  • Checking synthesis and characterization rigor for a Journal of the American Chemical Society (JACS) manuscript — purity
  • SKILL.md covers When to trigger, Characterization rigor by…, Reproducibility test and Anti-patterns, plus 2 more sections

What it does

Jacs Methods is an agent skill from franklee16/academic-research-skills. 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.

Its SKILL.md is about 1.1k 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: Comprehensive collection of Claude Code skills for academic research in economics, finance, and social sciences.

When your agent uses it

  • Checking synthesis and characterization rigor for a Journal of the American Chemical Society (JACS) manuscript — purity
  • NMR/HRMS/IR/UV-vis
  • Elemental analysis
  • Single-crystal X-ray/CCDC

Example prompts

  • “/jacs-methods”

What it can do on your machine

Read from SKILL.md and the folder at commit 9a4b2db. 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

Jacs Methods loads about 1.1k tokens when it runs. Until then it costs about 83 tokens; SKILL.md has 451 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~83
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 451 words (~1,150 tokens).

“JACS requires that claims are fully supported by characterization data and appropriate controls. Match the data package to what you assert.”
