How I Use Reusable Claude Skill Files to Run My Daily Work

Posted on Oct 30 • Originally published at heyjoekurt.medium.com

Most people who use Claude every day have a messy folder or spreadsheet full of saved prompts somewhere on their laptop.

I had one too. It had over a hundred prompts I copied from articles and threads, and I almost never opened it. Every morning I still opened a blank chat, typed a rough paragraph explaining what I needed, and spent the next twenty minutes arguing with the output.

One draft came back sounding like a stiff corporate press release. Another forgot my pricing model. By the twelfth message in the same thread, two annoying things always happened at once: Claude started losing track of instructions from the top of the chat, and I burned straight through a huge chunk of my 5-hour session limit.

Most people don't realize how token math works inside a long AI chat. Every time you send message fifteen in a messy thread, Claude re-reads messages one through fourteen all over again. Fixing a weak prompt through twenty rounds of trial and error is the fastest way to hit the usage wall by mid-afternoon.

Everything got easier the week I threw out my prompt list and switched to small, single-purpose Markdown skill files.

Why Prompts Break Down (and Plain Files Work) A normal prompt is just a wish. You type "write a client proposal from these notes" and force Claude to guess the structure, the pricing layout, the revision boundaries, and the tone all at the same time. When it guesses wrong, you spend six more messages fixing it.

A skill file works like a repeatable checklist for one specific job you do every week.

Instead of keeping everything inside one giant instruction block, I split my setup into two layers:

First, two tiny root files sit permanently inside my Claude Project (or local Claude Cowork folder). One holds my work context: what I do, who buys from me, my offers, real proof numbers, and my 90-day goal. The second holds my plain-English writing rules and blocks sixty common AI clichés so nothing comes back sounding robotic.

Second, I keep twenty small Markdown files organized by the actual parts of a workweek: writing, client work, offers and sales, strategy decisions, and daily operations. When I finish a call or need to price a project, I drop in that one small file, paste my rough notes, and get a finished draft on turn one.

Three Skill Files You Can Copy Today You do not need any coding setup or special plugins to run this. You can save each block below as a plain.md text file on your computer, drag it into Claude Projects or Claude Cowork, or simply paste it above your rough notes in a fresh chat.

Here are the three workflows that save me the most time every single week.

Turning Messy Call Notes Into a Real Action Plan Right after a client call, a discovery chat, or a team meeting, you usually have forty lines of messy bullet points or a raw transcript. If you just ask Claude to summarize it, you get a polite paragraph that hides who actually owes what by Friday.

Save this as 08_call_to_action.md and paste your raw notes underneath it:

Purpose: Turn raw call notes or a meeting transcript into clear decisions, owners, hidden signals, and a short recap email.

Intake check: Run right away on the pasted notes. Only pause to ask who I am in the transcript if speaker names are unclear.

Separate real decisions that both sides agreed on from ideas that were only casually mentioned. Build a four-column action list showing the task, the owner, the exact deadline, and what is waiting on it. Flag between-the-lines signals: budget clues, unspoken hesitations, or open questions nobody answered on the call. Draft a plain-English recap email under 170 words locking in what was agreed and who does what next. Quality check: Use short paragraphs, zero corporate buzzwords, and concrete dates instead of vague words like "soon."

Turning Discovery Notes Into a 3-Option Proposal Sending a single flat price after a good client call forces the buyer into a yes-or-no corner. Even worse, sending a loose one-page quote without clear boundaries almost always leads to unpaid extra revisions three weeks later.

Save this as 06_proposal_scope.md and feed it your call bullets plus your target middle price:

Purpose: Turn rough project notes into a clean proposal with three clear options and firm scope boundaries.

Intake check: Ask me for any missing piece from these three items before writing: what outcome the client wants, the rough timeline, and my target price for the standard middle option.

Open with the situation and goal written in the client's own plain words so they see immediately that I listened. Build three clear tiers: Option 1 covers the essential core fix at 1x price, Option 2 covers the complete recommended outcome at roughly 1.5x price, and Option 3 covers fast-track or full done-for-you delivery at roughly 2.2x price. Write an explicit Scope Boundaries section spelling out what is included, the exact revision cap, turnaround times, and what counts as a paid add-on.

Close with the timeline, payment split, and a simple one-step reply so they can approve today, plus a four-sentence cover email. Running a Ruthless Pre-Mortem Before You Spend Money or Weeks Building Chat assistants are trained to be agreeable. If you pitch a weak project idea, a risky hire, or an underpriced service, default Claude will cheerfully tell you it sounds promising and help you waste six weeks building it.

Before I commit real hours or cash to a new plan, I run 13_premortem.md so Claude pushes back like a skeptical partner:

Purpose: Assume my plan failed six months from today and expose the real reasons before I spend time or money.

Intake check: Ask me to state my plan, how many hours or dollars I am betting on it, and what success looks like in ninety days.

Fast-forward six months and assume this plan flopped completely. Do not soften the feedback or flatter me. Rank the five most likely causes of failure based on how often they happen and how much damage they cause (such as having no distribution plan, pricing below platform fees, or spending weeks building before testing demand). Point out wishful assumptions in my plan that I am treating as guaranteed without proof. Give me one cheap 48-hour test I can run this week to prove strangers actually want this before I build the whole thing. How to Keep Your Setup Fast and Clean If you build your own folder like this, keep one simple rule: never dump all twenty workflows into a single chat at the same time.

Keep only your short context memory and your voice rules loaded all the time. Pull in individual workflow files only for the exact task sitting in front of you, and start a fresh chat whenever you switch from writing a client proposal to reviewing weekly numbers. Your outputs stay sharp, your voice stays consistent, and your usage meter barely moves.

If you want to build this yourself, start with the three files above and add one new.md file every time you catch yourself typing the same instructions twice.

And if you want my complete folder already built and ready to drop into Claude Projects, Claude Cowork, or a 1-click offline browser dashboard, I packaged all 20 workflow files plus the 2 core memory and human-voice files into The Claude Work and Business OS (or grab my free 48-Hour Launch Checklist first if you are shipping a new offer this week).
