A Claude Skill that strips the signatures of machine-written prose from a draft.
It is voice-neutral. It doesn't make your writing sound like anyone in particular — it removes the patterns that make text read as generated, so whatever voice the piece is meant to have can come through. Use it on articles, posts, emails, reports, documentation, marketing copy, or to diagnose why a draft feels off when nobody can name why.
- Content tells — inflated significance, analysis tacked on with a participle, notability puffery, promotional drift, vague attribution, the challenges-and-future-outlook formula, summary closes, didactic disclaimers, speculation dressed as sourcing
- Language tells — AI vocabulary and its drift by model generation, the copulative dodge (
serves asforis), negative parallelism, the rule of three, elegant variation, English-variety mismatch - Formatting tells — title case, scattered boldface, inline-header bullet lists, em-dash rhythm, emoji as structure, curly quotes, tables for two facts
- Residue tells — chat text addressed to the operator, unfilled placeholders, citation artefacts (
oaicite,turn0search,[cite: 17],【85†…】), tracking parameters on cited URLs, and fabricated sourcing - What human writing looks like — positive targets, not just prohibitions
- What is not a tell — the false positives, because over-correcting produces worse prose than the original problem
- A revision checklist to run over a finished draft
/plugin marketplace add theclockworkcloud/human-voice
/plugin install human-voice@human-voice
Or, without the plugin system, clone the repo and symlink the skill into your config:
git clone https://github.com/theclockworkcloud/human-voice.git
ln -s "$PWD/human-voice/skills/human-voice" ~/.claude/skills/human-voiceDownload human-voice.zip from Releases, then: Settings → Capabilities → Skills → Create skill → upload the zip.
To build the zip yourself: ./build.sh
An admin uploads the same zip at claude.com → Organisation settings → Skills. Everyone in the org gets it.
Note that the plugin route installs per user and does not propagate across an organisation. If you want a team to have this without each person installing it, the admin zip upload is the path.

These are observations, not rules. They describe what generated text tends to do; they are not a style guide for what good writing must avoid. Human writing is being pulled toward the same patterns by exposure, so none of this has ever proved authorship, and it proves it less each year. Weigh the stack, not the instance — and don't let the checklist talk you into worse sentences.
