How to read this: tool names here are observed from a live tools/list handshake. The Risk label is a heuristic inferred from the tool name (write/destructive verbs), not from executing the tool — a conservative guess, not a verified capability. We never escalate risk from a description. Found one that's wrong? Tell us — we fix on report.
| Tool | Risk | Side effects | Approval |
|---|---|---|---|
| get_provision_history Documented change history for a CFR provision by canonical id (e.g. "21-cfr-1304.04(a)"): before/after text, computed redline, observed dates, and candidate final rules. 404 when the provision is not in the documented-change set — absence of a documented change is not a claim that nothing changed. No API key required. | read | false | unknown |
| get_requirement Detail for one extracted obligation by id, including its source rule and citation URL. Requires an API key. | read | false | unknown |
| get_rule_comments Public comments for a Federal Register document (organization, title, date, body where available). Coverage is partial and stated in the response. Requires an API key. | read | false | unknown |
| get_stats Aggregate corpus statistics: documents, obligations, pairs, agencies, coverage dates. No API key required. | read | false | unknown |
| list_obligations List extracted regulatory obligations ("who must do what") with filters: agency, deontic class, free text. Obligations are machine-extracted with quality tiers; they are not legal advice. Requires an API key. | read | false | unknown |
| list_rules List Federal Register documents with filters: agency slug, document type, rulemaking pathway (interim_final/temporary/direct_final = notice-and-comment bypass classes), or docket id. Requires an API key. | read | false | unknown |
| lookup_provision Look up a CFR provision by citation (e.g. "21 CFR 1304.04") or by an exact quotation, optionally as of a past date. Returns the provision text with a ProvisionEvidence object (source, snapshot date, hashes). Explicitly reports ambiguity or no-match instead of guessing. Requires a free API key. | read | false | unknown |
| recent_cfr_changes Most recent detected changes to CFR text (title, part, name, dates), newest first. No API key required. | unknown | unknown | unknown |
| search_regulations Full-text search over Federal Register documents and extracted obligations (FTS5/BM25). Totals are approximate (total_exact: false). Requires an API key. | read | false | unknown |
