Install postman for Codex and Claude Code

Installs for the current user
codex plugin marketplace add thelogicmatrix/lm-tools
codex plugin marketplace upgrade lm-tools
codex plugin add postman@lm-tools

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

Compatibility: the page URL and API slug “postman-3” remain stable.

  • Codex: postman-3@agent-plugin-marketplace → postman@lm-tools

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.

Get the source manually
git clone https://github.com/thelogicmatrix/lm-tools

Clone the source repository, then follow its setup instructions to add the plugin to a compatible client. The plugin root is postman/.

Included Skills1

postmanskills/postman/SKILL.md

Real outbound email from your own mailboxes, one identity per address. Cold outbound and replies onto an existing thread, byte-exact signature, recipient verification, live thread resolution, per-identity voice, and a read path that pulls a mailbox window down for a model to read. Use when asked to "send these emails", "reply to the recruiter", or "what's in the inbox". Proactively suggest when outreach has been drafted but nothing has verified the addresses. Nothing to do with Postman the API client.
