Cf Split

Evaluate or execute a behavior-preserving file-level split from one source file into nearby owned files. Use when the current request asks whether a file should be split or asks to perform a scoped extraction into files. Route regrouping of multiple related files to cf-cohesion and repository-level restructuring to cf-start.

File contents

Use this skill for local file-level split review and execution.

Use this when the current request asks whether a source file should be split into files, or asks to execute a specific local file-level extraction. Do not use this for cognitive cleanup inside one file; use cf-cognitive for that. Do not use this for regrouping already-split related files; use cf-cohesion for that. For repository structure, module boundaries, cross-feature ownership moves, or broad multi-file refactors, route to cf-start.

Do not bootstrap or require .cflow/ artifacts.

Preflight

Identify one target source file or one explicitly touched local file area.
If the target, flow, or requested outcome is ambiguous, ask one focused question.

Flow Selection

Choose exactly one flow: Evaluation flow does not edit repository files.

Evaluation Flow

Use when the current request asks whether a split is worthwhile. Read references/evaluation.md, references/file-split-rules.md, and references/navigation-cost.md.

Execution Flow

Use when the current request explicitly asks to perform the split. Read references/execution.md, references/file-split-rules.md, references/navigation-cost.md, and references/reference-audit.md. If a verification check fails, read references/regression-handling.md.

Do not infer execution from words like "review", "check", "is this worth splitting", or "should this be extracted".

Output Format

Return only:

Scope: target file and selected flow.
Decision: candidates and recommendation, or split performed.
Checks: commands run and pass/fail result, or why no check ran.
Deferred: only after execution edits; findings required by the report/action rule in references/navigation-cost.md. Omit this section when no split ran and in evaluation.
Result: behavior preservation, final placement decision, remaining risk, and next action.
