Server Quality Checklist

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

Latest release: v0.2.2
Disambiguation2/5
Many tools overlap in purpose, especially legacy and modern versions (e.g., navigate_to_url vs navigate_and_scrape, take_screenshot vs interact_with_page). Multiple cleanup, orchestration, and browser session management tools have ambiguous boundaries, increasing the risk of misselection.
Naming Consistency2/5
Naming conventions are inconsistent: mix of snake_case and verb_noun (e.g., easy_replace, spawn_agent), deprecated tools mixed with current ones, and varied verb choices (list/get/find, create/delete/remove). No clear pattern is enforced.
Tool Count2/5
70 tools is excessive, especially with many legacy duplicates that should have been removed. The scope is broad but could be consolidated into fewer, more focused tools. The count is far beyond the typical well-scoped range.
Completeness3/5
The server covers many domains but lacks full CRUD in some areas (e.g., knowledge graph missing delete/update for relationships and memories). Legacy tools indicate dead ends, and while core workflows exist, notable gaps remain.
Average 3.2/5 across 70 of 70 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

Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, and the description lacks any behavioral context such as side effects, persistence, or permission requirements. It simply says to create a room without explaining what that entails.
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 single-sentence description is front-loaded and non-redundant, but it is too brief to be adequately informative. It could be expanded with key details without becoming verbose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness1/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity (4 parameters, no output schema, no annotations, and many siblings), the description is severely incomplete. It does not explain the concept of a 'delayed room', how coordination works, or what happens after creation.
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 coverage is 100% with detailed descriptions for all 4 parameters. The tool description adds no additional meaning beyond what the schema already provides, resulting in a baseline score.
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?
Description states verb 'Create' and resource 'delayed room' with purpose 'coordination', but it is vague about what 'delayed' means and does not clearly differentiate from other room-related siblings like close_room or join_room.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs alternatives like other room operations. The phrase 'when agents realize they need it' is not specific enough to inform decision-making.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It does not disclose that the tool is read-only, supports pagination, or any behavioral traits like rate limits or performance characteristics.
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 only one sentence, which is concise but lacks substance. It does not earn its place because it adds minimal value beyond the tool name. Could be improved without increasing length.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness1/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity (7 optional parameters, no output schema, many sibling tools), the description is severely incomplete. It omits filtering capabilities, pagination, and return format, leaving the agent underinformed.
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?
The input schema has 7 parameters with 0% description coverage, yet the description adds no information about parameter meanings, usage, or constraints. The enum and default values are not explained.
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 lists execution plans and mentions a context (discovery and monitoring). However, it does not differentiate from sister tools like 'get_execution_plan' or specify that it returns multiple plans.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives (e.g., 'get_execution_plan' for a single plan) or any preconditions. The agent is left to infer usage from the name alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description bears full burden for behavioral disclosure. It only implies analysis and suggestion but does not reveal side effects, required permissions, computational cost, return behavior, or any other operational details.
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 extremely short (one sentence) but lacks detail. It is concise, but at the expense of completeness; every sentence should earn its place, and this one does not provide sufficient information.
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 and no annotations, the description should compensate with richer context. It fails to explain what coordination patterns are, what format suggestions take, or any prerequisites, leaving significant gaps for an AI 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?
Schema description coverage is 100% for the single parameter 'repositoryPath', which is fully described. The tool description adds no extra semantic context beyond what the schema provides, resulting in baseline score.
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?
Description states 'analyze coordination patterns and suggest improvements', which is a verb-resource pair but lacks specificity. It doesn't clarify what constitutes coordination patterns or how improvements are suggested, making it vague compared to sibling tools like 'analyze_dom_structure' or 'analyze_file_symbols'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives. The description does not mention contexts, prerequisites, or exclusions, leaving the agent to infer its applicability from the name alone.
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 present, so the description carries the full burden. It only states 'Wait for messages' without explaining the blocking nature, timeout behavior, or what happens if the room doesn't exist or if no messages are received.
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 extremely brief (4 words) but under-specified for the complexity of the tool. It fails to provide necessary context, making it more incomplete than concise.
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 the three parameters and no output schema, the description should explain the return value (likely a list of messages), blocking semantics, and timeout consequences. It lacks these details, making it incomplete for an agent to use reliably.
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 schema already provides detailed descriptions for all three parameters (roomName, timeout, sinceTimestamp), achieving 100% coverage. The description adds no additional semantic value beyond what the schema offers, earning baseline score.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action (wait) and the resource (messages in a room). However, it does not differentiate from sibling tools like list_room_messages or send_message, which reduces clarity on when to use this specific tool.
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 (e.g., list_room_messages for non-blocking retrieval, send_message for sending). No when-not-to-use or prerequisite context is given.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description should disclose behavioral traits. It only states the high-level purpose without mentioning caching, .claudeignore respect, or output format. The schema description adds some context, but the tool's description itself is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise at one sentence. While it is not wasteful, it may be too brief for a tool with multiple parameters and behavioral traits, risking under-specification.
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 the complexity (5 parameters, no annotations, no output schema), the description is incomplete. It does not explain the output, side effects (caching, file creation), or how it differs from sibling tools like 'generate_project_summary'.
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 coverage is 100%, so the baseline is 3. The description does not add parameter semantics beyond what the input schema already provides, resulting in no extra value.
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 analyzes project structure and generates a comprehensive overview, matching the name. However, it does not differentiate from siblings like 'generate_project_summary' or 'get_project_overview', which could cause confusion.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives. The description lacks any when-to-use, when-not-to-use, or contextual best practices.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description bears full responsibility for disclosing behavior. It does not mention that the tool is destructive, what 'stale' means, notification behavior, or whether the operation is reversible. This is insufficient for a cleanup tool.
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 short sentence, which is concise. However, it is too vague and does not convey necessary details; it could be more informative without increasing length significantly.
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 and no annotations, the description should provide more context about prerequisites, side effects, and result format. It lacks details on what happens after cleanup, making it incomplete for safe usage.
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 100%, so the baseline is 3. The description adds little beyond the schema, only hinting at 'enhanced options' and 'optional room cleanup' which map to parameters but add no new meaning.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Clean up stale agents') and mentions 'enhanced options and optional room cleanup', specifying the resource and some features. However, it does not differentiate from sibling tools like 'cleanup_stale_rooms' or 'run_comprehensive_cleanup', which could cause confusion.
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. With many sibling cleanup tools, the lack of usage context makes it difficult for an agent to decide which to invoke.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits. It states 'clean up' but does not specify whether this involves deletion, archiving, or other actions. The presence of a dryRun parameter suggests potential destructiveness, but this is not articulated.
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 concise sentence, but it is too brief to be maximally useful. It could benefit from more detail while remaining concise.
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 the complexity of 6 parameters and no output schema or annotations, the description fails to provide sufficient context about return values, side effects, or prerequisites. For example, it does not indicate what the tool returns (e.g., list of cleaned rooms) or how the dryRun mode works.
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?
All 6 parameters have descriptions in the input schema, providing full coverage. The description adds no additional meaning beyond the schema, so it's adequate but not improved.
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 identifies the verb 'clean up' and resource 'stale rooms', and mentions criteria. However, it is somewhat generic and does not differentiate from other cleanup tools like 'cleanup_stale_agents' or 'run_comprehensive_cleanup'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives. There are many sibling cleanup tools, but the description does not specify when to choose this one over others like 'cleanup_orphaned_projects' or 'run_comprehensive_cleanup'.
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 disclose behavioral traits. It lists what the return includes (project structure, file counts, etc.) but omits performance, side effects, or whether the project must already be analyzed. This is 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.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that conveys the core purpose efficiently. It could be broken into structured bullet points, but it is not overly verbose.
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?
With no output schema, the description should thoroughly explain the return value. While it lists included items, it lacks depth (e.g., data types, format). Given the complexity and many sibling tools, the description is incomplete.
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 coverage is 100% for the single parameter projectPath. The description adds return value context beyond the schema but does not enhance parameter meaning significantly. Baseline 3 is appropriate.
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 description states 'Get comprehensive project overview from TreeSummary analysis', which is a specific verb and resource, but 'TreeSummary analysis' is ambiguous and not explained. Among siblings like analyze_project_structure and generate_project_summary, it lacks differentiation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives such as generate_project_summary or analyze_project_structure. There is no mention of prerequisites or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It mentions 'real-time updates' and 'EventBus' but does not disclose resource consumption, potential side effects, or automatic stopping behavior (implied by maxDuration in schema). The lack of detail on what happens during and after monitoring reduces transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence, making it brief and front-loaded. However, it is under-informative for a tool with 8 parameters and no other documentation. It earns its place but fails to deliver necessary detail, sacrificing substance for brevity.
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 8 parameters and no output schema or annotations, the description is insufficient. It does not explain what the monitoring output looks like, how to stop monitoring, or how parameters like monitoringMode and detailLevel affect results. The tool is reasonably complex, but the description leaves significant gaps.
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 100%, so the baseline is 3. The description repeats only the term 'real-time updates' and adds no meaningful explanation of parameters beyond what the schema provides. It does not summarize parameter interplay or usage patterns, offering minimal added value.
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 monitors agents with real-time updates via EventBus. The verb 'monitor' and the context of agents are specific, but it lacks differentiation from sibling tools like 'list_agents' which also involve agent observation. The schema provides additional detail via enums, but the description itself is somewhat generic.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives such as 'list_agents' for snapshots or 'broadcast_message_to_agents' for communication. There are no prerequisites or scenarios mentioned, leaving the agent to infer usage context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. 'Update' implies mutation, but the parameter description says 'scans and extracts' which suggests read-only analysis. This contradiction is not resolved, and no side effects or requirements are disclosed.
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?
One sentence is concise but omits critical behavioral context. It is appropriately short but could front-load more information about side effects or return values.
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?
With one optional parameter and no output schema, the description is too sparse. It does not explain what happens on invocation, what the return value is, or how to distinguish from similar analysis tools.
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 100% for the single parameter, so baseline is 3. Description adds 'Update project metadata' but does not add new meaning beyond the schema's parameter description.
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?
Description states verb 'Update' and resource 'project metadata in the TreeSummary system', clearly indicating the action and scope. However, it does not differentiate from siblings like 'analyze_project_structure' or 'generate_project_summary', which may overlap.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives. Given the many sibling tools, the agent has no context to decide when to choose this over related analysis 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?
With no annotations provided, the description must fully disclose behavioral traits, but it only states that the tool analyzes stored data. It does not confirm read-only behavior, disclose side effects, or address permissions, leaving significant ambiguity.
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 sentences, efficiently conveying the core purpose. However, it could be more structured by explicitly listing what it identifies, but there is no wasted text.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the absence of an output schema and annotations, the description is adequate but incomplete. It does not explain return values, prerequisites (e.g., that the page must already be stored), or how the AI guidance works, leaving gaps for a complex tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
All four parameters are described in the input schema (100% coverage), so the description adds minimal extra semantics. The description's mention of 'goal-oriented patterns' provides context but does not clarify parameter usage beyond what the schema already offers.
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 analyzes stored DOM JSON to identify interactive elements, content areas, and navigation patterns. It specifies the action (analyze) and resource (DOM structure) but does not explicitly differentiate from sibling tools like search_dom_elements or navigate_dom_path, leading to 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 offers no guidance on when to use this tool versus alternatives, nor does it mention prerequisites or exclusions. It only implies usage for DOM analysis, which is insufficient for an agent to make informed decisions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It mentions AI-powered analysis but fails to disclose whether it captures a new screenshot or uses an existing one, what the output format is, or any side effects. Minimal behavioral context.
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?
Two sentences, front-loaded with purpose, no redundant words. Efficient and clear.
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, the description should clarify return value. It does not. Also lacks context on whether a screenshot must be pre-captured or is taken automatically. Incomplete for effective use.
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 coverage is 100%, so baseline is 3. The description adds 'focus on specific regions' aligning with focus_region, but no new meaning beyond schema descriptions. No added value for page_id or analysis_prompt.
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 performs AI-powered analysis of page screenshots using custom prompts, and can focus on regions. This distinguishes it from sibling tools like 'take_screenshot' (capture) and 'analyze_dom_structure' (DOM analysis), though 'contextual insights' is vague.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives, such as other analysis tools. The description does not mention prerequisites, such as whether a screenshot must already exist, or when to prefer this over DOM-based analysis.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It only states it cancels active or pending jobs but does not disclose whether cancellation is irreversible, what happens to partial data, or any side effects. Minimal behavioral detail.
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 extremely concise with a single clear sentence. It is well-structured and front-loaded. While little information is present, it is efficiently conveyed.
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 cancellation tool with one parameter and no output schema, the description is moderately complete. It lacks details on expected outcomes or error states, but covers the basic action.
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 input schema has 100% coverage with a detailed description for job_id, explaining its source. The main description adds no further parameter info, but the schema already suffices. Baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Cancel' and the resource 'scraping job' with scope 'active or pending'. It effectively conveys the tool's purpose, though it does not differentiate from sibling tools like stopping via other means.
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 is provided on when to use this tool versus alternatives (e.g., waiting for completion or checking status with get_scraping_status). The description lacks contextual cues for appropriate usage.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations present, the description carries the full burden. It does not disclose side effects (e.g., whether creation triggers assignment immediately), permissions needed, or any constraints like rate limits. The term 'enhanced capabilities' is ambiguous.
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 a single concise sentence, front-loading the purpose. However, it could be more structured by breaking into a brief usage summary and a note on behavior.
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 the tool has 6 parameters including a nested object and no output schema, the description should at least hint at return values (e.g., task ID) or typical usage flow. It lacks completeness for a moderately complex creation tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the base is 3. The description adds no extra meaning beyond the schema, missing an opportunity to explain relationships between parameters (e.g., how 'requirements' interacts with 'taskType') or provide usage 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 indicates the tool creates and assigns a task to agents, with a mention of 'enhanced capabilities' which is vague but does not obscure the core purpose. It distinguishes from siblings like 'create_execution_plan' which focuses on plans rather than tasks.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives like 'spawn_agent' or 'create_execution_plan'. The description lacks any contextual hints about appropriate scenarios or prerequisites.
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 adds context about whitespace normalization and indentation preservation beyond annotations (none provided). It implies file modification but doesn't explicitly state side effects, error handling, or permission requirements.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is very short (one sentence) but lacks structure or front-loading of critical details. It could be more informative without being verbose.
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?
No output schema is provided, and the description does not explain the return value or behavior (e.g., success/failure, modified file contents). The tool has 5 parameters, but the high-level description does not cover enough context for an agent to use it fully.
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 100%, so the schema already documents all parameters. The top-level description adds no additional meaning beyond the schema's parameter descriptions.
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 'Fuzzy string replacement in files with smart matching', specifying the verb (replace) and resource (files). It distinguishes itself from siblings by focusing on fuzzy replacement, but does not explicitly contrast with similar file manipulation tools.
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. It does not mention prerequisites, conditions for use, or when to prefer sibling tools like find_files or list_files.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden but only states 'execute an objective'. It does not disclose whether execution is asynchronous, what side effects occur, or any required permissions. Behavioral traits like progress monitoring are implied only through parameters.
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?
A single sentence with no fluff, but it omits important context. It earns its place but could be more informative without being verbose.
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 5 parameters, no output schema, and no annotations, the description is too minimal. It fails to explain the execution process, return status, or the role of parameters like 'executeImmediately' and 'monitoring'. Sibling tools like 'create_execution_plan' suggest a workflow, but this description lacks that context.
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 coverage is 100% with descriptions for all 5 parameters. The description adds no value beyond what the schema already provides (e.g., 'planningId' is self-explanatory). Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Execute an objective using a pre-created execution plan', distinguishing it from sibling tools like create_execution_plan or get_execution_plan. However, it could be more specific about what 'execute' entails (e.g., sequential or parallel task execution).
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?

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full behavioral burden. It mentions pattern matching and content preview but does not disclose return format, performance implications, or safety characteristics. The description adds minimal transparency beyond the schema.
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 a single sentence, which is concise and front-loaded with the core purpose. It could benefit from slight expansion but avoids unnecessary verbosity.
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 the absence of an output schema, the description should explain return values. It does not. It also fails to distinguish from sibling tools like 'list_files'. The description is adequate but incomplete for a tool with 4 parameters and no structured metadata.
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 coverage is 100%, so the description adds limited value. It references pattern and content, but does not elaborate on parameter nuances beyond what the schema already provides. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it searches files by pattern with optional content matching. It is a specific verb+resource, but lacks explicit differentiation from the sibling tool 'list_files', which likely lists all files without filtering.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives like 'list_files' or other search tools. Context signals show many sibling tools, but the description offers no usage conditions or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavior. It only states 'Generate AI-optimized project overview and analysis' without mentioning that it reads files, modifies nothing, or requires local file access. Behavioral details are insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single efficient sentence. It is front-loaded and to the point, though it lacks detail.

Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives. The description lacks context for appropriate use cases or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must fully disclose behavior. 'Join' implies a state change (agent becomes a member), but it does not specify if joining is persistent, if rooms must exist, or what side effects occur (e.g., receiving messages). Lacks details on error handling or security.
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 a single sentence, very concise. It could be slightly expanded to include more context, but it is not verbose. Every word is functional.
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 the simplicity of the tool (no output schema, few parameters), the description is minimal but incomplete. It does not mention that the room must exist, what happens if the agent name is taken, or how to leave the room afterwards. More context would help an agent use it correctly.
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 coverage is 100% with clear descriptions for both roomName and agentName. The description adds no additional meaning beyond the schema. Baseline 3 is appropriate.

Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Join communication room for coordination' clearly states the action (join) and the resource (communication room). It distinguishes from siblings like close_room (opposite) and list_rooms (listing). However, it does not elaborate on what 'coordination' entails, leaving some ambiguity.
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 like send_message or broadcast_message_to_agents. The context of joining a room before communicating is implied, but the description does not state prerequisites or when to choose this 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, so description carries full burden. It fails to disclose pagination behavior, scope via repositoryPath, or side effects. Only states 'list of active agents,' which is incomplete.
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?

Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has 4 parameters, no output schema, and many siblings, the description is too sparse. It lacks details on return format, pagination, or differentiation from similar tools.
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 coverage is 100%, providing full parameter descriptions. The description adds no additional meaning beyond the schema, so baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description 'Get list of active agents' clearly states the action and resource, but slightly misleads by implying only active agents, while the schema allows filtering by any status. Distinguishes from siblings like monitor_agents broadly.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives like monitor_agents or when to filter vs list all. The description offers no usage context or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits, but it only mentions queuing and selectors. It lacks information on side effects (e.g., whether it modifies the website), authentication needs, rate limits, or what happens to the scraped data. This is insufficient for a complex scraping tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is brief and front-loaded, but for a tool with many parameters, it could benefit from slightly more structure (e.g., grouping filtering options). It earns its place but is a bit too terse.
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 the complexity of 26 parameters and no output schema, the description is too minimal. It doesn't explain return values, error handling, or background behavior. The schema descriptions help, but the tool description itself lacks context for an agent to use it effectively.
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?
All 26 parameters have full descriptions in the input schema, so the description adds minimal value. It mentions 'plain string selectors' but the schema already covers that. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool scrapes documentation using sub-agents, but it does not distinguish itself from sibling scraping tools like 'scrape_content' or 'navigate_and_scrape', which would be necessary for an agent to choose correctly.

Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity (8 parameters, no output schema) and many sibling tools, the description is insufficient. It lacks explanation of return value, agent lifecycle, coordination room usage, and how spawned agents interact with other tools.
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 coverage is 100%, so the baseline is 3. The description adds no additional meaning beyond the already detailed parameter descriptions in the input schema. For example, it doesn't clarify how agentType affects behavior beyond the 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?

Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives. The description says 'Use this to capture important information' but lacks exclusions or context about when not to use it. No alternative tools are mentioned.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It only states the action without disclosing side effects, such as resource cleanup, impact on related tasks, or whether agents can be restarted. The parameter description adds some detail (graceful shutdown), but the tool-level description lacks this transparency.
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?

For a delete operation with no output schema or annotations, the description should at least mention that the action is permanent or irreversible. It lacks completeness for safe invocation.
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?
The input schema has 0% description coverage, and the tool description does not add any meaning to the 'planId' parameter beyond its name and type. The agent receives no guidance on what constitutes a valid planId or how to obtain it.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action (delete) and the resource (execution plan) with the identifier (by ID), effectively distinguishing it from sibling tools like create, get, list, and update.

Given the tool has 10 parameters, no output schema, and no annotations, the description is too brief. It fails to explain key aspects like valid progress types, broadcast behavior, and when optional fields like taskId are required.
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 100%, so baseline is 3. The description does not add any parameter-specific meaning beyond what the schema already provides. It is acceptable but does not enhance understanding.
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: reporting progress updates for agent tasks and status changes. It uses a specific verb ('report') and resource ('progress updates for agent tasks and status changes'), and is distinct from sibling tools like create_task or list_agents, which have different functions.
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. It does not mention prerequisites, context, or when not to use it, leaving the agent to infer usage from the tool name alone.
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 mentions 'auto-resume functionality', which is a key behavioral trait. However, it does not disclose other behaviors such as whether the operation is safe (non-destructive), permissions required, or side effects beyond resume.
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 a single concise sentence, front-loaded with the core action. However, it is so brief that it sacrifices completeness, missing important context that could be added with minimal extra words.
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?
For a tool with 6 parameters, no output schema, and no annotations, the description is inadequate. It does not explain the return value, the role of repositoryPath, or the significance of priority/messageType. Siblings like send_message and list_agents provide context not leveraged here.
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 100%, so baseline is 3. The description adds no additional meaning beyond what the schema already provides; the auto-resume mention is already covered in the autoResume parameter description.
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 broadcasts a message to multiple agents, which is a specific verb+resource. It implies broadcasting to many agents, distinguishing it from send_message (likely one-to-one). However, it does not explicitly differentiate from siblings like send_message or list_agents.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives such as send_message. There is no mention of prerequisites, exclusions, or context for using broadcast over other communication 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, so the description carries the full burden. It states 'Clean up orphaned or unused project directories' but does not disclose that the tool may delete directories, what permissions are required, or whether changes are reversible. The schema notes that dry_run defaults to true for safety, but this is not mentioned in the description itself.
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 a single concise sentence. While it could be more informative, it is efficiently worded and front-loads the main action without unnecessary fluff.
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 the tool has 3 parameters and no output schema, the description is incomplete. It does not mention the criteria for orphaned projects (package.json or .git), the safety default of dry_run, or the possible outcome (actual deletion vs. listing). The input schema's description covers these details, but the description itself lacks completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% (each parameter has a description). The description adds no additional meaning beyond the schema; for example, the dry_run parameter's purpose is already clear from the schema. The overall schema description gives some context about project detection criteria, but the description does not enrich parameter understanding.
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 'Clean up orphaned or unused project directories' clearly states the verb (clean up) and resource (orphaned project directories). It is specific enough to convey the tool's core function, though it does not explicitly differentiate from sibling cleanup tools like 'cleanup_stale_agents' or 'cleanup_stale_rooms'.
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 does not provide explicit guidance on when to use this tool versus alternatives (e.g., 'run_comprehensive_cleanup'). The input schema description implies usage by mentioning that it looks for directories with package.json or .git, but no when-to-use or when-not-to-use information is given.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden but only says 'continue' without disclosing behavioral traits such as state changes, error handling, or required permissions. The agent cannot infer side effects from the description alone.
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 a single sentence that is front-loaded with the main purpose. It is concise, though it could include a brief usage note without becoming verbose.
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 description is too brief for a tool with 5 parameters, nested objects, and no output schema. It does not explain the return value, error conditions, or how the session continuation works in practice. The schema covers parameters, but the overall description lacks completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5

Schema description coverage is 100%, so parameters are fully documented in the schema. The description does not add additional semantic context beyond what the schema provides, meeting the baseline.
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 'continue an agent session' and specifies the mechanism 'using stored conversation session ID with additional instructions'. It distinguishes the tool from siblings like spawn_agent or terminate_agent.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives (e.g., when to start a new session vs. continue). No mention of prerequisites or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It only states the creation action without disclosing behavioral traits like idempotency, side effects, permissions, or error conditions. The schema provides parameter details but no behavioral context.
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 a single, direct sentence: 'Create a relationship between two entities in the knowledge graph'. It is concise and avoids unnecessary words, though it could incorporate more context without becoming verbose.
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 the tool's complexity (9 parameters, no output schema), the description is too brief. It lacks information about return values, typical usage, or post-creation effects. The schema description helps but does not compensate for missing completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the baseline is 3. Each parameter has a clear description in the schema, and the tool description adds 'directional' context, but overall the description does not significantly enhance understanding beyond what the schema already provides.
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 'Create a relationship between two entities in the knowledge graph' clearly states the action (create) and resource (relationship in knowledge graph). The schema description adds further detail, and the tool is easily distinguishable from siblings like find_related_entities.
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 is provided on when to use this tool versus alternatives. The schema description implies its use for establishing connections, but there is no mention of prerequisites, exclusions, or comparisons with sibling 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?
With no annotations, the description must disclose behavioral traits. It does not mention irreversibility, permissions, cascading effects, or error handling. For a destructive tool, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence with no unnecessary words, making it concise. However, it lacks structure (e.g., bullet points) that could aid readability.
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 annotations, no output schema, and a single parameter, the description is too thin. It omits important context like return values, idempotency, and side effects, leaving the agent underinformed.
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 coverage is 100% for the single parameter, so the schema already provides meaning. The description adds no extra context beyond what is in the schema parameter description.
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 'Delete specific pages by their IDs' clearly states the action (delete), the resource (pages), and the method (by IDs). It differentiates from sibling tools like delete_pages_by_pattern and delete_all_website_pages.
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, no prerequisites, and no exclusions. It is a single sentence without usage context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description bears full responsibility for behavioral disclosure. It only says 'retrieve' without indicating whether it's read-only, requires permissions, or has any side effects. The absence of any behavioral context reduces transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, concise sentence with no extraneous information. However, it lacks structural elements like bullet points or formatting that could improve scanability.
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?
For a retrieval tool with no output schema and no annotations, the description is minimal. It does not explain what the execution plan contains or how to interpret the response, leaving the agent with insufficient context for reliable invocation.
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 input schema already describes the single parameter with 100% coverage: 'ID of the planning session to retrieve'. The description adds no additional meaning beyond the schema, meeting the baseline for high schema coverage.

Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action (clean up), the resource (stale analysis files), and the condition (older than specified days). It effectively distinguishes from sibling cleanup tools like cleanup_orphaned_projects and cleanup_stale_agents by targeting analysis files specifically.
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. It does not mention prerequisites, scenarios where it is appropriate, or when to avoid using it. Given the many sibling cleanup tools, this lack of context forces the agent to rely on tool names alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full behavioral disclosure. It only states 'force unlock', which implies a mutation, but does not detail side effects, permissions, or what happens internally. This is insufficient for an agent to understand all behavioral traits.

Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Force unlock a stuck scraping job' with a verb and resource. The name is descriptive and the input schema further clarifies it's for debugging and recovery. However, it doesn't explicitly distinguish from sibling tools like cancel_scrape_job or force_unlock_stuck_jobs, though the singular job_id implies uniqueness.
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 says 'useful for debugging and recovery' and the input schema adds 'when jobs become unresponsive', providing implicit usage context. However, it does not mention when not to use it or alternative tools like cancel_scrape_job, so guidance is minimal.
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 indicates a mutation ('Update') without disclosing side effects, atomicity, partial update behavior, or permission requirements, leaving significant gaps.

Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no annotations or output schema, the description is insufficiently complete. It does not explain the output format, error conditions, or language support, leaving important context lacking for effective tool use.
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 coverage is 100% with descriptions for both parameters. The description adds no additional meaning beyond the schema, meeting baseline for coverage. Output format is not described, but schema lacks output 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 action (extract and analyze), resource (symbols from code files), and provides examples (functions, classes). It distinguishes from sibling tools like analyze_project_structure or analyze_dom_structure, which handle different scopes.
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 does not explicitly state when to use this tool versus alternatives. While sibling tool names imply different contexts, no explicit guidance is provided within the description.
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 implies read-only behavior via 'get'. However, it doesn't disclose whether permissions are needed, side effects, or if the configuration is subject to caching or staleness. The transparency is adequate but minimal.
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?
Single sentence, clear and to the point. No redundant words.
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 and no annotations, the description should provide more context about what the configuration contains (e.g., timeouts, retention policies). It doesn't specify return format or behavior, leaving the agent uncertain.
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 and schema description coverage is 100%. The description adds nothing beyond the schema, but since no parameters exist, baseline 3 is appropriate. The lack of needed parameter info doesn't detract.
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 cleanup configuration for agents and rooms. It distinguishes from sibling tools that perform cleanup actions (e.g., cleanup_stale_agents) by indicating it's a 'get' operation, but it doesn't explicitly contrast with other configuration-like 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?
No guidance on when to use this tool versus alternatives like run_comprehensive_cleanup or cleanup_stale_agents. The description does not mention prerequisites, context, 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.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided. The description mentions 'worker runs automatically' hinting at background behavior but lacks details on read-only nature, rate limits, or what constitutes 'active and recent'. The schema description adds some context but the tool description itself is minimal.
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 a single sentence with verb and resource, no redundant words. It is front-loaded and efficient, though slightly sparse.
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?
No output schema is provided, and the description does not explain what the response contains (e.g., fields like active_jobs, history). For a monitoring tool, this omission leaves the agent underinformed about expected results.
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?
Input schema has 2 parameters with descriptions, and schema description coverage is 100%. The tool description does not add additional meaning beyond the schema, so baseline score of 3 applies.
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 'Get status of active and recent scraping jobs', specifying the verb (get) and resource (status of scraping jobs). It distinguishes from siblings like 'cancel_scrape_job' (different action) and 'scrape_content' (different purpose).
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 for monitoring scraping progress, but it does not explicitly state when to use this tool versus alternatives like 'get_job_status' (if existed) or 'list_jobs'. No guidance on exclusions or prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It only lists actions and does not disclose behavioral traits such as failure handling, session prerequisites, or side effects. The schema includes some behavioral details (e.g., sequence stops on first failure), but the description does not repeat or add to them.
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 a single sentence listing actions, which is concise and front-loaded. It could be slightly more informative (e.g., noting session requirement or execution order) but remains efficient without unnecessary verbosity.
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 the complexity (array of actions with many subproperties) and no output schema, the description is too brief. It does not explain return values, execution flow, or error behavior, leaving the agent with insufficient context to use the tool effectively despite the rich schema.
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 100%, so baseline is 3. The description adds no extra meaning beyond listing action types; parameter details are fully covered by 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 the tool performs multiple interactions (click, type, hover, select, screenshot, wait, scroll) on a page, distinguishing it from siblings like 'interact_with_element' (single action) and 'take_screenshot' (screenshot only).
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 does not explicitly state when to use this tool versus alternatives. The list of actions implies it is for sequences, but no guidance on prerequisites or exclusion cases is provided. Sibling names offer context, but the description lacks direct usage heuristics.
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?
The description provides minimal behavioral context beyond 'list'. No information about performance implications, authorization requirements, or what constitutes a 'configured documentation source'. The parameter description in the schema adds some context but the main description is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, concise sentence that conveys the core purpose without any extraneous words. It is front-loaded and efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description is complete for its stated purpose but omits details about the output format or what fields are returned for each source. Since no output schema exists, the description should clarify the return structure for better completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% for the single parameter 'include_stats', which is well-documented in the input schema. The tool description does not add further semantics, so a baseline of 3 is appropriate.
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 the specific verb 'List' and resource 'all configured documentation sources', clearly identifying the tool's action and scope. It distinguishes from sibling tools like 'scrape_documentation' or 'delete_all_website_pages' which perform different operations.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives. The description does not mention prerequisites, when listing is appropriate, or how it relates to other tools for managing documentation sources.
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?
Without annotations, the description minimally conveys a read-only list operation. It mentions filtering and pagination but omits side effects or safety guarantees. For a list tool, this is acceptable but not enriched.
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?
One sentence, 5 words – very concise and front-loaded. It conveys the essential purpose, though it could include a bit more context without losing efficiency.
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 description does not specify the return value format (e.g., list of room IDs, objects). It also lacks differentiation from similar list tools. Given no output schema, this leaves gaps for the 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?
Schema description coverage is 100%, so the baseline is 3. The tool description adds no new parameter information beyond what the schema already provides.

Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('list'), the resource ('communication rooms'), and key features ('filtering and pagination'). It effectively distinguishes from sibling tools like close_room or delete_room.
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 over alternatives (e.g., list_room_messages). The description does not mention prerequisites or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavioral traits. It only says 'manage' without stating that actions like 'close' and 'cleanup_idle' are destructive. The schema mentions protection for documentation sessions, but the description omits this crucial behavioral detail.
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 a single sentence that efficiently conveys the tool's scope. It is not overly verbose, though it could benefit from structured format (e.g., bullet points) for clarity.
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 the tool's complexity (4 parameters, nested object, multiple actions) and lack of output schema, the description is too minimal. It does not explain action outcomes, return values, or when to use specific actions, leaving the agent underinformed.
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?

Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description explicitly states the tool's purpose: managing browser sessions with actions like list, close, cleanup idle, and get status. It clearly distinguishes from siblings such as 'list_browser_sessions' and 'close_browser_session' by offering a consolidated management interface.
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 lists actions but does not explicitly guide when to use this tool versus sibling tools. It implies usage for multi-action management (e.g., bulk cleanup) but lacks direct comparisons or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Implies usage before spawning agents, but does not explicitly say when to use this tool vs alternatives. Lack of explicit when-not or alternative explanations.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must convey behavioral traits. It mentions deletion but does not disclose that the operation is destructive, irreversible, or that a dry run should be performed first. The schema includes a dry_run parameter with safety notes, but the main description omits this critical warning.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single clear sentence with no unnecessary words. It is front-loaded with the core action and use case.

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 exist, so the description must disclose behavioral traits. It mentions 'smart ignore patterns' but does not explain what that means (e.g., .gitignore-like rules? any special behavior?). No details about performance, side effects, or access 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?
Two concise sentences that get to the point. However, 'smart ignore patterns' is somewhat vague and could be more precise. Overall, tightly written with no wasted words.
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 tool with 4 parameters and no output schema or annotations, the description is somewhat complete but lacks details on return format, pattern syntax, and behavior when patterns are combined. It's sufficient for basic understanding but not fully self-contained.
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 100% and the input schema provides descriptive parameter names and defaults. The tool description adds only the phrase 'smart ignore patterns' which adds minimal value beyond the schema's own descriptions.
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 lists files in a directory, with a specific verb ('List') and resource ('files in a directory'). It adds 'smart ignore patterns' to distinguish from simpler list tools. Sibling tools include 'find_files' and others, so this description sets it apart.
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 for directory exploration with pattern filtering, but provides no explicit guidance on when to use this vs. sibling tools like 'find_files' or when not to use. No alternatives or exclusions mentioned.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description is the sole source of behavioral insight. It only mentions navigation without disclosing side effects, authentication needs, or irreversible actions. This is insufficient for an agent to fully understand the tool's impact.
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 a single sentence that conveys the core purpose and a critical usage warning. It is concise without unnecessary information, earning its place through clarity and brevity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the legacy status and the clear alternative, the description is adequate for an agent to decide not to use it. However, it omits any description of return values or what happens after navigation (e.g., page load state). For a complete understanding, more detail would be beneficial.
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 coverage is 100%, and the input schema already describes each parameter adequately (e.g., session_id, url, wait_until, timeout). The description does not add any new semantic meaning beyond what the schema provides, so it meets the baseline but adds no extra value.
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 action: navigating to a URL in an existing browser session. It also distinguishes itself from the sibling tool navigate_and_scrape by marking itself as legacy and recommending the alternative, which helps the agent understand its role.
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 advises to use navigate_and_scrape instead, providing clear guidance on when not to use this tool. However, it does not elaborate on specific scenarios where this tool might still be preferred (e.g., when you already have a session and want minimal overhead).
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must fully disclose behavioral traits. It mentions spawning an architect agent but does not clarify whether this is a read-only operation, what side effects occur (e.g., agent creation), or any required permissions. The cost-saving hint via foundationSessionId is only in the schema, not the description.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, short sentence that conveys the core functionality without extraneous words. It is front-loaded with the key action and resource ('spawn architect agent to coordinate').
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?
For a tool that spawns an architect agent for multi-agent coordination, the description lacks crucial context: what the tool returns, how the coordination is performed, and any lifecycle implications. No output schema exists, so the description should compensate, but it does not.
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 100%, so the baseline is 3. The description does not add additional meaning beyond the schema; it simply restates the tool's purpose. All parameters are well-documented in the schema, so no credit for replication.

The description implies use for multi-agent objectives but does not explicitly state when to use this tool vs alternatives such as orchestrate_objective_structured or spawn_agent. No exclusions or when-not-to-use guidance is provided.
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, leaving the description to carry the full burden. It mentions phases but does not disclose behavioral traits like what happens during cleanup, model selection criteria, or error handling. For a complex orchestration tool, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
A single, densely packed sentence that efficiently conveys the core function with zero waste. It is front-loaded and highly concise.
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 the tool's complexity (7 parameters, phased workflow, no output schema), the description is too brief. It does not explain how phases interact, the role of customPhaseConfig, or the impact of maxDuration, leaving agents without sufficient context for effective invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5

Single sentence, no unnecessary words. Highly concise and front-loaded with the core action and key qualifier (soft delete).
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Covers main behavior and key parameters. Lacks return value information or any post-condition guarantees (e.g., whether the room can be reopened). For a simple mutation tool, this is above baseline but could be more complete.
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 coverage is 100% with clear field descriptions. The description adds context by reiterating the soft delete nature, but does not provide significant additional 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?
Description clearly states it closes a communication room with soft delete behavior, distinguishing it from hard delete tools like delete_room or cleanup_stale_rooms. The precise verb 'close' and resource 'communication room' make the purpose unambiguous.
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 over alternatives (e.g., when to delete vs close, or when to terminate agents). 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.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It mentions auto-creating sessions but does not disclose side effects, error handling, or other behavioral traits like 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, front-loaded with the core action, and contains no redundant information. Every word adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the high parameter count, no output schema, and no annotations, the description is adequate but leaves gaps: it doesn't summarize return values, error scenarios, or contrast with sibling tools like 'scrape_content'.
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 coverage is 100%, so parameters are already well-documented. The description adds context about auto-creating sessions but doesn't significantly enhance parameter understanding 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 the tool navigates to a URL and optionally scrapes content, combining two operations. It distinguishes itself from sibling tools like 'navigate_to_url' and 'scrape_content' by offering a combined operation.
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 the tool is for one-step navigation and scraping, but lacks explicit guidance on when to use it versus the separate navigate/scrape siblings. No exclusion criteria or alternatives 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 clearly states the action (close a browser session), but lacks details on side effects, permissions, or cancellation of ongoing operations. No annotations are provided, so the description carries the full burden, which is only partially met.
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 short and front-loaded with '[LEGACY]', efficiently conveying purpose and deprecation. It earns its place, though it could be slightly more comprehensive without significant bloat.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (one parameter, no output schema, no nested objects), the description is adequate for a legacy tool with a clear alternative. However, it could be more complete by explaining the actual behavior of closing a browser session.
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?
The input schema has one required parameter 'session_id' with no description, and the tool's description does not provide any additional meaning. With 0% schema description coverage, the description should compensate but fails to do so.
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 that the tool closes a browser session, using a specific verb and resource. It also explicitly distinguishes itself from the sibling tool 'manage_browser_sessions' by recommending its use instead.

Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit guidance: 'Use manage_browser_sessions instead', indicating when not to use this tool and directing the agent to the preferred alternative.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full responsibility for behavioral disclosure. It only notes legacy status and suggests an alternative, but does not describe any behavioral traits such as side effects, error conditions, or limitations of the legacy tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise: a single sentence with a clear deprecation notice and alternative recommendation. No wasted words.
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?
As a legacy tool with a recommended replacement, the description provides minimal context. It does not explain return values or behavior, but the schema is detailed. Given the legacy status, it is adequate but not fully informative for an agent that might still need to use it.
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 input schema covers 100% of parameters with descriptions, so the baseline is 3. The tool description itself adds no additional parameter information, but the schema is sufficient.
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: 'Interact with a page element.' It immediately marks itself as '[LEGACY]' and directs users to a sibling tool, providing clear differentiation.
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 tells users to use 'interact_with_page instead,' providing a clear alternative and when-not-to-use guidance. It lacks specific when-to-use scenarios beyond legacy, but the recommendation is strong.
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; the description suggests a read-only search operation but does not explicitly state whether it mutates state, performance implications, or auth requirements. Adequate but not fully transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, each adding distinct value. First sentence states purpose, second mentions return value and subsequent use. No unnecessary words.
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 tool with nested search criteria and no output schema, the description is too brief. It lacks detail on how multiple criteria combine, what the returned 'paths' look like, or pagination behavior. Adequate but not complete given complexity.
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 coverage is 100% with all parameters described. The description restates that search is by type, content, keywords, or attributes, adding no new semantic value 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 the tool searches DOM elements by multiple criteria (type, content, keywords, attributes) and returns matching elements with paths. It is distinct from siblings like analyze_dom_structure or interact_with_element.
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 for finding elements before navigation, but does not specify when to use vs alternatives (e.g., analyze_dom_structure, interact_with_element). No exclusion or prerequisite mention.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden for behavioral disclosure. The description only states the action without explaining side effects (e.g., file saving, return behavior) or prerequisites beyond 'current page'. Important behavioral context is missing, such as the need for an existing browser session and what happens with parameters like return_for_ai.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise, consisting of a single sentence plus a legacy note. It front-loads the legacy flag and the alternative recommendation, making it efficient and actionable with zero wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has 6 parameters and no output schema, the description provides minimal context beyond the legacy warning. While the schema covers parameters, the description does not summarize the overall workflow or mention relationships between parameters (e.g., filepath vs return_for_ai). It is adequate for a simple tool but lacks completeness for nuanced use.
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 input schema has 100% description coverage for all 6 parameters, so the description does not need to add much. The description provides no additional semantic insight beyond what the schema already offers, resulting in a baseline score of 3.
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 captures a screenshot of the current page, using the verb 'take a screenshot' and specifying the resource. It also distinguishes itself from siblings by marking the tool as LEGACY and directing to interact_with_page, making its purpose unambiguous.
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 tells the agent to use interact_with_page instead, providing an alternative tool. This gives clear guidance on when not to use this tool. However, it does not elaborate on scenarios where the legacy tool might still be necessary, but the alert to avoid it is strong.
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 conveys destructive behavior ('permanently delete') and scope (all messages), but omits permissions, irreversible nature, or effect on active rooms. The schema's forceDelete param adds some context.
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?
A single, concise sentence front-loading the action and scope. Every word is necessary and earned.
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 simple delete operation, the description covers the core effect. However, it does not mention error states or linked data impacts, though the schema covers parameters well.
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 coverage is 100% with parameter descriptions, so the description adds no additional meaning beyond what the schema already provides. Baseline of 3 is appropriate.

Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states a specific verb 'delete' and resource 'communication room', and distinguishes from siblings like close_room and cleanup_stale_rooms by emphasizing permanence and message removal.
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 for permanent room deletion but lacks explicit when-to-use or when-not-to-use guidance. The forceDelete parameter description gives some context, but no direct comparison to alternatives like close_room.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden. It discloses that the tool retrieves stored data (read-only behavior) but does not mention idempotency, required permissions, or what happens if the screenshot is missing. It is adequate but lacks full transparency.
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?
Two sentences, front-loaded with the core purpose. Every word contributes value. No fluff or 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 the low complexity (2 parameters, no output schema), the description covers the main functionality and output. However, it omits error handling (e.g., screenshot not found) and response structure details, which could be helpful for a complete understanding.
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 coverage is 100% with descriptions for both parameters. The description adds context about the return format ('file path or base64 encoded image data for AI visual analysis') but does not significantly enhance understanding beyond the schema. Baseline 3 is appropriate.
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 ('retrieve stored screenshot'), the resource ('a page'), and the output format ('file path or base64 encoded image data'). It distinguishes itself from sibling tools like 'take_screenshot' (captures new screenshot) and 'analyze_screenshot' (analyzes existing screenshot).
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 that the screenshot already exists (retrieve stored), but it does not explicitly state when to use this over alternatives like 'take_screenshot' for capturing new screenshots or 'analyze_screenshot' for analysis. No conditions or prerequisites are mentioned.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It merely states it scrapes content but does not disclose if it is read-only, destructive, or any side effects. The legacy label hints at deprecation but lacks behavioral details.
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 very concise (one line plus legacy note) and front-loaded with the legacy warning. It is appropriately sized for a deprecated tool, though it could include a bit more context for agents that might still use it.
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?
With no output schema and no annotations, the description is minimal. It provides the essential directive to use an alternative, but for agents that might still invoke it, it lacks completeness about behavior, return format, or prerequisites beyond the schema.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

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 100%, with detailed descriptions for all 11 parameters. The description adds high-level context (e.g., 'intelligent auto-close') but does not significantly enhance individual parameter semantics beyond what the schema already provides.
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 states 'Create a new browser session with intelligent auto-close and session management', which clearly indicates the verb and resource. It distinguishes from sibling tools like 'close_browser_session' and 'list_browser_sessions' by emphasizing creation and management features.
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 hints at usage contexts through the workflow_type parameter (documentation, automation, testing) and mentions special handling for documentation sessions. However, it does not explicitly state when to use this tool over alternatives or provide exclusions.
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 full burden. It discloses that the tool is legacy, which is a behavioral trait (deprecated). For a simple list operation, this is sufficient additional context beyond the name.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences long with zero wasted words. It is front-loaded with the legacy marker, making the deprecation immediately obvious.
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 has no parameters, no output schema, and performs a simple list operation, the description is complete. It covers purpose, deprecation status, and migration path.
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 zero parameters, and schema description coverage is 100%. The description adds no parameter info (none needed). Baseline for 0 parameters is 4, so a score of 4 is appropriate.
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 lists all browser sessions, using the specific verb 'List' and resource 'browser sessions'. It also distinguishes itself from the sibling tool 'manage_browser_sessions' by marking itself as legacy and directing the agent to that alternative.
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?
The description explicitly tells the agent not to use this tool and provides the exact alternative: 'Use manage_browser_sessions instead.' This is strong, unambiguous guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
