Operator-voice how-to guides and honest takes. Every post calls out where you're wasting Claude usage, time, or budget. Paired with what to do instead. No fluff, no listicles, no "10x your output." If a tactic doesn't earn its place, I cut it.
The complete guide: what Skills are, why they matter, where they live, how to build one, and the Skills worth setting up by discipline. The pillar for the whole cluster.
Which Skills an SEO marketer should build: SERP-brief, keyword clustering, on-page audit, internal linking. Each with a refuse-condition that stops Claude inventing search volume.
Skills for sequence drafting, subject-line variants, segmentation logic, and voice across a flow. With refuse-conditions against fabricated urgency and fake testimonials.
Skills for platform-native repurposing, hook generation, comment-reply triage, and per-platform tone. Refuses engagement-bait and fabricated stats.
Skills for brief-to-draft, content repurposing, editorial standards, and brand voice. Refuses to pad word count or invent statistics.
Skills for ad-copy variants, audience angles, ad-to-landing message match, and a claims-guard that refuses fabricated performance claims and fake urgency.
Skills for brand voice, a refusal-rules Skill that bans slop words, headline variants, and do/don't enforcement. The refuse-condition is the whole game.
The single most useful Skill a marketer can build. Example-based voice extraction, the SKILL.md structure, and how it loads automatically across every conversation and Project.
Skills for teardown structure, refuse-thin-data, positioning hypotheses, and account-level intel. The difference between confident output and confident bullshit.
Skills for performance readouts (one decision sentence, three findings), refusing trends from two data points, metric definitions, and readout format.
