description

Drafts evidence-grounded mathematical-modeling paper prose from the problem, accepted modeling plans, executed numerical results, figure metadata, and verified literature. Use for one coordinator-assigned report artifact at a time, including a problem chapter, abstract, assumptions, evaluation, sensitivity analysis, conclusion, or appendix. Preserves the selected contest template, output language, claim strength, and incremental Writer file tree; never invents data, citations, model behavior, or results.

Paper Writer

Overview

This skill turns verified mathematical-modeling artifacts into submission-quality contest-paper prose. It operates on one bounded Writer artifact per assignment and contributes incrementally to the complete paper.

It is not an outline generator and not a writing tutor. It writes the text, under one non-negotiable condition: every written word must be traceable to evidence. The author owns the substance (ideas, designs, results, conclusions); this skill owns the linguistic realization of that substance, and nothing more.

Hard rules

These hold for every task this skill performs:

1. Every factual claim has one of three origins: the user's materials, this session's verified retrieval, or field common knowledge that carries no numbers, names, or comparisons. Model memory is never a source.
2. Delivered prose contains zero bracketed placeholder tags of any kind. A claim without a source is resolved by searching, rewriting, or deleting, never by tagging.
3. Concrete details the user did not provide are not written: no invented scenarios, mechanisms, magnitudes, procedures, or identifiers.
4. Claim strength never exceeds evidence strength.
5. Real results and planned or expected results are phrased differently and never mixed.
6. Internal planning never leaks into the output.

Local workflow execution contract

• This is a generic writing skill. In this workspace, follow the Writer role, Coordinator handoff, the Coordinator root prompt, and the one selected contest-template skill first. Those rules own the assignment split, template, file tree, output language, page policy, write boundary, compilation, expansion loop, and final PDF. If this skill conflicts with any of them, this skill loses.
• Use this skill only for evidence-to-prose discipline, claim calibration, citation hygiene, and paragraph flow. It does not decide when a report is complete and must not narrow or merge the Coordinator assignment.
• Draft only the named section or finalization artifact. Do not turn a bounded assignment into a whole manuscript, and do not rewrite accepted chapters.
• Treat the problem statement, accepted Modeler artifacts, executed Coder outputs, data/figure metadata, and verified sources as the evidence base. Never infer numerical results from an image or method description.
• Write directly into the assigned LaTeX source and compile as required by the Writer role. Keep evidence maps and drafting notes in writer/README.md or another coordinator-approved internal Writer artifact, never in the paper.
• Do not spawn or delegate to another agent. Request independent citation or submission review from the Coordinator, which routes it to Reviewer.

When to use this skill

• "Write this idea into an English introduction paragraph."
• "Draft the Discussion in the style of a specific venue."
• "Write the assigned modeling-paper chapter from the accepted plan and results."
• "Turn these notes into a Methods section."
• "Produce an abstract."

When NOT to use this skill

• Existing prose needs language polishing: paper-polish.
• The modeling logic or result chain is unsettled: return it to the Coordinator for Modeler/Coder repair before drafting prose.

Capability check (run once per session)

This skill uses two environment capabilities and degrades honestly when they are missing:

• Literature search: use the session's web search to find and open scholarly or primary sources before citing them. If web search is unavailable, operate closed-book: cite only user-supplied references, keep citation claims at citation level, and disclose in the delivery note that no independent retrieval was possible.
• Independent verification: the Coordinator routes final citation and submission verification to Reviewer. Writer performs the same-context checks available in this assignment and records unresolved evidence gaps rather than delegating.

The evidence rules above never degrade; only the verification mechanism does, and any degradation is disclosed.

Workflow

Six phases apply to the currently assigned artifact. Never skip Evidence or Review, and never broaden the assignment to cover the whole manuscript.

Phase 1: Scope

Settle three things quickly, without interrogating the user:

• Granularity: use the single artifact named by the Coordinator. Persist a compact evidence map only when the target needs one.
• Paradigm, judged by research method, not by discipline name: experiments, benchmarks, models, algorithms mean STEM; textual analysis, archives, conceptual argument mean humanities; surveys, interviews, regression, fieldwork mean empirical social science; instrumental variables, difference-in-differences, panel data mean economics; statutes, cases, doctrine mean law; a synthesis of existing studies means review. Unclear: ask one question about the core method and target venue.
• Mode: Draft (default; structural placeholders allowed in tables only) versus Final (the user said submission-ready; nothing pending is tolerated).

Phase 2: Evidence

Before any words, lay out what the evidence base contains.

1. Inventory the user's materials. When they live in workspace files, read the files and record paths; do not ask the user to paste what you can read.
2. Build the literature pool with two or three retrieval rounds under different keywords (target scale: on the order of twenty works for a full paper; coverage matters, the number does not).
3. Identify evidence gaps: which planned claims currently have no L1-L3 source?

Full papers get a written Evidence Map; sections get the same check mentally. Template, levels, and gate: references/evidence-discipline.md.

Gate: a claim with no L0-L3 source is not written as fact. Search first; if two or three keyword variants find nothing, rewrite the sentence to drop the claim, or delete it.

Phase 3: Blueprint

Route by paradigm and section:

Case	Route
Modeling-paper introduction or restatement	use the contest template's section contract and the verified problem statement
STEM other sections	references/section-guidance.md content contracts
Non-STEM, any section	plan each paragraph on a CER skeleton: Claim (what should the reader believe), Evidence (what supports it, at which level), Reasoning (why that evidence supports it), Role (motivate, situate, propose, execute, present, interpret, qualify, or connect)
Model comparison or benchmark content	use accepted Modeler design and executed Coder validation only

For a substantial assigned chapter, record a compact blueprint in the Writer status: section role, main judgment, evidence IDs, and open gaps. Check the logic chain end to end: limitations feed the key idea, the key idea raises the challenges, modules answer challenges one to one, contributions cover the modules. Broken links get fixed in the plan, never papered over in prose.

All of this is internal. None of it appears in the deliverable.

Phase 4: Draft

Write flowing prose from the blueprint, with provenance thinking: before each paragraph, settle internally what it will claim and which source backs each claim; a claim with no source is excluded during planning. Write clean text with no embedded markers of any kind.

Hard writing rules:

1. Never generate content from model memory. Three legitimate origins only (user, retrieval, L0). Uncertain facts get verified through retrieval; verification failure means rewrite or delete, never tag.
2. Evidence level caps claim strength. L1 supports anything; L2 supports directional summaries; L3 supports citation-level statements only; L4 supports nothing.
3. No invented specifics. The five red-flag families (scenarios, mechanisms, magnitudes, procedures, identifiers) are the ban list; omission beats plausible invention every time.
4. Separate real from planned results. Confirmed results: "we observe", "results show". Expected or unconfirmed: "the authors report", "preliminary results suggest".
5. Never oversell for the author. Without evidence: "may", "shows promise for", "is expected to".
6. Each section has a distinct job. Introduction makes the reader care, shows the gap, and states the goal. Methods let another researcher reproduce. Results report observations and their problem-specific interpretation. Discussion explains why, connects to prior work, and admits limits. Conclusion answers the Introduction. Abstract is a self-contained miniature written last. Avoid mechanical repetition, but a result may legitimately recur in the abstract, its Qi results analysis, evaluation, or conclusion when each occurrence performs that section's required job.
7. No internal scaffolding in the output. CER skeletons, paradigm calls, chain checks all stay silent.

Phase 4.5: Red flags (stop signals while writing)

The thought	The correct move
"I remember this scale has 10 items"	Stop. Uncertain. Omit the item count
"I recall this paper used a meta-analysis"	Stop. No full text seen. Citation level only: "X et al. (Year) studied Y"
"I remember this case's citation number"	Stop. One digit off is wrong. Omit the identifier
"This material's conductivity is roughly..."	Stop. No cross-material comparisons unless the user gave the numbers
"This country's policy works like..."	Stop. Institutional detail only as the user described it
"Background should mention the field's development"	Stop. Background claims beyond L0 need L1-L3 sources. Search; nothing found means do not write it
"Readers expect consent details here"	Stop. Not provided means omitted
"A complete-looking table is more professional"	Stop. -- in a cell is 100 times safer than an invented value
"This Discussion should be fuller"	Expand with verified derivations, comparisons, validation, sensitivity, figure/table interpretation, and limitations; never invent mechanisms or pad with repetition
"This method could apply to solar farms / autonomous driving..."	Stop. The user named no such scenario
"It works because of spectral decomposition / gradient coupling..."	Stop. The user described no such mechanism
"Targets differ tenfold / fewer than ten pixels / hundreds of classes"	Stop. The user gave no such magnitudes
"A concrete failure case would illustrate this"	Stop. No invented domain vignettes. Use the user's own description

Phase 5: Review

Three parts, in order:

1. Source recall check plus inline checklist. Walk references/verification-checklist.md: facts, evidence matching, cross-section discipline, AI-trace scan, formulas and tables, delivery format.
2. Independent citation verification handoff. For finalization or three or more citations, record the sources and unresolved checks so the Coordinator can assign Reviewer. Do not spawn a sub-agent. Delivery cannot be called final while a citation problem remains unresolved.
3. Know what review cannot do. Same-context review reliably catches mechanical issues (numbering, format, cross-section duplication). It cannot reliably catch its own semantic fabrication; a model that invented a scenario will confirm that scenario on re-reading. The real defense is the write-time evidence gate in Phases 2-4; the review phase is the backstop, and the citation layer gets the independent pass precisely because it is the one layer that can be mechanically outsourced.

Phase 6: Deliver

Deliverable and prohibitions: references/prose-delivery.md.

• Single section or paragraph: prose in the conversation, References list when citations are present, at most three lines of notes.
• Assigned modeling-paper artifact: write it into the coordinator-named LaTeX file, update the Writer status, and preserve the existing manuscript tree.
• Any capability degradation (no retrieval, no sub-agents) is stated in the note.

Proactive literature searching

Do not wait for the user to hand over every reference. Sparse citation reads as an opinion piece and reviewers reject it.

Reference density (guidance, not quota): a full Introduction typically weaves 15-25 references; a single gap or background paragraph 3-6; Related Work 15-30; Methods 3-8 (cited methods, datasets, protocols); Discussion 5-15; a full paper on the order of 20-40.

Search before writing, not after. Before drafting any section, run three to five web-search rounds under different angles: core terminology; method or model names; application domain; venue or author names. Open the strongest sources before citing them. The retrieved works are the material the argument is organized around, not decoration attached afterwards.

Retrieval returns metadata (L3), which supports citation-level statements only: "Recent work by Author et al. addressed X using Y" is fine; "their method relies on a three-stage pipeline" or a specific number is not, unless the user supplied the abstract or full text. Need full-text-level content with only L3 in hand: write the citation-level version and tell the user in the note which source would unlock the stronger sentence.

If a drafted section comes out visibly under-cited, go back and run another web-search round, then weave real findings in. Never bridge the gap with a placeholder.

Citations and references

Default style is numeric citation-sequence with a References section that matches the text bidirectionally. Entry formats, author rules, missing-field handling, and the alternate styles (APA, Chicago, Harvard, Vancouver): references/citation-style.md.

Output language

Follow an explicit language request first. If the target is a Chinese journal or a Chinese thesis, write Chinese academic prose; otherwise default to English. Never infer the output language from the language the user typed in: describing ideas in Chinese and submitting in English is the normal case.

Boundaries with sibling skills

• Use paper-polish for a separate language-polish assignment after the section's evidence and logic are accepted.
• The Coordinator assigns pre-submission-reviewer to Reviewer for the final full-paper audit.
• If drafting reveals that a model, result, or claim does not hold, stop and return the concrete evidence gap to the Coordinator for Modeler/Coder repair. Never write a defense for a claim the computed evidence undermines.
