Verified Knowledge
Citation-backed compliance knowledge an agent can prove, not just recall.
Most agents answer compliance questions from a model's memory — confidently, and sometimes wrong. Stacklink's knowledge packs replace that: every answer traces to an exact quote from an official source, currently in force, with a receipt you can show a user or a regulator.
No general agent platform offers this. If your product touches tax, regulation, or law, it's the reason to build on Stacklink.
What you do
Enable a pack on the session, then use one of two surfaces:
const session = await stacklink.create({
tenantId, userId,
knowledgePacks: { enable: ['in.business_compliance.authority'] },
});
// 1. Prose questions — search, then verify before you answer
const hits = await session.searchKnowledge({ query: 'GSTR-1 late fee for a nil return' });
const check = await session.verifyKnowledgeAnswer({
evidenceIds: hits.results.map((r) => r.evidence.evidenceId),
});
// 2. Calculations — deterministic, never inferred
const due = await session.calculateGstDueDate({ formKey: 'gstr1', periodEnd: '2024-11-30' });Over MCP these are the KNOWLEDGE_* and GST_* tools — the agent calls them the same way.
What you get back
Every result carries an evidence receipt — the thing that turns "the model said so" into "here is the exact clause, from this source, currently in force." Three guarantees:
- Cited — an exact quote plus a link to the official source.
- Current — superseded or expired rules are excluded by default (fail-closed).
- Verifiable — re-check any answer with
verifyKnowledgeAnswer; the check is deterministic, not a model's opinion.
Two ways to use a pack
Evidence receipts
Search prose, cite exact quotes, and verify the answer before you present it.
Structured tools
Deterministic calculations (GST due dates, late fees, rates) — each backed by evidence links.
Curious how packs are built (sources, blocks, releases, amendment trails, hybrid retrieval)? That's the data model — see How packs work.
