Get Symbol Members

get-symbol-members
Read-onlyIdempotent

Lists members of a resolved C# type to inspect its declaration surface, optionally including inherited or interface members, without modifying source.

Instructions

Lists members of a resolved named type to inspect its declaration surface. Use get-api-surface for an accessibility-filtered API inventory or get-symbol-info for details about one member. Defaults to explicitly declared members of the selected type, including non-public members. includeInherited adds base-type members except private, implicit and constructor/destructor members. includeExplicitInterface adds declarations from all implemented or inherited interfaces, not just explicit implementations on the selected type. Both options default to false. Returns symbol and a distinct, bounded members collection; membersLimit defaults to 100. Check members.hasMore for truncation. Reads the loaded workspace without modifying source.

TDQS

A5/5.0
Behavior5/5

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

Goes well beyond the annotations by specifying exactly what includeInherited pulls in and what it excludes (private, implicit, constructor/destructor members), what includeExplicitInterface widens to, that both default to false, and that the members collection is bounded with a hasMore truncation signal. The closing "reads the loaded workspace without modifying source" is mildly redundant with readOnlyHint, but the rest is substantive non-obvious behavior.

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

Conciseness5/5

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

Front-loaded with purpose, then alternatives, then per-option semantics, then return/truncation behavior. Every sentence carries information an agent needs; there is no filler and no restatement of the tool name.

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?

For a 6-parameter tool with nested selector objects and an output schema, the description covers the decision-relevant surface: scope defaults, flag semantics, bounded results and truncation handling. Return-shape detail is correctly deferred to the output schema.

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

Parameters5/5

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

Schema coverage is 100%, so the baseline would be 3, but the description supplies semantics the schema flags lack: the schema only says "Whether inherited members should be included," while the description spells out the inherited-member exclusions and the all-interfaces-vs-explicit-implementations distinction. It also states membersLimit defaults to 100 and points at members.hasMore for truncation.

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+resource pair ("Lists members of a resolved named type") and states the intent ("to inspect its declaration surface"), which is a distinct purpose from any sibling. An agent can differentiate it from get-api-surface, get-symbol-info, and find-implementations 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 Guidelines5/5

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

Explicitly names two alternatives and the condition that selects each: get-api-surface for an accessibility-filtered API inventory, get-symbol-info for details about one member. It also establishes the default scope (explicitly declared members, including non-public), so the agent knows what it gets if it passes no flags.

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