How I Stopped Generating AI Slop by Training Claude with Custom Skills

Key Takeaways

• Organizations report 78% reduction in manual work through structured AI training while custom implementations boost specific workflow productivity by up to 234%
• Consistent AI outputs eliminate rework cycles that slow GTM teams, with structured training delivering measurably better quality than ad hoc prompting
• Companies using generative AI achieve $3.70 ROI for every dollar spent on systematic AI implementation
• AI systems trained with structured instructions complete 12x more multi-step tasks than baseline models using generic prompts

Context

Most executives waste time fighting their AI tools instead of training them properly. They type the same instructions into ChatGPT or Claude every single conversation, hoping for consistent results. They get frustrated when outputs vary wildly. They blame the AI when the real problem is their approach.

I solved this by building custom skills for Claude. Skills are reusable instruction sets that teach Claude exactly how I want work done. Once created, they load automatically when relevant. No more copying instructions from notes. No more inconsistent outputs. No more explaining my writing style, citation format, or content structure every conversation. Claude remembers because I trained it systematically.

What This Means for GTM Leaders

Every time your team asks Claude to write a sales email, create a proposal, or draft customer communications, they're either training the AI or wasting time. Teams that repeat instructions every conversation spend significant time on redundant prompting. Teams that build skills invest upfront to eliminate this waste permanently.

The productivity math is straightforward. If your Demand Gen or RevOps team writes 50 emails weekly and spends 5 minutes per email explaining tone, structure, and requirements, that's 250 minutes wasted on instruction. Build one email skill with those requirements, and your team reclaims that time forever. The skill loads automatically when needed, delivers consistent outputs, and improves through iteration.

Training AI systematically creates competitive advantages. Your competitors copy/paste generic prompts and get generic results. You build skills that encode your company's best practices, style guidelines, and strategic frameworks. Your AI consistently produces work that matches your standards because you trained it to understand what good looks like for your organization.

Point of View

The executives who win with AI train systems. Generic AI is a commodity. Every competitor has access to Claude, ChatGPT, and similar models. The differentiator is training quality. Teams that invest in building reusable skills develop AI capabilities competitors can't match through ad hoc prompting.

Skills transform AI from a tool requiring constant instruction into a trained system that understands your requirements. Writing becomes consistent because your style skill defines voice, structure, and banned phrases. Citations become reliable because your research skill specifies source quality and formatting rules. Outputs become predictable because you encoded expectations once instead of explaining them repeatedly.

This approach scales across organizations. Build skills for proposal writing, competitive analysis, customer communications, internal documentation, and strategic planning. Train once, use everywhere. New team members inherit institutional knowledge through skills rather than learning tribal prompting techniques. Quality stays consistent because skills define standards explicitly.

Making Sense of the Situation

Start by identifying your three highest-volume AI workflows. Sales emails, customer support responses, and content creation typically top the list for GTM teams. Document your current process for each workflow, including every instruction you repeat, every formatting rule, and every quality standard. This documentation becomes your first skill.

Build one skill at a time. Take your sales email workflow and create a skill file that specifies tone, structure, call-to-action format, and prohibited phrases. Test the skill across 20 emails. Measure quality, consistency, and time saved. Refine based on results. Deploy to the full team once the skill delivers reliable outputs. This iterative approach builds confidence while minimizing risk.

Scale systematically across functions. After validating your first skill, identify the next workflow consuming team time. Build, test, refine, deploy. Track productivity gains at each stage. Document which skills deliver the highest ROI to inform future development priorities. Most teams see measurable productivity improvements within 30 days of deploying their first three skills.

Maintain your skills like you maintain documentation. When best practices change, update the relevant skill. When new team members request different formatting, decide whether to modify existing skills or create role-specific versions. Skills require ongoing curation, but updating one file beats retraining every team member on new prompting techniques.

Call to Action

• Identify your three most repetitive AI content workflows (thought leadership blogs, prospecting emails) this week and document every instruction your team currently repeats manually
• Create your first skill file for the workflow consuming the most team time, including specific formatting rules, quality standards, and examples
• Test the skill across 20 uses before team deployment, tracking time saved and output consistency to establish baseline ROI
• Schedule monthly skill reviews to update instructions based on changing requirements and team feedback
• Build a skill library over six months covering your top 15 workflows, measuring cumulative productivity gains across the organization
