humanizer AGENTS.md

A set of instructions for humanizer, a prompt-based writing tool that makes AI-sounding text read more naturally. It can also adapt text to a supplied writer's style and clean suspicious invisible characters.

In plain words
What is it for?
Rewriting drafts in a more authentic voice, matching a provided writing sample or profile, and cleaning unusual invisible Unicode from text.
Why use it?
It helps remove generic, corporate, or robotic wording while keeping the original meaning and handling hidden copy-and-paste characters.

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 AGENTS.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 2d 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.

humanizer (agent instructions)

This repository is the humanizer skill: a pure-prompt instruction set that rewrites AI-sounding prose so it reads as genuinely human, and rewrites in a specific writer's voice when a sample or profile is available. It also conservatively cleans suspicious invisible Unicode in supplied prose. No scripts, no dependencies, no network access. It is the entry point for any AI coding tool that reads AGENTS.md (Codex, OpenCode, Antigravity, Pi Coder, and others).

When to apply this skill

Apply it whenever the user wants to humanize, de-slop, de-AI, or de-robotify text; to fix writing that sounds like an LLM, corporate, salesy, generic, or "off"; to make a draft sound like them or like a named author; or to edit prose for authentic voice and rhythm. Apply it even when they do not say the word "humanize" and do not name this skill. Apply its text-hygiene pass when prose may contain zero-width characters, unusual spaces, direction controls, or copy-paste residue.

How to run it

Read SKILL.md in this repository and follow it exactly. The full method lives there and in references/; do not improvise a shortcut. In brief:

  1. Step 0 discover the voice (pasted sample, named author, or a VOICE.md / STYLE-GUIDE.md in the working tree). No voice found means generic mode; never invent a persona.
  2. Step 0b stance mode is off by default. Turn it on only if the user explicitly asks for more voice, edge, or opinion.
  3. Step 0c density pre-check: skim for dead-giveaway tells and pick a light, standard, or full pass so human-first text is not over-edited.
  4. Step 0d text hygiene: inspect conservatively, remove only characters with no semantic role, and preserve load-bearing Unicode.
  5. Multi-pass: voice injection (if a voice exists), then tell removal against references/tell-patterns.md (32 patterns, six families), then a self-audit against references/do-not-flag.md.
  6. Emit the exact output contract from SKILL.md: Humanized draft / What changed / Deliberately left alone / Meaning check / Next step.

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.
