Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00055 | $0.00485 |
| Opus 5 | $0.00028 | $0.00243 |
| Sonnet 5 | $0.00011 | $0.00097 |
| Haiku 4.5 | $0.00006 | $0.00049 |
Grade A, and why
new scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Create a knowledge plugin the router can actually use. The scope statement is the routing prompt — invest in it.
- Interview the user briefly (2–4 questions): What products/systems/processes does this plugin cover? What explicitly does NOT belong? Who maintains it (owner/team)? How sensitive is it (
public,internal,restricted)? Ask whether anyone outside the team will INSTALL it. If not — a team's own knowledge, an internal ops commons — offer--no-plugin: same layout, same skills, same facts, same gates, minus the plugin manifests and the release workflow. It stays fully lintable, classifiable and searchable; it just is not published to a marketplace. Do not offer it as "lighter" — nothing is missing except distribution, andmneme adopt <name> --as-pluginadds that later without moving any knowledge. - Compose a 2–5 sentence scope statement from their answers — specific names, not generalities.
- Run
mneme new <name> --description "<scope statement>" --owner "<owner>" --sensitivity <s>(binary at"$CLAUDE_PLUGIN_ROOT/bin/mneme"when installed, elsebin/mneme), adding--no-pluginif that is what they chose. - Open the generated
MNEME.md, refine the "What belongs here / What does NOT belong here" sections with the interview specifics, and show the user the final scope statement. - Report the repo path, and relay the command's own
no-plugin:lines verbatim when they appear. For a plugin, remind them: add a git remote and it distributes itself — consumers run onemarketplace addand inherit every merged update, and harvested knowledge arrives as a pull request off amneme/harvest-*branch. Until there is a remote, harvests stay on that local branch for them to merge; mneme never commits tomaineither way.
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.

new is a skill published in the GitHub repository rhoulihan/mneme (6 stars, last pushed 13d ago), licensed Apache-2.0. It adds 55 tokens to every session and 485 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 2026-08-31.
