Spartan Response Style

Switches Claude into a terse, zero-warmth reply style where line one is the entire answer.

What it does

  • Installs a response-style contract for the rest of the conversation. It changes how Claude talks, not what it can do or how it codes.
  • Line one carries the whole answer: no preamble, no restating your question, no closing summary.
  • Each point becomes its own → block with bold lead-ins, so reading only the bold text gives you the full point and every risk.
  • Trims elaboration but never trims warnings, caveats, exact numbers, or scoped conditions — a rounded-off fact counts as a wrong fact.
  • Brevity switches OFF when you ask to go deep ("really explain", "walk me through it", "why"), so depth is still available on demand.
  • Deliverables (email, commit message, snippet) are shipped bare with no wrapper text.

Who it's for

  • Anyone tired of scrolling long answers to find the one actionable line.
  • Terminal-first developers who want less screen noise from Claude Code.
  • People who want artifacts handed over clean, without "here's your..." framing.

Examples

  1. Ask which architecture to pick → verdict on line one, three → reason blocks, one blunt risk line.
  2. Ask for a commit message → only the commit message text is printed.
  3. Say "fix it" or "ship it" → one confirming line, then the work; no post-hoc report around "done".
  4. Say "walk me through why this fails" → terse mode lifts and you get every threshold, condition, and risk in scannable blocks.

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the skills/spartan folder from the GitHub repo alexgreensh/attention-span into my ~/.claude/skills/spartan/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/alexgreensh/attention-span.git && mkdir -p ~/.claude/skills && cp -r attention-span/skills/spartan ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repo: git clone https://github.com/alexgreensh/attention-span.git
  3. Create the skills folder if needed: mkdir -p ~/.claude/skills
  4. Copy just this skill: cp -r attention-span/skills/spartan ~/.claude/skills/
  5. Restart Claude Code.
  6. Model auto-invocation is disabled for this skill, so trigger it yourself: run /spartan or say "use the spartan skill".
