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

No annotations are provided, so the description must fully disclose behavior. It explains that labor resources (RT_Labor) are flagged as over_allocated when planned hours exceed max_hours_per_year (default 2080), and results are sorted by planned hours descending. This adds meaningful behavioral context beyond structured fields, though it does not mention whether the tool is read-only or handles errors.

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 three concise sentences, front-loaded with the main purpose. No unnecessary words. It efficiently covers core behavior but could be slightly more structured (e.g., bullet points).

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 has two parameters, no output schema, and no annotations, the description covers the main analysis but omits details: return format (what fields are in the summary?), error behavior, and file_path meaning. It is adequate but not fully complete for an agent to invoke without assumptions.

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%, so description must compensate. It clarifies max_hours_per_year's default value and derivation (40 hrs/week x 52 weeks), adding value. However, file_path is left completely unexplained, relying on the parameter name alone. Overall, partial compensation for the coverage 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 summarizes resource utilization with planned/actual hours and costs, and specifies how over-allocation is flagged. It uses a specific verb ('summarize') and resource, distinguishing it from sibling tools like get_resources or get_resource_assignments.

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 the tool is for analyzing resource utilization but provides no explicit guidance on when to use it vs alternatives or when not to use it. No exclusion criteria or alternative tool names 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?

No annotations are provided, so the description must carry the full burden. It describes the checks performed (missing dates, resource assignments, etc.), implying read-only analysis. However, it does not disclose output format, error behavior, or performance considerations, leaving some behavioral aspects unclear.

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 two sentences plus a concise bullet list. The main purpose is front-loaded, and every element adds value without redundancy. It is efficiently structured for quick understanding.

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 complexity (5 parameters, no output schema, no annotations), the description covers the key checks and introduces threshold parameters. It could be more complete by noting the return format or file path requirement, but overall it sufficiently informs the agent for typical use.

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 input schema has 0% description coverage, so the description must compensate. It explains long_duration_days and high_float_days defaults and meaning, but does not describe file_path, project_id, or project_short_name. Partial coverage adds value but leaves gaps.

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 performs a DCMA-style schedule quality check on open/in-progress activities. It lists specific checks (missing predecessors, successors, long duration, high float, etc.), making the purpose precise and distinguishing it from sibling tools like get_critical_path or get_schedule_summary.

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 provides context (DCMA-style check on open/in-progress activities) but does not explicitly state when to use this tool versus alternatives, nor does it offer exclusions or prerequisites. The list of checks implies appropriate scenarios, but lacks direct 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 carries the burden. It mentions case-insensitivity and enriched return data, but does not disclose error behavior, permissions, or side effects.

For a simple retrieval with 2 params and no output schema, the description is mostly complete. Minor gap: no explanation of what 'file_path' represents.

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 adds meaning for 'task_code' (case-insensitive) but fails to describe 'file_path', leaving its purpose unclear.

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 verb 'Get', the resource 'full detail for a single activity', and the lookup key 'task_code', and distinguishes from sibling tools by specifying the returned enriched data.

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?

It implies use when needing full detail for a single activity but lacks explicit guidance on when to use this over siblings like get_relationships or get_resource_assignments.

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 implies a read-only listing operation but does not explicitly state that it does not modify data or require special permissions. The behavior is adequately described but not fully 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?

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?

Without an output schema, the description should explain return values but only mentions 'hours-per-period data' without elaboration. It also fails to clarify the input parameter or expected output format, leaving the agent underinformed.

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%. The description does not mention the sole parameter 'file_path' (type string, required), failing to add any meaning beyond the schema. The agent receives no guidance on how to use this parameter.

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 verb 'List' and the resource 'calendar definitions' with a specific scope 'in the XER file' and additional data 'hours-per-period'. This effectively differentiates it from sibling tools like 'get_resources' or 'get_activities'.

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?

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 key behaviors: only incomplete activities with total float <=0, sorted by early start ascending, and accepts either project_id or project_short_name. No annotations exist, so the description carries the full burden. It could include more about return format or error 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?

Three sentences, each providing essential information: what the tool does, sorting, and accepted filters. No redundant or unnecessary text.

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?

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?

With 0% schema description coverage, the description adds significant meaning for two of three parameters: project_id and project_short_name are explained as filters with types (numeric vs short name). file_path is required but not explained, 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 verb 'find' and the resource 'critical path activities' with specific criteria (total float <= 0, incomplete only). It distinguishes from sibling tools like get_project_activities which likely fetches all activities.

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?
