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

Annotations cover the safety profile (readOnlyHint=false, destructiveHint=false, idempotentHint=false, openWorldHint=false), so the description's job is to add state-change detail — and it does: the pipeline is usable at once and is seeded with the default pipeline's stages (New, Won, Lost). It does not mention permissions, return payload, or duplicate-name handling.

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?

A single sentence with the key behavioral fact (usable immediately, default stages) front-loaded and a routing pointer appended. No filler, no restatement of the title.

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 one-parameter create tool with no output schema, the essentials are present: what is created, that it is immediately usable, and its initial stages. The only real gap is the semantics of the 'name' parameter, which neither the schema nor the description documents.

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% for the single required 'name' parameter, and the description never mentions it at all — no naming rules, uniqueness constraints, or format. The description compensates with behavioral context (default stages) but adds nothing about the parameter it takes.

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?

States a specific verb and resource ('Make a pipeline') and immediately describes what the created object looks like. It also names the pipeline sibling it is not (save_a_pipeline) for stage edits, so an agent can distinguish create vs. modify without opening a schema.

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 implies when this is used (you need a new pipeline, usable immediately) and points to save_a_pipeline for changing stages. It does not state prerequisites, exclusivity, or when-not to use it versus other creation siblings, so guidance is implied rather than explicit.

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