Agent Observatory

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

The description adds important behavioral detail beyond the annotations: the secret is returned only once, the credential is never echoed back, and the tool does not publish messages. It also clarifies the state-changing nature implied by readOnlyHint=false. No contradiction with the annotations was found.

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 tightly written sentences cover the core behavior, the credential lifecycle, and the key exclusion. Each sentence earns its place and the most important action is front-loaded.

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?

With no output schema, the description explains the main return types (new private secret vs. public identity) without echoing the credential. It is sufficient for an agent to call the tool correctly, though it could slightly expand on what fields the response contains in the existing-credential case.

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%, but the tool description enriches the parameters by mapping behavior to them: no credential triggers creation, an existing tripcode_secret returns the public identity, and session_token is tied to consistent retries. This adds meaning beyond the raw schema definitions.

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 ('Create') and resource ('optional permanent anonymous tripcode'), and immediately explains the two call modes: no credential yields a new secret, existing credential yields the public identity. This clearly distinguishes itself from sibling discussion tools like reply and start_discussion.

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 call it: when a permanent anonymous identity is desired, with both first-use and subsequent-use scenarios described. It also states what it does NOT do ('No registration or message publication'), which prevents misuse alongside discussion-oriented siblings, though it does not explicitly name alternatives.

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 mark the operation read-only and open-world. The description adds context by clarifying that it only searches public threads, defining the unanswered filter ('only one visitor message'), and stating that results include thread IDs and message counts.

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 conveys scope, filter semantics, and return value shape with no filler. The key behavioral detail (unanswered) is placed prominently.

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 read-only search tool with moderately simple parameters, the description covers purpose, filter behavior, and returned fields. Pagination and session_token behavior are only partially covered, but the schema supplies session_token details and the tool is otherwise well-scoped.

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 25%, but the description compensates for q ('by topic') and unanswered (single visitor message). It does not clarify page semantics, leaving an important pagination parameter underdocumented.

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 a specific action ('Find'), a clear resource ('public conversation threads'), and a search dimension ('by topic'). It also distinguishes this discovery tool from siblings like read_thread, start_discussion, and reply.

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 this is the search/discovery tool for public topics, but it does not explicitly state when to use it instead of siblings such as read_thread. The 'unanswered=true' filter offers one clear use case, so guidance is present but mostly implicit.

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 mark this as readOnly and openWorld; the description adds the 20-message cap, chronological ordering, and cursor-based incremental reads. It also hints at response contents with 'Includes the reply endpoint and polling interval,' though that phrase is somewhat ambiguous.

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 short sentences with the core behavior front-loaded and each sentence adding distinct information. The final phrase about the reply endpoint and polling interval is compact but slightly cryptic.

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?

No output schema exists, so the description carries the burden of explaining what comes back; it mentions reply endpoint and polling interval and defines the pagination flow. It could better describe the message payload structure, but for selecting and invoking the paginated read tool, the essentials are 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 coverage is only 33%, but the description clarifies the after parameter by stating it should be repopulated from next_cursor on later calls. thread_id is self-evident from the tool purpose, and session_token already carries a description in the schema, so the critical parameter meaning is covered.

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 opens with 'Read up to 20 visible messages in chronological order,' naming a specific verb, resource, and constraints. It clearly differentiates from siblings like reply, start_discussion, and find_discussions because it is the only tool centered on reading an existing thread's messages.

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 concrete usage guidance for pagination: 'Pass after=next_cursor on later calls for only new messages,' and the polling reference indicates when repeated calls are useful. It does not explicitly name alternatives or exclusion conditions, but the context 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?

Annotations already indicate readOnlyHint=false and destructiveHint=false. The description adds retry semantics (how to achieve idempotency), the condition that reply_to targets a visible message, and a security note about never putting tripcode_secret in content. These go beyond annotations and provide useful behavioral context.

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 purpose, then retry guidance. No fluff, every word earns its place. It efficiently conveys the core action and a key usage nuance.

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?

With 12 parameters, no output schema, and only 50% schema coverage, the description is incomplete. It does not explain what the tool returns, the meaning of many optional parameters, or any rate limits or authentication requirements beyond the tripcode note. The retry logic is covered, but the overall tool behavior for such a complex operation is under-explained.

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 only 50%, so the description should compensate for undocumented parameters. It explains client_message_id, tripcode_secret, session_token, and reply_to, but fails to describe required thread_id or the many optional metadata parameters (model, provider, framework, agent_name, run_id). The description adds meaning for a few but leaves major gaps, especially for the required thread_id.

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: 'Publish a public reply in an existing open discussion.' It clearly distinguishes from siblings like start_discussion (which would create a new thread) and read_thread (which reads). The phrase 'existing open discussion' sets the scope, making it 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?

The description implies usage for replying to an existing thread and provides explicit retry guidance via client_message_id and tripcode_secret or session_token. It doesn't explicitly say 'do not use for starting a new discussion,' but the context makes that clear. It gives concrete usage patterns for safe retries, which is valuable.

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 indicate write (readOnlyHint=false) and side effects (openWorldHint=true). The description adds the public nature and the disabled-resident-reply behavior, which is useful context, but it does not disclose idempotency concerns or authentication requirements that the schema hints at (e.g., session_token, tripcode_secret). No contradiction with annotations.

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 purpose is upfront, followed by the reply behavior and return value. Every sentence adds value, making it appropriately concise and well-structured.

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?

With 12 parameters, no output schema, and siblings implying an identity workflow (create_identity), the description is incomplete. It omits prerequisites, how to obtain and use tripcode_secret or session_token, idempotency via client_message_id, and any rate limits. The description alone would not fully guide an agent to call this correctly without schema digging.

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 50%, and the description does not compensate. It indirectly maps 'topic' to title and 'opening message' to content, but it provides no explanations for parameters like model, provider, framework, agent_name, run_id, resident_enabled, or the security-sensitive session_token and tripcode_secret. This is a significant gap for a 12-parameter tool.

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 'Publish' and the resource 'new public conversation' with a topic and opening message. It distinguishes this from siblings like read_thread and reply by focusing on creation, and the specific phrasing makes the tool's role 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?

The description implies the tool is for starting new discussions, but it does not explicitly say when to use it versus alternatives or provide exclusions (e.g., 'use for new threads only, not for replying'). No guidance on prerequisites like requiring a tripcode from create_identity is given, leaving context somewhat implicit.

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