A Claude Code plugin that makes AI coding agents follow engineering discipline. Plan before coding. Verify before claiming done. Find root cause before patching. Review before merge. Skills activate based on file type and task signals, not manual toggling.
Bundles agents, skills, workflow commands, and a skill distillery for PHP, Python, TypeScript, React, and infrastructure workflows.
Who this is for
Teams using Claude Code for real work. You build with PHP, Python, TypeScript, or React and want the agent to plan before building, verify before shipping, and debug from evidence.
Solo developers who want consistency. Bash tasks receive guidance on strict mode and ShellCheck; Laravel tasks receive strict-type and thin-controller patterns. Skills guide the agent; only checks actually run can establish compliance.
Anyone building with AI agents. Includes skills for multi-agent orchestration, agent-native architecture design, and a distillery that generates new skills from top-rated community sources.
The problem
AI coding agents skip planning, claim "done" without verifying, patch symptoms over root causes, and forget what they learned when context resets. The output looks polished even when the process behind it is missing.
The long-form argument is at AI Agents Don't Lack Capability. They Lack Process.. This plugin supplies that

Questions
What is the Whetstone MCP server?
AI-powered development tools. 18 agents, 19 commands, 29 skills, 1 hook, 1 MCP server for code review, research, design, and workflow automation.
What tools does Whetstone expose?
7 in total: 5 read-only, 2 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is Whetstone safe to connect to an agent?
No — not without reading the findings first. The audit graded it F (35/100) and found 8 critical or high issues in the source. Each one is listed on this page with the file and line it is on.
What credentials does Whetstone need?
It reads AZURE_OPENAI_API_KEY, AZURE_OPENAI_AUTH_MODE, AZURE_OPENAI_OPTIMIZER_API_KEY, AZURE_OPENAI_OPTIMIZER_AUTH_MODE, AZURE_OPENAI_TARGET_API_KEY, AZURE_OPENAI_TARGET_AUTH_MODE, CLAUDE_CODE_EXEC_MAX_THINKING_TOKENS, GROK_API_KEY, OPENROUTER_API_KEY, OPTIMIZER_AZURE_OPENAI_API_KEY, OPTIMIZER_AZURE_OPENAI_AUTH_MODE and QUOTED_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How current is this page?
The grade is for one exact copy of the source (93398457630b), read on 2026-10-08. The repository is watched and re-audited when it changes.
