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 5.1 | $0.00020 | $0.00286 |
| Opus 5 | $0.00010 | $0.00143 |
| Sonnet 5 | $0.00004 | $0.00057 |
| Haiku 4.5 | $0.00002 | $0.00029 |
Grade A, and why
validate-mobile 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.
What it actually says
Validate Mobile
Invoke mobile-flows-maestro and run the flow in $ARGUMENTS.
Use the supplied path or discover the project's Maestro configuration. If more than one unrelated flow is plausible, choose from the requested feature or ask rather than running an arbitrary suite.
Determine the target platform from the flow, app configuration, and project
commands. Inspect booted iOS simulators with xcrun simctl list devices booted
and Android devices with adb devices; reject offline/unauthorized entries.
Use an already running compatible device when possible. If more than one is
available, select explicitly rather than relying on a default.
Verify flag placement with live help, then run the selected flow using the current equivalent of:
maestro --device "$DEVICE_ID" test "$FLOW"
On failure, follow the skill's classification before changing the flow. Inspect the failed step and relevant log tail. Retain a screenshot only when visual evidence can distinguish the cause, and keep image payloads in a bounded visual task when the host provides one.
Report the flow, platform, device, result, failed postcondition, and evidence.
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.

validate-mobile is a skill published in the GitHub repository johnkozaris/jko-claude-plugins (11 stars, last pushed 11d ago), licensed MIT. It adds 20 tokens to every session and 286 once invoked, about $0.0001 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.
