pi-lens gives AI coding agents fast, language-aware feedback while they write/edit.
- LSP diagnostics and navigation across supported languages
- Impact cascade diagnostics that show which related files were affected and run LSP diagnostics on them
- Language-specific linters, type-checkers, and scanners on every write/edit
- Safe formatting/autofix where tools are configured or confidently detected
- ast-grep and tree-sitter structural rules for correctness/security smells
- Agent-facing tools for LSP navigation/diagnostics, AST search/replace, diagnostics state, and project intelligence
- Review-graph intelligence for supported languages via bundled tree-sitter WASMs
- Read-guard and edit-autopatch support to reduce bad edits
- Background security/dependency scans for opted-in projects
