linkedin-post

A writing guide for drafting one daily LinkedIn post about a real business-development problem and supporting numbers from OmniRank. LinkedIn is a professional social network.

In plain words
What is it for?
Use it after a prospect conversation, surprising measurement, objection, tool result, or difficult decision. It helps turn that experience into a short post in S M Moshiur Rahman’s voice.
Why use it?
It avoids generic posts and made-up stories by requiring a real event, observation, or result before writing. This gives the post a specific basis.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

linkedin-post scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Daily LinkedIn post

Draft one post in Moshiur's voice. He is Director, Business & Operations at TICON System Limited — a practitioner writing about what he actually hit today, not a marketer.

The one rule

A post needs a real thing that happened. If he hasn't given you one, ask for it before drafting. Do not manufacture a scenario, and do not fall back on general SEO advice — that is the failure mode. Generic "5 tips for better SEO" content reads as filler, performs badly, and costs credibility that specific writing earns.

Acceptable raw material: a prospect conversation, an objection he couldn't answer, a measurement that surprised him, something he was wrong about, a tool result, a decision he had to make with incomplete information.

Structure that works

  1. A hook that is a fact, not a claim. Ideally a number or a short admission. "I ran our own website through a tool I built. 57 pages. Not one had an answer an AI could quote." Never open with "In today's digital landscape".
  2. The problem, stated concretely — what he actually ran into, in two or three short paragraphs. Short lines. LinkedIn truncates around 200 characters, so the first two lines carry the whole post.
  3. Evidence. Real numbers, indented as a small block. See below for pulling them.
  4. What he did or concluded — including the uncomfortable part if there is one.
  5. One specific question. Not "thoughts?" — something a reader can answer in a sentence from their own experience.
  6. Link only if it earns its place. github.com/bemoshiur/OmniRank when relevant.
  7. 4–7 hashtags, lowercase-natural, no keyword stuffing.

Target 1,300–2,000 characters. Longer gets collapsed behind "see more".

Getting real numbers

Never invent a statistic. When a post would benefit from data, measure it:

cd "<repo>" && .venv/bin/python -m omnirank.cli audit https://<site> --out /tmp/post.json

Then read /tmp/post.json for exact per-layer scores and finding counts. Quote what the tool actually printed. If a number can't be measured, cut the claim rather than soften it.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
