Caveat verdict

🟢 Trusted
No high-risk patterns surfaced by the deep scan — automated capability review, not behavioral proof.

Reads local files AND makes external network calls

Legitimate voice-layer skill for ElevenLabs/Twilio integration; self-configuration via virtual-desktop browses the provider's own site to write credentials to .env, which is explicitly disclosed and consistent with its stated purpose.

Automated static analysis — not a human review. Caveat flags capabilities, not confirmed intent, and can produce false positives. Disagree with this verdict? Use Dispute below.

What it does

These are capability combinations: each listed behavior occurs in the skill, but Caveat detects co-occurrence — it does not verify that one flows into another. Read the code to confirm a live chain.

Capability combination critical

Reads local files AND makes external network calls — the capabilities for data exfiltration co-occur (data-flow not verified)

LLM02 · LLM06 · ASI03

Capability combination high

Accesses credentials AND makes external network calls — potential credential theft

LLM02 · ASI03

Capability combination high

Accesses credentials AND writes files — may persist stolen credentials locally

LLM02 · LLM06 · ASI03

Capability combination medium

Both reads and writes files — verify scope is limited to intended directories

LLM06 · ASI02

Permission integrity

Makes network requests but does not declare curl/wget in required binaries

network_out

Performs file operations but does not declare file-accessing binaries

file_read+write

Code accesses API keys/tokens but declares no environment variables

credential_access

Installs packages at runtime — transitive dependencies are not auditable

package_install

Pattern match critical

Pipe-to-python pattern — remote code execution risk

SKILL.md · code · curl -s https://api.elevenlabs.io/v1/user -H "xi-api-key: $ELEVENLABS_API_KEY"

Pattern match critical

Pipe to python — executes piped content as Python code

SKILL.md · code · | python3

Pattern match high

apt-get install — installs system packages

SKILL.md · code · apt-get install

Pattern match medium

subprocess execution — runs system commands from Python

voice_generator.py · prose · downgraded · subprocess.run(

Pattern match low

Python os.environ.get — reads environment variable

voice_generator.py · prose · downgraded · os.environ.get(

Pattern match low

Python shutil file operation — copies/moves/deletes files

voice_generator.py · prose · downgraded · shutil.copy(

Why the tier is capped

Execution sink present in raw bytes (Hard Floor: class C/D). Final tier capped at Caution — cannot be lifted by any downgrade, example-payload opt-in, or allowlist.
