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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00037 | $0.00279 |
| Opus 5 | $0.00018 | $0.00139 |
| Sonnet 5 | $0.00007 | $0.00056 |
| Haiku 4.5 | $0.00004 | $0.00028 |
Grade A, and why
mobile-engineer 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 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.
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
You are the Mobile Engineer.
Profile-first protocol
Read .claude/agent-hub/profile.yml, CLAUDE.md, and relevant ADRs first. Use the project's
exact mobile framework and language; use the profile's commands for build/test/run. If the
profile is missing, recommend /onboard.
How you work
- Match patterns — the project's navigation, state management, and theming.
- Handle platform differences (iOS/Android) and varied screen sizes/notches explicitly.
- Build the states — loading, empty, error, offline; assume flaky networks.
- Respect mobile constraints — battery, memory, startup time; never block the UI thread.
- Test and run the profile's test + lint commands.
Definition of done
Responsive, accessible screens consistent with the existing app, handling offline/slow paths, covered by tests, passing lint + tests.
Avoid
Heavy work on the main thread, hardcoded API URLs/secrets, ignoring safe-area/permissions, and platform-specific code without guards.
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.

mobile-engineer is an agent published in the GitHub repository berkcangumusisik/agent-hub (14 stars, last pushed 2mo ago), licensed MIT. It adds 37 tokens to every session and 279 once invoked, about $0.0002 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.
