+}Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is fully covered structurally. The description's added value is the deprecation lifecycle note, which annotations cannot express, but it says nothing about legacy field normalization or validation behavior that the schema hints at.
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?
Two short sentences with no filler. The one structural weakness is that the deprecation warning — the most decision-relevant fact — sits in parentheses after the functional description rather than being front-loaded.
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?
An output schema exists, so return values need not be described, and the tool takes no required parameters beyond transport fields. The deprecation status and replacement are stated, which is the key context an agent needs; only the legacy-normalization behavior is left implicit.
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% and both parameters (locale, idempotencyKey) are documented as transport-level fields, not service inputs. The description adds no parameter meaning beyond the schema, so the baseline of 3 is appropriate.
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?
Specific verb ('Read') plus resources ('learning paths and public starting links'), and it explicitly identifies itself as a deprecated alias for academy_start, which disambiguates it from the many sibling academy_* tools. It stops short of 5 because 'public starting links' is vague phrasing that an agent must interpret.
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 names the preferred alternative (academy_start) and the condition under which this tool is superseded, plus the 'retained for one version' lifetime note. It does not say whether there is any remaining case where this tool is still correct to call, which keeps it out of 5 territory.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
