Use this skill when the user wants to:
Application form answers should be direct and specific — not a cover letter crammed into a text box. Each field has a purpose. Answer that purpose clearly, then stop.
The answer should feel like: A real person typed it, not a template was filled in.
Always read:
If the user hasn't provided a CV or JD, ask for them before writing.
Examples:
Format:
[Technology/skill] — [X years]. [One sentence on what you used it for, with a
specific project or context]. [Optional: secondary tools in the same category].
Rules:
Examples:
Format:
[Specific thing about the company/role that's genuinely interesting — not generic].
[How that connects to something the candidate has actually worked on].
[Optional: one line on why this domain, not just this company].
Rules:
Examples:
Format: List projects with one-line descriptions and links. Lead with the most relevant.
[Project Name] ([live URL] | [github URL]) — [one line: what it is and one
proof point]. [Stack if relevant].
Rules:
Examples:
Format: For open-text fields:
[Primary skill] — [X years]. [Specific use: what you built with it, in what context].
[Secondary skill] — [X years]. [Same].
[Note any relevant gaps honestly].
For rating/dropdown fields: pick the honest level — don't optimize for the highest rating if it's not accurate.
Rules:
Examples:
Format:
Current role + what you do there (1 sentence).
Relevant prior experience, briefly (1 sentence).
What you're looking for / why this role (1-2 sentences — specific to the company).
Optional: one project or side work that's relevant (1 sentence).
Rules:
Examples:
Format: Condensed STAR (no labels, just flow)
[Context in one sentence]. [What you specifically did — 2 sentences]. [Outcome
with a metric if possible — 1 sentence].
Rules:
Examples:
Format: Answer with a genuine opinion. Pick one or two things and explain the reasoning briefly.
Rules:
Always wrap the answer in a plain code block so it's clean to copy-paste:
[Answer text here]
If providing multiple answers (one per field), use separate code blocks with a label above each:
Years of React experience:
4 years. Used it across Screenr (agentic hiring SaaS), a Tauri-based POS
system, and several client projects. Also used Next.js where SSR was needed.
Describe your backend experience:
...
| Field type | Target length |
|---|---|
| Single-line text | 1 sentence |
| Short answer | 2-4 sentences |
| Long answer / textarea | 100-250 words |
| "Describe your experience" | 150-300 words |
| "Tell us about yourself" | 100-200 words |
| Portfolio / links section | List format, no prose |
When in doubt, shorter is better. Recruiters skim form answers. The goal is to be clear and memorable, not comprehensive.
Repeating the JD: ❌ "I am interested in this role because you are looking for someone to build scalable backend systems..." ✅ "What caught my attention was the real-time constraint — healthcare data at milliseconds latency is a different class of problem than most backend work."
Generic trait claims: ❌ "I am a fast learner who thrives in collaborative environments" ✅ [Just describe the actual work — the traits come through]
Over-qualifying: ❌ "While I may not have exactly 5 years, I believe my experience..." ✅ "The role mentions 5 years — I'm at 3, but the systems I've shipped are production-facing."
Listing without context: ❌ "React, Vue, Angular, Next.js, TypeScript, Node.js..." ✅ "React is my primary frontend framework — 4 years across Screenr and several client projects. Vue and Angular for about 3 years each, mostly dashboards and admin tooling."
Padding to fill space: ❌ Adding projects or experience that aren't relevant just to look prolific ✅ Include only what's relevant to this specific role

When the user wants to plan, design, or implement an A/B test or experiment, or build a growth experimentation program. Also use when the user mentions "A/B test," "split test," "experiment," "test this change," "variant copy," "multivariate test," "hypothesis," "should I test this," "which version is better," "test two versions," "statistical significance," "how long should I run this test," "growth experiments," "experiment velocity," "experiment backlog," "ICE score," "experimentation program," or "experiment playbook." Use this whenever someone is comparing two approaches and wants to measure which performs better, or when they want to build a systematic experimentation practice. For tracking implementation, see analytics. For page-level conversion optimization, see cro.

When the user wants to generate, iterate, or scale ad creative — headlines, descriptions, primary text, or full ad variations — for any paid advertising platform. Also use when the user mentions 'ad copy variations,' 'ad creative,' 'generate headlines,' 'RSA headlines,' 'bulk ad copy,' 'ad iterations,' 'creative testing,' 'ad performance optimization,' 'write me some ads,' 'Facebook ad copy,' 'Google ad headlines,' 'LinkedIn ad text,' or 'I need more ad variations.' Use this whenever someone needs to produce ad copy at scale or iterate on existing ads. For campaign strategy and targeting, see ads. For landing page copy, see copywriting.
