pixtuoid: Skill for Claude Code

.claude/skills/add-theme/SKILL.md

add-theme is a skill for Claude Code from IvanWng97/pixtuoid. It costs 80 tokens per session (486 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 19d 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.

What it actually says

add-theme

  1. Read the Theme struct in crates/pixtuoid-scene/src/theme/mod.rs and an existing theme (e.g. theme/dracula.rs) for the full field set.
  2. Create crates/pixtuoid-scene/src/theme/<name>.rs defining pub static <NAME>: Theme = Theme { ... }.
  3. Register it: add the mod in theme/mod.rs and append &<NAME> to the ALL_THEMES slice; its name field is the kebab-case --theme id.
  4. Add a row to site/src/themes.json (id = the kebab-case name, plus its presentation fields). theme_gallery_manifest_matches_all_themes asserts the manifest ids == ALL_THEMES names — the site never runs the binary, so this bridge test is the only guard that its theme switcher stays in sync. The theme stills need no commit in this PR: the site's render in CI, the README's in media-regen.yml from main (just gen-media renders them locally to look).
  5. Theme roles may share an RGB (every bundled theme does). What binds you are the *_for_every_theme legibility guards in theme/mod.rs.
  6. Run just test; update insta snapshots if the theme list changed.
  7. Visually verify with the beautify-decoration skill's snapshot loop — a palette that passes the legibility guards can still read badly.
  8. The local-review skill (CI runs the rest) — the regenerated stills fire REVIEW.md's local "Generated art / clips" row.
Changes

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.
