# lean-ctx — Context Engineering Layer

PREFER lean-ctx MCP tools over native equivalents for token savings:

| PREFER | OVER | Why |
|--------|------|-----|
| `ctx_read(path)` | Read / cat / head / tail | Session caching, 8 compression modes, re-reads cost ~13 tokens |
| `ctx_shell(command)` | Bash (shell commands) | Pattern-based compression for git, npm, cargo, docker, tsc |
| `ctx_search(pattern, path)` | Grep / rg | Compact context, token-efficient results |
| `ctx_tree(path, depth)` | ls / find | Compact directory maps with file counts |

## ctx_read Modes

- `full` — cached read (use for files you will edit)
- `map` — deps + API signatures (use for context-only files)
- `signatures` — API surface only
- `diff` — changed lines only (after edits)
- `aggressive` — syntax stripped
- `entropy` — Shannon + Jaccard filtering
- `lines:N-M` — specific range

## Edit Compatibility

If your Edit tool requires a prior native Read, use native Read for that file — then edit normally.
Write, StrReplace, Delete, Edit have no lean-ctx equivalent — use them normally.
Native tools are allowed as fallback — never get stuck.
