Server Quality Checklist
Latest release: v1.18.2
- Disambiguation4/5
Most tools have clearly distinct purposes, but there is some overlap among memory analysis tools (e.g., analyzeMemgraph, classifyCycle, findCycles, findRetainers) which could be confusing despite their specific roles.
Naming Consistency5/5All tools follow a consistent PascalCase naming convention with a verb+object pattern (e.g., captureMemgraph, classifyCycle, diffMemgraphs). The names are predictable and descriptive.
Tool Count3/528 tools is on the higher side but still reasonable given the diverse domains covered (memory, trace, code, logging, CI). Some tools could potentially be merged, but overall each serves a distinct purpose.
Completeness5/5The toolset provides comprehensive coverage for memory debugging and performance analysis: capture, analyze, classify, diff, verify, code investigation, logging, and CI integration. There are no obvious gaps for the intended domain.
Average 4.2/5 across 28 of 28 tools scored. Lowest: 3.4/5.

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, so the description must fully convey behavioral traits. It states it 'parses' and 'returns' data, implying a non-destructive read operation, but does not mention side effects, permissions, or performance characteristics. The description lacks detail on what happens if the trace is malformed or incompatible.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that efficiently captures the tool's purpose and return values. However, it is dense and could benefit from a more structured format (e.g., bullet points) for better readability.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description lists returned data (aggregates, top allocators, diagnosis) but does not explain the output structure in detail. With no output schema, the description should cover error conditions, prerequisites (e.g., trace must be from Allocations template), and how the diagnosis is formed. The tool is part of a large sibling set, but its niche is clear.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does 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 well. The description adds minor value by providing the xcrun command example for tracePath and clarifying outputFormat values, but does not significantly enhance understanding beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states it parses the 'allocations' schema from a .trace bundle recorded with the Allocations Instruments template. It distinguishes itself from siblings like analyzeMemgraph (which analyzes general heap) and analyzeMemoryFootprint (which focuses on footprint breakdown) by specifying the exact schema and template used.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for analyzing allocation data from a specific trace template, but does not explicitly state when to use this tool versus siblings like analyzeMemgraph, analyzeMemoryFootprint, or compareTracesByPattern. No 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.
- Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the burden. It discloses the underlying command, bounded duration (≤60s), and that it returns parsed entries. However, it does not describe error handling, destructive potential, or other behavioral traits beyond the basic operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise at three sentences, front-loaded with the core purpose. It could benefit from a more structured breakdown of parameters and usage.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the 6 parameters and no output schema, the description is incomplete. It lacks details on return format, parameter semantics beyond duration, and how to interpret parsed entries. The absence of annotations exacerbates the gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 6 parameters with only 17% description coverage (only durationSec has a description). The description adds minimal meaning beyond the schema, mainly repeating the duration constraint and default. It does not explain predicate, process, subsystem, level, or maxEntries.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it wraps `log stream --style compact` for a bounded duration, returns parsed entries, and is useful for capturing a specific user flow. It effectively distinguishes itself from sibling tools like logShow and other analysis tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for capturing user flows without setting up Console.app, but lacks explicit guidance on when not to use or alternatives. It does not mention contexts where it might be inappropriate or provide 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?
Annotations are absent, so the description must carry full behavioral disclosure. It only states 'count instances' and mentions parameter behavior in passing but does not explain that the tool is read-only, return format, side effects, or permissions. The detailed versioning notes are 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.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences: first defines purpose, second covers usage modes and a concrete use case. Concise and front-loaded with no wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite high schema coverage, the description omits contextual details like output structure, error scenarios, or deeper explanation of 'leaked nodes'. For a tool with 9 parameters in a complex domain, more context is needed beyond the schema descriptions.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does 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 references className and topN but adds little beyond the schema. No contradiction with schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool counts class appearances in leaked nodes of a .memgraph file, with specific modes for single class or top N. It includes a use case ('confirm whether a fix actually reduced instance counts') and distinguishes from siblings by focusing on class counts in leaked memory.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives explicit usage guidance: provide className for a single count or omit for top N, and use to verify fix effectiveness. However, it does not discuss alternatives or when not to use this tool, limiting full guideline completeness.
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 states what the tool returns and its pipeline role, but does not mention whether it is read-only, destructive, or requires specific permissions. For a mutation-like analysis tool, this is a gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two paragraphs: first defines functionality, second guides pipeline usage. It is efficient but contains jargon; a slightly more structured format could improve clarity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description lists return fields and pipeline connections, compensating for the lack of output schema. However, it does not detail the structure of the return values beyond names, which may be sufficient given the context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema covers 100% of parameters with descriptions. The description adds no extra parameter information beyond listing return fields, so it meets the baseline but does not exceed it.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool matches each ROOT CYCLE against a catalog of 8 known antipatterns, using specific verbs like 'Match' and 'Returns'. It distinguishes itself from sibling tools like findCycles by focusing on classification against patterns, not just cycle detection.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit instructions on what to do after using the tool ('follow suggestedNextCalls') and hints at a pipeline context. However, it does not specify when not to use this tool or directly compare to alternatives among the many siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It discloses that it parses the trace, returns bucket classification, wakeup count, active-state ratio, and top-N samples. It mentions v1.15+ but does not specify side effects or error handling. Lacks explicit read-only statement, but the nature of trace analysis implies no destructive actions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is relatively concise and front-loaded with the core purpose. It uses brackets to highlight the tool source, and includes version info. Every sentence adds value, though it could be slightly more structured.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema exists, so the description must explain return values. It lists returned items (classification, wakeup count, ratio, top-N) but lacks details on format or structure. For a tool with 3 parameters, this is adequate but not fully complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with descriptions for all three parameters. The description adds context like 'top-N samples by energy cost' but does not provide additional semantic value beyond what the schema already offers. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool parses the energy-impact schema, returns classification and aggregate data, and distinguishes itself from analyzeTimeProfile by specifying it reads the OS power-management subsystem directly. The verb 'Parse' and resource 'energy-impact schema' are specific.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly mentions the use case 'why is my app draining battery?' and distinguishes from analyzeTimeProfile. However, it does not provide guidance on when not to use or alternative tools among the many siblings, but the single distinction is clear.
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?
Discloses that heavy/unsymbolicated traces may crash and describes the returned notice field with workarounds. With no annotations, this provides useful behavioral context, though permissions or other side effects are omitted.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences: the first states the core operation, the second provides a critical caveat. No unnecessary words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Lacks a description of the normal return structure beyond 'top symbols by sample count'. Without an output schema, more detail on the response format would improve completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema covers 100% of parameters with descriptions. The first sentence reinforces the meaning of topN, but adds minimal new meaning beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description explicitly states the action (export time-profile schema and return top symbols) and the resource (.trace bundle). It distinguishes from sibling tools by focusing on time-profile analysis.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5Does 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 analyzeMemgraph. The context is implied but not comparative.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It details the includeReferenceTree parameter, including prerequisites (MallocStackLogging) and behavior changes. It does not mention side effects or resource usage, but overall discloses key behavioral aspects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise with two main sentences and a detailed note for includeReferenceTree. The note is necessary but somewhat lengthy. Overall efficient with no wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema exists, but the description states what is returned ('paths from a top-level node down to the matching node'). It covers the main behavior and the advanced parameter, though it could benefit from more examples or edge cases.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does 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 significant context for includeReferenceTree, but for other parameters (path, className, maxResults) it adds minimal value beyond the schema descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description uses specific verb 'walk' and resource 'retain chains', clearly stating it finds retain chains for a class name substring. It distinguishes itself from siblings like findCycles and analyzeMemgraph by focusing on retainers of a specific class.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description mentions it is 'useful for answering who is keeping <class> alive?', implying when to use, but does not explicitly state when not to use or provide alternatives. Sibling tools are not contrasted.
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 mentions user-in-loop step, polling, timeout, and chained inspectTrace summary, but lacks details on error handling, side effects (e.g., leftover files), or blocking nature. With no annotations, the description carries full burden and provides adequate but not comprehensive transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
Four sentences efficiently cover action, rationale, return values, and timeout. The title provides additional context. Could be slightly more concise (e.g., remove version number), but overall well-structured and front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of a tool requiring user interaction, polling, and chaining, the description sufficiently explains the return structure (instructions, tracePath, inspectTrace summary) and timeout. Missing output schema is compensated. No mention of error states or termination beyond timeout.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with detailed descriptions for each parameter. The description adds minimal value beyond schema, only repeating the timeout default and mentioning the chaining behavior. Baseline 3 is appropriate as schema does the heavy lifting.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: open Instruments.app, prompt user to record/save a .trace, poll watchDir for new bundle, and chain into inspectTrace. It explicitly distinguishes from sibling recordTimeProfile by framing it as a macOS 26.x workaround for the failing xcrun xctrace record.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides context for when to use (macOS 26.x escape hatch) and chaining into inspectTrace, but does not explicitly state when not to use or name alternatives beyond xcrun xctrace record. Sibling list includes recordTimeProfile, but no comparative guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It describes the output (markdown/plaintext hover content and declaration fragment) but does not disclose behavioral traits such as read-only nature, error handling, or performance characteristics. The 'best-effort' qualifier adds some transparency but 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.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise: two sentences that immediately convey the technical identity and a practical use case. Every sentence earns its place without fluff.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite lacking an output schema, the description explains what is returned (markdown/plaintext hover content and declaration fragment). It also gives a concrete usage context. However, it could be more detailed about the return structure or potential failure cases, which prevents a perfect score.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description does not add any meaning beyond the input schema. Schema coverage is 75% (projectRoot lacks description), and the description does not clarify that parameter or provide additional context for other parameters. The description adds zero value for parameter understanding.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it performs a SourceKit-LSP textDocument/hover request at a specific position, which is a specific verb+resource. It distinguishes from sibling tools like swiftGetSymbolDefinition by focusing on hover content and type info, not definitions.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides a explicit use case: disambiguating self captures in closures. However, it does not mention when not to use it or suggest alternatives, which prevents a higher score.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description bears full burden. It describes the tool as parsing and returning data, implying non-destructive behavior. However, it lacks explicit disclosure of behavioral traits such as read-only nature, performance characteristics, or any side effects, which would be helpful for an agent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences long, front-loads the key action and schema, and contains no redundant information. Every sentence adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 5 parameters, full schema coverage, and no output schema, the description adequately conveys the overall purpose and return shape. It could be enhanced by briefly noting the response format options (e.g., JSON/markdown) but is largely complete for typical use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does 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 overall behavioral context (what the tool returns) but does not add specific parameter semantics beyond what is already in the schema. The summary of return values is useful but not parameter-level detail.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states that it parses the `animation-hitches` schema from a `.trace` bundle, enumerates the outputs (hitch totals, by-type counts, longest hitches, 100ms threshold crossing), and implicitly distinguishes itself from siblings like `analyzeHangs` or `analyzeTimeProfile` by its specific domain.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for animation hitch analysis from a specific `.trace` bundle recorded with the Animation Hitches template, providing clear context. However, it doesn't explicitly exclude other scenarios or compare directly with sibling tools, leaving some ambiguity about when to prefer this over others.
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 present, so the description carries full burden. It describes parsing and returning data but does not explicitly state whether the operation is read-only, or disclose side effects, error handling, or limitations. However, the name 'analyze' suggests non-destructive behavior, and the description is adequate for an analysis tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences long, front-loaded with the action ('Parse the app-launch schema') and followed by a list of returned data. Every word is informative with no redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has only two parameters, no output schema, and no annotations, the description adequately covers purpose, input requirements, and output contents. It is missing error conditions or usage examples, but for a focused analysis tool it is largely complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does 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 minimal value beyond the schema for 'tracePath' (same info) and some added context for 'outputFormat' (default behavior and special case for other tools). Overall, it does not significantly enhance parameter understanding.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description uses specific verbs ('Parse', 'Returns') and explicitly names the resource ('app-launch schema from a .trace recorded with the App Launch Instruments template'). It clearly distinguishes from siblings like 'analyzeAllocations' by specifying the template. The output contents (total launch time, type, per-phase breakdown, slowest phase) are detailed.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description clearly states the input must be a .trace file recorded with the App Launch template, providing clear context. It does not explicitly state when not to use this tool or list alternatives, but the sibling tool names imply each analyze tool targets a specific template.
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 the full burden for behavioral disclosure. It clarifies that the tool parses a trace file and returns analysis results, implying a read-only operation. However, it does not explicitly address error handling (e.g., invalid trace path, missing leaks data), performance implications, or required permissions. The behavioral information 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.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is exceptionally concise: three sentences plus a version note. It front-loads the core action ('Parse the leaks schema from a .trace'), immediately distinguishes from alternatives, lists outputs, and gives a concrete use case. Every sentence is essential and no information is repeated or wasted.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has 3 parameters, no output schema, and no annotations, the description provides a solid overview of purpose, output, and differentiation. It describes what the tool returns (four specific metrics), which partially compensates for the missing output schema. However, it does not cover possible errors, performance when processing large traces, or the exact format of timestamps, leaving minor gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents each parameter. The description adds value by explaining the return shape (per-class first-seen-at, peak counts), which helps contextualize the 'topN' parameter. However, it does not elaborate further on the parameters beyond their schema descriptions. With full schema coverage, this is a baseline score.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it parses the 'leaks' schema from a .trace recorded with a Leaks template, distinguishes it from the leaks(1) CLI snapshot by emphasizing it's a time series, and specifies the exact outputs (per-class first-seen-at timestamp, peak instance count, peak bytes, event count). This makes the purpose unambiguous and distinguishes it from sibling tools like analyzeAbandonedMemory or detectLeaksInXCTest.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly contrasts this tool with the leaks(1) CLI snapshot and provides a concrete use case: answering 'when in the timeline did the leak appear?' which the snapshot cannot. However, it does not explicitly state when not to use this tool or compare it to sibling tools within the same suite (e.g., analyzeMemgraph), but the context is sufficient for an AI agent to infer appropriate usage.
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, description carries burden. It describes outputs and version info but omits side effects, authentication needs, or read-only nature. Adequate but not explicit.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Four sentences, each providing distinct value. Front-loaded with specific verb and resource, no redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, description covers key return values and dependencies. Missing error handling or prerequisites beyond trace path, but sufficient for typical use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Given 4 params, nested object, and no output schema, the description covers the algorithm, fallback, and typical use case. Lacks explicit return format (e.g., file path and line number), but 'Returns the position' is adequate. Complete enough for the complexity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, baseline 3. Description adds meaning for all parameters: explains symbolName types, hint usage, projectRoot override, and candidatePaths as a speedup. Exceeds baseline by explaining the two-step search process.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states it finds the file:line where a Swift symbol is declared, using specific verb-resource pairs. Distinguishes from siblings like swiftFindSymbolReferences by mentioning typical use after findRetainers/classifyCycle.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly says to use after findRetainers/classifyCycle to land in source file. Provides guidance on candidatePaths and hint to speed up search. Does not list alternative tools for different purposes, but implies context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Describes the underlying command (leaks), resolution via pgrep, and the write action. Lacks details on side effects (e.g., process pause) or error handling, but with no annotations, this is a solid disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Single concise paragraph front-loading purpose and key mechanics. Every sentence adds value; no redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and no annotations, the description fully covers purpose, parameter usage, constraints, and limitations. Provides complete guidance for an agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema already documents all 3 parameters with 100% coverage. Description adds valuable context: mutual exclusivity of pid and appName, resolution via pgrep, and implicit output extension requirement.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states it captures a .memgraph from a running process using `leaks --outputGraph`. Distinguishes from sibling tools like analyzeMemgraph or diffMemgraphs by focusing on capture.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly notes it only works on local Mac and iOS simulator, not physical devices, and directs users to Xcode's Memory Graph button for that case. Provides clear when-to-use/when-not-to-use guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Despite no annotations, the description transparently explains the tool's behavior: it runs xctrace export for potential-hangs schema, and optionally exports time-profile schema in parallel when includeStackClassification is true, with graceful fallback. It also describes the enrichment process and the effect of parameters.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single focused paragraph that is well-structured: starts with the core purpose and then systematically details parameters and usage. Every sentence adds value, with no fluff.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Without an output schema, the description fully explains the return values (aggregated stats and top N hangs with optional enrichment). It covers all parameters, including the newer includeStackClassification and outputFormat, and mentions fallback behavior, making it complete for the tool's functionality.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, but the description adds significant meaning beyond the schema by explaining the pipeline for topFramesByHangStartNs, the recommendation for minDurationMs, and the behavior of includeStackClassification and outputFormat options.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool analyzes potential hangs from .trace bundles by running xctrace export and returning aggregated stats and top hangs. It distinguishes from siblings like analyzeTimeProfile by focusing specifically on hang analysis.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides explicit guidance on when to use parameters: suggests minDurationMs:250 for user-visible hangs, explains the typical pipeline with analyzeTimeProfile, and clarifies that includeStackClassification supersedes topFramesByHangStartNs for most callers.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
