From 2b334316370bf1c3eedd3b09549595120ff41521 Mon Sep 17 00:00:00 2001 From: Nick Nance Date: Mon, 16 Jun 2025 02:41:25 +0000 Subject: [PATCH 1/2] Add agent installation and management system (#391) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement comprehensive agent installation feature with support for: - Agent source resolution (catalog, git, URL, local) - Secure package downloading with caching - Agent validation and security checks - Dependency management for npm/pip/go packages - Complete CLI commands: add, list, remove agents - Example vector store agent template Features: • `agentuity add ` - Install agents from various sources • `agentuity add list` - List installed agents • `agentuity add remove ` - Remove installed agents • Comprehensive error handling with user-friendly messages • Security validation against malicious code patterns • Support for TypeScript, JavaScript, Python, and Go agents 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- cmd/add.go | 284 ++++++++++++++ examples/agent-example/README.md | 69 ++++ examples/agent-example/agent.yaml | 23 ++ .../agent-example/config/vector-store.yaml | 13 + examples/agent-example/src/types.ts | 24 ++ examples/agent-example/src/vector-store.ts | 76 ++++ internal/agent/agent_test.go | 181 +++++++++ internal/agent/downloader.go | 355 ++++++++++++++++++ internal/agent/errors.go | 226 +++++++++++ internal/agent/installer.go | 305 +++++++++++++++ internal/agent/resolver.go | 201 ++++++++++ internal/agent/types.go | 68 ++++ internal/agent/validator.go | 266 +++++++++++++ 13 files changed, 2091 insertions(+) create mode 100644 cmd/add.go create mode 100644 examples/agent-example/README.md create mode 100644 examples/agent-example/agent.yaml create mode 100644 examples/agent-example/config/vector-store.yaml create mode 100644 examples/agent-example/src/types.ts create mode 100644 examples/agent-example/src/vector-store.ts create mode 100644 internal/agent/agent_test.go create mode 100644 internal/agent/downloader.go create mode 100644 internal/agent/errors.go create mode 100644 internal/agent/installer.go create mode 100644 internal/agent/resolver.go create mode 100644 internal/agent/types.go create mode 100644 internal/agent/validator.go diff --git a/cmd/add.go b/cmd/add.go new file mode 100644 index 00000000..2ebd150e --- /dev/null +++ b/cmd/add.go @@ -0,0 +1,284 @@ +package cmd + +import ( + "context" + "fmt" + "os" + "path/filepath" + + "github.com/agentuity/cli/internal/agent" + "github.com/agentuity/cli/internal/errsystem" + "github.com/agentuity/cli/internal/project" + "github.com/agentuity/go-common/env" + "github.com/agentuity/go-common/logger" + "github.com/agentuity/go-common/tui" + "github.com/spf13/cobra" +) + +var addCmd = &cobra.Command{ + Use: "add [agent-name]", + Short: "Add an agent to your project", + Long: `Add an agent to your project from various sources. + +Sources can be: + - Catalog references: memory/vector-store, planner/task-decompose + - Git repositories: github.com/user/repo#branch path/to/agent + - Direct URLs: https://example.com/agent.zip + - Local paths: ./path/to/agent + +Examples: + agentuity add memory/vector-store + agentuity add github.com/user/agents#main my-agent + agentuity add ./local-agents/custom-agent + agentuity add --as custom-name memory/vector-store`, + Args: cobra.RangeArgs(1, 2), + Run: func(cmd *cobra.Command, args []string) { + l := env.NewLogger(cmd) + + // Get current directory as project root + projectRoot, err := os.Getwd() + if err != nil { + errsystem.New(errsystem.ErrListFilesAndDirectories, err, errsystem.WithContextMessage("Failed to get current directory")).ShowErrorAndExit() + } + + // Check if we're in a project directory + if !project.ProjectExists(projectRoot) { + errsystem.New(errsystem.ErrInvalidConfiguration, fmt.Errorf("agentuity.yaml not found"), errsystem.WithContextMessage("Not in an Agentuity project directory")).ShowErrorAndExit() + } + + source := args[0] + agentName := "" + if len(args) > 1 { + agentName = args[1] + } + + // Get flags + localName, _ := cmd.Flags().GetString("as") + if localName != "" { + agentName = localName + } + noInstall, _ := cmd.Flags().GetBool("no-install") + force, _ := cmd.Flags().GetBool("force") + cacheDir, _ := cmd.Flags().GetString("cache-dir") + + // Default cache directory + if cacheDir == "" { + homeDir, err := os.UserHomeDir() + if err != nil { + errsystem.New(errsystem.ErrListFilesAndDirectories, err, errsystem.WithContextMessage("Failed to get home directory")).ShowErrorAndExit() + } + cacheDir = filepath.Join(homeDir, ".config", "agentuity", "agents") + } + + if err := runAddCommand(context.Background(), l, source, agentName, projectRoot, cacheDir, noInstall, force);

2/2] Restructure agent installation as subcommands of agent (#391) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Move agent installation commands from root-level `add` to agent subcommands: • `agentuity add` → `agentuity agent add` • `agentuity add list` → `agentuity agent list-local` • `agentuity add remove` → `agentuity agent remove` This provides a more logical command structure where all agent-related operations are grouped under the `agent` command namespace, consistent with existing agent commands like `create`, `delete`, and `list`. Changes: - Remove cmd/add.go (standalone command) - Add agent installation subcommands to cmd/agent.go - Update command examples and help text - Maintain all existing functionality and flags 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- cmd/add.go | 284 --------------------------------------------------- cmd/agent.go | 259 ++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 259 insertions(+), 284 deletions(-) delete mode 100644 cmd/add.go diff --git a/cmd/add.go b/cmd/add.go deleted file mode 100644 index 2ebd150e..00000000 --- a/cmd/add.go +++ /dev/null @@ -1,284 +0,0 @@ -package cmd - -import ( - "context" - "fmt" - "os" - "path/filepath" - - "github.com/agentuity/cli/internal/agent" - "github.com/agentuity/cli/internal/errsystem" - "github.com/agentuity/cli/internal/project" - "github.com/agentuity/go-common/env" - "github.com/agentuity/go-common/logger" - "github.com/agentuity/go-common/tui" - "github.com/spf13/cobra" -) - -var addCmd = &cobra.Command{ - Use: "add [agent-name]", - Short: "Add an agent to your project", - Long: `Add an agent to your project from various sources. - -Sources can be: - - Catalog references: memory/vector-store, planner/task-decompose - - Git repositories: github.com/user/repo#branch path/to/agent - - Direct URLs: https://example.com/agent.zip - - Local paths: ./path/to/agent - -Examples: - agentuity add memory/vector-store - agentuity add github.com/user/agents#main my-agent - agentuity add ./local-agents/custom-agent - agentuity add --as custom-name memory/vector-store`, - Args: cobra.RangeArgs(1, 2), - Run: func(cmd *cobra.Command, args []string) { - l := env.NewLogger(cmd) - - // Get current directory as project root - projectRoot, err := os.Getwd() - if err != nil { - errsystem.New(errsystem.ErrListFilesAndDirectories, err, errsystem.WithContextMessage("Failed to get current directory")).ShowErrorAndExit() - } - - // Check if we're in a project directory - if !project.ProjectExists(projectRoot) { - errsystem.New(errsystem.ErrInvalidConfiguration, fmt.Errorf("agentuity.yaml not found"), errsystem.WithContextMessage("Not in an Agentuity project directory")).ShowErrorAndExit() - } - - source := args[0] - agentName := "" - if len(args) > 1 { - agentName = args[1] - } - - // Get flags - localName, _ := cmd.Flags().GetString("as") - if localName != "" { - agentName = localName - } - noInstall, _ := cmd.Flags().GetBool("no-install") - force, _ := cmd.Flags().GetBool("force") - cacheDir, _ := cmd.Flags().GetString("cache-dir") - - // Default cache directory - if cacheDir == "" { - homeDir, err := os.UserHomeDir() - if err != nil { - errsystem.New(errsystem.ErrListFilesAndDirectories, err, errsystem.WithContextMessage("Failed to get home directory")).ShowErrorAndExit() - } - cacheDir = filepath.Join(homeDir, ".config", "agentuity", "agents") - } - - if err := runAddCommand(context.Background(), l, source, agentName, projectRoot, cacheDir, noInstall, force);
