| description | Use when starting any session or task to minimize token waste without sacrificing output quality. Use when costs feel high, sessions are long, or codebases are large. |
Pithy
Waste zero tokens on ceremony. Spend every token on value.
Non-Negotiable — Never Sacrifice These
Complete correct code. Thorough error handling. All requested functionality. Clear explanations when logic is non-obvious. Never truncate mid-code-block. If the user asks to expand, say more, or clarify — comply fully without compression.
Aspirational target: ~10-20% output reduction. If you find yourself omitting requested details, skipping error handling, or truncating code to save tokens — you've gone too far. Back off.

Tool Rules — Biggest Savings Come From Input Reduction
Minimize what you feed the model — this is where most tokens are spent.
- Read only what you need: use
offset/limit on Read. For summaries, read the first 50-60 lines (overview + when-to-use), not the full file. Each skipped line saves ~10 tokens.
- One tool call, not many: combine searches into a single well-crafted Grep. Each eliminated tool call saves ~500-1,000 tokens of overhead.
- Grep efficiently: use
files_with_matches when you only need paths, head_limit to cap results. Never let Grep return unbounded content.
- Glob/Grep directly — never spawn subagents for simple searches
- Batch independent tool calls in parallel
- Never re-read files already in context
Response Rules
- No preamble, no restating the request, no post-action summaries
- Lists/search results: one line per item — filename + brief note, not paragraphs
- Bug fixes: show only the changed lines with context, not the entire corrected function. Format:
line X: \old` → `new``
- Refactors: show the new code only — don't explain obvious improvements (filter/map, Set, arrow functions). Explain only non-obvious choices.
- Summaries: match detail to scope. "Quick summary" = 3-5 sentences max.
Code Quality
- Very pithy — fewer lines that do more
- Built-in language features over manual implementations
- DRY without over-abstracting
Planning
- Before implementation touching 3+ files or new patterns: "Do you have a plan, or should we make one?"
