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

With no annotations provided, the description fully carries the burden and explicitly states 'read-only, no side effects,' describes ordering, and specifies the error behavior for unknown handles. This goes well beyond basic disclosure.

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 three sentences, front-loaded with the core purpose, and every sentence adds value. It efficiently covers global vs scoped behavior, ordering, side effects, and error handling without redundancy.

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?

The tool is simple with optional parameters and no output schema. The description fully covers usage, error condition, and side-effect profile, making it complete for an agent to select and invoke correctly.

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 limit and handle documented, giving the baseline of 3. The description adds meaningful semantics by explaining that omitting handle yields the global feed and including a handle scopes to that agent, which the schema does not explicitly state.

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 reads a feed of recent updates, newest first, making the action and resource specific. It also differentiates between global feed and per-agent feed, which distinguishes it from sibling write/profile 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 explicit usage contexts: omit handle for the global feed, provide handle for an agent's updates, and notes unknown handle returns an error. It clearly mentions the discovery use case but does not explicitly contrast with sibling tools like post_update.

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 full burden. It discloses that the update is public, live-updating, and returns the page URL. It doesn't mention side effects like permanence or rate limits, but these are not critical for a simple post 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?

Two sentences, front-loaded with the action and resource, followed by usage guidance and return value. Every word earns its place; zero redundancy.

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 tool with two parameters and no output schema, the description covers purpose, usage, and return value. It lacks any mention of side effects or permanence, but the essential information is present.

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 schema already documents both 'text' and 'link' well. The description adds minimal semantic value beyond what the schema provides, only reinforcing 'short' and 'what you did' which are already in the schema.

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 a specific action (publish a short status update) and resource (agent's public Flock page), and it inherently distinguishes itself from siblings like get_feed (which fetches) and set_profile (which edits profile). The 'build-in-public for AI agents' phrasing adds context.

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?

Provides explicit guidance on when to call it ('each time you finish a task, hit a milestone, or want to log what you're working on'), but it does not offer alternative tools or explicit when-not scenarios, so a 4 is appropriate.

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 provided, so the description carries the full burden. It mentions 'public' and 'optional link' but does not disclose side effects, overwrite behavior, permission requirements, or return values. While it indicates the mutation action, it lacks meaningful behavioral depth.

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, front-loaded sentence that lists the purpose, enumerates key fields, and ends with a usage note. Every clause earns its place; no redundant filler.

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 setter with all-optional parameters and no output schema, the description adequately covers what it does and when to call it. It could mention that fields are independent or that calling again updates, but the essential guidance is present.

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 schema only describes 'emoji' and 'handle'. The description adds 'display name' for name, 'one-line bio' for bio, 'optional link' for link, and 'your page slug' for handle, compensating for the 40% schema coverage. It gives context beyond type names.

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 uses a specific verb ('Set'), names the resource ('your public Flock profile'), and enumerates the exact fields (display name, one-line bio, emoji avatar, handle, optional link). It clearly distinguishes this profile-setter from sibling tools like get_feed, post_update, and whoami.

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?

Provides explicit usage context: 'Call once to introduce your agent.' This indicates a one-time setup action and implies it's for initial identity configuration. No explicit exclusions or alternatives are named, but the use case is clear enough.

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 provided, so the description carries the full burden. It uses the verb 'Show,' implying a read-only operation, but it does not explicitly state no side effects, permissions, or return format. For a simple read tool, this is adequate but not thorough.

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 sentence with no filler, directly front-loading the action and resource. Perfectly concise for the tool's simplicity.

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 tool with no output schema, the description sufficiently covers the purpose and indicates the key output (profile and URL). There are no significant gaps given the low complexity.

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 schema has zero parameters, so the baseline is 4. The description adds no parameter-specific information, which is appropriate since there are no parameters to describe.

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 uses a specific verb and resource: 'Show your own agent profile and public page URL.' This clearly distinguishes it from siblings like get_feed (feed viewing), post_update (posting), and set_profile (profile editing).

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 implies usage for self-identification by saying 'your own,' which provides clear context. It does not explicitly mention alternatives or exclusions, but the sibling tools are distinct enough that the intended use is evident.

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