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 | $0.20762 | $0.20762 |
| Opus 5.5 | $0.08305 | $0.08305 |
| Sonnet 5.5 | $0.04152 | $0.04152 |
| Haiku 4.5 | $0.02076 | $0.02076 |
Grade C, and why
objectstack AGENTS.md scanned grade C with 2 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 today.
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.
`pnpm install --frozen-lockfile && pnpm build && rm -rf packages/runtime/.objectstack` Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 1,118 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ObjectStack — AGENTS.md
Primary AI instruction file for this repo — and the human contributors' source of truth.
Read natively by Claude Code, GitHub Copilot (coding agent + CLI), and other agents — no
separate .github/copilot-instructions.md mirror needed. When any other instruction file
in this repo (including .claude/skills/**) conflicts with this one, AGENTS.md wins.
docs/NORTH-STAR.md (先做什么: goals, priority) outranks it; content/docs/concepts/north-star.mdx = architecture.
v5.0 breaking rename:
project→environmenteverywhere (CLI-e,/api/v1/environments/:id, headerX-Environment-Id,OS_ENVIRONMENT_ID, DB columnenvironment_id[control-plane tables; on the metadata tables since deprecated in favour oforganization_id, ADR-0006 v4]). No aliases. See ADR-0006. "Project" now only means the npm/monorepo sense.
This file carries principles, binding rules and lookup tables — rules only. A rule states
what to do and what never to do, in one executable sentence; it carries no incident
narrative, no ruling date or quotation, and no issue-number citation
(pnpm check:pm-skill-id-lint) — a rule's provenance cites the ADR or ruling record that
decided it, otherwise the commit sha in this repository's history; a PR number is a
convenience link, ⛔ never the citation. Runtime strings — refusal prose, prescriptions,
anything an author is shown — carry no tracker number (pnpm check:doc-authoring): the
lesson goes into the text. Where a hook or CI gate enforces a rule mechanically, the rule is
stated once here and the script's own header is the authority on detail.
Communication
语言规则分两件事:和维护者说话用什么语言,与留在 GitHub 上的产物用什么语言。
- 在 Claude Code 中与维护者对话一律使用中文(对话回复、轮次报告等聊天通道里的内容)。
- GitHub 产物一律使用英文:issue 与 PR 的标题、正文、评论。
- 引用中文裁决时保持原文、不翻译,即使承载它的 issue/PR 正文通篇是英文——改写引文 就是改写裁决。
- 代码、标识符、提交信息(commit messages)、ADR/文档正文等仓库产物保持现有语言惯例(以英文 为主),不要因本节而改写。
Build & Test
pnpm install # deps
pnpm run setup # first-time: install + build spec (bare `pnpm setup` is pnpm's own built-in)
pnpm build # turbo build (excludes docs)
pnpm test # turbo test
pnpm typecheck # turbo typecheck — per-package `tsc --noEmit`; tsup/vitest never type-check
pnpm docs:dev # docs site
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.

objectstack AGENTS.md is an instructions file published in the GitHub repository objectstack-ai/objectstack (75 stars, last pushed today), licensed Apache-2.0. It adds 20,762 tokens to every session, about $0.0830 per session on Opus 5.5. A static security scan graded it C with 2 findings (recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
