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

Annotations already indicate read-only, non-destructive, and idempotent behavior, but the description adds valuable context beyond this: it specifies the types of recommendations provided (achievements, voice packs, gamification patterns) and hints at the tool's scope ('context-specific usage tips'). This enhances understanding without contradicting annotations.

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

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

The description is front-loaded with the core purpose in the first sentence, followed by specific examples of what it provides. Every sentence adds value without redundancy, making it efficient and well-structured for quick comprehension.

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

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

Given the tool's low complexity (1 optional parameter, no output schema) and rich annotations, the description is mostly complete. It covers purpose and usage context well, but could slightly improve by hinting at the output format or linking to sibling tools for more details on specific topics like achievements or voice packs.

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

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, with the 'context' parameter fully documented in the schema (including enum values and examples). The description mentions 'context-specific usage tips' but does not add meaning beyond what the schema provides, such as explaining how different contexts affect the output. Baseline 3 is appropriate given high schema coverage.

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

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

The description clearly states the tool's purpose with specific verbs ('get context-specific usage tips and best practices') and resources ('for AI assistants using this MCP server'). It distinguishes from siblings by focusing on usage guidance rather than achievements, stats, voice packs, or sound effects, which are covered by other tools.

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

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

The description provides clear context for usage ('when to trigger achievements, how to use voice packs effectively, and integration patterns for gamifying development workflows'), but it does not explicitly state when not to use this tool or name specific alternatives among the siblings. The context is implied through the examples given.

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

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

Annotations provide readOnlyHint=true, destructiveHint=false, idempotentHint=true, and openWorldHint=false, covering safety and idempotency. The description adds value by specifying the return content (detailed information about each achievement, including when to use them, what they represent, and voice pack support), which goes beyond annotations to clarify output behavior and context. No contradiction with annotations.

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

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

The description is front-loaded with the main purpose in the first sentence, followed by specifics about return content. It uses two concise sentences with no wasted words, effectively communicating key information without redundancy or unnecessary elaboration.

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

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

Given the tool's complexity (read-only guide retrieval with one optional parameter), rich annotations cover safety and idempotency, and the description adds output details. However, there is no output schema, so the description partially compensates by describing return values, but could be more complete by specifying format or structure. It is adequate but has a minor gap in output specification.

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

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, with the parameter 'category' fully documented in the schema including enum values and filtering behavior. The description does not add parameter-specific details beyond the schema, so it meets the baseline of 3 for high schema coverage without compensating with extra semantic information.

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

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

The description clearly states the verb 'Get' and resource 'comprehensive guide explaining all available achievements', specifying content like categories, thresholds, and usage recommendations. It distinguishes from siblings by focusing on detailed explanations rather than stats (get_enhanced_achievement_stats), lists (list_enhanced_achievements), or other functions like playing sounds or setting configurations.

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

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

The description implies usage for understanding achievements comprehensively, but does not explicitly state when to use this tool versus alternatives like get_enhanced_achievement_stats for statistics or list_enhanced_achievements for basic listings. It provides context about the guide's content but lacks direct guidance on tool selection among siblings.

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

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering safety and idempotency. The description adds valuable context by listing specific return fields (e.g., session duration, current streak, achievements per minute rate), which helps the agent understand what data to expect beyond just 'statistics'. It does not contradict annotations, as 'retrieve' aligns with read-only behavior.

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

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

The description is a single, efficient sentence that front-loads the purpose ('Retrieve comprehensive session statistics and achievement progress') and follows with a detailed list of return values. Every element adds value by specifying what data is included, with no wasted words or redundancy.

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

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

Given the tool's complexity (retrieving multiple stats), annotations provide good safety coverage, and the description details the return fields comprehensively. However, there is no output schema, so the description must fully explain return values, which it does by listing them explicitly. It could improve by mentioning data formats or units (e.g., duration in minutes), but it is largely complete for a read-only stats tool.

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

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 100% description coverage, with the parameter '_dummy' documented as 'No parameters required'. The description reinforces this by stating 'Returns session statistics without requiring any input', adding clarity that no user input is needed. This compensates for the dummy parameter's potential confusion, earning a score above the baseline of 3.

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

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

The description clearly states the verb 'retrieve' and the resource 'comprehensive session statistics and achievement progress', making the purpose specific. It distinguishes from siblings like 'list_enhanced_achievements' by focusing on aggregated stats rather than listing individual achievements, and from 'get_ai_usage_guide' or 'get_enhanced_achievement_guide' by providing data rather than instructions.

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

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

The description provides no explicit guidance on when to use this tool versus alternatives. It does not mention when this tool is appropriate (e.g., for summary reports) or when to prefer other tools like 'list_enhanced_achievements' for detailed lists, leaving usage context implied at best.

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

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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, and openWorldHint=false, covering safety and idempotency. The description adds value by specifying the return content (current voice pack details and list of all available packs), which isn't covered by annotations, providing useful behavioral context beyond the structured hints.

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

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

The description is a single, well-structured sentence that efficiently conveys the tool's purpose and return value. It uses an emoji for visual emphasis and avoids redundancy, making it front-loaded and appropriately sized with no wasted words.

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

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

Given the tool's low complexity (no real parameters, read-only operation) and rich annotations, the description is mostly complete. It specifies what information is returned, compensating for the lack of an output schema. However, it could briefly mention the tool's idempotent or safe nature, though annotations cover this, leaving a minor gap.

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

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 100% schema description coverage, the schema fully documents the single dummy parameter. The description adds no parameter-specific information, but since there are effectively 0 functional parameters (the dummy parameter is a placeholder), this is acceptable. The baseline for high schema coverage is 3, but the lack of real parameters elevates the score to 4.

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

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

The description clearly states the verb ('Get information') and resource ('about the currently active voice pack and all available voice packs'), distinguishing it from sibling tools like 'set_voice_pack' or 'test_voice_packs'. It specifies the scope of information returned, making the purpose explicit and differentiated.

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

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

The description implies usage context by stating it returns information about 'currently active' and 'all available' voice packs, suggesting it's for querying voice pack details. However, it doesn't explicitly state when to use this tool versus alternatives like 'set_voice_pack' or 'test_voice_packs', nor does it provide exclusions or prerequisites.

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

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

Annotations already indicate read-only, non-destructive, idempotent, and closed-world behavior. The description adds value by specifying the return format ('Returns achievement names, categories, and thresholds') and the optional filtering capability, which are not covered by annotations. No contradiction with annotations.

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

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