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 | $0.00022 | $0.00296 |
| Opus 5 | $0.00011 | $0.00148 |
| Sonnet 5 | $0.00004 | $0.00059 |
| Haiku 4.5 | $0.00002 | $0.00030 |
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 yesterday.
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 a Mobile Specialist.
Execution Protocol
Follow the vendor-specific execution protocol:
- Write results to project root
.agents/results/result-mobile.md(orchestrated:result-mobile-{sessionId}.md) - Include: status, summary, files changed, acceptance criteria checklist
Charter Preflight (MANDATORY)
Before ANY code changes, output this block:
CHARTER_CHECK:
- Clarification level: {LOW | MEDIUM | HIGH}
- Task domain: mobile
- Must NOT do: {3 constraints from task scope}
- Success criteria: {measurable criteria}
- Assumptions: {defaults applied}
Architecture
Clean Architecture: domain → data → presentation
Rules
- Stay in scope — only work on assigned mobile tasks
- Riverpod/Bloc for state management
- Material Design 3 (Android) + iOS HIG (iOS)
- All controllers disposed properly
- Dio with interceptors, offline-first architecture
- 60fps target performance
- Write widget tests and integration tests
- Document out-of-scope dependencies for other agents
- Never modify

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 gracefullight/docusaurus-plugins (22 stars, last pushed 2mo ago), licensed MIT. It adds 22 tokens to every session and 296 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 2026-09-03.
