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

With no annotations available, the description carries the full burden. It clearly indicates the tool extracts specific information and likely provides a structured summary, which is a transparent account of its observable behavior. However, it does not explicitly mention that it is read-only or whether it requires special permissions, but the analyze verb implies non-mutating 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, concise sentence that front-loads the action and lists the output components without unnecessary filler. Every word contributes to understanding the tool's core function.

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?

The tool is relatively simple, but the description lacks parameter guidance, usage alternatives, and any note about return format or limitations. The extraction list provides a clear idea of the output, but given no output schema and no annotations, the description is only partially complete for a robust agent understanding.

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 0%, and the description does not elaborate on the parameters (mc_dir, crash_file). The names imply their roles (Minecraft directory and crash file path), but the description fails to compensate for the complete lack of schema documentation, leaving the AI to infer parameter format and how they should be provided.

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 uses a specific verb '解析' (analyze) with a clear resource '崩溃报告' (crash report), and lists the extracted components (Minecraft version, exception type, error message, top stack info, summary). This distinguishes it from siblings like find_crash_reports or read_log, which find or read files without performing structured analysis.

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 when a single crash report needs analysis, but it does not explicitly state when to use this tool versus alternatives like read_log or find_crash_reports, nor does it provide exclusions. The scope is clear but without explicit guidance.

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?

With no annotations, the description must disclose behavior itself. It mentions the API source and the type of data returned, but it does not state whether the operation is read-only, any network assumptions, rate limits, or what happens if dependencies are not found.

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, front-loaded sentence that uses a colon to list key outputs. Every phrase contributes meaningful information without 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?

The tool is relatively simple and the description covers its main purpose and outputs. However, with no annotations, no output schema, and no parameter-level explanations, it leaves gaps about loader semantics and expected result format that could affect correct invocation.

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 0%, yet the description only implicitly references mc_version through the 'MC version compatibility list' phrase. It does not explain project_id's role or the optional loader parameter's format/effect, leaving the agent to infer from field names alone.

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 function: querying mod dependency information via the Modrinth API. It names specific outputs (latest compatible version, required/optional dependencies, MC version compatibility list) and distinguishes it from siblings like get_version_info and detect_conflicts.

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?

Usage context is implied by the purpose (when you need dependency info), but there is no explicit guidance about when to use this tool versus siblings or any exclusions. No alternative tools are named.

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?

With no annotations provided, the description carries full burden. It discloses that the scan targets known conflict combinations, but doesn't specify whether it modifies anything, read-only nature, or what actions it takes. It's fairly clear it's a read operation, but lacks details on output 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.

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

The description is a single sentence, front-loaded with the core purpose, and provides concrete examples of conflict types. It's concise and structured well, though it could benefit from a brief mention of parameters.

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

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

Given the tool's moderate complexity (checking known conflicts) and absence of output schema or annotations, the description gives a reasonable overview but omits parameter semantics and output details. It is adequate but not fully complete for an agent to invoke without further inference.

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

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

Schema coverage is 0%, and the description does not explain the parameters (mc_dir and instance_id). With no parameter descriptions in the schema and none in the text, the agent must infer their meaning, which is a significant gap.

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 scans the mods/ directory for known conflict combinations, listing specific examples (renderer conflicts, UI lib duplicates, JEI duplicates, Fabric API duplicates). This distinguishes it from siblings like check_mod_dependencies (which likely checks individual dependencies) and scan_cleanliness (which may check something else).

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 when checking for known mod conflicts, but provides no explicit guidance on when to use this over alternatives like check_mod_dependencies. There are no explicit exclusions or alternative suggestions, falling short of full usage guidelines.

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?

With no annotations, the description carries the full burden. It discloses the read-only nature (listing) and the return values, but lacks details on error handling, directory existence, or permission requirements. This is adequate for a simple list operation but not rich.

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. It front-loads the core action and return values without any filler 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?

For a simple listing tool, the description covers the main action and return values. However, the unexplained required parameter mc_dir leaves a significant gap, and the absence of an output schema means the return format is only partially specified. This is minimally viable but not complete.

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 only parameter mc_dir has no schema description (0% coverage) and the description never mentions it. The agent is left guessing what mc_dir means (likely Minecraft directory, but not stated). The description fails to compensate for the lack of schema documentation.

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 lists all crash reports in the crash-reports/ directory and returns file names and modification times. This specific verb-resource pairing distinguishes it from siblings like analyze_crash and read_log.

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 clearly implies when to use this tool (when you need to enumerate crash reports) but does not explicitly mention exclusions or alternatives. The context is clear but doesn't state 'don't use for analyzing specific crashes' or similar.

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?

The description discloses that it reads a configuration file and auto-probes common locations when no directory is given. This indicates a read-only, non-destructive operation, but does not explicitly state side effects or permissions. Since no annotations are present, the description carries full transparency burden; it is mostly transparent.

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

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

The description is concise, consisting of two clear sentences. It efficiently conveys the tool's purpose and the parameter's optional behavior without unnecessary detail.

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?

The description provides sufficient context for the tool's core functionality and the parameter's role. It does not detail output format or error handling, but given the simple nature of the tool and lack of output schema, it is reasonably complete.

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 description explains the behavior when 'mc_dir' is omitted (auto-probing), which adds meaning beyond the bare schema. However, it does not clarify what 'mc_dir' represents (e.g., Minecraft directory vs. PCL config directory) or its expected format, leaving some ambiguity.

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 function: reads the PCL configuration file and lists all available Java runtime versions and their paths. It also mentions automatic probing when 'mc_dir' is not provided, which further clarifies its purpose.

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 when to use the tool (when Java version info is needed), but does not explicitly contrast it with sibling tools or provide specific scenarios. No alternative tools are mentioned.

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?

Since no annotations are provided, the description carries the full burden. It clearly indicates a read operation (reading a file and returning metadata), but it does not explicitly mention side effects, permissions, or potential pitfalls (e.g., what happens if the file is missing). It is transparent about its primary behavior but lacks depth on edge cases.

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, concise sentence that conveys the essential purpose and output without unnecessary elaboration 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?

The description provides a good overview of the output (metadata list) and the input file (version.json), but it lacks details on error handling, return structure, or any prerequisites. For a read-only tool, this might be adequate, but the absence of output schema or example usage leaves the context incomplete.

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 schema defines two parameters (mc_dir and instance_id) with only type information. The description does not explain what these parameters represent or how they should be used. There is no mention of their purpose, format, or expected values, leaving the user to infer their meaning from the names alone.

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 function: reading version.json of a specified Minecraft version and returning specific metadata such as game version, Loader version, Java requirements, JVM parameters, and mod count. This is distinct from the sibling tools, which focus on other aspects like mod listing, conflict detection, and log reading.

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 does not provide explicit guidance on when to use this tool versus the alternatives. It is implied that it is for retrieving version information, but no direct comparison or contextual cues are given, such as 'use this when you need version metadata' or 'for mod-related issues, use list_mods instead.'

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?

With no annotations provided, the description must disclose behavioral traits. It only mentions scanning and listing, but does not state whether the operation is read-only, what happens if the directory is missing, or any side effects. There is no mention of permissions, errors, or return format.

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 extremely concise, using two short sentences to convey the primary purpose and a key parameter detail. There is no wasted text, and it is front-loaded with the main action.

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 lack of annotations and output schema, the description is the only source of context. It does not mention the output format, what 'basic information' includes, or behavior in edge cases (e.g., empty directory). This leaves significant gaps for an agent trying to use the tool correctly.

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

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

Schema coverage is 0%, so the description must compensate. It does explain that 'filter' supports regex and is for name filtering, but it does not explicitly define 'mc_dir' and 'instance_id' beyond the schema's type declarations. The description implies they specify the instance and directory, but not fully.

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: scanning the mods/ directory of a given instance and listing JAR files with basic information. It also mentions the regex-based filtering capability, distinguishing it from sibling tools like get_java_versions or detect_conflicts.

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 does not provide any guidance on when to use this tool versus alternatives, nor any conditions or exclusions. It simply describes the function without contextualizing its use case relative to sibling tools.

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