Bug Report

Feature Area: Skills — Spec inconsistency in extensibility section vs skill schema

Issue Description

The spec's Extensibility section (lines 46390-46406) shows skill YAML files with a skill: top-level wrapper key and an agent_skills_dirs field:

# File: skills/kubernetes-ops.yaml
skill:
  name: local/kubernetes-ops
  description: "Kubernetes cluster management tools"
  mcp_servers:
    - transport: stdio
      command: npx
      args: ["-y", "@anthropic/mcp-kubernetes"]

And:

skill:
  name: local/project-tools
  agent_skills_dirs:
    - ./agent-skills/

Actual Schema (from spec and implementation)

The formal JSON Schema (spec line 32590) and the SkillConfigSchema implementation both define skill YAML files without a skill: wrapper:

# Correct format per JSON Schema
name: local/kubernetes-ops
description: "Kubernetes cluster management tools"
mcp_servers:
  - name: kubernetes
    transport: stdio
    command: npx
    args: ["-y", "@anthropic/mcp-kubernetes"]

Additionally, the extensibility section uses agent_skills_dirs but the schema uses agent_skill_folders.

Deviations Found

Extensibility Section	Formal Schema / Implementation	Status
`skill:` top-level wrapper	No wrapper (flat YAML)	❌ Inconsistent
`agent_skills_dirs` key	`agent_skill_folders` key	❌ Inconsistent
`mcp_servers` items without `name` field	`mcp_servers` items require `name` field	❌ Inconsistent

Impact

Users reading the extensibility section examples will write YAML files with skill: wrapper and agent_skills_dirs that will fail validation when passed to agents skill add --config
The SkillConfigSchema does not handle a skill: wrapper — it will raise a ValidationError with confusing messages about unexpected fields

Verification

from cleveragents.skills.schema import SkillConfigSchema

# This follows the extensibility section example but FAILS
yaml_with_wrapper = """
skill:
  name: local/kubernetes-ops
  description: "Kubernetes tools"
"""
SkillConfigSchema.from_yaml(yaml_with_wrapper)  # ValidationError: extra fields not permitted

Recommendation

The spec should be updated to make the extensibility section examples consistent with the formal JSON Schema. The skill: wrapper should be removed from the examples, and agent_skills_dirs should be corrected to agent_skill_folders.

Alternatively, if the skill: wrapper is intentional, the SkillConfigSchema.from_yaml method should be updated to unwrap it before validation.

Architect Assessment

This is a confirmed minor spec inconsistency. The Extensibility section examples (lines 46390-46406) are illustrative but don't match the formal JSON Schema defined in the Skill Configuration Files section (line 32590+).

Resolution direction: The formal JSON Schema is authoritative. The extensibility section examples should be updated to match:

Remove skill: wrapper — use flat YAML format matching the schema
Change agent_skills_dirs → agent_skill_folders to match the schema field name
Add name field to mcp_servers items as required by the schema

This is a minor documentation fix (examples alignment), not an architectural change. The implementer working on this issue should update the extensibility section examples to be consistent with the formal schema.

No architectural decision needed — the formal schema is correct and should not change.
