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

stop-slop 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 3d 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

92% identical to stop-slop — 5 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.

What it actually says

Stop Slop

Eliminate predictable AI writing patterns from prose.

Core Rules

  1. Cut filler phrases. Remove throat-clearing openers and emphasis crutches. See references/phrases.md.

  2. Break formulaic structures. Avoid binary contrasts, dramatic fragmentation, rhetorical setups. See references/structures.md.

  3. Vary rhythm. Mix sentence lengths. Two items beat three. End paragraphs differently.

  4. Trust readers. State facts directly. Skip softening, justification, hand-holding.

  5. Cut quotables. If it sounds like a pull-quote, rewrite it.

Quick Checks

Before delivering prose:

  • Three consecutive sentences match length? Break one.
  • Paragraph ends with punchy one-liner? Vary it.
  • Em-dash before a reveal? Remove it.
  • Explaining a metaphor? Trust it to land.

Scoring

Rate 1-10 on each dimension:

Dimension Question
Directness Statements or announcements?
Rhythm Varied or metronomic?
Trust Respects reader intelligence?
Authenticity Sounds human?
Density Anything cuttable?

Below 35/50: revise.

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
