Included Skills6

skinflintskills/skinflint/SKILL.md

Spend fewer tokens on every turn: short direct prose, the smallest code change that works, and narrow reads. Switch on with /skinflint or "skinflint on"; off with "stop skinflint" or "normal mode". Use when the user asks for skinflint, terse answers, minimal code, or less token use.

skinflint-auditskills/skinflint-audit/SKILL.md

Read-only audit of a diff, file or repository for things that cost tokens without earning them, in code and in prose, ranked by size. Use for "/skinflint-audit", "skinflint audit", "what can I cut", or "audit this for bloat".

skinflint-debtskills/skinflint-debt/SKILL.md

List every deliberate shortcut marked with a `skinflint:` comment in the repository, so skipped work is tracked instead of forgotten. Use for "/skinflint-debt", "skinflint debt" or "what did we skip".

skinflint-helpskills/skinflint-help/SKILL.md

Show the skinflint commands and settings. Use for "/skinflint-help", "skinflint help" or "how do I use skinflint".

skinflint-reviewskills/skinflint-review/SKILL.md

Review a diff or file for code that can be deleted or made simpler. One line per finding, no praise. Use for "/skinflint-review", "skinflint review" or "review this for bloat".

skinflint-statsskills/skinflint-stats/SKILL.md

Show how much tool output skinflint has trimmed so far. Use for "/skinflint-stats", "skinflint stats" or "how much has skinflint saved".
