Configuration for creating built-in tools.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

file_tracker: Arc<FileTracker>

Shared mtime-based read-before-write tracker.

todo_store: Arc<TodoStore>

Shared todo-list store for the todo tool.

on_question: Option<Arc<OnQuestion>>

Optional callback that resolves structured questions raised by the agent.

workspace: Option<PathBuf>

Optional workspace root; tools restrict path access to descendants when set.

dangerous_tools: bool

Enable dangerous tools (e.g. bash). Default: false.

env_policy: EnvPolicy

Environment variable policy for bash subprocesses.

protected_paths: Vec<PathBuf>

File path patterns to deny access to (e.g., *.env, *.pem).

twitter_credentials: Option<TwitterCredentials>

X/Twitter credentials for the twitter_post builtin tool (per-tenant).

allowlist: Option<Vec<String>>

Optional allowlist of builtin tool names. When Some, only tools whose name appears in this list are returned. When None, all builtins are returned (backward compatible).

path_policy: Option<Arc<CorePathPolicy>>

Application-layer path policy applied to all filesystem builtins (bash, read, write, edit, patch). When set, check_path is called before any I/O, complementing the existing workspace + protected_paths mechanism and the Linux-only Landlock sandbox.

skill_dirs: Vec<PathBuf>

Explicit, highest-precedence skill directories given to the skill tool (each holding <name>/SKILL.md). These are searched before the conventional .opencode/.claude/skills walk and are the SAME dirs the Level-1 catalog is built from, so the catalog never advertises a skill the tool cannot load. Empty (default) = conventional discovery only.

context_recall_store: Option<Arc<ContextRecallStore>>

When present, registers the fetch_full_output / recall_context tools and is shared with the runner for indexing. None = feature off (zero overhead: tools not registered, no indexing).

Trait Implementations

impl Default for BuiltinToolsConfig

fn default() -> Self

Returns the “default value” for a type.
