Server Quality Checklist

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

Latest release: v0.1.22
Disambiguation4/5
Most tools have clearly distinct purposes (pipelines, indexes, workspaces, secrets, components, templates, etc.), and descriptions are detailed. However, the three search_pipeline variants (plain, with_filters, with_params) overlap in capability, and list_search_history vs list_pipeline_search_history could be confused.
Naming Consistency4/5
The vast majority of tools follow a consistent verb_noun snake_case pattern (list_*, get_*, create_*, deploy_*, validate_*, etc.). Minor deviations exist such as grep_object_store, sed_object_store, and yq_object_store (Unix-command style) and occasional get/list alternations (e.g., get_custom_components vs list_custom_component_installations).
Tool Count2/5
With 50 tools, this is a very large surface for an MCP server. While the scope is broad (pipelines, indexes, workspaces, secrets, components, templates, traces, object store), the count exceeds the 25+ threshold that is considered too many, making it heavy for agents to navigate.
Completeness3/5
The tool set covers a wide range of operations: create/read/update/deploy for pipelines and indexes, plus workspaces, secrets, components, templates, and search history. Notable gaps include the absence of delete operations for any resource (pipelines, indexes, workspaces, secrets) and lack of create_secret, which limits full lifecycle management.
Average 4/5 across 50 of 50 tools scored. Lowest: 2.4/5.

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?
Without annotations, the description carries the full burden. It discloses two key behaviors: finalizing the previous draft with an incremented version number, and that the output is automatically stored in the object store. However, it does not explain potential irreversibility (finalization may be destructive) or required permissions. The side effects are mentioned but not thoroughly explored.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness2/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is verbose but includes irrelevant and incorrect examples (e.g., 'data', 'threshold' parameters) and a repetitive explanation about object references. The core purpose and side effects are front-loaded, but the extraneous content harms conciseness. Every sentence does not earn its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool modifies state and returns an object store reference, but the description does not cover edge cases (e.g., what if no previous draft exists? what if version is already a draft?). With no output schema, the return format is only partially described ('formatted preview'), lacking details. The incorrect examples further reduce completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so the description must fully explain parameters. It clarifies version_id as a UUID and pipeline_name as the name, but the examples are grossly incorrect, suggesting parameters 'data' and 'threshold' that do not exist in the schema. This undermines the parameter description and could mislead an agent.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose3/5
Does the description clearly state what the tool does and how it differs from similar tools?
The first sentence clearly states the tool restores a non-draft pipeline version to be editable as a new draft with side effects. However, the examples that follow are contradictory, using parameters 'data' and 'threshold' that do not match the actual schema, which confuses the intended purpose. The verb 'restore' and resource 'pipeline version' are specific, but the incorrect examples lower clarity.
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 specify when to use this tool versus alternatives like patch_pipeline_version. It lacks any guidance on prerequisites (e.g., ensuring the version is non-draft) or when not to use it. The sibling tools include patch_pipeline_version for editing drafts, but no comparison is provided, leaving an agent without context for selection.
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 output is automatically stored with object ID and returns a preview, which is useful. However, no annotations are provided, and the description does not cover potential side effects or authorization needs.
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?
Purpose front-loaded, but includes redundant docstring-style param/return lines and mismatched examples. Could be more concise and accurate.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, 0% schema coverage, and many siblings, the description omits crucial context like YAML structure, prerequisites, error handling, and differentiation from pipeline versioning tools.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%. Description adds minimal info (pipeline name and YAML config), but the examples are mismatched, referencing non-existent parameters 'data' and 'threshold', which confuses. No explanation of YAML 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?
Clearly states verb 'creates' and resource 'pipeline' within deepset workspace. Distinguishes from siblings like create_index or create_workspace.
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?
Provides examples and mentions object references for parameter passing, but lacks explicit guidance on when to use this tool versus alternatives like create_pipeline_version or deploy_pipeline.
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 carry behavioral burden. It discloses that output is automatically stored, provides a formatted preview with an object ID, and suggests using object store tools for nested properties. However, it does not mention error handling beyond 'error message string', or performance implications.
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 a single paragraph with docstring-style lines. It is moderately concise but has slight redundancy (object ID mentioned twice). Front-loading is acceptable.
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 no output schema and 0% schema coverage, the description covers the parameter well and explains output storage and referencing. However, it lacks details on what the returned ComponentDefinition model contains, which could aid agent understanding.
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 provides detailed semantics for the 'component_type' parameter, including a fully qualified example. This adds significant meaning beyond the bare schema.
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 returns the definition of a specific Haystack component, with a required fully qualified component type. It implicitly distinguishes from sibling 'search_component_definitions' by focusing on a single definition rather than searching, though not explicitly.
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?
There is no guidance on when to use this tool versus alternatives like search_component_definitions. The description gives an example parameter but lacks when-to-use or when-not-to-use context.
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?
The description discloses that the output is stored and returns an object ID for further use, implying a read operation. However, with no annotations, it does not explicitly confirm no side effects or state the exact behavior beyond output handling.
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 adequate but contains some redundancy (e.g., mentioning logs twice). It is structured as a paragraph but could be more streamlined.
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 no parameters or output schema, the description sufficiently explains the output format and how to use it with object store tools. It lacks details on error scenarios but covers the essentials.
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?
No parameters are defined, so the schema provides full coverage. The description adds value by explaining the output storage and object ID usage, meeting the baseline for a zero-parameter tool.
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 retrieves logs from the latest custom component installation. The name and description are consistent, but no explicit differentiation from sibling tools is provided.
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 includes instructions on using the output with object store tools but lacks guidance on when to choose this tool over alternatives like list_custom_component_installations or get_custom_components.
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 discloses the return format (formatted preview with object ID) and mentions automatic storage for cross-function reference. However, it lacks details on error handling or rate limits.
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 moderately concise but includes a Python-docstring style for parameters that adds length without improving clarity for an AI agent.
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 pagination, return format, and object ID usage, compensating for lacking output schema. However, it omits error conditions and authorization requirements.
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?
Despite 0% schema description coverage, the description explains 'limit' as max per page and 'after' as cursor for pagination, adding meaning beyond the schema's type and defaults.
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 'List custom component installations' as the action and resource, which is distinct from sibling tools like 'list_component_families' or 'list_indexes'. However, it does not explicitly differentiate from siblings.
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 provides no guidance on when to use this tool versus alternatives, missing exclusion criteria or context about pagination limits.
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 provided, the description carries the full burden. It discloses behavioral traits such as automatic storage of output and returning an object ID for further reference, but it does not explicitly state read-only safety or any side effects. This adds moderate value beyond a simple list.
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 somewhat verbose with redundancy in the first two sentences. It is structured with a clear purpose sentence followed by output details, but could be more concise. The information about object ID usage is useful but could be integrated more tightly.
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 simplicity of the tool (0 parameters, no output schema, no annotations), the description covers the purpose, output fields, and how to use the result (object ID). It is fairly complete, though it could mention potential limitations like pagination or authentication requirements.
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 zero parameters, so schema coverage is 100%. The description adds meaning by describing the output structure (fields like name, ID, languages, idle timeout) and how to use the object ID. This justifies a score above the baseline of 3, but not 5 as it could be more specific.
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 that the tool retrieves a list of all workspaces available to the user, using specific verb 'Retrieves' and resource 'list of all workspaces'. It also enumerates the per-workspace fields (name, ID, supported languages, idle timeout). However, it does not explicitly differentiate from sibling tools like get_workspace or other list tools, settling for a score of 4.
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 provides no explicit guidance on when to use this tool versus alternatives such as get_workspace or other list tools. It merely states what it does without contextual advice, resulting in a low score.
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 description carries full burden. It describes the tool as searching documentation and returning formatted results, which is sufficient for a read-only search tool. However, it does not disclose potential limitations like maximum result count or source freshness.
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 two paragraphs and a parameter docstring. It front-loads the main purpose and then elaborates. The docstring adds structure but could be shortened.
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 no output schema and one parameter, the description covers the basic purpose and usage. However, it lacks details about how results are formatted, pagination, or error handling, which would be helpful for an agent.
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 description includes a brief docstring for the query parameter, adding meaning beyond the input schema which has no description. However, schema coverage is 0%, so description partially compensates. It explains what the query is used for but does not detail expected format or examples.
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 searches deepset documentation for information about features, API usage, best practices, and troubleshooting guides. It distinguishes from sibling tools like search_pipeline or search_templates by specifying documentation domain.
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 mentions using it to look up specific functionality or help users, but does not explicitly state when not to use it or provide alternatives. It implies usage context but lacks exclusion guidance.
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 the pre-execution deployment check and that output is stored with an object ID. However, no annotations are present, and the description does not cover permissions, rate limits, or read-only nature. Adequate but not comprehensive.
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?
Description is somewhat verbose with redundant phrasing (e.g., 'Searches using...' and 'Uses the specified pipeline...'). The docstring format is structured but could be trimmed.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Lacks details on return value structure; only says 'search results or error message' and mentions a formatted preview. Without an output schema, the description should specify result fields or types. Incomplete for a search 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?
Schema coverage is 0%, but the description compensates by explaining all three parameters: pipeline_name, query, and filters (with link to syntax). Adds meaningful context beyond the schema's type and 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?
Description clearly states the tool performs a search using a pipeline with filters (verb+resource). It distinguishes from siblings like 'search_pipeline' and 'search_pipeline_with_params' by explicitly mentioning Haystack filter syntax and the pipeline deployment check.
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 (e.g., 'search_pipeline' or 'search_pipeline_with_params'). Does not mention when not to use or prerequisites beyond the deployment check.
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?
The description discloses that the output is automatically stored and can be referenced in other functions, and that it returns a formatted preview with an object ID. It also explains object reference syntax. Since there are no annotations, this behavioral context is valuable.
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 structured with a param/returns block and examples, but it is somewhat verbose. It could be more concise by removing the docstring-style formatting and redundancy about object references.
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 a single parameter and no output schema, the description covers the input, return format, object references, and output storage. However, it lacks details on error handling, expected success/failure conditions, and potential validation outcomes.
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 schema by explaining the yaml_configuration parameter ('The YAML configuration to validate') and describing the object reference pattern. With 0% schema description coverage, this compensation is significant.
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 validates pipeline YAML configuration against the deepset API. It specifies the resource (pipeline YAML) and action (validate), giving a clear purpose. However, it does not explicitly distinguish from sibling tools like validate_index.
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 provides examples of calling the tool but gives no guidance on when to use it versus alternatives. It lacks explicit context for when to use or not use this tool, and does not mention when it should be preferred over other tools.
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 explains the basic input mechanics. It does not disclose any behavioral traits like read-only nature, side effects, rate limits, or error conditions.
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 front-loaded with the purpose and includes efficient param documentation. Every sentence adds value, though it could be slightly more concise.
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 fetch tool, the description covers input semantics well but lacks output format details and does not differentiate from similar tools. Context for choosing this tool over siblings is missing.
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?
Despite 0% schema description coverage, the description thoroughly explains the object_id format (@obj_001), path format (dot or bracket notation), and provides complete usage examples, fully 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.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool fetches an object from the object store, with specific examples for object_id and path. However, it does not differentiate from siblings like get_slice_from_object_store or grep_object_store.
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 provides scenarios: fetching by id and fetching nested paths. It does not include when not to use or mention alternatives, leaving usage guidance implicit.
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 carries full burden. It mentions pagination via 'after' cursor, auto-storage of output, and formatted preview with object ID. However, it lacks details on error handling, rate limits, or any destructive aspects. The read-only nature is implied but not stated.
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?
Description includes a clear one-liner for purpose, parameter docs, and then extra sentences about auto-storage and object ID usage. While informative, it could be more concise by integrating the storage note with the return description.
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 no output schema, the description explains the return format (formatted preview with object ID) and pagination. However, it does not describe the schema of each version or cover error scenarios, making it adequate but not thorough.
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 for parameters (coverage 0%), so the description adds essential meaning: 'pipeline_name' as the target pipeline and 'after' as a cursor UUID for pagination. This compensates well 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 the action 'Lists all versions of a pipeline' and specifies ordering 'by version number descending (newest first)'. It distinguishes this from siblings like get_pipeline_version (single version) and list_pipelines (list pipelines).
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 explicit guidance on when to use this tool versus alternatives such as get_pipeline_version, search_pipeline_with_filters, or list_pipeline_search_history. The description does not mention prerequisites or when not to use 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?
With no annotations provided, the description carries full transparency burden. It discloses that results are automatically stored, returns an object ID, and can be used with object store tools. However, it does not mention side effects, authorization requirements, rate limits, or whether the operation is read-only. It provides moderate behavioral insight but leaves gaps.
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 moderately concise but contains some redundancy, e.g., mentioning the output is stored and then explaining how to use the ID. It is structured with a clear first sentence and parameter docs, but could be tightened by removing repeated advice about using the object ID.
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 search tool with two parameters and no output schema, the description covers purpose, parameters, output format (preview + object ID), and integration with object store. However, it lacks details on error conditions, search semantics, and what fields appear in the preview. Given the tool's simplicity, it is minimally complete but leaves room for improvement.
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 has 0% description coverage (only titles). The description compensates by explicitly documenting both parameters: 'query' as the search query and 'top_k' as maximum results (default 5). This adds meaning beyond the schema's bare titles. While it could include examples or constraints, it provides adequate semantic clarity for an agent.
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 searches for components based on name or description using semantic similarity. This verb-resource pair is distinct from sibling tools like 'search_pipeline' or 'search_docs', which target other entities. The inclusion of 'using semantic similarity' adds 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?
The description provides no guidance on when to use this tool versus alternatives such as 'get_component_definition' or other search tools. It does not mention prerequisites, limitations, or cases where another tool would be more appropriate. This lack of usage context is a significant gap given the large number of sibling tools.
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?
Since no annotations are provided, the description carries the full burden. It discloses key behaviors: it checks if the pipeline is deployed before executing, stores results in an object store for later reference, and returns a formatted preview with an object ID. It also notes potential error messages. This level of detail helps an AI agent understand side effects and output format, though it does not mention rate limits or authentication needs.
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 verbose and contains redundancy, e.g., the first two sentences both state the same idea: 'Searches using a pipeline with params.' and 'Uses the specified pipeline to perform a search...'. It also includes a docstring-style parameter list that could be integrated more succinctly. While it is clearly structured, it could be tighter.
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 lack of output schema and low schema coverage, the description provides comprehensive context: it explains the pre-execution check, the return format (error messages or object ID preview), and the object store integration. It also hints at using object store tools to view nested properties. This covers the essential aspects needed for an AI agent to use the tool effectively.
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 compensates well. It defines each parameter: pipeline_name ('Name of the pipeline to use'), query ('The search query to execute'), and params ('parameters to customize the search'). For params, it adds that arbitrary parameters are allowed and that filters can be specified under the 'filters' key, with a link to the Haystack filter syntax. This adds significant value beyond the bare schema.
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's purpose: 'Searches using a pipeline with params.' It specifies the verb 'searches' and the resource 'pipeline with params', making the function distinct. However, it does not explicitly differentiate from sibling tools like search_pipeline and search_pipeline_with_filters, which could confuse an AI agent when selecting among them.
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 provides no explicit guidance on when to use this tool versus alternatives. It does not mention conditions for choosing this tool over search_pipeline or search_pipeline_with_filters, nor does it explain any prerequisites. The only implicit hint is the mention of arbitrary params, but this is not framed as a usage criterion.
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 that parameters accept object references and that output is stored and returns an object ID, but does not mention destructive behavior, auth needs, or error handling.
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 well-structured with clear sections: purpose, parameter descriptions, support for references, examples. It is front-loaded and moderately concise, though the examples are somewhat lengthy.
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 3 parameters, no output schema, and no annotations, the description covers basic purpose, parameters with reference support, and output format. However, it misses error conditions, prerequisites, and details on the YAML configuration.
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 the description must add value. It lists each parameter with a brief explanation and mentions object reference support, but lacks details like what a valid YAML configuration entails or constraints on index_name.
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 creates a new index within the deepset platform workspace, differentiating it from siblings like update_index or validate_index.
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?
No explicit when-to-use or when-not-to-use guidance is provided. Usage is implied by the tool's basic purpose, but it does not distinguish from alternatives like update_index or validate_index.
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?
No annotations are provided, so the description carries the burden. It discloses that the output is automatically stored, returns a formatted preview with an object ID, and can be passed to other functions. It also mentions error messages. This is valuable beyond the schema, though it stops short of stating permissions or explicit read-only safety.
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 moderately sized but contains redundancy; two sentences about using the object ID could be merged. The use of `:param` and `:returns` is conventional, but the instructions are somewhat scattered.
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 one-parameter tool, it covers the return format and how to use the object ID, but it lacks explicit usage guidance versus siblings and does not elaborate on error conditions beyond a generic message. The overall context is adequate for basic use but not comprehensive.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With schema description coverage at 0%, the description must compensate. However, it only restates the parameter name ('The name of the pipeline to fetch') and adds 'unique', which adds little meaning beyond the schema. No format, constraints, or examples are provided.
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 'Fetches information for a specific pipeline' and identifies the resource by the unique `pipeline_name`, distinguishing it from sibling tools like `list_pipelines` (fetching all) and `get_pipeline_version` (a version-specific resource).
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?
It implies usage when you have a specific pipeline name, but does not explicitly mention when to prefer this over alternatives, nor does it state exclusions. The guidance about using object store tools is about post-processing, not tool selection.
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 must convey behavior. It states the secret value is not returned, output is stored, and an object ID is returned for referencing. It lacks details on auth needs, rate limits, or error handling.
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 moderately concise but contains redundant phrasing (e.g., 'Use this tool to get information about a specific secret' reiterates the purpose). It front-loads the core action but could be tighter.
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 no annotations, the description covers retrieval, security nuance, and output format. However, it omits specifics like what metadata is returned, error case handling, and explicit object store usage instructions.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%. The description adds minimal semantics by calling secret_id 'the unique identifier of the secret to retrieve,' which is a slight improvement over the schema's bare title. Given the low coverage, more elaboration is needed.
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 function: 'Retrieves detailed information about a specific secret by its ID.' It differentiates from siblings like list_secrets by emphasizing 'specific secret' and 'by ID'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly says when to use: 'Use this tool to get information about a specific secret when you know its ID.' It also notes that the secret value is not returned for security reasons, implying alternative uses for other data.
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 carries full burden. It discloses return behavior (validation result on failure, stored object ID) and how to use the object ID. However, it does not mention destructive actions, auth requirements, or side effects of deployment.
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 includes docstring-style parameter and return sections, making it somewhat lengthy (6 sentences). Information is front-loaded, but could be more concise.
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 no annotations, 0% schema coverage, and no output schema, the description provides parameter meanings, return value with object ID usage, and partial behavioral context. It lacks prerequisites (e.g., pipeline existence, permissions) but is fairly complete for deployment.
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%, but the description fully explains both parameters: pipeline_name is the name of the pipeline, version_id is optional and defaults to latest non-draft version. This adds significant meaning beyond the 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 'Deploys a pipeline to production,' which identifies the specific action and resource. It is distinct from sibling tools like 'create_pipeline' (which creates) and 'validate_pipeline' (which only validates).
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 guidance on when to use this tool versus alternatives (e.g., deploy_index, validate_pipeline). It only explains behavior on failure but no context for appropriate use.
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?
The description discloses return type (ComponentDefinitionList model or error string), automatic storage with object ID, and how to use the object ID for further operations. Since no annotations are provided, this carries the burden well, though it could mention idempotency or auth requirements.
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 first sentence states the purpose. Subsequent sentences add value about object store integration. Could be slightly shorter, but it's well-structured and front-loaded.
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?
For a parameterless tool with no output schema, the description explains return model, error possibility, and object navigation. It's nearly complete but lacks distinction from sibling get_component_definition.
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 100% vacuously. Baseline is 3; description adds no param info but correctly focuses on output behavior.
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 begins with a specific verb and resource: 'Get a list of all installed custom components.' This clearly distinguishes it from siblings like get_component_definition (single component) and list_custom_component_installations (installations list).

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 somewhat verbose with repetition (e.g., 'Returns search results' and 'Returns a formatted preview'). It could be more concise by merging statements, but it is front-loaded with the core purpose.
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 two simple parameters and no output schema, the description covers the main behavior: deployment check, object ID storage, and integration hints. Lacks details on error types or pagination, but it is mostly complete for a basic search 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 input schema has 0% parameter description coverage, but the description explicitly documents each parameter with clear meaning (pipeline_name, query). Although not exhaustive on formats, it sufficiently compensates for the schema gap.
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 it searches using a pipeline with a given query. However, it does not differentiate from sibling tools like search_pipeline_with_filters or search_pipeline_with_params, which might have more specific 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 implies usage when a pipeline is available and deployed (checks status) but does not provide explicit guidance on when to use this tool versus alternatives. No exclusions or preferred contexts 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?
The description indicates the return type (string representation) but does not disclose error handling (e.g., invalid indices) or side effects. With no annotations, more details are expected.
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?

Usage Guidelines2/5
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 versus alternatives such as get_from_object_store or grep_object_store; usage context is only implied by the description.
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?
Even without annotations, the description discloses key behavioral traits: the output is automatically stored, a preview with an object ID is returned, and the ID can be used with object store tools or passed to other functions. This goes beyond just 'fetches template' and aids the agent in understanding the return format 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.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?

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?
With no annotations provided, the description carries full burden. It discloses pagination via 'after' parameter and 'next_cursor' response, and explains that output is automatically stored and can be referenced via object ID. However, it does not mention rate limits or authorization needs, which are less critical for a read-only list endpoint.

Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is moderately concise but includes a param docstring that could be integrated more tightly. It has some redundancy (mentions 'index_name' twice) and advice that, while helpful, adds length. Could be streamlined.
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?
There is no output schema, so the description explains the return format (formatted preview with object ID) and how to use it (object store tools). This makes the tool usable, though it could detail the configuration content slightly more. Overall sufficient for a simple fetch 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?
Schema description coverage is 0% (no descriptions in schema), but the description includes a ':param index_name: Unique name of the index to fetch.' line, adding meaning beyond the type alone. It compensates well 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 uses 'Fetches detailed configuration information for a specific index,' clearly stating the action and resource. It distinguishes from siblings like list_indexes (which lists all) and other get_* tools by specifying the target is a single index.

Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without annotations, the description carries full burden. It discloses that the output is a list with names/IDs, is automatically stored, includes pagination details (limit, after cursor), and provides a formatted preview with an object ID. No mention of side effects, but reasonable for a read-only listing operation.
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 no unnecessary repetition. It is front-loaded with purpose. Minor redundancy in docstring formatting, but overall each sentence contributes useful information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simplicity of the tool (2 parameters, no output schema, no annotations), the description fully covers purpose, parameters, output behavior, and integration with object store. It is complete for an effective listing operation.
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 has 0% coverage, but the description explicitly documents both parameters: 'limit: Maximum number of secrets to return (default: 10)' and 'after: The cursor to fetch the next page of results'. This adds meaningful context beyond the raw schema types and defaults.
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 'Lists all secrets available in the user's deepset organization' with a specific verb and resource. It distinguishes from sibling 'get_secret' by implying the action covers all secrets.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description notes it's useful 'for getting an overview of all secrets before retrieving specific ones,' providing a when-to-use hint. It also explains how to use the output (object ID for further operations), but does not explicitly mention when not to use it or name alternatives like get_secret.
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?
With no annotations, the description carries the full burden. It discloses the return format (markdown content) and error behavior (message listing available skills if not found), which gives useful behavioral expectations. It does not mention side effects or permissions, but for a read-only skill loader this is adequate.
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 well-structured with an opening definition, usage sentence, bulleted skill list, and param/returns sections. The custom-code skill explanation is somewhat lengthy but provides valuable context, earning its place. No wasted words overall.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a one-parameter read tool with no output schema, this description is complete: it covers purpose, when to use, parameter semantics, return value, and error handling. The inclusion of the available skill list makes it self-contained. No gaps remain.
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 coverage is 0%, so the description fully compensates. It explicitly states the parameter meaning ('The name of the skill to load') and provides an enumerated list of valid values (custom-code), effectively serving as an inline enum. This gives the agent everything needed to populate skill_name correctly.
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 opens with a specific verb+resource: 'Loads the full content of a bundled skill guide by name.' This clearly distinguishes the tool from siblings like get_template or search_templates by focusing on skill guides rather than templates or generic docs. The additional detail about available skills further clarifies its purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
It explicitly says 'Use this tool to read the step-by-step instructions for a specific skill supported by this server,' providing clear context for when to invoke it. It also lists a concrete skill with trigger scenarios, but it does not explicitly mention when not to use it or name alternative tools, so it falls short of a 5.
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?
No annotations are provided, so the description carries full burden. It explains that output is stored as an object reference with an ID, how to use references in inputs, and that error messages are returned. However, it lacks details on side effects, authentication needs, or specific error conditions.
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

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 4 parameters and no output schema, the description provides thorough guidance on inputs, output format (object reference), usage patterns with references, and return structure. It is complete enough for correct invocation.
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%, so description compensates fully. Each parameter is explained with purpose, format, and examples. It notes that input_types can be inferred and explains object reference syntax. This adds significant 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?
The description clearly states the tool's purpose: 'Run a Haystack component with the given parameters.' It explains execution and testing use case, and the name and description distinguish it from sibling tools which deal with pipelines, indices, etc., not component execution.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description says 'Use this to test components and see how they would work in your pipeline,' giving clear context. It does not explicitly state when not to use or mention alternatives, but given the unique nature of the tool among siblings, this is acceptable.
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?
With no annotations, the description provides key behavioral details: the original object is not modified, the result is stored as a new object, and it returns the new object ID and a preview. It could mention error conditions or performance, but the core behavior is well disclosed.
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 well-organized: a brief opening sentence followed by a parameter list. It front-loads the purpose. However, the parameter list is somewhat verbose with repeated line breaks, which could be tightened without losing clarity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (6 parameters, regex substitution) and the absence of an output schema, the description fully covers what the tool does, its parameters, return value (new ID and preview), and safety (non-destructive). No critical information is missing, and it aligns with sibling context.
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%, so the description compensates by explaining all six parameters: `object_id`, `pattern`, `replacement`, `path`, `count`, `case_sensitive`. It adds meaning like "Supports backreferences" for `replacement` and "Navigate to a nested string attribute" for `path`, exceeding the schema's minimal definitions.
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 "Find and replace text in a string stored in the object store using regex," specifying the verb (find and replace), resource (string in object store), and method (regex). It distinguishes from siblings like `grep_object_store` (search) and `get_from_object_store` (retrieve).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explains the tool's operation (like `sed s/pattern/replacement/`) and that it creates a new object without modifying the original. While it implies usage for regex substitution, it does not explicitly state when to use this tool versus alternatives or provide exclusion criteria.
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?
With no annotations, the description must disclose behavior fully. It explains JSON/YAML parsing, re-serialization, the default store behavior, return types (preview vs. full result), and error messages. It does not explicitly state read-only nature but implies it by storing new objects. No contradictions with 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.
Conciseness5/5
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.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and 0% schema coverage, the description covers purpose, parameters, return values, and behavior with JSON/YAML. It mentions error conditions but lacks details on performance or size limits. Overall complete for a data query/transform tool.
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%, so the description compensates fully. It provides :param explanations for all four parameters: object_id (format with @obj_001), filter (jq expressions), path (optional nested attribute), and store (default True vs. inline). This adds crucial meaning beyond schema 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 the tool's purpose: querying or transforming structured data using a jq filter. It specifies the action (query/transform), resource (object store data), and method (jq filter). It differentiates from siblings like grep_object_store (text search) and sed_object_store (text substitution) by focusing on structured data transformation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear usage context: 'filter, map, select, or rewrite nested data without pulling the whole object into context.' It includes examples and explains the default behavior. However, it does not explicitly state when not to use or mention alternatives beyond implicit differentiation from siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Discloses immutability, version history, draft finalization, output storage, and object ID usage. No annotations, so description carries full burden and meets it thoroughly.

It covers the tool's role in the broader workflow and directs users to related tools when needed.
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 coverage is 0% (no descriptions in properties), but the description fully explains both parameters. pipeline_name is simply 'Name of the pipeline,' and query_id is given a detailed definition with instructions to obtain it from the query_id/search_history_id field of list_pipeline_traces or list_pipeline_search_history responses.
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 opens with a specific verb and resource: 'Retrieves the Haystack pipeline run trace including all spans for a single search history record.' It clearly differentiates from sibling tools by focusing on the full trace for a single query, and mentions alternatives for other granularities.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly states when to use ('Use this to deep-dive into a specific query run') and how to obtain required identifiers ('obtainable from list_pipeline_traces or list_pipeline_search_history'). It also provides concrete alternatives: 'For a targeted look at one span... use get_pipeline_trace_span_tags; for the logs, use get_pipeline_trace_logs.'
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?
With no annotations provided, the description carries the full burden. It discloses the return structure (logger, level, message, timestamp, extra fields), the exclusion of errors outside the pipeline, and the automatic storing of output with an object ID for reference. It does not mention pagination or auth, but provides substantial behavioral context beyond a simple read-only claim.
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?

This fully compensates for the schema coverage 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 first sentence states a specific action and scope: 'Runs a pipeline configuration in debug mode: pin a breakpoint, resume a snapshot, or trace a full run.' It also explicitly distinguishes from saved pipelines ('directly (not a saved pipeline by name)'), which separates it from siblings like run_component or deploy_pipeline.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description defines three mutually exclusive usage modes and tells users to pass YAML from get_pipeline_version/create_pipeline_version or a local draft. It provides concrete when-to-use guidance for dry_run ('Required for indexing pipelines... harmless for query pipelines') and warns to set it on resume too. However, it does not explicitly name alternative tools, so it stops short of full explicit exclusion guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full responsibility.
