Server Quality Checklist

Profile completionA complete profile improves this server's visibility in search results.

Latest release: v0.1.1
Disambiguation5/5
Every tool has a clearly distinct purpose, covering document generation, PDF manipulation, Excel, receipts, e-invoicing, and template management. Overlaps like generate_document vs compose_document are resolved by different input types (single vs multi-part).
Naming Consistency5/5
All tools follow a consistent verb_noun pattern with underscores, e.g., create_invoice, extract_receipt, merge_pdfs. No mixing of conventions like camelCase.
Tool Count2/5
At 40 tools, the server is significantly over-scoped for a typical document generation service. The breadth of features (PDF, Excel, receipts, e-invoicing) is excessive, making it harder to navigate.
Completeness5/5
The tool set covers the full lifecycle for document generation, PDF operations, Excel handling, receipt extraction, and e-invoicing (ZUGFeRD/XRechnung). Includes CRUD for templates, async jobs, and validation.
Average 3.7/5 across 40 of 40 tools scored. Lowest: 2.9/5.

How is the quality score calculated?

The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).

Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.

Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).

Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.

Tool Scores

Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations present. The description only states the return format (Base64-encoded PDF bytes). Lacks disclosure on idempotency, safety (read/write), authentication needs, size limits, or any side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Concise two-line description with structured Args/Returns. No wasted words, though it could be more informative about constraints.
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?
Tool is simple with one param and an output schema. Description covers input and output format. However, context signals indicate no nested objects or enums, so basic completeness is adequate, but missing details like supported HTML features or file size limits.
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?
One parameter 'html' described as 'HTML content to convert to PDF'. This adds context beyond the schema's type string. Schema description coverage is 0%, so description partially compensates.
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?
Clearly states verb 'Generate' and resource 'PDF from HTML content'. Distinguishes from siblings implicitly by specifying HTML input, but lacks explicit differentiation from similar tools like 'generate_pdf_from_markdown'.
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 'generate_pdf_from_markdown' or 'fill_pdf_form'. No exclusions or prerequisites mentioned.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description must disclose behavior. It states deletion but does not mention irreversibility, permissions required, or side effects like cascade deletes. Insufficient transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Concise two-sentence structure with clearly labeled Args and Returns. Efficiently communicates intent but could include more details within the same length.
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?
Given low complexity and presence of output schema, the description is minimally adequate. However, it does not specify return value details beyond a vague 'Confirmation message' or address error conditions like missing template.
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 0%, so description must compensate. It adds basic meaning by indicating that 'name' is the template's name, but does not explain format, case sensitivity, or uniqueness constraints.
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 'Delete a template by name,' using a specific verb and resource. It distinguishes this delete operation from sibling tools like list_templates and upload_template.
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 vs alternatives. Does not mention prerequisites, such as the template existing, or when deletion is appropriate.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full responsibility. It states that the tool returns metadata but does not disclose whether it is read-only, error handling behavior, or file format compatibility. The minimal information is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise with three sentences plus structured Args/Returns sections. It is front-loaded and avoids unnecessary words, earning its length.
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?
Given the output schema exists, the description adequately lists returned fields. However, it lacks information on error cases, file size constraints, or supported Excel versions. It is minimally complete for a simple inspection tool.
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 only parameter, excel_base64, is described as 'Base64-encoded Excel file', which adds basic meaning beyond the schema's title. However, it lacks specifics like file format, size limits, or encoding requirements. With 0% schema coverage, it adds some value but not enough.
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's purpose: inspecting an Excel workbook and returning metadata (sheet names, row/column counts, named ranges). This clearly distinguishes it from sibling tools that convert or generate Excel files.
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 excel_to_json or fill_excel_template. The description does not mention when not to use it or any prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
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 states the tool lists templates but does not mention authentication requirements, read-only nature, performance implications, or any side effects. This is minimal 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?
The description is extremely concise: two sentences with clear structure. Front-loaded with the action and resource, followed by return type. Every word is necessary.
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?
Given the existence of an output schema, the description does not need to detail return values. However, context about how the returned template info can be used with sibling tools (e.g., delete_template) is missing. The tool is minimally complete for a straightforward list operation.
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 input schema is empty with no parameters, and schema coverage is 100%. The description adds no parameter-level details, which is acceptable since there are none. Baseline score of 4 is appropriate.
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 clearly states the action 'List' and the resource 'uploaded document templates'. It also describes the return type as 'JSON array of template info objects'. However, it does not explicitly distinguish itself from siblings like list_certificates or list_fonts, but the resource name provides enough specificity.
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 on when to use this tool versus alternatives like upload_template, delete_template, or other list tools. The description does not mention prerequisites or context for usage.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided. Description only mentions return format, not behavior on invalid input, side effects, or read-only nature. Insufficient for a tool with no annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Very concise, two sentences plus return spec. Front-loaded with purpose. Could be slightly more structured but efficient.
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 single-param tool with output schema mentioned, but lacks error handling details and assumption of input validity. More context would improve 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?
Description adds that pdf_base64 must be base64-encoded and signed, which is useful beyond the schema's empty title. However, with 0% schema coverage, more detail would help.
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 verifies digital signatures in a PDF, using a specific verb and resource. It distinguishes from siblings like sign_pdf.
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 vs alternatives like sign_pdf or extract_text_from_pdf. It lacks context for agent decision-making.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description must disclose behavior. It mentions that the tool generates a document and returns base64-encoded bytes. However, it does not state whether any state is modified, if authentication is required, or any rate limits. The stateless nature is implied but not explicit.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise with a clear opening line and a list of parameters. It avoids redundancy but the list of args is necessary due to lack of schema descriptions. Could be more structured (e.g., separate sections for args and return).
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?
Covers inputs and output, but misses stating that at least one of html_content, markdown_content, or template_name must be provided (though schema marks all optional). No examples or usage notes. Output schema exists, so return values are assumed covered.
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 has no descriptions (0% coverage), so the description fully compensates by explaining each parameter's purpose. However, it does not clarify constraints like mutual exclusivity of html_content and markdown_content, or that a template_name requires a pre-uploaded template.
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 clearly states the tool generates documents with optional template, fields, and watermark. It lists inputs and output format. However, it does not differentiate from siblings like generate_pdf_from_html or generate_pdf_from_markdown, which perform similar tasks.
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 vs alternatives. For example, it doesn't clarify that if only HTML to PDF is needed, generate_pdf_from_html might be more appropriate. No prerequisites or exclusions mentioned.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It only states it returns a JSON array, lacking details about read-only behavior, permissions, or any side effects. This is minimal transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is very short (two sentences) and to the point, but it could be more structured by adding a brief note on return format or typical usage. It is concise but minimally informative.
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?
Given zero parameters and the presence of an output schema, the description is minimally complete. However, it does not explain if there are any filters, ordering, or limitations, leaving some gaps about the tool's behavior.
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?
There are no parameters, and schema coverage is 100%, so baseline is 4. The description does not need to add parameter info, and it does not, which is acceptable.
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 it lists 'all uploaded signing certificates' using the specific verb 'list' and resource 'signing certificates', which distinguishes it from sibling tools that deal with other document operations.
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 on when to use this tool vs alternatives, nor any prerequisites or exclusions. The lack of context about when listing certificates is appropriate makes it less helpful.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Lacking annotations, the description only states it returns a JSON array but provides no details on job lifecycle, filtering, pagination, or authentication requirements. Minimal behavioral disclosure for a read operation.
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?
Extremely concise: two sentences, no redundant information. Key purpose and return format are stated upfront.
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?
While an output schema exists and no parameters are needed, the description omits aspects like result ordering, error behavior, or scope (all jobs ever vs. recent). Sufficient for a basic understanding but incomplete for nuanced selection.
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?
No parameters exist, so schema coverage is trivially 100%. The description adds no parameter details, but none are needed. Baseline 3 applies as per rules.
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 the action (list) and resource (async receipt extraction jobs), distinguishing it from siblings like get_receipt_job (single job) and get_receipt_job_result (result retrieval).
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 get_receipt_job or extract_receipt_async. Explicit when-to-use or when-not-to-use is missing.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
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 for behavioral disclosure. It only states conversion to PDF/A and returns base64, but does not mention whether the conversion is lossy, if metadata is preserved, or any specific PDF/A version compliance.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is brief and to the point, using a docstring format that separates Args and Returns. It contains no extraneous information, though the formatting could be slightly more streamlined.
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 tool with one parameter and an output schema (indicated but not provided), the description is adequate but lacks details about the PDF/A version, error handling, or comparison to sibling archival tools like validate_zugferd.
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 description adds meaning to the single parameter 'pdf_base64' by clarifying it is a 'Base64-encoded PDF file.' The input schema only provides the title 'Pdf Base64', so the description fills a gap, though it could specify expected encoding format.
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 converts a PDF to PDF/A archival format. The verb 'Convert' and the resource 'PDF to PDF/A' are specific, distinguishing it from sibling tools like merge_pdfs or rotate_pdf.
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 vs alternatives such as validate_zugferd or extract_text_from_pdf. There is no mention of prerequisites (e.g., input must be a valid PDF) or situations where conversion is not appropriate.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided; description only states extraction and return of JSON. Does not disclose error handling, side effects, or requirements like file format validity.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Short description with clear Args/Returns sections. No redundant information, though could include more behavioral details without excessive length.
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?
Tool has output schema (implied by 'Returns JSON'), so return structure is covered. However, lacks usage context and behavioral traits, leaving gaps for a new user.
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?
Single parameter 'pdf_base64' has 0% schema description coverage; description adds meaning by specifying it is 'Base64-encoded ZUGFeRD PDF', compensating for the schema gap.
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 'Extract structured invoice data from a ZUGFeRD/Factur-X PDF', using a specific verb and resource. It distinguishes from siblings like validate_zugferd and parse_xrechnung by focusing on extraction.
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 (e.g., validate_zugferd might be used for validation). No mention of prerequisites or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
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 does not mention whether it is read-only, performance characteristics, size limits, or error handling beyond a straightforward page count. The minimal description leaves uncertainty.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise and well-structured with clear sections for args and returns. It avoids unnecessary words, though it could be more structured with examples or constraints.
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 covers the basic purpose and input meaning, but given no annotations and a simple single-parameter tool, it is adequate. However, it lacks information on output format details (even though an output schema exists) and edge cases, making it only moderately complete.
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?
Although schema description coverage is 0%, the description explicitly states 'pdf_base64: Base64-encoded PDF file,' adding semantic meaning beyond the schema's type string alone. This helps the agent understand the input format.
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 'Get the total number of pages in a PDF' clearly states a specific verb (get) and resource (page count of a PDF), distinguishing it from sibling tools like get_pdf_metadata or extract_text_from_pdf.
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, such as when only metadata is needed or when page count is part of a larger extraction task. The description does not provide usage context or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It states the tool signs a PDF but does not disclose whether the original file is modified, authentication requirements, rate limits, or error conditions. The output is described as a Base64-encoded signed PDF, but behavioral traits beyond the core action are absent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise, using a standard docstring format with clear sections for Args and Returns. It front-loads the purpose in the first sentence. No extraneous content, though it could be slightly expanded for clarity without becoming verbose.
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 covers the core operation and parameters, and the return type is specified. However, missing context such as certificate management (where to upload), permission requirements, and error handling leaves gaps. Given the tool has an output schema and no annotations, the description is adequate but not comprehensive.
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 description coverage is 0%, meaning the schema properties have no descriptions. The tool description compensates by explaining each parameter: 'pdf_base64: Base64-encoded PDF', 'certificate_name: Name of a pre-uploaded certificate', etc. This adds meaningful context beyond the schema's basic titles and types.
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 'Digitally sign a PDF with a PKCS#12 certificate.' This identifies the specific verb ('sign'), resource ('PDF'), and method ('PKCS#12 certificate'). No sibling tool performs signing, so it is well-differentiated.
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 mentions 'pre-uploaded certificate' but does not provide guidance on when to use sign_pdf versus alternatives, prerequisites (e.g., upload via list_certificates), or when not to use it. Sibling tools like list_certificates suggest preparation steps, but no explicit direction is given.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, and the description only states the basic operation. It does not disclose behavioral traits such as order preservation, error handling, or file size limits, which are important for a merge tool.
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 concise with two sentences in docstring format, no wasted words, and clearly structured with Args and Returns sections.
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 adequate for a simple merge tool, but lacks behavioral details like error handling or ordering. Since an output schema exists, return value explanation is not needed.
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 is 0%, but the description adds meaning by specifying that 'pdfs_base64' is a list of base64-encoded PDF files to merge, compensating for the schema's lack of detail.
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?

Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool vs alternatives like excel_to_csv or inspect_excel. The description only explains what it does, not when to choose it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It discloses the AI-based extraction and return format but omits limitations, error handling, or performance characteristics (e.g., image size, confidence thresholds).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise (4 sentences plus a bullet list of return fields) and front-loaded with the core purpose. It wastes no words, though the list could be integrated more smoothly.
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 complexity (AI OCR, structured output), the description covers input requirements and output fields comprehensively. However, it does not detail the exact JSON structure or error responses, and the output schema existence is not leveraged.
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?
With 0% schema description coverage, the description adds meaning to all three parameters: image_base64 as base64-encoded image, filename for format detection, content_type with MIME type defaults and PDF handling. This compensates well for the sparse schema.
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 extracts structured data from receipt/invoice images via AI, listing specific extracted fields. It distinguishes itself from sibling tools like extract_receipt_async (async variant) and extract_text_from_pdf (pure text extraction) by focusing on structured receipt data.
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 use for receipt/invoice images but lacks explicit guidance on when to use this tool versus alternatives like extract_receipt_async. No when-not conditions or prerequisites are mentioned.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It discloses that recalculate defaults to true and returns a base64 XLSX, but does not mention whether the original template is modified (it is not—returns new file), authorization needs, or error conditions. The information is present but could be more explicit about non-destructive nature and side effects.
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 clean docstring format (Args, Returns) with no wasted words. Each sentence earns its place: the opening sentence covers the core action, parameter list includes details, and return type is specified. It is front-loaded and easy to parse.
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?
Despite moderate complexity (template filling with cells and tables) and no annotations, the description covers parameters, defaults, and return value. It could mention input validation or template format requirements, but overall it is sufficient for an agent to use the tool correctly. The presence of an output schema is not utilized but the description compensates well.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, yet the description explains all four parameters with concrete examples: 'template_base64: Base64-encoded Excel template file', 'values: Cell values... key = cell ref like Sheet1!A1 or named range', 'tables: Table data... key = range name, value = row arrays', and the default for recalculate. This adds substantial meaning beyond the schema types.
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 ('Fill') and resource ('Excel template'), specifying 'with data at named cells and ranges'. This is unambiguous and distinguishes from siblings like 'generate_excel' which creates new files, or 'csv_to_excel' which converts CSV. The verb+resource combination is specific.
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 does not provide any guidance on when to use this tool versus alternatives. No context is given about prerequisites or typical use cases. For example, it could mention that this is for populating existing templates rather than generating from scratch. The absence of usage recommendations limits the agent's decision-making.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Given no annotations, the description must disclose behavior. It mentions the flatten option and that it returns a base64-encoded PDF, but lacks details on error handling, missing fields, or potential side effects. It does not contradict anything, as no annotations 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 concise (5 lines) and well-structured with Args and Returns. Every sentence adds value without redundancy, making it easy to parse quickly.
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?
While the description covers basic usage and return value, it misses edge cases like what happens if fields are empty or if the PDF lacks form fields. Given the tool's simplicity and the presence of an output schema, it is adequate but not exhaustive.
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 description coverage is 0%, so the description compensates by explaining each parameter (e.g., 'pdf_base64: Base64-encoded PDF with form fields'). This adds meaning beyond the schema's titles, though more detail (e.g., accepted formats for fields) would improve it.
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 'Fill form fields in a PDF,' specifying a precise verb and resource. This distinguishes it from sibling tools like merge_pdfs or generate_pdf_from_html, which serve different purposes.
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 explains the tool's function and parameters but does not explicitly state when to use it versus alternatives like inspect_pdf_form (to check fields) or generate_pdf_from_html (to create new forms). No when-not or comparative guidance is provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Discloses it returns Base64-encoded CSV but not behavioral traits like side effects or auth needs. Annotations absent, so description carries full burden; basic disclosure but gaps remain.
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?
Three-line description with clear purpose, Args, and Returns sections, no unnecessary words.
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?
Covers key aspects: input expected, output format. Could mention what DATEV-compatible entails or size limits, but adequate for a simple export tool.
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 description adds 'List of receipt extraction results (from extract_receipt)' to the receipts parameter, clarifying its source and type, which is valuable beyond the schema's bare definition.
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?
Clearly states the tool exports extracted receipt data as DATEV-compatible CSV, distinguishing it from sibling tools like export_receipts_xlsx.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Sufficient for a simple export tool with one parameter. Covers what, input, and output. Could mention no side effects, but overall complete.
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?
With 0% schema coverage, description compensates by explaining the parameter expects receipt extraction results from extract_receipt, adding semantic meaning beyond the raw schema.
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?
Clearly states the tool exports receipt data as XLSX format. Differentiates from sibling export_receipts_csv by specifying Excel workbook format and links to extract_receipt as data source.
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 usage after extract_receipt by specifying input source. Does not explicitly compare with CSV export or state when not to use, but context is clear enough for simple export.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
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 discloses the output format (JSON array of form field definitions) but does not mention side effects, permissions, error conditions (e.g., PDF without form fields), or performance constraints. The term 'inspect' implies read-only, but this is not explicit.
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 very concise: two sentences for purpose plus a neat Args/Returns section. Every line adds value, and the main action is front-loaded. No wasted words.
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?
The description covers input format, output structure, and core behavior. With an output schema present, it doesn't need to detail return values further. However, it omits behavior for edge cases like PDFs with no form fields, which could be clarified.
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 description adds meaning beyond the input schema by specifying that pdf_base64 should be a 'Base64-encoded PDF file with form fields,' which clarifies both the encoding and the requirement for form fields. The schema only provides a title.
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 inspects form fields in a PDF and returns their names, types, and values. It uses a specific verb ('inspect') and resource ('form fields in a PDF'), distinguishing it from sibling tools like fill_pdf_form or extract_text_from_pdf.
