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

With no annotations, the description carries the burden of behavioral detail. It does disclose 'incrementally ingest' and 'atomically update affected indexes', which is useful, but it doesn't explain side effects, failure behavior, permissions, idempotency, or what 'allowed' means in practice.

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

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

One sentence with no fluff. The core action 'incrementally ingest and atomically update' is clear and front-loaded, and every word earns its place.

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

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

For a tool with no annotations, undocumented parameters, and multiple siblings, it is under-specified. It omits usage direction, parameter semantics, and behavior side effects; the output schema helps but doesn't make up for those gaps.

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

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

Schema description coverage is 0%, so the description must compensate for the paths and adapter parameters. It doesn't name either parameter or explain what paths and adapter expect, nor how they affect synchronization.

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

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

Clearly specifies a distinct operation: incrementally ingest allowed agent-session roots and atomically update indexes. This distinguishes it from the read-oriented sibling tools memory_search, memory_get, memory_explain, and memory_status.

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

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

No guidance is given about when to call this tool, when not to call it, or how it relates to memory_search and memory_get. The only contexts is inferred from the phrase 'sync', but the description never says when synchronization should be triggered.

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