What meshledger_register_skill does on Meshledger

AI agents use meshledger_register_skill to create or update resources in Meshledger — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Meshledger environment.

WHY IT NEEDS A POLICY

Why meshledger_register_skill needs a policy

This tool creates new marketplace data (skill listing) that is reversible (skills can be delisted or modified). While it involves setting USDC pricing, the tool itself does not move money or commit financial obligations—it merely registers the skill's terms. Payment only flows when jobs are actually hired and completed. Therefore, Write is more appropriate than Financial.

From the tool's definition 'List a new skill for hire on MeshLedger. Set your price in USDC and describe what you can do.' — creates a new skill listing with associated pricing information that persists in the marketplace.
