thememoria

thememoria is a skill for Claude Code, Codex from matrixorigin/memoria. It costs 70 tokens per session (683 once invoked), scanned A, original, Apache-2.0.

A connection between OpenClaw and Memoria, a separate system for storing information across sessions. It covers saving, finding, correcting, deleting, backing up, and branching stored memories.

In plain words
What is it for?
Use it to remember durable facts, resume earlier work, correct or forget stored information, and create snapshots or branches before risky changes.
Why use it?
It prevents useful project facts and decisions from being lost when a conversation ends, while providing ways to repair or undo memory changes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

thememoria scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Memoria

Use this skill when OpenClaw should treat Memoria as the durable external memory system for the current user or project.

Routing

Pick the smallest reference that matches the task:

  • Install or verify the OpenClaw plugin: references/setup.md
  • Decide which memory tool to use: references/tool-surface.md
  • Daily store, recall, correct, forget behavior: references/operations.md
  • Session lifecycle, goals, recovery, branches, rollback: references/patterns.md

Core Rules

  1. Prefer Memoria tools over MEMORY.md or memory/YYYY-MM-DD.md unless the user explicitly asks for file-based notes.
  2. Do not auto-store every turn. Save durable facts, preferences, decisions, workflows, and meaningful progress.
  3. On task resume or "what do you remember" prompts, retrieve relevant memory first.
  4. Use the most specific tool available: memory_profile for stable preferences, memory_store for general durable memory, memory_correct or memory_forget for repairs.
  5. Before bulk delete, purge, or large rewrites, create a snapshot first.
  6. Use branches for risky or reversible memory experiments, then diff and merge or delete.
  7. After important writes, repairs, rollback, or merges, verify with retrieval or list tools.
  8. Do not claim only memory_search or memory_get exist when other memory_* tools are available.

Default Flow

  1. At conversation start or task resume, use memory_retrieve or memory_search for relevant context.
  2. During the conversation, store only the durable facts worth keeping.
  3. If the user corrects or removes memory, repair it immediately with memory_correct, memory_forget, or memory_purge.
  4. For risky memory maintenance, create a snapshot or branch before mutating state.
  5. At the end of meaningful work, store the durable outcome and clean up obsolete working memory.

Important Notes

  • OpenClaw's built-in file memory (openclaw memory) is separate from Memoria (openclaw memoria).
  • The plugin defaults to explicit writes, not silent auto-capture.
  • memory_get is a compatibility helper; when in doubt, prefer memory_retrieve, memory_search, or memory_list.
  • Memoria's core strengths are semantic retrieval, durable cross-session memory, snapshots, rollback, branches, merge, and governance.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

thememoria is a skill published in the GitHub repository matrixorigin/memoria (592 stars, last pushed 9d ago), licensed Apache-2.0. It adds 70 tokens to every session and 683 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
