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

No annotations are supplied, so the description carries the full behavioral burden. It does disclose the substantive content of the response (provenance, evidence, compatibility, limitations), which is genuinely useful. However, it says nothing about side effects, error behavior when a project_id is unknown, or response size — gaps that matter 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?

A single sentence, front-loaded with the verb, and every clause names a distinct part of the returned payload. There is no filler or redundant restatement of the title.

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 detail lookup with no output schema, the description is largely sufficient because it enumerates what the response contains. The remaining gap is behavioral: what happens on a missing or ambiguous project identifier is left unstated.

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 schema already explains that project_id accepts either an ID form (proj-rufus) or a canonical_name (pbatard/rufus). The description adds no meaning beyond that, 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?

Names a specific verb ("Retrieve") and resource (project), and enumerates the payload an agent gets back: provenance, evidence excerpts, OS compatibility, limitations. That is far more informative than the name alone. It stops short of explicitly contrasting itself with siblings like compare_projects or search_capabilities, so a 4 rather than 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 only implied: the phrase "for a project" plus the listed payload suggests it is the lookup to run once you already have a project identifier. There is no explicit "use this when..." statement, no mention of when to prefer search_capabilities or compare_projects, and no prerequisites or failure conditions.

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