data-contract

DE//AGENT currently lists 3 resources under data-contract: 1 tutorial, 1 skill, 1 template. Everything below is derived from the live registry — counts, capabilities, verification state and security posture come from the curated records, never from marketing copy.

Documented learning objectives across these resources:

• Specify a freshness and completeness SLA — via Data Contract Author
• Encode a contract as executable tests — via Data Contract Author
• Define a breaking-change policy consumers can rely on — via Data Contract Author
• Write all six parts of a contract for a real dataset — via Author your first data contract
• Specify freshness and completeness numbers in the SLA — via Author your first data contract
• Name the CI test that fails when the contract is violated — via Author your first data contract

These resources map to stage: Data Quality (3). Follow the four-phase roadmap to place this topic inside a progression instead of learning it in isolation.

Every entry, its shape and its trust state — sorted by the registry's composite score. This table is the honest version of a marketing comparison: no sponsored placements, no unverifiable claims.

How scores are computed: source quality score.

Highest composite score first:

1. Data Contract Author score 38.5 — intermediate
2. Author your first data contract score 34.15 — beginner
3. Data Contract Template score 33.1 — intermediate

Scores rank provenance, completeness and trust — read how verification works before adopting anything.

Security-flagged entries: Data Contract Author (1 flag), Data Contract Template (2 flags). Flags mean the record declares capabilities like credential use or write access — read the security posture on each page before connecting.

• Data Contract Author — Drafts a data contract (schema, semantics, freshness SLA, ownership, breaking- change policy) and the tests that enforce it in CI. details
• Author your first data contract — Draft an enforceable contract for one real dataset by walking the six parts — owner, schema, semantics, SLA, breaking-change policy, enforcement — starting from the data-contract t… details
• Data Contract Template — A contract skeleton (ownership, schema, semantics, SLA, compatibility policy) with the CI check that enforces it and a deprecation checklist. details
