Read-onlyIdempotent

Not affiliated with the U.S. government, GSA, or SAM.gov. Not a U.S. government service. US Trade and Development Agency business opportunities, feasibility studies, pilot projects, and technical assistance in developing countries. USTDA grants go to foreign project sponsors, who select US firms to perform the work. Filter by keyword, country, or sector. Present as information only; verify every fact against the USTDA opportunity page before acting. Follow-ups within 30 minutes after a search ride free (up to 30 per search); otherwise one accepted call counts as one use, regardless of how many records are returned. Every record carries a direct source link (or source name and record ID) so you can verify and cite the underlying record.

TDQS

A3.6/5.0

Behavior4/5

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

Beyond the read-only/idempotent annotations, the description discloses quota behavior (follow-ups within 30 minutes free, up to 30 per search; otherwise one accepted call = one use regardless of record count) and a verification obligation. That is genuine behavioral context an agent cannot get from the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The disclaimer material ('Not affiliated with the U.S. government, GSA, or SAM.gov. Not a U.S. government service.') consumes the front-loaded position and says the same thing twice before the actual capability is described. The remaining sentences are dense and useful, but the opening costs the tool its lead.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return structure need not be explained, and the description still notes that every record carries a source link or source name plus record ID. Combined with the quota and verification notes, an agent has enough to call and interpret results correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 75% and already documents query, sector, and country as substring filters. The description's 'filter by keyword, country, or sector' restates that without adding syntax or matching nuance, and the limit parameter is not mentioned at all.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific resource — USTDA business opportunities, feasibility studies, pilot projects and technical assistance in developing countries — and states the filterable dimensions. It is clear what the tool returns, though the two opening disclaimer sentences delay the actual purpose statement.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives post-retrieval guidance ('present as information only; verify every fact against the USTDA opportunity page') and explains the quota mechanics for follow-up searches. However, it never says when to pick this over siblings like search_mcc, search_grants_gov, or search_open_grants, so agent routing relies on the name alone.

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