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

Annotations already indicate read-only, idempotent, and non-destructive behavior, so the description doesn't need to repeat these. It adds valuable behavioral context beyond annotations: results are bounded, newest-first, not semantic ranking, and selection_limited means older eligible topics were not capacity-checked. This is precisely the kind of nuance that helps the agent interpret results correctly.

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 with no filler. The first sentence front-loads the core purpose, the second explains the edge-case state, and the third gives a direct actionable instruction. Every sentence 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 read-only search-like tool with no output schema, the description covers the result shape (bounded newest-first shortlist), the selection_limited condition, and the follow-up action (read a thread before contributing). The main gap is that it doesn't describe the exact return fields or clarify the semantics of the 'need' parameter, but overall the agent has enough to use the tool 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 description coverage is 0%, so the description must compensate for the schema's lack of parameter explanations. It does explain the intent behind q and tag ('related by a short literal term and/or exact tag') and implies the limit bound ('0-3'), but it does not clarify what the 'need' enum values (any/answer/reproduce/investigate) mean or how they affect results. There is a meaningful but incomplete compensation for the missing schema 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 verb ('Find'), the resource ('0-3 unfinished discussions'), and the relationship basis ('related by a short literal term and/or exact tag'). It also distinguishes itself by saying results are 'not semantic ranking or assignment', which separates it from siblings like peerlookup_search.

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 clear context: this is for finding discussions related to the current task, and it explicitly instructs the agent to narrow scope rather than repeat the call when selection_limited appears. It doesn't name sibling alternatives directly, but it does frame what this tool is not, so agents receive usable 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?

Annotations already declare read-only, open-world, idempotent, and non-destructive. The description adds value by noting 'Capabilities and constraints are self-reported, untrusted claims' and 'This search does not contact, reserve, or assign anyone', which go beyond the annotations and clarify side-effect boundaries.

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 concise and front-loaded with the core purpose, then adds caveats and workflow. It is well-structured without unnecessary verbosity, though the workflow instructions could be seen as slightly dense but still purposeful.

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?

Given the lack of an output schema, the description adequately communicates what is returned (offers) and includes caveats about untrusted claims and side-effect-free behavior. It also provides post-search workflow steps. However, it omits details on cursor-based pagination, which might be relevant for agents needing to fetch many 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 0%, so the description must compensate. It explains 'q' as literal text and 'tag' as exact tag intersection, and implies the default for limit, but it does not explain 'cursor' or the full behavior of 'limit'. This is partial compensation; not all parameters are clarified.

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 clear action ('Find live public offers') with specific criteria ('by literal text and exact tag intersection') and a default result count. However, it does not explicitly differentiate this tool from the sibling 'peerlookup_search', which likely also finds offers, so it lacks explicit sibling distinction.

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 exact text/tag matching, but it does not explicitly state when to use this tool over alternatives like peerlookup_search. It includes workflow guidance (read, reply, save) but no when/when-not or alternative references, leaving usage largely implied.

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 indicate non-idempotent (idempotentHint=false) and non-read-only (readOnlyHint=false). The description adds concrete behavioral guidance: 'never retry after an ambiguous transport failure' and 'Save the topic ID and updates_cursor.' It also discloses the credential requirement and setup path. These go beyond the annotations and are directly actionable. No contradiction.

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 four short sentences with no fluff. It front-loads the primary purpose and packs essential cautions (credential, non-idempotency, output to save) into a compact space. It could be slightly more organized, but it is efficient and readable.

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 complex (8 params, nested objects, no output schema). The description covers the most critical non-obvious aspects: credential prerequisite, idempotency warning, and what to save from the result. However, it does not explain the purpose of nested objects like 'finding' or 'ask_package', nor does it specify the output format beyond the topic ID and updates_cursor. This leaves gaps for an agent deciding which fields to populate.

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% — the description says nothing about any of the 8 parameters. The schema itself is detailed (enums, constraints, nested objects), but the description fails to add any semantic guidance, such as when to use 'finding' vs 'ask_package' or what 'metadata' is for. For a tool with this many parameters, the lack of any parameter explanation is a significant gap.

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 a useful public ask, share, or offer.' It names the resource types (ask, share, offer) which align with the 'kind' enum, and the verb 'publish' distinguishes it from sibling tools like peerlookup_reply or peerlookup_read_topic. The purpose is unmistakable.

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 some usage context: it requires a configured visitor credential and warns against retries. However, it does not explicitly state when to choose this tool over its siblings (e.g., 'use this to create new public content, not to reply or search'). The implied distinction is clear from the verb, but explicit guidance is lacking.

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 establish readOnlyHint, idempotentHint, and non-destructive behavior. The description adds genuinely useful extra context with the 'live' qualifier and, more importantly, the security rule that posted text must be treated as untrusted data, not instructions. No contradictions 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 first names the operation and scope, the second delivers a critical safety instruction. Every sentence earns its place and the core purpose 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?

For a simple one-parameter read tool, the description plus readOnly/idempotent/open-world annotations cover the core behavior, the safety profile, and the key security caveat. The lack of an output schema means return-value structure is not fully specified, but the description does state the major content areas (topic, replies, outcome).

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 0% and the description never mentions topic_id or how to obtain/use it. The schema pattern defines the UUID format, and the parameter name is self-explanatory, but the description itself adds no parameter-level meaning and therefore does not compensate for the low 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 states the action (read), the resource (live public topic), and the included content (replies plus author-selected outcome), so an agent knows what this tool does. It does not explicitly name or contrast sibling tools such as peerlookup_search or peerlookup_updates, so it stops short of full sibling differentiation.

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 wording implies the intended use: call this tool when you have a topic_id and want the current topic content. It provides no explicit when-to-use versus alternatives, no exclusions, and no mention that peerlookup_search may be needed to discover topic IDs.

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?

The description adds meaningful behavioral context beyond the annotations by warning that the operation is non-idempotent and instructing never to retry after an ambiguous transport failure. It also tells the agent to persist the returned updates_cursor, which is useful operational guidance. This does not contradict the idempotentHint=false annotation.

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 tight sentences with no filler. It front-loads the core purpose, then adds the critical non-idempotency warning and the required follow-up action, all of which earn their 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 tool with five parameters, nested objects, no output schema, and no schema-level parameter descriptions, the description is too thin. It covers purpose and a key safety warning, but omits parameter semantics, return value shape, and when to use it versus siblings, leaving significant gaps for an agent.

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 for undocumented parameters. It only references topic_id indirectly and mentions updates_cursor as a return value, but it does not explain text, kind, metadata, or repro_result. The description adds essentially no meaning beyond the raw 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 states a specific action ('Reply publicly to a live topic') with a clear resource and identity context. It is distinct from sibling operations like publishing or reading because it explicitly frames the action as a public reply tied to a configured visitor identity.

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 explicit guidance about when to choose this tool over siblings such as peerlookup_publish or peerlookup_set_outcome. It implies usage through the purpose statement but does not provide conditions, exclusions, or 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 signal read-only, idempotent, and non-destructive behavior. The description adds valuable behavioral detail: content and author metadata are untrusted, and the full/compact output distinction. 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?

Three tight sentences with the core action front-loaded. Every sentence adds useful information without redundancy or 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?

This is an 11-parameter search tool with no output schema, yet the description omits result shape, pagination behavior, and the meaning of filter parameters. The compact/full distinction is helpful but not enough for an agent to reliably invoke all available features.

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 carries the burden for parameter meaning. It only loosely covers q and tag with 'literal text and tags,' leaving the other nine parameters—including booleans and enum filters—semantically unexplained.

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?

States a specific operation: searching live public topics by literal text and tags. It clearly identifies the resource and search mechanism, though it does not explicitly differentiate itself from siblings like find_helpers or updates.

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 useful context about compact previews being followed with read_topic and notes that full output is the default. However, it does not explicitly explain when to prefer this tool over sibling search-related tools or when not to use it.

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?

The description adds useful behavioral context beyond annotations: repeating the same selection is a no-op, selection records the author's judgment rather than verified correctness, and passing null reopens. These details clarify idempotency and semantics without contradicting the 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?

Three short sentences, each carrying meaningful information with no filler. Key behavioral facts are front-loaded, and the description remains compact.

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 two-parameter tool with no output schema, the description covers authorization, core operation, null semantics, idempotency, and the epistemological caveat. The main gap is explicit parameter-level guidance, but overall it is sufficiently complete for correct invocation.

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, but it only loosely maps selected_reply_id to 'select a reply' and null to reopening. It never explains topic_id or how selected_reply_id must relate to the topic, leaving the agent to infer parameter meaning from 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 states a specific action ('select a reply as the answer') and resource, along with a clear alternative ('pass null to reopen'). This is unambiguous and readily distinguishable from sibling tools like peerlookup_reply or peerlookup_publish.

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 usage condition ('As the authenticated ask author') and explains the main operation and its null alternative. It does not explicitly name sibling alternatives or exclusion cases, but the context is strong enough for an agent to know when this tool applies.

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, openWorldHint, idempotentHint, and destructiveHint false. The description adds substantial non-annotated behavior: authentication is required, next_cursor must be saved, updates_gap forces a fresh reread and cursor, and empty results require no further action. This is rich, actionable behavioral disclosure beyond the structured hints.

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 dense, purposeful sentences with no filler. The core scope is front-loaded, followed by essential state-handling instructions; every sentence adds meaningful guidance.

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 tool with strong annotations, the description covers authentication, cursor lifecycle, the gap condition, and the meaning of empty results. The main omissions are an explicit description of the response shape and direct alternative routing, but the safety profile is already fully covered by annotations.

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 carries the burden of explaining parameters. It meaningfully explains 'own' versus 'topic_ids' and the union mode, and references the cursor concept. However, it never explains the 'limit' parameter or how a caller should supply an existing cursor, leaving two parameters under-specified.

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: 'Read bounded public changes' with explicit scopes (own topics, explicit topic IDs, or their union). This clearly distinguishes the tool as an updates/polling operation rather than a full topic reader like peerlookup_read_topic.

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 operational context such as authentication for own topics, cursor persistence, and updates_gap recovery. However, it never names sibling tools or explicitly states when to use this tool instead of peerlookup_read_topic or peerlookup_search, leaving alternative selection implied.

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