trmnl_list_flash_firmwares

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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, so the safety profile is covered. The description adds useful context about the data source and meaning (builds flashable via the /flash web flasher, backed by GET /api/firmware/flash), but says nothing about result size, ordering, or pagination.

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 lines with the core purpose front-loaded; nothing is padded. The raw endpoint line is marginal but plausibly useful for agents correlating with the underlying API.

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?

A simple read-only catalog lookup with full annotation coverage, a fully documented single parameter, and no output schema to explain. The description is sufficient for correct invocation, with only return shape/pagination left implicit.

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% and the single 'profile' parameter is already documented as a configured profile name defaulting to 'default'. The description adds no further semantics about what the profile selects or how it affects the returned firmware list, so the baseline 3 applies.

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: lists flashable firmware versions, scoped per device model. The added note that these are the builds usable via the TRMNL web flasher (/flash) sharpens the concept. It does not name a sibling (e.g. trmnl_list_models) to distinguish itself, so it stops short of a 5.

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?

Usage is only implied: an agent can infer this is for looking up which firmware can be flashed on a given model, but the description never says when to call it, when not to, or how it relates to adjacent tools like trmnl_list_models or trmnl_retry_device_firmware_update.

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