get_project_overview

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

Discloses that it reads specific files (composer.json, symfony.lock, .env) and reports certain information. As a read-only operation with no side effects, this is adequate, though it doesn't explicitly state it is read-only or mention failure scenarios.

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?

Description is structured with bullet points and front-loaded with purpose. Every sentence adds value, though the bullet list could be slightly more concise without losing clarity.

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 no parameters and an output schema exists, the description fully explains the output content and provides usage context (call first). It is complete for a tool meant for initial project overview.

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?

No parameters exist, so schema coverage is 100%. The description correctly omits parameter details as none are needed, meeting the baseline for zero-parameter tools.

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?

Clearly states the output is a Markdown overview of the Symfony project, listing specific data points (PHP version, Symfony version, packages, etc.). It distinguishes itself by instructing to call this tool first, differentiating it from sibling tools.

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?

Explicitly says 'Call this tool first before using other tools to understand the project,' providing clear context. It doesn't mention when not to use it, but this is acceptable given its role as an initial discovery tool.

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