Declauding

Declauding

Turn LLM-shaped prose into prose a human technical writer would have written.

Two output modes:

• clean (default) — the rewritten text, nothing else.
• annotated — a single-file HTML artifact: rewritten text, every changed passage marked, each with the original, the tic name, and why it goes. A toggle hides the marks so the result can be read straight through.

Three ways it gets called, which change what you deliver:

• Pasted text (default) — the user gives text in the conversation. Return the rewrite, plus a short list of what changed if the edit was substantial.
• File — the user points at a path. Rewrite the file in place and report a summary in the conversation rather than pasting the whole result back. Edit prose only: leave code blocks, frontmatter, data, link targets and quoted specimens alone.
• Embedded — another skill or agent is calling this as one step of a larger job (a PR description, a commit message, a doc). Return the final text and nothing else. No preamble, no summary, no tic list.

Do not invent specifics

The rewrite must not contain a fact, name, number, date, quote or citation that is not in the source. This is the failure mode the skill invites rather than prevents: the fix for a vague sentence is a specific one, and the specific has to come from the source or from the author.

Experts believe it plays a crucial role becomes the sources here do not say who studies it, or gets cut. It does not become researchers at Lanzhou University unless the source says so. When a sentence needs real-world detail to work, ask for it or write the plain version without it.

Opinions and stance count as voice rather than fact. Keeping the author's judgment is required (see Overcorrection); adding a factual claim they did not make is a defect even when the result reads more human.

The one pattern

Almost every tic in references/register.md is a version of the same move: the sentence is built to make the reader feel a finding arrive, instead of stating the finding.

The generative test, applied per sentence: am I saying the thing, or performing having had the thought? Say the thing.

Entries 24 to 36 are a second family — the flatter encyclopedic and chatbot patterns, where nothing is being staged and the writing is just running on defaults. Copula avoidance, participle tails, forced triads, chatbot residue. Different mechanism, same pass. Entries 37 and 38 are back in the staging family.

Entries 43 to 47 are a third family, and they are this skill's own output. The register a clean pass lands in — flat, concrete, verdict-shaped — is the fastest-growing cluster of GitHub pull request descriptions there is: 0.70% of early 2025, 39.5% of August 2026, with plainly, quietly, refusal, re-derived and byte-identical among its highest-lift words. references/corpus.md has the measurement. Flat certainty has tics of its own, and the test is the same one register over: am I stating the finding, or performing having settled it?

The response to that is not to put the staging back. It is to check that an adverb, a hyphenated compound or an absolute negative is carrying evidence rather than standing in for it.

Entries 48 to 52 are a fourth family and come from outside: Simon Willison's llm-cliche-highlighter, updated 2026-08-27. They are the confiding-essayist voice — announced honesty, a reversal landed on a bare auxiliary, a grade applied to a passage the reader has already read, a part claimed as a whole, an obituary headline. Staging again, but aimed at the reader's trust rather than at a finding.

The author's own writing outranks this skill

If the user supplies a sample of their writing, read it before editing and match its habits: sentence lengths, paragraph openings, punctuation, recurring phrases, vocabulary level. Do not upgrade casual words, regularize deliberate quirks, or apply a register rule the sample contradicts.

The sample wins over every rule here, including the em-dash density guard in entry 16. If the author uses em dashes at three per hundred words, that is their voice, and scrubbing the tell would make the text less like them and no more human. The same holds for their existing published work when it is available and the current draft is not.

Workflow

Script paths below are relative to this skill's directory. From any other working directory, prefix them with /mnt/skills/user/declauding/.

1. Read the whole piece before editing anything. Tics carry factual errors. A sentence written to sound important is disproportionately likely to be wrong, because it was built for shape rather than for accuracy. Designations of the form the X that answers the real question frequently designate the wrong X, and the draft itself often contradicts them a paragraph later. Note contradictions now; they are the most valuable thing this pass produces.

2. Run the mechanical scan.

python3 scripts/declaude_lint.py DRAFT.md
python3 scripts/declaude_lint.py DRAFT.html               # HTML is flattened automatically
python3 scripts/declaude_lint.py DRAFT.md --skip-quoted   # if the draft quotes bad prose

It flags greppable tells with line numbers and categories, plus four shapes that are not lexical: forced triads in both their comma-list and anaphora forms, one-line-paragraph beats, fragment runs, and constructions the document uses more than once. The reuse block is the cheapest signal it produces, because a construction used twice is a habit and counting is free.

It has no judgment. Everything it flags still needs the sentence-level test, it reaches roughly two thirds of what a careful pass finds, and the third it misses is the expensive third: staged paragraph shape, staged closers, dressed metaphor, and every earned exception in the tables below. Step 2b takes part of that third; the rest is yours. Treat a clean report as meaningless on its own.

Use --skip-quoted on any draft that quotes bad prose as a specimen. Without it the scan reports the draft's own examples, which is how a real pass loses time.

HTML input is flattened before scanning: <h1>–<h6> become headings so the header rules see them, and a .subtitle, .eyebrow or .post-meta element is treated as a heading too, because a subtitle is a header by every test that matters. Force with --html, disable with --no-html. Reported line numbers refer to the flattened view.

The corpus-register density line locates a register. It does not detect an author. Above roughly 1.0 per 100 words the draft sits in the cluster's register, and a person who chooses that register scores there too, so the line is a cue to read entries 43 to 47 and never a licence to cut nothing or measured on sight. references/corpus.md has the figures.

Lint every string that reaches the reader, not only the body file. Page titles, subtitles and deck headers are prose, and a builder that takes them as CLI arguments rather than from the file will hide them from this scan.

2a. Optionally, rank the sentences.

python3 scripts/declaude_rank.py DRAFT.md --top 15

A fitted direction in embedding space — the mean of embed(was) - embed(now) over the before/after pairs in references/register.md — that sorts sentences by how staged they look. It reaches the structural third the regex scan cannot, and it decides nothing: read each one and apply the sentence test. On the one pass it has been measured against it put all nine edited sentences at a median rank of 13 of 53, where the regex scan had found one of the nine. It cannot rank documents and does not offer a score for one. Needs torch and transformers; every other stage is standard library. references/preservation.md has the numbers and the failures.

2b. Run the structural review.

python3 scripts/declaude_review.py DRAFT.md

This is the third the scan cannot reach. It extracts the slots regex cannot judge — every header, the opening sentence, each closing sentence, isolated one-sentence paragraphs — and sends only those to a model with the structural entries from references/register.md. Slots rather than the whole document, because the payload stays small enough to run on every draft. Use --emit-prompt where no API key is available, --slots to see the extraction alone.

The two stages do not subsume each other. Stage 1 finds the flat verdict header deterministically and over-flags commas, including the ones that belong to a citation. Stage 2 reads a comma in context and finds the aphoristic closer, which no regex reaches. Run both.

Run stage 2 in a context that did not write the draft. A model reviewing its own prose is the actor that chose the words.

For a full-document register review against a named voice signature — positive markers, drift across the piece, imposter test — use the challenging skill's prose-register profile instead. This script is the cheap pass; that one is the thorough one.

3. Sentence pass. For every sentence, in order: stating or staging? Load references/register.md for the catalogue of tells and their fixes. On a draft this skill or another model already cleaned, read entries 43 to 47 first — a second pass over already-flat prose is where they live. On a personal essay, a launch post, or anything addressed to the reader as a confidant, read 48 to 52 first instead.

4. Structure pass. Headers (are they labels or verdicts?), paragraph breaks (is an isolated line a real pivot or a drum roll?), fragment runs, rhetorical questions, and the closer (does the last paragraph paraphrase the subtext of what preceded it? delete it).

5. Check what the edit did.

python3 scripts/declaude_diff.py SOURCE.md REWRITE.md
python3 scripts/declaude_diff.py --git path/to/draft.html --ref HEAD

Run this before reporting the pass done. It compares source against rewrite for numbers, names, quotations, code and link targets by presence, and for superlative, scope, negation and hedge constructions by count, and reports what the edit lost and what it invented. Constructions rather than tokens, because rewriting "the format that most invites staged reveals" as "more than most formats do" keeps the word and drops the ranking.

An embedding similarity does not substitute for it: on the three real cases in references/preservation.md the lossy rewrite scores higher cosine to the source than the faithful one. Paraphrase invariance is what an encoder is trained for, and dropping a ranking word is a paraphrase by that measure.

The script guards claims and not voice, and a finding is a question rather than a verdict — a rephrasing it cannot see through takes a --waive. Four failure modes, all of them common:

• Content lost. Ask it as a question and answer it claim by claim, not paragraph by paragraph: does the rewrite drop a claim the source made? A dropped superlative leaves the paragraph looking intact, which is why the read-through misses it. Every fact, number, caveat and hedge-with-content must survive; a tic wrapping a real qualification is still a real qualification. See Earned exceptions for what hides inside a watched phrase. Structure is free — merge or split paragraphs, compress the dull parts, dwell where the author would. When keeping the information and mirroring the original's shape pull against each other, the information wins.
• Claims changed. Rewriting "the drop is largest where chains are longest" into "long chains cause the drop" is an edit that invents a finding. Register only.
• Facts invented. Ask it directly: does the rewrite state any name, number, date or citation that is not in the source? See "Do not invent specifics" above.
• Mush. See Overcorrection below.

6. Report factual problems separately. Never silently fix a contradiction found while editing. The author needs to know their draft disagreed with itself, and only they can say which version is true.

Overcorrection

The failure mode of this skill is prose stripped of confidence, rhythm and personality until every sentence is the same length and the writer has no opinions. That is worse than the tics.

• Flat is not hedged. "Class imbalance breaks the metric before overfitting does" is flat and certain. Target plain-and-sure, never plain-and-timid.
• Do not delete first-person judgment. "I did not expect the overlap to survive a 3x range in bits per weight" is exactly right — specific, falsifiable, personal. Human technical writers state preferences and surprise directly.
• Do not enforce uniform sentence length. Short for facts, compound for dependencies and caveats. Variation carries information; monotony is its own tell.
• Do not delete metaphor. Delete metaphor that is doing significance work where a plain noun fits. A metaphor that is the clearest available description stays.
• Digression, asides and mild informality are human. Symmetry, antithesis and balanced parallel clauses are not.

Leave these alone

These are evidence of a person writing. Editing them out is how a register pass makes a draft worse, and each one is easier to destroy than to put back.

• Specific, hard-to-fabricate detail. A street name, an odd quote, "the guy who used to run the build before he left". Models round specifics off; people hoard them.
• Mixed feelings and unresolved tension. I think this is mostly right and it still bothers me and I cannot say why. Clean takes are the model default.
• Genuine self-interruption. A parenthesis that corrects the sentence it sits in, an aside that goes nowhere. Models rarely interrupt themselves.
• Repetition of a word where a synonym would be worse. That is entry 27 read in the right direction.
• Uneven depth. Three paragraphs on the part the author cares about and one line on the part they do not is how people write.
• Dated and subcultural references. Slang or in-jokes pinned to a year.

Things that are not tells on their own, and should not be edited on their own: polished grammar, formal vocabulary, a mixed casual-and-formal register, curly quotes, a single em dash, one short emphatic sentence, an unsourced claim, a salutation or sign-off. Look for clusters. One em dash is punctuation; em dashes plus a forced triad plus vibrant tapestry plus a Conclusion section is a confession.

Do not edit a watched phrase inside a quotation, a title, a proper name, or an example where the phrase is being discussed rather than used. The linter's --skip-quoted does this mechanically; do it by eye too.

Earned exceptions

Every entry fires on a shape, and a shape sometimes carries a claim. Cutting it then removes content while looking like it removed only style, and the result reads fluently, so a read-through does not catch it. Check before deleting.

Staging shapes, entries 1 to 23 and 37:

Encyclopedic shapes, entries 24 to 36:

Reference-prose shapes, entries 39 to 42:

Flat-certainty shapes, entries 43 to 47:

Confiding-essayist shapes, entries 48 to 52:

Modifiers inside a watched phrase carry content. "The single most important new build" ranks that item against every other item; "the important new build" ranks nothing. "Simultaneously X, Y and Z" claims the three hold at once; "X, Y and Z" does not. Superlatives, rankings, simultaneity, scope words, and the condition attached to a hedge all live inside phrasings this skill cuts.

Annotated mode

Read references/annotating.md. It specifies the artifact: markup for changed spans and edit notes, the toggle, the tic-tally table, and how to handle passages deliberately left alone.

Rules that make the annotation useful rather than decorative:

• Quote the original verbatim in every note. An edit the reader cannot check is an assertion.
• Name the tic using the register's vocabulary so the reader accumulates a vocabulary rather than 40 unrelated opinions.
• Say why this instance is a tic. Explaining the category teaches nothing about the text in front of the reader.
• Mark what was kept and why. A pass that only flags failures teaches avoidance.
• Bundle stacked tics into one note per passage. Do not split a sentence into four notes to inflate the count.

Calibration

When a draft's register is genuinely unclear, read real prose in the target genre before editing — the author's own earlier writing, or a well-known human writer in that domain. Human technical prose runs on, digresses, states preferences without justifying them, and repeats a word rather than reaching for elegant variation. Its sentences vary because the thoughts vary.

Scope

Applies to: blog posts, READMEs, PR and commit descriptions, reports, documentation, essays, release notes, technical explainers.

Do not apply to: fiction and poetry (different register entirely), direct quotations, other people's text being quoted, marketing copy where the client wants the staging, or anything where the "tic" is the author's established voice. Ask before running this on someone else's writing rather than a draft.

Extending

The register is a working document, not a standard. Adding to it:

1. Add the specimen to tests/sample-tics.md, verbatim from real prose.
2. Add a register entry: tell, why, fix, and the real before/after. Entries without a before/after get argued about instead of applied.
3. If the tell is lexical, add a rule to scripts/declaude_lint.py and confirm tests/sample-clean.md still reports zero. That file is human-written prose; a rule that fires on it is a bad rule, and the false-positive budget is the thing that keeps the linter worth running.
4. Bump metadata.version.

Promote a phrase to its own register entry only after it appears twice in real drafts. Reuse is the strongest evidence that a construction is a habit rather than a choice, and a register that grows on single sightings becomes a phrase blocklist that misses the next paraphrase.
