Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00146 | $0.03235 |
| Opus 5.5 | $0.00058 | $0.01294 |
| Sonnet 5.5 | $0.00029 | $0.00647 |
| Haiku 4.5 | $0.00015 | $0.00324 |
Grade A, and why
redesign-codex-ui scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 205 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Redesign Codex UI
Transform the current Codex interface into a coherent, production-ready design. Treat reference images, personas, and style labels as design evidence—not as permission to replace working product behavior with a static mock.
Choose the input path
Accept any combination of:
- Reference image: inspect composition, density, hierarchy, color, type, radius, elevation, icon treatment, and interaction cues.
- Role or persona: translate the role into workflows, information priority, terminology, density, defaults, and accessibility needs.
- Personal, idol, or character theme: build a coherent edition around user-supplied portraits, signatures, memorabilia, original characters, or licensed IP assets. Theme navigation, hero, capability cards, composer, profile, and microcopy—not only the palette.
- Named style: translate adjectives, products, eras, brands, or designers into explicit visual rules. Recreate principles, not protected logos, illustrations, or pixel-identical branded assets.
- Open brief: infer a suitable direction from the existing product and state assumptions before implementation.
Apply this precedence when inputs conflict:
- Explicit functional and accessibility requirements
- Explicit user corrections and exclusions
- Reference image structure and visual evidence
- Persona workflow needs
- Named style cues
- Existing interface conventions
Read references/input-translation.md when the request includes a reference image, persona, or named style. Do not ask for information that can be inferred safely from the repository or supplied image.
Read references/personal-theme-packages.md when the request resembles a fan edition, celebrity skin, character theme, collectible interface, scrapbook interface, or deeply personalized Codex. Treat supplied identity assets as content with provenance and permissions, not as generic decoration.
Use assets/theme-library/default-identity.json and the transparent assets/default-identity/opcspace-ip-avatar.png as the default identity when the user supplies no IP image. Treat it as the OPCspace starter identity, not as a mandatory brand lock. If the user supplies another image, create a separate replacement profile with scripts/create_identity_profile.py; never overwrite the bundled default asset.
What ships with it
39 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
