Create Entry (Pin Image)

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

Annotations only state readOnly=false and destructive=false. The description adds genuinely useful behavior beyond that: the image is fetched and copied into Bowrd storage rather than merely linked. It still omits error cases (invalid or unreachable URL, duplicate entries) and the public-visibility default, but the main side effect is disclosed.

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

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

Two short sentences, front-loaded with the action and followed by the key side effect. Nothing is repeated and 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?

For a create tool with seven parameters, the description covers the core action and the storage side effect but says nothing about the result (e.g., whether an entry ID is returned) or failure modes. With no output schema, some note on the return value would help.

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

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

Schema description coverage is 100%, so all seven parameters are documented in the schema, including defaults like is_public=true. The description adds little parameter-level meaning beyond 'the specified board', so the baseline of 3 applies.

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

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

The description states a specific verb and resource ('Create a new pin/entry in Bowrd') and adds the non-obvious effect that the image is downloaded and attached to a board. It does not distinguish itself from siblings such as bowrd_scrape_images_from_url or bowrd_create_board, so an agent still has to 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?

Usage is implied: create a pin on an existing board with an image URL. There is no explicit guidance on when to use this versus bowrd_scrape_images_from_url (which presumably yields image URLs to feed here) or what prerequisites exist, such as the board already existing.

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