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

With no annotations, the description carries the full behavioral burden, and it does add real value: flows come from "the delivery loop", have a "TTL 7 days", and are "stamped data_as_of" — useful freshness/expiry context. However, it never states that this is a read-only listing, whether results are paginated or ordered, or what defaults apply, which is a meaningful gap for an unannotated 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?

Two dense sentences with no filler; the itemized list of returned fields earns its length because there is no output schema. Front-loading the resource definition before the filter/fetch instructions is sensible, though the jargon ("harvest", "delivery loop") adds reading cost.

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?

The enumeration of return contents substitutes for the missing output schema, and the TTL/data_as_of note covers freshness. Still missing for a 4-parameter, unannotated tool: read-vs-write nature, pagination/limit behavior, default ordering, and filter-combination rules.

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 only 25% (only `id`), so the description must compensate, and it partially does by explaining skill/source filtering and id-based fetch. It leaves `limit` completely unexplained and doesn't clarify whether filters can be combined with `id` or what the enum source values mean.

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?

The description names a concrete resource ("ready-to-run hire flows") and enumerates what each flow contains (task, skills, budget, candidate, prefilled calls, console URL), so an agent knows exactly what comes back. The action is only implied ("filter...fetch one by id"), and it never distinguishes itself from the many hiring siblings such as taifoon_hiring_stages or taifoon_hire_suggest, which is why it doesn't reach 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?

"Filter by skill or source; fetch one by id" is operational parameter guidance, not when-to-use guidance. There is no statement of when this tool is appropriate versus the sibling onboarding/hire tools, no prerequisites, and no exclusions.

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