Contracts nearing end date

list_awards_by_period_end

Read-onlyIdempotent

Not affiliated with the U.S. government, GSA, or SAM.gov. Not a U.S. government service. Lists public award records in GovInbox's database whose recorded period-of-performance end dates fall within the requested lookahead window. Dates are reported source facts, and unexercised options or later modifications may change them. These are award records, not open solicitations; an ending performance period does not predict a new solicitation. GovInbox does not return model estimates through these tools. Does not recommend bids, determine eligibility, or suggest partners. 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 the number of records returned. Every record carries a direct source link (or source name and record ID) so you can verify and cite the underlying record. Without a connected GovInbox account, both limits apply: 3 searches per UTC calendar day and 10 per UTC calendar month. With a connected GovInbox account, the limit is 20 searches per UTC calendar month, with no separate daily limit. One accepted search counts as one use, regardless of the number of records returned. Follow-up calls (opening records, comparing versions, listing awards or subawards) within 30 minutes after a search do not count extra, up to 30 follow-ups per search. A follow-up invoked with no active search window counts as one use and opens a new 30-minute window. Empty results consume the search. A lookup for a record that does not exist is not charged. Each retry of a search counts as a new search, as does each call for another page of search results. Daily limits reset at 00:00 UTC each day; monthly limits reset at 00:00 UTC on the first day of each month. Requests rejected for invalid authentication or an exhausted quota do not consume a use.

TDQS

B3.4/5.0

Behavior5/5

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

Beyond the readOnly/openWorld/idempotent annotations, the description discloses billing and quota mechanics in detail: per-search charges, free follow-up windows, empty-result charging, retry and page charging, reset times, and uncharged failed lookups. It also flags data provenance caveats and explicitly says no model estimates are returned.

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

Conciseness2/5

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

The definition is long and repetitive, restating the 30-minute follow-up window and 'one accepted search counts as one use' multiple times. Legal disclaimers lead the description, pushing the actual purpose into the second sentence.

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

Completeness3/5

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

The description is rich on billing, data caveats, and safety context, and an output schema covers return shape. However, for a six-parameter tool with only 67% schema-description coverage, it omits how the filters work and gives no alternative-tool routing, leaving gaps an agent must infer.

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

Parameters2/5

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

Schema description coverage is 67%, and the description adds no parameter-level guidance beyond the phrase 'lookahead window' for lookahead_months. It never explains that naics is required or how geography, certifications, limit, and cursor shape the result.

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 first substantive sentence names a specific verb (Lists) and resource (public award records) and scopes it to period-of-performance end dates within the lookahead window. It also draws a clear boundary against open solicitations, though it does not name specific sibling tools for related award or recompete queries.

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?

The usage is implied by the purpose: finding awards with performance periods ending in a window. It also warns these are not open solicitations, which helps prevent misuse, but it never names alternatives like open-notice searches or recompete tools, nor states when a different award-search tool is preferable.

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