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.

SkillSpector: 1 finding, up to medium
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 →
- medium Rogue Agent · line 103 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
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 | $0.00081 | $0.01818 |
| Opus 5 | $0.00041 | $0.00909 |
| Sonnet 5 | $0.00016 | $0.00364 |
| Haiku 4.5 | $0.00008 | $0.00182 |
Grade A, and why
mobiai-brain 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 12d 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 — 148 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MobiAI Brain
Per-project living memory for mobile projects. Lives at <repo>/.mobiai/brain/ — separate from MobiAI's global state in ~/.mobiai/. Each project has its own brain; nothing is shared between projects.
When to invoke this skill
- User asks "what did we decide about X?" / "why is Y like that in this project?" / "is this workaround still needed?"
- You are about to propose changes to architecture, dependency injection, networking, persistence, testing strategy, or third-party integrations.
- User mentions an integration that often has project-specific quirks (Firebase, push, payments, auth).
- User starts a fresh session in a mobile project and you need quick orientation.
If the project has no .mobiai/brain/ yet and the user wants project memory, suggest running mobiai brain init. Don't run it yourself unless asked.
Commands available today
mobiai brain init # Create .mobiai/brain/ in the project (idempotent)
mobiai brain scan # Detect stack: Android / iOS / KMP / Flutter / RN + libs
mobiai brain context # Print Markdown context: config + scan + memories (filterable)
mobiai brain save decision # Append an architecture decision
mobiai brain save bugfix # Append a bugfix or workaround
mobiai brain save testing # Append a reusable testing pattern
mobiai brain search <query> # Free-text search over memories
mobiai brain mcp # Start an MCP server exposing the brain as tools
Prefer MCP tools when available
If your client (Claude Code, Cursor, Copilot CLI, Codex, Gemini CLI) has mobiai-brain registered as an MCP server, you'll see tools named mobile_context, mobile_search, mobile_scan, mobile_save_decision, mobile_save_bugfix, mobile_save_testing in your toolbox. Use those instead of shelling out to the CLI — they return structured output (JSON for search/scan, Markdown for context) that's easier to reason about and cite.
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.

mobiai-brain is a skill published in the GitHub repository ArisGuimera/MobiAI-Core (453 stars, last pushed 4d ago), licensed MIT. It adds 81 tokens to every session and 1,818 once invoked, about $0.0004 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.
