In plain words

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

memorix-reasoning 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 8d 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.

What it actually says

Memorix Reasoning

Use reasoning memory for why a decision was made. Use ordinary memory for what happened.

Use Reasoning When

  • The answer depends on alternatives considered, constraints, expected outcomes, or accepted risks.
  • A future agent may otherwise reopen the same debate.
  • The user chose a direction and the reason matters more than the implementation details.
  • A Git Memory entry says what changed, but not why it changed.

Do Not Use Reasoning For

  • Simple progress notes.
  • Mechanical refactors with no decision.
  • Facts that belong in memorix_store as how-it-works, what-changed, or problem-solution.
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.
