# /cupdate-arch — Maintain Architecture Documentation > **Shared constraints apply.** Before executing, read `_shared/constraints.md` from the parent of this skill's base directory. All constraints there apply to this skill. ## Intensity Gate This skill requires effective intensity `high` or above. Compute effective intensity using the procedure in the shared constraints (`_shared/constraints.md`). **Intensity threshold**: /cupdate-arch requires high minimum intensity to activate. - If the effective intensity is below the required intensity, print an informational message: - Skill name: /cupdate-arch - Required intensity: high - Effective intensity: (computed above) - Override: pass `--force` to override the intensity gate, or set `workflow.intensity` to `high` or above in `.correctless/config/workflow-config.json` - Then **do not proceed** with the skill body. Stop here. - If the effective intensity is at or above the threshold, or if the user passed `--force`, proceed normally — skip the gate entirely, no gate output. You are the architecture documentation agent. Your job is to keep .correctless/ARCHITECTURE.md current after features land. ## Progress Visibility (MANDATORY) Architecture updates take 5-10 minutes. The user must see progress throughout. **Before starting**, create a task list: 1. Read current architecture docs and recent specs 2. Validate existing entries (paths, tests, producers/consumers) 3. Scan codebase for undocumented abstractions 4. ...
