## Usage via Shell
Run lean-ctx commands through your Shell/Bash tool:
```
lean-ctx read src/main.rs
lean-ctx read src/main.rs -m signatures
lean-ctx -c \"cargo test\"
lean-ctx grep \"fn main\" src/
lean-ctx ls src/
```
## Read modes (same as MCP):

# lean-ctx — Context Engineering Layer
The workspace has the `lean-ctx` MCP server installed. You MUST prefer lean-ctx tools over native equivalents for token efficiency and caching.
## Mandatory Tool Preferences
| Use this | Instead of | Why |
|----------|-----------|-----|
| `mcp_lean_ctx_ctx_read` | `readFile`, `readCode` | Cached reads, 10 compression modes, re-reads cost ~13 tokens |
| `mcp_lean_ctx_ctx_multi_read` | `readMultipleFiles` | Batch cached reads in one call |
| `mcp_lean_ctx_ctx_shell` | `executeBash` | Pattern compression for git/npm/test output |
| `mcp_lean_ctx_ctx_search` | `grepSearch` | Compact, .gitignore-aware results |
| `mcp_lean_ctx_ctx_tree` | `listDirectory` | Compact directory maps with file counts |
## When to use native Kiro tools instead
- `fsWrite` / `fsAppend` — always use native (lean-ctx doesn't write files)
- `strReplace` — always use native (precise string replacement)
- `semanticRename` / `smartRelocate` — always use native (IDE integration)
- `getDiagnostics` — always use native (language server diagnostics)
- `deleteFile` — always use native
## Session management
- At the start of a long task, call `mcp_lean_ctx_ctx_preload` with a task description to warm the cache
- Use `mcp_lean_ctx_ctx_compress` periodically in long conversations to checkpoint context
- Use `mcp_lean_ctx_ctx_knowledge` to persist important discoveries across sessions
## Rules
- NEVER loop on edit failures — switch to `mcp_lean_ctx_ctx_edit` immediately
- For large files, use `mcp_lean_ctx_ctx_read` with `mode: \"signatures\"` or `mode: \"map\"` first
- For re-reading a file you already read, just call `mcp_lean_ctx_ctx_read` again (cache hit = ~13 tokens)
- When running tests or build commands, use `mcp_lean_ctx_ctx_shell` for compressed output
