Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00000 | $0.00411 |
| Opus 5 | $0.00000 | $0.00205 |
| Sonnet 5 | $0.00000 | $0.00082 |
| Haiku 4.5 | $0.00000 | $0.00041 |
Grade A, and why
codex 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.
What it actually says
Codex CLI
Install
Add the no-slop rules to your Codex system prompt. Create or edit your AGENTS.md or system instruction file:
Option 1: Clone and reference
git clone https://github.com/Byk3y/no-slop.git ~/.no-slop
Then add to your Codex instructions:
When writing prose, follow the rules in ~/.no-slop/SKILL.md
Option 2: Inline rules
Add the following to your Codex system prompt or instructions.md:
# no-slop rules for prose writing
When writing any prose (docs, emails, READMEs, PR descriptions):
1. BANNED WORDS: Never use: delve, tapestry, pivotal, vibrant, meticulous, landscape (metaphorical), testament, underscore, intricate, interplay, garner, bolster, foster, showcase, emphasize, crucial, enhance, leverage, utilize, facilitate, streamline, robust (in prose), seamless, holistic, synergy, paradigm, ecosystem (metaphorical), groundbreaking, renowned, profound, comprehensive.
2. COPULAS: Use "is/are/has." Not "serves as," "stands as," "boasts," "features."
3. NO STRUCTURAL FORMULAS: No rule-of-three. No "not only X but also Y." No "challenges and future prospects" endings.
4. NO PARTICIPLE CHAINS: Cut "-ing" filler words (highlighting, showcasing, emphasizing).
5. NO PROMOTIONAL TONE: State facts. No hype. No vague attributions.
6. NO COLLABORATIVE LANGUAGE: No "let's explore," "we will examine."
7. FORMATTING: Minimal bold. No emoji. Sentence-case headings.
8. WRITE LIKE A HUMAN: Vary sentence length. Use contractions. Be specific.

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.

codex is an agent published in the GitHub repository Byk3y/no-slop (10 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 411 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
