| 1 | +# UI/UX Skills Deep Search |
| 2 | + |
| 3 | +Generated: 2026-06-24 |
| 4 | + |
| 5 | +Scope: local-first UI/UX skills, agents, and plugins for Codex that improve interface design without depending on hosted design services such as Figma, Canva, Stitch, or proprietary cloud design tools. |
| 6 | + |
| 7 | +## Outcome |
| 8 | + |
| 9 | +Confirmed installed winner: |
| 10 | + |
| 11 | +- Skill: `ui-ux-pro-max` |
| 12 | +- Installed path: `/home/michel/.codex/skills/ui-ux-pro-max/SKILL.md` |
| 13 | +- Provenance note: `/home/michel/.codex/skills/ui-ux-pro-max/CODEX_INSTALL.md` |
| 14 | +- Source: `https://github.com/nextlevelbuilder/ui-ux-pro-max-skill` |
| 15 | +- Source commit inspected: `1518fec29d19ce905cd0c689255137b9dcab7ccc` |
| 16 | +- License: MIT |
| 17 | + |
| 18 | +Decision: keep `ui-ux-pro-max` as the default installed UI/UX skill. It remains the best blend of adoption, breadth, local execution, and low friction for Codex. |
| 19 | + |
| 20 | +## Search Method |
| 21 | + |
| 22 | +I did a fresh live search and inspection instead of relying on the previous snapshot: |
| 23 | + |
| 24 | +- Web search for Codex UI/UX skills, `SKILL.md` packages, design plugins, and recent community recommendations. |
| 25 | +- GitHub REST API checks for adoption and maintenance signals. |
| 26 | +- Shallow local clones of the strongest candidates. |
| 27 | +- Local structure inspection for `SKILL.md`, plugin manifests, scripts, data, references, and licenses. |
| 28 | +- Lightweight validation where available. |
| 29 | +- Installed-copy verification from `/home/michel/.codex/skills/ui-ux-pro-max`. |
| 30 | + |
| 31 | +## Constraint |
| 32 | + |
| 33 | +Allowed: |
| 34 | + |
| 35 | +- Local `SKILL.md` packages. |
| 36 | +- Local scripts and CSV/JSON/reference data. |
| 37 | +- Local plugins or MCP servers when their core value works without hosted services. |
| 38 | +- Optional references to websites or docs. |
| 39 | + |
| 40 | +Excluded or downgraded: |
| 41 | + |
| 42 | +- Workflows whose main value requires Figma, Canva, Stitch, paid image APIs, cloud design workspaces, or proprietary hosted auth. |
| 43 | +- Heavy design platforms when the user asked for the best default skill rather than a full design studio. |
| 44 | +- Skills with broad triggers that would interrupt normal Codex frontend work too often. |
| 45 | + |
| 46 | +## Live Candidate Metrics |
| 47 | + |
| 48 | +Checked with the GitHub REST API on 2026-06-24. |

| 68 | + |
| 69 | +Inspected source commit: |
| 70 | + |
| 71 | +```text |
| 72 | +1518fec29d19ce905cd0c689255137b9dcab7ccc |
| 73 | +``` |
| 74 | + |
| 75 | +Observed contents: |
| 76 | + |
| 77 | +- `SKILL.md` source under `.claude/skills/ui-ux-pro-max/SKILL.md`. |
| 78 | +- Codex platform template under `cli/assets/templates/platforms/codex.json`. |
| 79 | +- Local scripts: `core.py`, `design_system.py`, `search.py`. |
| 80 | +- Local datasets: products, styles, colors, typography, charts, UX guidelines, landing patterns, app interfaces, React performance, and stack-specific guidance. |
| 81 | +- `skill.json` reports version `2.5.0` and Codex platform support. |
| 82 | +- README describes 67 UI styles, 161 palettes, 57 font pairings, 99 UX guidelines, 25 chart types, and 16 tech stacks. |
| 83 | + |
| 84 | +Installed-copy verification: |
| 85 | + |
| 86 | +- `data/` matches the inspected source copy. |
| 87 | +- `scripts/` matches the inspected source copy, ignoring generated `__pycache__`. |
| 88 | +- The installed script generated a real design-system recommendation for `SaaS analytics dashboard`. |
| 89 | +- The skill is copied into `~/.codex/skills`; it is not symlinked to the cloned repo. |
| 90 | + |
| 91 | +Why it wins: |
| 92 | + |
| 93 | +- It has the strongest public adoption signal by a large margin. |
| 94 | +- It is a single default skill, not a full app or multi-plugin suite. |
| 95 | +- It has local searchable design intelligence rather than only prose. |
| 96 | +- It covers both UI appearance and UX checks across common frontend stacks. |
| 97 | +- It is broad enough to help with landing pages, dashboards, SaaS/admin UI, mobile UI, charts, typography, colors, accessibility, and reviews. |
| 98 | + |

| 105 | +``` |
| 106 | + |
| 107 | +Observed contents: |
| 108 | + |
| 109 | +- Large local-first design platform, approximately 364 MB in the shallow clone. |
| 110 | +- 156 `skills/*/SKILL.md` files plus 109 `design-templates/*/SKILL.md` files. |
| 111 | +- Native desktop/web apps, daemon, MCP/platform packages, design systems, templates, export tooling, and agent integration docs. |
| 112 | +- README and website describe installation into Codex via Open Design tooling. |
| 113 | + |
| 114 | +Why it did not become the default skill: |
| 115 | + |
| 116 | +- It is the best full local design platform found, but the ask was for the best UI/UX skill. |
| 117 | +- Installing the whole platform would add a large design workspace and many optional services/skills. |
| 118 | +- The repository includes many skills whose best path depends on optional external services such as Figma, image/video providers, or web-connected workflows. |
| 119 | + |
| 120 | +Recommended later if the goal becomes a local design studio, artifact preview system, or MCP-backed design workspace. |
| 121 | + |
| 122 | +### `hallmark` |
| 123 | + |
| 124 | +Inspected source commit: |

| 126 | +```text |
| 127 | +aeb42fb354ff4efa36ab475773a082315a3af2ce |
| 128 | +``` |
| 129 | + |
| 130 | +Observed contents: |
| 131 | + |
| 132 | +- `skills/hallmark/SKILL.md` |
| 133 | +- 23 local reference files under `skills/hallmark/references/` |
| 134 | +- Worked examples and local site examples. |
| 135 | +- Strong focused mission: anti-generic, anti-AI-slop design. |
| 136 | +- Public adoption is now significant: 3,355 stars and 207 forks. |
| 137 | + |
| 138 | +Why it was not installed as the default: |
| 139 | + |
| 140 | +- It is an excellent complementary skill, but it is intentionally opinionated. |
| 141 | +- Its trigger covers new apps and landing pages broadly, and its default flow says it should always ask for design context before designing. |
| 142 | +- That could conflict with Codex's normal implementation flow when the user expects direct execution. |
| 143 | + |
| 144 | +Recommendation: install later as `hallmark` if the priority is maximum visual distinctiveness and anti-template redesign work. Do not make it the default broad UI/UX skill yet. |
| 145 | + |

| 152 | +``` |
| 153 | + |
| 154 | +Observed contents: |
| 155 | + |
| 156 | +- 96 `SKILL.md` files found. |
| 157 | +- Multiple Claude plugin manifests under `.claude-plugin/plugin.json`. |
| 158 | +- Covers research, strategy, systems, UI, interaction, prototyping/testing, design ops, toolkit, and visual critique. |
| 159 | +- Good ecosystem signal and external recommendations. |
| 160 | + |
| 161 | +Why it was not installed as the default: |
| 162 | + |
| 163 | +- It is a suite of design-process plugins, not one Codex-default UI/UX skill. |
| 164 | +- The plugin shape is Claude-first and would need deliberate conversion or plugin packaging for Codex. |
| 165 | +- It is stronger for design process and handoff than for a single low-friction frontend-quality default. |
| 166 | + |
| 167 | +### `designpowers` |
| 168 | + |
| 169 | +Inspected source commit: |
| 170 | + |

| 173 | +``` |
| 174 | + |
| 175 | +Observed contents: |
| 176 | + |
| 177 | +- 36 skills found under `skills/*/SKILL.md`. |
| 178 | +- Agent-team style design workflow. |
| 179 | +- Strong inclusive-design and design-process orientation. |
| 180 | + |
| 181 | +Why it was not installed as the default: |
| 182 | + |
| 183 | +- It is a design team/process system, not the simplest broad UI/UX enhancement skill. |
| 184 | +- It is useful when directing multiple design roles, but too much ceremony for routine Codex UI implementation. |
| 185 | + |
| 186 | +### `stark` |

| 188 | +Inspected source commit: |
| 189 | + |

| 193 | + |
| 194 | +Observed contents: |
| 195 | + |
| 196 | +- `.codex-plugin/plugin.json` |
| 197 | +- Root `SKILL.md` |
| 198 | +- 8 routed skills for UX, web, platform, cross-platform, and design tokens. |
| 199 | +- 71 local reference files in prior inspection; current clone contains rich references, commands, token assets, screenshots, and helper scripts. |
| 200 | +- Local tests passed: |
| 201 | + |
| 202 | +```text |
| 203 | +13 passed in 0.03s |
| 204 | +``` |
| 205 | + |
| 206 | +Why it was not installed as the default: |
| 207 | + |
| 208 | +- It is the best Codex-native plugin architecture found. |
| 209 | +- Adoption is still tiny compared with `ui-ux-pro-max`, Hallmark, Open Design, and Designer Skills. |
| 210 | +- It is better as a future plugin install when Codex-native routing matters more than public validation. |
| 211 | + |
| 212 | +## Final Ranking |
| 213 | + |
| 214 | +1. `ui-ux-pro-max` - best default UI/UX skill for Codex, installed. |
| 215 | +2. `open-design` - best full local design platform, not installed as a default skill. |
| 216 | +3. `hallmark` - best focused anti-generic visual-taste skill, install later if desired. |
| 217 | +4. `designer-skills` - best broad design-process suite, not Codex-native enough for default install. |
| 218 | +5. `stark` - best Codex-native UI/UX plugin architecture, low adoption but high quality. |
| 219 | +6. `frontend-design` - good lightweight aesthetic skill, already covered by existing installed design guidance and `ui-ux-pro-max`. |
| 220 | + |
| 221 | +## Installed State |

| 268 | +## Recommendation |
| 269 | + |
| 270 | +Keep `ui-ux-pro-max` installed as the default. It is the best current answer for a broadly useful, highly praised, local-first UI/UX Codex skill. |
| 271 | + |
| 272 | +If a second UI/UX install is desired later, choose based on need: |
| 273 | + |
| 274 | +- Install `hallmark` for high-craft anti-generic landing pages and redesigns. |
| 275 | +- Install `stark` for Codex-native UI/UX plugin routing. |
| 276 | +- Install `open-design` for a full local design workspace and MCP/platform workflow. |
| 277 | + |
| 278 | +Restart Codex if `ui-ux-pro-max` is not visible in the available skills list. |
