File a structured bug report during the Fern marketing site testing session. Use this whenever a tester says "I found a bug", "file a bug", "report this issue", "log a defect", or runs /file-bug. Walks the tester through capturing repro steps, expected vs. observed behavior, optional screenshot, then writes a JSON report under `testing/bugs/<tester>/<slug>.json`, copies the screenshot into `testing/screenshots/<tester>/<slug>.png`, commits, and pushes.

Scaffold a paid acquisition campaign for a Fern landing page under `campaigns/<slug>/`. Use whenever the user says "create a campaign for X", "launch a campaign on /lp/X", "spin up paid ads for X", or "/launch-campaign". Mirrors the leave-stainless / agent-ready / fern-vs-speakeasy structure with brief, LinkedIn + Google copy, creative briefs in the Hiroshi Yoshida house style, results scaffolding, and a prefix entry in `campaigns/README.md`. Stops short of committing.

Edit and improve SEO blog posts. Use this skill ONLY when the user says "SEO blog post" / "SEO blog", or asks to edit or review an SEO post. Do NOT trigger for general blog editing, Fern marketing blog posts, or other writing tasks. Typical triggers: "edit this SEO post", "review this SEO blog", "edit this SEO blog post".

Write a new SEO blog post from the top idea in the SEO ideas queue (seo/ideas.mdx). Use this skill ONLY when the user wants to write an SEO blog post, e.g. "write an SEO blog post", "write the next SEO post", "draft the next SEO blog", "draft an SEO post", or "/seo-blog-writer". This skill WRITES the first draft; the separate seo-blog-editor skill edits it afterward. Do NOT trigger for general blog writing, Fern marketing blog posts (use write-post), case studies, or other writing tasks.

Write customer case studies for Fern (a Postman company). Use this skill when the user asks to draft, write, or edit a case study, customer story, or customer success story for Fern. Triggers include: "case study", "customer story", "write up this customer", "draft a case study from these notes", or any request to turn interview notes or customer data into a structured case study. Also use when the user provides raw interview notes and asks to turn them into a publishable piece. Do NOT use for blog posts, changelog entries, LinkedIn posts, or general marketing copy.

Write employee profile blog posts for Fern (a Postman company), specifically with a "customer to employee/contributor" framing. Use this skill when the user asks to draft, write, or edit an employee profile, team profile, team spotlight, or "meet the team" post for Fern's blog. Triggers include: "employee profile", "team profile", "write up this person", "draft a profile from these notes", "customer to employee", "customer turned engineer", or any request to turn interview notes about a Fern team member into a publishable blog post. Also use when the user provides raw interview transcripts or meeting notes about a Fern employee and asks to turn them into a blog post or profile. Do NOT use for case studies, changelog entries, LinkedIn posts, or general marketing copy.

Draft a new Fern blog post. Use whenever the user says "write a post", "draft a blog post", "/write-post", "new blog about X", or asks for a blog-length piece for buildwithfern.com. Produces an MDX file under content/blog/<slug>.mdx with valid frontmatter, applies the Fern marketing voice from AGENTS.md by default, and stops short of committing. Only applies Kapil's voice when explicitly requested.

Author and edit Fern documentation: MDX pages, navigation, docs.yml config, custom components, landing pages, and changelog entries. Use when working in a Fern docs repo (a fern/ directory with docs.yml). Routes to a detailed reference per task.
