+# Continuity Doctor — Specification
+
+## Purpose
+
+The continuity doctor is a diagnostic tool that checks whether the
+memory-continuity protocol is being followed correctly in a workspace.
+It reports problems but does **not** auto-fix them.
+
+## Design philosophy
+
+- **Diagnose, don't repair.** Automated repair of state files is dangerous
+  because incorrect "fixes" can overwrite valid state. The doctor flags
+  issues for human or agent review.
+- **Fast and offline.** No API calls, no database queries. Reads files only.
+- **Exit codes matter.** 0 = healthy, 1 = warnings found, 2 = critical issues.
+
+## Checks performed
+
+### 1. Existence check
+- Does `memory/CURRENT_STATE.md` exist?
+- Severity: CRITICAL if missing (no recovery possible)
+
+### 2. Staleness check
+- When was `CURRENT_STATE.md` last modified?
+- If older than the most recent session transcript, it is stale.
+- Severity: WARNING
+
+### 3. Template compliance
+- Does the file contain all mandatory sections?
+  (Objective, Current Step, Key Decisions, Next Action, Blockers, Unsurfaced Results)
+- Are any sections still showing placeholder text like `[One sentence: ...]`?
+- Severity: WARNING for missing sections, INFO for placeholder text
+
+### 4. Unsurfaced results
+- Is the `Unsurfaced Results` section non-empty?
+- If yes, someone needs to review those results.
+- Severity: WARNING
+
+### 5. Archive consistency
+- Are there files in `memory/session_archive/` ?
+- Does the newest archive have a different Objective than CURRENT_STATE.md?
+  (This is expected if the user switched tasks, but worth flagging.)
+- Severity: INFO
+
+### 6. Conflict detection (optional, if tasks file exists)
+- If a `tasks.md` or `openspec/` directory exists, does the Objective in
+  CURRENT_STATE.md align with any active task?
+- Severity: INFO (alignment is nice-to-have, not mandatory)
+
+## Output format
+
+```
+[CRITICAL] memory/CURRENT_STATE.md does not exist
+[WARNING]  CURRENT_STATE.md is stale (last modified 2h ago, session ran 30m ago)
+[WARNING]  Unsurfaced Results section is not empty — review needed
+[INFO]     Archive objective differs from current objective (task switch?)
+[OK]       Template compliance: all sections present
+```
+
+## Future extensions (not yet implemented)
+
+- Multi-workspace scan (check all sub-agent workspaces)
+- JSON output mode for programmatic consumption
+- Integration with OpenClaw cron for scheduled health checks
