Agent Skills: Concept Graph (prerequisites)

Concept Graph (prerequisites)

Goal: represent tutorial concepts as a prerequisite DAG so modules can be planned and ordered.

Inputs

• output/TUTORIAL_SPEC.md

Outputs

• outline/concept_graph.yml

Output schema (recommended)

A minimal, readable YAML schema:

• nodes: list of {id, title, summary}
• edges: list of {from, to} meaning from is a prerequisite of to

Constraints:

• Graph should be acyclic (DAG).
• Prefer 10–30 nodes for a medium tutorial.

Workflow

1. Read output/TUTORIAL_SPEC.md and extract the concept list implied by objectives + running example.
2. Normalize each concept into a node with a stable id.
3. Add prerequisite edges and verify the graph is acyclic.
4. Write outline/concept_graph.yml.

Definition of Done

• [ ] outline/concept_graph.yml exists and is a DAG.
• [ ] Nodes cover all learning objectives from output/TUTORIAL_SPEC.md.
• [ ] Node titles are specific (not “misc”).

Troubleshooting

Issue: the graph looks like a linear list

Fix:

• Add intermediate prerequisites explicitly (e.g., “data model” before “evaluation protocol”).

Issue: cycles appear (A → B → A)

Fix:

• Split concepts or redefine edges so prerequisites flow in one direction.
