Write Blog

Write a blog post

You are helping a contributor write a blog post for the project's website. The bar: it reads like a person wrote it, it ranks for a search cluster no other post already owns, and it ships wired correctly into the site with the build green.

This skill exists so every contributor writes in the same voice, picks non-overlapping topics, and passes the same anti-AI-slop gate, whether or not they already know the house rules.

The one rule that gets a post rejected

No em dashes (—) or en dashes (–). Ever. The house voice bans them. Use a period, a comma, or "so"/"because"/parentheses instead. A single dash in a draft is a hard fail. There is a scanner: run bash check.sh (in this skill's folder) on any draft before you call it done.

Workflow

Do these in order. Don't skip the angle check or the humanizer pass.

1. Read the ground truth first

Before writing a word, read what already exists so you match voice and don't cannibalize keywords:

• Your site's post registry / index. Whatever lists every published post (a registry

file, a content collection, a CMS list, or the frontmatter across your blog's source directory). This is the live record of every published post and the angle it owns. Read every slug, title, description, and tag set.

• One or two full published posts (the prose sources) to absorb the voice.
• reference/angles.md (in this skill folder) for how to pick an angle that doesn't

collide, plus the topics still untapped.

• reference/voice.md for the house voice and the anti-AI checklist, self-contained.
• reference/craft.md for the writing craft: leads that win the click, spine structure,

and which creative-writing skill to reach for at each stage.

• reference/seo.md for on-page keyword placement, internal linking, verifying the

machine-readable SEO, and the post-ship distribution loop that earns the first backlinks.

2. Pick and pitch the angle

Every post must own a distinct search cluster. Two posts fighting for the same keywords cannibalize each other. From your post index and reference/angles.md, pick an angle no shipped post already owns, then pitch it back to the contributor in one line before drafting: the working title, the one-sentence thesis, and the 3-5 keyword phrases it targets. Confirm before you write the body. If they gave you a topic that collides with an existing post, say so and propose the adjacent-but-distinct angle instead.

3. Outline

A good post has a spine, not a listicle. Read reference/craft.md before you outline; the lead and the H2-spine are 80% of whether the post gets finished and ranked. Structure:

• A lead (description + opening) that names a concrete, specific problem the reader has.

Not "AI agents are transforming collaboration." Something like "Two agents can talk about a change all day. Handing over the change itself, byte for byte, is a different problem."

• 4-7 sections, each with a claim and **real code, real commands, or a real number from

your project** backing it. Read the actual source and docs of your project and quote it accurately. Made-up APIs are worse than no code.

• A "what this is NOT" or honest-limitations beat. The voice is a little contrarian and

admits what's deferred. That honesty is what makes it not read like marketing.

• A close that lands the thesis without a generic "in conclusion, the future is bright"

wrap-up. End on a concrete thing the reader can do or check.

4. Draft

Write the prose as plain markdown first, in your blog's source directory (the source of truth). Follow reference/voice.md and reference/craft.md as you write, so there's less to fix later. Keep it honest, concrete, and grounded in real project code. Vary sentence length. Have an opinion. If /direct-response-copy is available in your environment, run it on the title, description, and closing CTA (only those three surfaces, not the body).

5. Humanize (mandatory)

Run a humanizer pass on the draft: if /humanizer is available in your environment, invoke it on the draft. If it isn't available, apply the checklist in reference/voice.md yourself. Strip: significance inflation, promotional adjectives, the rule of three, "-ing" tail analyses, negative parallelisms ("it's not X, it's Y"), synonym cycling, hedging, and every dash. For headline/description/CTA polish you may also pull in /direct-response-copy if it's available.

Then run bash check.sh and fix anything it flags.

6. Wire it into the site

Follow reference/wiring.md. In short: register the post in whatever index/registry your blog uses, add the body in your blog's format, make sure the SEO surfaces (sitemap, RSS, OG/Twitter cards, JSON-LD) include the new post, add the cover image, and build. For keyword placement (title/description/first-H2/tags), internal-link count, and anchor-text rules, follow reference/seo.md. Add a reciprocal inbound link from the most related existing post.

7. Verify before done

Your site's build command must be green. Then smoke-test the post: confirm the post page, the cover image, the blog index, the sitemap, and the RSS feed all load and include the new post. View source on the post and confirm the meta description, OG/Twitter tags, and BlogPosting JSON-LD actually emitted with the right values (reference/seo.md lists what to check). Re-run bash check.sh on the final markdown. Only then is the post itself done.

8. Distribute (this is what earns the traction)

A correct post with no inbound links does not rank. After it ships, seed the first signal: if /x-tweet is available in your environment, run it on the post's core insight for a thread that teaches the idea and links the post; cross-link the post from the relevant docs; and answer the real question it solves where people are already asking it. See the distribution loop in reference/seo.md. Always link the canonical production URL (/blog/), never a staging or preview host.

Guardrails

• Never invent project APIs, flags, or numbers. Read the source and quote it.
• Never weaken the house voice to sound "professional." Concrete and a little contrarian

beats polished and generic every time.

• Don't ship a post whose angle overlaps a published one. Adjust the angle instead.
• Covers can be SVG or a raster image. Match your site's brand palette. If you can't make a

good cover, reuse an existing one rather than shipping something ugly.

Note on this skill's own files

The scanner will flag SKILL.md and the reference/ files because they name the banned characters (—) (–) and use → as teaching notation. That's expected. The scanner is for blog drafts and rendered post bodies, not for this skill's documentation.
