echo_facility_report

Read-only

Fetch a facility's EPA ECHO compliance, enforcement, inspection, and permit history by RegistryID for due diligence.

Instructions

Fetch the EPA ECHO Detailed Facility Report (DFR) for ONE facility by its FRS RegistryID (keyless) — the per-facility compliance / enforcement / inspection / permit deep-dive for competitor or acquisition-target due diligence. Input registryId (the RegistryID exactly as returned by echo_search_facilities rows — usually a 12-digit FRS id, but ECHO also returns state/program ids like 'DCR000509282' and short ids like '9434', all accepted; 1–20 letters/digits). Returns { registryId, report:{…verbatim compliance/enforcement/permit detail…} } + single-record _meta (complete:true, no pagination). A bad/unknown RegistryID ⇒ not_found (never a fabricated report).

A4.5/5.0
Behavior5/5

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

Annotations already signal readOnlyHint=true and openWorldHint=true, and the description adds meaningful behavioral detail: keyless access, accepted ID formats, exact return shape (registryId + report + _meta with complete:true and no pagination), and a clear not_found error guarantee with no fabricated reports. This goes well beyond structured fields.

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

Conciseness5/5

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

The description is dense but well-structured: purpose, input requirement, return shape, and error behavior are covered in four purposeful sentences. Every sentence earns its place, and the most decision-relevant details (single facility, RegistryID, not_found guarantee) are front-loaded.

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

Completeness5/5

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

Despite no output schema, the description specifies the return envelope, the verbatim report content, metadata behavior, pagination absence, and error semantics. For a single-parameter tool with full schema coverage enough context is provided for an agent to invoke it correctly and interpret results.

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 description coverage is 100%, so the baseline is 3. The parameter semantics are fully captured in the schema, and the description repeats the same format constraints and error behavior without adding materially new information about the parameter beyond what the schema already provides.

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

Purpose5/5

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

The description uses a specific verb ('Fetch') and resource ('EPA ECHO Detailed Facility Report') for exactly one facility by RegistryID. It clearly frames the report as a compliance/enforcement/inspection/permit deep-dive, distinguishing it from the sibling echo_search_facilities which is for discovery rather than report retrieval.

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

Usage Guidelines4/5

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

It states the tool is for one facility and explicitly ties the input to values 'exactly as returned by echo_search_facilities rows', which implies search-then-report workflow. It does not name an alternative explicitly, but the sibling relationship and one-facility scope provide adequate usage context.

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