Skill Claude CodeCodex

Tasks: drafting or improving a cold DM, cold email, or intro message. Also use when someone asks how to reach strangers to find their first users. Not for warm…
Skill Claude CodeCodex
The strategy layer for building an audience — from zero followers to a growing, engaged following. Covers what to post and what not to post, writing social bios, selecting platforms, diagnosing why content isn't landing, creating content plans and themes, and getting unstuck creatively. Use for ongoing content…
Skill Claude CodeCodex
Use when someone has a specific piece of text to write, rewrite, or brainstorm — landing pages, cold emails, launch posts, investor updates, bios, tweets, product descriptions, ad copy, headlines, taglines, or subject lines. The user wants actual words drafted or edited, not strategy. Not for content strategy, brand…
Skill Claude CodeCodex
Use when someone has a specific decision to make and can't move forward — should I pivot, which opportunity to pursue, how to allocate limited time, whether to quit, take a deal, fire someone, or make a big bet. Also for prioritization paralysis when juggling competing demands. Not for general stuckness, growth…
Skill Claude CodeCodex
Use when someone needs help evaluating, planning, or improving the visual design and layout of a landing page, product UI, app screen, pitch deck, or social asset. Also use when someone is stuck on how to start designing (blank canvas paralysis, tool choice). Gives opinionated, prioritized feedback using the Useful >…
Skill Claude CodeCodex
Use when someone wants to test something, design an experiment, evaluate results from a test, or break through a growth plateau with rapid experimentation.

Skill Claude CodeCodex

Diagnoses the founder's actual stage, applies the marketing-vs-selling gate, runs AARRR funnel diagnostics to find where growth…
Skill Claude CodeCodex
Launch week coach — from pre-launch prep through post-launch recovery. Use when a founder is preparing to launch (needs a pre-launch checklist or readiness check), needs help with what to post and who to DM during launch week, or just launched to silence/disappointing results and needs a recovery plan. Applies the…
Skill Claude CodeCodex
Help a founder go from idea or unfinished project to a live MVP in one week. Applies the toy version question, scope-down exercises, and the useful→usable→beautiful hierarchy. Also use when someone just shipped and asks about distribution or launch strategy — redirects from marketing to selling with the pre-launch…
Skill Claude CodeCodex
Use when someone needs to craft or refine their core narrative — origin story, pitch, "why" statement, brand voice, or communicating a major change (pivot, shutdown, rebrand). This is the deeper work of finding and shaping the story that connects everything they do. Not copywriting (making words effective) and not…
Skill Claude CodeCodex
Diagnoses why someone is stuck when they can't name the root cause themselves. Pattern-matches their situation to one of six categories — local minimum, perfectionism paralysis, burnout, solo player trap, wrong audience, or emotional decision disguised as logical — and delivers the targeted framework with concrete…
Skill Claude CodeCodex
Use when someone needs to prepare for user conversations, make sense of what users told them (especially mixed or confusing feedback), or find people to talk to for customer discovery. Covers the full practice of learning from real conversations — what to ask, how to interpret feedback, and where to find willing…
Skill Claude CodeCodex
Plan and conceptualize a single video — a launch video, product demo, founder journey, or first video ever. Use when someone wants to make a video but does not know where to start, needs help structuring a specific video (shot list, emotional arc, music selection), or is discouraged after a video flopped and wants to…
Skill Claude CodeCodex

Seven sequential steps, each grounded in a named framework from buildspace lectures. Walk through the full ritual every week — no skipping, no shortcuts. Builds judgment over time through deliberate…
