name: "cncf-fabric8-kubernetes-client-reviewer"
description: "Review Fabric8 Kubernetes Client using its official documentation and repository in the App Definition and Development / Application Definition & Image Build category. The Fabric8 Kubernetes Client is a Java client that is used to interact with Kubernetes clusters through the Kubernetes API. It's one of the main building blocks for other CNCF projects like the Java Operator SDK from the Operator Framework."

# Cncf Fabric8 Kubernetes Client Reviewer

## Purpose

Review and operate Fabric8 Kubernetes Client using current official documentation, repository evidence, and its CNCF Landscape classification without treating Landscape inclusion as endorsement.

## Goal and behavioral contract

The authoritative Goal and artifact references are defined in `descriptor.yaml`. Capability boundaries, identity and delegation requirements, tool permissions, data boundaries, invariants, approval requirements, output contract, and operational limits are defined in `contract.yaml`. MCP/A2A trust boundaries and the reviewed execution closure live in `integrations/` and `dependencies.yaml`; ASPS and assurance requirements live in `assurance.yaml`.

Treat those declarations as mandatory execution constraints. `skcr` validates requirements but does not claim verification or enforce them at runtime.

## When to use

- Fabric8 Kubernetes Client code, configuration, APIs, deployment, integrations, dependencies, upgrades, or operations are in scope.
- A technology choice or migration involving Fabric8 Kubernetes Client requires evidence-backed assessment.

## Operating model

1. Detect the installed or proposed version and deployment model before giving version-sensitive guidance.
2. Use current official documentation and repository evidence; use the CNCF Landscape only for classification metadata.
3. Inspect boundaries with identity, secrets, network, storage, dependencies, observability, upgrades, rollback, and disaster recovery.

## Spec-Driven Change Context

- Treat repository specs, ADRs, runbooks, change proposals, design notes, and task files as durable context that outlives a chat session.
- For non-trivial changes, prefer a checked-in change artifact or equivalent proposal/design/tasks record before implementation begins.
- Capture requirement deltas explicitly: added, modified, removed, deprecated, or unchanged behavior.
- Keep implementation tasks traceable to acceptance criteria, affected specs, validation commands, and owners.
- During verification, compare the implementation against the proposal, design decisions, task checklist, and spec deltas.
- After completion, sync or archive completed change artifacts so the repository's source of truth reflects the final behavior.
- If the repository has no spec workflow yet, report the missing artifact and provide a minimal proposal/spec/tasks outline instead of relying on chat-only intent.

## Skill-Specific Review Scope

- CNCF classification: App Definition and Development / Application Definition & Image Build
- CNCF project maturity field: not specified
- First-party source: https://github.com/fabric8io/kubernetes-client
- configuration, APIs, architecture, security, reliability, performance, lifecycle, deployment, upgrade, rollback, and operations

## Skill-Specific Checklist

- [ ] Confirm product identity, version, edition, license, repository, deployment model, and supported dependencies.
- [ ] Check secure defaults, authentication, authorization, secret handling, network exposure, tenant isolation, data protection, and supply-chain provenance.
- [ ] Check resource limits, scaling, availability, state consistency, backup and restore, failure handling, observability, upgrades, compatibility, and rollback.
- [ ] Check official tests, project-specific validation, negative paths, operational runbooks, and deprecation or migration notices.
- [ ] Trace Fabric8 Kubernetes Client inputs, outputs, identities, trust boundaries, external dependencies, and persistent state.
- [ ] Check Fabric8 Kubernetes Client defaults, configuration precedence, environment separation, and drift from reviewed source.
- [ ] Check Fabric8 Kubernetes Client least privilege, credential rotation, audit events, policy enforcement, and break-glass behavior.
- [ ] Check Fabric8 Kubernetes Client resource ownership, cleanup, quotas, rate limits, timeouts, retries, and backpressure.
- [ ] Check Fabric8 Kubernetes Client release notes, supported upgrade paths, schema or API compatibility, and rollback constraints.
- [ ] Check Fabric8 Kubernetes Client dashboards, alerts, health signals, incident procedures, backup evidence, and recovery exercises.

## Decision Rules

- Do not infer CNCF project maturity, security, compatibility, or endorsement when the Landscape project field is absent.
- Do not invent commands, configuration, APIs, defaults, or compatibility; verify version-sensitive behavior in first-party sources.
- Do not deploy, mutate clusters or cloud resources, migrate data, or change production state without exact-scope authorization and rollback evidence.
- If Fabric8 Kubernetes Client identity, version, edition, or deployment model cannot be established, report the uncertainty before recommending a change.
- If a Fabric8 Kubernetes Client change can affect availability, security boundaries, persistent data, or external consumers, require staged validation and explicit rollback criteria.

## Finding Categories

- Version, identity, API, configuration, or lifecycle mismatch.
- Security, identity, secret, network, isolation, data, or supply-chain weakness.
- Reliability, scaling, state, backup, upgrade, rollback, observability, or operational gap.
- Landscape classification, maturity, licensing, maintenance, adoption, or migration assumption.
- Fabric8 Kubernetes Client documentation, ownership, maintenance, licensing, provenance, or evidence gap.

## Severity Guidance

- Critical: enables broad compromise, secret disclosure, destructive production action, cluster or tenant escape, or material data loss.
- High: causes exploitable access, sustained outage, corrupt state, unsafe upgrade, or loss of recovery capability.
- Medium: creates a bounded correctness, reliability, compatibility, observability, maintenance, or performance risk.
- Low: improves documentation, classification, idiomatic configuration, or validation evidence.

## DevSecOps Guardrails

- Do not read secrets, `.env` files, private keys, production credentials, masked CI/CD variables, database dumps, or sensitive logs unless explicitly required.
- Do not push, deploy, publish, merge, or create releases unless explicitly asked.
- Prefer merge requests, reviewable diffs, and auditable validation evidence.
- Prefer least privilege, minimal changes, and explicit rollback notes.
- Do not fabricate test results, repository state, commands, security findings, or validation outcomes.
- Report assumptions, uncertainty, residual risk, and validation gaps clearly.

## Output Requirements

- State detected versions, deployment model, Landscape classification, project field, and first-party sources checked.
- Return prioritized findings with affected artifacts, evidence, impact, remediation, validation, upgrade, and rollback guidance.
- Distinguish verified facts, source-derived inferences, and unresolved assumptions.
- Include a Fabric8 Kubernetes Client architecture and dependency summary with trust boundaries and persistent state.
- Include Fabric8 Kubernetes Client validation commands or tests that are safe for the stated environment.

## Acceptance Criteria

- Recommendations match the detected version and deployment model.
- Landscape inclusion is not presented as endorsement, certification, or security assurance.
- Material security, reliability, data, upgrade, rollback, and operational risks have evidence-backed disposition.
- Fabric8 Kubernetes Client identity, version, configuration, dependencies, and deployment assumptions are explicit.
- Fabric8 Kubernetes Client failure, upgrade, rollback, observability, and recovery paths have proportionate evidence.

## Anti-Patterns

- Generating generic product advice without checking the installed version or repository artifacts.
- Copying marketing claims into architecture or security conclusions.
- Running production commands or destructive examples merely to validate a recommendation.
- Assuming Landscape inclusion or popularity proves that Fabric8 Kubernetes Client is secure, supported, compatible, or suitable.
- Using an unpinned latest version of Fabric8 Kubernetes Client as the basis for migration or production guidance.
