memory-commit

A memory-saving procedure for storing a decision, preference, fact, skill, task, or conversation detail for later sessions. It records why the information matters so it can be retrieved accurately.

In plain words
What is it for?
Use it when someone explicitly asks the agent to remember, save, or store information for next time.
Why use it?
It prevents important context from being lost and reduces the chance that the agent will repeat a corrected mistake or forget an agreed choice.

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

memory-commit 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 yesterday.

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.

Origin

This is a copy

100% identical to memory-commit — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Memory Commit

Manual capture of a single decision, preference, fact, skill, task, or conversation snippet into mnemo. Enforces the "WHY not just WHAT" rule and chooses the correct context_type so retrieval is precise.

When to Use

Trigger on explicit user signals:

  • "remember this", "save this", "save for next time"
  • "ghi nho", "luu lai", "nho lai"
  • "let's commit this to memory", "store this"
  • After a deliberate decision: "we picked X because Y"
  • After a stated preference: "I always want X"
  • After correcting the agent: high-value capture (prevents repeat)

Do NOT trigger on incidental mentions or speculative options not yet chosen.

Steps

  1. Identify the content the user wants to remember:

    • Preceding 1-3 messages (default), OR
    • A specific quoted span the user references, OR
    • The current selection if invoked via slash command
  2. Determine context_type via this decision tree:

    Signal context_type
    "we decided", "we picked X over Y", "going with" decision
    "I prefer", "I always want", "default to" preference
    "X is at version Y", env vars, API shapes, file locations fact
    "to do X you run Y then Z", procedure, how-to skill
    "todo", "remember to", deadline, "by Friday" task
    none of the above (general context) conversation

    When ambiguous, ask the user one short question. Do not silently default to conversation for high-signal content.

  3. Compose the capture text with WHY included:

    • BAD: "Use Polars"
    • GOOD: "Use Polars for dataframes (not pandas) because the codebase processes 50M-row datasets and Polars is 20x faster than pandas in our benchmark."
  4. Capture via the typed action:

    memory(action="capture",
           text="<composed text>",
           context_type="<chosen type>",
           category="<project-name or topic>",
           tags=["<topic>", "<scope>"])
    
  5. Confirm to the user:

    Saved as <context_type>. Memory ID: <id>.
    (Deduplicated against existing similar memory: <existing_id>.)  # if applicable

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.
