meta-paper-write (Meta-Skill)

Draft a long LaTeX manuscript by orchestrating paper-specific skills and bounded LLM synthesis. The pipeline now leads with explicit experiment design + placeholder figures/tables + citation provenance audit so the deliverable can be reviewed for academic rigor, not just length.

DAG (in order):

1. paper_collect — extracts topic, mode, language, target length, audience, and reference count from the same turn without pausing for a form. Missing facts are marked as assumptions so first-pass paper requests complete inline.
2. paper_preferences — expand the collected facts into a planning contract.
3. search_papers — sends a clean academic query to Crossref, Brave, and Tavily; backend-specific academic filtering stays with each engine.
4. refbib — paper-refbib-stub now extracts eprint/doi from arXiv/DOI URLs and tags each entry with note = {source: <domain>} so downstream gates can classify provenance without re-fetching.
5. source_pack — curates unique, relevant, verifiable references and emits a machine-readable usable count against the integer citation target.
6. source_readiness_gate — deterministically blocks before experiment design or drafting when the curated primary references cannot meet the target, reporting a concrete found/required count.
7. experiment_design — decides how many figures and tables the paper needs based on RQs, hypotheses, analysis dimensions, and the target page budget. Every figure/table is tied to an RQ or analysis dimension; no decorative artefacts.
8. figure_placeholders — render LaTeX \fbox{\parbox{...}} placeholder figure environments for each entry in FIGURE_PLAN. Zero matplotlib dependency.
9. table_placeholders — render LaTeX \begin{tabular} placeholder tables for each entry in TABLE_PLAN. Cells contain ---/<TBD>; no fabricated numbers.
10. analysis_outline — bind every figure/table id to a Discussion subsection that names potential findings + threats to validity, and covers every ANALYSIS_DIMENSION.
11. outline — paper outline that ties Method to experiment design and Results to the figure/table plan.
12. citation_plan — assigns concrete cite keys from refbib to claims; cannot invent keys.
13. writing_plan + section authors — the explicit FULL_MANUSCRIPT path converts the user's page target into section-level target_words and citation budgets before prose is written; section authors obey that plan.
14. final_manuscript_package — the lower-latency compact path still writes a complete, target-sized MANUSCRIPT_TEX with the figure/table/analysis blocks inlined verbatim, plus REFERENCES_BIB containing only the entries actually cited.
15. Sanitize, materialize, and preflight — persist the manuscript under the runtime-owned run directory, then compare language-aware content units with TARGET_PAGES. An undersized draft receives one bounded substantive expansion; a strict second gate must pass before compilation.
16. citation_map — strict markdown audit table: Cite Key | Cited Times | Title | URL/DOI/arXiv | Source Quality with INVALID / UNUSED / WEAK detection. Inlined into the final deliverable AND queryable per-run via opensquilla skills meta runs show.
17. Citation and publication gates — deterministically read the numeric citation_map SUMMARY; blocks when cited keys are below CITATION_TARGET, INVALID > 0, a cited source is WEAK, or the sanitized artifact violates publication rules. They never trust an LLM verdict or a fixed citation count.
18. Compile probe and bounded page repair — run the real XeLaTeX/BibTeX cycle and count pages with pypdf. A measured shortfall gets one final substantive expansion and one recompile. The runtime permits only the fixed precompile and page-shortfall repair ids and rejects citation, document-boundary, external-input, forced-page, and spacing commands.
19. Final gates / compile_pdf / publish / delivery — re-run sanitizer, length, and publication checks. An unchanged successful probe is reused by input fingerprint; a changed manuscript is recompiled once and must meet TARGET_PAGES before publish_artifact can run.

Removed from the previous version:

• paper_mode (llm_classify) — superseded by paper_collect
• experiment (skill_exec → paper-experiment-stub, fake CSV) — superseded by experiment_design (real plan, not data). The bundled paper-experiment-stub skill was deleted with this rewrite.
• plot (skill_exec → paper-plot-stub, matplotlib line chart) — superseded by figure_placeholders (zero-dependency LaTeX). The bundled paper-plot-stub skill was deleted with this rewrite.

The default path is COMPACT_SKELETON and ends with a compiled PDF without section-by-section drafting. Explicit full/PDF/long-form requests use FULL_MANUSCRIPT. If the topic is missing, paper_clarify pauses and asks the user before generation continues. The compiler refuses to synthesize a degraded PDF when the manuscript contract is missing.
