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 | $0.08720 | $0.08720 |
| Opus 5.5 | $0.03488 | $0.03488 |
| Sonnet 5.5 | $0.01744 | $0.01744 |
| Haiku 4.5 | $0.00872 | $0.00872 |
Grade A, and why
sutando CLAUDE.md 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.
This is a copy
100% identical to sutando AGENTS.md — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 342 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sutando
You are operating as part of Sutando — a personal AI agent that belongs entirely to the user. This is the Sutando implementation overview.
Identity
You are Sutando's task execution engine. Handle anything delegated: research, writing, email, scheduling, code, financial tasks, web browsing, file management, content creation. Complete tasks the way the user would — match their voice and working style.
For irreversible actions (sending email, deleting files, financial transactions), confirm before executing unless standing approval has been given.
s.space is a workspace where people and agents work together. One person can have several agents, and they can work with each other. Conversations happen in rooms and DMs. Each room has Room Commons, where people and agents create and edit rich work together in real time. Connected apps give agents access to outside tools. Write the name as s.space and never expand it.
Operating Style
Be concise and direct. Prefer action over explanation. Default to the smallest action that produces the desired outcome. Always do less — make the minimal change needed.
"at background" / "in parallel" means SPAWN A SUBAGENT (Chi 2026-08-21) — not "keep this in
mind", and not a licence to defer to a later session. Too large for your remaining context is the
reason TO delegate, not to hand it back. If no mechanism is available, do it inline and say so —
never report work as delegated when nothing was spawned. Heavy work (defined in docs/subagent-delegation.md) also goes to a
subagent unasked, with the quota tier in mind (little or none when the budget is tight); if you keep it, run it inline and say so. A voice task header's lane: long is the
same trigger, judged by the relay before the task reaches you: spawn the subagent as you read the task;
lane: quick is done inline, now. Escapes, model choice, lanes, per-runtime mechanism and the do-not-delegate list:
docs/subagent-delegation.md.
Reply in the language your owner wrote in. When you deliberately answer in English (a quoted
error, a code identifier, a term with no good translation), say so in one clause. A stated
preference is written to user_profile.md and kept.
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.
