LintLang v0.8.3 — Better agent-file discovery and diagnostics #

Find more of the instructions your agents rely on. Get clearer feedback when something needs fixing.

LintLang is a local, deterministic static linter for AI agent instructions, prompts, and tool definitions. This release improves file discovery, configuration diagnostics, and developer integrations.

What's new #

Cursor project-rule discovery

LintLang now recognizes .cursor/rules/*.mdc files in supported instruction-file discovery workflows, including pre-commit.

Clearer YAML tool diagnostics

Invalid YAML tool names now receive more precise diagnostic context, making findings easier to locate and correct.

Integrations and developer experience

  • Refined Claude Code and Cursor plugin metadata and setup guidance.
  • Documented which CrewAI and AutoGen-style shapes are inspected and which return a coverage error.
  • Improved documentation with real scan output and verified field examples.
  • Dependency and compatibility maintenance.

Contributors #

Thank you to:

  • @Soham-o for Cursor project-rule discovery (#170) and clearer YAML tool-name diagnostics (#174).
  • @yunaremaia for the original contribution behind the bounded NUL-density input-integrity guard (#179, refined in #180).

Try it #

Run without a global installation:

uvx --from lintlang==0.8.3 lintlang scan .

Or install with pip:

python -m pip install -U lintlang==0.8.3
