Inherit Legacy Style

affaan-m/ecc
1.4k installs240.8k stars
Summary

This one's for when you're onboarding Claude to a hand-written legacy codebase and don't want it rewriting everything in its own preferred style. It scans your project across four meta-architecture dimensions (file anatomy, state handling, infrastructure placement, error patterns), figures out what's consensus versus what's noise, then grills you one question at a time on real conflicts it found. The output is a `.ai-style-rules.md` with golden file examples and concrete DONTs that gets referenced in your CLAUDE.md so every subsequent code task opens with a compliance check. It's language-agnostic and works incrementally via Git diffs. Use it when style drift is a bigger risk than the hour you'll spend teaching the model your project's actual conventions.

go-code-review

cxuu/golang-skills

Use when reviewing Go code or checking code against community style standards. Also use proactively before submitting a Go PR or when reviewing any Go code changes, even if the user doesn't explicitly request a style review. Does not cover language-specific syntax — delegates to specialized skills.

data-quality-checker

tradermonty/claude-trading-skills

Validate data quality in market analysis documents and blog articles before publication. Use when checking for price scale inconsistencies (ETF vs futures), instrument notation errors, date/day-of-week mismatches, allocation total errors, and unit mismatches. Supports English and Japanese content. Advisory mode -- flags issues as warnings for human review, not as blockers.

design-review

jezweb/claude-skills

Review a web app or page for visual design quality — layout, typography, spacing, colour, hierarchy, consistency, interaction patterns, and responsive behaviour. Not a UX audit (that checks usability) — this checks whether it looks professional and polished. Produces a design findings report with screenshots. Triggers: 'design review', 'does this look good', 'review the design', 'check the layout', 'is this polished', 'visual review', 'design audit', 'make it look better', 'it looks off'.
