What it does

Finman Internet Appendix is an agent skill from brycewang-stanford/Awesome-Journal-Skills. Use when deciding what belongs in a Financial Management (FM) internet appendix vs. the main paper, and how to organize it so each supplementary exhibit maps to a main-text claim. Structures supporting material; it does not establish results (finman-identification / finman-robustness) or finalize the data/code package (finman-submission).

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

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.

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Index it. Open the appendix with a short table of contents mapping each IA exhibit to the main-text section or referee point it supports.
  2. Cross-reference both ways. The main text says "see Internet Appendix Table IA.3"; the IA exhibit's note says which main-text claim it backs.
  3. Keep numbering distinct. Use an IA prefix (Table IA.1, Figure IA.1) so the main and supplementary sets never collide.
  4. Make each IA exhibit self-contained. Same standard as the main exhibits — sample, units, clustering, period in the note — because referees…

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

Finman Internet Appendix loads about 1.7k tokens when it runs. Until then it costs about 91 tokens; SKILL.md has 915 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~91
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k

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.

description
Use when deciding what belongs in a Financial Management (FM) internet appendix vs. the main paper, and how to organize it so each supplementary exhibit maps to a main-text claim. Structures supporting material; it does not establish results (finman-identification / finman-robustness) or finalize the data/code package (finman-submission).

Internet Appendix (finman-internet-appendix)

When to trigger

  • The main paper is bloated with secondary tables that crowd the headline result
  • A referee asked for a check whose result is reassuring but not central to the story
  • Variable-construction detail, sample screens, or derivations are too long for the main text
  • You are about to submit and need the supplementary materials organized and labeled

The FM internet-appendix bar

FM's "people actually read" brand and its less weight on trivial robustness stance make the internet appendix a strategic tool, not a dumping ground. The main paper should carry only what a reader needs to be convinced; everything that is reassuring but not load-bearing belongs in the internet appendix. The discipline is traceability: every internet-appendix exhibit must map to a specific main-text claim or referee concern, and the main text must point to it where relevant. An appendix that is a disorganized pile of leftover tables undercuts the paper; one that is a clean, indexed companion makes the main paper lean and the author look in command of the evidence. (FM's exact archiving/hosting and data-and-code policy — 待核实 against the Wiley author guidelines at submission time.)

Organizing sequence

  1. Index it. Open the appendix with a short table of contents mapping each IA exhibit to the main-text section or referee point it supports.
  2. Cross-reference both ways. The main text says "see Internet Appendix Table IA.3"; the IA exhibit's note says which main-text claim it backs.
  3. Keep numbering distinct. Use an IA prefix (Table IA.1, Figure IA.1) so the main and supplementary sets never collide.
  4. Make each IA exhibit self-contained. Same standard as the main exhibits — sample, units, clustering, period in the note — because referees read the IA without re-reading the paper.
  5. Resist scope creep. If an IA exhibit is doing real persuasive work for a binding concern, promote it to the main paper; if it persuades no one of anything, cut it.

Checklist

  • The internet appendix opens with an index mapping each exhibit to a main-text claim or referee point
  • Every IA exhibit is cross-referenced from the main text where relevant
  • IA numbering is distinct (IA.1, IA.2 …) and never collides with the main set
  • Each IA exhibit is self-contained (sample, units, clustering, period in the note)
  • Load-bearing material was promoted to the main paper; dead weight was cut, not parked
  • Full variable definitions and sample screens live here, summarized in the main text

Anti-patterns

  • An internet appendix that is an unindexed pile of leftover tables
  • IA exhibits referenced nowhere in the main text (orphans)
  • A genuinely decisive check hidden in the appendix where the editor may miss it
  • IA numbering that overlaps the main paper and confuses cross-references
  • Treating the appendix as a place to satisfy the urge for trivial robustness FM under-weights
  • IA exhibits with no self-contained notes, forcing the referee back into the paper

Worked vignette (illustrative)

A draft's main paper has eighteen tables, several of them winsorization and control-set sweeps; the headline gets lost. The FM fix: keep five exhibits in the main paper (summary stats, the headline table, the event-study figure, the one Oster sensitivity check, and the economic-magnitude exhibit), move the thirteen sweeps and secondary subsamples to an indexed internet appendix (Tables IA.1–IA.13), and add cross-references both ways. One placebo table that actually rules out a confound gets promoted into the main paper. The main paper is now readable in one sitting and the appendix is a clean, navigable companion.

The promote / park / cut decision

For every candidate supplementary exhibit, make a deliberate call rather than defaulting to "park it":

  • Promote to the main paper if it defuses a binding concern (the editor or a likely referee would reject without it). Decisive evidence buried in an appendix is a wasted asset.
  • Park in the internet appendix if it is reassuring and a referee may want it, but no reader needs it to be convinced (alternative measures, secondary subsamples, full variable tables).
  • Cut entirely if it persuades no one of anything — FM's under-weighting of trivial robustness means a sweep that varies nothing material is dead weight even in the appendix.

This three-way call is the actual craft; an appendix that is purely "everything that didn't fit" signals the author never made it.

Referee pushback mapped to the appendix fix

  • "The paper is too long / I lost the thread." → Move secondary and sweep tables to an indexed internet appendix; keep the main paper lean.
  • "Where is the check you mention?" → Add two-way cross-references between the text and each IA exhibit.
  • "This appendix is a mess." → Open with an exhibit→claim index and give every IA exhibit a self-contained note.

Code and data alongside the appendix

The internet appendix usually travels with the replication materials. Keep them in sync from the first submission: the IA exhibits should be reproducible from the deposited code, variable definitions in the IA must match the code's construction, and any data-access restrictions (vendor licenses on Compustat, CRSP, governance feeds) should be stated so a referee or the editorial office knows what can and cannot be shared. (FM/Wiley's exact data-and-code policy — 待核实; confirm before depositing.)
