Detect and fix AI writing patterns recursively. Use when: reviewing text for AI tells, cleaning AI-generated drafts, checking for CoT leakage, measuring text perplexity and burstiness, making text sound human, fixing opening diversity. Triggers: filter-tells, ai detection, ai writing, perplexity, burstiness, CoT leakage, humanize text, opening diversity, sentence starts.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# filter-tells: AI Writing Detection and Correction
Detects mechanically, removes editorially, and hands voice restoration to
`match-voice`. Three detection layers — lexical, structural, semantic — flag
passages; Claude then rewrites them under the convergence rules below, and
re-scans. There is no deterministic strip: a banned word is a one-word swap,
but a cadence tell needs the sentence rewritten, and that is judgment.
Filtering leaves prose that is *neutral* — no tells, but no voice either. When
the passage has to sound like the author, that is `match-voice`'s job.
*Renamed from `de-ai` (2026-07). The old name implied the skill only removed;
it detects, and the removal is editorial.*
## Standing Warning: Scripts Are Blind to Rhetorical Patterns
The two scripts (`detect-lexical.sh`, `detect-structural.py`) measure surface metrics only — banned words, opening diversity, sentence length variance, dash density. They **cannot** detect the rhetorical patterns that constitute most of the AI signal in real prose:
- Declarative pairs ("X is Y. Z is W.")
- Definition-by-enumeration ("X extends in two ways")
- Meta-narrative bridges ("The analogy breaks in one place")

How to install
mdr add petar-djukic/writing-skills/filter-tells@sha256:bda13864b37e01c9The line at the top of this page pins the label git:20260901.b53aa12, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
