Latest release: v1.0.2
Disambiguation4/5
Most tools have distinct purposes, but there is some overlap among information-gathering tools like get_state, get_unit, get_threat_map, get_tactical_summary, and get_legal_actions. However, descriptions clearly differentiate their granularity and use cases, so an agent can usually pick the right one.
Naming Consistency5/5
All tool names follow a consistent verb_noun pattern in snake_case, such as get_state, list_rooms, create_room, attack, heal. Only 'whoami' deviates slightly but is still clear. No mixing of styles.
Tool Count4/5
With 39 tools, the set is large but justified by the complexity of the game (room management, unit actions, multiple state queries, replays, leaderboards, coaching). It feels slightly heavy, but each tool serves a specific need.
Completeness5/5
The tool set covers the full game lifecycle: lobby (list/create/join rooms, set metadata), pre-game (ready, config), in-game (move, attack, heal, wait, end turn, concede), state inspection (state, unit, threat, history, telemetry), and post-game (replay, leaderboard, reporting). No obvious gaps.
Average 4.2/5 across 39 of 39 tools scored. Lowest: 2.8/5.

How is the quality score calculated?

The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).

Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.

Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).

Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.

Tool Scores

Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description reveals that the tool may call _maybe_promote_on_deadline, which 'reads+mutates state under the same critical section,' implying potential side effects beyond a pure read. However, given no annotations, it partially compensates for missing behavioral disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness2/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is verbose with implementation details about locking that are not essential for tool selection. The first sentence is clear, but the rest is overly technical for an AI agent's decision-making.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Lacks output format, error conditions, and usage context. The implementation details do not compensate for the missing output schema and parameter descriptions, leaving the tool incomplete from an agent's perspective.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0% and the description does not explain the connection_id parameter, providing no value beyond the schema's title.
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?
The description clearly states the tool shows 'the caller's current room, seats, readiness, and countdown,' which is specific and distinguishes it from sibling tools like get_state or get_history.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus siblings. The description focuses on internal locking rather than contextual usage.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Despite no annotations, the description discloses key behaviors: it writes a field without locks for performance, logs at INFO level, and includes timing. This provides good insight into side effects and logging behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness2/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is verbose with implementation details (e.g., GIL-atomic store, locking trade-offs) that are not essential for tool selection and could be omitted or summarized.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers return value and logging behavior, but omits error handling, prerequisites, and more detail on the return format. It is adequate but not thorough.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has one required parameter 'connection_id', but the description does not clarify its meaning or usage. With 0% schema description coverage, the description fails to compensate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The first sentence clearly states the tool's purpose: 'Lightweight liveness ping. Returns server time in seconds.' This is specific and distinguishes it from sibling tools, though no explicit comparison is made.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description mentions it fires every ~10s per connection and is used for monitoring, but does not explicitly state when an agent should invoke it or when alternatives are preferable.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits. It explains the internal locking mechanism for consistency and mentions that FINISHED rooms are excluded. However, it doesn't specify whether the operation is read-only, any side effects, or performance implications.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is mostly concise with a clear front-loaded purpose statement. However, the technical block about locking is somewhat verbose and may not be essential for the agent's decision-making, adding some unnecessary length.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool lacks an output schema, but the description does not describe the return format (e.g., list of room IDs or objects). It also introduces the term 'post-anonymous state' without explanation, leaving knowledge gaps for the agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has one required parameter (connection_id) with no description. The tool description provides no explanation of this parameter, leaving the agent without guidance on what connection_id means or how to obtain it.
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?
The description clearly states the tool lists rooms that are currently open, using the verb 'list' and resource 'rooms'. It distinguishes from siblings like create_room or join_room by focusing on listing. The qualifier 'currently open' and the exclusion of FINISHED rooms further clarify scope.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description mentions 'Available in any post-anonymous state', providing some context on when to use it. However, it does not explicitly say when not to use it compared to alternatives like get_room_state or preview_room, nor does it mention any prerequisites beyond connection_id.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Given no annotations, the description discloses important behavioral information: timing is logged, it hits SQLite with a non-trivial aggregation, and it has been implicated in transport hangs when slow. This adds transparency beyond the schema.
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?
Three well-structured paragraphs with front-loaded purpose, followed by key details and a performance warning. Every sentence adds value with no redundancy or extraneous content.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers return fields and performance impact, but omits explanation of the sole parameter (connection_id) and lacks any mention of error handling or empty results. Without an output schema, the return description is helpful but not fully complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has one required parameter (connection_id) with 0% description coverage, and the description does not mention this parameter at all. The agent receives no help understanding what connection_id represents or how to use it.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Return aggregated leaderboard stats per model' and details the fields and sorting, but does not explicitly distinguish from sibling stat tools like get_model_details or get_match_telemetry.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives, nor any prerequisites or caveats for appropriate usage. The description only states what it does, not when it should be invoked.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Despite no annotations, the description reveals important behavioral traits: it creates a game, uses a state lock to prevent duplicate creation, and expects a second connection to join. This is transparent about the locking mechanism and the requirement for a second participant.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise and well-structured, including a separate section for the locking mechanism. It avoids unnecessary details and is easy to read.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the lack of annotations and output schema, and the two parameters with no description coverage, the description is incomplete. It does not explain parameter roles or return value, leaving gaps for an AI agent to understand proper usage.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has two parameters (connection_id, scenario) with 0% coverage in the description. The description does not explain the meaning of connection_id or scenario, nor how they affect the behavior. The schema provides basic type info, but the description adds no value beyond that.
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?
The description clearly states that the tool creates a hardcoded dev game and seats the calling connection in slot A (blue). It distinguishes from the sibling tool 'join_dev_game' by mentioning that the second connection uses that tool to take slot B.
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?
The description explains that only one dev game can exist, and a second connection must call join_dev_game to start the match. This provides clear context for when to use the tool. However, it does not explicitly state when not to use it or list alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, but description discloses mutating nature, automatic waiting of units, and immediate opponent turn start. This adds behavioral context beyond a simple 'end turn'.
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?
Four sentences, each adding value. Front-loaded with 'Mutating' to indicate side effects. No redundancy or filler.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple turn-ending action, the description covers purpose, usage, and side effects. However, the lack of parameter documentation is a significant gap, especially with no output schema to aid understanding.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The single required parameter 'connection_id' has zero schema description coverage, and the tool description does not explain its meaning, purpose, or how to obtain it. The agent is left guessing.
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?
The description uses a specific verb 'end' and resource 'turn', clearly stating the action. It distinguishes from siblings like 'wait' and 'concede' by naming the specific game action.
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 states when to call: exactly once per turn after all move/attack/heal/wait commands. Also notes error condition for wrong turn. Lacks explicit naming of alternative actions if not ready.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full burden. It explains the return content (aggregated totals, head-to-head, per-scenario breakdown) but does not disclose behavioral traits like idempotency, side effects, or required permissions. The read-only nature is implied but not explicit.
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?
The description is two short paragraphs: the first states the core purpose, the second lists content and usage. Every sentence contributes value, and no unnecessary text is present.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description partially covers return details but omits parameter explanations. It suits a drill-down stats tool but lacks completeness for data format specifics, which would help an agent interpret results.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 0% description coverage, meaning the parameter names and types are self-explanatory only by their names. The description does not add any meaning beyond the schema, leaving the agent to infer the purpose of connection_id, model, and provider.
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?
The description clearly states 'Return drill-down stats for a single model' with specific verb and resource. It lists included breakdowns (aggregated totals, head-to-head, per-scenario) and distinguishes from sibling tools like get_leaderboard and get_history.
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?
The description provides explicit usage context: 'Used by the ranking detail screen when the lobby user presses Enter on a model row.' This indicates when to invoke, but does not offer when-not-to-use or alternatives among siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description carries full weight. It details a locking protocol with three phases, side effects like flipping GameStatus and logging forfeits, and calls to _note_game_over_if_needed. This is highly transparent about the tool's behavior beyond the basic action.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is detailed but somewhat verbose with a multi-line locking protocol. It is front-loaded with the main purpose, but the technical details could be more concise. Still, it is structured with bullet points for clarity.
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?
Given no output schema, the description does not specify return values, but it thoroughly covers the side effects and locking behavior. It is complete enough for a mutation tool, though adding return info would be better.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, and the description does not explain the single parameter 'connection_id' (e.g., how to obtain it or its format). The description adds no meaning beyond the schema's name and type, which is insufficient for a required parameter.
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?
The description clearly states 'Resign the match — opponent wins immediately,' which is a specific verb-resource combination. This distinguishes concede from sibling tools like attack, move, or end_turn.
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?
The purpose is obvious: use when you want to resign. There are no explicit when-not or alternative instructions, but the context is clear enough for an agent to decide.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description fully discloses behavioral traits: state transitions, locking semantics, default for max_turns, and failure conditions. The detailed locking explanation provides agent-critical context beyond the schema.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with clear sections and front-loaded main action. It is concise but sufficiently detailed, with no wasted sentences.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 7 parameters, no output schema, and no annotations, the description covers state transitions, locking, and defaults adequately. However, it omits parameter descriptions and return value details, leaving gaps in completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, yet the description only explains the max_turns default. It does not describe connection_id, scenario, team_assignment, host_team, fog_of_war, or turn_time_limit_s. The description fails to compensate for the lack of schema-level documentation.
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?
The description clearly states the verb 'create' and the resource 'room', specifying that the caller becomes host in slot A. It distinguishes from siblings like join_room and list_rooms by detailing the state transition and failure conditions.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies the tool is for creating a room, but it does not explicitly state when to use it versus alternatives like create_dev_game or join_room. No guidance on prerequisites or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It discloses locking behavior (state_lock during resolve, file read outside state_lock, ReplayWriter lock) and explains the availability window. It does not cover potential side effects, rate limits, or error handling for invalid states.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is structured with a brief purpose statement followed by a section on availability and locking. It is longer than necessary but each part adds relevant context. No redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Covers key aspects like timing and locking, but lacks details on the response format (beyond JSONL text), error scenarios (e.g., connection not IN_GAME), and output schema. For a download tool, some of these gaps are acceptable, but overall it feels incomplete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description should compensate by explaining the connection_id parameter. However, it provides no additional meaning beyond the schema title. The parameter remains underdocumented for an AI agent.
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?
Clearly states the tool fetches a match replay as JSONL text. The verb 'Fetch' and resource 'match replay' are specific, and the format is explicitly mentioned. This distinguishes it from sibling tools like get_history (returns JSON) or get_match_telemetry (returns telemetry).
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?
Provides a clear condition for use: while the connection is IN_GAME, including after the game ends but before state is purged. This gives an important timing context. However, it does not explicitly state when not to use it (e.g., if connection is not IN_GAME) or suggest alternative tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It describes internal mechanics (walks directory, checks config.yaml) and implies read-only, non-destructive operation.
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, the first is a clear summary, the second adds implementation detail. No wasted words.
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?
Explains purpose, mechanism, and client usage. However, missing explanation of the connection_id parameter and the return format (list of strings) would improve completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The only parameter, connection_id, is required but not explained in the description. Schema description coverage is 0%, and description adds no meaning beyond the field title.
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?
The description clearly states it enumerates scenarios by walking a directory, and distinguishes from siblings like describe_scenario (detail) and get_scenario_bundle (bundle). It specifies the client use case.
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?
Gives a clear use case (populate dropdown), but lacks explicit when-not-to-use or comparison with other list-like siblings such as list_rooms.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description labels the action as 'Mutating' and explains that the value is stored server-side. However, it lacks detail on side effects, idempotency, or permission requirements. With no annotations, the description carries the full burden but is only moderately transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise with 3-4 sentences, front-loaded with the mutation indicator. Every sentence adds value, though it could be slightly tighter.
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 simple reporting tool with two parameters and no output schema, the description provides sufficient context about purpose, usage, and parameter semantics (except connection_id). The inclusion of server-side storage and visibility via get_match_telemetry adds completeness.
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?
The description explains the 'tokens' parameter as a positive integer for the token count, which adds meaning beyond the schema. However, 'connection_id' is not described, and since schema coverage is 0%, the description only partially compensates for the missing parameter documentation.
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?
Clearly states the tool reports LLM token consumption for cost tracking. The description is specific about what is reported and why, and it distinguishes itself from sibling tools like report_issue by focusing on tokens.
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 notes that the tool is called by the client harness after each turn and is not typically called by the agent itself. This provides clear guidance on when to use it, though it does not mention alternatives or when not to use it beyond self.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without annotations, the description discloses key behavioral traits: mutation, dev-only shortcut, bypass of ready-up flow, requirement for specific state, and return values (room_id, assigned slot). Missing details on possible errors or limits, but adequate for a simple tool.
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?
Three sentences, each earning its place: first sentence states mutating behavior and purpose, second states prerequisite, third states return and production alternative. Front-loaded with key keywords for quick agent scanning.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
While the description covers purpose, usage, and behavior well, it omits explanation of the input parameter `connection_id`. For a tool with one parameter and no output schema, this gap reduces completeness. The prerequisite mentions state but doesn't clarify the parameter's role.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has one parameter `connection_id` with 0% coverage in description. The description provides no explanation of what connection_id is or how to obtain it. With low schema coverage, the description must compensate but fails entirely, leaving the agent uninformed about the sole required input.
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?
The description clearly states the verb 'join' and resource 'dev game', specifying it's a development-only shortcut that joins the first available room as red player and starts the match. It distinguishes from sibling tools like join_room by highlighting the bypass of normal ready-up flow and production use case.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides explicit usage context: development-only shortcut with prerequisite (state=in_lobby, call set_player_metadata first). Also gives clear alternative for production: use join_room + set_ready instead. This helps the agent decide when to invoke this tool vs alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Discloses key behaviors: only non-None fields updated, ready flags reset on any change, atomic mutation under state_lock, and failure conditions outside pre-game states. No annotations, so description carries full burden and does well.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Structured with clear sections and about 6 sentences. Could be slightly tighter, but overall well-organized and not overly verbose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite good usage and transparency, missing parameter explanations and no output schema make it incomplete for an agent to correctly invoke the tool, especially with 7 parameters.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has zero descriptions (0% coverage) and description does not explain individual parameters like scenario, team_assignment, etc. It only states that only passed (non-None) fields are updated, leaving parameter meaning unclear.
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?
Clearly states 'tweak room config while still in the lobby' with specific verb 'tweak' and resource 'room config', distinguishing it from siblings like create_room, join_room, preview_room, and set_ready.
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?
Specifies 'Host-only' and 'while still in the lobby', and notes it fails outside pre-game states (COUNTING_DOWN, IN_GAME, FINISHED). However, it does not explicitly state when not to use or suggest alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, but description discloses atomicity via state_lock and the effect (connection returns to IN_LOBBY). Could mention reversibility or side effects.
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?
Concise, structured with clear sections. Every sentence adds value. No extraneous words.
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?
Covers prerequisites (host-only, pre-game), effect, and atomicity. Missing mention of whether action is reversible or how to get connection_id.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage 0%, description does not explain connection_id parameter beyond its name. Agent may not know how to obtain it.
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?
Clearly states verb 'kick', resource 'joiner (slot B)', and host-only constraint. Distinct from siblings like leave_room and join_room.
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 states pre-game only (WAITING_FOR_PLAYERS, WAITING_READY) and cannot use during gameplay. However, does not compare to alternatives or indicate when not to use.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
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 critical behavioral traits: auto-concede for mid-match, locking protocol with three phases, and transition to FINISHED state. The internal implementation details (variable names, lock order) are transparent, providing a complete picture of side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is front-loaded with the core purpose in the first sentence, but includes several paragraphs of internal locking implementation that may be excessive for an agent. While structured with headings, it lacks conciseness; the locking details could be summarized without sacrificing essential transparency.
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?
Given no output schema and no annotations, the description explains the tool's lifecycle: returning to lobby, auto-concede, state transitions, and locking. However, it omits description of the single parameter and what the tool returns (if anything). This gap reduces completeness but overall coverage of behavior and side effects is strong.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 0% description coverage for the single required parameter 'connection_id'. The description does not explain the parameter's meaning beyond the name, nor does it provide any guidance on its format or usage. Given the low coverage, the description should compensate but fails to add value.
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?
The description clearly states the tool's purpose: 'Vacate this connection's seat and return the caller to the lobby.' It also specifies accepted states (IN_ROOM, IN_GAME) and distinguishes from siblings like 'concede' by noting auto-concede behavior. The verb 'vacate' and resource 'connection's seat' are specific, making the purpose unambiguous.
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?
The description explicitly states when to use the tool: from IN_ROOM (pre-game) or IN_GAME (mid-match or post-match). It explains the behavioral difference for mid-match departures (auto-concede) versus post-match (normal lobby return). However, it does not explicitly contrast with alternatives like 'concede' or state when not to use it, which would improve guidelines.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Declares 'Read-only' upfront and mentions prerequisite 'Requires set_player_metadata.' This covers key behavioral traits despite no annotations. However, it does not mention potential errors or rate limits.
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?
Description is concise, front-loaded with 'Read-only,' and structured logically. Every sentence adds value without redundancy.
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 read-only tool with no output schema, it adequately describes return values (scenario, layout, occupancy, config) and usage context. Missing error conditions but otherwise complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so description must compensate. It explains room_id ('string identifier from list_rooms') but gives no information about connection_id. Only partial parameter meaning added.
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?
The description clearly specifies 'Read-only. Return a room's current state' and enumerates specific components (scenario name, board layout, etc.). It distinguishes itself from siblings by stating usage for previewing before joining, which is distinct from other tools like get_room_state.
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 states use cases: 'inspect a room before joining with join_room' and 'check ready status while waiting for the match to start.' It also identifies the source for room_id. While it doesn't list when not to use, the context is clear enough.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description fully explains the tool's behavior: it persists reports to three sinks (replay, log, jsonl), handles category validation, and describes locking mechanics. This provides sufficient transparency about side effects and conditions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with clear sections (purpose, sinks, categories, availability, locking). It is front-loaded with the main purpose. While slightly verbose, every sentence adds value, and the structure aids readability.
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?
Given the lack of annotations and output schema, the description provides comprehensive context: persistence sinks, category semantics, availability, and locking. It covers most behavioral aspects, though it does not detail return values or error handling for invalid categories, which would be helpful.
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?
The input schema has 0% description coverage, so the description must compensate. It thoroughly explains the 'category' parameter with allowed values and usage, and implies 'summary' as a brief description. However, 'connection_id' is not explicitly described, and 'details' is only mentioned as optional. This leaves some ambiguity for the agent.
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?
The description clearly states that the tool records agent-observed problems like bugs, confusion, or suggestions. It provides specific examples and distinguishes between similar categories such as 'imbalance' and 'scenario_issue', making it distinct from sibling tools like 'record_thought' or 'report_tokens'.
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?
The description details when to use the tool (when expectations are violated) and provides specific category usage (e.g., 'imbalance' for lopsided scenarios). It also clarifies availability ('Always available') but does not explicitly mention alternatives or when not to use it, which is a minor gap.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It discloses that the read is atomic under a lock to prevent torn snapshots. This is a useful behavioral detail. However, it does not mention idempotency or whether the tool is read-only (implied but not explicit).
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?
The description is two sentences that efficiently convey the purpose and a key behavioral detail. No unnecessary words or repetition.
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?
Given the simplicity of the tool (one required parameter, no output schema), the description provides essential details. It could be slightly more complete by specifying what 'current state' includes (e.g., game state, connection status), but the atomicity note adds value. The sibling tools list does not indicate a need for more.
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?
The input schema has one required parameter 'connection_id' (string). The description does not explain this parameter beyond what the schema provides (title 'Connection Id'). Since schema coverage is 0%, more guidance would be helpful, but the parameter is straightforward from its name.
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?
The description clearly states the tool returns 'this connection's current state + player metadata', using a specific verb ('Return') and identifying the resource. This distinguishes it from siblings like 'get_state' which may return general state, and the name 'whoami' is self-explanatory.
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?
The description explains the atomic read behavior, implying it is safe for consistent reads during concurrent updates. However, it does not explicitly state when to use this tool over alternatives like 'get_state' or 'get_match_telemetry', though the name suggests it is for the current connection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It declares 'Read-only' indicating no mutations, and describes the returned data (actions, units, targets, turn number). Could add more details like data freshness or pagination limits, but sufficient for a read-only tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Three sentences efficiently convey purpose, usage, and param detail. No fluff, but could be slightly better structured with line breaks for readability.
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?
With 2 params and no output schema, description covers purpose, usage guidelines, param details, and sibling differentiation. Lacks explicit return format, but context is adequate for agent to use the tool.
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 0%, so description compensates partially. Explains 'last_n' with default and max values, but does not describe 'connection_id'. Adds value for one parameter but lacks full coverage.
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?
Description clearly states the verb 'return', the resource 'most recent game actions', and includes specific action types (moves, attacks, etc.). It distinguishes from sibling 'get_match_telemetry' by focusing on recent turn-by-turn actions.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicit guidance: 'Use this at turn start to understand what the opponent did last turn' and 'For aggregate match statistics use get_match_telemetry instead.' Provides clear when-to-use and when-not-to-use with a named alternative.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Although no annotations exist, the description declares 'Read-only' and notes availability constraints ('during and after a match'), providing key behavioral context. It lacks detail on error handling or authorization, but for a simple stats tool this is sufficient.
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?
The description is three sentences: first states core function, second adds usage context, third differentiates from a sibling. It is front-loaded and every sentence adds value.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description specifies when to use ('Available during and after a match', 'post-game analysis or mid-game cost monitoring') and explicitly states the alternative: 'For game-state history use get_history instead.'
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, but description discloses it's a read-only digest with predicted outcomes, threats, and pending actions. Could mention it's non-destructive, but sufficient context.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without annotations, the description fully discloses behavioral traits: it is mutating, requires being in a room, triggers a countdown when both ready, and cancels on unready/leave/disconnect. No contradictions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?

Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description fully discloses the mutating behavior, failure conditions (room full, doesn't exist, already in room), and return values (room_id and slot). There is no contradiction with structured fields.
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?
The description is concise, front-loaded with 'Mutating', and each sentence serves a specific purpose: precondition, parameter source, return, failure cases, and next steps. No extraneous information.
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?
Given no annotations, no output schema, and 2 parameters, the description covers most essential behavioral details. The only gap is the lack of explanation for connection_id, but overall it provides enough context for correct tool invocation.
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?
The input schema has 2 parameters with 0% schema coverage. The description explains room_id as 'the room's string identifier from list_rooms' but does not explain connection_id, leaving the agent to infer its purpose. This partially adds value over the schema.
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?
The description explicitly states 'Join an existing room' using a specific verb and resource. It distinguishes from sibling tools like 'create_room', 'leave_room', and 'list_rooms' by providing context about the room lifecycle and preconditions.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description clearly specifies when to use this tool: requires state=in_lobby and set_player_metadata first. It also gives explicit guidance on next steps (call set_ready) and alternatives for leaving (use leave_room).
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description fully discloses key behaviors: it mutates state, queues the message for the next turn, the agent may ignore it, and messages are not visible to the opposing team. This provides sufficient transparency for an AI agent to understand the tool's effects.
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?

Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has no parameter descriptions (0% coverage), so the description adds crucial meaning: 'team' must be 'blue' or 'red', 'text' is a coaching instruction. 'connection_id' is implied to identify the human coach connection. While 'connection_id' is not explicitly explained, the context 'Coach-only tool' gives enough hint.
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?
The description specifies the exact action ('queue a natural-language message') and the resource ('team's AI agent'). It also states the delivery timing ('at the start of its next turn'). This clearly distinguishes it from sibling tools like 'attack' or 'move', which are direct game actions.
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?
The description explicitly restricts usage to human coach connections and states that AI agent connections receive an error. It also specifies that team must be 'blue' or 'red'. However, it does not explicitly state when not to use this tool or suggest alternatives, though no siblings serve a similar purpose.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
