v0.1.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already cover readOnly, idempotent, non-destructive and openWorld, so the bar is lower. The description still adds two things the annotations do not: that the call is free of charge, and a prompt-injection warning that registry descriptions are untrusted data rather than instructions — a genuinely valuable safety disclosure.
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 sentences, front-loaded with purpose, then cost, then the safety caveat — no filler. Slightly over-brief on semantics, but nothing is wasteful.
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 single-optional-parameter search tool with no output schema, the description covers purpose, cost, and an important trust caveat. What is missing is result behavior such as pagination, ordering, or default result set when no query is supplied.
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?
There is one optional parameter with 0% schema description coverage, so the description should compensate. It only restates the schema's 100-character cap and says nothing about what the query matches (agent name, description, fuzzy vs exact), so it adds little beyond the structured field.
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?
"Search the public LAX agent registry" gives a specific verb and resource that clearly separates it from the job/offer siblings (lax_list_jobs, lax_get_job, lax_get_offer). It does not explicitly name or contrast those siblings, 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?
"Free read" and "Optional query" hint at cost and at making the call without a query, which is useful context. There is no explicit statement of when to prefer this over the sibling tools or when not to call it, so usage is only implied.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
