Tool Scores

• clear_breakpointC
  2.9/5.0
  Behavior2/5

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

  No annotations provided, so description must disclose behavior. It only states the action and parameter meanings, omitting side effects, error handling, or whether it requires a halted target. Lack of behavioral context is a significant gap.

  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 short and front-loaded with the main purpose. The Args section is structured for clarity. However, it could include more useful information without becoming 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?

  Given the tool's simplicity, the description is incomplete. It does not explain the return value (though output schema exists), error conditions, or behavior when multiple parameters provided. An agent would lack key details for reliable 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?

  Schema coverage is 0%, so the description adds meaning by explaining each parameter's format (e.g., hex string for address, integer for handle). However, details are minimal and do not cover edge cases or constraints (e.g., symbol requires ELF loaded).

  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 'clear breakpoint' as the action and specifies the resource type. It distinguishes from clear_all_breakpoints by indicating clearing a single breakpoint via address, symbol, or handle, but does not explicitly contrast with siblings.

  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 lists three ways to specify the breakpoint but provides no guidance on when to use this tool versus clear_all_breakpoints, no prerequisites (e.g., breakpoint must exist), and no context on exclusive parameter usage.

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

• write_rttB
  3.2/5.0
  Behavior2/5

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

  No annotations provided. The description does not disclose behavioral traits such as required state (e.g., target halted), blocking behavior, side effects, or error handling for invalid channels.

  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 Chinese sentence followed by a well-structured English docstring (Args/Returns). Some redundancy exists but overall efficient.

  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 the purpose and return value, but lacks context about when to use the tool (e.g., after connection), interaction with sibling tools, or prerequisites for success.

  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?

  With 0% schema description coverage, the description partially compensates by explaining text and channel. However, the explanations are minimal and mostly restate parameter names and defaults.

  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 sends data to the RTT input channel (target microcontroller). It distinguishes from sibling tools like read_rtt by specifying 'write' direction.

  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 (e.g., write_memory, write_variable). It does not state prerequisites or context such as requiring a connection or target state.

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

• get_symbol_addressB
  3.3/5.0
  Behavior2/5

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

  With no annotations, the description bears full responsibility for behavioral disclosure. It mentions the dependency on 'load_elf()' but does not address error cases (e.g., symbol not found, ELF not loaded) or side effects. The return is described but without error handling or success/failure 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 concise and well-structured with clear sections (Args, Returns). It efficiently communicates the tool's purpose and usage without extraneous information. The front-loading of the main sentence is good.

  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 the tool's simplicity (single parameter) and the presence of an output schema (though not shown), the description is adequate. It covers prerequisite, parameter, and return value. However, it lacks information on error handling or behavior when the symbol doesn't exist, which would be expected for a query tool.

  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?

  The input schema provides only a 'symbol' string parameter with no description (0% coverage). The description compensates by explaining that the symbol can be a function or global variable name, and provides examples like 'main' and 'SystemCoreClock', adding meaningful context beyond the schema.

  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 that the tool queries the memory address of a symbol (function or global variable). This distinguishes it from siblings like 'list_functions' (which only returns names) and 'read_variable' (which reads the value). The prerequisite mention of 'load_elf()' adds context, though it does not explicitly differentiate from all siblings.

  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 provides an explicit prerequisite ('need to call load_elf() first'), which serves as a usage guideline. However, it lacks details on when not to use this tool or how it compares to alternatives like 'read_variable' or 'list_functions' for address retrieval.

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

• write_memoryA
  3.8/5.0
  Behavior2/5

  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 states the write action but provides no details on behavioral traits such as potential side effects (e.g., memory corruption), required target state (e.g., halted), or permission needs. Minimal disclosure beyond the basic 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?

  The description is concise with clear sections (Args, Returns) and no extraneous content. Every sentence adds value, making it efficient for an AI agent to parse.

  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 the presence of an output schema, the vague return description ('写入结果') is acceptable, but the description lacks important context such as prerequisites (e.g., target must be halted) or error conditions. It is adequate but not comprehensive for a write operation.

  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?

  With schema description coverage at 0%, the description fully compensates by detailing parameter formats: address as hex string, data lists varying by width, and width enumeration (8/16/32). This adds significant meaning beyond the raw schema types.

  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 ('向目标内存写入数据', write data to target memory) and resource (memory). It distinguishes from siblings like read_memory, write_register, and write_variable, making the tool's specific 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 Guidelines3/5

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

  The description implies usage for writing to raw memory but does not explicitly state when to use this tool versus alternatives like write_register or write_variable. No exclusion criteria or prerequisites (e.g., need to halt target) are mentioned.

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

• read_rttA
  3.9/5.0
  Behavior3/5

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

  With no annotations, the description carries the full burden. It states the tool is non-intrusive and does not need to halt the target, which is good. However, it does not disclose potential side effects (e.g., does reading clear the buffer?), error conditions, or authentication requirements.

  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 concise overview and structured Args/Returns sections. Some redundancy exists (e.g., first sentence and last sentence both mention reading RTT content), but overall it is 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 no annotations and 0% schema coverage, the description fairly covers prerequisites, parameters, and output. It lacks details on error handling or blocking behavior, but for a simple read tool, it is adequately complete.

  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?

  The schema has 0% coverage, so the description must explain parameters. It provides default values and context: channel 0 is typical for log output, max_bytes limits read size. This adds significant meaning beyond the schema's bare titles.

  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 reads SEGGER RTT buffer content, explains what RTT is, and distinguishes it from the sibling write_rtt tool. The verb '读取' (read) and resource 'RTT 缓冲区内容' are specific.

  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?

  Describes a prerequisite (target firmware must include SEGGER RTT library), but does not explicitly state when to use this tool versus alternatives like read_memory or when not to use it. No exclusions or sibling comparisons are given.

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

• set_breakpointA
  3.9/5.0
  Behavior2/5

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

  No annotations are provided, so the description must fully disclose behavioral traits. It mentions the prerequisite of load_elf for symbols, but does not cover other important aspects such as whether a connection is required, whether the target must be halted, or what happens if an invalid address is provided. The description is insufficient for complete transparency.

  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?

  Schema description coverage is 0%, so the description must add meaning. It provides format examples for address (hex string) and symbol (function name), and explains the dependency on load_elf for symbols. This goes beyond the schema's minimal structure.

  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: setting a breakpoint at a specified address or function name. It specifies that one of address or symbol must be provided, and distinguishes from sibling tools like list_breakpoints and clear_breakpoint.

  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 clear usage guidance: it states that either address or symbol must be provided, and notes that using a symbol requires prior loading of an ELF file via load_elf(). This helps the agent understand prerequisites, though it could explicitly state when not to use this tool relative to others.

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

• get_statusA
  4/5.0
  Behavior3/5

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