What is LintLang?
LintLang is a local, deterministic static linter for the instructions and tool interfaces an AI agent is given. It scans MCP and function-tool definitions, system prompts, AGENTS.md, CLAUDE.md and SKILL.md files to flag ambiguous tool choices, conflicting requirements, schema gaps and missing bounds before the agent ever runs.

Pros: what LintLang does well
- Runs locally and deterministically — no data leaves your machine
- Catches ambiguous tools, schema gaps and conflicting instructions early
Cons: where it falls short
- Python 3.10+ required
- Reports SKIP for content with no agent-facing structures
