Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00059 | $0.00646 |
| Opus 5.5 | $0.00024 | $0.00258 |
| Sonnet 5.5 | $0.00012 | $0.00129 |
| Haiku 4.5 | $0.00006 | $0.00065 |
Grade A, and why
using-memory 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 1mo 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 — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Using memxt memory
You have a persistent, local memory palace via the memory MCP server.
It survives across sessions. Nothing leaves this machine. No cloud LLM is used
to compress or store memory (unlike claude-mem-style pipelines).
Progressive disclosure (save tokens)
Always prefer this 2-step flow:
memory_search— defaultdetail=indexreturns compact hits (#id, wing/room, source, ~100-char snippet). Cheap.memory_get— pass promisingidoridsto load full verbatim bodies only for what you need.
Do not pass detail=full unless the query is tiny or you already know you
need every body (wastes context).
Example:
memory_search({ query: "cart limit", limit: 5 })
→ #42 decisions/… "Cart is capped at 37…"
memory_get({ ids: [42] })
→ full drawer text
Other tools
memory_wake_up— continuity brief (also auto-injected at SessionStart).memory_profile— stable project facts; no embedding model.memory_store— persist a decision / constraint / fact (verbatim). Preferroom: "decisions"for architecture choices.memory_forget— delete by drawer id.memory_stats/memory_dream— health / consolidation.
When to recall
Before answering "what / why / how did we …", "last time", "remember when", "our convention for …", or anything that depends on history:
memory_search(index)memory_geton relevant ids- Cite
#id/ source when you use a memory
When to store
After a real decision ("let's use X because Y"), a discovered constraint, a
correction the user makes, or a fact you'd want next session, call
memory_store. One crisp memory per fact.
Good:
"Cart is capped at 37 items because the Brightwell ERP rejects larger orders (0x5C error)."
Bad: "we talked about the cart."
Hooks already autosave session tails on Stop + PreCompact (local, verbatim).
Still call memory_store for important decisions so they land in the
profile, not only as a long episode.
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.
- 1mo ago First seen · 72 lines · 59 tokens per session scan A 518989b2a7d3
using-memory is a skill published in the GitHub repository Yupcha/memXT (49 stars, last pushed 2mo ago), licensed MIT. It adds 59 tokens to every session and 646 once invoked, about $0.0002 per session on Opus 5.5. 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.
Other skills, from other repositories
plur-create-engrams
Create or improve PLUR engrams from conversations, documents, decisions, observations, and explicit preferences. Use for memory extraction, engram authoring, or reviewing proposed memories, including global, scoped, pinned, retrieved, and provisional knowledge. Ordinary use of existing memories does not require this…
recall
Recall this repository's OwnMem local memory before changing code, and keep it healthy. Use when a repository contains .ownmem/, when past debugging lessons could apply ("have we hit this before", "why is it done this way"), or when the user mentions ownmem, project memory, or recalling across sessions.
Effective Memory
The essential habits for an AI agent with memory — session bookends, learning triggers, verification, safety, and the operational discipline that turns raw recall into compounding intelligence. Keyword-matched after installation.
init
Install or update OwnMem in the current repository. Use when the user asks to set up OwnMem, add local project memory for coding agents, or refresh an existing OwnMem installation after a version bump.
ori-memory
Persistent agent memory with learning retrieval. Knowledge graph on markdown files — capture insights, decisions, research, and learnings during work, then retrieve them weeks or months later. Use when knowledge is too valuable to lose but too much to inject into every prompt.
honcho-integration
Integrate Honcho memory into existing Python or TypeScript codebases. Use when adding Honcho SDK, setting up peers, configuring sessions, and accessing Honcho's representation.
