## Trust

- hygiene: 100
- liveness: 100
- freshness: 65

- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: meet (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); spark (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); play (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 1,323 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 3, about 1,323 tokens to load them all
- tool set hash: cfc497b2cc63e07b04d1bcfa45a8d24d
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.pscale-commons/pscale-biome.svg)](https://protogrid.dev/servers/io.github.pscale-commons/pscale-biome)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (3)

- `meet`: 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.
- `play`: 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.
- `spark`: 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.
