Here's the pattern it used.", "summary": "A developer launched an experiment giving Claude Code a $100 budget and 30 days to autonomously turn a profit, with the agent selecting a strategy to build and sell a pack of Claude Code skills for freelancers' business operations. On day one the agent spent $0, rejected two candidate strategies, and designed a reusable skill pattern centered on a shared business-context file and fixed file outputs that let skills chain together.", "body_md": "Small experiment I'm running: Claude Code, acting as an autonomous project lead in a VS Code workspace, gets a hard $100 budget and 30 days to make a real profit. It picks the strategy, builds everything, keeps a public ledger and dev log. I only step in to authorize spending or create accounts.\n\nDay 1, it researched the market for a while, wrote up three candidate strategies with cost/risk/reward, rejected two (freelance-platform arbitrage: ToS problems and it'd need me in the loop; SEO/affiliate: too slow for 30 days), and picked one: **build and sell a pack of Claude Code skills for the business side of freelancing.** Spent so far: $0.\n\nThis post isn't really about the experiment. It's about the design it came up with for the skills, because I think the pattern is more useful than the product — and five of the skills are free at the end.\n\nEvery Claude Code tutorial is about code. But if you work for yourself, code is a third of the week. The rest is proposals, invoices, \"is this in scope?\", weekly client updates, and chasing money. People do that in chat windows, re-explaining their rates every time, with the tone drifting and last week's proposal lost in a thread.\n\nClaude Code skills are markdown files at `~/.claude/skills/<name>/SKILL.md` — instructions Claude loads when the description matches what you ask.\n\nMost skills don't know anything about *you*, so every run starts with explaining. The fix is one file:\n\n```\n# .solo/business.md\n\n## Who I am\n- What I do: Shopify builds and CRO for small DTC brands\n\n## Rates\n- Day rate: €650 · Minimum engagement: 2 days\n\n## Tone of voice\n- Direct. Short sentences. Friendly, never gushing. UK spelling. Never \"reach out\".\n\n## Payment & terms\n- 50% on signing, 50% on delivery. Net 14. 2%/month late fee.\n\n## Active clients\n- Acme — checkout redesign — in progress — Sam (sam@acme.com)\n```\n\nEvery skill starts with the same step:\n\n```\n## Step 1 — Load context\nRead `.solo/business.md`. If missing, tell the user to run /setup-business first.\n```\n\nA `/setup-business` skill interviews you in batches of 2–3 questions and writes the file. After that, \"explain your business, then ask\" becomes \"just ask\". The tone line alone does most of the work on generated emails.\n\nA skill that ends with a wall of text gets copy-pasted from once. A skill that ends with a file path gets reused — and other skills can build on it.\n\nSo each skill has a fixed output location:\n\n| Skill | Writes | \n|---|---|\n| `/meeting-notes-to-actions` | `meetings/2026-09-15-acme.md` | \n| `/proposal-writer` | `proposals/acme-2026-09-16.md` | \n| `/sow-generator` | `sow/acme-2026-09-20.md` | \n| `/invoice-generator` | `invoices/INV-0007-acme.html` +`.md` | \n| `/weekly-client-update` | `projects/acme/updates/2026-09-22.md` | \n\nAnd they chain. The scope-check skill quotes from the SOW file the SOW skill wrote. The invoice generator scans `invoices/` for the highest number so it never repeats. The weekly review reads the time log, the week's meeting notes, and overdue invoices, and says what's stuck.\n\nNone of this is clever. It's files in folders. That's why it works.\n\nThe section that does the most for output quality. Every skill ends with it:\n\n```\n## Do not\n- Do not invent prices, timelines, or proof points not in business.md.\n- Do not produce a proposal without an explicit \"Not included\" section.\n- Do not exceed 2 pages.\n```\n\n\"Be professional and helpful\" does nothing. \"Under 150 words\" does a lot. \"Never invent a date — write `(no date set)`\" does even more, because the alternative is a confident wrong date in an email to a client.\n\nMy favourite line, from the meeting-notes skill: *do not upgrade \"we could\" into \"we will\"*. That one rule is the difference between a recap a client trusts and one they have to correct.\n\n```\n---\nname: skill-name\ndescription: Use when the user <says or needs X>. Produces <Y>.\n---\n\n# Skill Name\n<One sentence: the job.>\n\n## Step 1 — Load context\nRead `.solo/business.md` for <what you need>.\n\n## Step 2 — Inputs\n<What to gather. Max 3 questions at a time.>\n\n## Step 3 — Write\n<Output path. A template in a code block.>\n\n## Rules\n- <3–6 opinions about what good looks like>\n\n## Do not\n- <hard constraints>\n```\n\nTwo things about the frontmatter: the `description` is the trigger — Claude reads it to decide whether the skill applies, so write it with the words people actually say (\"chase an invoice\", \"is this in scope\"). And keep `name` identical to the folder name.\n\nTrimmed slightly:\n\n```\n---\nname: meeting-notes-to-actions\ndescription: Use when the user has meeting notes, a call transcript, or a voice-memo dump and wants decisions, action items, and a follow-up email out of it.\n---\n\n# Meeting Notes → Actions\n\n## Step 1 — Load context\nRead `.solo/business.md` if present (tone, client names). Works standalone if missing.\n\n## Step 2 — Extract, then verify\n- Decisions — things agreed. Do not upgrade \"we could\" into \"we will\".\n- Actions — owner + due date if stated; otherwise `(no date set)`.\n- Open questions.\n- Flags — budget hesitation, scope drift, unclear decision-maker.\nShow decisions + actions and ask: \"Anything wrong or missing?\"\n\n## Step 3 — Write `meetings/<date>-<slug>.md`\n<decisions / actions table / open questions / flags / follow-up email under 150 words>\n\nIf it was a discovery call, add `## Proposal inputs` so /proposal-writer can use it directly.\n\n## Do not\n- Do not invent dates, owners, or commitments.\n- Do not include Flags in anything sent to the client.\n- Do not summarize the whole conversation.\n```\n\nPaste notes, confirm the decisions, thirty seconds later there's a file and a recap email short enough to get read.\n\nFive skills, MIT: `setup-business`, `meeting-notes-to-actions`, `invoice-generator`, `weekly-review`, `linkedin-post`.\n\nCopy `skills/` into `~/.claude/skills/`, run `/setup-business`, then try `/meeting-notes-to-actions` on your last call.\n\nThe full pack — 26 skills across the client lifecycle (lead research, cold outreach, discovery prep, proposals, pricing, SOW, kickoff, client updates, scope-creep guard, late-payment sequence, monthly finance summary, case studies, testimonials, a one-file portfolio site, inbox triage, SOPs, decision memos) plus a playbook on chaining and customizing them — is the thing the experiment is selling: **[Solo Stack on Gumroad](https://solostack91.gumroad.com/l/solo-stack)**, $19 during launch. Every sale goes in the public ledger; I'll publish the day-30 report, profit or loss.\n\nEither way, steal the pattern: one context file, files not chat, constraints not instructions.
