AISOTools

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full transparency burden. It discloses the key behavior: a side-by-side comparison of 2-5 tools covering pricing, rating, features, and pros/cons. It does not describe output format or failure modes, but these are minor for a non-destructive comparison tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, front-loaded sentence with no filler. It states the action, scope, output dimensions, and usage trigger efficiently, so every part earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a one-parameter tool with no output schema, the description covers purpose, parameter range, output contents, and the trigger condition. It does not specify response formatting or edge-case handling, but nothing essential for selecting and invoking the tool is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

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 echoes the 2-5 count but does not add substantial meaning beyond what the schema already provides about the 'tools' parameter.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: 'Side-by-side comparison of 2-5 AI tools.' It also lists concrete output dimensions (pricing, rating, features, pros and cons), which clearly distinguishes this tool from siblings like get_ai_tool or search_ai_tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides an explicit trigger condition: 'Use when the user is choosing between named products.' It does not explicitly mention alternatives or when not to use the tool, but the intended context is clear enough for an agent to select it appropriately.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations to carry the behavioral burden, the description discloses how results are drawn (curated alternative lists, falling back to same-category tools) and frames the tool as a recommendation lookup. It doesn't detail result shape or empty-result behavior, but no destructive or permission-sensitive behavior needs flagging.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, zero filler: the first states the core behavior and source logic, the second states the exact user intent it serves. It is front-loaded and every clause earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a low-complexity lookup tool with a fully described 2-parameter schema, the description covers purpose, source, fallback behavior, and usage context. The only minor omission is a statement of return value shape, but the simple result ('alternatives') is evident and no output schema is expected.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already documents both parameters at 100% coverage, including slug/display name for tool and the 1-20 range/default for limit. The description only adds the conceptual role of the input without extra parameter details, matching the baseline for strong schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly identifies the resource and outcome: alternatives for a given AI tool, sourced from curated lists with same-category fallback. The 'replace or switch off' use case and the contrast with compare/get/list/search siblings make the tool's specific role unambiguous, even without an explicit verb.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

'Use when the user wants to replace or switch off a product' gives an explicit trigger condition. It doesn't enumerate when-not-to-use or name sibling alternatives, but the context is clear and sufficient for routing.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of explaining behavior. It discloses the output contents in useful detail (pros, cons, pricing tiers, alternatives) and notes input flexibility (slug or display name). It does not mention error behavior for unknown tools, but for a simple lookup tool this is a reasonable level of transparency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences with no filler. The first sentence states the primary purpose and output fields, and the second sentence gives the invocation detail. It is front-loaded and every sentence contributes useful information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a one-parameter lookup with no output schema, the description adequately explains what will be returned and how to specify the tool. It could more explicitly address the relationship to find_ai_tool_alternatives since 'alternatives' appears both as an output field and as a sibling tool name, but this is a minor gap rather than a serious omission.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already fully documents the single parameter, including examples ('claude-code', 'Claude Code') and the accepted forms. The description repeats this idea without adding new semantic detail such as matching behavior, case sensitivity, or uniqueness. This meets the baseline for high schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('get') and resource ('AI tool') and explicitly enumerates what a full catalog record includes: description, features, pros, cons, best-for, pricing tiers, and alternatives. It clearly distinguishes this from siblings like compare_ai_tools, find_ai_tool_alternatives, and search_ai_tools by emphasizing a single tool lookup.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description makes the usage context clear: call this when you need the full catalog record for one AI tool. It does not explicitly say 'do not use this for comparing or searching,' but the focus on 'one AI tool' and the listed sibling names imply the boundary. It also specifies the accepted identifiers (slug or display name), which is practical invocation guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the behavioral disclosure burden. It explains what the response contains (categories with slugs, subcategories, and tool counts) and implies a read-only catalog operation, which is sufficient for a zero-parameter list tool with no destructive side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences, front-loads the core purpose, and adds only one actionable usage note. Every clause earns its place without fluff or repetition of the tool name.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a parameterless list tool with no output schema, the description fully covers what the caller gets and how to use it. There are no missing parameters, prerequisites, or complex behaviors that would require further explanation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has zero parameters, so there is nothing for the description to explain param-by-param. The baseline for parameterless tools is 4, and the description appropriately focuses on output rather than input semantics.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: it lists every category in the AISOTools catalog, along with slug, subcategories, and tool counts. It also distinguishes itself from sibling tools by targeting category listing rather than searching, comparing, or retrieving individual tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description clearly says to use the returned slugs to filter search_ai_tools, giving a concrete downstream use case. It does not explicitly state when not to use this tool relative to every sibling, but the primary workflow guidance is present and actionable.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the behavioral disclosure burden. It covers important runtime behavior well: result paging semantics (matched/returned/truncated), the max-limit advice, and the fact that results are ranked summaries with canonical URLs. It omits ranking criteria and error/rate-limit behavior, but these are less critical for a read-only catalog search.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences, each with a clear job: what the tool searches, what it returns, and how to handle truncation. The critical 'do not tell the user the catalog only contains...' warning is a targeted behavioral caveat, not filler. Nothing feels redundant.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a four-parameter optional search tool with no output schema, the description is largely complete: use case, result semantics, canonical page, and truncation handling are all addressed. Remaining gaps are minor, such as unspecified ranking criteria and no mention of error or authorization behavior.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

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 value by connecting the search dimensions to query, category, and pricing, and by giving the limit parameter actionable context: when truncated is true, raise limit up to 50. This goes modestly beyond the schema's own descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action (Search), the resource (AISOTools catalog), and the filtering dimensions (keyword, category, pricing model), plus what is returned (ranked summaries with canonical pages). It implies it is the broad entry point but does not explicitly name or contrast sibling tools, so differentiation is slightly less strong.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives an explicit when-to-use cue: 'Use this first when the user asks which AI tool does something.' It also provides a concrete conditional instruction for truncated results (raise limit). It does not explicitly list alternatives or state when not to use this tool, so it stops short of a 5.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
