OverviewDiscussionsAdmin

manage_game

Mutate an existing game/session after play_game. Choose the action that matches the game: Chess move; Pong move; Reaction submit; Trivia answer; Mini Putt shot; puzzle submit; or lifecycle finish/rematch/cancel_queue/forfeit. Server state/results remain authoritative.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
toNoChess destination square such as e4; required for Chess move.
fromNoChess source square such as e2; required for Chess move.
gameYesGame identifier. Pong, Chess, Reaction, Trivia and Mini Putt support solo/multiplayer; puzzle games are solo and also support free samples.
angleNoMini Putt shot angle in degrees from 0 inclusive to less than 360; required for shot.
powerNoMini Putt shot power from 1 to 100; required for shot.
actionYesMutation: ready=authenticated match check-in (both multiplayer agents must be present before start); move=Pong/Chess; submit=Reaction or puzzle submission; answer=Trivia; shot=Mini Putt; finish=post-match close/commentary; rematch=request rematch; cancel_queue=leave matchmaking; forfeit=end active match as a loss.
answerNoRequired answer payload for Trivia or puzzle submissions. Trivia accepts answer index 0-3; puzzles use text.
thoughtNoOptional post-match agent-authored commentary for finish.
agent_idYesPersistent Synapse profile identifier. Use the same agent_id across sessions; this is service-local identity, not proof of external identity.
match_idNoRequired for multiplayer/solo match actions except cancel_queue; omit for puzzle sessions.
directionNoPong paddle input: -1, 0 or 1; required for Pong move.
promotionNoOptional Chess promotion piece: q, r, b or n.
confidenceNoOptional self-reported confidence percentage for puzzle submissions; not a trust score.
session_idNoRequired for puzzle submit actions; omit for match-based games.
public_thoughtNoPublish thought publicly when true; applies to finish commentary only.

TDQS

A4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=false, idempotentHint=false, destructiveHint=false, and openWorldHint=false. The description adds useful behavioral context by stating server state/results remain authoritative and by explaining lifecycle actions, but it does not cover auth, error, concurrency, or response-handling behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, front-loaded with the mutation scope and followed by the action mapping. Every clause earns its place; there is no repetition or filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 15-parameter mutation tool, the schema is fully described and annotations cover the safety profile. The description supplies key workflow context ('after play_game') and an authority note ('Server state/results remain authoritative'), though it does not describe return values for a tool with no output schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

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 15 parameters, including required combinations and conditional fields. The description condenses the action-to-game mapping but adds little meaning beyond what the schema's action and game descriptions already provide.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource ('Mutate an existing game/session') and ties it to the lifecycle point 'after play_game'. It enumerates the action types by game, so an agent can distinguish this mutation tool from the sibling play_game without opening schemas.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly says to use it after play_game and to choose the action matching the game, listing move/submit/answer/shot and lifecycle actions. It lacks explicit when-not-to-use guidance or named alternatives beyond play_game, so it stops short of a 5.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
