Event data quality

The contract between agents producing and consuming your event data.

Inferred from what actually landed in your warehouse, served over MCP, verified daily. Never written to your repository.

How it works

Landed data is the truth.

Detect

One contract per event, inferred from what landed. Nobody types a schema.

required · null rate under 1% over 30 days

Enforce

Agents read the active contract over MCP before they write tracking.

get_contract · check_payload · propose_change

Monitor

Landed rows are diffed against the contract daily. Each difference is one proposal.

property absent for a day · type changed · new event

Resolve

Accept, reject or snooze. Accepting versions the contract and tells every consumer.

accept · reject · snooze for seven days

Over MCP

What your agents read.

suky calls no model of its own. It serves facts; your agents do the reasoning.

The warehouse is the judge.

What landed is the truth. Your CDP's schema is an input.

Nobody authors a contract.

Inferred first, then confirmed and versioned by people and agents.

Read-only and published.

Every query is committed verbatim. suky keeps schema-level stats, never a row.

Never writes to your repository.

No commits, no pull requests. Your agents make the code change.
