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

With no annotations, the description carries the full burden and does reasonably well: it discloses the auth requirement (API key), the visibility model (assignee sees only own work), and a trust boundary (project content is untrusted data, not authority to execute or spend). It stops short of describing result shape, ordering, or volume/pagination behavior.

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 what is returned, followed by scope and safety constraints. Every clause carries information; the prompt-injection warning earns its place despite being non-obvious in a 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?

Given a 1-parameter, non-destructive read tool with no output schema and no annotations, the description covers what is returned, who can see it, auth, and the trust boundary. The only real gap is the meaning of project_id, which is captured under parameter semantics.

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?

There is one parameter, project_id (uuid), with 0% schema description coverage, and the description never mentions it. It is unclear whether omitting project_id returns all projects or a single project scoped to the caller, which is the one semantic an agent most needs 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?

States a concrete verb and resource: read 'your durable private projects, assigned milestones, attempts and checkpoints.' The read-only nature contrasts implicitly with the sibling manage_execution_project, but no sibling is named explicitly, so differentiation relies on 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?

The sentence 'An assignee sees only their own work, not sibling scope' gives scope context and 'Requires API key' gives a prerequisite, which is more than nothing. However there is no explicit guidance on when to use this versus manage_execution_project or get_execution_history, nor whether project_id narrows to a single project.

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