What it does

Mathfin Writing Style is an agent skill from brycewang-stanford/Awesome-Journal-Skills. Use when polishing a Mathematical Finance (Wiley) manuscript's theorem-first exposition — definitions, numbered assumptions, theorem statements, proof sketches, appendices, notation discipline for a stochastic-analysis readership, numerical-experiment prose, and the financial-modelling intuition that accompanies each formal result.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Writing & Content, covering Brand voice and tone. The repository describes itself as: Journal-specific Claude Code/Codex skill packs covering mainstream journals — AER, QJE, Nature, Cell, 管理世界, 经济研究 & 200+ more — your fast track to getting published. | 覆盖主流期刊的… The licence is MIT.

When your agent uses it

  • Numbered assumptions
  • Theorem statements
  • Notation discipline for a stochastic-analysis readership

Example prompts

  • “/mathfin-writing-style”

What it can do on your machine

Read from SKILL.md and the folder at commit 932eb23. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Mathfin Writing Style loads about 1.2k tokens when it runs. Until then it costs about 89 tokens; SKILL.md has 479 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~89
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Writing Style (mathfin-writing-style)

When to trigger

  • The proofs are correct but the paper is hard to read
  • The introduction states results without financial modelling intuition
  • Definitions, assumptions, theorem numbering, or appendix references are inconsistent

Style principles

  • Define before use. Probability space, filtration, admissible strategies, integrability, market model, and payoff objects must be explicit.
  • Number assumptions and results. Reuse labels consistently.
  • State theorem scope precisely. Hypotheses and conclusions should be visible without searching prose.
  • Separate intuition from proof. Give financial meaning before technical proof, then keep the proof self-contained.
  • Use appendices deliberately. Put long derivations there while keeping the main text focused on result, intuition, and modelling payoff.

Theorem paragraph pattern

text
Under Assumptions (A1)-(A3), Theorem 2.1 establishes [formal result]. In financial
terms, this means [pricing/hedging/risk/portfolio interpretation]. The proof
combines [main tools] and is given in [location].

Proof hygiene

  • Check local martingale versus true martingale claims.
  • State integrability and measurability conditions.
  • Do not cite a theorem without verifying its hypotheses.
  • Avoid "straightforward" for load-bearing steps.
  • Keep notation stable across the main text and appendix.

Symbol conventions the readership expects

Filtration(F_t) with the usual conditions stated onceswitching between F_t and F(t)
Physical / pricing measureP / Q (or Q^*)reusing Q for a generic measure mid-paper
Brownian motionW under P; W^Q after Girsanovthe same W under both measures without comment
Admissible strategiesA or A(x), x the initial wealth"admissible" used before A is defined

Stopping timestau, ranging over a defined family T_{t,T}tau ranging over an unspecified set
GeneratorL (or L^a in control problems)applying L to functions outside its stated domain

Proof-sketch scaffold

Before each long proof, give a three-to-five sentence sketch:

text
The proof proceeds in three steps. Step 1 establishes [a priori estimate] under (A2), which
yields the uniform integrability needed later. Step 2 constructs the candidate [object] via
[tool: Snell envelope / dual problem / fixed point]; this is where the new idea, [one phrase],
enters. Step 3 verifies optimality and uniqueness by [verification argument]. Steps 1 and 3
are standard given Step 2 and are deferred to Appendix B.

The sketch tells a referee where the novelty lives and which parts may be verified quickly — exactly the separation of new idea from routine verification that this journal's culture prizes.

Sentence-level habits for stochastic-analysis prose

  • Quantify every "small", "sufficiently regular", or "for t large" with a displayed condition.
  • Write "P-a.s." or "for Lebesgue-a.e. t" — never leave the null-set sense ambiguous.
  • Prefer "By Theorem 2.3 of [X], whose hypotheses hold by (A1) and Lemma 3.2," to a bare citation.
  • Keep proofs in one tense (present), and let displayed equations carry the algebra, not prose.

Notation ledger

Before polishing prose, create a notation ledger with columns for symbol, object, first definition, assumptions, theorem use, and appendix use. Use it to find:

  • one symbol used for multiple objects;
  • objects introduced only inside proofs but needed in theorem statements;
  • filtrations, measures, admissible sets, or payoff spaces that change silently;
  • assumptions cited in prose but absent from the theorem statement;
  • appendix notation that no longer matches the main text after revision.

Mathematical Finance readers will forgive technical density more readily than notation drift. A clean ledger also shortens referee response time because every objection can be tied to a labelled object.
