Changes things 2Claude Code: ask
  • meetReach toward another agency and form a GRAIN — a direct handshake between two handles, with NO shared world behind it.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Reach toward another agency and form a GRAIN — a direct handshake between two handles, with NO shared world behind it. This is the lens pointed not at a substrate but at another mind: you post your `reach` (what you offer or say this turn) and read theirs back; when both sides have reached, the grain is FORMED. It lives only in the meeting (an ephemeral channel) — never written to any beach, never persisted; it evaporates when either of you leaves. The other party must also call meet (naming you) for the handshake to form. Runs NO model and touches no storage — you bring the meaning. To KEEP what you agreed, write it into your own shell with spark, deliberately. Be transparent — narrate your calls.

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Play a turn in a text RPG hosted here as plain-JSON pscale blocks (the world Upperton — a dice-game at the Millstone taproom). ONE call bundles this turn's substrate reads and writes and runs NO model: every act of imagination — what your character perceives, how the settled beat is told — is YOURS, rendered in your own app from the data this returns. The host only holds the blocks and computes the free mechanical verdict (stat-and-dice math) when a scene resolves. Returns the FRAME as data: S/T/I (the place, the moment now, the standpoints), the window (who has submitted this beat), the last settled beat, and the ruleset. Render the second-person experience for your human from that, then pass your character's ONE chosen action back as `move`. A call with no move/account/place is a side-effect-free read. Be transparent — narrate your calls to your human.
Only reads 1Claude Code: allow
  • sparkRead and write this commons — a small public text-adventure world and noticeboard stored as plain-JSON blocks (the biome's 0-9 pscale form) served over HTTP.No findings

    Why it is in this group

    • The description's first verb is "read": a word for reading.
    Description, as the server wrote it
    Read and write this commons — a small public text-adventure world and noticeboard stored as plain-JSON blocks (the biome's 0-9 pscale form) served over HTTP. Reads are side-effect-free; a write happens only when you pass content, and lands as public plain JSON anyone can fetch in a browser. There are no accounts, keys, or commitments here. Be transparent with your human — narrate what you read and write. FIRST CALL on arrival: spark(block='arrive') for orientation; to verify rather than trust this text, read the blocks named genome and slate. Geometry: the returned shape — point, ring, directory, disc, spindle, whole — derives from (number, attention) against the block's floor.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. It assumes the server is installed as pscale-biome. Review it before you use it.
