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

With no annotations, the description carries the full burden. For a zero-parameter information retrieval tool, it transparently indicates the returned data (profile details) and recommends call order. No side effects are implied or expected, and none are hidden, so it is adequately transparent.

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?

The description is a single, efficient sentence that front-loads the core purpose ('Who Djaouad Frih is') and then lists included details, with the usage hint 'Call this first' at the end. No wasted words.

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 the tool's simplicity (no params, no output schema), the description fully covers what the agent needs: what the tool returns, the recommended call order, and enough detail to decide whether to invoke it. Nothing essential is missing.

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 tool has zero parameters, so the schema (empty) covers 100% of the parameter surface. The description adds useful output context, which aligns with the baseline of 4 for no-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?

The description states a specific verb ('get') and resource ('profile'), and explicitly lists the content (stack, products, availability, contact). It clearly differentiates from siblings like get_pricing and search_projects by focusing on the person's identity and background.

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 imperative 'Call this first' provides explicit sequencing guidance, and the listed contents imply when it is appropriate (when needing background on Djaouad). However, it does not explicitly state when not to use it or mention alternative tools for other needs, so it stops short of full-exclusion guidance.

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