Server Quality Checklist

Profile completionA complete profile improves this server's visibility in search results.

Latest release: v0.3.1
Disambiguation5/5
Each tool targets a specific function within its sport (e.g., fantasy team building, live odds, match prediction, driver analysis). Despite the large number, descriptions clearly differentiate purposes, and no two tools appear to do the same thing.
Naming Consistency5/5
All tools follow a consistent snake_case pattern with a sport prefix (e.g., cricket_build_dream11_team, f1_get_drivers, football_find_value_bets). Verb_noun structure is maintained throughout, making the naming predictable.
Tool Count4/5
With 44 tools across three sports plus cross-sport functionality, the count is slightly high but justified by the breadth of coverage. The scope is well-defined for a multi-sport analytics server, and each tool serves a distinct purpose without overwhelming redundancy.
Completeness5/5
The tool set covers the major aspects of each sport: cricket (fantasy, odds, match data, player stats), F1 (drivers, sessions, race analysis, weather, strategy), and football (match prediction, tournament simulation, odds, standings). No obvious gaps are present for the stated domain.
Average 4.2/5 across 44 of 44 tools scored. Lowest: 3.5/5.

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

Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, so the tool is safe and idempotent. The description adds value by specifying the return structure (has_rain, avg_track_temp_c, compound_recommendation, recommendation) and noting that meta.estimated is true, indicating the output is a model estimate. This enhances transparency beyond the annotations.
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 two main sentences and a structured Args/Returns block. It is front-loaded with the main purpose. The Returns section provides valuable output details. However, the Args section repeats the schema description, which is slightly redundant but not harmful.
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 tool's focus on weather-driven strategy recommendations, the description covers the input (session_key), the analysis performed, and the output structure. However, it does not explain edge cases, such as sessions with no weather data, or how the recommendation is derived. With rich annotations and a single parameter, the description is mostly complete for a tool of this complexity.
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 single parameter session_key is described in both the schema and the tool description identically as 'OpenF1 session identifier.' Since schema coverage is 100%, the description adds no new semantic information about the parameter. Baseline score of 3 is appropriate.
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 it analyzes weather data and recommends compound or pit-window adjustments, which is specific and action-oriented. It distinguishes itself from siblings like f1_get_weather (which only provides weather data) and f1_predict_pit_strategy (which may not incorporate weather as directly), though it could be more explicit about the unique value proposition.
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 provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, when not to use it, or comparison with similar tools like f1_undercut_window or f1_predict_pit_strategy. This lack of usage context reduces its helpfulness for an agent deciding between 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?
Annotations already indicate readOnly, idempotent, non-destructive. The description adds that the output has the same shape as football_build_accumulator with a sport field per leg, and meta.estimated is true, which enriches behavioral understanding beyond bare annotations.
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 the purpose, and each sentence (purpose line, args, returns) serves a clear function with 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?
Given the two simple parameters, complete schema, and rich annotations, the description provides sufficient context including output shape and meta flag. It could mention supported sports explicitly but is otherwise adequate.
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?
Input schema covers 100% of parameters with descriptions. The description repeats default values and ranges but does not add new semantic meaning beyond what the schema already provides.
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 the tool models joint probability across football and cricket. The cross-sport aspect distinguishes it from single-sport siblings like football_build_accumulator, though it does not explicitly contrast them.
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 use for multi-sport accumulators (football and cricket), but provides no explicit guidance on when to use this tool vs alternatives like football_build_accumulator or when not to use it.
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?
Annotations already indicate a safe, read-only operation. The description adds useful behavioral context, such as fallback to group schedule when live providers are unavailable and return structure details.
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 includes separate Args and Returns sections, making it structured but slightly verbose. It could be more concise while retaining key 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 the annotations and output schema presence, the description adequately covers parameters, pagination, and data source behavior. It is largely complete for understanding 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 coverage is 100%, and the description essentially repeats the parameter meaning. No additional semantic value beyond the schema is provided.
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 World Cup 2026 fixtures, specifying the data source (live providers or group schedule). This is distinct from sibling tools like football_get_groups or football_get_match_stats.
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 does not explicitly mention when to use this tool over alternatives or provide exclusion criteria. Usage is implied but not guided.
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?
Annotations already declare readOnlyHint, idempotentHint, and non-destructive. The description adds behavioral context: it uses squad form and player stats, and explicitly notes 'meta.estimated: true' indicating the results are estimations/probabilities. This goes beyond the annotation 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 concise with a clear purpose statement and structured Args/Returns sections. It adds necessary detail without fluff. A minor point: listing return fields may be redundant given output schema exists, but it helps quick comprehension.
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 output schema exists (context signals), the description provides a useful summary of return fields and highlights the estimated nature. It adequately covers the tool's behavior for a read-only comparison tool. Could mention pagination or limitations, but not critical.
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 coverage is 100% with descriptions for both parameters. The description essentially repeats the same param info without adding new semantics like format constraints or valid values. Baseline 3 is appropriate as schema does the heavy lifting.
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 compares two cricket teams head-to-head using squad form and player stats. It distinguishes from siblings like cricket_get_scorecard (which provides match details) and cricket_player_matchup (player vs player). The verb 'compare' is specific and resource is clear.
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 usage for comparing teams, but does not explicitly state when to use this tool over alternatives like cricket_get_scorecard or cricket_player_form_index. No exclusions or when-not-to-use guidance is provided, leaving the agent to infer context from the name and description.
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?
Annotations already indicate readOnly, idempotent, and non-destructive behavior. The description adds that the tool returns estimated averages and delta (meta.estimated: true), disclosing approximation. It also specifies the output structure (avg_s, faster_driver), which goes beyond the annotations. 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?
The description is concise: a single purpose sentence followed by Args and Returns. It is front-loaded with the key function. However, the Args section partially duplicates schema descriptions, which is slightly redundant. Still clear and efficient.
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 that an output schema exists (implied by context signals), the description does not need to detail return values. It adequately covers inputs, purpose, and estimation hint. Minor gaps: no mention of error handling or driver existence checks, but acceptable for a simple comparison 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 100%—each parameter has a clear description identical to the tool description's Args section. The description adds no new semantic value beyond what the schema provides (e.g., no ranges, examples, or constraints). Baseline 3 due to full schema 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?
The description clearly states the action ('Compare lap-time pace distribution') and the specific resource ('between two drivers in a session'). It is distinct from sibling F1 tools like 'f1_get_lap_times' (raw times) and 'f1_race_pace_compare' (possibly different scope). The verb 'Compare' precisely conveys the tool's function.
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 does not provide explicit guidance on when to use this tool versus alternatives (e.g., 'f1_race_pace_compare'). The purpose is clear, but no when-not-to-use or preferred scenarios are mentioned. Usage must be inferred from the tool name and purpose.
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?
Annotations already declare readOnlyHint, openWorldHint, idempotentHint. Description adds valuable context: 'meta.estimated: true — model output, not telemetry oracle.' This clarifies the tool returns a fitted model, not raw data.
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 (5 lines), well-structured with 'Args:' and 'Returns:' sections. Every sentence adds value; no fluff.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
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 the presence of both annotations and output schema description, the description fully explains what the tool does, its parameters, and what it returns. No gaps.
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 baseline is 3. The description repeats parameter names and types but adds no new semantic detail beyond what the schema already provides.
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 specific verb 'Fit' and identifies resource 'tyre degradation model' with clear scope 'driver + compound in session'. It distinguishes from sibling F1 tools like f1_get_lap_times which return raw data.
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 explicit guidance on when to use this tool versus alternatives. The description does not mention when not to use it or provide context for choosing among sibling 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?
Annotations already declare readOnlyHint, openWorldHint, idempotentHint. The description adds return structure (laps_to_clear, viable, marginal) and meta.estimated flag, providing extra behavioral context beyond annotations.
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?
Description is concise with a clear one-sentence purpose followed by structured args and returns. Slightly redundant due to repeating schema info, but still efficient.
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?
The description covers key purpose, parameters, and return fields. Since an output schema exists, it doesn't need to detail return values fully. Adequate for the tool's complexity.
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 coverage is 100% and description repeats parameter names/descriptions from schema without adding new meaning. Baseline 3 is appropriate.
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 estimates undercut viability for attacker against target, with specific verb 'estimate' and resource 'undercut window'. It distinguishes from siblings like f1_predict_pit_strategy and f1_tyre_degradation.

Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for undercut analysis but does not explicitly state when to use it versus alternative F1 pit strategy tools or provide exclusion criteria.
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?
Annotations already indicate read-only, idempotent, and non-destructive behavior. The description adds significant context: the data source (The Odds API), graceful degradation ('ALL_SOURCES_FAILED envelope' instead of crash), and output metadata (e.g., cache:stale adapter). This goes beyond what annotations provide.
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: purpose, source/prerequisite, parameter section, and return format. It is concise (4 sentences plus list). However, the parameter description duplicates the schema verbatim, slightly reducing efficiency. The Returns section compensates by describing output structure.
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 tool with one optional parameter, rich annotations, and an output schema (not shown but referenced), the description covers purpose, source, error handling, parameter semantics, and output structure. It does not discuss rate limits or pagination, but these are presumably handled by the output schema and annotations.
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% because the single parameter (team) has a full description in the input schema. The tool description repeats exactly the same text, adding no new semantic information. At baseline 3, no extra value is provided.
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 ('Return') and identifies the resource ('live market head-to-head odds for upcoming World Cup 2026 matches'). This clearly differentiates it from sibling tools like football_find_value_bets (value bet identification) or football_build_accumulator (accumulator building).
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 the requirement of a THEODDS_KEY and the graceful failure without it, which is useful. However, it does not explicitly guide when to use this tool versus siblings (e.g., raw odds vs. value bets) or provide when-not-to-use scenarios. The scope is limited to World Cup 2026, but no alternatives are suggested.
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?
Annotations declare readOnlyHint, idempotentHint, and non-destructive, and the description adds context: the tool uses simulation, returns probabilities, and notes meta.estimated: true. It also explains the output structure (reach_r32, etc.) and parameter clamping, going beyond the annotation cues.
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 compact with a clear Args/Returns structure, around 5 lines. It avoids excessive verbosity, though the Args section largely duplicates schema info. Slightly more conciseness could be achieved, but it is generally well-structured.
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 tool has an output schema (not displayed) and 100% schema coverage, the description adequately explains the output fields (team, reach_r32, etc.) and the simulation clamp. It does not cover simulation assumptions or error handling, but for a read-only tool with good annotations, it is sufficiently complete.
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 coverage is 100%, so baseline is 3. The description repeats parameter descriptions from the schema without adding new meaning (e.g., 'clamped to 100..20000' already in schema). No additional semantics or usage examples are given.
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 computes 'Round-by-round survival probabilities for one team in the full sim,' specifying the verb (survival probabilities) and resource (one team in a tournament). This distinguishes it from siblings like football_simulate_bracket (entire bracket) and football_match_predictor (match outcome).
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 a single team's knockout path, but it does not explicitly state when to use this tool versus alternatives such as football_simulate_bracket or football_match_predictor. No direct usage guidance or exclusions are provided.
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?
Annotations already indicate readOnlyHint, openWorldHint, idempotentHint, and destructiveHint false. The description adds return format details but does not significantly extend behavioral disclosure beyond the annotations.
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 a clear two-section format (Args, Returns). It includes necessary information without extraneous text, though the structured docblock style could be slightly more compact.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has a single parameter, comprehensive annotations, and an output schema, the description is fully adequate. It explains input, output, and behavior without gaps.
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 100% coverage with description for the venue parameter. The main description adds no additional meaning beyond what the schema provides, warranting the baseline score of 3.

Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is very concise: three lines for the overall purpose, then Args and Returns sections. Every sentence is necessary, no redundancy. The structure is clear and easy to parse.
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 tool that compares two drivers per session and returns compound-wise data, the description provides key context: it's an estimated model, not official timing. The return structure hints at the data shape. Given that an output schema exists (not shown), the description is sufficient but could elaborate on what 'overall_faster' and 'compounds_compared' imply.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with each parameter having a description. The description adds structure by listing parameters and their types in the Args block, and clarifies the return shape with a brief outline of the data fields. This goes beyond the schema by providing a high-level view of what the output contains.
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 ('Compare') and clearly identifies the resource ('race-pace and tyre degradation between two F1 drivers in a session'). It distinguishes from siblings like f1_tyre_degradation and f1_head_to_head_pace by focusing on pairwise comparison with compound breakdown.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

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 explains two input modes: using match_id alone or providing team_a, team_b, and venue together. It states when each parameter is required ("Required if match_id is absent"). However, it does not directly advise when to use this tool over alternatives like cricket_captain_recommendation, though the purpose differs.
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?
Annotations (readOnlyHint, openWorldHint, idempotentHint, destructiveHint) are consistent and description adds critical context: empty results, neutral baseline, events_analysed count, and reasoning. No contradiction.
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 a clear purpose, note, args, and returns. It is front-loaded and concise for the complexity, though slightly verbose with the NOTE section.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the output schema exists, the description explains the empty list, events_analysed, model, and note. It covers all relevant behaviors and meta information, making it fully complete.
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 coverage is 100%, so the description's parameter info is largely redundant. However, it adds context for min_edge ('Currently informational only'), which adds some value beyond schema descriptions.
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 'Compare model probabilities against market-implied IPL odds' with a specific verb and resource. It distinguishes from siblings like cricket_get_live_odds and mentions a required key.
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?
Explicitly notes the current limitation (empty list until model is wired) and provides an alternative: 'For raw de-vigged prices use cricket_get_live_odds'. Also explains behavior for filtering with team and min_edge.
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?
Annotations (readOnlyHint, openWorldHint, idempotentHint) are consistent. The description adds key behavioral details: internal call to football_find_value_bets, selection of strongest legs, return of risk_flag and independence_warning. 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?
Description includes docstring with Args and Returns blocks. Some redundancy with param descriptions, but overall well-structured and informative. Could be slightly more concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (joint probability model, internal call), the description covers purpose, workflow, parameters, and return fields. Output schema exists, and the description complements it.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with descriptions and defaults. The description repeats param info but adds context on how they are used (selects strongest legs based on edge), providing marginal added 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 models joint probability of match outcomes using top model-vs-market gaps, calls an internal function, selects strongest legs, and combines them. It distinguishes from siblings like cross_sport_build_accumulator and cricket tools.
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 internal workflow and parameters (legs, min_edge). It implies usage for building accumulators from value bets but does not explicitly state when to use vs. alternatives or 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?
The description discloses that it requires an API key and returns a clean error envelope if missing. Annotations already provide readOnlyHint=true, and the description adds context about external source and caching behavior (meta.source). 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?
The description is well-structured with clear sections for Args and Returns. It is concise but includes necessary details. A minor deduction for slight verbosity in the parameter explanation, but overall efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given that an output schema exists (context confirms), the description still provides the return structure explicitly. It covers input, output, error handling, and source. Complete for an AI agent to use correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The only parameter 'team' is thoroughly explained in the description: case-insensitive substring matching against both sides, and the limitation that CricAPI match_id cannot be used due to opaque event ids. This adds meaning beyond the schema, which already included the same description.
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 returns live market head-to-head odds for IPL matches. It uses specific verb 'Return' and resource 'live market head-to-head odds', distinguishing it from siblings like cricket_get_live_matches or football_get_odds.
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 when to use it (for IPL odds) and mentions the requirement of THEODDS_KEY. It doesn't explicitly state when not to use or list alternatives, but the context from sibling tools and the specific IPL focus make usage clear.
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?
Annotations indicate readOnlyHint, openWorldHint, idempotentHint, and non-destructive. The description adds extensive behavioral context: it simulates 12 groups, advances top 2 + 8 best third-placed teams to knockout, and plays to a champion. It also details clamping, seed use, and output structure, exceeding annotation coverage.
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 a clear summary, followed by structured details (Args, Returns, Example). Every sentence adds value without redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity and the existence of an output schema, the description fully explains the simulation scope, input parameters, output structure, and provides an example. It also notes that completed matches are locked, covering edge cases.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%. The description adds value by explaining the iteration clamping range and that ~10000 gives stable ±2% probabilities. For seed, it repeats the schema description. This additional context justifies a score above baseline 3.
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 performs Monte Carlo simulation of the full World Cup 2026 bracket, computing per-team round and title probabilities. It distinguishes from sibling tools like football_simulate_group by focusing on the entire tournament.
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 when to use the tool (to simulate the full bracket) and provides usage details like iteration clamping and recommended values for stability. It does not explicitly state when not to use it or list alternatives, but the context of sibling tools implies its specific role.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
