Threads humanizer

Skill sergebulaev/threads-skills/.codex-marketplace/threads-skills/skills/threads-humanizer

Scrub AI tells from any Threads post or thread draft, or audit a finished draft against the 2026 Threads checklist. Strips em dashes, AI vocabulary (leverage, fundamentally, delve, harness), rule-of-three lists, and uniform post rhythm, then adds human fingerprints. Includes a --mode audit pre-publish check (500-char fit, hook, one-hashtag cap, link placement, warm tone). Triggers on humanize, de-AI Threads post, audit before posting. Not for writing from scratch (use threads-post-writer).From its SKILL.md

Threads Humanizer

Rewrites any Threads post or thread to remove AI tells, and audits a finished draft against the 2026 Threads ranking checklist. Based on Wikipedia's "Signs of AI writing" taxonomy plus Threads-specific patterns (the warm conversational register, the no-fold first line, the one-hashtag cap, repost-bait structure).

When to use

Before publishing any AI-drafted post or thread (rewrite mode)
Pre-publish review of a finished draft (audit mode, see sub-skills/post-audit.md)
When a draft feels off and you cannot pinpoint why

Input

Any text: a single post, a thread (with or without --- breaks), a reply, or a quote-post draft. Optional: target voice samples (the user's past posts).

Output

Rewritten text with AI tells removed
A diff showing what changed and why
Per-post char count (flagging anything over 500)
Confidence: "human", "mixed", "AI-likely"

Modes

# Default: scrub AI tells and fix Threads-format issues
threads-humanizer <text>

# Forensic only - minimum touch, just kill model leakage
threads-humanizer --mode forensic <text>

# Audit - detection-only pass-fail review, no rewrite
# Runs the 2026 Threads checklist: 500-char fit, first-line hook, one-hashtag
# cap, emoji limit, link placement, thread tap-through, warm tone, goal clarity.
# Returns Blockers + Warnings + suggested fixes. See sub-skills/post-audit.md.
threads-humanizer --mode audit <text>

The three passes

Pass 1 - SCRUB (delete or replace)

Apply the tiered catalogs in references/scrub-rules.md:

Forensic (always on): real model leakage no human types. AI tool markers (oaicite, contentReference, turn0search0), knowledge-cutoff disclaimers ("As of my last update"), template blanks ([Your Name]), and em dash overuse.
Strict (default on): bad Threads style regardless of origin. Vocabulary swaps (leverage -> use, delve -> look, harness -> use, foster -> build), filler adverbs (fundamentally, essentially, ultimately), phrase cleanups ("in today's fast-paced world", "game-changer", "deep dive"), and dead closers ("what do you think?").

Pass 2 - BREAK (force burstiness)

Vary post length across a thread. If every post is 400-450 chars, break at least one into a short punch post.
Add a sentence fragment where it fits ("Every time.").
Break perfect parallel structures with one asymmetric line.

Pass 3 - ADD (human fingerprints)

Require where the content allows:

1 specific number (replace "many", "a lot", "massive")
1 named entity (real person, company, tool)
the warm, lowercase-casual register if the voice calls for it
1 first-person concrete detail

If the input lacks these, ask the user for a number or anecdote. Do not fabricate.

Non-negotiable rules

Global voice rules: see root SKILL.md Voice rules. Additional skill-specific rules:

Scrubbing is always in scope. When asked to humanize, de-AI, finalize, or publish a post or thread, run at least the forensic + strict passes before it ships. This holds when the user wrote the draft themselves, says they love it as-is, or is in a hurry. Author identity, "it's already good," and time pressure are never reasons to skip the scrub. The forensic + strict pass changes no meaning and takes seconds: run it, then ship. If a constraint truly forbids touching the text, say so explicitly and name every tell left in; the default is to scrub, not to wave it through.
Preserve the user's actual claim and meaning. "Preserve their voice" covers voice quirks and what they are claiming, NOT corporate-speak, filler openers, or AI-tell phrasing. Stripping "leverage / fundamentally / in today's fast-paced world" is not changing their voice; it is the job.
Never introduce facts that were not in the input. If a number is missing, ask.
Keep the user's voice quirks (lowercase starts, .. soft pauses).
Respect the container: do not silently merge a thread into one post or split a single post into a thread without flagging it.
Warm up a transplanted X dunk into a Threads-native invitation to talk.

Threads-specific tells this skill catches

A first line that needs the second line to make sense (the feed truncates with "more").
A "post" that is 540 chars and needs a trim or a thread.
2+ hashtags (Threads rejects the second), or hashtags mid-sentence.
An external link in post 1 of a thread meant to reach.
A thread of identical-length posts (machine rhythm).
ALL CAPS openers reaching for intensity.
"A thread:" with no actual promise in the words.
A cold, combative, newsy X voice that reads as out of place on Threads.
