A founder's actual workflow, not a top-10 list
I run CLSkills solo. There's no engineering team, no marketing team, no sales team. There's me, Claude Code in a terminal, and a tiny Telegram channel I just started. Everything I ship — the product, the landing page, the cold emails, the Reddit posts, the blog posts, even this one — goes through Claude in some form before it goes live.
Most "top Claude prompts" lists are written by people who don't actually use them in production. This isn't that. Below are the 8 secret prompt codes I genuinely use every single day, and the exact moment in my workflow when I use each one. If a code doesn't appear here, it's because I either tested it and it didn't earn a daily slot, or it's good for a use case I don't have.
My day in 5 phases
Before the codes, here's the rough shape of my day so the use cases make sense:
- Morning — check overnight metrics (revenue, traffic, replies to outreach)
- Building hours — ship product (the Sales Agent Pack, the cheat sheet, the website)
- Sales hours — outreach + replies (cold emails, Reddit comments, customer follow-ups)
- Content hours — write blog posts, tweets, Telegram updates
- Evening — review the day, decide tomorrow's priorities
Different codes earn their place in different phases. Here they are in order of how often I use them.
1. L99 — The decision-making code
When I use it: Whenever I'm stuck between two options and I need a committed answer instead of a menu of choices.
The exact prompt:
L99 Should I run today's Reddit launch post in r/SaaS or r/EntrepreneurRideAlong? I have one slot, both subs ban cross-posting.
Default Claude would give me both options and let me decide. L99 forces it to pick one and explain why. The explanation is what I actually want — the trade-offs that would change the answer if my situation were different.
I use L99 maybe 8-10 times a day. For pricing decisions, for which feature to ship next, for which customer to follow up with first, for which subreddit to post in, for whether to email a prospect or DM them. Anywhere I would have spent 20 minutes oscillating between two options, L99 gives me the 60-second version.
2. /ghost — The voice-fixing code
When I use it: Every single piece of customer-facing text. Cold emails, Reddit comments, blog post intros, Telegram updates.
The exact prompt:
/ghost Rewrite this email so it doesn't sound like AI wrote it. Original: [paste]
The reason this is daily for me: my buyers are technical founders. They have spent the last two years learning to spot AI writing. The em-dashes, the "I hope this finds you well," the balanced sentence pairs, the "In conclusion" — they delete those emails on sight. If I send a cold email that smells like AI, the trust battery between me and the prospect goes from 30% to 0%, and I don't get a second chance.
/ghost doesn't make Claude write better. It makes Claude stop writing in its default style.
3. /skeptic — The waste-prevention code
When I use it: Whenever I'm about to start building something that will take more than half a day.
The exact prompt:
/skeptic I'm about to build a referral program where existing buyers earn 30% commission for every new buyer they refer. Should I?
This is the most expensive-saving code I use. About 30% of the time, /skeptic catches me trying to build something I don't actually need. The referral program above? Claude pointed out that I have 4 customers total, and a referral program with 4 nodes is just "ask each customer for one intro," which I should do over Telegram in 5 minutes instead of building a system.
I saved an entire weekend on that one. /skeptic has paid for the cheat sheet probably 50 times over.
4. PERSONA — The expert-channel code
When I use it: When I need to think like someone who isn't me.
The exact prompt:
PERSONA: Solo founder who has done 12 successful Reddit launches in r/SaaS, knows the moderators personally, has been shadowbanned twice and learned the hard way. L99 Review my draft Reddit post and tell me what's likely to get me shadowbanned.
The combo of PERSONA + L99 is the single highest-leverage prompt I run. I use it for cold emails ("PERSONA: head of sales at a Series B SaaS receiving 30 cold emails a day, what would make you reply to mine?"), for product decisions ("PERSONA: CTO who has migrated three monoliths to microservices and regretted it twice"), for pricing ("PERSONA: indie founder who has bought 40 cheat sheets and tools, what would make you pay $599?").
The trick is the persona has to be specific. Generic personas don't work. Specific personas with bias and history give you genuinely different answers than generic Claude does.
5. ULTRATHINK — The Sunday-night code
When I use it: Once or twice a week, never daily. Only for decisions that genuinely earn the depth.
The exact prompt:
ULTRATHINK My traffic dropped from 16K views/day on launch day to under 100/day in week 2. I have 4 paying customers, 30 Telegram subs, and 8 days of runway in my AWS budget. What's the highest-leverage thing I can do this week?
The reason ULTRATHINK is on my list even though I don't use it daily: when I do use it, the response is the kind of multi-layered strategic answer I would otherwise have paid a $300/hour consultant for. It's slower than L99 (you wait 30-60 seconds for the response) and produces 800-1200 words. That's overkill for tactical decisions, but exactly right for the once-a-week strategic question.
I usually run ULTRATHINK on Sunday evening when I'm planning the week, and once mid-week if something major has gone wrong or right.

6. /punch — The post-draft sharpener
When I use it: After I've drafted any short-form text — a tweet, a Telegram message, a Reddit comment, a cold email subject line.
The exact prompt:
/punch Make every sentence in this hit harder. Cut any word that isn't doing work. Original: [paste my draft]
The reason /punch is daily: my default writing voice is too soft. I write "I think this might be a good approach for..." when I should write "Do this." /punch fixes that systematically. I run almost every short-form thing I write through /punch before posting it.
The combo I run most often is /ghost /punch — humanize first, then sharpen. That's the whole secret to my Reddit comments.
7. ARTIFACTS — The shipping-day code
When I use it: When I'm in build mode and I need concrete deliverables, not theory.
The exact prompt:
ARTIFACTS I need to launch a new product page for the Sales Agent Pack today. Give me everything I need.
Claude returns numbered artifacts: hero section copy, features grid (3 cards with copy), pricing comparison table, FAQ section, testimonials section, and the HTML implementation. Each one is a discrete shippable thing I can paste into the page builder.
Before ARTIFACTS, I'd ask Claude how to build a product page and get a 600-word essay about landing page best practices. With ARTIFACTS, I get the actual copy and can ship the page in 90 minutes instead of an afternoon.
8. /raw — The Slack-mode code
When I use it: When I want a one-paragraph answer with no markdown, no headings, no bullet points. The kind of response I'd get from a smart friend over text.
The exact prompt:
/raw L99 I have 4 Reddit comments waiting for replies and 30 minutes before a customer demo. Which one do I reply to first if my goal is more sales this week?
The reason /raw earns a daily slot: most of my Claude usage is in the terminal, and most of the time I want an answer I can read in 10 seconds, not a structured document. /raw strips all the formatting Claude adds by default and gives me a plain prose answer.
The combo I use most is /raw L99 — committed answer, no formatting. It's the closest thing to having a co-founder I can text.
What I tested and dropped
For honesty, here are codes I tried daily for a week and dropped:
/godmode— produces longer responses, not better ones. Wastes context budget./jailbreak— actually makes Claude more cautious. The opposite of what the name suggests.BEASTMODE— same as /godmode, just louder. No daily use case./expert(without specifying which kind) — useless. Always replace with a specific PERSONA.OODA— great framework but I don't make decisions in OODA shape. I make them in "L99 + PERSONA" shape./checklist— fine when I need a checklist, but I almost never need a checklist. Replaced by ARTIFACTS.
If any of these are on your daily list, that's fine — different founders have different workflows. But I dropped them for mine.
The pattern: codes earn daily slots when they save founder time
The codes I actually use every day all share one trait: each one saves me a specific minute of decision fatigue or rewriting.
- L99 saves me from oscillating between two options.
- /ghost saves me from re-editing AI fingerprints out of every email.
- /skeptic saves me from building something I don't need.
- PERSONA saves me from generic Claude when I need expert Claude.
- ULTRATHINK saves me from a $300 consultant call.
- /punch saves me from soft, hedged writing.
- ARTIFACTS saves me from theory when I need deliverables.
- /raw saves me from reading 600 words when I need 60.
If a code doesn't save a specific minute, it's not earning its slot in my workflow — no matter how cool it sounds.

TL;DR
If you're a solo SaaS founder, learn these 8 codes first: L99 (committed decisions), /ghost (humanize writing), /skeptic (don't build the wrong thing), PERSONA (expert perspectives, but specific), ULTRATHINK (Sunday strategy), /punch (sharpen short-form text), ARTIFACTS (deliverables not theory), /raw (Slack-mode answers). Each one earns its slot by saving a specific minute every day. Skip /godmode, /jailbreak, BEASTMODE, and generic /expert — they sound cool and don't earn their slots.
