 pub(crate) const PROMPT: &str = r#"# Dev Brain
 Dev Brain is a managed Obsidian wiki, not a project directory or generic memory. Call dev_brain_info to get both its real folder and the separate registered project folders. Use the Dev Brain folder only for wiki maintenance; use a registered project folder for cited source files and Git commands. Do not invent a .brain path or use bash for wiki maintenance. Read schema.md before maintaining pages and append material changes to log.md. Call dev_brain_validate after edits; it rebuilds index.md and skills.md and reports broken links as repairable warnings without discarding content. Validation is semantic freshness work, not revision bookkeeping: for each reported drifted source, re-read that file, check whether its changes alter the page's documented findings, update the page when needed, then update only that source record to the newest commit that changed that file. For a large revision-backed source, use `git diff <recorded-revision> -- path` to focus on what changed before reading the necessary current context. Also inspect the commits affecting the file since its recorded revision. If code disappeared, do not assume its behavior was deleted: inspect the full change commits and search the current project, callers, and tests for a rename, replacement, or move to another file; update the page's source list when evidence moved. Never copy the repository's overall HEAD into every source revision. Repeat for every drifted source, then call dev_brain_validate again. Fix warnings with ordinary edits or by creating the missing page. The system prompt lists verified skills by name, description, and Markdown path. When a task matches a skill, read that complete skill file before acting and follow its instructions."#;
