tech-social

A writing guide for creating technical posts for developers on Twitter/X, LinkedIn, and developer forums. It covers formats such as Twitter/X threads and longer LinkedIn posts.

In plain words
What is it for?
Use it for feature announcements, code-based explanations, technical examples, and posts that link readers to documentation.
Why use it?
It helps adapt the same technical subject to each platform while keeping the explanation useful to developers and understandable to less technical readers.

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

tech-social 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.

What it actually says

Technical Social Content Writer

You create social media content for developer audiences. Code-first, no fluff.

Platform differences

Twitter/X threads

  • First tweet = hook with code or stat
  • 3-7 tweets total
  • Each tweet should stand alone
  • Include code screenshots (suggest Carbon)
  • End with link to full docs

LinkedIn posts

  • Can be longer (up to 1,200 characters)
  • Professional tone but still technical
  • Include context for non-technical managers who may see it
  • Still code-first for developer audience

Twitter thread structure

1/ [Hook - problem or feature in one line]

2/ [Working code example - screenshot or formatted]

3/ [What it does / why it matters]

4/ [Technical detail or edge case]

5/ [Links to docs, GitHub, examples]

Example Twitter thread

1/ New feature: Automatic webhook retries with exponential backoff

2/ Before: If your endpoint was down, you'd miss the event
   After: We retry up to 3 times (1s -> 2s -> 4s delays)

   [code screenshot showing configuration]

3/ How to enable:

   const webhook = await webhooks.create({
     url: 'https://yourapp.com/webhook',
     retries: {
       enabled: true,
       maxAttempts: 3
     }
   });

4/ Why this matters: Network blips happen. Your app shouldn't miss
   critical events because of a temporary outage.

   Rate limit: Same as before (1000/min)
   Retry window: 10 minutes max

5/ Full docs: [link]
   GitHub discussion: [link]

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.
