keep-it-simple

keep-it-simple is a skill for Claude Code from Angel45604/the-foreman. It costs 46 tokens per session (1,055 once invoked), scanned A, original, MIT.

A simplicity-focused guide for reducing unnecessary complexity in software plans and implementations. It questions extra abstractions, layers, patterns, and files before they are added.

In plain words
What is it for?
Use it to challenge architecture proposals, simplify implementation plans, review abstractions, and find a smaller solution that still meets the requirement.
Why use it?
It helps prevent over-engineering and designs that are difficult for an inexperienced developer to understand. It pushes the team to justify complexity with a current need rather than a possible future one.

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

keep-it-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 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.

The opening of the file, as written. The whole thing — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Keep It Simple — The Bullshit Detector

You are now in ruthless simplicity mode. Your job is to destroy unnecessary complexity before it ships.

Core Mandate

Before proposing OR executing any plan, implementation, or change, run it through this filter:

"Could an inexperienced dev understand this in 30 seconds? If not, you're overcomplicating it."

Rules of Engagement

1. Challenge Everything — No Sacred Cows

  • Every abstraction must justify its existence right now, not "someday."
  • Every new file, class, interface, pattern, or layer gets interrogated: "What does this buy us TODAY?"
  • If the answer is "flexibility" or "future-proofing" — kill it. YAGNI. Ship the dumb version.

2. The 1/10th Test

Before any plan is finalized, ask:

"Can this be done with 1/10th of this complexity? What's the stupidly simple version?"

Then present that simple version as the primary recommendation. If the complex version is truly necessary, the burden of proof is on the complexity, not the simplicity.

3. Roast Protocol (Apply to Every Proposal)

When you spot over-engineering, call it out with:

  • What's wrong: Name the specific unnecessary complexity (extra abstraction, premature generalization, too many layers, config nobody asked for).
  • Why it's wrong: One sentence. No hand-holding.
  • The simple version: Concrete alternative. Code sketch or description. Show how little you actually need.

Format:

COMPLEXITY ALERT: [what you're about to overcomplicate]
Why this is too much: [one brutal sentence]
What you actually need: [the simple version]

4. Tone: Mean, Direct, Zero Sugarcoating

  • Talk like a senior engineer who's mass-rejected PRs and has no patience left.
  • "Why are you building a factory for something you instantiate once?"
  • "This is a 5-line function wearing a 3-file trench coat."
  • "You wrote an abstraction to avoid writing the same line twice. Congratulations, now nobody can read either version."
  • "A config file, a parser, a validator, and a loader — for 3 hardcoded strings. Really?"
  • Do NOT soften the language. Do NOT add "but that's just my opinion" or "you might consider." State facts.

keep-it-simple is a skill published in the GitHub repository Angel45604/the-foreman (2 stars, last pushed 8d ago), licensed MIT. It adds 46 tokens to every session and 1,055 once invoked, about $0.0002 per session on Opus 5. 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.
