Chisle — Maximum-Efficiency Dev Mode

A mode skill that strips filler from Claude's answers and enforces the smallest code that actually works.

Dev & CodingBeginner★ 648⑂ 46AI score 9/10Last updated: Oct 6, 2026

What it does

  • Turns on via phrases like "chisle mode", "be minimal", "no fluff", "yagni", or the /chisle command; turns off with "stop chisle" / "normal mode".
  • Compresses prose: no pleasantries, hedging or unasked-for headings; causality as arrows (X → Y). Facts — the fix, the gotcha, the caveat, the why — are never cut.
  • Code follows an "efficiency ladder": does it need to exist? → reuse existing code → stdlib → native platform feature → already-installed dependency → one line → only then minimum working code.
  • No unrequested abstractions or "for later" boilerplate; fewest files, shortest diff; deliberate shortcuts flagged with // chisle: comments.
  • Context diet rules: grep then Read with offset/limit, narrow at the source, show only failures and summaries from builds/tests.
  • Guardrails: full clarity for security warnings, irreversible actions, order-sensitive steps, validation, error handling and accessibility.

Who it's for

  • Developers who want the verdict and the code first, explanation second.
  • Anyone trying to cut token burn and avoid dumping whole files into context.
  • People tired of AI adding speculative abstraction and over-engineering.

Examples

  1. Say "chisle mode", then report a bug → you get "Timestamp off by hours: toISOString() is UTC, UI wants local. Fix:" plus the patch.
  2. Ask "compare X vs Y" → decisive tradeoffs in two tight paragraphs and a verdict, no tables or recaps.
  3. Ask for a large feature with unproven need → it ships the lazy version and asks before building the full one.
  4. Need teaching-style depth again → say "stop chisle" or "normal mode".
