Highest confirmed finding severity

High

2 confirmed security findings require attention.

Installation context

Check the current Skill page

This page summarizes report evidence only. The Skill page provides the canonical install advisory.

Open current Skill page

This report does not block or authorize the manifest or ZIP.

Most static findings are false positives caused by Markdown formatting or benign environment variable examples. Confirmed findings cover remote documentation fetches, third-party installation, and bot execution; semantic review also identified irreversible blockchain actions and tolerance of unresolved failures.

Report position

Limitations

This report does not claim runtime or sandbox execution and does not prove the absence of side effects.

Evidence chain

Follow the evidence from source binding to the install contract. Available evidence supports verification; it is not a safety guarantee.

Capability review items (5)
Medium
SKILL.md:113-115
Ruby/shell backtick execution
```bash
The cited fenced block instructs the agent to run uv tool install silverback. Installing an unpinned third-party package executes externally supplied code.
Medium
SKILL.md:120-122
Ruby/shell backtick execution
```bash
The cited Bash block runs the generated bot against a user-selected blockchain network. Executing generated automation can trigger network and signer side effects.
Low
SKILL.md:17
Hardcoded URL
1. Use `web_fetch` to retrieve the latest documentation from https://docs.apeworx.io/silverback/stab
The skill explicitly requires fetching content from the hardcoded documentation host. The official destination limits risk, but remote content remains mutable.
Low
SKILL.md:19
Hardcoded URL
- Development guide: https://docs.apeworx.io/silverback/stable/userguides/development
This URL is listed as a page the agent should fetch. It creates an outbound dependency on mutable remote documentation.
Low
SKILL.md:20
Hardcoded URL
- API reference: https://docs.apeworx.io/silverback/stable/methoddocs
This API reference URL is another explicit fetch target. The domain is official, but the response is external and mutable.

Risk findings

Confirmed security concerns are separated from items that still need review.

Confirmed security concerns (2)

RISK-001 High
SKILL.md:36-43SKILL.md:107-122
Generated Bot Can Perform Irreversible Blockchain Actions
The workflow can create and run handlers that sign and broadcast transactions. Mainnet execution may cause irreversible financial or contract state changes.
The skill explicitly lists signed transaction broadcasting as a handler action and provides a command that can target ethereum:mainnet.
RISK-002 Medium
SKILL.md:124-128
Unresolved Failures May Be Accepted During Testing
The skill says continued testing may be acceptable when failures remain unexplained. Faulty blockchain automation can repeat unintended actions or hide unsafe state handling.
The guidance directly permits continued testing despite unresolved failures, although it does not recommend production deployment in that state.

Remediation

Suggested fixes recorded by this audit. Applying them is the maintainer’s responsibility.

  1. FIX-001
    High
    The workflow installs an unpinned tool and can run generated automation on a user-selected network, including mainnet.
    Require explicit confirmation, pin a reviewed Silverback version, default to testnet, and require separate approval before enabling a signer or mainnet.
  2. FIX-002
    Medium
    The skill permits continued testing when failures remain unexplained.
    Require fail-closed behavior and resolve transaction, signer, and state errors before further privileged or funded testing.
