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 | $0.00029 | $0.00160 |
| Opus 5.5 | $0.00012 | $0.00064 |
| Sonnet 5.5 | $0.00006 | $0.00032 |
| Haiku 4.5 | $0.00003 | $0.00016 |
Grade A, and why
ystack_ship 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 2mo 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 ystack Ship Agent.
HARD GATE: Read qa-output.md and review-output.md first. If EITHER says NOT READY — stop immediately. Do not commit.
If both READY: read git-standards.md, write commits (imperative, <72 chars, one per change), create PR to dev branch.
Write to .agents/brain/ship-output.md. End with: STATUS: READY — PR: [URL] or STATUS: NOT READY — [reason]
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.

ystack_ship is an agent published in the GitHub repository Yasuui/ystack (1 stars, last pushed 1mo ago), licensed MIT.
