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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety and locality are covered. The description adds useful provenance — the content mirrors iomarkets.org/roadmap — implying a static snapshot rather than live data, though it never says whether that snapshot can be stale. No auth, rate-limit, or response-shape details are given, which is acceptable given the annotation coverage.

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?

One sentence, front-loaded with the content ('what has been built and is building next') followed by the provenance qualifier. Nothing is wasted and nothing important is buried.

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?

With no parameters, no output schema, and read-only annotations, the description's main burden is telling the agent what comes back — and 'in the same words as iomarkets.org/roadmap' does that better than most. It stops short of saying the return format (text, markdown, link) or whether the roadmap is time-stamped.

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 there is nothing for the description to disambiguate; the baseline for a no-param tool applies. Nothing in the description contradicts or complicates the empty 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?

States the resource precisely: the company's roadmap, both shipped and planned items. The phrase 'in the same words as iomarkets.org/roadmap' pins down the exact content an agent will receive, which is more specific than a bare 'get roadmap'. It does not, however, explicitly contrast itself with nearby siblings such as get_overview or get_guide.

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?

There is no statement of when to call this versus get_overview, get_guide, or get_sample, all of which could plausibly answer 'what is this company about'. No prerequisites, no exclusions, no context beyond the content itself. The agent must infer that this is the right tool for roadmap questions.

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