Use to write or refresh TFactory blog posts. |

/blog
Help the user write and ship a post to the TFactory GitHub Pages blog. The
blog lives in this repo under docs/ (Jekyll), is themed Gruvbox to match the
portal, and serves at /blog/.
Inputs
- topic/title (arg or ask): what the post is about. If only a rough idea is
given, propose a sharp title + one-line subtitle and confirm before drafting.
--draft: write the file but do NOT commit/publish (default is to stop
before pushing and ask).
Where things live
| Thing | Path |
|---|
| Posts | docs/_posts/YYYY-MM-DD-<slug>.md |
| Post layout | docs/_layouts/post.html (auto-applied via _config.yml defaults) |
| Blog index | docs/blog.md → /blog/ (lists site.posts newest-first) |
| Permalink | /blog/:year/:month/:day/:title/ (set in docs/_config.yml) |
| Styling | docs/assets/css/tfactory.css (Gruvbox; .post-*, .prose) |
Never invent a date — get today's date from the environment/context and use
it for both the filename prefix and the date: field.
Post front matter (required shape)
---
layout: post
title: "A sharp, specific title — not clickbait"
subtitle: "One line that says what the reader gets. Renders under the title and as the blog-list excerpt."
date: YYYY-MM-DD
author: DataSeek Team
---
layout: post is auto-applied by _config.yml defaults, but include it anyway
for clarity. The filename must be docs/_posts/YYYY-MM-DD-<kebab-slug>.md
or Jekyll won't pick it up.
Voice & persona (match the product)
TFactory's positioning is "test quality, not test count" — engineering-
honest, anti-hype, terminal-native, for people who care about craft. Write like
that:
- Lead with the real problem, not a feature. Earn the reader.
- Concrete > abstract. Name the 5 signals, the lanes, the agents.
- No marketing fluff, no exclamation marks, no "revolutionary". Confident, plain.
- British-leaning, lowercase-y, developer-to-developer.
- Short paragraphs. One idea each.
Make it look good (structure for the Gruvbox theme)
The theme styles these well — use them:
Procedure (PARR — announce, run, verify, continue)
1. Settle the angle
Confirm title + subtitle + the one thing the reader should leave with. If the
user gave a vague topic, propose 2-3 title options and pick one with them.
2. Write the post
Create docs/_posts/<today>-<slug>.md with the front matter + body. Follow the
voice + structure above. Checkpoint: file exists; front matter parses;
filename date == date: field.
3. Preview it (the look)
The repo can't run Jekyll headless, so preview with the nix-Chrome harness used
for the demos:
CSS="$(pwd)/docs/assets/css/tfactory.css"
export CHROME_PATH="/etc/profiles/per-user/$USER/bin/google-chrome-stable"
node -e "const{chromium}=require('@playwright/test');(async()=>{const b=await chromium.launch({headless:true,executablePath:process.env.CHROME_PATH});const c=await b.newContext({viewport:{width:1280,height:1400}});const p=await c.newPage();await p.goto('file:///tmp/blog-prev.html',{waitUntil:'networkidle'});await p.waitForTimeout(1000);await p.screenshot({path:'/tmp/blog-prev.png',fullPage:true});await b.close();})()"
Show the screenshot to the user (SendUserFile). If it's installed, a real
cd docs && bundle exec jekyll build is the gold check, but the screenshot is
usually enough. Checkpoint: the post reads well + matches the Gruvbox brand.
4. Publish (only when the user says so)
Branching model: work on dev, then promote to main so Pages rebuilds.
git add docs/_posts/<file> && git commit -s -m "blog: <title>"
git push origin dev
git fetch origin -q && git merge-base --is-ancestor origin/main origin/dev \
&& git push origin dev:main
End the commit message with the repo's sign-off footer. Checkpoint: the
commit landed; dev == main; remind the user Pages takes a minute to rebuild.
Notes
- One post per file; don't edit an old post's
date:/filename to "bump" it.
- Keep posts in TFactory's lane (testing, QA, the pipeline, the moat) — this is
the product blog, not a personal one.
- The blog index, nav link, and styling already exist — a new post just needs
the
_posts/ file; it shows up automatically.
