Ricuicui

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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered and the bar is lower. The description adds that results are scoped to specific platform builds (Apple Silicon, Intel, Windows), which is useful content disclosure, but says nothing about freshness, caching, or whether a version number accompanies the links.

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?

A single well-formed sentence with the resource and platform scope front-loaded and no filler. It could have been split to add usage guidance, but nothing present is wasted.

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 simple read-only lookup with one optional enum parameter and no output schema, the definition is close to sufficient. It still leaves the return shape ambiguous — whether the response is a version string, a list of URLs, or both — which an agent needs to know to present results.

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% and the single 'language' parameter is documented with its enum and French default, so the schema carries the meaning. The description adds nothing about the parameter, which is acceptable at full coverage but leaves it at baseline.

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 names the resource (Ricuicui version) and the payload (download pages for Mac Apple Silicon, Intel, and Windows), so the agent knows exactly what comes back. It is clear enough to separate this from my_account and read_documentation, though the verb is 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?

There is no guidance on when to call this versus the sibling tools, and no mention of prerequisites or typical phrasing of a user request that should trigger it. The agent must infer usage purely from the resource name.

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?

Beyond the readOnlyHint/openWorldHint annotations, the description discloses a concrete auth requirement — an Authorization: Bearer rcc_… header with a token created in My account after licence purchase. That is real operational context an agent needs before calling. It stops short of describing response shape or failure behavior, but annotations already cover the safety profile.

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, front-loaded with the return content and followed by the auth prerequisite. The parenthetical about token creation is slightly wordy but earns its place by telling the agent where the credential comes from.

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 read with no output schema, the description covers the essentials: what is returned, for which account, and how to authenticate. It could add a note on what a licence entry looks like, but nothing needed to call it correctly 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?

The tool takes no parameters, so the baseline is 4. The description correctly adds nothing about inputs and instead spends its words on the auth context, which is the only 'parameter-like' detail relevant 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 states what the tool returns (e-mail and licences) and for whom (the account owning the API token), which is specific enough for an agent to recognize a 'who am I / what am I licensed for' tool. It does not name an explicit verb such as 'get' and does not reference siblings, but the resource is unambiguous.

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?

Usage is only implied: an agent can infer this is the tool for identifying the token's account, but the description never says when to prefer it over siblings like get_latest_version or read_documentation. No explicit exclusions or preconditions beyond the auth note.

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?

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds genuinely new behavioral information: the tool's output depends on whether a guide is supplied, returning a list of guides or the guide text. With no output schema, this dual-mode disclosure is the main thing an agent needs and it is present.

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?

A single compact sentence covering both modes, front-loaded with the resource name. Nothing is redundant, though the opening noun fragment is slightly cryptic and could have been fused more clearly with the mode logic.

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 simple two-parameter read tool with annotations covering safety and a description covering return shape, this is close to complete. Minor gaps: what the listing actually looks like and whether the language parameter affects guide selection or only the answer 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 coverage is 100% with both parameters enum-constrained and documented, so the baseline is 3. The description does add the important semantic that the guide parameter is optional and its absence triggers listing rather than an error, which the schema alone (no required array) does not make obvious.

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?

Uses a specific verb (read) and names the exact resource (Ricuicui user documentation), then splits the two operating modes: with vs. without a guide. Sibling tools (get_latest_version, my_account) are unrelated, so no differentiation is needed. The only blemish is the terse opening fragment, which reads like a label rather than a purpose statement.

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 implicitly tells the agent how to invoke each mode (omit the guide to list, supply one to read), which is useful usage context. However, it never states when this tool is appropriate versus other tools, nor any prerequisite such as needing to list guides before reading one. Guidance is implied, not explicit.

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