Feishu Doc Block Writer

Security checks across static analysis, malware telemetry, and agentic risk

Overview

The listing describes an image-generation skill, but the included instructions are for automatically creating Feishu documents using scripts that are not included for review.

Install only if you specifically want a Feishu document-writing skill, not an image generator. Before using it, verify the missing scripts, correct the registry description, require explicit confirmation for every document write, and use a limited Feishu account/folder.

Risk analysis

Artifact-based informational review of SKILL.md, metadata, install specs, static scan signals, and capability signals. ClawScan does not execute the skill or run runtime probes.

#
ASI09: Human-Agent Trust Exploitation
Medium
What this means

You might install or invoke it expecting image generation, while it is designed to create and write Feishu documents.

Why it was flagged

This registry-facing description conflicts with SKILL.md, which describes Feishu document creation and block writing. Users or agents could trust the listing and invoke a capability different from what the skill instructions actually do.

Skill content
Description: Generate/edit images with Nano Banana Pro (Gemini 3 Pro Image).
Recommendation

Do not install until the listing description and the skill contents are made consistent.

#
ASI02: Tool Misuse and Exploitation
Medium
What this means

Long replies or Mermaid content could lead to unintended Feishu documents being created or populated.

Why it was flagged

The skill tells the agent to automatically trigger on broad conditions and then create/append Feishu document content. That can mutate an external workspace even when the user did not explicitly ask to create a document.

Skill content
自动触发:- 内容超过 500 字 ... - 回答超过 200 字(200 字规则) - 包含 Mermaid 图表 ... 核心原则:使用 `create` 创建空文档;使用 `append` 逐块追加内容
Recommendation

Require explicit user confirmation before creating or appending any Feishu document, and narrow automatic triggers to direct document-creation requests only.

#
ASI04: Agentic Supply Chain Vulnerabilities
Medium
What this means

The skill may fail, or worse, the agent may run a local script that was not supplied or reviewed with this package.

Why it was flagged

The instructions reference runnable scripts such as block-writer.py and create-doc-template.py, but those scripts are not included in the reviewed package. Any execution would depend on missing or local unreviewed code.

Skill content
No code files present — this is an instruction-only skill. File manifest: QUICK-REFERENCE.md, skill.json, SKILL.md, TEST-REPORT.md
Recommendation

Publish the referenced scripts with the skill, add an install spec, and ensure all executable code is reviewed before use.

#
ASI03: Identity and Privilege Abuse
Low
What this means

The skill can create and write documents in the Feishu workspace associated with the configured tool or account.

Why it was flagged

Using Feishu account/workspace authority is expected for a Feishu document writer, but the registry requirements declare no primary credential or capability tags, so users need to verify what account and permissions will be used.

Skill content
飞书凭证(可选)... 调用 feishu_doc 创建空文档 ... 逐块追加内容
Recommendation

Use a least-privileged Feishu account, confirm the target tenant/folder before each write, and document the credential requirements in metadata.

#
ASI06: Memory and Context Poisoning
Low
What this means

Feishu document references may persist locally and could be reused in later agent tasks.

Why it was flagged

The recommended template describes persistent memory logging. This is related to archive tracking, but it may retain document links, folder tokens, titles, or other metadata for later context.

Skill content
自动写入归档记录到 memory/YYYY-MM-DD.md
Recommendation

Confirm what is written to memory, avoid logging sensitive document details, and provide a clear cleanup or opt-out option.
