Apache Avro

DE//AGENT currently lists 2 resources under Apache Avro: 2 skills. 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:

• Apply backward/forward compatibility rules to a diff — via Schema Change Contract Review
• Detect a breaking change hidden behind a "safe" rename — via Schema Change Contract Review
• Write a deprecation plan with dates — via Schema Change Contract Review
• 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

These resources map to stage: Data Quality (2). 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. Schema Change Contract Review score 40.5 — intermediate
2. Data Contract Author score 38.5 — intermediate

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

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

• Schema Change Contract Review — Diffs an old and new schema, classifies the change (compatible / risky / breaking) against consumers, and produces the migration and comms plan. details
• Data Contract Author — Drafts a data contract (schema, semantics, freshness SLA, ownership, breaking- change policy) and the tests that enforce it in CI. details

Real install commands from the registry — read the source before running any of them:

npx de-agent-platform add schema-change-contract-review

Schema Change Contract Review — review first

npx de-agent-platform add data-contract-author

Data Contract Author — review first
