Options for build_system_prompt.

Mirrors TypeScript BuildSystemPromptOptions. Field names are snake_case; wire callers join multi-value append sources with "\n\n" before setting Self::append.

Fields

custom_prompt: Option<String>

Custom system prompt body (replaces the default identity/tools/guidelines/docs block).

Empty and None both take the default path (matches JS truthiness on customPrompt).

selected_tools: Option<Vec<String>>

Tools considered active for snippets, guidelines, and the skills gate.

When None, defaults to read, bash, edit, write. An empty Vec means no tools.

tool_snippets: Option<HashMap<String, String>>

One-line tool snippets keyed by tool name. A tool appears under Available tools only when its snippet is present and non-empty.

prompt_guidelines: Option<Vec<String>>

Extra guideline bullets (trimmed, de-duplicated, first-add wins).

append: Option<String>

Text appended after the base/custom body (before project context).

Empty and None omit the append section.

cwd: String

Working directory (required). Backslashes are normalized to / in the final cwd line only.

context_files: Option<Vec<AgentsFile>>

Pre-loaded project context files (AGENTS.md / CLAUDE.md).

skills: Option<Vec<Skill>>

Pre-loaded skills (formatted via format_skills_for_prompt).
