Changelog

1.1.0

New

• A brand without a kit: deck.py brand --colors "#F26B1D,#2B2B2B" --font Nunito builds a complete brand from colours and a font (or --display-font/--body-font). The brand.json format is now documented in step-1-source.md.
• On-brand chart colours, always: when a kit has fewer than six colours, the theme accents are shades and tints of the brand's own colours, never Office blue and orange.
• A readable brand colour for text: when the primary colour fails WCAG AA on the background (bright orange on white, say), brand reports it and writes --color-primary-text, a darker shade to use for text while shapes keep the true colour.
• Highlight a single bar: per-series point_colors ({"3": "#F26B1D"}), plus label_position and label_color for chart data labels. No more zero-value series workarounds.
• A quick path for small jobs: decks of 10 slides or fewer whose content the user supplied skip narrative.json and the long reading list. A pure correction in Edit mode (numbers, wording, chart data, same layout) gets a proportionate check instead of the full scored review.

Fixed

• The taste lint no longer flags the deliberate optical nudge of big numerals (which the design guide recommends), the inner padding of a chart's box, or a backing card in a stacked-deck motif as "margin" or "near-miss" majors. Real misalignments are still caught. The launch deck went from 4 false majors to 0.
• A canvas rebuild in Edit mode keeps the previous deck.pptx as deck-previous.pptx when the user has already shared it.

1.0.1

Fixed

• Mac and Linux without PowerPoint no longer report FAIL on a good deck. "PowerPoint not installed" isn't an error any more. When LibreOffice does the rendering, pixel diffs are warnings, and the report says the check is approximate. A real PowerPoint render still fails on a real diff.
• build and compile install the brand kit's fonts per-user when they aren't installed, so renderers stop substituting them. Each install is logged, deck.py uninstall --fonts removes them, and --no-font-install turns this off. QA now flags a font that exists only in the kit.
• Fonts in a CSS stack resolve the way a browser picks them: the first family installed on this machine. A deck with no brand kit on Mac or Linux no longer asks for Segoe UI. A missing core Office font (Arial, Calibri, Segoe UI…) is a warning, because recipients' PowerPoint has it.
• The demo deck ships its OFL fonts (Manrope, Inter), so it rebuilds on any OS.
• Demo deck slide 1: the top card of the Morph stack now shows a real cover slide instead of an empty card.

New

• Install on Gemini CLI (gemini-extension.json) and Cursor (.cursor-plugin/plugin.json).
• README demo GIF, plus measured time and token numbers.
• GitHub Discussions for questions and ideas.

1.0.0 — first public release

/deck is now Slidekick (/slidekick). Saying "/deck" still triggers it.

New

• PowerPoint for Mac QA (beta). On macOS, renders go through PowerPoint for Mac (AppleScript → PDF) instead of LibreOffice. Text baselines are calibrated and cached separately for Mac. Transitions and animations are checked in the XML only, because PDF export doesn't report them.
• deck.py uninstall [--fonts] removes the private environment and caches. With --fonts it also removes the fonts /slidekick installed.
• --author on compile, build and edit sets who the .pptx is attributed to.
• Install on Codex, opencode, Antigravity, Cursor and others: npx skills add, .codex-plugin/, and skill links under .agents/, .opencode/ and .claude/.
• Test suite and CI on Windows, macOS and Linux.

Fixed

• Decks no longer inherit a template's author (or python-pptx's default "last modified by"). Edited decks keep the original author.
• --trace works after the subcommand (deck.py build --trace).
• doctor reports a missing Playwright instead of crashing, and names the QA backend it will use.
• fonts fetch saves into the project's brand/fonts (it follows -p), not the current folder.
• Importing the calibration module no longer creates folders.
• The private environment is isolated from system packages. Dependency versions are capped at the next major release.
• Off Windows, generic CSS families map to fonts that exist on Mac and Windows, instead of Segoe.
• brand.json stores paths relative to brand/, so projects can be moved and shared without exposing your folders. A brand template given by a relative path is no longer dropped silently, and a missing template now warns.
• Chart edits keep the chart's number format ("$0.0M") instead of resetting the axis to General.
• Images whose object-position is in px and whose aspect matches their box no longer crash compile (NaN).
• fetch follows -p and saves into the project's assets/.

0.2.0 (as /deck)

• Edit mode: change an existing deck in place with an atomic edits.json (text, find/replace, charts, tables, images, styling, delete/move/duplicate/import slides). Formatting is preserved.
• Analyse mode: inspect any .pptx/.ppt/.odp/.pdf to get an outline, inventory, renders and issues.
• Design review: taste lint, plus a fresh-eyes reviewer gate (no blocker, every dimension ≥ 4/5).

0.1.0 (as /deck)

• Create mode: brief + brand kit → HTML canvas → native, editable .pptx, followed by PowerPoint-rendered QA with baseline calibration.
