Diff two memgraph snapshots

diffMemgraphs

Compare baseline and comparison .memgraph files to detect memory leak byte deltas and class count changes, identifying new, gone, or persisted root cycles for verifying fix effectiveness.

Instructions

[mg.memory] Compare a baseline .memgraph (before) against a comparison .memgraph (after). Returns total leak/byte deltas, classes whose counts increased or decreased, and ROOT CYCLE signatures bucketed into newInAfter / goneFromBefore / persisted. The killer feature for verifying that a fix actually worked.

Behavior3/5

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

Describes outputs but no annotations. Does not declare safety (read-only) or limitations. With no annotations, more detail on side effects or permissions would improve transparency.

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?

Two sentences, no filler. Front-loaded with purpose and outputs, ends with value statement. Every sentence earns its place.

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

Completeness4/5

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

Covers purpose and outputs well without output schema. Could mention file existence or format constraints, but schema already covers paths. Suitable for the tool's complexity.

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 covers 100% of parameters with descriptions. The description adds little beyond schema, baseline 3 applies.

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 tool compares two memgraph snapshots and returns specific deltas and cycle signatures. It distinguishes from siblings like analyzeMemgraph (single snapshot) and detectLeaksInXCUITest (XCUITest-specific).

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

Usage Guidelines3/5

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

Implied usage for verifying a fix worked, but no explicit when-not-to-use or comparisons to siblings. Lacks guidance on prerequisites or context.

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