• get_chapter_sectionB
  3.2/5.0
  Behavior3/5

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

  The description reveals that the tool returns text and associated images, which is a meaningful behavioral disclosure. However, with no annotations provided, the description carries the full burden and does not mention failure behavior, how context_level affects the output, or how images are delivered. Since this is a read operation, destructive behavior is not a concern, but the rest of the behavioral profile is thin.

  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 a single front-loaded sentence with no filler; every clause adds useful information about the target scope and returned contents. It is appropriately concise, though the brevity comes at the cost of contextual completeness.

  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?

  There is no output schema, and the description only says 'text and associated images,' leaving ambiguous the output format and what granularity 'specific section' means. It does not explain how the context_level parameter (brief/detailed/comprehensive) alters results, nor does it distinguish this tool from get_chapter_text or extract_chapter_content. A more complete description would need a usage example and a note on when to choose this over siblings.

  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 all four parameters are already described in the input schema. The tool description adds no parameter-specific detail beyond implying the output content. The baseline of 3 applies because the schema does the heavy lifting for parameter documentation.

  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 states a specific verb and resource: 'Get a specific section of a chapter' and clarifies the output includes 'text and associated images.' It implicitly distinguishes itself from the sibling get_chapter_text by emphasizing a targeted section rather than whole-chapter content, though it does not explicitly name alternatives.

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

  Usage Guidelines2/5

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

  No guidance is given on when to use this tool versus siblings like get_chapter_text, search_content, or extract_chapter_content. The description contains no exclusions, prerequisites, or context triggers. The only subtle usage hint is the word 'specific,' which weakly implies a targeted lookup, but this is not enough to route an agent correctly.

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

• extract_chapter_contentA
  3.6/5.0
  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 does disclose a key behavioral trait: the tool caches extracted content, which signals a persistent side effect. However, it does not describe what happens on cache hits, whether force_reextract overwrites, what it returns, or permissions needed.

  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?

  One sentence with no wasteful words. The action, resource, side effect, and purpose are all packed in efficiently and front-loaded.

  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?

  For a tool with no annotations, no output schema, and a caching side effect, this description is too thin. It leaves important questions unanswered: does it return the extracted content or just cache it, how does force_reextract interact with existing cache entries, and when should the agent use this versus the sibling get/search tools?

  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 the schema already documents all three parameters. The description adds no extra semantic meaning beyond 'text and images', so the baseline of 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?

  States a specific verb ('Extract'), resource ('text and images from a chapter'), and a clear side effect ('cache') for a defined purpose ('future searches'). This clearly differentiates it from sibling retrieval tools like get_chapter_text and get_chapter_section.

  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 phrase 'for future searches' implies this is a preparation step before search_content, but it does not explicitly state when to choose this over get_chapter_text or get_chapter_section, nor does it mention any exclusions or prerequisites.

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

• get_chapter_textA
  3.7/5.0
  Behavior3/5

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

  With no annotations, the description carries the burden. It adds that the tool performs extraction and cleaning and returns readable text, but it does not mention caching behavior, force re-extraction, or truncated output by default. These are visible only in parameter descriptions, not in the tool description.

  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?

  One sentence that leads with the core purpose and follows with the key differentiator. No wasted words or redundancy.

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

  Completeness3/5

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

  The description is enough to identify what the tool returns, and the schema handles parameter semantics. However, it leaves gaps around how this relates to get_chapter_section and extract_chapter_content, and it does not surface that results are limited by length/start_chars. Some of this is recoverable from schema defaults, but not fully.

  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 every parameter has a useful description, such as start_chars as the starting character position and force_reextract as a cache override. The tool description adds no additional parameter meaning, so it sits at the high-coverage baseline of 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?

  States a specific action and resource: getting readable text from a chapter. The phrase 'combines extraction and cleaning into one tool' differentiates it from the sibling extract_chapter_content, and 'from a chapter' distinguishes it from get_chapter_section.

  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?

  Implies it should be used when cleaned readable text is wanted instead of raw extraction, but it does not explicitly say when to use alternatives like get_chapter_section or extract_chapter_content. No when-not conditions or alternative tool names are provided.

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

• search_contentA
  3.7/5.0
  Behavior3/5

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

  With no annotations provided, the description carries the full burden of behavioral disclosure. It does add useful behavioral context by mentioning that results are relevant sections with page references. However, it does not explain query matching behavior, what counts as 'relevant,' or what happens when there are no matches.

  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 a single, front-loaded sentence with no filler. It communicates the core action, resource, and output type efficiently.

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

  Completeness3/5

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

  For a simple two-parameter tool, the description covers the main purpose and return value. However, it leaves ambiguity about the search scope (single PDF vs. all extracted text), search semantics, and how max_results affects ranking or relevance. These gaps matter given there is no output schema and no 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?

  The schema already provides full descriptions for both parameters, so the baseline is 3. The description adds general context about returning relevant sections with page references but does not add parameter-specific meaning beyond what the schema states.

  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 states a specific verb ('search') and resource ('extracted PDF text') and specifies the return value ('relevant sections with page references'). This clearly differentiates it from sibling tools that list, extract, or get chapter content.

  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 when to use the tool: when the user needs to search within extracted PDF text. However, it does not explicitly distinguish it from alternatives like get_chapter_section or extract_chapter_content, nor does it clarify whether the search covers a single document or all extracted PDFs.

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

• list_books_and_chaptersA
  4/5.0
  Behavior3/5

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

  With no annotations, the description carries the full burden of behavioral disclosure. It clearly signals a read-only listing operation and specifies what metadata is included, but it does not mention pagination, result size, failure behavior, or any access limitations. For a simple listing tool, this is adequate but not deeply transparent.

  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 a single, front-loaded sentence that immediately identifies the action and scope, then adds useful specifics about status and metadata. Every part earns its place, with no filler or repetition.

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

  Completeness4/5

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

  For a zero-parameter listing tool with no output schema and no annotations, the description provides enough information for an agent to understand what will be returned: books, chapters, extraction status, and content metadata. It could add details about output format or scale, but those are reasonable gaps for a simple list endpoint.

  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 tool has zero parameters, so there is nothing for the description to explain beyond what the empty schema already shows. The description compensates by clarifying what the returned data contains, which is the relevant semantic information for this tool.

  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 'List' with a clear resource scope: books and their PDF chapters, plus the particular data included (extraction status, content metadata). It is immediately distinct from siblings that search or extract content, and there is no ambiguity about what the tool returns.

  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 it should be used when an agent needs an overview of available books and chapters, but it does not explicitly state when to choose it over siblings such as search_content or get_chapter_text. There is no when-not guidance or mention of alternatives, leaving the routing decision mostly to inference.

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