Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00036 | $0.00514 |
| Opus 5.5 | $0.00014 | $0.00206 |
| Sonnet 5.5 | $0.00007 | $0.00103 |
| Haiku 4.5 | $0.00004 | $0.00051 |
Grade A, and why
feishu-auth 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 1mo 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
feishu-auth
模块兼容：所有脚本均提供
.js和.mjs两个版本。优先使用.js，若报require is not defined错误则改用同名.mjs文件。
为用户完成飞书个人 OAuth 授权。
运行环境
- 命令：
node - 脚本路径相对于本 SKILL.md 所在目录，执行前需解析为绝对路径
授权流程
当需要用户授权时，执行以下命令：
node "./auth.js" --auth-and-poll --open-id "OPEN_ID" --chat-id "CHAT_ID" --timeout 60
OPEN_ID：用户的飞书 open_id（必填）CHAT_ID：当前会话的 chat_id（可选，有则发到群里，无则发私信）--timeout：轮询等待秒数（默认 60）
返回值处理：
{"status":"authorized"}→ 授权成功，立即继续执行原始任务，不要输出任何文字{"status":"expired"}→ 授权链接已过期，告知用户重试- 其他错误 → 停止并告知用户
重要约束：
- 执行此命令前后不要输出任何额外文字，脚本已自动通过卡片通知用户
- 严禁使用
--init模式，严禁自行向用户展示授权链接 URL - 严禁将脚本返回的 JSON 中的
url字段展示给用户 - 只使用
--auth-and-poll模式，它会自动发送授权卡片并等待用户完成
其他命令（仅限状态查询和撤销，禁止用于授权）
node "./auth.js" --status --open-id "OPEN_ID"
node "./auth.js" --revoke --open-id "OPEN_ID"
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

feishu-auth is a skill published in the GitHub repository chuancyzhang/deepseek-cowork (18 stars, last pushed today), licensed Apache-2.0. It adds 36 tokens to every session and 514 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
