• list_favoritesB
  3.3/5.0
  Behavior2/5

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

  No annotations are provided, so the description carries full burden. It implies a read operation ('List') but does not explicitly confirm no side effects, nor does it disclose pagination behavior (despite a 'limit' parameter in schema). Return format or sorting order is omitted.

  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?

  Single sentence, no redundant words. Every word contributes to understanding the tool's core function. Highly concise.

  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 tool is simple with 2 optional params, but no output schema exists. The description does not hint at return fields (e.g., URL, name, folder). For a basic list tool, this is minimally adequate but lacks completeness.

  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 coverage is 100% with both parameters described. The description adds no new semantic value beyond restating the folder filter (already in schema). Baseline 3 is appropriate given high 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 uses the specific verb 'List' and identifies the resource 'all Edge browser favorites', along with an optional filter by folder path. This clearly distinguishes it from sibling tools like 'search_favorites' (which searches) and 'list_folders' (which lists folders).

  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 only mentions optional filtering, but provides no explicit guidance on when to use this tool versus alternatives (e.g., when to use 'search_favorites' for keyword searches or 'list_folders' for folder enumeration). No 'when not to use' or prerequisite conditions are stated.

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

• list_foldersA
  3.5/5.0
  Behavior2/5

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

  No annotations provided, and description only states the action. Does not disclose whether it is read-only, requires authentication, or any side effects. Minimal behavioral disclosure.

  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?

  Single sentence delivering complete functionality without waste. Front-loaded with verb and resource.

  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?

  Adequate for a simple zero-param tool, but lacks output format details (e.g., array of strings vs objects). With no output schema, slightly more context would help.

  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?

  No parameters exist; description adds no parameter info, but baseline for 0 parameters is 4 per guidelines.

  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?

  Description clearly states it lists all unique folder paths in Edge favorites, distinguishing it from siblings like list_favorites (likely lists all favorites) and read_favorite_content (reads a specific favorite).

  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 on when to use this tool versus alternatives like list_favorites or search_favorites. Agent must infer context from name alone.

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

• read_favorite_contentA
  3.8/5.0
  Behavior3/5

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

  No annotations are provided, so the description bears full responsibility for behavioral disclosure. It discloses that the fetch is best-effort and may fail for authenticated pages, and that output is extracted text. However, it does not cover error handling, rate limits, or specific failure behaviors.

  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 two sentences long, front-loads the action, and contains no extraneous information. Every sentence provides necessary context efficiently.

  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 two parameters and no output schema, the description covers the main purpose, behavioral caveats, and return type. It could be slightly more complete by mentioning error cases or format expectations, but overall it is sufficient.

  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% with clear parameter descriptions. The tool description adds no additional parameter-level information beyond what the schema provides, so baseline score 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?

  The description clearly states the action ('Fetch the content of a favorite's URL') and the purpose ('to get more context about the page'). It distinguishes from sibling tools (list_favorites, list_folders, search_favorites) that deal with listing or searching metadata rather than fetching 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 includes a caveat about best-effort and potential failure for authenticated pages, which provides some usage guidance. However, it does not explicitly compare this tool to its siblings or state when to prefer it over alternatives.

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

• search_favoritesA
  4/5.0
  Behavior3/5

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

  No annotations are provided, so the description must disclose behavioral traits. It describes the search operation and match fields but does not explicitly state that it is read-only or has no side effects. This leaves uncertainty for the agent.

  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 consists of two concise sentences. The first provides the core purpose, and the second adds a helpful tip. No unnecessary words or redundancy.

  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 simplicity with one parameter and no output schema, the description adequately covers the search behavior and match fields. The tip about using read_favorite_content adds workflow context. However, it does not describe the return format.

  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 for the single parameter is 100%, so the baseline is 3. The description adds value by explaining that the query matches against name, URL, and folder path, which is not in the schema 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 the tool searches favorites/bookmarks by keyword, specifying it matches against name, URL, and folder path. This effectively distinguishes it from sibling tools like list_favorites and list_folders.

  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 (search by keyword) and includes a tip about next actions, but does not explicitly state when not to use it or how it differs from alternative tools like list_favorites for browsing all items.

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