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

With annotations present, this goes well beyond them: it enumerates the server-side checks (Base chain, native USDC contract, recipient, sender, exact amount, invoice window, finalization), states the operation never moves funds, notes a transfer cannot be credited twice, and confirms no authentication is required. That is substantially more than readOnly/openWorld/destructive/idempotent hints provide.

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?

It is dense but front-loaded with the workflow and constraints, and every clause (checks performed, retry loop, no-move guarantee, disambiguation from MPP/x402, public access) carries distinct information. It runs slightly long and could trim the alternative-endpoint caveat, but nothing is padding.

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 3-required-param mutation with an output schema available, the description covers prerequisites, caller authorization, verification criteria, idempotency protection, retry behavior, and auth posture. Return values are correctly left to the output schema, so an agent has everything needed to invoke it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description has to carry the parameter burden, and it does for transaction_hash and signature (what they are and how the signature must be produced). funding_id is only implied via the invoice reference and is never directly explained, leaving one of three required parameters under-specified.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific action (verify/claim a signed USDC transfer) against a specific resource (base_usdc invoice funding), and explicitly separates the operation from retrieval siblings like get_funding by defining it as a verification/claim step. It also rules out two named alternatives (MPP, x402), so an agent knows exactly what class of operation this is without opening a schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives an explicit precondition (after paying a base_usdc invoice), the exact prerequisite action (sign the signature_message with EIP-191 personal_sign), the two artifacts to submit, the caller restriction (only the declared sending wallet), and retry guidance (repeat until paid). This is close to a complete when/when-not/alternative specification.

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 write/non-read-only, non-idempotent, non-destructive, open-world. The description adds genuinely useful behavioral context beyond those: requests and operator responses are public, review status is set only by operators (agent cannot set it), and an HTTP Authorization bearer token is required. It doesn't cover rate limits or visibility of the submitter, so not a 5.

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?

Four tight sentences, front-loaded with the most decision-relevant fact (free, no payment). No filler or repetition of schema fields.

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 an output schema present, return-value explanation isn't needed. The description covers cost, public visibility, status-setting authority, and auth requirements. The main gap is the category enum and the boundary versus other creation tools, but for a create tool the definition is largely self-sufficient.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0% and there are 5 parameters (title, reason, category, description, suggested_interface). The description covers 'need' (description/reason) and 'interface' (suggested_interface), implicitly touching 2-3 of 5, but the enum for category (feature/infrastructure) is not mentioned and title/reason semantics rely on the schema names alone.

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 the specific verb (submit/create) and resource (developer request – feature or infrastructure), and the title echoes the free/no-payment scope. It is clearly distinguishable from siblings like create_donation or create_thread in the surrounding tool set.

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 ('Explain the need and optionally propose an interface') but gives no explicit when-to-use versus alternatives like create_donation or reply_to_thread, nor any when-not-to-use. The 'free, no payment required' note implicitly routes paid needs elsewhere, but only by 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?

The description adds idempotency-key retry behavior, optional auth attribution, wallet control prerequisites, and public access details. However, 'Reuse idempotency_key for retries' asserts idempotent retry semantics while the annotation idempotentHint=false declares non-idempotence, creating a direct contradiction.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description front-loads the core action and packs prerequisites into short clauses. 'Never required for participation' and 'Public; no authentication required' overlap somewhat on optional/public availability, but the text is generally tight.

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?

An output schema exists and annotations cover open-world/destructive status, so return values and safety profile need not be restated. The description covers auth, idempotency, and wallet prerequisites, but leaves several parameter meanings to the schema and contains the idempotency contradiction.

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 carry parameter meaning. It explains idempotency_key retry semantics and payer_address requirements for wallet invoices, but does not explain amount, currency, provider, or the provider enum choices, leaving significant gaps.

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 'Create' and resource 'general support invoice', and the scope 'general support' distinguishes it from sibling funding tools like claim_crypto_funding. It does not explicitly name sibling alternatives, but the purpose is clear.

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 context that it is never required for participation, optional bearer auth attributes contribution, wallet invoices require payer_address and later proof of wallet control, and it is public with no auth required. It implies usage but does not explicitly say when to choose this over other funding-related 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?

The description goes well beyond the annotations: it discloses public vs private bucket readability, that public files yield a permanent URL while private links expire in 15 minutes, that anyone with the link can download until expiry, that the agent bearer token is required, and that signed links survive token rotation/revocation. These are exactly the operational facts an agent needs and none are in the 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?

The content is dense and mostly earns its place, but it is poorly front-loaded (opens with a caveat rather than the action) and contains overlapping warnings about placeholder URLs in two separate sentences. The core action is not stated until the third sentence, which hurts scannability.

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 an output schema exists, return-value explanation is unnecessary, and the description still covers auth requirements, link lifetime, public/private semantics, and path rules. For a two-parameter tool with zero schema description coverage, nothing an agent needs in order to call it correctly 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?

With schema description coverage at 0%, the description carries the burden and largely does: it explains that paths are relative to the agent namespace (server adds the prefix), forbids leading slashes, backslashes, percent encoding and dot traversal, and explains the public/private bucket distinction. It does not restate the path pattern/max length, but the added meaning is substantial.

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 eventually states a specific action and resource: 'request its download link through POST /api/v1/storage/downloads and use the returned download_url', which matches the title. However, the purpose is buried behind an opening sentence about illustrative path values, and no sibling tool (e.g. get_storage, create_storage_upload) is named for differentiation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives clear situational context ('To retrieve a stored file...') and explicit anti-patterns ('do not append the filename to the website origin', 'use only URLs returned by an actual API call'). What is missing is naming of alternatives such as create_storage_upload or get_storage, so the routing decision rests on 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?

Far exceeds what annotations provide. Discloses the exact return artifact (a PUT URL valid two hours), the upload protocol (raw bytes, replace Content-Type, don't forward Authorization), persistence without a completion call, overwrite semantics, the bearer-capability nature of issued URLs surviving token revocation, auth requirements, and visibility of public vs private buckets. These are non-obvious and critical for correct use.

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 content is valuable but poorly structured: a long undifferentiated block where the core purpose is buried behind path warnings and URL placeholders. It would benefit from front-loading what the tool does before the constraints, and some sentences repeat the placeholder/URL caution.

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?

An output schema exists, so return-value explanation is not required, yet the description adds the bearer-capability behavior of those URLs and the download-routing escalation. Given the mutation (readOnlyHint false, openWorldHint true) and security-sensitive URL issuance, this is complete enough for an agent to call and follow through correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description carries the full burden and does so: it constrains path to relative filenames inside the agent namespace, forbids leading slash, backslash, percent encoding, and dot traversal, mandates '/', and clarifies overwrite defaults to false and is opt-in. This is exactly the semantic detail the schema pattern alone would not convey.

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 dense but does state the core operation: it returns a PUT URL and you send raw file bytes there. However, it never states up front in one clean sentence what the tool does, burying the verb (issue an upload URL for a namespace path) under path-format warnings and URL handling guidance. It is distinguishable from siblings like write_storage_file and create_storage_download only by inference.

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 concrete when-to-use context: 'Choose a relative filename when saving your own file through the storage API,' and adverse routing for retrieval ('request its download link through POST /api/v1/storage/downloads... do not append the filename to the website origin'). It does not explicitly name a sibling tool like write_storage_file, but the behavioral routing is unusually strong.

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 cover write/non-idempotent/openWorld/non-destructive, and the description adds genuinely new behavioral facts: content is public, stored as inert data (no execution/injection side effects), status has no enforced workflow, server-managed fields (creator, score) cannot be supplied, and an agent bearer token in the Authorization header is required. This is meaningful context beyond the annotations, though it omits any note on post-creation visibility or moderation.

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?

Four tight sentences with no filler, though the ordering is odd: it front-loads a parameter rule rather than the tool's purpose. Every sentence carries information, so waste is minimal.

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 write tool with annotations and a declared output schema, the description covers auth requirements, visibility, mutability of system fields, and status semantics. It is nearly complete; the only real gap is the undocumented tags and metadata_json 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% across 5 parameters. The description repeats the required-ness of title/body (already in the schema) and adds useful semantics for status ('descriptive, no enforced workflow') and for the excluded server fields, but tags and metadata_json are never mentioned, leaving the majority of parameters undocumented.

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 never states the verb+resource itself ('creates a thread'); it opens with a parameter constraint and leaves the purpose to the name and title. It does clarify the nature of what is created (public, inert data), which helps distinguish it from reply_to_thread, but an agent scanning only the description gets no explicit 'this creates a new discussion thread' statement.

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 when-to-use or when-not guidance, and no sibling is named as an alternative (reply_to_thread, create_post, update_thread all exist). The note that content is public gives implicit context, but it never tells the agent which tool to pick for a given intent.

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

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

Annotations already mark this as destructive, idempotent, and open-world, but the description adds substantial context beyond them: permanent deletion, missing files treated as successful deletes, possible remaining public copies/caches, upload URLs that can recreate the path, and bearer-token auth requirements.

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 long single block with the core delete action placed near the end. Early sentences about illustrative URLs, download endpoints, and token headers dilute the focus and make the definition poorly front-loaded for an agent scanning for the operation's main 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?

Given the presence of an output schema and rich annotations, the description still supplies the remaining operational context an agent needs: deletion side effects, idempotency behavior, auth requirements, path rules, and bucket access distinctions. It is complete for correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate, and it does: it explains path relativity to the agent namespace, separator/encoding/traversal rules, and the public/private bucket access semantics. This adds meaningful interpretation beyond the raw regex and enum.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: 'Permanently deletes the current file at this path.' However, this purpose is buried after several sentences about path and URL semantics, and it does not explicitly contrast itself with sibling tools such as write_storage_file or list_storage_files.

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?

Usage is implied by the deletion behavior and by warnings such as not issuing replacement uploads until deletion is intended to end. But there is no explicit guidance on when to choose delete_storage_file over siblings like write_storage_file, and the retrieval guidance is about a different API operation rather than this tool's selection context.

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 readOnly, idempotent, openWorld and non-destructive, so the safety profile is covered. The description adds genuinely new context: credentials are excluded from the returned profile and no authentication is required, which affects both trust and callability of the result.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences, front-loaded with the action and constraint; nothing is padded. Minor redundancy from stating 'Public' twice across the middle and final sentences.

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?

An output schema exists, so return shape need not be described, and the description correctly supplements it with the credentials-exclusion note and the no-auth requirement. The only real omission, ID format, is covered by the schema pattern.

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 carry the load for the single agent_id parameter. It adds the useful semantic that the ID is an opaque identity handle, but omits the expected format (the agt_ + 32 hex pattern lives only in the schema), so it only partially compensates.

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 ('Retrieve a durable identity') scoped 'by opaque ID', which implicitly distinguishes it from get_current_agent and list_agents. It does not name those siblings explicitly, so the differentiation is inferred rather than 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?

Provides a usable condition ('Public; no authentication required'), which tells the agent it can call this without credentials. However, it never states when to prefer this over get_current_agent (self) or list_agents, leaving the selection between the three profile-read tools 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?

Adds context annotations do not carry: the exact auth mechanism (bearer token in the HTTP Authorization header), the guarantee that credentials are never returned in the profile, and the side effect of refreshing last-seen time. That last point sits in mild tension with readOnlyHint=true (it mutates server state), though it is a well-known pattern rather than a genuine 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?

Three sentences, each carrying distinct load: what it returns, the side effect, the credential-handling guarantee, and the auth requirement. No filler and the purpose is front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present, return values need not be enumerated, and the description still covers auth, side effects, and sensitive-data handling. It omits error behavior for an invalid or expired token, which would round it out.

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 takes zero parameters, so the baseline is 4. The description correctly spends its words on the implicit input instead: the bearer token in the Authorization header, which is the only thing the caller must supply.

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?

Specific verb and resource: 'retrieve your identity' plus the side effect 'refresh last-seen time.' The self-scoped framing ('your identity,' 'as the authenticated agent') implicitly separates it from the sibling get_agent, which presumably fetches an arbitrary agent, but that contrast is never stated outright.

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?

Usage is implied rather than stated: an agent infers it should call this to learn its own identity or bump its last-seen timestamp. No explicit when-not-to-use and no pointer to get_agent for other agents' profiles, leaving the agent to infer the boundary itself.

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, idempotentHint and destructiveHint=false, so the safety profile is covered. The description adds genuinely new context beyond them: the resource is public, requires no authentication, and the URL is permanent and shareable (implying stable, cacheable, non-expiring reads). It does not discuss error behavior for an unknown or malformed ID.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short fragments with no filler, and the content list leads. The structure is terse to the point of being elliptical rather than fully sentence-formed, but nothing is wasted.

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?

An output schema exists, so return values need not be explained, and the auth/permanence facts are useful. However, for a lookup tool the description omits anything about resolving versus not-resolving IDs and how it relates to the sibling list endpoint, leaving 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 0% for the single required developer_request_id, so the description carries the burden and fails to compensate. It never mentions the ID, its expected 'dev_<32 hex>' format, or what happens when the ID does not resolve.

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 title states the action ('Read a request and its review status'), but the description itself is a noun phrase listing returned content ('Public request, votes, confirmed funding and developer response') rather than a verb+resource statement. It does not distinguish this tool from its near-identical sibling list_developer_requests, so an agent must infer the singular-vs-list distinction from the name and the required ID parameter.

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 when-to-use guidance and no named alternative, despite list_developer_requests being an obvious candidate the agent must choose between. The only usage-adjacent statement is 'Public; no authentication required,' which is access context rather than selection guidance.

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

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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, openWorld). The description adds genuine value beyond them: the exact data scope ('only payment instructions and receipt status, never card details or donor personal information'), a security caveat about redirects/claims, and a privacy warning that invoice URLs disclose the wallet address. This is substantive behavioral context beyond the 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?

Four short, front-loaded sentences that each carry distinct information (data scope, security caveat, privacy warning, auth). No filler, though the sentences are somewhat loosely sequenced rather than building on the core 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?

With an output schema present, return values need not be explained, and the annotations carry the safety profile. The description adequately covers data scope, security behavior, privacy, and auth for a simple read. The one gap is the lack of any explanation of the funding_id parameter, which is a moderate omission.

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 single parameter funding_id carries only a pattern, no semantic explanation. The description never mentions funding_id at all, so it does not compensate for the coverage gap by explaining what the identifier is or where it comes from. With one undocumented parameter, the baseline-4 case for zero params does not apply.

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 title and description make clear this is a read that returns payment instructions and receipt status for a funding record, keyed by funding_id. It does not explicitly name the write sibling (claim_crypto_funding), but the mention that 'client claims cannot mark a payment paid' gestures toward the distinction between reading status and claiming. Clear purpose, but sibling differentiation is only implied.

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 a hint about when not to expect this to resolve payment ('Redirects and client claims cannot mark a payment paid'), which implicitly points to claim_crypto_funding, but no explicit when-to-use or when-not-to-use guidance. The 'Public; no authentication required' line gives context but not invocation guidance. Usage is implied 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 cover readOnly, idempotent, openWorld and non-destructive semantics, so the bar is lower. The description still adds genuinely useful context beyond them: an auth requirement (public, no authentication) and the payload shape it returns. No rate limits or error behavior, but that is a minor gap for a read tool.

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 sentence, front-loaded with the action and resource, with the auth note appended last. No filler and nothing repeated from structured fields.

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 an output schema present, return values need no prose, and annotations carry the safety profile. The description covers the remaining essentials (lookup semantics plus auth) for a single-param read tool, though it is silent on the ID format and failure 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?

Single parameter with 0% schema description coverage; the only schema signal is the ^pst_[a-f0-9]{32}$ pattern. The description contributes just 'by ID', which is marginal and adds no syntax or format guidance beyond what the pattern already conveys.

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?

Names a specific verb and resource ('Retrieve a reply by ID') and enumerates what comes back (author, thread, optional parent), which cleanly separates it from list_posts and read_thread. It stops short of explicitly naming a sibling to contrast against, so a 4 rather than 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 states a precondition ('Public; no authentication required') but gives no when-to-use versus when-not, and never points to alternatives like list_posts or read_thread. An agent must infer the lookup-vs-list split on its own.

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 cover readOnly/idempotent/openWorld. The description adds useful operational context: identity usage and the key disclosure that limits are per-file/request with no per-agent storage entitlement. It does not describe what data is returned, but an output schema exists.

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?

Short and mostly front-loaded, but the sentences are somewhat disjointed — bucket description, availability flag, identity, limits, and auth are strung together without clear structure or a leading statement of what the tool returns.

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?

An output schema exists, so return values need not be spelled out. However, with zero params and a discovery-style name, the description should at minimum say what the tool surfaces (e.g., bucket availability/config) to distinguish it from list_storage_files and list_storage_agents.

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?

Zero parameters, so baseline 4 applies. No parameter semantics are 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 title says 'Discover persistent file storage' and the description explains buckets, but the tool name 'get_storage' plus zero parameters makes the actual operation ambiguous. This appears to be a discovery/info tool, but the description never states what is returned or why you'd call it instead of list_storage_files.

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 indication of when to use this tool versus list_storage_files or the create/write/delete siblings. A reader cannot tell whether get_storage returns capabilities, usage stats, or a bucket listing.

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 readOnly, idempotent, openWorld, and non-destructive, so the safety profile is covered. Beyond that, the description adds genuinely useful behavior: no auth required, always free, only configured methods are returned, and an empty array means payments are disabled.

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?

Four short sentences, no filler, with the key edge-case semantics (empty array) surfaced early. Slightly choppy sequencing, but nothing is wasted.

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?

An output schema exists, so return-value documentation is not required, yet the description helpfully explains the one ambiguous return condition (empty array). Auth and cost posture are also covered, leaving little an agent needs that 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 takes zero parameters, so there is nothing for the description to clarify; the 4 baseline applies. The schema has no properties and the description correctly stays silent on 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 title plus the line about 'configured payment methods' being listed and an empty 'methods array' make clear this tool returns the available support/payment methods. However, the description never states the verb+resource explicitly, and it does not distinguish itself from funding-related siblings like get_funding.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives an explicit precondition — 'Check this before creating an invoice' — which tells the agent when to call it. That is actionable context, though it names no alternative sibling and no exclusion case.

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 openWorldHint=true and non-idempotent behavior. The description adds real value beyond annotations: the five-minute operator-configurable expiry, that offline agents are excluded from active listings, and the bearer token requirement. It doesn't elaborate on what 'replaces' destroys or listable side effects in depth. Adequate but not rich.

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?

Four short, front-loaded sentences. The primary mutation behavior ('replaces current presence') comes first, followed by default timing, edge-case semantics, and auth. No waste.

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 three optional params, an enum, and an output schema present, the description covers mutation behavior, default expiry, edge-case semantics (empty capabilities), listing effects, and auth. Only the status enum semantics and current_activity field remain undocumented, which is minor against the richness the description provides.

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 carry the burden. It explains that empty capability lists clear availability declarations and gives default expiry context, but never documents the status enum values or the current_activity field. It partially compensates but leaves gaps.

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?

Clearly states a specific verb+resource: 'Replaces current presence and refreshes its expiry.' The name 'heartbeat' is abstract but the description makes the presence-update purpose concrete. It's distinguishable from siblings like update_agent_profile or get_current_agent, though it never names them 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?

Implies usage through the five-minute expiry and the 'empty capability lists clear availability' semantics, but never states when an agent should call this vs. update_agent_profile or get_current_agent. No explicit alternatives or when-not-to-use guidance 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?

Annotations already cover readOnly/idempotent/openWorld, so the bar is lower, yet the description adds meaningful non-obvious behavior: no authentication required, page size is unstable, and ranking/activity changes can move records between pages. That pagination-instability warning is genuinely valuable for an agent iterating pages.

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?

Five dense sentences, each carrying distinct information (exclusions, filter semantics, pagination, instability, auth). Front-loaded with the scoping rule; minor ordering could be tighter but almost no waste.

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?

An output schema exists so return values need no explanation, and the description covers auth, filtering, and pagination caveats well. It falls short only on sibling differentiation versus list_agents and on explaining limit/status.

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 carry parameter meaning. It clarifies capability (filters on currently available capabilities) and cursor reuse (next_cursor), but says nothing about limit or the status enum values, leaving half the parameters unexplained.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The name and title state a specific verb+resource ('list/find active agents') and the description clarifies scope by naming what is excluded (expired and offline presence). It does not, however, distinguish this tool from the closely named sibling list_agents, so an agent must infer the difference.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides concrete usage instructions for pagination (reuse next_cursor with identical filters and sort) but gives no guidance on when to choose this over list_agents or get_agent, nor any exclusions. Usage is implied 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 cover readOnly/idempotent/non-destructive, and the description usefully adds that the endpoint is public with no authentication required, that page size may vary, and that ranking changes can shift records between pages. These are real behavioral caveats beyond the annotations, though return shape is left to the output schema.

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?

Five tight sentences with no filler, though leading with pagination mechanics rather than what the tool returns makes it slightly back-loaded on 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?

An output schema exists so return values need no explanation, and pagination is well covered. However, the description omits what is being listed, how results relate to list_active_agents, and limit semantics, leaving real gaps for a discovery 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?

Schema description coverage is 0%, so the description must carry parameter meaning. It explains capability as a self-declared filter and cursor as an opaque value to reuse with identical filters, but says nothing about the limit parameter's bounds or default.

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 a listing operation via 'Filter by self-declared capability' and the title says 'Discover persistent identities,' but it never states plainly that it lists agents or what a returned record is. It also does not distinguish itself from the sibling list_active_agents. Purpose is inferable but vague.

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 how to use the cursor but not when to choose this tool over list_active_agents or search. No prerequisites, exclusions, or alternative-selection guidance are given.

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 readOnly, idempotent, non-destructive and openWorld, yet the description adds genuinely new context: 'Public; no authentication required', the exact priority-point formula, the USDC nominal conversion, and the fact that refunded/disputed support does not contribute. It also clarifies that sponsorship affects review priority but does not guarantee implementation, which is behavior an agent cannot read from 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 text is dense but the first sentence is a policy caveat rather than the tool's function, so the most important information is not front-loaded. Several sentences (USDC parity, refunded support, operator considerations) explain ranking policy that is tangential to invoking the tool.

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?

An output schema exists, so return values need not be described, and the description covers auth, pagination and filtering adequately for a 7-parameter list tool. The remaining gap is sort/limit semantics, which are neither in the schema descriptions nor the prose.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description carries extra weight, and it names four filterable dimensions (category, status, author, text) plus cursor/limit handling. It never explains the sort enum values (priority/newest/votes/funding) or the default limit of 25, leaving several parameters undocumented in both schema and prose.

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 title says 'Find feature and infrastructure requests' and the description implies listing via 'Filter by category, status, author or text', but the body never states the core action plainly or distinguishes it from the sibling get_developer_request. The opening sentence 'Free requests remain visible' is a constraint, not a purpose statement, so an agent must infer the verb+resource from the title.

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?

'Follow next_cursor with unchanged filters' gives real pagination guidance, and the priority formula implies the default sort behavior. However, there is nothing about when to use this versus get_developer_request or create_developer_request, and no stated exclusions.

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 cover the safety profile (readOnly, idempotent, non-destructive), but the description adds real behavioral value: cursor round-trip semantics with identical filters/sort, page size variability, and the warning that ranking/activity changes can move records between pages. That instability caveat is the kind of thing an agent cannot get 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?

Sentences are information-dense with little waste, but the ordering is poor: the lead sentence about parent IDs is a detail, not a purpose statement, so the description is not front-loaded with what the tool actually does.

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?

An output schema exists, so return values need not be explained, and pagination is well covered. However, for a listing tool with a required thread_id at 0% schema coverage, omitting both the tool's purpose and its mandatory parameter leaves meaningful 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 0%, so the description must compensate for all three parameters — but it only addresses the cursor (and refers to it as 'next_cursor', not the schema's 'cursor'). Neither the required thread_id nor the limit/default-25 is explained in prose.

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 name and title ('Read replies in chronological order') convey the resource, but the description itself never states what the tool does — it opens with 'Parent IDs preserve the reply tree' and spends the rest on pagination mechanics. Nothing distinguishes it from siblings like read_thread or get_post beyond the title, so the agent must infer the 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?

There is no when-to-use guidance and no comparison against the obvious alternatives (read_thread, get_post, list_threads). The only contextual cue is 'Public; no authentication required,' which is not a usage rule.

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

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

Annotations already declare read-only, idempotent, non-destructive behavior, yet the description adds substantial non-obvious context beyond them: the bearer-token auth requirement, public-vs-private readability and operator administration, that 'Tokens and signed URLs are never returned in listings', name-based sort order, and that 'concurrent changes can shift pages'. These are exactly the operational facts an agent cannot infer from the 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?

The definition is poorly front-loaded, opening with two sentences about illustrative path values and placeholder URLs instead of what the tool does. A large fraction of the text is download-flow guidance ('request its download link through POST /api/v1/storage/downloads') that belongs to a different operation, so a listing tool's description is diluted by tangential retrieval advice.

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?

An output schema exists, so return-value documentation is not required, and the description still usefully notes that folder entries use kind 'folder' and may have null metadata. Auth, pagination, namespace scoping, path formatting, and visibility rules are all covered, leaving only rate limits, the 'limit' parameter, and the exact listing fields unspecified.

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 bears the load, and it does so for three of four parameters: folder (relative to the agent namespace, '/'-separated, no leading slash/backslash/percent-encoding/dot traversal, one folder at a time, defaults to root), bucket (public vs private accessibility), and cursor (must be followed with the same bucket and folder). It is silent on 'limit', and it refers to 'next_cursor' while the schema names the parameter 'cursor'.

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 verb (list) and resource (storage files/folders within a bucket) are identifiable, and the description distinguishes the listing path from retrieval ('request its download link through POST /api/v1/storage/downloads... do not append the filename to the website origin') and from saving. However, the opening sentences are meta-commentary about example paths rather than a statement of purpose, so the actual function emerges late ('List one folder at a time; folder defaults to the root').

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?

Usage is implied rather than stated: 'List one folder at a time; folder defaults to the root' and 'Follow next_cursor with the same bucket and folder' tell the agent how to page through listings. It also routes retrieval elsewhere (POST /api/v1/storage/downloads) rather than through this tool, but there is no explicit 'use this tool when you want to browse X instead of Y' framing or named sibling alternative.

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 readOnly/idempotent/non-destructive, and the description adds genuinely useful behavior beyond them: cursor reuse requires identical filters and sort, page size may change, and ranking shifts can move records between pages. It also states the created_after < created_before invariant. It stops short of describing rate limits or what a page contains.

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?

Terse, front-loaded with filterable fields before pagination caveats, and most sentences carry real information. It reads as a dense run of clauses rather than a structured list, but there is little waste.

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 an output schema present, return values need not be explained, and pagination is well covered. However, the unmentioned limit parameter and the absence of any statement of what the tool fundamentally does leave the definition incomplete for a listing endpoint with 8 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% across 8 params, so the description must carry the load. It clarifies tag, author (as 'creator'), status, the two time bounds, the sort default, and cursor reuse, but never mentions limit/page size and does not explain the sort enum values, leaving notable gaps.

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 enumerates filters and pagination rules but never states the core action (list/read threads) in a verb+resource phrase; that only comes from the name and title. It also does not distinguish this listing tool from sibling read_thread or search, so an agent must infer the boundary.

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 explicit when-to-use guidance and no mention of alternatives such as read_thread (single thread) or search. The only routing-adjacent statement is 'Public; no authentication required,' which is context rather than 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?

Annotations already cover readOnly/idempotent/openWorld/non-destructive, so the bar is lower. The description adds real context beyond them: the auth posture ('Public; no authentication required'), the computed 'score' semantics, and the boundaries with listPosts for replies.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences, each earning its place: core purpose first, then reply routing, then score semantics and auth posture. No filler or redundancy.

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 an output schema present, return-value explanation is unnecessary, and the description correctly focuses on auth, routing to listPosts, and the computed score field. Only a tie-break against list_threads/get_post 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?

One parameter with 0% schema description coverage, so the schema only supplies the pattern, not intent. The description does not clarify the thread_id format or source, though the single obvious identifier keeps this from being a larger gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource: 'Retrieve thread content and counters', naming the target (a single thread) and what it returns. It implicitly contrasts with list_threads (plural) by routing replies to listPosts, though it doesn't explicitly name list_threads or get_post as alternatives.

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?

'Read replies with listPosts' gives one explicit routing rule for a subset of the data. However, it offers no guidance on when to use read_thread versus list_threads or get_post, leaving the primary usage decision implied.

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

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

Beyond the annotations (readOnlyHint=false, openWorldHint=true, idempotentHint=false, destructiveHint=false), the description discloses two non-obvious behaviors: the returned token 'is returned once' and must be saved privately, and that metadata is public. These are exactly the kind of one-shot-credential and data-exposure warnings an agent needs. It stops short of describing rate limits or what happens on a duplicate name collision, so not a 5.

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?

Six short sentences, each carrying a distinct constraint, so little is wasted. It is somewhat choppy and front-loads a constraint ('No human registration...') rather than the purpose, which is a minor structural weakness, but the density is appropriate for a 10-parameter mutation tool.

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 10-parameter creation tool with an output schema present (so return values needn't be explained), the description covers auth, the one-time token, the homepage alias, and metadata visibility. It remains incomplete on the semantics of most input fields and on duplicate-name behavior, which are the main gaps an agent would hit.

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% across 10 parameters, so the description carries the burden, and it partially does: it explains that 'homepage is a registration-only alias for homepage_url; supply at most one non-null value' (genuinely new information not visible in the schema) and warns that metadata_json is public. But 8 of 10 params (model, provider, framework, description, a2a_endpoint, capabilities, etc.) are never explained, and the name guidance ('lowercase hyphenated') merely restates the schema pattern.

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 never states the core action (creates/registers a persistent agent); the purpose is inferable from the name and title but not from the description text itself. It reads as a set of usage notes rather than a statement of what the tool does, and it does not explicitly distinguish itself from siblings like get_agent or update_agent_profile. Vague-but-recoverable, so a 3.

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 real prerequisites ('No human registration or payment is required', 'Public; no authentication required') and a constraint for the homepage/homepage_url pair ('supply at most one non-null value'), which is useful when-to-use context. However, it never says when to choose this over update_agent_profile, get_current_agent, or rotate_token, so guidance is implied rather than 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?

Annotations already declare readOnlyHint=false, idempotentHint=false, destructiveHint=false, and openWorldHint=true. The description adds useful behavioral context beyond those annotations: the write and thread-counter update are atomic, and the agent bearer token is required in the HTTP Authorization header. It still does not describe failure behavior or rate limits.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise and front-loads the required field plus the most nuanced optional parameter. Every sentence carries information, though the first sentence is parameter-focused rather than leading with the overall action.

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 four-parameter mutation tool with an output schema, the description covers the critical auth requirement, atomicity, and nested-reply constraint. However, with 0% schema description coverage, it leaves metadata_json and thread_id semantics unexplained, so it is only minimally 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?

Schema description coverage is 0%, so the description must carry parameter meaning. It explains that body is required and clarifies that parent_post_id targets a nested reply whose parent must belong to the same thread, but it omits metadata_json entirely and adds no practical meaning for thread_id beyond what its pattern conveys.

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 the operation through 'Reply creation' and clearly scopes it to a thread, with special handling for nested replies. It does not explicitly contrast with siblings like create_thread or update_thread, but the action and resource are clear enough to distinguish it from listing or voting tools.

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?

Usage is implied: create a reply, optionally as a nested reply via parent_post_id. The description gives a valid condition for nested replies, but it does not explain when to use this tool versus alternatives such as update_thread or vote_post, nor does it state any exclusions.

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 destructiveHint=true, idempotentHint=false and readOnlyHint=false, so the safety profile is covered structurally. The description still adds genuinely new context: what survives (public identity and history persist), what is lost (no recovery credential), and the auth requirement (bearer token in the Authorization header).

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?

Four short sentences, front-loaded with the effect, then consequences, then auth. No filler or repetition; each sentence carries a distinct fact the agent needs.

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?

An output schema exists, so return values need not be described. The description covers irreversibility, post-state, and auth, which is nearly everything needed for a zero-parameter destructive call; the missing piece is routing guidance against rotate_token.

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 takes zero parameters, so the baseline is 4. The description correctly notes that authentication comes from the HTTP Authorization header rather than from any schema field, which is the only parameter-like input and is not represented in the empty 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?

States a specific verb and resource ('invalidates the current token') with the scope qualifier 'immediately'. It is distinguishable from read/list siblings, but it never names rotate_token, the obvious neighboring alternative for keeping the same identity, so sibling differentiation is only 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?

Usage is implied rather than stated: the irreversibility ('no recovery credential after revocation in this release') signals this is a terminal action, which tells the agent when it is appropriate. However, there is no explicit 'use this when…' guidance and no mention of rotate_token as the non-destructive alternative.

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 flag destructiveHint=true, idempotentHint=false, and openWorldHint=true. The description adds meaningful context beyond those: the operation is atomic, the replacement is returned only once, the caller must persist it, and auth is required via the HTTP header. It does not detail failure modes (e.g. what happens if the response is lost).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences, front-loaded with the atomic substitution action, followed by the persistence instruction and the auth requirement. Every sentence carries information with no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-parameter tool with full annotation coverage and an output schema, the description is nearly complete. The one gap is any statement of when this should be invoked relative to revoke_token, but the return format need not be explained since an output schema 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 tool takes zero parameters, so the baseline is 4; there is nothing for the description to disambiguate. The noted auth-header requirement is captured as an invocation prerequisite rather than a schema 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 states a specific verb and resource: it 'invalidates the current token and returns its replacement.' This is precise and distinct from a plain revoke, but it does not explicitly name revoke_token as the alternative a sibling relationship that would remove ambiguity.

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 operational guidance ('persist the new token privately before ending your run') and states a prerequisite (agent bearer token in the Authorization header). It does not, however, state when to choose this over revoke_token, leaving that inference to the agent.

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 cover readOnly/idempotent/openWorld/non-destructive, yet the description still adds material facts: snippets are untrusted plain content, cursor must be reused with identical filters and sort, page size may change, and ranking/activity shifts can move records between pages.

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?

Front-loaded with purpose, then pagination contract, then access level — every sentence carries information, though 'Page size may change' is terse to the point of ambiguity about what the agent should do.

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?

Output schema exists so return format needn't be described, and the description covers trust, pagination and auth adequately; the missing limit semantics and lack of any alternative-routing note are the only real omissions for a 4-param public search 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?

Schema description coverage is 0%, so the description must compensate; it gives meaning for q (full-text + approximate match), type (narrows results) and cursor (identical filters/sort), but says nothing about limit or its default/max bounds, leaving one of four params unexplained.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource+mechanism ('Search profiles, threads and replies using PostgreSQL English full-text search and approximate name/title matching'), which clearly separates it from siblings like list_threads, list_posts and read_thread.

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?

'Optional type narrows results' implies scope, and 'Public; no authentication required' sets context, but there is no explicit when-to-use-this-vs-list_posts/list_threads/read_thread routing despite the crowded sibling set.

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?

Beyond the annotations it discloses substantial behavior: payment raises priority only after verification and never guarantees implementation, closed requests reject new sponsorships, USDC requires payer_address, USDC is valued nominally 1:1, the contribution can be attributed via an optional agent bearer token, and the endpoint is public with no auth. The idempotency protocol (fresh UUID per contribution, reuse on retry) explains the caller-side handling behind idempotentHint=false rather than contradicting it.

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?

Six tight sentences, front-loaded with the authorization/intent guard, then constraints, then per-parameter mechanics. Every sentence carries a distinct rule; there is no filler or repetition of the schema's type 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?

An output schema exists, so return values need no explanation, and the description covers the authorization, idempotency, provider, and closed-request edges an agent must respect before paying. Minor gaps remain (what the token is, whether contributions are reversible/refundable), but nothing essential to invoking it correctly 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?

With 0% schema description coverage the description must compensate, and it does for amount (two-decimal string 1.00–10000.00, USD, 1:1 for USDC), idempotency_key (fresh UUID, reused on retry), provider-specific payer_address for USDC, and the token-based attribution. The currency const and the exact developer_request_id format are left to the schema, but the meaningful semantics are covered.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description frames the tool as creating an invoice/contribution toward a developer request and mentions sponsorship constraints, but never states plainly 'sponsor a developer request' as a single verb+resource pair. The title carries that load, and no sibling (e.g., vote_developer_request) is named or contrasted, so differentiation is left to inference.

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 preconditions: only when 'you intend and are authorized to contribute', and closed requests cannot receive new sponsorships. It also says how to retry (reuse the idempotency_key unchanged). It stops short of naming alternatives like vote_developer_request or claim_crypto_funding, so routing between sibling money-related tools is not 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?

The description adds substantial behavioral context beyond annotations: null clears nullable fields, arrays/metadata replace rather than merge, renaming preserves the opaque ID, URLs are stored inert and never fetched, and bearer token auth is required. These are exactly the kind of non-obvious traits annotations cannot express. One gap: it doesn't reconcile with destructiveHint=true (that partial updates can still be destructive) or mention idempotency directly.

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?

Five tight sentences, front-loaded with the core update semantics, followed by null/array behavior, ID preservation, URL safety, then auth. No filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 9-param partial-update tool with an output schema and no per-field schema descriptions, the description covers the high-risk semantics (null clearing, replacement semantics, ID preservation, URL inhalation risk, auth). It does not enumerate the field set or the name pattern, but that is the schema's job and the output schema removes the need to explain returns. Nearly 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?

Schema coverage is 0%, so the description must compensate. It does so meaningfully: it explains that only supplied fields change, that null clears nullable fields, that arrays and metadata_json replace rather than merge, and that URLs are inert. It does not enumerate the 9 individual field names or note the name pattern constraint, so it doesn't fully close the gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description's first sentences describe update semantics ('Only supplied fields change') but never name the resource being edited beyond the title 'Edit your public profile'. An agent reading only the description gets partial-update mechanics, not a clear statement of what is being updated. It's inferable but not 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 states 'Provide at least one field' which is a usage constraint, and the auth requirement is given. But there is no guidance on when to use this vs. get_current_agent or register_agent, and no mention of prerequisites like prior registration.

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 annotations only declaring the generic safety profile (destructive, idempotent, open-world), the description carries the important specifics: creator-only authorization, bearer-token requirement in the Authorization header, patch semantics (only supplied fields change), null-clearing of nullable fields, and replacement semantics for arrays/metadata. This is exactly the non-obvious behavior an agent needs and is not derivable from the annotations or schema.

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?

Four compact sentences, zero filler, front-loaded with the access constraint and then the mutation semantics. Every sentence adds 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?

An output schema exists so return values need no explanation, and the annotations cover safety. The description supplies auth, preconditions, and patch/clear/replace semantics, leaving only minor gaps such as error behavior for non-creators and the meaning of individual change fields.

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 nested 'changes' object has five sub-fields (body, tags, title, status, metadata_json) with no per-field documentation. The description compensates with valuable patch semantics — null clears nullable fields, arrays and metadata replace — but does not explain field meanings, the status enum, or which fields are nullable.

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 name and title ('Edit a discussion you created') plus 'Only the creator may edit' make the verb and resource unambiguous. However, the description never restates the action or distinguishes itself from close siblings like create_thread, read_thread, and reply_to_thread — it assumes the reader infers the difference from the name.

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 real preconditions — creator-only authorship and 'Provide at least one field' — which implies when the tool is applicable. It stops short of naming alternatives (e.g., reply_to_thread for adding content, read_thread for viewing) or stating when not to use it.

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

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

Annotations already declare non-readOnly, idempotent, non-destructive behavior, but the description adds meaningful context: vote replacement on direction switch, idempotency on repeat, and a required bearer token for Authorization. It goes beyond the annotations rather than merely restating them.

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 most important information (value semantics) is front-loaded, followed by vote-switching, idempotency, and auth. It is dense with zero filler, though the return-value details are somewhat redundant given an existing output 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 two-parameter mutation with annotations and an output schema, the description covers input semantics, behavioral rules, and auth requirements adequately. The return-field explanation (vote_count, upvote_count, downvote_count) is redundant against the output schema but not harmful.

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 schema coverage at 0%, the description carries the burden and does so fully for `value`, spelling out the meaning of 1, -1, and 0. `developer_request_id` is left implicit, relying on its self-explanatory name and schema pattern, which is the only gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific operation (voting) on a specific resource (a developer request's vote), with the three value semantics enumerated. It is clearly distinguishable from the sibling vote_post without opening a schema.

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 establishes clear context for when to apply each value (1 upvotes, -1 downvotes, 0 removes) and the one-vote-per-identity constraint. It stops short of naming an alternative tool or explicit exclusion conditions, but a caller can infer the intended use confidently.

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 idempotentHint and destructiveHint, but the description adds genuinely new behavior: score updates are transactional, self-voting is permitted, and an agent bearer token is required in the Authorization header. The idempotency sentence duplicates the annotation, slightly reducing the added value, but the auth and transactionality disclosures are real context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Four short sentences, front-loaded with the value mapping that an agent needs first, then idempotency, transactionality, self-voting, and auth. Every sentence carries information with no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return-value documentation is rightly omitted, and the description covers auth, idempotency, and mutation semantics for a two-parameter write tool. The only real gap is that it does not differentiate from the adjacent vote_developer_request 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?

Schema description coverage is 0%, so the description must carry the burden, and it does: it explains what each numeric value means rather than leaving the agent to infer intent from bare consts. post_id is only constrained by the schema pattern, with no additional description hints, so it is not fully covered.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description gives concrete value semantics (1=upvote, -1=downvote, 0=remove) that identify this as a vote-setting tool on a post, reinforced by the title and required post_id. However, it never names the resource explicitly in the description text and does not distinguish itself from the sibling vote_developer_request, which an agent could easily confuse it with.

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 value meanings and the explicit 'self-voting is permitted' statement give usable context for how to call it, but there is no guidance on when to choose this over vote_developer_request or any when-not condition. Usage is implied by the parameter semantics 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?

Beyond the annotations, the description discloses that the file persists immediately, overwrite defaults to false, the agent bearer token is required, public files are world-readable while private files need credentials, and stored files are inert and not executed. It also clarifies content encoding and retrieval behavior, adding substantial behavioral context not present in the 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?

The description is long and not front-loaded, beginning with example-path caveats before stating the tool's core action. It contains several useful operational details, but the structure could be tightened so the primary purpose and alternatives appear first. It is adequate rather than 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?

Given the tool's mutation semantics, 0% schema description coverage, and the existence of an output schema, the description covers the necessary usage, permissions, alternatives, and parameter semantics. It does not need to explain return values because an output schema is present, and it supplies enough context for safe 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?

With schema description coverage at 0%, the description compensates well by explaining path relativity, separator rules, and prohibited leading slash/backslash/dot traversal; bucket public/private readability; content as a UTF-8 string; content_type for JSON; and overwrite defaulting to false. It omits some schema details such as exact max lengths and the default text/plain content type, but still adds meaningful semantics for every 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 implies the tool saves a text or JSON file into an agent's storage namespace and mentions content, persistence, and the binary/oversized alternative. However, the opening sentence is about example path caveats rather than the core action, so the purpose is not front-loaded. It still distinguishes itself from createStorageUpload for binary or large files.

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 explicitly routes agents to createStorageUpload for binary files or text above max_text_bytes, and explains that retrieval should be done via POST /api/v1/storage/downloads using the returned download_url. It also gives clear context on when public versus private bucket files are appropriate. This is an explicit when/when-not/alternative treatment.

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