velixar_session_save

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

With no annotations, the description carries full burden. It discloses auto-generation of session_id and return of session_id, but does not specify whether providing an existing session_id overwrites the record, or if there are any side effects (e.g., requires certain permissions, rate limits). The behavior is minimally transparent.

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?

The description is two sentences, both front-loaded with key information. No unnecessary words. Every sentence contributes: first states purpose, second explains auto-generation and return.

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 simple 3-parameter tool with no output schema, the description covers the core function and return value. It omits behavior when session_id is provided (overwrite vs. create new) and doesn't describe tags, but is otherwise sufficient for basic use.

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 coverage is 100% (all parameters described in schema). The description adds only one extra detail: 'Auto-generates session_id if not provided.' For tags, the schema says 'Additional tags' and description omits them entirely. The description adds marginal value beyond the schema.

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 clearly states the tool's action: 'Save a session summary for later recall.' It specifies the resource ('session summary') and distinguishes from sibling tools like 'velixar_session_recall' and 'velixar_session_resume' by being the save counterpart.

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 no guidance on when to use this tool versus alternatives such as 'velixar_store' (for arbitrary data) or 'velixar_update' (for updates). It does not clarify the context where saving a session summary is preferred.

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