Prompt engineering and iterative prompt versioning

Manuela Barcenas breaks down how marketing work has flipped from “writer + editor” to “manager of agents.” She shares two concrete workflows: (1) using Claude Projects to reposition and modernize 100 legacy blog posts in a week (including updated product messaging, AI-forward advice, and internal links), and (2) using Fellow’s “Ask Fellow” to mine anonymized customer-call transcripts for original quotes and pain points—then turning those insights into publish-ready integration/use-case articles in hours, not weeks. The throughline: output is easy now; taste, judgment, and review are the differentiators.

Timestamps

0:00–0:00 - Intro

1:18–2:54 Early Fellow days: one blog/week, months-long ebooks, craftsmanship vs scale

3:06–3:26 Scale expectations now: Amazon’s ebook upload limit anecdote (3/day)

3:40–4:30 Fellow previously managing an “army of writers” → now mostly AI/agents

4:36–5:00 “Taste” as the differentiator: what good content is + standing out

5:53–7:12 The 100-post update explained: not link swaps—full repositioning + modernized advice

7:25–9:36 Switching from ChatGPT to Claude; LinkedIn poll results + “context retention” theme

9:48–10:21 Claude Projects setup: separate projects to maintain context and instructions

14:43–15:29 Prompt versioning: internal links, new features, and repeated refinement cycles

18:55–19:20 Demo: paste URL → Claude fetches page → follows checklist automatically

19:26–20:24 Manuela’s QA: she reads/edits everything; “taste” = final layer (like editing writers)

21:38–23:17 Claude Skills discussion: turning repeated workflows into reusable MD “skills” (personal vs company-wide)

25:42–26:26 SEO myth: focus isn’t “AI penalty,” it’s originality and substance (quotes, stats, real insight)

26:38–28:39 Original content engine: Ask Fellow pulls anonymized customer-call insights by feature/integration

28:39–31:21 Building documents from transcripts (pain points, best practices, FAQs, quotes) → export to Doc/PDF

31:21–33:29 Feed exported insights into Claude Project to draft a tight article rich with customer quotes

33:29–36:06 Why it works: management loop (outcomes → constraints → review → feedback) at faster cadence

36:18–37:30 What’s next: Claude Code / Claude “co-work”; projects as “mini employees”

37:02–38:06 Personal brand workflow: Claude analyzes best LinkedIn posts → style guide + voice-based drafting (Whisper Flow)

38:28–39:12 Wrap: AI speed is real; staying current requires constant learning
