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

Annotations already cover readOnly/destructive/openWorld, yet the description still adds substantial behavior: the required 'See your profile' (profile:read) permission, the interactive sign-in prompt when the member has not connected Automate America, the privacy rule that addresses are never served, and a prompt-injection warning about member-written content. These are exactly the operational facts an agent cannot infer 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?

Purpose is front-loaded, then return fields, then the permission/auth requirement, then the safety notice — a sensible ordering. A few phrases are awkward ('in their editor's order', 'With the id each change takes'), the latter being an out-of-place fragment that slightly blunts the otherwise tight structure.

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

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

With no input parameters and no output schema, the description carries the full burden of describing results, and it does so by enumerating every returned field and explicitly noting what is withheld. Permission scope, sign-in behavior, and content-safety posture are all covered, leaving nothing an agent needs to call 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?

The tool takes zero parameters, so the baseline is 4 and no parameter explanation is owed. The trailing sentence 'With the id each change takes' is a stray reference to mutation tools and adds no parameter meaning here.

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 and resource ('Read your member's Projects') and then enumerates the returned fields (title, type, date, About, client, hasImage, hasVideo), so an agent knows exactly what data this yields. It does not explicitly distinguish itself from overlapping siblings such as get_my_profile, which may also surface project data, so it falls 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?

Usage is implied by the name and the 'Every project on your member's profile' scope, which is adequate for a no-parameter list tool. However, there is no explicit statement of when to call this versus get_my_profile or list_my_posts, and no conditions or exclusions are given.

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