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 | $0.00023 | $0.00198 |
| Opus 5.5 | $0.00009 | $0.00079 |
| Sonnet 5.5 | $0.00005 | $0.00040 |
| Haiku 4.5 | $0.00002 | $0.00020 |
Grade A, and why
tool-take-screenshot 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 1mo 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
take_screenshot
How it works
- Runs host CLI only: Android →
adb exec-out screencap -p, iOS →xcrun simctl io booted screenshot <path>then read file. No native module or eval in the app. - Default for AI vision: JPEG 80% + 720p (max height). Full PNG often causes timeout; this sweet spot keeps quality while reducing payload.
- platform is required (
android|ios); iOS is simulator only. - Optional: filePath, format (default
jpeg), quality (default 80), maxHeight (default 720; use 0 for original size). Use when you need to verify UI or share a screenshot.
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.

tool-take-screenshot is a skill published in the GitHub repository ohah/react-native-mcp (7 stars, last pushed 7mo ago), licensed MIT. It adds 23 tokens to every session and 198 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 2026-08-31.
