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 | $0.03501 | $0.03501 |
| Opus 5 | $0.01750 | $0.01750 |
| Sonnet 5 | $0.00700 | $0.00700 |
| Haiku 4.5 | $0.00350 | $0.00350 |
Grade A, and why
polaris 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 3d 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.
This is a copy
89% identical to polaris copilot-instructions.md — 14 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 — 184 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Polaris
這個 workspace 是什麼
一組 skill。每支 skill 自己的目錄裡帶著它需要的東西——腳本、參考文件、範例。
框架維護 skill，這是它的立場。 只有非常輕量的個人習慣留在框架裡，其餘都不是它的事。 一次工作要擴到 skill 以外之前，那是使用者的決定，不是推導得出來的結論。
一個名字不是根據。 某支腳本、某個欄位、某個目錄的名字看起來像在做某件事，不使它就是
那件事。要拿它當根據，先讀它真正被誰呼叫、回答什麼問題。2026-08-24 的標本：使用者要的是
「skill 分類」，而 skill_scope.py 這個名字被當成了那件事的權威——它五個呼叫者問的全部是
「這份東西會不會同步到 polaris」，沒有一個在問 skill 是哪一類。接下來三步全錯：拿那支
腳本碰得到的東西（rules、hooks、gate）當成範圍、宣布使用者的分類少一格、然後回頭改寫
使用者的指示。起點只是一個名字。
skill 分成三類，問的是同一個問題：這支工具是誰的。 目的地是類別的結果，不是類別的 定義：
| 類別 | 是誰的 | 進哪裡 |
|---|---|---|
universal |
大家的 | 公司 repo ＋ template repo |
company |
某一家公司的 | 只進公司 repo |
personal |
我的 | 哪裡都不進，留在 ~/.claude/skills/ |
每一份東西自己說出它是哪一類，核心不從名字或位置推導：skill 寫在 frontmatter 的
scope:，.claude/rules/ 與 .claude/hooks/ 沒有 frontmatter 可放，寫成一行
POLARIS-SCOPE: 標記。兩種寫法問的是同一份表——scripts/lib/skill_scope.py。
那份表是正向表列：只有列名的才出得去。 沒宣告的、宣告了表上沒有的值的、拼錯的， 三種都不出去。同步的目的地是一個公開 repo，讀寬了收不回來。
「不依賴環境」不是其中一格，它是所有 skill 的開發準則。 每一支都要問同一個問題： 照這支 skill 自己的描述，把它做成通用、不依賴環境，是不是更好用？想像的使用者不是你， 是一個不會寫程式、連工作環境都初始化不了的人，由工程師把 skill 匯進他的 Claude Desktop。 在那裡不成立的東西，就是不該留在 skill 裡的東西——「主 checkout 在哪」「這個 workspace 的設定在哪」在那裡沒有答案，所以一支 skill 要嘛不問這些問題，要嘛問不到的時候說出來並 照樣工作。
個人的東西不進公司 repo。 這個 repo 的 origin 是一個公司的 GitHub，所以「留在 local」
的意思是留在使用者自己的地方。宣告了 personal 卻躺在這個 repo 裡，
gate-template-leaks.sh 會擋下來並指名。
東西住哪，看它負責誰
框架只負責它自己，一張單的工作只在 issues/ 那張單裡，skill 只負責 skill 自己。
沒有「慣例」這種理由：一個位置要嘛推導得出來，要嘛是錯的。
| 這個東西負責誰 | 住哪 |
|---|---|
| 整個 repo（每次 commit 掃全樹的那些檢查、git hooks、壓版） | <repo>/scripts/ |
| 某一支 skill | 那支 skill 自己的目錄 |
| 某一張單（一次性的驗證、探測、注入腳本） | issues/{那張單}/ |
以前這裡寫的是「沒有共用的腳本目錄，因為只有 skill 目錄會被帶走」。那句話是假的：
template repo 追蹤 .claude/rules/ 與 .claude/hooks/，skill 目錄從來不是唯一會被帶走
的東西。它把通道二的限制套到了通道一的內容上，代價是同一個名字散在好幾支 skill 底下的
那些副本——其中回答「這個 workspace 的某個東西在哪」的那幾類，在通道二那些環境裡根本
沒有答案，複製過去只是雜訊。現在有幾份，問它：
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.
