add-theme

add-theme is a skill for Claude Code, Codex from IvanWng97/pixtuoid. It costs 84 tokens per session (850 once invoked), scanned A, original, MIT.

A checklist for adding a complete color theme to pixtuoid, a Rust application with a themed office display.

In plain words
What is it for?
Use it to create the theme file, fill its color roles, register its name, check the site manifest bridge, and regenerate committed media.
Why use it?
It prevents incomplete theme registration and missing color definitions that can make parts of the display use the wrong palette.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

add-theme 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 5d 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 — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.

add-theme (v1)

A theme is a pub static Theme with ~90 color roles across 9 groups (surface, office, lighting, furniture, effects, ui, tool_glow, ApplianceColors for corridor appliances, and SourceColors for per-CLI dashboard badge hues). Every field must be supplied — corridor appliances render wrong until each theme provides its own set.

When to use

  • "Add a <name> theme" / "new color scheme" / "port <palette>".

The checklist

Full current steps: .github/prompts/add-theme.prompt.md

  1. Create crates/pixtuoid-scene/src/theme/<name>.rs — fill EVERY field; never fall back to the normal palette.
  2. Register: mod in theme/mod.rs, append &<NAME> to ALL_THEMES, theme_by_name() resolves the kebab-case name.
  3. Theme roles MAY share an RGB (every bundled theme does) — the unique-RGB rule belongs to SPRITE PACKS (RECOLOR_KEYS B/H/S/P, enforced at pack load by validate_recolor_palette), not to themes. What binds a theme author are the per-theme legibility guards in theme/mod.rs: appliance_palette_is_legible_for_every_theme, source_badges_legible_for_every_theme, token_paper_is_legible_on_the_desk_for_every_theme, and sun_and_moon_read_warm_and_cool_for_every_theme.

The two steps agents miss (both have teeth)

  • site/src/themes.json row (id = the kebab-case name) — theme_gallery_manifest_matches_all_themes (theme/mod.rs) asserts the manifest ids == ALL_THEMES names, so the theme fails just test until the row exists. The site never runs the binary, so this bridge test is the only guard that the switcher stays in sync.
  • just gen-mediathemes.json drives the committed theme stills; a new theme drifts them, so regenerate and commit them or the smoke gen-check reds the PR (the same error the bridge test's message points at).

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.
