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 | $0.00060 | $0.04575 |
| Opus 5.5 | $0.00024 | $0.01830 |
| Sonnet 5.5 | $0.00012 | $0.00915 |
| Haiku 4.5 | $0.00006 | $0.00458 |
Grade A, and why
documents 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.
How it starts
The opening of the file, as written. The whole thing — 596 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Lark Documents Skill
Query and retrieve Lark document content via the lark CLI.
Running Commands
Ensure lark is in your PATH, or use the full path to the binary. Set the config directory if not using the default:
lark doc <command>
# Or with explicit config:
LARK_CONFIG_DIR=/Users/yingcong/Code/lark-cli/.lark lark doc <command>
Commands Reference
Search Documents
lark doc search <query> [--owner <user-id>] [--chat <chat-id>] [--type <doc-type>]
Searches for documents by keyword. Returns documents from Drive that match the query.
Options:
--owner: Filter by owner user ID (can be repeated)--chat: Filter by chat ID where document is located (can be repeated)--type: Filter by document type (can be repeated). Valid types:doc,sheet,slide,bitable,mindnote,file
Output:
{
"query": "project plan",
"results": [
{
"token": "doxcntan34DX4QoKJu7jJyabcef",
"type": "docx",
"title": "Q4 Project Plan",
"owner_id": "ou_xxxx"
}
],
"total": 15,
"count": 15
}
Note: Maximum 200 results can be returned per search.
List Folder Items
lark doc list [folder-token]
Lists items in a Lark Drive folder. If no folder token is provided, lists items in the root cloud space.
Output:
{
"folder_token": "fldbcRho46N6MQ3mJkOAuPabcef",
"items": [
{
"token": "doxcntan34DX4QoKJu7jJyabcef",
"name": "My Document",
"type": "docx",
"parent_token": "fldbcRho46N6MQ3mJkOAuPabcef",
"url": "https://larksuite.com/docx/doxcntan34DX4QoKJu7jJyabcef"
}
],
"count": 1
}
Item types: doc, docx, sheet, bitable, mindnote, file, folder, shortcut
For shortcuts, includes shortcut_info with target_type and target_token.
Download File from Drive
lark doc download <file_token> -o <output_path>
Downloads a file from Lark Drive. The file token is obtained from doc list or doc search output. Only files with type "file" can be downloaded (not docs, sheets, etc - those are Lark native formats).
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.

documents is a skill published in the GitHub repository yjwong/lark-cli (54 stars, last pushed 6mo ago), licensed MIT. It adds 60 tokens to every session and 4,575 once invoked, about $0.0002 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.
