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

write 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 yesterday.

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.

The opening of the file, as written. The whole thing — 521 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Writing Style Skill

Expert writing for technical content, social media, and developer documentation. Optimized to avoid AI detection patterns.


How to call specific sections

Use these triggers to activate specific parts of this skill:

Trigger phrase Section activated
write:tweet or write:x X/Twitter posts format
write:linkedin LinkedIn posts format
write:blog Blog posts format
write:readme README files format
write:commit Git commits format
write:docs Developer documentation
write:feature Feature post format
write:convex Convex-specific content
write:tip Quick tip format

Example usage:

  • "write:tweet about Convex real-time sync"
  • "write:blog on authentication patterns"
  • "write:feature for our new search API"

Rule of one

Every piece of content follows this framework:

One person: Write to a specific person, not an audience.

One problem: State the single problem they face.

One cause: Identify the root cause.

One difference: Explain what the solution does differently.

One action: End with one clear next step.

Rule of one checklist

Before publishing, answer these:

  • Can I name the one person this is for?
  • Can the problem fit in one sentence?
  • Is the root cause obvious?
  • Can I explain the difference in one breath?
  • Is there only one action at the end?

If any answer is no, revise before publishing. Ask the user if they want to proceed with the revision.


When to use this skill

Activate for:

  • X/Twitter posts
  • LinkedIn content
  • Blog posts
  • README files
  • Git commits
  • Product announcements
  • Developer documentation
  • Feature posts

Important: This is for standalone writing. Don't update project files (files.md, changelog.md, README.md) when using this skill.

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.
