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

No annotations are provided, so the description carries the full behavioral burden. It does disclose a meaningful trait beyond the schema: the implicit default target of wiki/logs/YYYY-MM-DD.md. But it does not say whether the file is created if absent, whether the operation is idempotent, what permissions are needed, or what is returned.

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

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

Two short sentences, zero waste, with the core action front-loaded and the default-destination rule immediately after. Nothing is padded or redundant.

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?

Adequate minimum for a 3-parameter mutation tool with no annotations and no output schema: the action and default target are clear. It stops short of covering creation-on-missing-file, failure modes, or return behavior, which an agent would benefit from knowing before calling.

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 100%, so the baseline is 3, and the description earns an extra point by adding real semantics beyond the schema: 'path' omitted means the note goes to the current day's log file. The default-path behavior is not derivable from the schema's 'Optional target page.'

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 ('appends') and resource ('note or log entry'), which is distinguishable from write_page's full-page write by the append semantics. It never names a sibling or explicitly contrasts with write_page, which is the only thing keeping this from 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?

Implies usage for quick notes and specifies the default destination when 'path' is omitted, which is genuinely useful routing information. However, it gives no explicit when-to-use guidance versus write_page, nor any exclusions or prerequisites.

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

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

With no annotations, the description carries the full behavioral burden. 'Lists' implies a read, but it does not disclose whether the listing is recursive, whether it includes subfolder contents, output format/ordering, or pagination for large wikis — meaningful gaps for a tool with zero annotation coverage.

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

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

Two short sentences, front-loaded with the core action and followed by the optional scope modifier. Slightly redundant with the schema's subdir description, but nothing extraneous.

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?

A simple one-param read tool needs little, but with no annotations and no output schema the description should clarify the return shape (paths, relative vs absolute) and listing depth. It adequately identifies what is listed but leaves the result contract implicit.

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 100% and the single param is fully documented in the schema, so baseline 3 applies. The description merely restates the optional subfolder without adding syntax, path-format, or behavior details beyond the schema.

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

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

States a specific verb and resource (lists pages in the wiki) plus the file types involved (.md/.html). It does not explicitly contrast itself with siblings like search or read_page, but the enumeration intent is unambiguous.

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

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

Usage is only implied: an agent can infer this is for enumerating pages, but there is no guidance on when to prefer it over search, nor any note on prerequisites or scope limits.

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?

No annotations are provided, so the description carries the full behavioral burden. It conveys that this is a read of existing content and gives the path format via example, but says nothing about failure modes (missing page), permissions, or what the returned content looks like. For a low-risk read tool this is acceptable but thin.

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

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

A single front-loaded sentence naming the verb, resource, and required argument, with an example parenthetical that earns its place. Nothing extraneous, though it is minimal rather than exemplary.

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

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

For a one-parameter read tool with no output schema and 100% schema coverage, the description covers the essentials needed to invoke it. The only mild gap is undisclosed behavior when the path does not exist.

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 100%, so the baseline is 3. The description adds a concrete example ('notes/example-note.md') that clarifies the relative-path format and extension convention beyond the schema wording, providing marginal added meaning.

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 ('Reads'), a clear resource ('the content of a wiki page'), and the required input ('given the relative path'), including a concrete example. It implicitly contrasts with write-oriented siblings (write_page, append_note) but 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?

There is no guidance on when to choose this tool over siblings like list_pages or search, nor any prerequisites. An agent must infer that read_page fetches one known page while search finds pages. No when-not or alternative routing 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?

With no annotations, the description carries the full behavioral burden. It usefully discloses the case-insensitive default and that the scope is all wiki pages, but omits the return format (page names vs. snippets) and any pagination/limit behavior, leaving key traits unstated.

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

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

A single front-loaded sentence with no filler or redundancy. The core purpose and behavior are conveyed immediately.

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 search tool with no output schema, the description should indicate what matches look like or how results are returned; it does not. It is adequate to invoke but leaves the agent guessing about return shape and result ranking.

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 100%, so the schema already documents query, subdir, max_results, and case_sensitive. The description adds only the case-insensitivity default, which duplicates the schema's default value, so baseline 3 is appropriate.

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

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

States a specific verb+resource (full-text search across wiki pages) and the default matching behavior. It distinguishes itself from list_pages/read_page by scope (searches all pages) but never explicitly names a sibling or when to prefer each.

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 or when-not-to-use guidance. It never tells the agent to use search when hunting for unknown content versus read_page for a known page, nor does it mention any alternatives. Only implicit usage is conveyed.

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

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

With no annotations, the description carries the full behavioral burden. It usefully discloses the non-obvious extension normalization ('If the extension is missing .md is added'), but says nothing about permissions, whether parent directories are created, or that the default overwrite=true silently replaces existing content.

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

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

Two short sentences, zero filler, with the core action stated first and the normalization caveat second. Nothing could be trimmed without losing information.

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

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

For a simple 3-parameter write tool with no output schema, the description covers the essential action and one surprising side effect. It is nearly complete, with only minor gaps around error/failure behavior and directory handling.

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

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

Schema description coverage is 100%, so the schema already documents path, content, and the overwrite=false refusal behavior; this sets the baseline at 3. The description adds one genuinely extra rule (automatic .md extension appending) beyond the schema, but nothing further about the parameters.

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

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

The description names a specific verb pair and resource ('Creates or overwrites a wiki page'), which is clearly distinguishable from read_page and list_pages. It does not differentiate from append_note, the other write-capable sibling, so it stops short of 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?

There is no explicit statement of when to use this tool versus append_note or the read-side siblings, and no prerequisites are mentioned. 'Creates or overwrites' only hints at the create-vs-update distinction that the overwrite parameter actually governs.

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