5. Dimension Breakdown

Dimension 1: Open Standard Manifest Conformance (plugin.json)

Validates that plugin.json adheres to the Agent Plugins v1.0.0 closed specification with valid JSON syntax, SemVer versioning, no illegal inline component definitions, reverse-domain extension naming, and verified extension path resolutions.

Dimension 2: MCP Connection Layer Conformance (mcp.json)

Audits mcp.json for valid JSON syntax, explicit type declarations on all server entries (stdio, streamable-http, sse), zero hardcoded plaintext credentials, and strict filesystem containment within the plugin root.

Dimension 3: Skills & Domain Knowledge Conformance (skills/)

Ensures procedural workflows (skills/<name>/SKILL.md) provide actionable automation for project-specific operations, verifying that capability descriptions avoid generic dummy placeholders and include scripts/, references/, and optional assets/.

Dimension 4: Constitutional Safety & Hook Enforcement (com.<client>.client/hooks/)

Verifies that hook scripts are executable (chmod +x), pass syntax validation, and enforce non-negotiable negative invariants (blocking destructive file or database mutations).

Dimension 5: Specialist Subagent Persona Quality (custom-agent/ or plugins/)

Ensures specialist personas have bounded system prompts defining explicit roles, allowed tools, and forbidden operations to prevent context rot and unauthorized actions.

Dimension 6: Least-Privilege Permissions & Documentation (docs/)

Audits docs/permissions.md and docs/agent-extension-pack.md to guarantee clear least-privilege boundaries and comprehensive operator documentation.

Dimension 7: Zoomcamp Module 5 & Interactive Demo Verification (docs/demo.md)

Confirms full satisfaction of all 7 minimum deliverable requirements, presence of docs/demo.md outlining the 6-step interactive demonstration, and presence of companion documentation (mcp-server/README.md, custom-agent/README.md).
