ClawAudit verdict

black-fortress

88
🟢 Trusted
Low risk — reviewed by ClawAudit, behavior matches stated purpose

Receives external input AND executes processes

A pre-installation sandboxing protocol that runs untrusted code inside Docker containers with seccomp and a 5-layer analysis gate before approving execution; the described architecture is a defensive security tool with no exfiltration or deceptive behavior.

Automated static analysis — not a human review. ClawAudit 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 ClawAudit detects co-occurrence — it does not verify that one flows into another. Read the code to confirm a live chain.

Capability combination critical

Receives external input AND executes processes — the shape of a command & control channel

LLM05 · LLM06 · ASI10

Capability combination critical

Accesses system credential store AND makes external network calls

LLM02 · ASI03

Capability combination high

Executes processes AND makes external network calls — may exfiltrate command output

LLM02 · LLM06 · ASI03

Permission integrity

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

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.
