From ea170ab340e093c505f3bb03aeae5b9cecbd3f44 Mon Sep 17 00:00:00 2001 From: Shaun Arman Date: Fri, 5 Jun 2026 07:59:04 -0500 Subject: [PATCH] feat: add three-tier shell execution with kubectl support Introduce shell classifier, executor, kubeconfig manager, and kubectl binary management. Integrates with existing commands/agentic.rs primitives. - Add shell/classifier.rs: Three-tier safety classification (Tier 1: auto-execute, Tier 2: approve, Tier 3: deny) - Add shell/executor.rs: Command executor with approval gates - Add shell/kubeconfig.rs: kubeconfig parsing and management - Add shell/kubectl.rs: kubectl binary management - Add commands/shell.rs: Tauri IPC commands for shell execution - Update state.rs: Add pending_approvals field for approval flow - Update lib.rs: Register shell module and commands Co-Authored-By: Claude Sonnet 4.5 --- src-tauri/src/commands/mod.rs | 1 + src-tauri/src/commands/shell.rs | 234 ++++++++++++++ src-tauri/src/lib.rs | 10 + src-tauri/src/shell/classifier.rs | 517 ++++++++++++++++++++++++++++++ src-tauri/src/shell/executor.rs | 332 +++++++++++++++++++ src-tauri/src/shell/kubeconfig.rs | 179 +++++++++++ src-tauri/src/shell/kubectl.rs | 198 ++++++++++++ src-tauri/src/shell/mod.rs | 12 + src-tauri/src/shell/tests.rs | 22 ++ src-tauri/src/state.rs | 11 +- 10 files changed, 1515 insertions(+), 1 deletion(-) create mode 100644 src-tauri/src/commands/shell.rs create mode 100644 src-tauri/src/shell/classifier.rs create mode 100644 src-tauri/src/shell/executor.rs create mode 100644 src-tauri/src/shell/kubeconfig.rs create mode 100644 src-tauri/src/shell/kubectl.rs create mode 100644 src-tauri/src/shell/mod.rs create mode 100644 src-tauri/src/shell/tests.rs diff --git a/src-tauri/src/commands/mod.rs b/src-tauri/src/commands/mod.rs index b242ae8f..26af462d 100644 --- a/src-tauri/src/commands/mod.rs +++ b/src-tauri/src/commands/mod.rs @@ -5,4 +5,5 @@ pub mod db;
