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 | $0.00642 | $0.00642 |
| Opus 5 | $0.00321 | $0.00321 |
| Sonnet 5 | $0.00128 | $0.00128 |
| Haiku 4.5 | $0.00064 | $0.00064 |
Grade C, and why
ostack-saas AGENTS.md scanned grade C with 1 finding 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 7d 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

The opening of the file, as written. The whole thing — 51 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ostack — AI Engineering Workflow
ostack is a collection of SKILL.md files that give AI agents structured roles for software development. Each skill is a specialist: CEO reviewer, eng manager, designer, QA lead, release engineer, debugger, and more.
Available skills
Skills live in .agents/skills/. Invoke them by name (e.g., /office-hours).
| Skill | What it does |
|---|---|
/office-hours |
Start here. Reframes your product idea before you write code. |
/plan-ceo-review |
CEO-level review: find the 10-star product in the request. |
/plan-eng-review |
Lock architecture, data flow, edge cases, and tests. |
/plan-design-review |
Rate each design dimension 0-10, explain what a 10 looks like. |
/design-consultation |
Build a complete design system from scratch. |
/review |
Pre-landing PR review. Finds bugs that pass tests but break in prod. |
/investigate |
Systematic root-cause debugging. No fixes without investigation. |
/design-review |
Design audit + fix loop with atomic commits. |
/qa |
Open a real browser, find bugs, fix them, re-verify. |
/qa-only |
Same as /qa but report only — no code changes. |
/ship |
Run tests, review, push, open PR. One command. |
/document-release |
Update all docs to match what you just shipped. |
/retro |
Weekly retro with per-person breakdowns and shipping streaks. |
/browse |
Headless browser — real Chromium, real clicks, ~100ms/command. |
/setup-browser-cookies |
Import cookies from your real browser for authenticated testing. |
/careful |
Warn before destructive commands (rm -rf, DROP TABLE, force-push). |
/freeze |
Lock edits to one directory. Hard block, not just a warning. |
/guard |
Activate both careful + freeze at once. |
/unfreeze |
Remove directory edit restrictions. |
/ostack-upgrade |
Update ostack to the latest version. |

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.
