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 | $0.00000 | $0.00228 |
| Opus 5 | $0.00000 | $0.00114 |
| Sonnet 5 | $0.00000 | $0.00046 |
| Haiku 4.5 | $0.00000 | $0.00023 |
Grade A, and why
prime 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 2d 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
/mneme:prime
Inject preflight context for the current task into the conversation.
Usage
/mneme:prime <task description>
The task description is free text. The longer and more specific, the better mneme can match relevant vault content.
What it does
Calls the mneme_prime MCP tool with the supplied task description.
The tool returns a markdown bundle that contains:
- The most recent session-typed vault documents.
- Vault documents whose content matches tokens in the task description.
Both selections are formatted with vault paths so you can navigate to source content directly. The bundle is truncated to fit within the configured token budget (default 4000 tokens).
When to use
- Starting a new session that picks up a long-running thread.
- Switching topics mid-session and wanting Claude oriented before the first prompt.
- Before a code review session where prior decisions matter.

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.
