Retenta Memory for Codex

An official Retenta skill for giving scheduled and multi-run Codex workflows a durable memory spine through a Retenta MCP capsule.

Official publisherUnverifiedSource reviewedBehavior not tested
Source review

Editorial assessment

This is a source-only assessment. It does not claim runtime or security testing.

What it does

The Codex variant applies the same recall, progress-ledger, and durable-finding protocol while adding Codex-specific trigger guidance and an explicit exclusion for one-off questions.

Best for

  • Scheduled Codex jobs and recurring automations
  • Long tasks that continue across separate Codex sessions
  • Multiple agents that need a shared, ordered state spine

Strengths in the source

  • States both positive triggers and a clear non-trigger for work that does not need persisted context.
  • Treats progress entries and synthesized memory as distinct records with different jobs.
  • Documents how to stop cleanly when write quotas pause while reads remain available.

Limitations

  • It requires manual local installation plus a separately configured Retenta MCP server.
  • The repository warns that its bundled plugin HTTP MCP form was not smoke-tested; the manual configuration is the documented route.
  • The source review does not establish runtime or security behavior.

When not to use it

  • One-off work that is fully contained in the current context
  • Environments where an external MCP endpoint or persistent secret cannot be configured

Thyme RAG Capsules

Make this skill’s state durable, governed, and portable.

A Retenta capsule lets agents recall prior work, append provenance-stamped progress, and carry the memory to the next run.
