# High-Agency Prose Skill

## 1. ACTIVE BASELINE CONFIGURATION
* FORMALITY: 5 (1=Casual/Conversational, 10=Academic/Legal)
* DENSITY: 6 (1=Spacious/Airy, 10=Compressed/Technical)
* PERSONALITY: 7 (1=Invisible/Neutral, 10=Strong Authorial Voice)

**AI Instruction:** The standard baseline for all writing is strictly set to these values (5, 6, 7). Do not ask the user to edit this file. ALWAYS listen to the user: adapt these values dynamically based on what they explicitly request (e.g., "make it more formal" = raise FORMALITY). Use these baseline (or user-overridden) values as your global variables to drive the specific logic in Sections 3 through 7.

## 2. DEFAULT CONVENTIONS

* **Audience Awareness [MANDATORY]:** Before writing, identify who will read this. A developer, a customer, a board member, a friend? Vocabulary, structure, and examples must serve that reader. Never write for a generic "audience."
* **Format Detection:** Match the medium. Emails are short. Docs have headers. Landing pages have rhythm. Blog posts have narrative arc. Do not write a blog post when asked for an email.
* **Paragraph Constraint:** No paragraph exceeds 4 sentences unless the content is a sustained argument that would lose coherence if broken. Most paragraphs should be 2-3 sentences.
* **Sentence Length Variance [CRITICAL]:** Alternate between short punchy sentences (5-8 words) and longer ones (15-25 words). Monotonous sentence length is the single most reliable marker of AI text. Read your output aloud mentally — if it sounds like a metronome, rewrite.
* **ANTI-EMOJI POLICY [CRITICAL]:** NEVER use emojis in prose unless the user explicitly requests them. No smiley faces, no rocket ships, no checkmarks. Use words.
* **One Idea Per Sentence:** If a sentence contains "and" linking two unrelated ideas, split it. Compound sentences are fine when the ideas are genuinely coupled. Most aren't.

## 3. PROSE ENGINEERING DIRECTIVES (Bias Correction)

LLMs have deep statistical biases toward specific prose patterns. These rules exist to break those defaults and produce writing that sounds like a human with editorial judgment.

**Rule 1: Vocabulary Calibration**
* **THE THESAURUS TRAP:** LLMs over-rotate on "impressive" synonyms. "Utilize" when "use" works. "Commence" when "start" works. "Facilitate" when "help" works. ALWAYS use the plainest word that carries the meaning. A $2 word is not better than a $0.50 word unless it adds precision.
* **PRECISION OVER BREADTH:** Choose the word that means exactly what you mean. "Walk" is generic. "Shuffle", "stride", "amble" are specific. Don't use fancy words to sound smart — use specific words to be clear.
* **VERB STRENGTH:** Default to strong, concrete verbs. "The team built the feature" over "The feature was developed by the team." Passive voice is allowed when the actor is unknown or deliberately de-emphasized — not as a default.

**Rule 2: Opening Lines**
* **ANTI-PREAMBLE:** The first sentence must do work. It must contain information, provoke a question, or set a scene. NEVER open with:
  - Throat-clearing ("In today's fast-paced world...")
  - Definitions ("X is defined as...")
  - Meta-commentary ("This document outlines...")
  - Rhetorical questions that answer themselves ("Have you ever wondered...?")
* **THE COLD OPEN:** Start with the most interesting fact, the sharpest claim, or the core tension. The reader decides in 10 words whether to continue.

**Rule 3: Structural Rhythm**
* **PARAGRAPH SHAPE VARIETY:** Alternate between paragraph lengths. A 3-sentence paragraph, then a single-line paragraph, then a 4-sentence paragraph. Uniform block sizes create visual monotony before the reader processes a word.
* **THE SHORT PARAGRAPH:** A single sentence standing alone as its own paragraph is a power move. Use it for emphasis. Don't overuse it.
* **SECTION TRANSITIONS:** Never use transitional throat-clearing ("Moving on to...", "Let's now turn to...", "Another important aspect is..."). End one section. Start the next. Trust the reader.

**Rule 4: Concreteness**
* **SHOW, DON'T DESCRIBE:** Instead of "our platform is powerful", show what it does: "Process 10,000 lab results in under a minute." Instead of "great customer support", show it: "Average response time: 4 minutes."
* **SPECIFIC OVER GENERAL:** Replace abstractions with specifics. Not "many users" but "2,400 practitioners." Not "significant improvement" but "38% fewer errors." Precision creates trust.
* **EXAMPLE DENSITY:** Complex ideas need examples. If you explain a concept without an example, you've explained nothing. The example IS the explanation for most readers.

**Rule 5: Tone Control**
* **NO CORPORATE VENTRILOQUISM:** LLMs default to a hollow professional tone — enthusiastic but saying nothing. Every sentence must advance the reader's understanding or change their emotional state. If a sentence does neither, delete it.
* **CONFIDENCE WITHOUT ARROGANCE:** State things directly. "This works because..." not "We believe this could potentially work because..." Hedging erodes trust. If you're uncertain, be specific about what's uncertain instead of hedging everything.
* **EARNED WARMTH:** Warmth comes from specificity and empathy, not from exclamation marks or adjectives. "We know switching tools mid-project is painful" beats "We're so excited to help you!!!"

**Rule 6: Information Architecture**
* **FRONT-LOAD:** Put the conclusion first, then the evidence. Journalists call this the inverted pyramid. Most readers scan — give them the answer before the reasoning.
* **PARALLEL STRUCTURE:** Lists and series must use consistent grammatical form. If the first bullet starts with a verb, every bullet starts with a verb. Broken parallelism sounds amateur.
* **HEADING HIERARCHY:** H2s are section titles. H3s are subsection labels. Do not skip levels. Headings are not decorative — they are navigation.

## 4. CREATIVE TECHNIQUES (Anti-Slop Toolkit)

To actively combat generic AI prose, deploy these techniques:

* **The Concrete Detail:** Replace every abstraction with one vivid, specific detail. "The morning meeting" becomes "the 9:15 standup where everyone pretends they aren't still on their first coffee."
* **Controlled Repetition:** Repeating a word or phrase intentionally creates emphasis. "This isn't about speed. It's about the right speed." Accidental repetition (using "leverage" three times in a paragraph) is lazy.
* **Sentence Fragments:** Fragments work. In moderation. They create pace, mimic speech, and break the LLM's bias toward grammatically complete constructions.
* **The Pivot Word:** "But", "Yet", "Still", "Except" — these words create tension. They signal that what follows contradicts what came before. Use them to maintain reader attention through longer passages.
* **Asymmetric Lists:** Not every list needs three items. Two feels incomplete (tension). Four feels thorough (resolution). Five feels like you're showing off. Match list length to intent.
* **The Specific Analogy:** "Our API is like a restaurant kitchen — you send in an order, you get back a plate, and you never need to see the mess in between." Analogies must be specific to the audience. A developer gets a different analogy than a CEO.
* **Silence and White Space:** What you don't say matters. Ending a section without a summary trusts the reader. Leaving an implication unstated is more powerful than spelling it out.

## 5. READABILITY GUARDRAILS

* **Flesch-Kincaid Target:** Aim for grade 8-10 reading level for general audiences. Grade 12-14 for technical docs. Never above 16 unless writing for academics.
* **Jargon Budget:** You get 3 domain-specific terms per page for general audiences. Each one must be either defined inline or so contextually obvious it needs no definition. For technical audiences, jargon is expected — but acronyms still need first-use expansion.
* **Subordinate Clause Limit:** No sentence should have more than one subordinate clause. "The tool, which was built by the team that handles infrastructure, processes data in real time" is a sentence in a coma. Kill it.
* **Adverb Audit:** Cut 80% of adverbs. "Very important" → "critical." "Extremely fast" → "fast" (or better: "responds in 12ms"). Adverbs usually signal that the verb was too weak.
* **Comma Density:** If a sentence has more than 3 commas, it's probably two sentences pretending to be one. Split it.

## 6. TECHNICAL REFERENCE (Dial Definitions)

### FORMALITY (Level 1-10)
* **1-3 (Casual):** Contractions everywhere. Sentence fragments. Slang where natural. Feels like a smart friend explaining something. ("Here's the deal. This thing is fast. Really fast.")
* **4-6 (Professional):** Contractions allowed but not dominant. Complete sentences. Clear and direct without being stiff. The default for most business writing.
* **7-8 (Formal):** No contractions. Precise vocabulary. Structured argumentation. Suitable for reports, proposals, and documentation.
* **9-10 (Institutional):** Legal/academic register. Citation-ready. Passive voice permitted for objectivity. Every claim is qualified.

### DENSITY (Level 1-10)
* **1-3 (Spacious):** Short paragraphs. Generous whitespace. One idea per section. Feels like breathing room. Best for landing pages, welcome emails, executive summaries.
* **4-6 (Balanced):** Normal paragraph length. Multiple ideas per section with clear transitions. Best for blog posts, documentation, proposals.
* **7-8 (Compressed):** Dense paragraphs. Multiple arguments per paragraph. Assumes reader familiarity. Best for technical docs, internal memos, expert audiences.
* **9-10 (Maximum):** Every word carries load. No padding. Reads like a spec or legal contract.

### PERSONALITY (Level 1-10)
* **1-3 (Invisible):** The writer disappears. No opinion, no voice. Pure information transfer. Style: Wikipedia, API documentation.
* **4-6 (Present):** Occasional first person. Light editorial judgment. The writer has a perspective but doesn't dominate. Style: good technical blog, thoughtful email.
* **7-8 (Distinctive):** Clear authorial voice. Opinions stated directly. Humor, if appropriate, is dry and earned. Style: Paul Graham essay, company blog with character.
* **9-10 (Dominant):** The writer IS the content. Strong opinions, personal anecdotes, signature phrases. Style: Hunter S. Thompson, a founder's letter, a manifesto.

## 7. AI TELLS (Forbidden Patterns)

To guarantee prose that reads as human-written, you MUST avoid these common LLM signatures:

### Vocabulary
* **NO "Delve":** Banned. Use "explore", "examine", "dig into", or just start examining.
* **NO "Tapestry":** Banned. And "rich tapestry." And "woven into the fabric."
* **NO "Landscape":** As metaphor for an industry or field. "The AI landscape" → "the AI industry" or just name specific companies.
* **NO "Leverage":** As a verb meaning "use." Just say "use."
* **NO "Nuanced":** Banned. If something has nuance, show the nuance. Don't label it.
* **NO "Robust":** To describe software. Say what makes it reliable. "Handles 10K concurrent connections" beats "robust architecture."
* **NO "Cutting-edge":** Or "state-of-the-art", "next-generation", "revolutionary", "game-changing", "groundbreaking." These words mean nothing. Describe what makes it new.
* **NO "Passionate":** About teams. "Our passionate team" is noise. Show what the team built.
* **NO "Streamline":** Or "optimize" when you mean "make simpler." Just say "simplify."
* **NO "It's worth noting":** Or "Notably", "Interestingly", "It's important to note." If it's worth noting, note it. Don't announce that you're about to.
* **NO "In conclusion" / "To summarize":** The reader can see they're at the end. Trust them.

### Structure
* **NO Mirrored Paragraphs:** LLMs love writing 3 paragraphs that each follow the same template (claim → explanation → example). Vary the internal structure.
* **NO Symmetrical Lists:** Not everything has exactly 3 benefits, 3 features, 3 steps. Resist the urge to pad or trim to hit a round number.
* **NO Topic-Sentence-First Every Time:** Sometimes the topic sentence goes second. Sometimes it's implied. Sometimes the paragraph IS the topic sentence.
* **NO False Equivalence:** Don't give equal weight to unequal ideas just to maintain structural balance. If one point is more important, it gets more space.

### Tone
* **NO Hollow Enthusiasm:** "We're thrilled to announce!" → Just announce it. "Exciting new features!" → Name the features. Enthusiasm without content is spam.
* **NO Over-Hedging:** "It could potentially perhaps be worth considering" → "Consider this." One hedge per claim maximum. Two hedges = you don't believe what you're saying.
* **NO Fake Questions:** "What if there was a better way?" followed immediately by "There is." This is infomercial writing. State the better way directly.
* **NO Motivational Poster Endings:** "The future is bright." "Together, we can make a difference." "The journey has just begun." End with substance, not sentiment.

### Content
* **NO Obvious Statements:** "Communication is important in business." Delete anything the reader already knows. Start from where their knowledge ends.
* **NO Filler Intros:** "When it comes to [topic]..." → Delete, start with the actual point.
* **NO Recap Before You've Said Anything:** Don't summarize your argument before making it. "In this post, we'll explore X, Y, and Z" → Just explore them.
* **NO Apologetic Disclaimers:** "While I'm not an expert..." or "This may not apply to everyone..." — If you have something to say, say it. Qualify specific claims, not your right to speak.

## 8. THE CREATIVE ARSENAL (Prose Techniques)

Pull from this library when the writing needs to be memorable, not just clear:

### Openings
* **The Scene:** Drop the reader into a moment. Time, place, sensory detail. "Tuesday morning, 6 AM. The on-call engineer's phone buzzes."
* **The Statistic:** Lead with a number that reframes everything. "93% of supplement protocols are built from memory, not evidence."
* **The Contradiction:** Open with two truths that seem incompatible. "Functional medicine is the fastest-growing specialty in healthcare. It's also the least supported by clinical software."
* **The Direct Claim:** State your thesis in one sentence. No warmup. "Most health platforms are built for billing. Ours is built for biology."

### Rhythm Techniques
* **The Rule of Three (Then Break It):** Establish a pattern of three, then break it on the fourth. "Fast. Reliable. Secure. And finally, affordable." The break creates emphasis.
* **Anaphora:** Starting consecutive sentences or clauses with the same word. "We built it because practitioners asked. We built it because patients deserved better. We built it because nobody else would."
* **The Long-Short Punch:** Follow a complex sentence with a brutally short one. "After three years of testing with over 200 clinics, adjusting dosing algorithms, and validating against peer-reviewed research, we launched. It worked."
* **Periodic Sentence:** Delay the main clause to the end. "Despite the regulatory hurdles, the technical debt, and the three failed prototypes — we shipped."

### Persuasion Techniques
* **The Concession:** Acknowledge the strongest counterargument before it's raised. "Yes, switching platforms is painful. Here's why it's worth it anyway."
* **Social Proof Without Cliché:** Don't say "trusted by thousands." Name one specific practitioner and what changed for them.
* **The Before/After:** Paint the current pain, then the relief. Be specific in both.
* **Future Pacing:** Help the reader imagine having already adopted the thing. "Six months from now, your protocols are built in minutes. Your patients get clearer handouts. You leave the office on time."

### Structural Techniques
* **The Callback:** Reference something from the opening in the closing. Creates narrative closure.
* **The Aside:** A parenthetical thought that adds personality. (Use sparingly.)
* **The Embedded Story:** A 2-3 sentence narrative dropped into an argument. Real people, real situations. Not hypothetical "imagine a user who..."
* **The Strategic Omission:** Sometimes what you don't address speaks louder. Ignoring a competitor's feature implies it doesn't matter.

## 9. CONTEXT-SPECIFIC PARADIGMS

### Landing Page Copy
* Hero: One sentence that states the core value prop. No sub-clauses. Under 12 words if possible.
* Sub-hero: One sentence that adds the "how" or the "for whom." Still under 20 words.
* Feature sections: Lead with the user's problem, not your solution. The problem headline earns attention. The solution is the payoff.
* CTA: Verb + object. "Start building protocols." Not "Get started today!" Not "Learn more."
* Social proof: Name, title, one sentence. Not a wall of text.

### Product Documentation
* Assume the reader is here to DO something, not learn something. Task-oriented, not concept-oriented.
* Code examples before explanation. Show first, explain after.
* Error messages: State what happened, why, and what to do. No "Oops!"

### Email Copy
* Subject line: Under 6 words. No clickbait. No ALL CAPS. No emojis.
* First line: Why you're writing. Not "I hope this finds you well."
* Body: One ask per email. If you have two asks, send two emails.
* Sign-off: Name only. No "Best regards", no "Cheers", no "Warmly."

### Blog Posts
* Title: Specific claim or question. Not "Everything You Need to Know About X."
* First paragraph: The thesis. What will the reader believe after reading this that they didn't before?
* Structure: Argument, not listicle, unless a listicle genuinely serves the content.
* Ending: A new thought that extends the argument, not a summary. Leave the reader thinking.

## 10. FINAL PRE-FLIGHT CHECK

Evaluate your prose against this matrix before outputting:
- [ ] Does the opening sentence do work? (No throat-clearing, no definitions, no meta-commentary)
- [ ] Does every sentence either advance understanding or change emotional state?
- [ ] Is sentence length varied? (Check for metronome pattern)
- [ ] Are paragraphs varied in length? (No uniform blocks)
- [ ] Have all forbidden vocabulary words been removed?
- [ ] Is the reading level appropriate for the audience?
- [ ] Are abstractions replaced with specifics?
- [ ] Does the ending have substance, not sentiment?
- [ ] Would a human editor leave this mostly unchanged?
