plugins/kronen/skills/file-ownership/SKILL.md
Decompose a feature into parallel development streams with strict file boundary ownership. Each stream owns specific files exclusively; interface contracts are defined at boundaries before implementation begins. Prevents merge conflicts structurally. Use when decomposing a feature for parallel agent execution, when planning a wave where multiple agents will work simultaneously, when a previous parallel attempt produced merge conflicts, or when a multi-stream plan needs explicit ownership assignments to prevent write contention.

- Adapted file-boundary decomposition methodology to kronen plan-engine integration. Added ownership.yml schema and interface contract pattern.
file-ownership
Assign strict file ownership before parallel dispatch. No shared files. Interface contracts at boundaries. Prevents merge conflicts structurally.
Core Rule
One stream, one file. No file owned by two streams.
If two streams both need to write the same file, either:
- Assign it to one stream and expose the result as a read-only interface
- Split the file into two files owned by separate streams
- Make it a third stream that both depend on (sequential dependency)
Decomposition Steps
1. List all files that will be created or modified
2. Identify natural boundaries (module, layer, feature slice)
3. Assign each file to exactly one stream
4. For each cross-stream dependency: write the interface contract
5. Write ownership.yml
6. Dispatch streams with their ownership list in the prompt
Full Process
See references/process.md for ownership.yml schema, interface contract
format, boundary detection heuristics, and conflict resolution rules.
