+> **Update 2026-06-04 — prompts externalized.** All prose prompts now live as
+> editable files under `~/.todo-app/prompts/`, each seeded from a bundled default in
+> `src/ClaudeDo.Data/PromptFiles.cs` (read via `ReadOrDefault` / `Render`, which
+> substitutes only named `{tokens}`):
+> `system.md`, `planning-system.md`, `planning-initial.md` (`{title}`/`{description}`),
+> `retry.md`, `daily-prep.md` (`{date}`/`{maxTasks}`), `weekly-report.md`
+> (`{start}`/`{end}`; German output). The old `agent.md` and `planning.md` are
+> retired — `system.md` is the single appended system prompt (the agent/manual split
+> is gone), and the planning system prompt is `planning-system.md`. Daily-prep and
+> retry prompts are now English; retry leans on the resumed session and appends the
+> captured stderr only when it's a real error (not the generic "exited with code N").
+> The system prompt instructs the agent to emit `CLAUDEDO_BLOCKED: <reason>` on its
+> own line for any true blocker; `StreamAnalyzer` collects every marker, strips them
+> from the result, and `TaskRunner` folds them into the review result as a
+> "⚠ Roadblocks" section. All six prompt files are editable from Settings → Files.
