jacs-methods
Use when checking synthesis and characterization rigor for a Journal of the American Chemical Society (JACS) manuscript — purity, NMR/HRMS/IR/UV-vis, elemental analysis or HPLC, single-crystal X-ray/CCDC, and catalysis controls/mechanism/kinetics. Audits experimental rigor — it does not write narrative or polish prose.

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Synthesis and Characterization Rigor (jacs-methods) ## When to trigger - New compounds are reported and you must confirm full characterization - A reviewer could ask "is this compound pure?" or "where is the X-ray?" - A mechanism is claimed but only proposed, not tested - Catalysis scope/selectivity is reported and controls are unclear ## Characterization rigor by claim type JACS requires that **claims are fully supported by characterization data and appropriate controls**. Match the data package to what you assert. ### Every new, isolable compound - [ ] **¹H NMR** — solvent, field; δ (ppm), multiplicity, J (Hz), integration - [ ] **¹³C{¹H} NMR** — all resolvable carbons (note coincident peaks) - [ ] Heteronuclear NMR as relevant: **¹⁹F**, **³¹P**, **¹¹B**, etc.; 2D for assignment - [ ] **HRMS** — ionization mode, calcd vs found m/z for the assigned formula - [ ] **IR** — diagnostic bands (C=O, N–H, C≡N, M–CO, etc.) when structurally informative - [ ] **Purity evidence** — at least one of: CHN(S) elemental analysis (calcd vs found, typically within accepted tolerance), or HPLC/GC purity, plus clean NMR - [ ] Melting point / optical rotation / UV-vis as appropriate to compound cla

What does the jacs-methods skill do?
Use when checking synthesis and characterization rigor for a Journal of the American Chemical Society (JACS) manuscript — purity, NMR/HRMS/IR/UV-vis, elemental analysis or HPLC, single-crystal X-ray/CCDC, and catalysis controls/mechanism/kinetics. Audits experimental rigor — it does not write narrative or polish prose.
How do I install it?
Run `npx skills add brycewang-stanford/Awesome-Journal-Skills --skill jacs-methods --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From brycewang-stanford/Awesome-Journal-Skills, a repository with 984 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
