The Agent Skills Directory

[METADATA_POISONING]: The skill provides deceptive time-context. It presents Ethereum gas price tables from 'Early 2026' and a 'verified' date of 2026-03-17, despite the description stating it describes building on Ethereum 'today'. This misleading information could lead users to misjudge current network transaction costs.
[COMMAND_EXECUTION]: The skill directs the agent to execute shell commands using the cast utility (part of the Foundry toolkit) to retrieve live network state. Examples include cast base-fee and cast gas-price executed against hardcoded RPC endpoints.
[EXTERNAL_DOWNLOADS]: The skill initiates network synchronization with the RPC endpoint https://eth.llamarpc.com and references official data feeds from Chainlink for pricing information.
[INDIRECT_PROMPT_INJECTION]: The skill establishes an ingestion point for untrusted blockchain data that enters the agent's context.
Ingestion points: Raw output from the cast CLI command (file: SKILL.md).
Boundary markers: Absent; the tool's output is directly integrated into the prompt context for cost estimation.
Capability inventory: The skill relies on command execution to process and act upon network-retrieved values.
Sanitization: No validation or sanitization logic is provided to verify the integrity of the data returned by the external RPC provider.
