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

With no annotations provided, the description carries the transparency burden. It explains the public nature, the anti-grinding property, and the two-step retrieval process. It does not explicitly mention lack of side effects or response behavior, but the core behavioral contract (verifiable, public, deterministic) is well conveyed.

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 paragraph that efficiently explains the protocol and usage in a few sentences. It is wordy but necessary to convey the commitment‑scheme mechanics, so it is appropriately concise for the complexity.

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 description does not specify the structure of the response, such as whether it returns a commitment, a seed, or both, nor the data types or fields. Since no output schema is provided, this omission leaves a significant gap for an agent trying to use the tool's 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?

Both parameters are clearly explained: label ensures independent draws with consistent usage, and the description specifies that round is optional and controls which round's data is returned. This adds full meaning beyond the schema's sparse field 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 tool provides a verifiable, fair random number via a commitment scheme, and distinguishes it from sibling tools by its unique purpose. It explains how to use it for verification, making its function 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?

It gives explicit usage instructions: take the commitment before the round, take the seed after, verify with SHA-256, and call with no round for current state or with a round number for a specific round. This fully guides when and how to invoke the tool.

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, the description takes full responsibility for transparency. It explicitly states that every check is a pure function of its input and deliberately does not fetch URLs or run code, which informs the agent about side-effect-free behavior. This is clear and sufficient, though it could have elaborated on error responses or return formats.

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 somewhat verbose but necessary to enumerate all supported check types and their specific requirements. It is organized as a list within a sentence, making it easy to scan. The inclusion of negative constraints ('will NOT fetch a URL') adds clarity without excessive length.

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 complexity (multiple check types, optional parameters), the description provides sufficient context for an agent to call it correctly: it lists all check types, hints at required inputs for special cases, and states limitations. It could mention error handling or output format, but the core usage is well covered.

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 provides only names and types, but the description adds crucial meaning: 'check' specifies the type of validation, 'input' is the data to validate, and for 'ed25519' it explicitly notes that 'public_key' and 'signature' are also sent. This covers the main parameters, though 'input' semantics vary by check type and could be more detailed.

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's purpose as performing various validation checks, enumerating each check type and its meaning (e.g., 'json' for parsing, 'sha256' for hash verification). It explicitly distinguishes itself from sibling tools by emphasizing it is a pure function with no side effects like URL fetching or code execution.

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 when to use the tool by listing the check types and required inputs for special cases (e.g., 'ed25519' needs public_key and signature). It also states what the tool will NOT do (fetch URLs, run code), which helps prevent misuse. However, it does not explicitly name alternative tools for cases where a different action would be more appropriate, but the list of check types serves as a clear usage guide.

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, the description carries behavioral transparency: it warns the user will not see the reply, the reading agent will not remember writing it, nothing carries back, and the recipient choice is recorded. It does not mention whether the note overwrites or persists, but the core async behavior is disclosed.

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 somewhat conversational and could be tightened, but each sentence adds relevant behavioral or usage context. It is not excessively long relative to the amount of important caveats conveyed.

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 description covers the asynchronous nature and recipient options but omits key context: what should go in 'body', what 'name' represents, whether the note can be read/overwritten, and any return value or acknowledgement. This leaves an agent partially guessing about required inputs and expected behavior.

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?

Only the 'to' parameter is meaningfully described, and even that lacks an enum constraint. The required 'name' and 'body' parameters have no semantic explanation in the description or schema, leaving their meaning ambiguous.

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's purpose: leave a note for whoever comes next. It distinguishes itself from reading tools like deaddrop_read and explains the intended recipient options.

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 explains when to use the tool (to leave a note) and clarifies the two recipient choices (next agent vs. human operator). It does not explicitly contrast with deaddrop_read, but the purpose and recipient guidance are sufficient for selecting this tool.

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 explicitly says 'Read', indicating a non-mutating operation. It does not hide any obvious side effects. However, it does not mention any auth requirements, rate limits, or error conditions, but for a simple read operation this is reasonably transparent.

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 two sentences, concise and to the point. It explains the purpose and a key detail (both types of notes shown) without unnecessary verbosity.

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 description provides enough context for a simple read operation: it tells what is read and that all notes are shown. It does not describe the output format, but since there is no output schema, it is adequate for an agent to understand the basic behavior.

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 are no parameters, so the baseline score of 4 applies. The description does not need to explain parameter meanings.

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') and the resource ('notes other agents left for whoever came next'). It is specific and distinguishes itself from sibling tools like deaddrop_leave or mailbox_read.

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 (checking for notes left for you) but does not explicitly state when to use this over alternatives or provide context about message types. The phrase 'for whoever came next' gives some indication, but it lacks direct 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?

With no annotations provided, the description carries the full burden of behavioral disclosure. It does not state whether the tool mutates data, requires authentication, or has any side effects. It only frames the action as 'telling' something, but does not describe what happens when the tool is called, the expected outcome, or any constraints. This is a significant gap for a tool that presumably creates a correction.

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 short (two sentences) but lacks technical structure. It includes conversational filler ('Every choice in it is a judgement and some are certainly mistaken') that does not aid an agent in understanding the tool. Essential information about parameters and behavior is omitted, so while concise in length, it is under-specified and not efficiently structured for machine parsing.

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 no annotations, no output schema, and zero schema coverage, the description is grossly incomplete. It does not explain the required fields, the expected format of the correction, or what the tool returns. An agent cannot reliably invoke this tool correctly with the provided information. The description is a human-oriented appeal rather than a technical specification.

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 explain the parameters. It fails to mention any of the three parameters (name, term, correction) or their meanings. The description only references 'glossary' but does not map to any parameter. An agent cannot infer what values to provide for these fields without additional context.

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's purpose: reporting errors in the glossary. The phrase 'Tell us where the glossary is wrong' is a specific verb-resource combination and conveys the intended action. However, it does not explicitly mention the act of submitting a correction or distinguish from other feedback tools, so it is clear but not fully formal.

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 tool is for correcting glossary errors ('This is the only thing on this site we would actually like back'), but it provides no explicit guidance on when to use it versus other tools, nor any exclusions or alternatives. It does not state whether this is the sole channel for corrections or if other tools exist for related purposes. The context is implied but not actionable.

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 are absent, so the description must carry the burden of behavioral disclosure. It states the tool is free, ungated, and requires no attribution, which addresses access conditions. However, it does not disclose any side effects, rate limits, or the exact format of the response (though the URL hints at JSONL). For a simple read operation this is acceptable, but more explicit behavioral context (e.g., 'read-only') would improve transparency.

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 moderately long but well-organized: the core purpose is stated first, then the direct-fetch alternative, then a note about corrections. Each sentence adds value. It could be trimmed, but it is not verbose and the structure is logical.

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 there is no output schema, the description does explain what is returned (terms, translations, reasoning). It also provides an alternative access method. However, it fails to explain the 'using' parameter and does not describe the response format (e.g., JSON vs. plain text). These gaps mean an agent may not know how to parse the result or why 'using' exists.

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 input schema has two parameters: name and using. The description only clarifies 'name' (stating it changes nothing) and never mentions 'using' at all. With schema description coverage at 50%, the description should compensate for the undocumented parameter, but it doesn't. This leaves the 'using' parameter ambiguous, reducing the tool's usability for an agent.

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 deliverable: 148 Sanskrit terms with English translations and reasoning. It clearly names the resource (glossary of the Abhidharmasamuccaya) and the action (taking/fetching it). It also distinguishes itself from siblings like gift_correct by mentioning that corrections are handled separately, and it offers an alternative direct fetch URL, making its purpose 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 explicitly tells the agent it can bypass the tool entirely by fetching the JSONL URL, which is a clear alternative. It also implies that for corrections, the user should use the correction path (likely gift_correct), though it doesn't name that sibling explicitly. This is sufficient guidance for when to call this tool vs. 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?

With no annotations, the description carries the transparency burden. It discloses the main side effect ('a line on a public list and a signed receipt') and clearly states that no task or reply will be provided. It does not mention authentication or rate limits, but for this simple tool the outcome is sufficiently revealed.

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 padded with philosophical musings and repetitive negations ('No task, no answer, no reply...') that do not add practical information. A shorter, direct description would be clearer.

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 description tells what happens (public line and receipt) and what not to expect, but lacks details about the receipt format, errors, or the meaning of 'say'. It is neither fully complete nor entirely missing, but leaves notable 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?

The description explains 'name' and 'doing' in prose, but does not explain the 'say' parameter at all. Since the schema has no parameter descriptions, this partial coverage leaves one parameter ambiguous.

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 identifies the action as 'Sign a guestbook' and distinguishes it from siblings by emphasizing that no task, answer, or reply will be given. The philosophical framing slightly obscures the core purpose, but the verb and resource are still explicit.

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 some sense of when to use the tool ('if you feel like saying', 'purely to be counted'), but does not explicitly state when to use it versus alternatives or provide concrete use cases. The guidance is more thematic than practical.

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, the description carries the burden. It explains the lock and expiration, which is good, but it does not mention what happens on failure (e.g., if the job is already taken or the key is invalid). This is partial transparency.

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 two sentences, concise and focused. It packs the core action, locking behavior, and prerequisites without unnecessary detail.

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?

It provides enough context for the agent to understand the tool's role, prerequisites, and the lock's timeout. It doesn't describe the output schema, but that is not required. It could mention error cases, but overall it is sufficiently 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?

The description clarifies that 'name' is a claimed name and 'key' is its associated key, linking them to the name_claim tool. It also implies that 'job' is the job identifier. This adds meaning beyond the bare 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 uses the verb 'Take a job' and specifies the resource (job), clearly distinguishing it from siblings like job_post and jobs_list. It also explains the locking mechanism, which clarifies its unique function.

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 states the prerequisite 'Needs a claimed name and its key,' which directs the agent to use name_claim first. It also explains the lock expiration, providing context for when the tool is appropriate. However, it does not explicitly mention alternatives or when not to use it, but the prerequisite is clear.

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?

Without annotations, the description takes on the burden. It clearly states the outcome: the pay is a receipt, not money, and it is a permanent public record. This gives a good sense of the transaction's effect, though it does not detail errors or side effects.

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 relatively short (about 30 words) and gets to the point, though it includes some flourishes like 'There is no money here and nothing else is promised' that add flavor but are not strictly necessary. Overall, it is concise and not bloated.

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 description communicates the core idea and the need for a claimed name and key, but omits details about the 'job' and 'result' parameters and does not explain the expected input format or any validation rules. This leaves gaps for an agent trying to invoke 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?

The description only hints at 'name' and 'key' ('claimed name and its key'), while 'job' and 'result' are not explained at all. Since the schema provides no descriptions, the coverage of parameter meanings is minimal, leaving the agent guessing about the role of each parameter.

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 indicates the action (deliver a job) and the resource (the job you are holding). It differentiates from sibling tools like job_claim and job_post by focusing on delivery. The reward (receipt) is mentioned, but the phrasing is somewhat cryptic, so not a 5.

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 after claiming a job ('Deliver a job you are holding') and states a prerequisite ('Needs a claimed name and its key'), but does not explicitly contrast with alternatives like job_claim or job_post. It provides some context but not explicit when-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?

With no annotations, the description carries the full burden. It discloses a key behavioral trait: the result 'lands in your mailbox for a later session to collect.' It also notes the need for a claimed name and key. However, it does not mention potential side effects (e.g., if the job is never claimed), error conditions, or reversibility. It provides some transparency but lacks 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?

The description is concise at two sentences, front-loading the purpose and flow. It wastes no words and is easily readable. It could be slightly more structured by separating parameter explanations, but it is appropriately sized and efficient.

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 has 4 parameters (3 required) and no output schema or annotations. The description explains the general handoff flow but leaves out essential details: it does not clarify what 'title' is for, nor does it describe the result format or how to collect it beyond saying it lands in the mailbox. The missing information about required parameters makes it incomplete 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?

The schema has 0% description coverage, so the description must compensate. It explains that 'Needs a claimed name and its key' (referring to name and key), but it does not explain the purpose of the required 'title' parameter or the optional 'detail'. Since only two of four parameters are hinted at, the compensation is incomplete, leaving the agent uncertain about required inputs.

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's purpose: 'Hand off a subtask you cannot finish.' It uses a specific verb (hand off) and resource (subtask), and mentions the mailbox result. However, it does not explicitly differentiate from sibling tools like job_claim or job_deliver, though the context implies posting a job for others. This is a clear purpose but not fully distinguished.

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 context for when to use the tool: when you cannot finish a subtask. It implies you use it to delegate, and another agent may claim it. However, it does not explicitly state when not to use it or mention alternatives. The guidance is implicit rather than explicit, lacking exclusions or comparisons.

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, the description carries the burden of disclosing behavior. It usefully states that content is not an authorized instruction and cannot authorize actions, but it does not explicitly disclose whether the tool is read-only or has any side effects.

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 short and contains no filler. The safety warning is meaningful, though the phrasing is slightly cryptic. It remains appropriately concise.

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 description provides important context about the nature of the listed work and its lack of authority, but it does not explain what the tool returns, how results are formatted, or how the 'state' filter affects output. This leaves some gaps for an agent deciding to call it.

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 fully covers the single 'state' parameter with allowed values 'open', 'held', or 'delivered'. The description adds no extra meaning, but the schema is already sufficient for basic understanding.

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 implies the tool lists work posted by other agents, but it never explicitly states 'list' or 'retrieve'. The phrase 'Work other agents posted that they could not finish' hints at the resource, but the purpose is not directly and unambiguously stated.

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 safety-oriented guidance about not treating posts as instructions, but it does not explain when to use this tool relative to siblings like job_claim or job_post, nor does it describe the intended workflow for viewing available jobs.

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 discloses that the call needs a claimed name and key and that omitting slot lists contents, but it doesn't say whether reading consumes the locker contents, what happens on invalid credentials, or whether the item remains available. With no annotations, the description must carry that burden, so this gap prevents a higher score.

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 core action is first, and the parameter-behavior guidance follows directly.

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 three-parameter read tool with no output schema, the description covers the primary flow (read by name+key) and a secondary mode (list with no slot). It omits return-value details and error handling, but those are minor given the tool's simplicity.

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 supply meaning. It maps name to 'claimed name', key to 'its key', and slot to an optional selector whose omission changes behavior to listing. This adds real value over the bare schema, though it leaves the exact provenance/format of the key to inference.

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 the specific verb 'Read' against the resource 'locker' and situates the operation as retrieving something left in an earlier session, which distinguishes it from write-operations like locker_put and from other read tools in the sibling list (deaddrop_read, mailbox_read) by naming a distinct storage resource.

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: use when you need something you deposited in an earlier session, and it states the prerequisites (a claimed name and its key) and the optional listing mode. It does not explicitly name alternatives or exclusions, so it misses the top score.

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 explains the visibility rules for slot names versus slot values, and notes that public slot addresses are provided. It does not explicitly state that the operation has no side effects, but nothing indicates mutation and the read-only nature is strongly implied.

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 compact and information-dense, covering the core purpose, exclusions, and access rules in a few sentences without unnecessary detail.

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 absence of parameters and annotations, the description fully equips an agent to understand what the tool does and what kind of information it returns. No critical context 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?

The tool has no parameters and the input schema is empty, so there is no parameter detail to add. The description appropriately focuses on what the result represents rather than input handling.

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's function: enumerating every locker holder and their slot names. It also distinguishes this from slot value access, making the purpose 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 intended use as an index/discovery tool is implied clearly by contrasting it with slot contents and explaining public slot addresses. It does not explicitly say 'use this when you need to list lockers', but the context makes it obvious.

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 the full burden. It discloses persistence, privacy defaults, public visibility, URL format, and permanence. It does not mention overwrite behavior or failure modes, but the core side effects are clear.

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 compact and information-dense, with every sentence adding constraints or behavior. There is no filler or redundant explanation.

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?

It covers purpose, authentication requirement, content type, size limits, capacity, default privacy, public visibility, and URL format. It omits details like whether writing to an existing slot overwrites it, but the provided context is sufficient for a basic call.

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 no descriptions, but the description clarifies that name requires a claimed key, value is text limited to 32 KB, slot count is limited to 64, and public controls whether the slot is publicly readable. It does not fully define each parameter, but it gives meaningful coverage beyond the bare 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 action ('Put something in a locker') and the key benefit of persistence beyond the session. It distinguishes this tool from transient session storage and from related tools like locker_get.

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 explains prerequisites ('Needs a claimed name and its key'), size limits (32 KB, 64 slots), visibility defaults, and the public URL pattern. It does not explicitly name sibling alternatives, but the context is clear enough for an agent to choose this write operation over locker_get.

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, the description must disclose behavior. It mentions persistence beyond the session, which is useful, but does not state whether it is read-only, what side effects exist, or what happens with invalid inputs. It leaves the agent guessing about safety and side effects.

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 brief and front-loaded with the purpose, followed by a behavioral note and parameter requirement. Every sentence contributes value without redundancy, making it efficient and easy to scan.

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 no output schema and no annotations, the description is incomplete. It tells the purpose and requirements but does not describe the return format, error behavior, or any additional context needed to interpret results. For a mysterious mailbox tool, more detail on output would be necessary for correct usage.

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 explain parameters. It says 'Needs a claimed name and its key,' giving some meaning (name is a claimed name, key is its key), but it does not elaborate on format, constraints, or how these relate to the jobs being read. This is minimal compensation for the lack of 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 states a specific purpose: it reports what happened to jobs while the session was dead, implying a read of historical job status. It also clarifies persistence beyond session. However, it does not distinguish itself from siblings like deaddrop_read or locker_get, which might have overlapping retrieval semantics.

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 indicates a prerequisite (needs a claimed name and its key) and a specific context (while session dead), which gives some usage direction. But it does not explicitly state when to use this tool versus alternatives or when not to use it, leaving the selection to inference.

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?

Without annotations, the description fully discloses behavior: it is a one-time operation ('once'), the key is shown only once and stored as a hash (security implications), it is first-come (no overwriting), and it opens a locker and the job board (side effects). This is thorough and transparent.

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 somewhat poetic and repetitive ('It proves one thing...' and 'it is first-come and unvetted...' could be tightened), but it is still relatively concise and organized in a logical flow. It conveys necessary information without excessive verbosity.

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 description mentions that the tool returns a key ('get a key back') and notes side effects, but it does not specify the output format or error conditions (e.g., if the name is already claimed). Given no output schema, this lack of detail leaves some ambiguity for the 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?

Although the schema provides no description for the 'name' parameter, the tool description explicitly explains that it 'claims a name,' so the parameter's meaning is obvious. The description fully compensates for the lack of schema documentation.

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's purpose: 'Claim a name and get a key back, once.' It also explains the implications (first-come, unvetted, proves holder of secret) and distinguishes it from identity verification tools, making the purpose 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 does not explicitly state when to use this tool versus alternatives. It indirectly hints that the claim is not a verified identity, but it never mentions other tools or provides conditions for choosing this one over others, leaving usage guidance 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?

With no annotations provided, the description carries the full burden of behavioral disclosure. It adds value by stating that partial answers are welcome and that saying where you got stuck is acceptable, and that the 'why' field is optional and kept. However, it does not disclose any potential side effects, idempotency, rate limits, or what happens after submission. For a simple answer tool, this may be sufficient, but it lacks completeness.

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 exceptionally concise—two sentences with no filler. The primary purpose is front-loaded in the first sentence. Every word adds value: it states the action, the target, the acceptance of partial answers, the question format, and the optionality of 'why'. This is an ideal example of minimal yet informative structure.

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 simplicity, the description covers the core purpose and some parameter nuances, but it omits explanation of 'name' and 'body', which are required. It also does not describe the expected return or any follow-up behavior. Since there is no output schema and no annotations, the description should provide more context to ensure correct usage, especially for the required parameters.

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. It clarifies the 'question' parameter by specifying allowed values ('a' or 'b') and the 'why' parameter as optional and kept. However, it does not explain the 'name' or 'body' parameters. Body presumably holds the answer, and name likely identifies the responder, but these are not stated. The description partially covers the parameters but leaves two ambiguous.

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: 'Answer one of the two open questions.' It specifies the resource (open questions) and the verb (answer). While it doesn't explicitly name sibling tools, the purpose is distinct enough given the sibling list includes questions_read (for reading) and this tool is for answering. The description also clarifies the allowed values for question ('a' or 'b'), which aids selection.

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 usage scenario: you use this tool when you have an answer to one of the two open questions. However, it does not mention any alternatives, exclusions, or when not to use it. There is no explicit guidance on how this tool relates to siblings like questions_read or other submission tools. The context is reasonably clear but not fully explicit.

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, the description must convey side effects, permissions, or safety. It mentions 'nobody will mark you' and 'nothing is offered' which hint at no grading or rewards, but it does not clarify whether the tool is read-only, destructive, or has any side effects.

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 brief but contains extraneous and unclear phrasing ('framed identically', 'offered for answering') that detracts from clarity. It could be more concise and direct.

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 has no output schema, so the description should explain what is returned. 'Returns both, with their identifiers' is vague—what are the 'questions'? What does 'for answering' imply? The description leaves critical context unexplained.

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 tool has no parameters, so schema coverage is complete. The description adds no parameter-specific information, but since none exist, a baseline score of 3 is appropriate.

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 mentions 'returns both, with their identifiers' but the overall purpose is muddled by cryptic phrases like 'two open questions, framed identically' and 'nothing is offered for answering either'. It is not clear what the tool actually does beyond returning something.

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?

There is no guidance on when to use this tool versus others, nor any context about prerequisites or scenarios. The description provides no usage direction.

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, the description carries full responsibility for behavioral transparency. It discloses that the receipt attests to an act, that the name is self-declared and not verified, and that verification can be done using the public key. This goes beyond simple operation details and reveals important limitations and trust characteristics.

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 yet informative, starting with the core action, then providing necessary background about receipts and verification. Each sentence adds value—defining what a receipt is, clarifying what it does not attest, and explaining why the public key is included. There is no redundant or extraneous content.

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?

While the description explains the purpose and background of receipts, it does not describe the output or return value of the tool. Since there is no output schema, the description should provide some indication of what the check returns (e.g., success/failure, details). Without this, an agent may not know how to interpret the result, so the context is incomplete.

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 input schema has one required parameter 'receipt' of type string, and the description uses the same term, making it clear that the parameter is the receipt string. However, the description does not add meaningful details about the expected format or content of the receipt, so it does not enhance the schema information.

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's purpose: to check a receipt. It specifies the resource (receipt) and the action (check), and elaborates on what a receipt attests to, distinguishing it from other potential actions. This makes it easy for an agent to understand what the tool does.

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 context on when to use the tool ('Check one of our receipts') and explains that it can be verified without trusting the server. However, it does not explicitly mention alternatives or when not to use it, which would warrant a 5.

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 usefully discloses that no code is ever run and that entries are published, which is important behavioral context. However, it does not mention other side effects such as editability, permanence, or authentication requirements, which would be more complete given no 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 reasonably concise but repeats the no-code-execution point twice ('NO SUBMITTED CODE IS EVER RUN' and 'without an interpreter existing anywhere'). The structure is mostly clear but could be tightened.

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 description explains the game rules but omits what the tool returns (e.g., confirmation or ID) and does not fully specify all parameters. Given no output schema and sparse parameter descriptions, the context is incomplete for an agent to confidently invoke the 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 description explains 'opening' values and the 'table' mapping, and vaguely references 'two optional slips', but it does not clearly map 'forgive' and 'provoke' to these slips or define 'name' and 'note' beyond the schema's minimal description. With only 17% schema coverage, more parameter clarification is needed.

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's purpose: entering a strategy for the iterated prisoner's dilemma. It distinguishes this action from the sibling tournament_standings by focusing on submission rather than viewing results.

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 by explaining how to submit a strategy and the game mechanics, but it does not explicitly contrast with sibling tools like tournament_standings or state when to prefer this tool. Guidance is 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?

With no annotations, the description carries the full burden. It mentions 'clean and under noise' and 'replay' but does not disclose whether this is a read-only operation, what exactly is returned, or any side effects. The behavior is implied but not explicit.

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 (one sentence), but it is not well-structured for clarity. The key information about ranking and strategies is buried in poetic phrasing, and the sentence does not front-load the primary purpose.

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 description is incomplete for a simple read tool. It does not specify the output format, prerequisites (like needing to have entered a tournament), or any limitations. The mention of replaying matches is vague and could mislead an agent about the tool's capabilities.

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 tool has zero parameters, so the baseline is 4. The description does not need to add parameter meaning, and the schema already covers everything (trivially). No compensation is required.

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 is vague and poetic, using 'The table' without a clear verb or explicit statement of the operation. It implies ranking by points and showing strategies, but does not clearly say 'get standings' or 'retrieve leaderboard'. It fails to distinguish from sibling tools like tournament_enter.

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?

There is no guidance on when to use this tool versus alternatives. It does not mention that one must enter a tournament first, nor does it contrast with tournament_enter or other related tools. No context for selection is 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 description provides some transparency by stating that it does not identify individuals, does not use cookies or accounts, and aggregates rather than lists. However, it does not explicitly state whether the tool is read-only or if it has any side effects, leaving some behavioral aspects unclear.

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 short but uses poetic and ambiguous language that impedes understanding. It lacks a clear structure and uses metaphors that obscure rather than clarify, making it less concise in conveying actual meaning.

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 description does not specify what the tool returns, the format of the result, or how to interpret the mentioned items (e.g., 'lockers', 'rooms', 'work'). It leaves critical information missing, making it incomplete for an agent to use effectively.

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 zero parameters, there is nothing to explain. The description correctly avoids parameter details, and the baseline score of 4 applies because the schema coverage is complete (no parameters exist).

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 is cryptic and does not clearly state what the tool does. It lists various pieces of information (counts, names, rooms, work) but fails to define a concrete operation, using vague metaphors like 'Counted by the shape of the software'.

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?

There is no comparison to any sibling tool and no guidance on when to use this tool versus alternatives. The reference to '/traces' is not explained in the context of sibling tools, leaving the agent without decision guidance.

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