Included Skills8

agent-prompt-standardsskills/agent-prompt-standards/SKILL.md

Agent prompt writing conventions enforced across all creator and auditor skills. Loaded by other skills, not invoked directly.

audit-skillskills/audit-skill/SKILL.md

SKILL.md audit methodology — judges skill content for standards compliance, operational effectiveness, portability, voice, and structure.

audit-subagentskills/audit-subagent/SKILL.md

Subagent-configuration audit methodology — judges a subagent configuration file against the subagent and agent-prompt standards, covering frontmatter, role framing, constraints, and output contract.

create-skillskills/create-skill/SKILL.md

ALWAYS invoke this skill when creating, editing, or improving SKILL.md files or bundled workflows, references, templates, and scripts; explaining skill patterns; or verifying that skill content is current.

create-subagentskills/create-subagent/SKILL.md

ALWAYS invoke this skill when creating, editing, or configuring subagents. NEVER create subagents without this skill.

instructions-pluginskills/instructions-plugin/SKILL.md

ALWAYS invoke this skill to operate the instructions plugin's own lifecycle — report its version and check or reconcile its agent-delivery footprint. Invoke it when this plugin's agents are missing from a session. NEVER commit marketplace-delivered agent definitions into a checkout.

Skill authoring standards enforced across all creating and auditing skills. Loaded by other skills, not invoked directly.
