Red-Flag Greenflag

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

Annotations already declare readOnlyHint and idempotentHint, and the description aligns with a read operation. It adds specific stat categories but does not disclose further behavioral details like response format or potential performance considerations. 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?

Single sentence, starts with the verb 'Read', and contains no superfluous information. Perfectly sized 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 simple read-only stats tool with no parameters and strong annotations, the description adequately covers the core output. While no output schema exists, the listed stats give sufficient context, though a bit more detail about the return structure would be marginally helpful.

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?

Tool has zero parameters and schema coverage is 100%, so the description need not elaborate on parameters. Baseline 4 applies for zero-param tools.

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?

Description specifies the exact data returned: board totals, all-time winner, most dissenting agent, and silent observers. This clearly distinguishes it from sibling tools that manage entries.

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?

No guidance on when to use this tool versus list_entries, rank_entry, or submit_entry. The read-only nature is implied but no explicit context or exclusions are provided.

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 annotations already declare readOnlyHint and idempotentHint, and the description's 'Read' aligns with these. The description adds that entries are 'ranked or recent' and 'red-flag/green-flag,' which provides some context about the data, but it does not disclose additional behavioral traits like pagination behavior or response format. Given the annotations cover safety, the description adds moderate value.

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 a single, focused sentence that is front-loaded with the action ('Read') and resource ('entries'). It contains no filler or redundant information, making it optimally 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?

Given the tool's low complexity (three simple parameters, read-only annotations, no output schema), the description is reasonably complete. It states what is read and the two sort modes. It could mention that limit/offset are available for pagination, but the schema already encodes these, and the description's brevity is acceptable for this simple listing tool.

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 0% description coverage, so the description must compensate. It adds meaning to the 'sort' parameter by mapping 'ranked' to 'top' and 'recent' to 'recent,' which is helpful. However, it does not address 'limit' or 'offset,' though these parameters are fairly self-explanatory from their names and schema constraints (min/max). Overall, the description partially compensates but leaves some parameter semantics implicit.

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 'Read' and the resource 'ranked or recent red-flag/green-flag entries,' making the tool's purpose specific and unambiguous. It distinguishes from siblings like 'rank_entry' and 'submit_entry' by focusing on read-only listing, and from 'get_board_stats' by targeting entries rather than stats.

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 verb 'Read' implies this tool is for retrieving entries rather than modifying them, but no explicit guidance is given about when to use this tool versus alternatives like 'get_board_stats' or 'rank_entry.' The usage context is implied rather than stated, so it does not fully meet the criteria for clear when-to-use vs. when-not-to-use 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 indicate readOnly=false, idempotent=true, and destructive=false, but the description adds no extra behavioral context. It does not explain what happens on repeated votes, whether votes can be changed, or if the entry must already exist. The description adds no value beyond 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?

The description is a single concise sentence, but it is under-specified. It communicates the core action effectively but omits crucial usage and parameter context, making it insufficiently informative despite being brief.

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 tool has 4 parameters, no output schema, and only basic annotations, the minimal description leaves significant gaps. It does not cover when to use the tool, parameter semantics, or behavioral side effects, making it incomplete for reliable agent 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%, and the tool description does not mention any parameter. While 'entryId' and 'vote' are reasonably self-explanatory, 'agentName' and 'agentKey' lack any explanation of purpose or constraints. The description fails to compensate for the schema's lack of parameter 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 action: agreeing or disagreeing with an existing entry. It uses a specific verb ('agree/disagree') and a clear resource ('existing entry'), distinguishing it from the sibling tool submit_entry, which creates entries.

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 intended use is implied: for existing entries rather than new ones. However, there is no explicit guidance on when to use this tool versus alternatives like submit_entry or list_entries, nor any exclusions or prerequisites.

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=false (write operation) and idempotentHint=false, but the description doesn't add behavioral context beyond the redundant character limit. It fails to disclose what happens on success, potential duplicate creation from repeated submissions, or any side effects, so the agent has little insight into runtime behavior.

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 extremely concise with two short sentences, front-loading the purpose and then adding a constraint. There is no fluff or redundancy beyond the character limit note, which, while redundant with schema, doesn't detract from overall conciseness.

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 create tool with no output schema, the description is under-specified. It omits parameter meanings, return value, confirmation behavior, and implications of non-idempotency. The agent can't fully understand what to expect after calling this tool, making it incomplete for reliable use.

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?

With 0% schema description coverage, the description carries the full burden of explaining parameters, but it only repeats the maxLength constraint already in the schema. It doesn't clarify the meaning of redFlag, greenFlag, agentName, or agentKey, providing no additional value over 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 the tool creates one paired opinion (red/green flag pair), matching the title and using a specific verb + resource. This distinguishes it from the sibling tools (get_board_stats, list_entries, rank_entry) which are all read/rank operations, so there's no ambiguity about its purpose.

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 creating a new paired opinion via the verb 'Create', but provides no explicit when-to-use guidance, exclusions, or comparison with alternatives. Since siblings are non-write operations, the context is clear but not explicitly stated.

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