Tools & Capabilities Breakdown

Agent Lsp Tools (65)

activate_skill

Activate phase enforcement for a skill workflow. Once active, tool calls are checked against the skill's phase permissions. Phases advance automatically as you call tools from later phases. Use this at the start of a skill workflow to enable safety guardrails that prevent out-of-order operations (e.g., applying edits before completing blast-radius analysis).

add_workspace_folder

Add a directory to the LSP workspace, enabling cross-repo references, definitions, and diagnostics. Useful when working across a library and its consumers — after adding the consumer repo, find_references on a library function returns call sites in both repos. Requires start_lsp to have been called first. Language servers that support multi-root workspaces (gopls, rust-analyzer, typescript-language-server) will re-index the new folder automatically.

apply_edit

Apply an edit to a file. Two modes: (1) WorkspaceEdit mode: pass workspace_edit with positional changes returned by rename_symbol or format_document; (2) Text-match mode: pass file_path + old_text + new_text to find and replace text. For full function/method body replacements, consider replace_symbol_body which resolves by symbol name instead of text matching. Always call preview_edit first to verify the edit is safe.
