+# Agent Tasks
+
+Bounded, approval-aware prompts for agents working in `tegwick-control`.
+
+## When to use
+
+Create an agent task when:
+
+- the work stays inside this repository (drafting, structuring, summarizing);
+- boundaries and forbidden changes are clear;
+- human approval gates are explicit;
+- the task is ready to hand to an agent without further triage.
+
+Do **not** use agent tasks for:
+
+- implementation work in other repos (prepare the prompt here, execute elsewhere);
+- legal, tax, or financial conclusions;
+- converting options into commitments without approval.
+
+## Layout
+
+```text
+agent-tasks/
+├── README.md                          this file
+├── <area>-<action>-<subject>.md       ready agent prompts
+└── archive/                           completed or superseded tasks
+```
+
+Flat layout by default. Move finished tasks to `archive/` during review.

+
+Examples:
+
+- `binky-surface-critical-path.md`
+- `tegwick-review-area-cards.md`
