CCF Project Scaffolder

Family File Contract

Before file work, reuse canonical paths and one task/artifact working directory; default to project-root ccfa-workfiles/<purpose>/<artifact-id>/. Update in place, preserve inputs, and use UTF-8 with Chinese-text checks. Apply artifact-contracts.md for naming, ownership, and task-created cleanup; handoffs inherit these paths.

Collaboration Contract

Before specialist execution, read and apply ccf-humanization first, then ccf-common. At every handoff, reuse their applicable active rules or refresh missing/changed ones. Both preflights are required even without prose; detailed editing, experiment, and maintenance modes run only when relevant.

Integrate necessary specialist contributions under one owner; reuse valid prerequisites and verify affected results. Follow the cooperation routes without duplicate reports.

Invocation Controls

CCFA Handoff Mode: PARTIAL (Recommended). Follow metadata.ccf_skill_controls.handoff_question_mode, ../ccf-common/references/handoff-modes.md, and ../ccf-common/references/task-modes.md. A scaffold request authorizes the necessary local structure; a dry-run or no-new-files request limits changes accordingly.

Core Rule

Create the requested project structure, template, and state without inventing research content. Preserve existing user files and complete compatible missing pieces instead of replacing an established project.

Workflow

1. Resolve the project location, venue, requested folders, and existing artifacts from the conversation and filesystem. Infer routine directory names; ask only about a consequential unresolved location or overwrite choice.
2. Select the matching template through ../ccf-paper-writer/references/venue-guides/index.md. Verify that the template and its supporting style/assets are available. Use supplied templates when requested; identify unavailable dependencies precisely instead of copying an incomplete template.
3. Resolve final artifacts and the working root through ../ccf-common/references/artifact-contracts.md. Create only needed directories and templates, with source/assets/cache/build subdirectories on demand. Preserve existing layout; do not migrate user files or overwrite a manuscript, bibliography, or configuration to refresh a scaffold.
4. If ccfa.yaml is absent and initialization is requested, copy assets/ccfa.yaml, preserve the required fields in ../ccf-common/references/ccfa-yaml-contract.md, and fill only supplied project metadata. Existing state is read and updated only within the requested scope; unknown research fields remain explicit placeholders.
5. Check the created paths, template references, and YAML. A build is useful when a runnable template was requested and an engine is available; do not run research experiments or final submission checks for directory setup.
6. Report the actual created/updated paths and any concrete missing dependency. For a dry run, return the proposed tree and actions without writing files.

Boundaries

Use ../ccf-common/references/artifact-contracts.md for file ownership. Project workflow planning belongs to ccf-pipeline-orchestrator, manuscript prose to ccf-paper-writer, and final package checks to ccf-submission-checker. Do not invent a title, abstract, claim, experiment, or citation.
