Author and apply a color theme for the running session with the set_theme tool, persisting it to ~/.pollytool/themes only after the user confirms. Use when the user asks to change polly's colors, match their terminal palette, fix a role that is unreadable, or save a theme for later.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Theme Restyle the running session by setting colors for polly's fixed role vocabulary, then persist the theme to a file only after the user agrees. ## 1. Interview first Do not guess. One topic per message: - **Background**: light or dark, and should the theme set its own `background` or sit on the terminal's? A theme is one look; a user who wants both a light and a dark version gets two themes with two names. - **Match the terminal or pin RGB**: reuse the terminal's own palette slots (`palette:N`) and color names, or specify exact colors (`#rrggbb`)? - **What to change**: only the roles the user complains about, or a full restyle? Every role you leave out keeps polly's built-in color. ## 2. Pick from the 25 roles - **Semantic (7)**: `ok`, `err`, `run`, `accent`, `active`, `muted`, `code`. - **Token (7)**: `syn-comment`, `syn-keyword`, `syn-string`, `syn-number`, `syn-func`, `syn-add`, `syn-del`. Omit a token role to inherit its fallback — `syn-comment`→`muted`, `syn-keyword`→`accent`, `syn-string`→`ok`, `syn-number`→`active`, `syn-func`→`code` (keeping its bold), `syn-add`→`ok`, `syn-del`→`err`. For code and diffs, usually set only the …

How to install
mdr add alexschlessinger/polly/theme-designer@sha256:28a08e54a3622dd4The line at the top of this page pins the label git:20260918.ef81e6a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
