Writing the synthesis — notes are the input
What it is
Produces a fixed-shape note per source: the claim, the method, the evidence, the limitation, and one quote. Fixed shape is the point — twenty notes in the same structure can be compared, twenty summaries cannot.
Install
Clone the repository, then copy the skill folder into your agent's skills directory — ~/.claude/skills/ for Claude Code. Skills are plain files: no build step, no daemon.
Terminal
npx skills add literature-noteHow to judge it
Read the SKILL.md before you install. A good skill states when it applies, what it must not do, and how to verify the result. A skill that only lists adjectives will change the agent's tone without improving its output — skip those.
