms config
Push-mode vision frames flow # at the configured cadence
↓
Owner asks questions in voice # answers grounded in what's on screen
The skill itself is small — most of the value lives in the configs. New use case = drop a YAML into configs/. No code change required.
Configs ship with v0
| Config | Activation | Vision mode | Shape |
|---|---|---|---|
guided-setup |
--config guided-setup --goal "..." or "guide me through this" |
push, 700ms | proactive + goal-directed (Sutando narrates next steps for a configuration task) |
v0 demo angle: "Sutando helps you set up something you've never done before" (e.g., a Discord dev portal bot config). User shares screen, names the goal at activation, Sutando narrates the next concrete step in real time. More visceral demo than paper-reading; matches a near-universal user pain (everybody fights some dev portal once a quarter).
What ships with it
8 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.
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.

screen-companion is a skill published in the GitHub repository sonichi/sutando (393 stars, last pushed yesterday), licensed MIT. It adds 50 tokens to every session and 1,977 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 2026-08-30.
