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

With no annotations, the description carries the full behavioral burden. 'Reads' correctly signals a non-mutating inspection of local manifest files, and the enumerated outputs tell the agent what it gets back, but there is no disclosure of failure modes (missing/invalid composer.json, unreadable lock file) or environment requirements.

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?

One tightly constructed sentence, front-loaded with the action and inputs, then the outputs as a list. No filler or redundancy.

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 read-only tool with an output schema, the definition is sufficient: the inputs and result shape are stated. The remaining gap is edge-case behavior on unreadable or missing files, which the output schema does not cover.

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 single 'path' parameter has 0% schema description coverage, so the description must compensate. It adds meaningful context by saying the path refers to 'the given Magento project', implying a project root directory rather than an arbitrary file, but it stops short of clarifying whether it is a directory, a composer.json path, or absolute vs relative.

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 gives a specific verb ('Reads') and names both the resources (composer.json, composer.lock) and the exact outputs (Magento version, PHP requirement, package count, abandoned packages). An agent immediately knows this is a project-state inspection tool, which implicitly separates it from fetch_release_notes or upgrade_plan, but it never names a sibling 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?

There is no when-to-use guidance, no prerequisites, and no mention of the alternatives (check_updates, module_risk, upgrade_plan) or when one should be preferred over this one. The only hint is the implied use of reading project state, which the agent must infer from the name.

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