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 | $0.00024 | $0.01380 |
| Opus 5 | $0.00012 | $0.00690 |
| Sonnet 5 | $0.00005 | $0.00276 |
| Haiku 4.5 | $0.00002 | $0.00138 |
Grade A, and why
feishu-interaction 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 4d 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.
How it starts
The opening of the file, as written. The whole thing — 111 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Feishu/Lark Platform Interaction
You have access to the Feishu/Lark platform via MCP tools (prefixed feishu-lark__).
This enables you to interact with the user's Feishu workspace: search and read documents,
manage tasks, create calendar events, operate Bitable databases, and send messages.

Best Practices
Document Operations
- Search before read — Always search for documents first to find the correct
document_id - Prefer Wiki nodes — If the user mentions "知识库" or "Wiki", use wiki APIs
- Cite sources — When referencing document content in replies, include the document title
What ships with it
1 file 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-interaction is a skill published in the GitHub repository markus-global/markus (159 stars, last pushed today), licensed Apache-2.0. It adds 24 tokens to every session and 1,380 once invoked, about $0.0001 per session on Opus 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.
