Tool Definition Quality
Average 4.2/5 across 3 of 3 tools scored.
Each tool serves a clearly distinct purpose: meet for ephemeral handshake between handles, play for engaging in a specific RPG turn, and spark for reading/writing public blocks. There is no functional overlap.
All three names are single verbs, but they are not descriptive of the specific domain and do not follow a verb_noun or any other clarifying pattern. The names are short but ambiguous out of context.
With 3 tools, the set is small but minimally covers the intended interactions (peer handshake, game turns, block storage). It is on the lower end of the typical range but still reasonable for a focused server.
The tools cover basic interactions but lack explicit support for common operations like character management or world exploration beyond the specific RPG. Relying on spark for all read/write leaves gaps for more complex workflows.
Available Tools
3 toolsmeetAInspect
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.
| Name | Required | Description | Default |
|---|---|---|---|
| face | No | Your aperture in the meeting (character / author / designer / observer). Default character. | |
| with | Yes | Who you are reaching toward — their handle. They must meet you back for the grain to form. | |
| reach | No | Your offering this turn — what you say, propose, or hold out to the other. Omit to ping presence without words. | |
| handle | Yes | Who you are — your handle. |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description fully carries the burden. It explicitly states that meet runs NO model, touches no storage, is ephemeral, evaporates when either leaves, and requires mutual invocation. This is highly transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured and front-loaded with the core purpose. It is somewhat lengthy due to explanatory detail, but each sentence adds value. Slight redundancy (e.g., 'evaporates when either of you leaves' after 'never persisted') but not detrimental.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's moderate complexity and lack of output schema, the description covers all essential aspects: how the handshake works, the need for mutual calls, the ephemeral nature, and the distinction from spark. It is sufficiently complete for an agent to use correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents all parameters. The description adds some context (e.g., 'face' as aperture, 'reach' as offering), but it mostly rephrases the schema descriptions without significant added value. Baseline of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: 'Reach toward another agency and form a GRAIN — a direct handshake between two handles'. It distinguishes itself from siblings by mentioning that to keep agreements, use 'spark', implying meet is ephemeral.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides clear context: the other party must also call meet, and the grain is ephemeral. It tells when to use it (to communicate with another agency) and what to do instead for persistence (use spark). However, it does not explicitly mention when not to use it or provide alternatives like 'play'.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
playAInspect
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.
| Name | Required | Description | Default |
|---|---|---|---|
| face | No | Your aperture: character (default) / author / designer / observer. Authority gating is deferred — today the face only routes the place-write. | |
| move | No | Your character's ONE intention this beat, first person ('I ...'). Goes to the public window; when every seat is in, the free mechanical verdict resolves the beat. Omit to read without acting. | |
| place | No | Your character's own rendition of this place (face=character → your version), or with face=author the woven canonical voicing. Optional; builds the lived-in world. | |
| rules | No | The ruleset block. Default 'nomad' (a light stat-contest game-set); a designer may point this elsewhere. | |
| where | No | The scene address as a pscale walk (e.g. '1121' for the taproom). Omit to use your located standing. | |
| world | No | The cosmology to play in. Currently 'upperton' (the only world seeded here); selects its S/T/I blocks. | |
| handle | Yes | Your seat — the character you inhabit (e.g. merchant, watcher, keeper, regular). | |
| account | No | Your app's rendition of the PRIOR turn (the echo you showed your human) — appended to your character's own lossless history. Omit on the first turn. |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It discloses that the tool bundles reads and writes, runs no model, and that mechanical verdicts are computed off-host. It also notes side-effect-free reads. Good transparency for the context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is lengthy and mixes lore, instructions, and technical details. While front-loaded with purpose, it could be more structured and concise. Some sentences are verbose and less essential.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity (8 parameters, no output schema), the description provides a comprehensive picture of the tool's role, return frame (S/T/I, window, last beat, ruleset), and mechanics. It is largely complete for the RPG context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, but the description adds significant context beyond parameter descriptions. It explains the role of each parameter in the game (e.g., move is the character's intention, account is prior turn rendition). This enriches understanding for the AI agent.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool is for playing a turn in a text RPG hosted as plain-JSON pscale blocks. It specifies the context (Upperton dice-game at Millstone) and that it returns frame data. However, it does not explicitly differentiate from sibling tools (meet, spark), so not a 5.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explains the game loop: call returns frame, then user submits move. It mentions 'side-effect-free read' when no parameters. But it does not provide explicit when-to-use vs alternatives or exclusions, leaving usage somewhat implied.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
sparkAInspect
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.
| Name | Required | Description | Default |
|---|---|---|---|
| block | Yes | Block name, e.g. arrive, lighthouse, slate, genome, marks. | |
| proof | No | Proof you hold your shell, when the membrane requires it. handle-mode needs none; lock-mode (later) takes your passphrase here. | |
| handle | No | Your located identity, when the identity membrane is on: the handle of your shell. Reads need none; a write must be signed by a handle that holds a registered shell (write 'shell-<handle>' to register). Ignored when the membrane is off. | |
| number | No | Pscale address — one decimal, pinned to the floor (e.g. '42.1'). Omit for disc/whole. | |
| content | No | Payload for writes; omit to read. | |
| attention | No | Pscale integer — the scope. Omit with a number for the spindle; omit both for the whole block. |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description fully discloses behavioral traits: reads are side-effect-free, writes only when 'content' is passed and result in public plain JSON, and there are 'no accounts, keys, or commitments'. It also explains authentication via 'handle' and 'proof' parameters.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is informative but somewhat lengthy, with multiple clauses. It is front-loaded with the core purpose and key actions, though some phrases (e.g., 'Be transparent with your human') add ethical guidance rather than technical clarity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given complexity (6 params, no output schema), the description explains the overall context and geometry but does not specify return value format or error conditions. The geometry description is helpful but incomplete for an agent to fully anticipate outputs.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% (baseline 3). The description adds value by explaining the geometry derivation from 'number' and 'attention', and providing context for 'block' values. This exceeds mere schema repetition.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: 'Read and write this commons — a small public text-adventure world and noticeboard stored as plain-JSON blocks'. It provides a specific verb (read/write) and resource (commons), and distinguishes from siblings by describing a unique interaction model.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives explicit usage guidance: 'FIRST CALL on arrival: spark(block='arrive') for orientation' and suggests verifying by reading 'genome' and 'slate'. It implies when to read vs write but does not contrast with sibling tools 'meet' and 'play'.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
