# Analyze Variation Reports rhythm (within-post sentence-length variation) and length spread (across a sequence of posts), and flags **monotone** posts and **too-similar neighbors**. > **Why this is a skill with a script, not a prompt:** length and rhythm metrics > must be deterministic. The numbers are computed by the bundled Node script — > this skill just tells the agent to run it and how to read the output. Do not > eyeball the counts; run the script. ## When to use - Before scheduling a batch of social posts, to check the feed won't read as a same-length content machine. - Reviewing journal/blog drafts or any prose for metronomic cadence. - Whenever a house style asks to "vary sentence and post length" (the measurement is voice-agnostic; the style rules stay in the project's own voice doc). ## How to run Always execute the bundled script — never compute the metrics yourself. The script lives at `scripts/analyze-variation.mjs` **inside this skill's own directory**. Resolve that directory however your harness exposes it, then run the absolute path with Node: - Claude Code: `$CLAUDE_PLUGIN_ROOT/skills/analyze-variation/scripts/analyze-variation.mjs` - opencode / other Agent Skills hosts: use the absolute path to this `SKILL.md`'s directory + `/scripts/analyze-variation.mjs` (the env var above is Claude-Code-only). ```bash # pick whichever resolves on your harness; SCRIPT points at the bundled .mjs SCRIPT="$CLAUDE_PLUGIN_ROOT/skills/analyze-variation/scripts/a...
