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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds useful context about the actual content returned (the specific guidance topics), which goes beyond the annotations. It does not contradict any annotations and provides a reasonable sense of what the tool delivers.

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 two sentences, front-loading the core purpose in the first sentence and adding a relevant statistic in the second. There is no redundancy or fluff; every word adds value. It is appropriately concise for a tool with a single parameter.

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?

The tool is simple (one parameter, read-only, idempotent) and has an output schema that covers the return structure. The description explains the content scope and the target audience. Nothing an agent needs to decide whether to call this tool is missing. The mention of Marian's mentees provides additional context about the tool's provenance, though it is not essential.

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% for the single 'context' parameter, which is fully described in the schema. The description does not add any additional meaning about the parameter, as it focuses on the tool's output rather than its input. Baseline of 3 is appropriate since the schema already documents the parameter adequately.

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 clearly states the tool provides guidance for the IC→manager transition and enumerates the specific content it contains (responsibility triangle, failure modes, self-check questions, first months). This is a specific verb-resource pairing that distinguishes it from sibling tools like assess_team_lead_readiness, which presumably focus on assessment rather than guidance.

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 description implies when to use it (for first-time managers) but does not explicitly state alternatives or exclusion criteria. It mentions that 52% of mentees arrive at this transition, hinting at a common scenario, but gives no direct guidance on when to use this tool versus siblings like assess_team_lead_readiness or get_one_on_one_playbook. Usage is inferred rather than stated.

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