Get Symbol Dependents

get-symbol-dependents
Read-onlyIdempotent

Find enclosing symbols that reference a resolved symbol to identify incoming dependencies; scope the search to selected documents, projects, or the loaded solution.

Instructions

Finds distinct enclosing symbols at source references to a resolved symbol. Use this to identify incoming dependencies; use get-symbol-dependencies for outgoing dependencies, find-references for individual source occurrences, or get-change-impact for relationship counts. Searches the selected documents or projects, or the loaded solution when scope is omitted. Returns up to 100 dependent symbol references by default; check dependents.hasMore before treating the results as complete.

Input Schema

NameRequiredDescriptionDefault
scopeNoLimits the source references used to discover dependents to the selected documents or projects; omitted searches the loaded solution.
symbolYesProvide exactly one of location or documentationCommentId.
workspaceNoProvide workspaceId, alias, path, or any combination.
dependentsLimitNoCaps returned distinct dependent symbols. Omitted or null uses 100; zero returns no dependents.
expectedSnapshotNoEcho the snapshot returned with the data or transaction state used to construct this request.

TDQS

A4.5/5.0
Behavior4/5

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

Annotations already establish read-only, idempotent, non-destructive, closed-world behavior, so the description need not restate safety. It adds real operational context beyond them: a default cap of 100 dependents and the instruction to check dependents.hasMore before treating results as complete — a truncation behavior an agent would otherwise miss. It stops short of explaining what 'distinct enclosing symbol' collapses (e.g., multiple references in one method) or how snapshot staleness is surfaced.

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?

Four sentences, each doing distinct work: definition, sibling routing, scope default, result-completeness warning. The most decision-relevant content (what it finds and which sibling to prefer) is front-loaded with zero filler.

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 need not be explained, and the description still flags the one output property that changes agent behavior (hasMore). For a read-only query with a nested but fully documented schema, nothing needed to invoke it correctly is missing.

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 scope, symbol, workspace, dependentsLimit and expectedSnapshot are already documented in structured fields — and the description's scope and limit sentences largely restate those. The one added nuance is framing the limit as a completeness hazard via hasMore, but no new meaning is given for the symbol selector or expectedSnapshot beyond the schema.

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?

States a specific verb and resource — 'Finds distinct enclosing symbols at source references to a resolved symbol' — which is precise enough to distinguish it from find-references (raw occurrences) and get-symbol-dependencies (outgoing edges). The name-plus-description pair leaves no ambiguity about what is returned: dependent symbols, not references.

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 routes the agent: 'use get-symbol-dependencies for outgoing dependencies, find-references for individual source occurrences, or get-change-impact for relationship counts.' That is a named alternative for each plausible confusion, plus a stated default-scope rule ('the loaded solution when scope is omitted').

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