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

Provides a comprehensive 'Behavioral Transparency' section detailing read-only statelessness, idempotency, authentication, rate limits, error handling, and data privacy. This fully compensates for missing annotations.

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?

Well-structured with clear sections, but the parameter list is repetitive (16 lines with 'to analyze or process') making it verbose. Could be more concise without repeating the same phrase.

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?

Despite having an output schema, the description does not explain the output format or how the 12 requirements are evaluated. Parameter descriptions are weak, leaving gaps for a compliance assessment tool.

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 schema has 0% description coverage, but the description only adds generic phrases like 'The merchant level to analyze or process' for each of 16 parameters. This adds minimal meaning beyond the parameter name, failing to explain PCI-specific context like valid ranges for merchant_level.

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 explicitly states 'Evaluate an organization against all 12 PCI DSS 4.0 requirements', naming the specific standard and action. It clearly distinguishes from siblings like 'check_cardholder_data' and 'generate_saq' which are different tasks.

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?

Includes dedicated 'When to use' and 'When NOT to use' sections. Specifies use cases like assessment, gap analysis, and explicitly advises against substituting for legal counsel.

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 fully discloses side effects (none), authentication (optional), rate limits (10/day free), error handling, idempotency, and data privacy. This is thorough and honest.

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?

Well-structured with sections, but redundant: 'Behavior' and 'Behavioral Transparency' overlap. The Args section could be trimmed since schema shows titles. Lengthy for the content conveyed.

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?

Covers usage, behavior, and limitations thoroughly. With an output schema present, missing output explanation is acceptable. Lacks examples or clarification for boolean parameters, but overall complete for the tool's complexity.

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. However, the Args section merely repeats parameter names with generic phrases like 'The {name} to analyze or process,' adding no meaningful context beyond the schema's titles.

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 it analyzes cardholder data flow for PCI DSS compliance, with a specific verb and resource. It distinguishes from sibling tools by focusing on data flow analysis versus broader compliance assessment or documentation generation.

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?

Provides explicit 'When to use' and 'When NOT to use' sections, covering audit, gap analysis, and documentation. However, it does not directly compare with sibling tools or specify when to choose alternatives.

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 provided, the description thoroughly covers behavioral traits: read-only (no side effects), authentication requirements, rate limits (10/day free), error handling, idempotency, and data privacy. All traits beyond what annotations would typically provide.

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 well-structured with clear sections (Behavior, When to use, Args, Behavioral Transparency) and is front-loaded with the core purpose. While slightly lengthy, each section adds value without 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?

Given the tool has 4 parameters, no annotations, and an output schema, the description provides comprehensive coverage of behavior, limitations, and usage guidance. It could clarify the output format or template content, but the presence of an output schema mitigates this gap.

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 description must compensate. The 'Args' section only repeats parameter names and types ('organization_name (str)') without adding meaningful constraints, examples, or descriptions of valid values. Also fails to mention the 'caller' parameter from the schema.

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 'Generate a PCI DSS Self-Assessment Questionnaire template,' which is a specific verb and resource. It distinguishes from sibling tools like assess_pci_compliance or vulnerability_scan_check, which have different purposes.

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 includes explicit 'When to use' and 'When NOT to use' sections, providing clear context for when this tool is appropriate and warning against using it as legal advice. This helps the agent decide between alternatives.

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?

Despite no annotations, the description thoroughly covers side effects (read-only, stateless), authentication, rate limits, error handling, idempotency, and data privacy. This is exemplary beyond typical descriptions.

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?

Well-structured with clear sections and front-loaded purpose. However, the 'Behavior' and 'Behavioral Transparency' sections overlap slightly, and the 'Args' section is verbose without adding value.

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?

Covers many aspects: purpose, behavior, usage guidelines, error handling. Missing high-level output description (though output schema exists). Parameter explanations are weak. Overall adequate but not fully comprehensive given tool complexity.

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 the description must compensate. However, the 'Args' section provides only generic restatements of parameter names (e.g., 'The has segmentation to analyze or process'), adding negligible semantic value. No explanation of how parameters affect output.

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 starts with a clear verb+resource: 'Check network segmentation for PCI DSS scope reduction.' It is distinct from siblings like assess_pci_compliance (broader) and vulnerability_scan_check (different focus).

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?

Includes 'When to use' and 'When NOT to use' sections, but they are generic and do not explicitly differentiate from sibling tools. Provides context for compliance use but lacks comparative 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 full burden and excels. It explicitly states read-only, stateless, idempotent, safe, rate limits (free/pro), authentication needs, error handling, data privacy, and structured error responses. This is comprehensive and exceeds typical disclosure.

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 well-organized with sections but verbose. The 'Behavioral Transparency' section largely repeats the earlier 'Behavior' section. Parameter descriptions are repetitive and uninformative, making the text longer than needed without added value.

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?

While behavioral transparency is thorough and output schema exists, the weak parameter semantics and generic descriptions leave a significant gap. Agents may not understand how to properly use the 9 optional parameters, harming completeness for a tool with no required inputs.

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% (schema has no descriptions). The description's 'Args' section lists all 9 parameters but provides generic definitions ('The ... to analyze or process') that add no real meaning beyond parameter names and types. This fails to clarify role or valid values, leaving agents guessing.

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 explicitly states the tool evaluates vulnerability scanning compliance per PCI DSS ASV requirements, which is a specific verb-resource pair. It distinguishes from siblings like assess_pci_compliance (broader compliance) and network_segmentation_check (different focus).

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 includes 'When to use' and 'When NOT to use' sections, providing clear context for compliance assessment, gap analysis, and documentation generation. It warns against substituting legal advice but does not explicitly compare to sibling tools for when to choose this over others.

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