Files found in the same public projects as a version of this one, more often than they turn up anywhere else. Each project counts once, large collections count for less, and this file's own repository is left out.
Microsoft AzureSkillrelease-notes
Author and update release notes for Azure App Configuration libraries and providers. USE FOR: write release notes, add release note entry, update release notes, draft release notes, new version release notes, format release notes. DO NOT USE FOR: generating changelogs from git history, writing internal engineering notes.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
1 rule. 0 are common, 0 are distinctive, and 1 is very specific to this project.
0
Common
Most of the 9 edited versions we read keep these.
0
Distinctive
This author's own choices. Worth a look.
1
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common

Breaking Change Detection: Run oasdiff or openapi-diff in CI/CD to block backward-incompatible changes (e.g.
“Common” is measured: kept by at least 6 in 10 of the 9 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Contract Testing & OpenAPI Validation Skill
This skill ensures microservices communicate reliably via explicit, version-controlled contracts without breaking downstream consumers.
Core Architectural Pillars
1. OpenAPI & Schema Drift Validation
- Spec-First & Code-First Sync: Enforce strict TypeScript/Zod/JSON Schema generation from OpenAPI 3.1 definitions.
- Breaking Change Detection: Run
oasdifforopenapi-diffin CI/CD to block backward-incompatible changes (e.g. removed fields, altered types, tightened validation).
2. Consumer-Driven Contract Testing (Pact)
- Consumer Contracts: Downstream microservices define expected API requests and responses.
- Provider Verification: Upstream microservice verifies actual endpoint execution against consumer expectations before deployment.
- Pact Broker Matrix: Track deployment status across environments to prevent deploying incompatible service versions.
3. Mock Service Worker (MSW) & Integration Mocks
- Deterministic API Fixtures: Shared MSW handlers across unit, component, and E2E tests.
- Network Level Interception: Mock API traffic at network level to avoid fragile global fetch overrides.
Checklist for Slices with needs_contract_testing: true
- OpenAPI 3.1 schema defined or updated
- Breaking change check passes against
mainbranch schema - Consumer Pact tests generated or MSW handlers synchronized
- Provider endpoint verification passes end-to-end

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
