Install plugin

Installs for the current user
codex plugin marketplace add IchenDEV/agent-plugin-mkt
codex plugin marketplace upgrade agent-plugin-marketplace
codex plugin add hermes@agent-plugin-marketplace

Paste and run these commands in a terminal with Codex. They add and refresh the PluginsMP catalog, then install this plugin.

The installer fetches third-party code from the source repository shown on this page. This directory validates manifest structure and source location, but does not perform a security audit; review the manifest, components, and source before installing.

Included Skills1

hermesskills/hermes/SKILL.md

Optimise Solidity gas usage with an executable, fail-closed Foundry loop that measures savings, re-runs behaviour tests, checks storage layouts and method identifiers, and demands targeted differential or property evidence for state-sensitive unchecked arithmetic. Every candidate names a rule from a pinned corpus of 120 gas rules and 28 rejected ones, and the harness refuses a rule outside the target's compiler, fork or pipeline scope. Use for Solidity gas work, Forge snapshot reductions, gas-report reviews, storage packing, unchecked arithmetic, or any proposed EVM gas-saving change.
