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

With no annotations, the description carries the full burden and does well on the core trait: it discloses that the operation mutates the watch list, enumerates the seeded data, and states idempotency ('skips addresses already watched'). It omits permission/auth requirements and whether the seeded entries can be undone, which leaves a real gap for a write tool.

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?

Front-loaded with the primary routing cue (one-shot cold-start) and three tight sentences that cover trigger, payload, and follow-up with no padding.

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 zero-param, no-output-schema tool, the description covers the trigger, the side effects, the idempotency guarantee, and the next step, which is nearly everything an agent needs. It stops short of stating required permissions or how to inspect the resulting watch list.

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?

The tool takes zero parameters, so the schema offers nothing to interpret and the baseline is 4. The description adds useful framing by clarifying that the seeded content is fixed and not caller-specified.

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 action (one-shot cold-start seed of the watch list) and exactly what it inserts: the July 18 fixture set on Base plus one live Polygon trading bot. This is clearly distinguishable from siblings like add_watch (single address) and list_watched (read), so an agent can tell them apart without opening schemas.

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?

Gives an explicit trigger condition ('Call this FIRST after connect when list_watched is empty') and the required follow-up call (get_dashboard). The empty-list precondition implicitly conveys when not to use it, but the obvious alternative for a non-empty list (add_watch) is never named.

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