Get Symbol Attributes

get-symbol-attributes
Read-onlyIdempotent

Inspect attributes on a resolved C# symbol to retrieve types, inherited flags, and rendered constructor/named arguments; optionally include inherited attributes without executing constructors.

Instructions

Inspects attributes attached to a resolved symbol, returning their types, inherited flags and rendered constructor and named arguments. Use this for attribute metadata; use get-symbol-info for general symbol details. Defaults to directly declared attributes. includeInherited follows base types or overridden methods, properties and events, honours Inherited and AllowMultiple settings, and does not traverse interface declarations. Returns symbol and a bounded attributes collection; attributesLimit defaults to 50. Check attributes.hasMore for truncation. Reads Roslyn metadata without instantiating attributes or executing their constructors.

TDQS

A4.6/5.0
Behavior5/5

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

Annotations already declare readOnly/idempotent/non-destructive, but the description adds genuinely new behavioral facts: attributes are not instantiated and their constructors are not executed, results are bounded with attributes.hasMore signalling truncation, and interface declarations are never traversed. The Inherited/AllowMultiple handling is a subtle correctness detail an agent could not infer from the schema.

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?

Purpose and the sibling distinction are front-loaded, and the following sentences each carry distinct information (inheritance semantics, limit/truncation, no-instantiation guarantee). The result is dense but slightly overpacked, with several clauses chained into single sentences.

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

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return shape needs no prose, yet the description still covers truncation signalling via attributes.hasMore and the inheritance edge cases. For a read-only, five-parameter, nested-schema tool, nothing an agent needs to call it correctly is missing.

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

Parameters4/5

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

Schema coverage is 100%, so the baseline is 3, but the description goes beyond the schema's one-liner for includeInherited by defining its traversal rules (base types, overridden methods, properties and events; honours Inherited and AllowMultiple; excludes interfaces) and by restating the attributesLimit default of 50 with the hasMore truncation signal. The symbol selector, workspace and expectedSnapshot parameters get no added explanation, keeping this from a 5.

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

Purpose5/5

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

Opens with a specific verb and resource ('Inspects attributes attached to a resolved symbol') and enumerates what is returned (types, inherited flags, rendered constructor and named arguments). It explicitly separates itself from get-symbol-info, so an agent can distinguish the two without opening a schema.

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

Usage Guidelines4/5

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

Names the sibling alternative ('use get-symbol-info for general symbol details') and states the default scope ('Defaults to directly declared attributes'), which tells the agent what happens if it omits includeInherited. It stops short of stating prerequisites such as needing a resolved symbol from resolve-symbol first, which is implied but not spelled out.

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