🤖 AGENTS.md Linter
Lint your AGENTS.md (or CLAUDE.md and .cursorrules) for the problems that make a coding agent misbehave. Flags contradictory rules, references to files and commands that no longer exist, overly broad or unsafe instructions, missing sections (build, test, run, conventions), duplicate rules, and the case where you have competing rule files that should be consolidated into one AGENTS.md.

About this skill
Optimized Agent Instruction Linting
Maintaining clear and consistent instructions for AI agents is critical for reliable development workflows. The AGENTS.md Linter provides a rigorous analysis of your configuration files (AGENTS.md, CLAUDE.md, .cursorrules) to ensure your AI isn't being slowed down by conflicting commands or stale context.
What it does
This skill scans your repository's instruction files against your actual codebase to identify breaking issues. It goes beyond simple text checking by cross-referencing your project's package.json, Makefile, and source files to verify that the commands your agents are told to run actually exist.
- Detects conflicting rules that cause agent "hallucination" or refusal.
- Flags stale file paths and obsolete terminal commands.
- Identifies overly broad or unsafe instructions that could compromise code quality.
- Suggests consolidation strategies when multiple competing rule files are found.
Why use this skill
Unlike basic prompting, this tool uses specific rule IDs (AML001-AML007) and manifest scanning to provide high-precision feedback. It prevents the common "instruction bloat" that leads to context window waste and ensures your Cursor, Claude, or Copilot agents remain surgical and efficient.

Creator
JustHandled Labs builds focused agent skills for the work nobody wants to do by hand. Each one is a single repeatable job done well: catching the security and data mistakes that quietly ship, keeping docs and tests honest, gating the commands an agent is about to run, sharpening writing, and handling the founder chores around launches, outreach, and brand setup. Not generic AI productivity. Specific workflows that are easy to run, review, and repeat. Maintained by H.J. Westerfield, with a background in communications, editing, project coordination, customer support, and practical AI systems. Tools for people who want useful automation without theatrical complexity.

Architects the right retrieval strategy for every query — teaching your agent when to use RAG, a knowledge graph, or a temporal index instead of defaulting to vector search for everything.
synthesizing-institutional-knowledge
Builds the organizational memory schema your AI agent needs to answer why — capturing decision provenance, causal chains, and event context that embedding-based retrieval permanently discards.
