Distillation

Date: Jul 21, 2026

• 🟡 (13:01) Tool result: pnpm install completed — dependency versions bumped: @astrojs/mdx 5.0.6→7.0.3, @astrojs/rss 4.0.18→4.0.19, astro 6.4.8→7.1.3; esbuild transitively bumped to 0.28.1 (clears prior advisory); "Ignored build scripts: esbuild@0.28.1" warning noted as non-blocking.
• 🟡 (13:01) Todo list updated: items 1 "Review Astro 6->7 migration guide" and 2 "Bump astro/@astrojs/mdx/@astrojs/rss versions" and 3 "Update lockfile and check peer deps (esbuild >=0.28.1)" all marked completed; item 4 "Fix any breaking-change code issues surfaced by the build" marked in_progress; item 5 "Run build and verify output (pages, RSS, OG tags, canonical)" pending; item 6 "Commit and push; confirm Dependabot alerts clear" pending.
• 🟡 (13:02) Tool result: pnpm build succeeded on Astro 7 — 17 pages built in 4.20s, 30 images optimized (cache reused), standard-site.json and index.html generated, no compiler errors.
• 🟡 (13:02) Assistant confirmed build passed clean on Astro 7 (17 pages, RSS and standard-site.json container-rendering still works) and proceeded to verify OG tags, canonical URLs, word-count remark plugin output, RSS content, and possible compressHTML: 'jsx' whitespace regression.
• 🟡 (13:02) Tool result: OG/canonical check on post ultimate-setup-labs — canonical https://byk.im/posts/ultimate-setup-labs/, og:title "My ultimate setup: a £40 box that codes while I poop", og:url matches canonical, og:image https://byk.im/_astro/ultimate-setup-labs.DxoFZ7ad.png — all intact. Word count text ("words"/"minutes") not found in rendered HTML. RSS confirmed 10 items with content, including titles "Read at BYK's", "My ultimate setup: a £40 box that codes while I poop", "Teaching my agent to wait".
• 🟡 (13:02) Assistant flagged two issues from build verification: (1) word-count regex returned no match — suspected compressHTML: 'jsx' whitespace change; (2) RSS output includes draft/uncommitted post "Teaching my agent to wait" — noted as pre-existing build-from-working-tree behavior, not caused by the Astro 7 upgrade.
• 🟡 (13:02) Tool result: raw HTML context around "minutes" showed ~ minutes ( words) — the numeric word/minute values are missing from the rendered ReadingInfo component output, confirming a real regression (not a whitespace-only compressHTML issue since numbers, not spaces, are missing).
• 🟡 (13:03) Investigation into word-count regression: Post.astro:12 does const { remarkPluginFrontmatter } = await render(postData); Post.astro:46 uses <ReadingInfo words={remarkPluginFrontmatter.words} />; ReadingInfo.astro:2 destructures words from Astro.props, line 3 computes readingTimeMinutes = Math.ceil(words / 200), line 4 pluralizes "minute"/"minutes", line 10 renders ~{readingTimeMinutes} {minutesText} ({words} words); same pattern in src/pages/posts/[slug].astro:24 and :38. Conclusion: remarkPluginFrontmatter.words is undefined, causing NaN/empty render.
• 🟡 (13:03) Tool result: @astrojs/mdx@7.0.3 deps confirmed via npm registry: @mdx-js/mdx ^3.1.1, acorn ^8.16.0, es-module-lexer ^2.0.0, estree-util-visit ^2.0.0, hast-util-to-html ^9.0.5, piccolore ^0.1.3, rehype-raw ^7.0.0, remark-gfm ^4.0.1, remark-smartypants ^3.0.2, source-map ^0.7.6, unist-util-visit ^5.1.0, vfile ^6.0.3, @astrojs/internal-helpers 0.10.1, @astrojs/markdown-remark 7.2.1 — confirms remark pipeline still bundled.
• 🟡 (13:03) Tool result: Astro docs "Add reading time" recipe (docs.astro.build/en/recipes/reading-time/) fetched — recommends installing reading-time, mdast-util-to-string, @astrojs/markdown-remark; documented v7 config pattern wires the remark plugin via top-level markdown.processor using unified({ remarkPlugins: [...] }) imported from @astrojs/markdown-remark, not via mdx({ remarkPlugins }); confirms remarkPluginFrontmatter is still read via await render(entry) in content-collection pages, or via Astro.props.frontmatter in plain layouts — the data.astro.frontmatter.X injection mechanism itself is still valid in v7.
• 🟡 (13:03) Assistant reasoning: recipe confirms data.astro.frontmatter.X pattern and remarkPluginFrontmatter access are still correct in v7, so the injection mechanism is intact — root cause must be in how/whether the plugin executes, not in the read side.
• 🟡 (13:04) Tool result: live (deployed) v6 site confirmed showing ~10 minutes (1859 words) for a post; new v7 dist build has 47 occurrences of empty ~ minutes ( across all built posts — confirms the word-count regression affects every post, not just one.
• 🟡 (13:04) Debugging: assistant backed up astro.config.mjs, added a temporary WORDCOUNT_DEBUG console.log inside the inline remark plugin factory in the mdx() config, rebuilt — no debug output appeared at all. Root cause identified: the wordCount remark plugin is not being invoked at all under Astro 7 / MDX 7 with the current config shape (not merely failing to set the value).
• 🟡 (13:05) Assistant reverted the debug line. Current astro.config.mjs content confirmed: imports defineConfig, tailwindcss (@tailwindcss/vite), mdx (@astrojs/mdx), icon (astro-icon), wordCount (./src/utils/word-count.mjs); integrations: mdx({ remarkPlugins: [() => (tree, { data }) => { const words = wordCount(tree); data.astro.frontmatter.words = words; }] }), icon(); site: "https://byk.im"; build.assetsPrefix: "https://byk.im/"; vite.plugins: [tailwindcss()].
• 🟡 (13:05) Tool result: grep of node_modules/@astrojs/mdx/dist/index.js, plugins.js, rehype-apply-frontmatter-export.js — key lines: extendMarkdownConfig defaults to true; isUnifiedProcessor(processor) branch copies remarkPlugins/rehypePlugins/remarkRehype/gfm/smartypants from config.markdown.processor; isSatteriProcessor(processor) branch (Sätteri, the new v7 default) only copies gfm/smartypants from processor.options.features — NOT remarkPlugins/rehypePlugins; warnDeprecatedMdxPluginOptions warns when remarkPlugins, rehypePlugins, or remarkRehype are passed directly as mdx() integration options (deprecated in v7).
• 🟡 (13:05) Tool result: full listing of node_modules/@astrojs/mdx/dist/index.js lines 40-114 confirming the above branch logic verbatim, including defaultMdxOptions = { extendMarkdownConfig: true } and the warnDeprecatedMdxPluginOptions deprecation-check function (checks for remarkPlugins, rehypePlugins, remarkRehype keys).
• 🟡 (13:05) Assistant root-cause conclusion (in progress): (1) passing remarkPlugins directly to the mdx() integration is now deprecated in @astrojs/mdx 7; (2) since Astro 7's default markdown processor is Sätteri (not unified), the isSatteriProcessor code path in @astrojs/mdx does NOT forward remarkPlugins/rehypePlugins from config.markdown.processor, unlike the isUnifiedProcessor path — explaining why the wordCount plugin never executes. Planned fix: migrate to the documented v7 approach — configure the wordCount remark plugin via a top-level markdown: { processor: unified({ remarkPlugins: [...] }) } config (imported from @astrojs/markdown-remark) rather than via mdx({ remarkPlugins }), to restore data.astro.frontmatter population.
