TDQS

C2.6/5.0
Behavior2/5

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and a closed world, so the safety profile is fully covered. The description adds nothing beyond that: no mention of the snapshot/consistency contract implied by expectedSnapshot, no truncation behavior for parametersLimit/declarationsLimit, and no note that the symbol must be pre-resolved.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence with zero padding or repetition. It is efficient, though arguably so terse that it leaves no room for the routing and snapshot context this tool needs.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

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, but this is a six-parameter tool with deep nested objects and a disambiguation workflow (span vs selection, project/document disambiguators, expectedSnapshot). A single generic sentence leaves the agent without the prerequisite (a resolved symbol) or the consistency expectation that the schema hints at.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the nested selector, workspace, limits, and snapshot fields are already documented in the schema; baseline 3 applies. The description contributes no additional meaning, such as the significance of echoing expectedSnapshot or how the two limits interact.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

It names a concrete verb and resource ('Returns detailed metadata for a resolved symbol'), which is better than a tautology, but 'metadata' is vague about what is actually returned. It does not differentiate from siblings such as get-symbol-members, get-symbol-attributes, or get-code-context, all of which also operate on a resolved symbol.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no explicit when-to-use guidance, no exclusions, and no named alternatives. The phrase 'resolved symbol' faintly implies a prior resolve-symbol step, but the agent must infer that; nothing states when this tool should be preferred over the other symbol-info siblings.

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