CCF Paper Writer

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. User scope and existing authorization govern execution; preserve plan-only, no-browsing, exact-output, and no-new-files requests.

This skill owns manuscript text, compression, and presentation prose. Preserve the supplied problem, method mechanism, experimental setting, numbers, citation keys, and conclusion unless a research change is authorized. A requested revision authorizes ordinary accurate wording edits and necessary local checks.

Run ccf-humanization as the first manuscript-facing preflight. Read ../ccf-humanization/references/humanization-policy.md and references/prose-quality-guardrails.md. These guide direct scientific writing; they do not start a separate review or a confirmation loop.

Writing Standard

Write from the contribution: what problem matters, why the mechanism addresses it, what the evidence establishes, and what follows. Replace reviewer-facing reassurance, apologetic novelty claims, repeated caveats, denial-led positioning, and stacked hedges with their scientific payload. Delete sentences with no payload. Do not add a limitations sentence to each paragraph, abstract, caption, or conclusion by habit.

Keep meaningful uncertainty, known negative results, necessary assumptions, fair-comparison constraints, and mandatory disclosures in direct academic prose. Do not write that a method is confirmed, approved, or publication-ready. Explain the actual method and relevant configuration. A missing result stays missing; a proposed study is not a completed experiment. Never guess citations or insert invented measurements to complete a draft.

Use the humanization policy as the single source for punctuation and pattern thresholds. Natural writing is a semantic editing task; passing a phrase checker does not establish quality. Keep scientifically necessary terms, negation, and hedging even when a heuristic flags them.

Modes And Reference Loading

An abstract, caption, synopsis, paragraph edit, or exact JSON response does not require venue guides, full exemplars, reviewer panels, or length planning by default. Load matched exemplar cards from references/exemplars/index.md only for a requested style adaptation or a full manuscript that benefits from them. Never copy exemplar wording or technical content.

Workflow

1. Identify the requested mode, output format, evidence, and target length from the conversation and supplied files. Infer routine choices; ask only for a missing decision that changes the research claim, deliverable, or feasibility. Continue independent work while that decision is pending.
2. For an authorized edit to an existing manuscript, revise that file in place and preserve Markdown/LaTeX sections, commands, citations, labels, equations, and float environments unless restructuring is requested. Follow ../ccf-common/references/artifact-contracts.md; create no dated or v2 copies for an ordinary iteration. Supplying a file for inspection alone does not authorize rewriting it.
3. For a new manuscript from research documents, use references/materials-to-manuscript.md. Draft substantive content without a page quota, check scientific and textual alignment, then fit length only when requested. Naming a venue alone does not trigger compression. An explicit submission-ready or fixed-length request includes fitting after the content check in the same task. Read references/venue-guides/index.md and the matched guide for template conventions; use references/length-budget-policy.md only in the fitting phase. Preserve a supplied template or requested format. For new LaTeX without a usable target template, NeurIPS is a disclosed format fallback, not a scientific or length requirement. references/output-style-policy.md governs format choices.
4. Organize the scientific argument. For a substantial introduction or full manuscript, use references/storyline-blueprint.md; for bounded prose, directly connect problem, insight, mechanism, evidence, and implication. Keep material scope where it changes interpretation. Do not generate a reviewer-risk register or multi-expert tournament for ordinary writing.
5. Resolve evidence prerequisites before asserting dependent claims. When literature is needed, load references/citation-workflow.md, use ccf-literature-searcher for missing sources, and update the bibliography without changing unrelated keys. Use ccf-integrity-auditor for unresolved citation-support or numerical conflicts. Reuse applicable verified evidence. For supplied-evidence-only or no-browsing tasks, preserve provided citations and keep unsupported claims provisional without inventing entries.
6. Draft substantive sections and supporting appendices using references/section-modules.md and applicable references/writing-checklists.md checks. Load references/research-writing-patterns.md only when alternative writing patterns or exemplar adaptation are useful. references/materials-to-manuscript.md owns result-status handling: preserve supplied results, leave missing values and dependent analysis blank, and honor an explicitly deferred experiment section. Do not invent mechanisms or pad with cautionary text.
7. For reported experimental comparisons, consult ../ccf-humanization/references/experiment-discipline.md when method identity or protocol matters. Use supplied design specifications for a proposed method and cited evidence for prior work; do not demand runnable checkpoints or full experimental confirmation to perform a text edit.
8. For a full LaTeX manuscript with an available engine, compile and inspect errors, references, and affected layouts. Fix overflow and missing references in every phase; page count is informational during content-first drafting. Fit length only in submission-fit or explicitly requested compression. Put build artifacts under the established working directory and export the requested PDF only after a successful build. Preserve relative includes and build configuration. Recompile after relevant changes; do not loop to fill pages or chase harmless warnings. Leave final venue compliance to ccf-submission-checker when requested or necessary.
9. Check the resulting argument once with the cohesion repairs in references/prose-quality-guardrails.md, then apply Humanization's sentence decisions and verify that factual meaning survived revision. For a full section or paper, run scripts/check_prose_quality.py when available. Inspect candidates in context; fix real problems and retain justified scientific language. Use --strict only when a strict lint report is requested, not as a universal publication gate. Rerun only for changed content or unresolved findings.
10. For a substantial draft or changes to argument/evidence, use ccf-paper-reviewer to check the affected links and coherence unless already covered. Carry the drafting phase and intentionally missing evidence into the check. A results-pending draft needs a writing/alignment check, not an invented acceptance score or an automatic new-experiment campaign. Unsupported empirical assertions still require correction. Integrate authorized fixes and verify affected passages; a local edit uses local checks. Deliver the requested artifact and concrete unresolved decisions without unrelated downstream outputs.

Output Contract

Return the actual revised text, manuscript, compressed passage, or presentation prose first in the user's format. Ordinary local edits need no mode/status/next-skill block. For full manuscript files, report their paths, substantive changes, relevant validation, and concrete unresolved evidence. Exact schemas stay exact.

A complete draft contains the requested scientific sections at appropriate depth; it may remain evidence-incomplete. Distinguish draft completion from submission readiness. Do not label unknown results as observations or claim measured score improvements from a prose revision.

References

Load selectively by the modes above. Maintain phase/result rules in materials-to-manuscript.md, section responsibilities in section-modules.md, citation rules in citation-workflow.md, and fitting rules in length-budget-policy.md; other references apply them without duplicating the full policy.

• references/materials-to-manuscript.md: research-document intake, complete initial drafts, results-pending writing, and alignment before compression.
• references/output-style-policy.md, references/length-budget-policy.md: source-format preservation and later manuscript fitting.
• references/venue-guides/index.md, references/exemplars/index.md: target venue and selected style moves.
• references/storyline-blueprint.md, references/section-modules.md, references/research-writing-patterns.md: scientific organization and section writing.
• references/citation-workflow.md: verified citation insertion.
• references/prose-quality-guardrails.md, references/writing-checklists.md, scripts/check_prose_quality.py: semantic prose review and supporting diagnostics.
• references/compression-rules.md: evidence-preserving compression.
• references/table-style-guide.md: existing LaTeX table source guidance; visual redesign belongs to ccf-visual-composer.
• references/score-lifting-loop.md, references/expert-review-loop.md: applying actual reviewer deductions when that work is requested.
• ../ccf-common/references/review-output-standards.md: conditional scores and frozen review standards, only for requested review-related outputs.
