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:

Ask, then verify
const session = await stacklink.create({
  tenantId, userId,
  knowledgePacks: { enable: ['in.business_compliance.authority'] },
});

// 1. Prose questionssearch, 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  • Current — superseded or expired rules are excluded by default (fail-closed).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

Curious how packs are built (sources, blocks, releases, amendment trails, hybrid retrieval)? That's the data model — see How packs work.
