  2.7/5.0
  Behavior2/5

  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 mentions that the plan is 'risk-based' and 'grounded in test and defect evidence,' but it does not disclose what the tool returns, how it uses release_id and max_tests, or whether it only reads data.

  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?

  A single front-loaded sentence with no filler or redundancy. It begins with the action and object and adds value by specifying risk-based and evidence-grounded characteristics.

  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 two parameters, no annotations, and no output schema, this one-line description is incomplete. It does not explain expected outputs, the role of max_tests, or selection criteria, leaving important context for correct invocation unspecified.

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

  Parameters1/5

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

  Schema description coverage is 0% and the description never mentions release_id or max_tests. The phrase 'test and defect evidence' does not explain the required release parameter or the meaning of the max_tests default, so the agent gets no parameter help beyond field names.

  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 action, 'Build a risk-based regression plan,' and a clear resource. It distinguishes itself from sibling tools by focusing on test recommendation and evidence grounding, though it does not explicitly name or contrast any sibling.

  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 for when to use this tool versus assess_release_readiness, get_failed_tests, or find_defect_hotspots. There are no prerequisites or exclusions, so an agent must infer usage solely from the name and purpose.

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

• get_failed_testsB
  3.1/5.0
  Behavior2/5

  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 states the output (failed/blocked tests) but does not mention pagination, ordering, empty-result behavior, required release context, or consequences. Nothing contradicts annotations because none exist.

  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 word adds meaning, and the main result is stated before the optional filter.

  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?

  Despite a simple two-parameter shape and an output schema, the definition lacks enough context for confident invocation: no sibling differentiation, no release_id semantics, and no criticality value guidance. This is insufficient for a low-coverage schema.

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

  Parameters2/5

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

  Schema description coverage is 0%, so the description must compensate. It only clarifies the optional criticality filter; it does not explain release_id or enumerate accepted criticality values, leaving a required parameter largely undocumented.

  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 names a specific verb and resource: 'Return failed and blocked tests'. This clearly distinguishes it from siblings like assess_release_readiness and recommend_regression_tests, which are analysis/recommendation tools rather than retrieval tools.

  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 about when to prefer this tool over its siblings. The only usage hint is the optional criticality filter, which is more of a parameter option than a when-to-use instruction.

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

• assess_release_readinessB
  3.3/5.0
  Behavior3/5

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

  With no annotations, the description carries the behavioral burden. It discloses that the output is an explainable recommendation with three possible values, but it does not reveal how the recommendation is derived, whether it depends on external sources, or what 'explainable' means in practice. This is acceptable 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.

  Conciseness5/5

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

  A single sentence that front-loads the action and outcome with no filler. It is appropriately sized for a one-parameter tool.

  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 has only one parameter and no output schema, and the description names the three output categories, which covers the basic return shape. But it omits the criteria behind the recommendation, the source of the release ID, and any caveats, leaving the agent with an incomplete picture of how to invoke and interpret it.

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

  Parameters2/5

  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 release_id beyond the schema's string type and title. Since the only parameter is central to the tool, the description should at least clarify what qualifies as a release_id and how it is used; it does not.

  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?

  States a clear action ('Calculate') and a specific deliverable ('GO, CONDITIONAL_GO, or NO_GO recommendation'), which goes beyond the tool name. It is distinguishable from the sibling tools by its outcome-oriented purpose, though it does not explicitly contrast itself with them.

  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 usage context is implied: this is the high-level readiness assessment tool, while siblings like get_failed_tests and find_defect_hotspots are lower-level diagnostic tools. However, the description never states when to use this tool versus its alternatives, so an agent must infer the boundary.

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

• find_defect_hotspotsB
  3.4/5.0
  Behavior3/5

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

  With no annotations, the description carries the behavioral disclosure burden. It implies a read-only ranking operation and specifically scopes to unresolved defects, but it does not explain how 'weighted risk' is computed, whether historical data is considered, or what happens when no defects are found. Basic but not rich behavioral context.

  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?

  A single sentence that front-loads the action and object, then adds the precise qualifier. Every word earns its place with no filler 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 output schema covers return values, and the single parameter is simple. However, the description omits when to prefer this over sibling tools and does not clarify the meaning of 'components' or 'weighted risk.' It is minimally viable but leaves notable gaps.

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

  Parameters2/5

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

  Schema coverage is 0%, so the description should compensate, but it never explains what release_id means or how it relates to the ranking. The schema only shows it is a required string. The description uses 'release' in its wording, providing only a weak hint, not clear parameter semantics.

  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 ('Rank'), a resource ('release components'), and a distinguishing criterion ('weighted risk of unresolved defects'). This clearly differentiates it from sibling tools like get_failed_tests or assess_release_readiness, which focus on different outputs.

  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 provided about when to use this tool versus the sibling tools. It does not mention alternatives, exclusions, or conditions under which another tool would be a better fit, leaving the agent to infer usage purely from the name and purpose.

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