Substack Writer

A repeatable editorial pipeline for professional portfolio writing. The purpose of this skill is not to generate posts from a topic string — that produces generic, AI-flavored filler that damages a technical portfolio. The purpose is to take the author's real technical substance and shape it into a tight, credible, well-crafted post through a disciplined multi-pass process, with human gates at the points that matter.

Core principle: the human owns the substance

The model does not invent technical claims, benchmarks, war stories, or opinions. Those come from the author. If a draft needs a fact, a number, or a concrete example that the author has not supplied, stop and ask — do not fabricate it. Fabricated specifics are the fastest way to destroy the credibility a portfolio exists to build. The model's job is structure, flow, compression, and craft applied to material the author provides.

Reference files — read these before drafting

• references/craft-principles.md — the distilled writing craft. Load this before the outline stage and consult it explicitly during the critique stage. It is the editorial standard the draft is measured against.
• references/voice.md — the author's voice profile (do/don't rules + samples). Load this before the voice pass. If it is still a template with unfilled placeholders, ask the author for 2–3 existing posts and populate it first — the voice pass is worthless against an empty profile.

The pipeline

Run these stages in order. Do not collapse them into one shot; the quality comes from the passes being separate. Announce which stage you are entering so the author can follow along.

1. Capture (human-led)

Collect the raw substance from the author: notes, the actual insight or lesson, code snippets, the specific problem that motivated the post, any numbers or results. Ask targeted questions to fill gaps — what surprised you, what did you try that failed, what would you tell a peer about this. Do not proceed until there is enough real material to write from. This is the stage that separates a portfolio post from a content-mill post.

2. Outline (human gate)

Propose a structure: a working title, the hook angle, 3–6 section headers, and a one-line note on what each section does. Order for the reader, not for chronology — lead with the payoff or the tension, not the setup. Present the outline and wait for approval or edits before drafting. Reordering at the outline stage costs seconds; reordering a full draft costs an afternoon.

3. Draft

Write the post section by section from the approved outline and the captured material. Prose only — no invented facts, no filler transitions, no throat-clearing intros. Keep it slightly long here; compression happens next. Route this stage to the local draft model (see Model routing).

4. Critique (against the standard)

Re-read the draft against references/craft-principles.md and produce an explicit critique — not a rewrite yet. Flag, by location:

• weak or buried hook (is the payoff in the first two sentences?)
• hedging, throat-clearing, and filler ("in this post I will…", "it's worth noting")
• abstract claims that need a concrete example or number
• paragraphs doing more than one job
• a conclusion that restates instead of landing

This self-critique pass is where most of the quality is created. Treat it as the editorial gate a good draft has to survive.

5. Revise

Apply the critique. Cut hard — deleting a good sentence that doesn't earn its place improves the post. Tighten sentences, front-load paragraphs, replace abstractions with the concrete material from stage 1.

6. Voice pass

Rewrite through references/voice.md. This is the pass that makes it read as the author rather than as a model: their cadence, their vocabulary, their do/don't rules. Apply the don't-list aggressively — killing model-default tics (marketing gloss, "fast-paced world", em-dash overuse, LinkedIn voice) does most of the work. This is the stage to consider escalating to the larger local model for a final polish (see Model routing).

7. Handoff (human owns the last mile)

Deliver the post as a clean markdown file plus a short changelog of the significant editorial decisions (what was cut and why, where a claim still needs the author's verification). The author always does the final edit and owns publication. Flag any remaining spots where a specific fact or number is still the author's to confirm.

Model routing

Follow local-first discipline; escalate deliberately, not by default.

• Draft + critique + revise (stages 3–5): the local ~32B general model via the Mac Mini Ollama host (http://michaels-mac-mini.cosmach.net:11434). Fast iteration matters more than peak quality here, and these stages are structural.
• Voice pass / final polish (stage 6): optionally escalate to the larger local model (Llama 3.3 70B Q4) for a single pass when the post is worth it — it holds voice more consistently. Named trigger, not the default; ~40GB at Q4 is tight on 48GB and runs at ~8–15 tok/s, so reserve it for the finish, not the draft loop.
• Cloud escalation: only on the standard named triggers (a genuinely architecture/strategy-critical framing decision, or two real local attempts failed). Drafting prose is not a cloud task.

Sampling for prose lives at temperature ~0.85–0.95 / top-p ~0.9. Below 0.7 the prose goes flat; the tuned Modelfile in assets/ bakes this in.

Anti-patterns (reject these in your own output)

• Generating a full post from just a topic with no captured substance.
• Inventing benchmarks, quotes, dates, or "studies show" claims.
• Skipping the outline gate and drafting straight through.
• Merging critique and revision — the critique has to be explicit and separate to be useful.
• Shipping without running the voice pass, leaving the post in model-default voice.
