⚡ Installation (NEW!)

One-Command Installation

bash install.sh

The installer automatically:

✅ Detects your system architecture (ARM64, x86_64)
✅ Downloads Piper TTS
✅ Downloads 4 Brazilian Portuguese voice models (~240MB)
✅ Installs Python dependencies
✅ Validates everything works

No manual downloads. No configuration. Just one command!

🔄 Critical Rules

DEFAULT: AUDIO ONLY - NO TEXT

When user sends audio:

❌ NO transcription shown
❌ NO "Pesquisando...", "Gerando..."
❌ NO confirmations or explanations
✅ ONLY audio reply

TEXT MODE: Say "texto" or "responda em texto" explicitly

📊 Workflow

🎤 Audio Received (PT-BR/EN)
    ↓
🔤 Transcribe (wav2vec2 PT-BR - silent)
    ↓
🤖 AI Response (Claude API or OpenClaw Agent - silent)
    ↓
🗣️ Synthesize (Piper neural - silent)
    ↓
📤 Send Audio Reply (silent)

📁 Scripts

Installation & Setup

install.sh - Automatic installation (run once!)
health_check.py - Validate the installation

Core Processing

transcribe.py - wav2vec2 PT-BR speech recognition
synthesize.py - Piper TTS with voice selection
voice_config.py - Voice preference management
process.sh - Full workflow orchestration

AI Integration

claude_adapter.py - Claude API bridge (intelligent responses)

🔧 Configuration

Optional: Enable Claude Integration

For intelligent AI responses, set your API key:

export ANTHROPIC_API_KEY="sk-your-api-key"

Without this, the skill uses OpenClaw's agent (still great responses!).

安全使用建议

This package is not obviously malicious but contains actions you should review before running: 1) Inspect install.sh closely — it will download and extract binaries and voice models, run pip installs (torch, transformers, anthropic) and may invoke apt-get/homebrew (sudo may be required). Run it only in a controlled environment (VM, container, or a dedicated user account) if you don't fully trust it. 2) If you plan to use Claude, only set ANTHROPIC_API_KEY when you trust the code; otherwise the skill will fall back to local/OpenClaw responses. 3) Prefer installing Python dependencies in a virtualenv rather than globally; review and, if desired, pin or audit packages before pip installing. 4) Confirm network endpoints: GitHub releases and HuggingFace model URLs are used (expected) — verify these URLs if you need assurance. 5) If you want lower risk, run health_check.py and the individual scripts (transcribe/synthesize) manually first to validate behavior before running the one-command installer. 6) Because the registry metadata omits runtime tool requirements (python3, pip, ffmpeg, wget, jq), expect to manually satisfy those prerequisites or update the metadata. If you want, I can extract and summarize the claude_adapter.py, transcribe_universal.py and synthesize_universal.py files to highlight any code paths that contact external services or handle credentials.

功能分析

Type: OpenClaw Skill Name: audio-ptbr-aprimorado Version: 2.0.1 The skill provides a Brazilian Portuguese voice interface using local models and the Claude API. It is classified as suspicious primarily due to an invasive installation script (install.sh) that executes sudo commands to install system packages and downloads external binaries from GitHub and HuggingFace. Additionally, the SKILL.md instructions explicitly direct the AI agent to suppress all text output, transcriptions, and confirmations, which—while consistent with the stated 'voice-only' user experience—could be leveraged to obfuscate the agent's actions. The bundle also includes a 'SECURITY_REVIEW_RESPONSE.md' that acknowledges these risks, but the combination of broad media permissions and suppressed output remains a significant attack surface.

ℹ Purpose & Capability

The skill name and description (PT-BR ASR + local TTS + optional Claude integration) match the included scripts and workflow. However, the package/registry metadata declares no required binaries or env vars while the code and installer do require system tools (python3/pip, ffmpeg, wget/tar, jq is used at runtime) and optionally the ANTHROPIC_API_KEY. The implementation capabilities are appropriate for the stated purpose, but the metadata omission is inconsistent.

ℹ Instruction Scope

SKILL.md and process.sh limit runtime activity to: local transcription (wav2vec2), optional calls to Anthropic (when ANTHROPIC_API_KEY is present), local synthesis (Piper), and returning MEDIA: directives or calling openclaw CLI if available. There are no obvious instructions to read unrelated secrets or exfiltrate data. Caveats: process.sh invokes external commands and expects jq; environment.py auto-detection may read environment variables and filesystem paths (to detect OpenClaw/Claude contexts) — this is expected but broader than the minimal description. The documentation also instructs running install.sh which modifies system state (see install_mechanism).

⚠ Install Mechanism

There is no formal install spec in the registry, but an install.sh is included and described as 'one-command'. install.sh downloads Piper binaries from GitHub releases and voice models from HuggingFace (both reasonable sources), and uses wget/tar to extract them. It also attempts to auto-install system packages (python3, pip, ffmpeg) via apt-get or brew and runs pip install for heavyweight ML packages (torch/transformers/anthropic) globally unless a venv is present. That means: (a) arbitrary code (archives) are extracted to disk, (b) system package installation and global pip installs may require sudo/administrator rights, and (c) dependencies like jq and wget are relied upon but not declared in registry metadata. These behaviors increase risk and should be run only with review or in an isolated environment.

ℹ Credentials

The skill uses an optional ANTHROPIC_API_KEY for Claude integration (documented in SKILL.md), and otherwise uses non-secret environment values for configuration (AUDIO_VOICE, WORKSPACE, RESPONSE_TIMEOUT). The registry metadata lists no required env vars; the SKILL.md documents ANTHROPIC_API_KEY as optional. There are no requests for unrelated credentials. The main proportionality issue is the metadata omission of required runtime tools and the installer performing system package installs which effectively requires elevated privileges to set up.

✓ Persistence & Privilege

The skill does not request always:true and does not modify other skills. It writes files under the user's workspace (~/.openclaw/workspace, skill directory) and creates a voice config file there; this is a normal level of persistence for a skill. Installer actions and created files are limited to user workspace and downloaded binaries/models; nothing in the package attempts to alter other skills or global agent configuration beyond advising an openclaw restart.
