APA 5 U.S.C. § 553 Regulatory Docket Comment Letter Synthesizer

synthesize_regulatory_docket
Read-onlyIdempotent

Drafts a formal Administrative Procedure Act (APA, 5 U.S.C. § 553) Public Comment Letter cited with empirical Ariadne Nexus FINRA TRACE G-SIB spread and x402 OFAC SDN screening telemetry for active Federal Reserve/OFR, FinCEN/OFAC, SEC DERA, or FSOC rulemaking dockets. Use when: preparing a statutory public comment submission or empirical policy memorandum for a specific federal financial regulatory docket (FED_TREASURY_OFR, FINCEN_OFAC_X402, SEC_DERA_TRACE, or FSOC_NONBANK_CONTAGION). Do not use when: reading the weekly macro-prudential policy monitor (use get_sovereign_policy_brief instead) or screening an entity against OFAC sanctions lists (use screen_ofac_entity instead). Behavior: Read-only local document synthesis ($2.50 USD per call via apiKey or paymentToken). Does NOT automatically transmit or file comments with regulations.gov or any external agency; returns the structured comment text and cryptographic SHA-256 citation hash for human review.

TDQS

A4.6/5.0
Behavior5/5

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

Although annotations already declare readOnly/idempotent/non-destructive and a closed-world local tool, the description adds value beyond them: per-call pricing ($2.50 via apiKey or paymentToken), and the critical fact that it does NOT transmit or file with regulations.gov, returning only structured text plus a SHA-256 citation hash for human review. That is exactly the kind of side-effect disclosure an agent needs for a 'synthesis' tool.

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

Conciseness4/5

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

Front-loaded with the tool's identity, then cleanly partitioned into Use when / Do not use when / Behavior. It is dense with domain jargon and long as a single block, but nearly every clause carries routing or behavioral information rather than filler.

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?

With an output schema present, the description needn't explain return values, and it still covers the essentials: target dockets, auth/payment paths, and the no-external-filing constraint. Nothing an agent needs to call this correctly is missing.

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 schema already documents all six parameters, their defaults, and the agency_id enum. The description restates the docket identifiers and mentions apiKey/paymentToken but adds no syntax or format detail beyond the schema. Baseline 3 applies when the schema does the heavy lifting.

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?

States a specific verb+resource (drafts an APA § 553 public comment letter) and a precise domain (Fed/OFR, FinCEN/OFAC, SEC DERA, FSOC dockets). It explicitly distinguishes itself from siblings by naming get_sovereign_policy_brief and screen_ofac_entity, so an agent can disambiguate without opening schemas.

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

Usage Guidelines5/5

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

Contains explicit 'Use when' and 'Do not use when' clauses, each routing to a named alternative (get_sovereign_policy_brief for the weekly monitor, screen_ofac_entity for sanctions screening). The condition that selects this tool (preparing a statutory comment submission for a specific docket) is unambiguous.

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