memory_init

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

With no annotations, the description carries the full burden of behavioral disclosure. It mentions that the tool returns a briefing, but it does not state whether 'init' creates or overwrites project memory, whether the operation is read-only, or what side effects it may have. For a tool that could mutate project memory, this is a significant gap.

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?

Three short sentences each convey distinct, relevant information: the action, the timing, and the return value. There is no filler or redundancy, and the most important instruction is front-loaded.

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?

There is no output schema and no annotations, so the description should explain what the 'briefing' contains and any side effects, but it only says 'Returns briefing.' It also does not situate the tool among the many memory_* siblings, leaving an agent with insufficient information to fully anticipate behavior.

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 100%, so the schema already documents both parameters. The description adds no additional meaning about how project_id or project_name should be used, so the baseline score of 3 is appropriate.

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?

The description states a specific action ('Init or load project memory') and a defining instruction ('Call first in any session'), making the tool's role fairly clear. However, it does not name any sibling tool or explicitly differentiate itself from memory_read/memory_retrieve, which leaves some ambiguity about its exact scope.

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?

The description provides an explicit temporal guideline ('Call first in any session') that tells an agent when to invoke it. It does not describe when not to use it or name alternative memory tools, so it falls short of a full when/when-not comparison, but the context is clear.

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