When to Use

• Use when this upstream workflow matches the user's stated goal.
• Use when the task requires the procedures documented in this skill.

Codebase Onboarding

Use this skill when the user asks for codebase onboarding using Ontoly evidence.

Required Workflow

Follow [the shared Ontoly workflow. Also read [graph evidence rules, [MCP usage, [best practices, and [fallback rules when the task requires detail.

Ontoly Capabilities

Use these capabilities first: ExplainArchitecture, FindEntrypoints, GraphStatistics, FindFeatureOwner, EvidencePack.

Output Contract

Return:

• answer or plan
• capabilities invoked
• graph evidence with node ids, edge types, source spans, and graph hash when available
• confidence: high, medium, or low
• fallback reason if repository files were inspected

Boundaries

Do not implement compiler, query, MCP, SDK, or business logic in the skill. Do not search repository files until Ontoly cannot answer or evidence must be confirmed.
