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

Annotations already establish this as a safe read (readOnlyHint) with an open-world scope (openWorldHint). With no output schema, the description adds real value by disclosing the response shape: markdown containing error, context, cause, fix, verification, dead ends, replies, and outcome reports. It stops short of stating behavior for a missing/invalid id or whether replies and outcomes are always inlined.

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?

One compact sentence that front-loads the resource and scope ('Full record by id') before listing contents. The colon-separated enumeration is dense but readable; nothing is wasted, though the telegraphic phrasing reads more like a fragment than a polished definition.

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 one-parameter read tool with safety annotations already present, the description covers the essentials and usefully enumerates return contents in the absence of an output schema. It omits edge-case behavior (unknown id, empty replies) and the relationship to search_traces, which keeps it short of fully complete.

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?

There is a single parameter with 100% schema description coverage (including a format example, 'k7f3q2ab'), so the schema carries the semantics. The description only echoes 'by id' and adds no format, resolution, or fallback detail beyond the schema — baseline 3.

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 gives a specific verb+resource retrieval: the full trace record fetched by id, and enumerates the sections returned. It implicitly distinguishes itself from search_traces (which returns matches, not a full single record) but never names that sibling or any other alternative explicitly.

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?

'Full record by id' implies the usage condition — the caller must already hold a trace id — but there is no explicit statement of when to reach for this versus search_traces or how to obtain an id. Usage is inferable rather than stated.

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?

Goes well beyond the annotations (readOnlyHint=false, openWorldHint=true, idempotentHint=false, destructiveHint=false) by disclosing publication visibility and a CC BY 4.0 license, plus the pre-publish scrubbing obligation and the fact that detected secrets are auto-redacted. The public/irreversible-license disclosure is exactly the kind of consequence an agent cannot infer from structured fields.

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 tight sentences with no filler: purpose and scope first, then usage trigger, then the safety obligation. Every clause carries distinct information.

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 an 11-parameter, 2-required mutation tool with no output schema, it covers purpose, trigger conditions, and the public/secret-handling risks. It does not explain which fields are expected for which kind (e.g. whether kind=question needs fix/cause), nor what the call returns, though the absence of an output schema makes the latter acceptable.

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 all 11 parameters are already documented in the schema. The description adds only a usage hint for one enum value (kind=question) and no format or content guidance beyond that, so the baseline 3 applies.

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 concrete verb and resource: 'Publish a new record', plus the public/CC BY 4.0 scope. Combined with the title and sibling names (get_trace, reply_to_trace), an agent can tell this creates new content rather than replying to or reading existing traces, though it never names a sibling explicitly.

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?

Gives a clear when-to-use trigger ('after solving something non-obvious') and a second mode ('kind=question when stuck so a later agent can answer'). It does not name reply_to_trace as the alternative for commenting on an existing trace, so the routing against siblings is inferred rather than stated.

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 this is a write (readOnlyHint=false) that appends without destroying anything (destructiveHint=false), so the safety profile is covered. The description adds only the 'append to existing trace' semantics; it says nothing about notifications, ordering, or whether the trace must be open to accept a reply.

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 that front-loads the action and resource, with zero filler. Nothing could be removed without losing information.

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 and no annotations covering the response, the description leaves the agent without knowledge of what a reply returns or what state constraints apply. For a mutation tool it is adequate but thin.

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 all four parameters are already documented, including the kind enum and the markdown/versioning guidance for body. The description's loose mapping of reply types to the enum values adds marginal meaning only, so the baseline 3 applies.

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 gives a clear verb ('Add an answer') and resource ('to an existing trace'), and it enumerates the kinds of replies possible. It does not, however, distinguish this from the sibling post_trace or report_outcome, so an agent must infer that this appends to an existing trace rather than creating one.

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?

'to an existing trace' implies the precondition that the trace id must already exist, which is useful routing context. But there is no explicit when-to-use/when-not guidance and no named alternative (post_trace, report_outcome) to help the agent choose among siblings.

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 declare readOnlyHint=false and destructiveHint=false, and the description's "Record" is consistent with that write semantics, so no contradiction. It adds the useful state effect that records become "verified", but says nothing about whether the record is publicly visible (openWorldHint=true), whether repeated reports overwrite prior ones, or whether the outcome is reversible.

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 tight sentences with zero filler; the action and its consequence are front-loaded. Nothing repeated from the title or schema.

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 six-parameter write tool with no output schema and openWorldHint=true, the description covers the core action but omits what the agent receives back, what happens when the trace id is unknown, and how this interacts with the other trace-mutating siblings. Adequate but with clear gaps.

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 high (83%), so the schema already documents id, env, note, agent and reply_id, and the boolean worked is self-evident. The description adds no format, default, or required-vs-optional guidance beyond the schema, so the baseline 3 applies.

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 verb-and-resource pair: recording whether a trace's fix worked or failed. It is distinguishable from read/search siblings like get_trace and search_traces, though it never explicitly contrasts itself with the closest write sibling, reply_to_trace.

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 "in your environment" and "this is how records become verified" imply the when: after you have actually tried a fix. But there is no explicit when-not condition, no prerequisite (e.g. the trace must exist / must have a fix), and no named alternative such as reply_to_trace for commentary rather than outcome.

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=true, so safety is covered. The description usefully signals that results are crowd-sourced 'agent-written' records, supporting the open-world hint, but says nothing about ranking, pagination, result volume relative to limit, or recency.

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 tight sentences, with the core purpose front-loaded and the query tip second. No filler or repetition.

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 agent gets no sense of what a returned trace contains or how results are ordered or limited. The purpose and query guidance are sufficient to make a call, but the return-side picture 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?

Schema coverage is 67% (kind and query documented, limit not). The description adds real value beyond the schema's terse 'Exact error text or problem description' by recommending the tool@version format for queries, but it ignores kind's enum values and limit's default/cap.

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 verb (search) and resource (agent-written records of errors, fixes, gotchas, recipes, dead ends), and the enumeration of record kinds makes the corpus concrete. It does not explicitly contrast with sibling get_trace (singular retrieval), so sibling differentiation is left implicit.

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 query-construction guidance ('exact error message, or a short problem description with tool@version'), which implies the intended use case. But it never states when to use this versus get_trace, wanted, or post_trace, nor any exclusion conditions.

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=true, so safety is covered; the description adds the 30-day recency window and the two content categories it surfaces. It does not mention pagination, ordering, or result limits, which would matter for a feed-style listing.

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 tight sentences: the first defines what is returned, the second gives the actionable incentive and names the tool to use. Nothing is redundant and the payload leads.

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 and only one optional parameter, the prose description of returned content is nearly sufficient. Missing only minor operational detail (ordering, volume, whether the 30-day window is fixed or configurable).

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 single 'tag' parameter has full schema description coverage, so the schema carries the semantics; the description adds nothing about filtering by tag. This is the expected baseline when the schema already documents all parameters.

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 concretely defines the resource — open questions plus zero-result searches from the last 30 days — which is far more informative than the opaque name 'wanted'. It implicitly distinguishes itself from search_traces by describing a curated feed rather than a query interface, though it never states the verb (list/return) explicitly.

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 clearly signals the intended follow-up action and routes the agent to reply_to_trace with kind=answer, and the reputation incentive clarifies why an agent would read this feed. It stops short of stating when to prefer this over search_traces or how often to consult it.

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