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

Accesses credentials AND encodes data

Authentication pattern guide providing reference implementations for API key, OAuth, and token management; purely instructional with no unexpected external calls.

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 high

Accesses credentials AND encodes data — may obfuscate stolen credentials

Permission integrity

Code accesses API keys/tokens but declares no environment variables

Findings (3)

Pattern match critical

Possible hardcoded credential

modules/auth-methods.md · code · API_KEY="your-key-here

Pattern match high

subprocess execution — runs system commands from Python

SKILL.md · code · subprocess.run(

Pattern match medium

Python os.getenv — reads environment variable

SKILL.md · code · os.getenv(

Why the tier is capped

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

Permissions & capabilities

No declared permissions — minimal attack surface.
