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

With no annotations provided, the description carries the behavioral burden. It usefully discloses that write operations require confirmation, which signals a side-effect gate. However, it does not describe response behavior, error handling, authentication expectations, or the fact that the underlying operations may create, update, or delete data beyond the generic 'writes' label.

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 short sentences, no filler. The core invocation pattern is front-loaded, and the safety-relevant confirmation requirement is stated clearly. Every part of the description 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?

This is a dynamic API-call tool with 7 parameters, no annotations, and no output schema, yet the description is very minimal. It does not mention how to discover valid operationIds using jaicp_operations, what the return value looks like, whether responses are raw, or what happens on invalid specs. The sibling tools help, but the description itself leaves too much unsaid for an agent to invoke the right operation confidently.

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 only 14%, and the description compensates only for spec, operationId, and confirm. The meaningful parameters body, query, headers, and pathParams receive no semantic guidance, and there is no explanation of how they map to a given operation. The confirm statement also adds less detail than the schema already provides.

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 action ('Call') and a specific resource ('JAICP OpenAPI operation by spec id + operationId'), which clearly distinguishes it from the sibling discovery tools jaicp_specs and jaicp_operations. It is immediately obvious what the tool does and how it differs from nearby 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 gives clear context for when to use the tool: once a spec and operationId are known, it executes that operation. It also adds an important condition for write operations ('Writes need confirm=true'). It does not explicitly name alternatives or provide a when-not-to-use rule, 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.

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

No annotations are present, so the description carries the full burden. The verb 'List' conveys a read-only operation and the description names the search dimensions, but it does not disclose what happens when search is omitted, the output shape, ordering, or edge cases. This 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.

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

Two sentences with no filler. The primary purpose is front-loaded and the optional search behavior is stated directly. Every word 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 two-parameter listing tool, the description is sufficient for an agent to select and invoke it correctly. The spec enum is in the schema, and the description explains the optional search behavior. The absence of an output schema is mitigated by the clear 'List operations' framing.

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 0%, so the description must compensate. It adds real meaning to the search parameter by specifying it can filter over operationId, path, and summary, which is not inferable from the schema. For 'spec', the schema's enum already documents valid values, while 'from one spec' clarifies its role.

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 tool lists OpenAPI operations from a single spec and outlines searchable fields. It is specific about the verb and resource, but it does not explicitly contrast with the sibling tools (e.g., jaicp_specs for listing specs, jaicp_call for invoking an operation), so sibling differentiation is left implied rather than stated.

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 phrase 'from one spec' gives a clear usage context: use this tool when you need operations belonging to a specific spec. However, there is no explicit guidance about when not to use it or which sibling tool should be chosen instead, such as jaicp_specs for finding available specs.

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 usefully discloses that the tool makes no network calls and that the content is official specifications, which signals a read-only, offline operation. However, it does not describe the response format, size, or what an agent should expect back beyond the vague notion of 'specs'.

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 short sentences deliver the essential information with no filler. The authoritative provenance ('Official JAICP OpenAPI specs') and the key behavioral constraint ('No network') are both stated up front and compactly.

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 zero-parameter informational tool, the description is close to complete: it names what the tool provides and flags the offline nature. Without an output schema, a bit more detail about the returned representation would strengthen it, but the scope is small enough that an agent can reasonably infer what this tool is for.

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 parameter-level explanation is unnecessary. The description does not need to add schema meaning, and the baseline of 4 for parameterless tools applies here.

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 identifies a specific resource ('official JAICP OpenAPI specs') and clearly indicates the tool provides the specification this MCP was built from. It does not use a strong verb like 'retrieve' or 'return', and it does not explicitly contrast with sibling tools, but the resource is clear enough for an agent to distinguish it from 'jaicp_operations' and 'jaicp_call'.

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 gives no guidance on when to use this tool versus the sibling tools. 'No network' vaguely implies this is a safe/local source of information, but there is no explicit when-to-use or when-not-to-use statement, and no mention of alternatives.

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