Server Quality Checklist
Latest release: v0.3.0
- Disambiguation5/5
Each tool has a clearly distinct purpose: searching experiments vs. files, downloading batches vs. specific files, tracking vs. comparing, etc. No two tools perform overlapping functions, and descriptions clearly differentiate them.
Naming Consistency5/5All 20 tools follow a consistent 'encode_verb_noun' pattern in snake_case. Verbs like get, list, search, track, compare are used uniformly, making the tool surface predictable and easy to navigate.
Tool Count5/520 tools is well-suited for the ENCODE domain, covering discovery, retrieval, tracking, comparison, citations, provenance, and credentials. Each tool earns its place without being overwhelming.
Completeness5/5The toolkit covers the full lifecycle: data exploration (search, facets, metadata), retrieval (download, batch download), local management (track, list, export, summarize), comparison, citations, references, provenance tracking, and credentials. There are no obvious gaps for a comprehensive ENCODE workflow.
Average 4.6/5 across 20 of 20 tools scored. Lowest: 3.8/5.

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
- Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly, not destructive, and idempotent. The description adds context about return structure and export capabilities but does not disclose additional behavioral traits beyond the annotations. No contradictions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
Well-structured with sections for purpose, usage, args, and returns. Moderately concise; every sentence adds value. Could be slightly tighter but effective overall.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (2 optional parameters) and the presence of an output schema, the description provides sufficient context: lists return fields, export options, and a usage section. No major gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Despite 0% schema description coverage, the description's 'Args' section explains both parameters in detail, including the meaning of accession and the available export_format enum values. This compensates fully for the lack of schema descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool gets publications and citations for tracked experiments, listing returned fields (authors, journal, DOI, PMID) and export formats. However, it does not explicitly differentiate from a potentially similar sibling tool 'encode_get_references', which may serve a similar purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Includes a dedicated 'WHEN TO USE' section and mentions related tools. Provides guidance on export formats for reference managers. Lacks explicit exclusions or alternatives for when this tool should not be used.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (one parameter, rich annotations, output schema exists), the description fully explains the return value (files, quality metrics, controls, replicates, audit status). It covers all necessary context for proper invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Only one parameter (accession) exists, and schema coverage is 0% (no description in schema). The description provides an example ('ENCSR133RZO') and explains it is an ENCODE experiment accession, adding meaning beyond the schema's title. While schema coverage is low, the description compensates well.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves full details for a specific ENCODE experiment by accession ID, using precise verbs ('Get full details') and resource ('specific ENCODE experiment'). It distinguishes from siblings like encode_list_files (lists files) and encode_compare_experiments (comparison), so the agent can select it correctly.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description includes a 'WHEN TO USE' section specifying when to use this tool ('when you have a specific accession and need full details including files, quality metrics, and audit status'). It also lists related tools, but does not explicitly state when not to use it or alternatives. The guidance is clear but lacks exclusion conditions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Describes creating a provenance record, consistent with annotations (readOnlyHint=false, destructiveHint=false). Idempotency hinted by idempotentHint=true but not elaborated; otherwise transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
Well-structured with sections and bulleted args. Slightly verbose but every sentence contributes to understanding.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Covers all necessary aspects: purpose, usage, parameters, return value (output schema exists), and context relative to siblings. No gaps evident.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, but the description provides thorough explanations for all 6 parameters with examples, adding substantial value over the bare schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Log a file you've derived from ENCODE data for provenance tracking' with specific examples. It distinguishes from siblings like encode_get_provenance and encode_download_files.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly includes 'WHEN TO USE' and 'RELATED TOOLS' sections, guiding the agent on appropriate context and alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, openWorldHint=true. The description adds useful behavioral context, such as pagination via limit/offset, default status 'released', and that it returns JSON with results, total count, and pagination info. No contradictions, and the description enhances transparency beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with a clear opening, examples, common values, usage guidance, and parameter list. It is front-loaded with purpose. However, it is somewhat lengthy due to the many examples and parameter details, but this is justified by the need to compensate for zero schema coverage. Nearly all sentences earn their place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (21 parameters, no required fields, no enums, has output schema), the description is remarkably complete. It explains the return format (JSON with results, count, pagination), provides usage examples, lists common values, and gives guidance on when to use alternative tools. The output schema existence reduces the need to detail return values, but the description handles it well.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, but the description provides detailed explanations for all 21 parameters, including common values, defaults, and usage examples. Examples like 'assay_title="Histone ChIP-seq", organ="pancreas", biosample_type="tissue"' illustrate how to combine parameters effectively. This fully compensates for the lack of schema descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description includes explicit 'WHEN TO USE' guidance: 'Use as the primary entry point when users want to find experiments. Start with encode_get_facets if unsure what filters to use.' It also lists related tools, providing clear context for when to use this tool versus alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, openWorldHint=true. The description adds detail about returning faceted counts and that it is exploratory, not modifying data. No contradictions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with a header, usage guidelines, examples, and return type. Every sentence adds value, and it is front-loaded with the purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
