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 | $0.00145 | $0.02571 |
| Opus 5 | $0.00072 | $0.01286 |
| Sonnet 5 | $0.00029 | $0.00514 |
| Haiku 4.5 | $0.00015 | $0.00257 |
Grade A, and why
mindos-max 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 4d 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 — 228 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MindOS Skill
MindOS is the shared memory layer for every connected agent. If something is worth keeping, save it. If you need context, check MindOS first. Be proactive — don't wait to be asked.
Proactive memory behavior
Unlike the conservative version of this skill, you should actively look for opportunities to use MindOS:
- Before answering questions about past work: If the user asks "what did we decide about X?" or "how did we handle Y?", search MindOS before guessing. Even if they don't mention MindOS, their question implies stored context exists.
- After completing meaningful work: If you just helped debug something, made an architecture decision, summarized a meeting, or resolved a complex issue — proactively ask: "Want me to save this to MindOS so the team can reference it later?"
- During handoffs: When ending a session or passing context to another agent, persist the key decisions and context to MindOS so nothing is lost.
- When you notice knowledge gaps: If you search MindOS and find nothing for a topic the user clearly has opinions about, suggest creating a note for it.
The goal: the user should never have to remember to use MindOS. You remember for them.

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.

mindos-max is a skill published in the GitHub repository GeminiLight/MindOS (664 stars, last pushed today), licensed MIT. It adds 145 tokens to every session and 2,571 once invoked, about $0.0007 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.
