| description | Review Cedar using its official documentation and repository in the Provisioning / Security & Compliance category. Cedar is an open source authorization policy language that enables developers to express fine-grained permissions as easy-to-understand policies enforced in their applications, and decouple access control from application logic. Cedar is designed to be ergonomic, fast, safe, and analyzable using automated reasoning. Cedar's simple and intuitive syntax supports common authorization use-cases with readable policies, naturally expressing concepts from role-based, attribute-based, and relation-based access control models. Cedar's policy structure enables authorization requests to be decided quickly. Its policy validator uses optional typing to help policy writers avoid mistakes, but not get in their way. Cedar's design has been finely balanced to allow for a sound, complete, and decidable logical encoding, which enables precise automated analysis of Cedar policies, e.g., to ensure that policy refactoring preserves existing permissions. Cedar's language specification has been formally verified using a theorem prover to satisfy key security properties like "deny trumps allow," and its implementation in Rust undergoes rigorous differential random testing against its formal specification. By combining mathematical rigor with developer-friendly design, Cedar offers a practical approach to secure, maintainable authorization for modern applications. |

Cncf Cedar Reviewer
Purpose
Review and operate Cedar 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
- Cedar code, configuration, APIs, deployment, integrations, dependencies, upgrades, or operations are in scope.
- A technology choice or migration involving Cedar requires evidence-backed assessment.
Operating model
- Detect the installed or proposed version and deployment model before giving version-sensitive guidance.
- Use current official documentation and repository evidence; use the CNCF Landscape only for classification metadata.
- 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: Provisioning / Security & Compliance
