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

Annotations already declare readOnly, idempotent, non-destructive and open-world behavior, so the safety profile is covered. The description adds real context beyond them: the 12-month window for the fixes-per-feature metric and the fact that the target must already be an imported repository. It says nothing about cost, latency, or what happens if the repository has not been imported.

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 with the resource first and the returned categories after; no filler or marketing language. The long comma-separated enumeration is dense but each clause carries a distinct metric, so nothing is wasteful.

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?

An output schema exists, so the description is not obliged to explain return values, and the prerequisite of an already-imported repository is surfaced. The remaining gap is the missing pointer to how a repository becomes 'imported' (presumably hokmah_connect_project) and no differentiation from the analysis siblings.

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 0% and there is one required parameter, but the description never names or explains repo_url. The phrase 'an imported repository' hints that the argument refers to a previously imported repo rather than an arbitrary URL, which is useful, but no format, example, or behavior for an unknown/unimported URL is given.

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 the resource (an imported repository) and enumerates the specific signals returned: fragility via fixes-per-feature over 12 months, growth, churn, largest files, co-change, and unresolved internal imports. That is far more specific than the bare name. It does not, however, explicitly contrast itself with hokmah_analyze or hokmah_zone_health, so the sibling boundary is left to 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?

There is no when-to-use or when-not-to-use guidance and no named alternative among the five siblings. An agent must guess whether this is the entry point before hokmah_analyze or a complement to hokmah_zone_health. The word 'Overview' faintly implies 'start here', but that is inference rather than guidance.

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