Coerce LLM output fields that should be strings but came as dicts/lists. The LLM sometimes returns structured objects for fields like size_in

Collect training results from output files.

Proactive context compaction: trim old tool results when context grows large. Inspired by OpenClaw's cache-aware pruning: when total content exce

Compile with pdflatex + bibtex (3-pass).

Compile with tectonic — handles bibtex cycle automatically.

Run deterministic computational analysis alongside LLM analysis.

Copy figure PDF/PNG files from figures/ to drafts/ for compilation.

Copy .sty/.cls/.bst files bundled with *template_format* to drafts/.

Count pages in a PDF file. Returns None if unavailable.

Create (or reuse) a per-session conda env and return env_info dict. Steps: 1. Check if env already exists (resume idempotency).

Introduction: topic, gaps, hypothesis, method brief, cite keys.

Full-document figure dedup (safety net after assembly).

Remove duplicate figure blocks across sections (keep first occurrence).

Derive quality signal from stage output for SDPO training.

Design the code structure based on blueprint and cloned repos.

Return (bibtex_type, venue_field) based on venue name.

Deterministic whitespace trimming — no LLM, always reliable. Two-pass approach: 1. Basic bbox crop (remove outer whitespace margins)

Use LLM to diagnose why image generation failed and produce a shorter, optimized prompt.

Send full context to LLM, get diagnosis + structured patches.

Produce a human-readable diagnosis for environment creation failure.

Try to download a missing data file. Security: validates URL scheme (http/https only) and uses shlex.quote.

Download pretrained models and datasets to global cache. Download priority for models: 1. Check if already cached (skip download)

r"""Truncate itemize blocks to *max_items* in the Introduction section. Only targets the first itemize block found between \section{Introduct

r"""Ensure every \includegraphics has a height cap. Handles two cases: 1. \includegraphics[width=...]{file} -- add height if missing

Add a conservative execution contract if the planner omitted one.

Materialize deterministic runner assets for legacy experiment projects.

Insert constrained GPT-written references for figure blocks not cited in prose.

Inject concise paper-facing related-work citations until min_refs. The injected text is literature context only. It does not introduce

Run _execute_code and also return the venv python path for reuse.

Expand paper metadata with role-targeted OpenAlex searches. This is a paper-writing safeguard: full research papers need enough liter

Use the LLM to expand prose while preserving artifact floats verbatim.

Expand only prose blocks while preserving artifact tables/figures verbatim.

Extract a balanced JSON object/array substring starting at ``start``.

r"""Extract sentences containing \cite commands. Returns list of (sentence_text, [cite_key1, cite_key2, ...]). Only returns sentences from th

Scan README, download scripts, and configs for real download URLs.

Return likely JSON substrings from raw LLM output.

Extract implementation details (epochs, GPU, lr, loss weights) from Method section. These are passed to Experiments section context so it doe

Extract a flat metric snapshot from raw execution artifacts.

Extract scalar metrics from an epoch-level training-log array.

Extract a BibTeX-safe surname from an author name string. Handles multi-word surnames (van der Waals → vanderwaals), single-name auth

Return (name, description) from YAML frontmatter, or ("", "").

Fetch the repository file tree (first 100 files).

Fetch repository README content.

Find the best metric values across all rounds.

Return an existing Python environment that already satisfies imports.

Find shell/Python scripts whose name suggests data downloading.

Check if a previous SLURM job exists (from a crashed run). Returns (job_id, status) if found, None otherwise.

Find the matching closing brace for ``text[open_brace_index] == '{'``.

Return the primary metric name from blueprint, or first available.

r"""Find a result subsection for fallback figure placement. Result figures must be placed inside the Experiments section. Without thi

Find span of ``\\begin{table}...\\end{table}`` enclosing *label*.
