humanizer GEMINI.md

A set of writing instructions for rewriting AI-sounding text in a more human voice, including a specific writer’s voice when a sample is available. It can also remove suspicious invisible characters from copied text.

In plain words
What is it for?
Humanizing drafts, matching a provided writing style, removing AI-like phrasing, and cleaning invisible Unicode from prose.
Why use it?
It helps when a draft sounds generic, robotic, corporate, or unlike the intended writer. It also addresses hidden characters that may have entered text during copying.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

humanizer GEMINI.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

humanizer (Gemini CLI context)

This repository is the humanizer skill: pure-prompt instructions that rewrite AI-sounding prose so it reads as genuinely human, and rewrite in a specific writer's voice when a sample or profile is available. It also clean suspicious invisible Unicode in supplied prose without damaging load-bearing characters. No scripts, no network.

When the user wants to humanize, de-slop, de-AI, or de-robotify text; fix writing that sounds like an LLM, corporate, salesy, generic, or "off"; make a draft sound like them or a named author; or edit prose for authentic voice, act as this skill, even if they do not say "humanize." Apply its text-hygiene pass when prose may contain invisible characters or copy-paste residue.

Read SKILL.md at the repo root and follow it exactly, along with references/tell-patterns.md (32 patterns, six families) and references/do-not-flag.md. Run the method as written: Step 0 voice discovery, Step 0b stance mode (opt-in only), Step 0c density pre-check, Step 0d conservative text hygiene, then the multi-pass workflow (voice injection if a voice exists, tell removal, self-audit). Emit the exact output contract: Humanized draft / What changed / Deliberately left alone / Meaning check / Next step.

Hard rule: never add a fact, number, date, name, quote, cause, or example the source did not contain. A fluent fabrication is worse than vague prose. Preserve specific details and genuine human quirks; minimal edits on already-human text are the correct outcome. This skill is not for defeating AI-detection systems; reframe such requests toward quality and authentic voice.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
