Codex Plugin Submission Note

July 29, 2026 ยท View on GitHub

Summary

XMemo for Codex connects Codex to XMemo's hosted MCP memory service.

Positioning:

Codex executes development. XMemo lets Codex remember the project.

Why It Belongs In Codex

Codex is strongest when it understands the project history, coding conventions, architecture decisions, and current handoff state. XMemo provides that durable context without embedding private project memory into the plugin package.

Reviewer Flow

Use synthetic reviewer data only.

  1. Install the plugin package.
  2. Configure XMEMO_KEY in the local environment.
  3. Confirm the MCP server is named XMemo and points to https://xmemo.dev/mcp.
  4. Ask Codex to recall context for a synthetic project.
  5. Ask Codex to save a synthetic engineering decision.
  6. Ask Codex to recall that decision in a new task.
  7. Revoke or unset credentials and confirm Codex shows an auth-required state without exposing secrets.

Test Materials

  • Five positive workflow prompts and three negative/boundary prompts are maintained in examples/review-prompts.md.
  • The package validator runs with python scripts/validate-package.py.
  • Connection diagnostics run with pwsh -File scripts/xmemo-codex-doctor.ps1.
  • The MCP-depth client smoke test runs with xmemo smoke --client codex.

This plugin has no custom UI. Screenshots are therefore omitted from manifest metadata in accordance with the current no-UI submission guidance.

Claims

This repository is prepared for Codex plugin review. It does not claim official Codex marketplace approval until an official review accepts it.
