The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill provides instructions to download the Foundry installation script from foundry.paradigm.xyz, which is the official distribution point for the well-known Ethereum development toolkit.
[REMOTE_CODE_EXECUTION]: The documentation includes a setup step that pipes the downloaded Foundry script directly to the shell (curl ... | bash). The skill explicitly notes this as a standard practice that carries supply chain risks.
[COMMAND_EXECUTION]: The skill's primary function involves generating and executing shell commands using Foundry's cast tool to simulate (cast call) and broadcast (cast send) blockchain transactions.
[INDIRECT_PROMPT_INJECTION]: The skill processes structured JSON data from a preceding swap-build step to populate transaction fields.
Ingestion points: Reads transaction data (calldata, addresses, values) from the swap-build output in SKILL.md.
Boundary markers: Includes a mandatory 'Step 3: Confirm Execution' where the agent must present transaction details and wait for an explicit "yes" from the user before proceeding.
Capability inventory: Execution of shell commands via cast and potential execution of JavaScript snippets via ethers.js fallback.
Sanitization: Instructs the agent to validate input fields, simulate the transaction to check for reverts, and verify the router address against a known hardcoded value.
