gograph_embeds

Read-onlyIdempotent

Find all Go structs that embed a specified struct via anonymous field composition, revealing how a base type is extended throughout the codebase. Useful for estimating blast radius before modifying shared embedded structs.

Instructions

Find all Go structs that embed the named struct via anonymous field composition. Requires .gograph/graph.json — run gograph build . first. Read-only; no side effects. WHEN TO USE: When understanding how a base type is extended throughout the codebase, or before modifying a shared embedded struct to estimate blast radius. NOT TO USE: For interface implementations (use gograph_implementers); for named field type references in other structs (use gograph_usages). RETURNS: List of embedding parent struct names with package paths and file locations; empty when the struct is embedded nowhere.

Behavior4/5

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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, openWorldHint=false. The description adds the prerequisite (requires .gograph/graph.json) and confirms no side effects. It also describes the return format, which is not covered by annotations.

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?

The description is concise, front-loaded with purpose, and every sentence adds value. No wasted words.

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?

Despite the absence of an output schema, the description explains the return type (list of parent struct names with package paths and file locations). It also covers prerequisites and usage guidance, making it complete for a single-parameter tool with rich annotations.

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% with a clear description of the 'struct' parameter including examples. The description does not add additional meaning beyond the schema, so baseline 3 is appropriate.

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?

The description clearly states the verb 'Find', the resource 'Go structs that embed the named struct', and the mechanism 'via anonymous field composition'. It distinguishes from siblings by mentioning alternatives for interface implementations and named field 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?

The description explicitly provides WHEN TO USE (understanding base type extension, estimating blast radius) and NOT TO USE (for interface implementations use gograph_implementers; for named field type references use gograph_usages). This offers excellent guidance.

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