Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is Fmarzochi/EGC's own configuration. It tells Codex how to work on EGC itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything EGC configures →

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

article-writing 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 8d 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 — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Article Writing

Write long-form content that sounds like an actual person with a point of view, not an LLM smoothing itself into paste.

When to Activate

  • drafting blog posts, essays, launch posts, guides, tutorials, or newsletter issues
  • turning notes, transcripts, or research into polished articles
  • matching an existing founder, operator, or brand voice from examples
  • tightening structure, pacing, and evidence in already-written long-form copy

Core Rules

  1. Lead with the concrete thing: artifact, example, output, anecdote, number, screenshot, or code.
  2. Explain after the example, not before.
  3. Keep sentences tight unless the source voice is intentionally expansive.
  4. Use proof instead of adjectives.
  5. Never invent facts, credibility, or customer evidence.

Voice Handling

If the user wants a specific voice, run brand-voice first and reuse its VOICE PROFILE. Do not duplicate a second style-analysis pass here unless the user explicitly asks for one.

If no voice references are given, default to a sharp operator voice: concrete, unsentimental, useful.

Banned Patterns

Delete and rewrite any of these:

  • "In today's rapidly evolving landscape"
  • "game-changer", "cutting-edge", "revolutionary"
  • "here's why this matters" as a standalone bridge
  • fake vulnerability arcs
  • a closing question added only to juice engagement
  • biography padding that does not move the argument
  • generic AI throat-clearing that delays the point

Writing Process

  1. Clarify the audience and purpose.
  2. Build a hard outline with one job per section.
  3. Start sections with proof, artifact, conflict, or example.
  4. Expand only where the next sentence earns space.
  5. Cut anything that sounds templated, overexplained, or self-congratulatory.

Structure Guidance

Technical Guides

  • open with what the reader gets
  • use code, commands, screenshots, or concrete output in major sections
  • end with actionable takeaways, not a soft recap

Essays / Opinion

  • start with tension, contradiction, or a specific observation
  • keep one argument thread per section
  • make opinions answer to evidence

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.
