1. ▌
   Change With Proof · codingcossack bundle

   Use when changing software whose existing behaviour matters — fixing bugs or regressions, refactoring, migrating schemas or APIs, changing auth, payments, webhooks, persistence, or user-visible behaviour, removing code, resuming inherited work — and when reviewing such changes or judging whether they are done. Every claim of fixed, compatible, unused, or done must carry evidence whose scope matches the claim. Do not use for pure explanation or Q&A, greenfield scaffolding with no existing behaviour at stake, prompt writing, dedicated security audits, or visual design and restyling work, however large.

   Geo SEO Toolkit · codingcossack bundle

   Use whenever search or AI-search visibility of a real site is at stake: diagnosing indexing, ranking, crawling, or citation problems; implementing or reviewing canonicals, redirects, robots and crawler policy, sitemaps, rendered HTML, structured data, or programmatic URL sets; launching, migrating, or retiring public pages or domains; and verifying that any such change is actually live and correct on the public surface. Covers Search Console and analytics diagnosis, JobPosting and other schema, local business and portfolio SEO, CDN/WAF/cache and AI-crawler access, and re-checking work previously declared fixed. Do not use for generic marketing copy, sales CRM, or outreach without a real site and evidence.

   Writing Claude 5 Prompts · codingcossack bundle

   Use when writing, rewriting, reviewing, shortening, or handing off prompts, system prompts, agent briefs, skills, CLAUDE.md files, or task specifications targeting Opus 5 or Fable 5 — including when a prompt was tuned for an older model, has grown repetitive or over-scaffolded, or is unclear about scope, autonomy, evidence, output length, or stopping. Not for prompts whose primary result is a visual artefact; writing-claude-design-prompts owns those.

   Writing Claude Design Prompts · codingcossack bundle

   Use when turning product notes, briefs, specifications, or mixed mission packs into prompts for Claude Opus, Fable, or another design-capable Claude model whose primary result is a visual artefact, frontend, redesign, prototype, design system, or image-to-code implementation.
