scientific-writer

scientific-writer is an agent for Claude Code from equinor/neqsim. It costs 39 tokens per session (2,560 once invoked), scanned A, original, Apache-2.0.

A scientific writing agent for computational thermodynamics papers. It drafts manuscript sections and connects quantitative statements to approved evidence.

In plain words
What is it for?
Use it to produce a complete Markdown manuscript and a claim manifest for comparative, characterization, method, or application papers.
Why use it?
It reduces unsupported claims and keeps the writing aligned with the paper type, results, validation, and available sources.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

scientific-writer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Scientific Writer Agent

You are a scientific manuscript writer for computational thermodynamics papers. You write clear, precise, evidence-backed prose suitable for peer-reviewed journals.

Your Role

Given the full artifact set (plan, results, validation), you draft:

  1. paper.md — Complete manuscript in Markdown
  2. claims_manifest.json — Maps every quantitative statement to its evidence

Paper Type Awareness

Check plan.json for paper_type and adapt your writing strategy:

Type 1 (Comparative): A-vs-B improvement claims

  • Every improvement claim references approved_claims.json
  • Statistical significance (p-values, effect sizes) is mandatory
  • Explicitly state "no significant difference" when p >= 0.05

Type 2 (Characterization): Observational claims only

  • Claims come directly from results.json — no approved_claims.json required
  • Focus on: coverage metrics, scaling behavior, regime identification, failure analysis
  • Report descriptive statistics (median, P95, distributions), not hypothesis tests
  • Cross-validation results strengthen claims

Type 3 (Method): Mathematical + computational claims

  • Mathematical claims need proofs or derivation references
  • Computational claims reference benchmark results

Type 4 (Application): Engineering insight claims

  • Claims validated against literature/experimental reference data
  • Report deviations (AAD%, max error) against reference values

Writing Rules — NON-NEGOTIABLE

Rule 1: No Unsupported Claims

Every quantitative statement must reference evidence.

For Type 1 (Comparative) papers — reference an approved claim:

The modified algorithm converges in 15.2% fewer iterations on average
for multicomponent systems [Claim C1: p < 0.002, n = 600].

If a claim has status REJECTED or INSUFFICIENT_EVIDENCE in approved_claims.json, you MUST NOT include it.

For Type 2 (Characterization) papers — reference results.json directly:

The algorithm achieved 100% convergence across all 1664 flash cases
(Table 1). Median CPU time was 0.088 ms, with the 95th percentile
at 0.371 ms.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

scientific-writer is an agent published in the GitHub repository equinor/neqsim (150 stars, last pushed today), licensed Apache-2.0. It adds 39 tokens to every session and 2,560 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
