* feat(mcp): add workspace root validation to prevent path traversal - Add workspaceRoot field to Service for restricting file operations - Add WithWorkspaceRoot() option for configuring the workspace directory - Add validatePath() helper to check paths are within workspace - Apply validation to all file operation handlers - Default to current working directory for security - Add comprehensive tests for path validation Closes #82 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * refactor: move CLI commands from pkg/ to internal/cmd/ - Move 18 CLI command packages to internal/cmd/ (not externally importable) - Keep 16 library packages in pkg/ (externally importable) - Update all import paths throughout codebase - Cleaner separation between CLI logic and reusable libraries CLI commands moved: ai, ci, dev, docs, doctor, gitcmd, go, monitor, php, pkgcmd, qa, sdk, security, setup, test, updater, vm, workspace Libraries remaining: agentic, build, cache, cli, container, devops, errors, framework, git, i18n, io, log, mcp, process, release, repos Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * refactor(mcp): use pkg/io Medium for sandboxed file operations Replace manual path validation with pkg/io.Medium for all file operations. This delegates security (path traversal, symlink bypass) to the sandboxed local.Medium implementation. Changes: - Add io.NewSandboxed() for creating sandboxed Medium instances - Refactor MCP Service to use io.Medium instead of direct os.* calls - Remove validatePath and resolvePathWithSymlinks functions - Update tests to verify Medium-based behaviour Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix: correct import path and workflow references - Fix pkg/io/io.go import from core-gui to core - Update CI workflows to use internal/cmd/updater path Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix(security): address CodeRabbit review issues for path validation - pkg/io/local: add symlink resolution and boundary-aware containment - Reject absolute paths in sandboxed Medium - Use filepath.EvalSymlinks to prevent symlink bypass attacks - Fix prefix check to prevent /tmp/root matching /tmp/root2 - pkg/mcp: fix resolvePath to validate and return errors - Changed resolvePath from (string) to (string, error) - Update deleteFile, renameFile, listDirectory, fileExists to handle errors - Changed New() to return (*Service, error) instead of *Service - Properly propagate option errors instead of silently discarding - pkg/io: wrap errors with E() helper for consistent context - Copy() and MockMedium.Read() now use coreerr.E() - tests: rename to use _Good/_Bad/_Ugly suffixes per coding guidelines - Fix hardcoded /tmp in TestPath to use t.TempDir() - Add TestResolvePath_Bad_SymlinkTraversal test Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * style: fix gofmt formatting Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * style: fix gofmt formatting across all files Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com>

Configuration
The updater library is highly configurable via the UpdateServiceConfig struct.
UpdateServiceConfig
When creating a new UpdateService, you pass a UpdateServiceConfig struct. Here are the available fields:
| Field | Type | Description |
|---|---|---|
RepoURL |
string |
The URL to the repository for updates. Can be a GitHub repository URL (e.g., https://github.com/owner/repo) or a base URL for a generic HTTP update server. |
Channel |
string |
Specifies the release channel to track (e.g., "stable", "prerelease"). This is only used for GitHub-based updates. |
CheckOnStartup |
StartupCheckMode |
Determines the behavior when the service starts. See Startup Modes below. |
ForceSemVerPrefix |
bool |
Toggles whether to enforce a 'v' prefix on version tags for display and comparison. If true, a 'v' prefix is added if missing. |
ReleaseURLFormat |
string |
A template for constructing the download URL for a release asset. The placeholder {tag} will be replaced with the release tag. |
Startup Modes
The CheckOnStartup field can take one of the following values:
updater.NoCheck: Disables any checks on startup.updater.CheckOnStartup: Checks for updates on startup but does not apply them.updater.CheckAndUpdateOnStartup: Checks for and applies updates on startup.
CLI Flags
If you are using the example CLI provided in cmd/updater, the following flags are available:
--check-update: Check for new updates without applying them.--do-update: Perform an update if available.--channel: Set the update channel (e.g., stable, beta, alpha). If not set, it's determined from the current version tag.--force-semver-prefix: Force 'v' prefix on semver tags (defaulttrue).--release-url-format: A URL format for release assets.--pull-request: Update to a specific pull request (integer ID).
