get_card_project

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. With no output schema, the description's enumeration of returned content (customizations, paper/color options, per-customization pages) adds genuine value, but it says nothing about authorization requirements, missing-project behavior, or response size.

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 opens with the verb and resource and then spends its words on concrete return contents rather than filler. The parenthetical enumeration is dense but every item earns its place given there is no 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 simple single-parameter read with annotations covering safety and no output schema, this is close to complete: the agent knows the input source and roughly what comes back. A note on empty/missing projects or an explicit sibling reference would close the remaining gap.

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

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

Only one parameter and schema description coverage is 100%; the schema already documents project_uuid and even its source (list_card_projects). The description adds no format, casing, or example detail beyond that, so this is the baseline 3 for high-coverage schemas.

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 (get full details for one invitation project) and enumerates the sub-resources returned: invitation, envelope, RSVP card, details card, paper/color options, per-customization pages. This is clearly distinct from list_card_projects (collection) and get_card_suite, though it never names those siblings 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?

Usage is implied by the resource: fetch the single project you already have a UUID for. There is no explicit when-to-use statement or routing to alternatives like list_card_projects, get_card_project_guests, or get_card_suite; the schema's 'Project UUID from list_card_projects' carries the only real sequencing hint.

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