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.

SkillSpector: 2 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
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 | $0.00052 | $0.01180 |
| Opus 5 | $0.00026 | $0.00590 |
| Sonnet 5 | $0.00010 | $0.00236 |
| Haiku 4.5 | $0.00005 | $0.00118 |
Grade A, and why
feishu 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 9d 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 — 172 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Feishu CLI Integration
Interact with Feishu (Lark) workspace via the official lark-cli tool. All commands are executed through execute_shell.
Prerequisites
Before using Feishu commands, ensure the CLI is installed and authenticated:
# Install
npm install -g @larksuite/cli
# Initialize config (set app_id/app_secret)
lark-cli config init
# Authenticate (OAuth login)
lark-cli auth login --recommend
If commands fail with auth errors, tell the user to configure credentials in Settings > CLI Tools.
Command Pattern
All Feishu CLI commands follow this pattern:
lark-cli <domain> <action> [options]
lark-cli <shortcut> # + prefix shortcuts
Always use --format json for structured output, and --dry-run before destructive operations.
Calendar (日历)
# View today's agenda
lark-cli calendar +agenda --format json
# View specific date range
lark-cli calendar +agenda --from 2024-01-01 --to 2024-01-07 --format json
# Create event
lark-cli calendar +create-event --summary "Meeting" --start "2024-01-15T10:00:00" --end "2024-01-15T11:00:00"
# Check free/busy
lark-cli calendar +free-busy --from "2024-01-15T09:00:00" --to "2024-01-15T18:00:00" --format json
# List calendars
lark-cli calendar list --format json
Messenger (消息)
# Send message to a user
lark-cli message send --receive-id "user_id" --msg-type text --content '{"text":"Hello"}'
# Send message to a group
lark-cli message send --receive-id "chat_id" --receive-id-type chat --msg-type text --content '{"text":"Hello"}'
# List recent messages in a chat
lark-cli message list --chat-id "chat_id" --format json
Docs (文档)
# Create a new document
lark-cli doc create --title "My Document" --format json
# Get document content
lark-cli doc get --document-id "doc_id" --format json
# Update document
lark-cli doc update --document-id "doc_id" --content '{"body":{"content":[]}}'
Drive (云盘)
# Upload file
lark-cli drive upload --local-path "/path/to/file.pdf" --parent-node "folder_id"
# Download file
lark-cli drive download --file-token "file_token" --local-path "/path/to/save/"
# List folder contents
lark-cli drive list --folder-token "folder_token" --format json
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 is a skill published in the GitHub repository vibeinging/YiYi (51 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 52 tokens to every session and 1,180 once invoked, about $0.0003 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.
