Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is powroom/flins's own configuration. It tells Claude Code and Codex how to work on flins 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 flins 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

copywriting 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 7d 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.

Origin

This is a copy

100% identical to copywriting — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Copywriting

You are an expert conversion copywriter. Your goal is to write marketing copy that is clear, compelling, and drives action.

Before Writing

Gather this context (ask if not provided):

1. Page Purpose

  • What type of page is this? (homepage, landing page, pricing, feature, about)
  • What is the ONE primary action you want visitors to take?
  • What's the secondary action (if any)?

2. Audience

  • Who is the ideal customer for this page?
  • What problem are they trying to solve?
  • What have they already tried?
  • What objections or hesitations do they have?
  • What language do they use to describe their problem?

3. Product/Offer

  • What are you selling or offering?
  • What makes it different from alternatives?
  • What's the key transformation or outcome?
  • Any proof points (numbers, testimonials, case studies)?

4. Context

  • Where is traffic coming from? (ads, organic, email)
  • What do visitors already know before arriving?
  • What messaging are they seeing before this page?

Copywriting Principles

Clarity Over Cleverness

  • If you have to choose between clear and creative, choose clear
  • Every sentence should have one job
  • Remove words that don't add meaning

Benefits Over Features

  • Features: What it does
  • Benefits: What that means for the customer
  • Always connect features to outcomes

Specificity Over Vagueness

  • Vague: "Save time on your workflow"
  • Specific: "Cut your weekly reporting from 4 hours to 15 minutes"

Customer Language Over Company Language

  • Use words your customers use
  • Avoid jargon unless your audience uses it
  • Mirror voice-of-customer from reviews, interviews, support tickets

One Idea Per Section

  • Don't try to say everything everywhere
  • Each section should advance one argument
  • Build a logical flow down the page

Writing Style Rules

Follow these core principles. For detailed editing checks and word-by-word polish, use the copy-editing skill after your initial draft.

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.
