Usage Guidance
This skill's behavior (sending TTS to Feishu) matches its code, but the registry metadata incorrectly omits required environment variables. Before installing: 1) do not use high-privilege or production Feishu credentials — create a dedicated app/account with minimal scopes and test there; 2) confirm you are comfortable that message text will be sent to external TTS services (edge-tts/Microsoft) and to Feishu; 3) verify the publisher's project URL (https://github.com/Mayiv-Ai/feishu-voice) and confirm the repo matches the packaged scripts; 4) request the publisher to update the registry metadata to declare FEISHU_APP_ID and FEISHU_APP_SECRET (and any other env vars) so required secrets are visible up front; 5) consider running the scripts in a sandboxed environment first. The code itself shows no obvious exfiltration beyond the described APIs, but the metadata omission is a practical security/usability concern.
Capability Analysis
Type: OpenClaw Skill
Name: mayiv-feishu-voice
Version: 1.0.1
The skill bundle provides a legitimate utility for converting text to speech via Edge TTS and sending it to Feishu. It correctly handles credentials using environment variables (FEISHU_APP_ID, FEISHU_APP_SECRET) and interacts only with official Feishu API endpoints (open.feishu.cn). The shell scripts (feishu-send.sh, feishu-voice-send.sh) use standard tools like ffmpeg and python3 for processing without any signs of obfuscation, data exfiltration, or malicious intent.
Capability Assessment
Purpose & Capability
The skill claims to convert text to speech and send to Feishu, which legitimately needs FEISHU_APP_ID and FEISHU_APP_SECRET. However the registry metadata lists no required environment variables or primary credential even though both the SKILL.md and the shipped scripts require FEISHU_APP_ID and FEISHU_APP_SECRET. That omission is an incoherence between claimed requirements and actual capabilities.
Instruction Scope
The SKILL.md and scripts stay within the stated purpose: they run edge-tts + ffmpeg locally, then call Feishu open APIs (https://open.feishu.cn) to upload and send audio. They create temporary files and use curl/python to parse responses. They do not read unrelated system files or attempt to access other credentials. Note: text is sent to an external TTS provider (edge-tts/Microsoft services) and to Feishu APIs — users should be aware their message content is transmitted externally.
Install Mechanism
There is no automated install spec (instruction-only plus two shell scripts). Dependencies are typical (edge-tts via pip, ffmpeg). No remote downloads or archive extraction are performed by the skill itself, which reduces install-time risk.
Credentials
The code requires sensitive environment variables (FEISHU_APP_ID and FEISHU_APP_SECRET) to obtain a tenant access token. Those credentials are appropriate for Feishu integration, but the registry metadata fails to declare them. This mismatch could lead users to install/run the skill without realizing they must provide secrets. The skill will transmit provided text to external services (TTS + Feishu) — disclose this to data owners and use least-privilege credentials.
Persistence & Privilege
The skill is not always-enabled and does not request elevated platform privileges. It does not modify other skills or system-wide agent settings. It only runs scripts when invoked.
