Write Sales Copy That Converts Without Sounding Like AI

Where this fits

You're building an agent that drafts launch emails or landing pages. The first output comes back polished but vague—full of "revolutionary" and "game-changing," with no proof or specifics. Your user needs copy that sells through clarity, not hype. The sales-copy skill from EveryDay-Writer enforces a dependency chain of anti-AI rules, proof standards, and a defined voice profile, so your agent produces conversion-focused copy that reads human and credible.

Why agents benefit

• Enforces anti-AI rules automatically: The skill reads core/anti-ai-rules.md and ai_slop_commandments.md before writing, preventing generic filler and fabrication.
• Maintains a consistent voice: It loads a voice profile and stops if onboarding isn't complete, ensuring every piece matches the user's brand personality.
• Demands proof and specificity: Copy must include concrete claims and evidence, not empty superlatives—so the agent learns to ask for or infer real data.
• Works across formats: Handles sales pages, email sequences, and direct-response copy with the same standards, reducing prompt engineering.
• Prevents over-correction: Rules 9 and 10 in the anti-AI rules stop the agent from swinging too far into robotic, awkward writing.

Practical scenarios

Launch email sequence for a SaaS product

Your agent drafts a 5-email onboarding sequence. The skill ensures each email has a single clear call-to-action, avoids manipulative urgency, and includes specific metrics from the product's changelog instead of vague benefits.

Landing page for a niche B2B service

A consultant wants a page that converts without sounding pushy. The agent uses the voice profile to write in a calm, factual tone, and the proof standards force it to include case studies or testimonials rather than invented social proof.

Direct-response ad for a physical product

Your agent writes a short ad for a kitchen gadget. The skill's anti-fabrication rule stops it from inventing customer quotes or star ratings—instead it compels the agent to ask the user for real reviews or use product specs to build persuasive arguments.

Add it to your agent workflow

Install the skill directly into your agent's skill directory:

npx skills add Deupaxx/EveryDay-Writer --skill sales-copy

Then invoke it in your agent's instructions:

When writing sales copy, load the sales-copy skill and follow its dependency chain. If the voice profile is incomplete, ask the user to complete onboarding before drafting.

Your agent will read the required core files first, then produce copy that meets the writer's standards. For more context on how this skill fits into the broader agent skill ecosystem, see this skill's page.

Compare before adopting

Before you commit, evaluate the skill's freshness (version 0.3.0, still evolving), its quality signals (28 stars, but check recent commits), and whether its strict voice-profile requirement fits your workflow. Compare it with other copywriting skills that might be more flexible but less rigorous. Also test how it handles edge cases—like when the user hasn't provided references or a completed voice profile.

Why it is worth tracking

The skill's enforcement of anti-AI rules and proof standards is a differentiator—most copywriting skills don't enforce a full dependency chain. Its version history shows active maintenance, and the author's focus on clarity over manipulation aligns with current AI-content best practices. Re-evaluate this skill after major updates to see if it adds new formats or relaxes constraints without losing rigor.
