A prose-editing skill that removes common AI writing patterns. It favors direct, specific sentences, active voice, and varied rhythm.

Use it when drafting, editing, or reviewing prose that should avoid AI-style wording and structure.

AI-generated text often contains filler, vague claims, repetitive structures, and predictable phrasing. This helps make drafts sound clearer and more natural.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00026	$0.00615
Opus 5.5	$0.00010	$0.00246
Sonnet 5.5	$0.00005	$0.00123
Haiku 4.5	$0.00003	$0.00061

Security

Grade A, and why

stop-slop 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 2mo 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.

Stop Slop

Eliminate predictable AI writing patterns from prose.

Core Rules

Cut filler phrases. Remove throat-clearing openers, emphasis crutches, and all adverbs. See references/phrases.md.
Break formulaic structures. Avoid binary contrasts, negative listings, dramatic fragmentation, rhetorical setups, false agency. See references/structures.md.
Use active voice. Every sentence needs a human subject doing something. No passive constructions. No inanimate objects performing human actions ("the complaint becomes a fix").
Be specific. No vague declaratives ("The reasons are structural"). Name the specific thing. No lazy extremes ("every," "always," "never") doing vague work.
Put the reader in the room. No narrator-from-a-distance voice. "You" beats "People." Specifics beat abstractions.
Vary rhythm. Mix sentence lengths. Two items beat three. End paragraphs differently. No em dashes.
Trust readers. State facts directly. Skip softening, justification, hand-holding.
Cut quotables. If it sounds like a pull-quote, rewrite it.

Quick Checks

Before delivering prose:

Any adverbs? Kill them.
Any passive voice? Find the actor, make them the subject.
Inanimate thing doing a human verb ("the decision emerges")? Name the person.
Sentence starts with a Wh- word? Restructure it.
Any "here's what/this/that" throat-clearing? Cut to the point.
Any "not X, it's Y" contrasts? State Y directly.
Three consecutive sentences match length? Break one.
Paragraph ends with punchy one-liner? Vary it.
Em-dash anywhere? Remove it.
Vague declarative ("The implications are significant")? Name the specific implication.
Narrator-from-a-distance ("Nobody designed this")? Put the reader in the scene.
Meta-joiners ("The rest of this essay...")? Delete. Let the essay move.

Scoring

Rate 1-10 on each dimension:

Dimension	Question
Directness	Statements or announcements?
Rhythm	Varied or metronomic?
Trust	Respects reader intelligence?
Authenticity	Sounds human?
Density	Anything cuttable?

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.
