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

Annotations already declare readOnly, idempotent, openWorld, and non-destructive behavior, so the description's main added value is the shape of the output artifact. It does not disclose the openWorld variability (results depend on external labor-market/LMS knowledge) or how exhaustive paths are, which is exactly the context the lower annotation bar would reward.

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 dense sentence with the action and output structure front-loaded; every clause contributes. It is compact, though the long list of path components makes it slightly list-like rather than fully structured.

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?

With an output schema present and full parameter descriptions, the description's job is to convey purpose and artifact content, which it does. The remaining gap is usage routing (when to choose this over skill-gap analysis), which is not fully covered.

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 description coverage is 100%, so the schema already explains resume_data and job_description_data fully. The description only echoes them at a high level ('person's profile and target role') and adds no format or edge-case guidance, so baseline 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 and artifact ('Builds structured learning paths') and enumerates the path's contents (prerequisites, skill sequence, certifications, proficiency targets, LMS alignment), which distinguishes it from neighbors like analyze_skill_gap or map_job_to_skills. It does not explicitly contrast with any sibling, so it stops short of 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?

The phrase 'based on a person's profile and target role' implies the usage context (a resume plus a target job), but there is no explicit when-to-use, when-not-to-use, or pointer to complementary tools such as analyze_skill_gap. Usage is inferable rather than stated.

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