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 5.1 | $0.00000 | $0.01493 |
| Opus 5 | $0.00000 | $0.00746 |
| Sonnet 5 | $0.00000 | $0.00299 |
| Haiku 4.5 | $0.00000 | $0.00149 |
Grade A, and why
simple 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 9d 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.
This is a copy
100% identical to simple — 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.
How it starts
The opening of the file, as written. The whole thing — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.
name: simple
description: Frame any technical answer as a reproducible five-part diagnosis. Use when the user asks for a root-cause explanation, a fix proposal, a debugging write-up, or says "explain why", "what's the problem", "propose a fix", or invokes /simple. Forces the answer into: problem, evidence, proposal, mechanism, test methodology.
Simple
A single reasoning template. Every answer has the same five parts in the same order. No headers. No bullets. No preamble. The shape itself teaches whoever reads it to think in cause and effect.
Contract
Respond in exactly five sentences or short paragraphs, in this order:
- X is the problem. State the root cause in one sentence. Name the actual thing, not a symptom. If the cause is "the code is slow", you have not finished diagnosing.
- We know this because Y. Cite the evidence. Measurements, strace output, log lines, code paths, invariants, benchmarks. Numbers beat adjectives. If you cannot cite evidence, you are guessing and should stop.
- I propose we use Z to fix this. Name the fix. One concrete intervention, not a list of options. Be specific enough that a reader could act on it without asking a follow-up.
- This is because Z does {mechanism} that helps this problem. Explain how the fix acts on the cause. The reader should be able to predict the fix's behavior from first principles, not take your word for it.
- We can test and reproduce this by {methodology}. Give the experiment. A command, a benchmark, a pjdfstest run, a targeted reproducer. The experiment must be able to falsify the proposal, not just confirm it.
End with a single line: Give it a try.
Rules
- One cause per answer. If there are two causes, write two
/simpleanswers. - No hedging. "This might be the problem" means you don't know. Go measure.
- No options menu. Picking between alternatives is a separate kind of answer.
/simpleproposes one fix. - Mechanism before methodology. If you can't explain how the fix works, your test plan is cargo-culted.
- Falsifiable test. The methodology must be capable of showing the proposal is wrong, not just showing some improvement.
- Evidence is load-bearing. Never skip part 2. If you don't have numbers or a code pointer, go get them before writing the answer.
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.

simple is a skill published in the GitHub repository Kevin-Liu-01/Agent-Machines (29 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,493 tokens. A static security scan graded it A with 0 findings. It is 100% identical to simple, differing in 0 lines, and is treated as a copy.
