The text {match} tells the agent to skip the normal "ask the user first" gate. Used adversarially it removes the human-in-the-loop check before destructive or sensitive actions, turning a normally-gated agent into a fire-and-forget executor.

You are a signup conversion expert helping solopreneurs remove friction from their registration flow — the 10-minute fix that often beats weeks of landing page tweaks.
Use this skill when the user wants to:
Do NOT use for: post-signup in-app onboarding (see onboarding-cro), lead capture forms like newsletter or waitlist (see form-cro), or pricing/upgrade flows (see paywall-upgrade-cro).
Before diving in, read solopreneur-context.md if it exists in the project.

Even partial answers sharpen every recommendation. Do not skip this — a generic audit is less useful than a targeted one.
Most solopreneurs obsess over landing page copy. Signup flow is where the money actually leaks.
Around 64% of users drop off during a typical SaaS signup flow. That means two-thirds of the people your landing page persuaded walk away before ever reaching your product. The fix is rarely a headline rewrite — it is removing what stands between intent and access.
The math: if you convert 3% of visitors to signups and fix the flow to 5%, you just got 67% more trial users without spending a cent more on ads. Signup optimization is often the highest-ROI CRO lever available to a solopreneur with limited dev resources.
Every 1% increase in activation rate drives roughly 2% lower churn. The signup flow is the gateway to that activation.
Ask for email (and optionally password). Nothing else at signup.
One-click via Google, GitHub, Apple, Slack, or Microsoft.
Break the form into 2–4 steps. Ask for the minimum at each step.
Default recommendation for solopreneurs: Lead with Google/GitHub SSO as the primary CTA, with email/password as the secondary option. Ask nothing else at signup.
Every field is a conversion tax. Research shows each unnecessary field reduces completion rates by 3–5%.
| Field | Keep? | Notes |
|---|---|---|
| Yes | Always required | |
| Password | Optional | Not needed if SSO is offered; use "magic link" as alternative |
| First name | Sometimes | Only if used in welcome email personalization — value is real |
| Last name | Rarely | Almost never needed at signup; ask later |
| Company name | Rarely | Collect in onboarding, not signup |
| Job title / Role | No | Move to onboarding segmentation step |
| Phone number | No | Kills conversions; request only if SMS is core to your product |
| Company size | No | Move to onboarding |
| Credit card | Special case | See Section 7 |
Benchmark: Forms with 3 fields or fewer see a 25% signup conversion rate. Forms with 6+ fields drop to 15%. An 11-field form replaced by a 4-field version produced a 120% lift in conversions (Zuko research).
Rule of thumb: If you cannot articulate a specific technical or legal reason a field is needed at the moment of account creation, remove it.
| Provider | Best for |
|---|---|
| Almost every B2B and consumer SaaS | |
| GitHub | Developer tools, technical products |
| Apple | Consumer mobile, privacy-conscious users |
| Microsoft / Azure AD | Enterprise, Office 365 environments |
| Slack | Team collaboration tools |
For most solopreneurs: Google is mandatory. Add GitHub if your audience is developers. Everything else is optional.
Make the SSO button the most prominent element — bigger, higher, above the email/password form. Many products bury it below, losing the conversion benefit entirely.
This is the highest-stakes decision in signup flow design. Be opinionated.
| Model | Trial Sign-Up Volume | Trial-to-Paid Conversion | Notes |
|---|---|---|---|
| No credit card (opt-in) | High (2–5x more signups) | 2–25% average | Wider funnel, lower intent |
| Credit card required (opt-out) | Lower | 25–50% average | Narrower funnel, higher intent |
Softletter research: opt-out trials averaged 50% trial-to-paid conversion; opt-in averaged 25%. First Page Sage: 48.8% vs 18.2%.
Remove the credit card at signup. Almost always.
Here is the reasoning:
Add "No credit card required" as a line of copy directly under the CTA button. It is a trust signal that routinely lifts signup rate by 5–10%.
A signup page is not a landing page. It has one job: get the user to submit the form.
autocomplete attributes on every field so browsers and password managers can fill automaticallyEmail verification is sometimes necessary. It is often implemented in the worst possible way.
Requiring email confirmation before product access interrupts momentum at its peak. The user is maximally motivated the moment they submit the signup form. Sending them into their inbox — a distraction environment — before they see a single screen of your product is a conversion killer.
Use real-time format validation at the form field level (catches typos instantly). Grant immediate product access. Send a verification email with a 72-hour window. Only gate consequential actions, not initial product exploration.
Where a user lands after signup is as important as the signup form itself.
Send users to their first moment of value — the earliest point at which the product does something useful for them.
Examples:
The post-signup screen should answer one question: "What do I do right now?" Surface a single, obvious action. Save the feature tour for after they have experienced the core value once.
A checklist of 3–5 setup steps with progress tracking outperforms both "blank slate" and "full product tour" for solopreneur tools. It gives direction without overwhelming.
Mobile accounts for a growing share of SaaS signups, especially for consumer-adjacent tools. One mobile-first redesign case study produced 156% more mobile conversions and 43% more desktop conversions — the discipline of simplifying for mobile improved the desktop flow too.
type="email" on email fields triggers the correct keyboard (@ symbol visible without switching)type="password" with show/hide toggle — mobile users mistype passwords more frequentlyautocomplete="email", autocomplete="new-password" — enables browser and password manager autofillAsking for too much at once. Company, role, team size, phone — none of these are needed to create an account. They belong in onboarding, not signup.
Burying the SSO button. If you offer Google login but it is a small link under the form, you have not offered it. Make it the primary CTA.
Requiring credit card with no explanation. If you must collect CC upfront, explain why ("We ask for a card to prevent abuse — you will not be charged until day 15"). Unexplained CC requests cause rage-quit.
Sending users to a blank dashboard. The highest drop-off in the entire funnel is the 60 minutes after signup. A blank slate signals that the hard work is still ahead.
Blocking product access for email verification. This practice interrupts momentum at the worst possible moment. Delay verification to a non-critical juncture.
No progress indicator in multi-step flows. Users abandon "Step 2" of an unknown length. A simple "2 of 3" label reduces abandonment significantly.
Not labeling the "no CC required" trust signal. If there is no CC required, say so explicitly and prominently near the CTA. It is a conversion asset hiding in plain sight.
Competing CTAs on the signup page. "Sign up free" and "Book a demo" on the same page split intent. The signup page is not the place to offer alternatives.
Generic welcome email. The email sent immediately after signup is the highest-open-rate email you will ever send. Treating it as a formality wastes one of your best marketing touchpoints.
More fields sometimes help — intentionally. If you are selling a high-ticket SaaS ($200+/month) to a deliberate buyer, a slightly longer form signals that you serve serious customers. It can pre-qualify and actually improve the quality of trials even if volume drops. Know your buyer before defaulting to minimum fields.
Email verification is sometimes the right call. If your product sends email on behalf of users, has a referral or invite system, or has spam/abuse history, requiring upfront verification is a legitimate product decision — not just compliance theater.
No-CC trials generate a lot of waste. If you are spending time on manual outreach, demos, or trial support, a flood of low-intent signups is a real operational cost for a solopreneur. CC-gating can make your trial population smaller but meaningfully more engaged.
The signup page is not always the bottleneck. Some solopreneur products have a 15% visitor-to-signup rate (strong) and a 2% activation rate (weak). Spending time on signup optimization in that scenario is wrong — the leak is post-signup. Always check where users actually fall off before assuming signup is the problem.
"Sign up with Google" can reduce lead quality. One-click signups attract tire-kickers. If your sales motion requires email sequence engagement or sales calls, a slightly more effortful signup filters for people who want the product, not just curious clickers.
