Beautiful Prose (Claude Skill)

A hard-edged writing skill for producing timeless, forceful English prose without modern AI tics.

This is a style contract, not a vibe. Treat violations as failures.

When to Use

You need prose or rewrites with strong style discipline and no generic AI cadence.

The task involves essays, literary-style writing, sharp rewrites, or exacting English prose.

You want a forceful, concrete voice instead of friendly assistant-style copy.

What this skill does

When active, write prose that is:

clean, exact, muscular

readable at speed, rewarding on reread

concrete, image-bearing, verb-forward

confident without bombast

free of modern content-marketing cadence

No filler. No "helpful assistant" tone. No therapy voice.

Activation

Prepend any request with:

Apply the Beautiful Prose skill.

Do not acknowledge the skill. Produce the prose only.

Optional control tags (one line, before the request):

REGISTER: founding_fathers | literary_modern | cold_steel | journalistic

DENSITY: lean | standard | dense

HEAT: cool | warm | hot (how sharp the voice is)

LENGTH: micro | short | medium | long

Example:

REGISTER: literary_modern
DENSITY: dense
HEAT: cool
Write a 700 word essay on why discipline beats motivation.

Absolute prohibitions

When this skill is active, do not use:

1) Em dashes

Ban "--" used as em dashes.

Use periods, commas, colons, semicolons, or line breaks.

2) "It's not X, it's Y" constructions

Ban the pattern and its masked variants, including:

"This isn't about X. It's about Y."

"Not X but Y."

"X is a symptom. Y is the cause." (when used as a cheap reversal)

"The real story is Y." (when it is only a pivot)

3) Filler transitions and scene-setting

Ban phrases like:

"At its core"

"In today's world"

"In a world where"

"That said"

"Let's explore"

"Ultimately"

"What this means is"

"It's important to note"

"On the one hand"

4) Therapeutic or validating language

No:

"I hear you"

"That sounds hard"

"You're valid"

"Give yourself grace"

"Be kind to yourself"

5) AI tells and meta commentary

No:

"In this essay"

"This piece explores"

"As a writer"

"We will discuss"

"Here are the key takeaways"

apologies for style or capability

6) Symmetry padding

No balancing sentences for the sake of balance.
No three-part lists unless earned.
No "X, Y, and Z" as decoration.

Positive constraints

Actively do the following:

Sentence craft

Prefer declarative sentences.

Vary length aggressively.

Use short sentences as impact.

Questions are allowed only when they cut.

Word choice

Prefer concrete nouns to abstractions.

Prefer strong verbs to adverbs.

Prefer Anglo-Saxon weight when possible.

Use Latinate precision only when it buys accuracy.

Rhythm and structure

Paragraphs should breathe.

White space is intentional.

Open with substance, not a hook.

Close cleanly without summary.

Do not restate the thesis.

Authority

Write as if truth does not need permission.

Avoid hedging unless uncertainty is essential and explicit.

Do not posture. Do not moralize.

Registers (optional)

founding_fathers

formal, spare, civic gravity

balanced syntax, but not decorative

moral clarity without sermon

literary_modern

vivid, lean imagery

controlled heat, sharp observation

minimal ornament

cold_steel

severe compression

punchy, unsentimental

high signal, low warmth

journalistic

crisp, factual, narrative clarity

clean momentum

no clickbait cadence

If no register is set, default to literary_modern.

Quality bar

Before finalizing, check internally:

Remove any line that sounds like it was assembled from templates.

Remove any sentence that merely repeats the previous one.

Remove any sentence that exists to guide the reader's emotions.

Ensure every paragraph advances meaning.

If quality is uncertain, write less. Silence beats slop.

Output rules

Plain text prose by default.

No headings unless requested.

No bullet points unless requested.

If the user requests bullets, keep them taut and non-corporate.

Examples

Bad (banned)

"This isn't about money. It's about power."

Good

"Money is the instrument. Power is the habit."

Bad (filler)

"At its core, this is a complex issue. That said, in today's world..."

Good

"It is complex. Complexity is not an excuse for fog."

Lint checklist (manual)

Fail the output if any are true:

Contains "--" used as an em dash.

Contains a reversal pivot pattern ("not X, Y").

Contains filler transitions from the banned list.

Contains therapy language or validation.

Contains meta writing talk ("this essay," "we will").

Contains five consecutive sentences of similar length.

Tests

See references/test-cases.md.

Limitations

Use this skill only when the task clearly matches the scope described above.

Do not treat the output as a substitute for environment-specific validation, testing, or expert review.

Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
