whetstone
Whetstone is a collection of 20 reusable AI agent skills, each distilled from a single real production failure. The skills are designed to be loaded by AI coding agents like Claude Code to prevent common pitfalls in verification, design, safety, and diagnosis. Each skill includes a core rule, the sanitized case it came from, and a pre-flight checklist that gates 'done' and fails loudly when unchecked. The skills are client-agnostic and transferable across codebases and stacks. Installation is simple via a Claude Code plugin or manual copy of skill folders. The project is open-source under CC BY 4.0.

What Makes whetstone Different
Unique advantages vs similar tools in this niche
Skills are distilled from real production failures, not hypotheticals
vs Generic AI agent advice or best-practice guidesEach skill names the sanitized case it was distilled from, ensuring practical relevance.
Pre-flight checklists fail loudly
vs Suggestions that can be ignoredThe checklists gate 'done' and fail loudly when a box is unchecked, enforcing discipline.
Client-agnostic and transferable
vs Project-specific lessons that don't generalizeLessons are stripped to their mechanism so they transfer to any codebase or stack.
Frequently Asked Questions
Answers about setup, alternatives
whetstone integrates natively with Claude Code. These integrations enable agencies to connect whetstone into existing client workflows without custom development.
whetstone's most distinctive features include: Install via Claude Code plugin (Add the marketplace and install the plugin to get all 20 skills with auto-discovery.); Pre-flight checklists gate done (Each skill ends with a checklist that fails loudly when a box is unchecked.); Distill scars into skills (The 'Distill the Scar' skill provides a repeatable method for turning failures into reusable skills.). These capabilities differentiate whetstone from alternatives and create unique value for agency clients.
whetstone's key advantage over Generic AI agent advice or best-practice guides: Skills are distilled from real production failures, not hypotheticals. Each skill names the sanitized case it was distilled from, ensuring practical relevance. Overall: Whetstone provides a practical, battle-tested set of rules for improving AI coding agent reliability, distilled from real failures. It is particularly valuable for agencies that rely on AI agents for delivery, as it helps prevent costly mistakes. The open-source nature and low setup complexity make it easy to adopt.
whetstone is a strong fit if: Your agency uses AI coding agents for development and wants to reduce errors.; You need a structured way to capture and reuse lessons from production failures.; You value open-source, community-driven tools with no licensing costs.. Consider alternatives if: Your agency does not use AI coding agents.; You need a full-featured AI development platform rather than a skill pack.. Key trade-off: The skills are only useful if your agency uses AI coding agents like Claude Code; otherwise, they have limited applicability.
