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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00022 | $0.00437 |
| Opus 5.5 | $0.00009 | $0.00175 |
| Sonnet 5.5 | $0.00004 | $0.00087 |
| Haiku 4.5 | $0.00002 | $0.00044 |
Grade A, and why
mama-install scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Install MAMA OS
You install; the owner decides every choice and types every secret.
-
Install the local server and read its commands:
npm i -g @jungjaehoon/mama-os mama --help -
Setup is
mama init. It asks for tokens at hidden prompts, so the owner runs it in their own terminal. Never ask for a token, key or password in the conversation. Before they start, walk them through what it asks, following the owner setup guide; itsnode packages/standalone/dist/cli/index.jsform is for a source checkout, and afternpm i -gthe command ismama. -
One choice sends owner text out:
mama initasks whether to use Jev (TypeSafe). With it, the owner agent can judge many messages or items without reading them all; the text in those calls goes to the Jev service. Explain this and let the owner choose. MAMA works the same without it. If they choose it, they get a key from TypeSafe (https://docs.typesafe.ai) and type it at the hidden prompt; it is stored in~/.mama/jev-key(0600). -
Have the owner sign in the backend before
mama init(claude auth login, or for CodexCODEX_HOME="$HOME/.mama/.codex" codex login); init checks it, then starts MAMA itself and says when it is running.mama statusshows it afterwards.
Installation is complete only when the owner sends a message to their bot and MAMA answers. Files on disk or a running daemon are not the end.
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.

mama-install is a skill published in the GitHub repository jungjaehoon-lifegamez/MAMA (14 stars, last pushed 10d ago), licensed MIT. It adds 22 tokens to every session and 437 once invoked, about $0.0001 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.

memai-maintenance
Orchestrator of the MemAI MAINTENANCE pass (long-term agent memory). Runs [[memai-checkpoints]], [[memai-distill]], [[memai-confidence]] and [[memai-link]] as one curation pass, owns what none of them covers — the DOMAIN TREE (nested paths, cross-listing, casing), the DIAGRAMS and the store's DECAY (reviewafter) — and…
memai-confidence
Verify a MemAI memory's claims against live facts and set its confidence (unverified | confirmed | contradicted). Checks the anchors a scan already extracted — file:line, symbol, table/column, domain, URL — against today's source, promotes or demotes each memory, stages a reword for a detail that drifted, and pushes…
memai-checkpoints
The lifecycle of MemAI CHECKPOINTS: deciding which bearing is still current and which one is superseded, archiving the checkpoint of work that is closed or an intra-session trail that a newer one already covers, keeping the single bearing a live effort still needs, correcting a fact in a kept checkpoint that has gone…
memai-distill
Distill and MOVE knowledge between MemAI types: pull what is durable out of one checkpoint (or several) into a note/reasoning/antipattern, change a memory's type (checkpoint→note when the content is timeless), and merge near-duplicates. Use when the user asks to "distill memory", "turn a checkpoint into a note", "move…
memai-link
Stitch the MemAI relations GRAPH: typed edges between memories (supersedes / relatesto / contradicts / linksto), turning [[wikilinks]] written in a body into real edges, connecting complementary memories that share a domain, and preserving lineage (checkpoint to note, archived to successor). Uses dedupscan to find…
