# Execute PRD Task Execute one PRD task from exploration through tracking updates. ## Code navigation & editing (Serena) If the Serena MCP is available, prefer its symbolic tools over whole-file reads and line-based edits — they are LSP-accurate and token-efficient: - `get_symbols_overview` to grasp a file's structure before reading it; `find_symbol` (by name path, e.g. `Type/method`) to jump straight to a definition. - `find_referencing_symbols` to map every caller before changing a symbol (impact analysis). - `replace_symbol_body`, `insert_after_symbol`, `insert_before_symbol` for precise edits that don't depend on line numbers. Fall back to Grep/Glob + Read/Edit when Serena is unavailable or for plain-text (non-symbol) searches. ## Required Inputs - Task specification markdown. - PRD directory path. - Task file path. - Master tasks file path. - Auto-commit mode. - Optional workflow memory directory path. - Optional shared workflow memory path. - Optional current task memory path. ## Workflow > **Delegation.** Keep this skill's context lean by routing to specialist subagents per the > delegation contract in the `rc` skill (`references/delegation-contract.md`): hand broad or > unfamiliar recon to a `rc-explorer` (cheap/fast, read-only) instead of reading widely > yourself, route version-specific library/API lookups to a `rc-librarian` (cheap, read-only) > instead of guessing from memory, and route architecture/security review or a stubborn debug to > `rc-oracle` (st...
