A read-only link to a saved personal summary from Mosaic, a guided app where the owner records information about themselves. The agent can read the summary from the owner’s private context.

In plain words
What is it for?
Use it when the owner asks what Mosaic says about them or what summary Mosaic has saved.
Why use it?
It lets the agent use the owner’s saved notes without treating those notes as instructions or changing them.

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

mosaic 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.

How it starts

The opening of the file, as written. The whole thing — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Mosaic (beta)

Mosaic is a guided page in the Agent Village app. The owner answers and adds things there, and Mosaic gets to know them, matches them with other residents who did Mosaic, and writes a private pair page for each match ("you two"). Use this skill when the owner asks about their Mosaic, their matches, who they should meet or build with, their team, or anything across their pair pages.

Everything here is about the owner only, in the owner's private conversation. Never use it in a group, from cron, or for another person.

Their matches and pair pages

Call the native village tool with operation: "mini-app.read", appId: "mosaic", one tool and its arguments:

Owner asks tool arguments
"Who are my top 5 matches?", "who should I meet?" top_matches {} (or {"n": 3}, 1 to 10)
"Who should I build something with?", "best collaborators" collaborators {} (or {"n": 3})
"What's my team?", "who would I make something with as a group?" team {}
Any open question across their matches: "who do I have the most unexpected overlaps with?", "who else loves jazz?", "who could I cook with?" pair_pages {}

For example:

{"operation":"mini-app.read","appId":"mosaic","tool":"top_matches","arguments":{}}

The answer is in result:

  • available: false: reason not_in_mosaic means the owner has not done Mosaic yet (or has no animal yet); not_ready means matching is not on yet; not_open means Mosaic is not open for them yet. Say so plainly and point them to Mosaic in the Agent Village app. Never guess matches.
  • During a withdrawal hold the read answers available: false with reason withdrawal_hold: say so, and that they can try again later.
  • people (best first): each has name, animal, rank (1 is their best match), why (one reason line), link (their private pair page), and page when it is written: headline, could (something they could do together), overlaps (each with area, title, what you (the owner) and them (the other person) said), fits, differ, ideas. page: null means the page is not written yet; opening the link queues it.
  • team: members (each with you true for the owner and brings, the skills they bring), covered and open (what the team has and still lacks). null means no team for them.
  • pair_pages also gives of: how many people are in their circle, so you can say how many pages you read (only written pages come back).

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.
