Full Analysis
  • [REMOTE_CODE_EXECUTION]: The skill instructs the agent to download a setup script from https://tempo.xyz/install to /tmp/tempo_install.sh and execute it using bash in SKILL.md. This is done to install the Tempo CLI, which is necessary for the skill's primary operation.
  • [INDIRECT_PROMPT_INJECTION]: The skill processes untrusted response data from external HTTP 402 challenges to extract parameters like token addresses, amounts, and recipients.
  • Ingestion points: Handled in SKILL.md and references/credential-construction.md, where the agent parses the WWW-Authenticate header or JSON body of a 402 response.
  • Boundary markers: The skill contains explicit instructions to enforce strict validation rules on all parsed fields before usage.
  • Capability inventory: Uses tempo, cast, curl, and jq to execute requests, check balances, and sign transactions based on external inputs.
  • Sanitization: Employs explicit regex validation patterns for addresses, chain IDs, and amounts, and mandates the rejection of any input containing shell metacharacters like ;, |, &, or newlines. Additionally, it implements mandatory human-in-the-loop confirmation gates (AskUserQuestion) before any transaction execution or cryptographic signing.
Recommendations
  • HIGH: Downloads and executes remote code from: https://tempo.xyz/install - DO NOT USE without thorough review
