+# OpenClaw Macro System — Agent Harness SOP
+
+## What Is This?
+
+**OpenClaw Macro System** is a layered CLI that turns valuable GUI workflows into
+parameterized, agent-callable macros. The agent sends one command:
+
+```bash
+cli-anything-openclaw macro run export_png --param output=/tmp/out.png --json
+```
+
+The system handles everything else: parameter validation, precondition checks,
+backend selection, step execution, postcondition verification, and structured
+result output. The agent never touches the GUI directly.
+
+## Architecture
+
+```
+Agent
+  └─▶  cli-anything-openclaw macro run <name> --param k=v --json   (L6: CLI)
+             │
+        MacroRuntime                                                  (L5)
+             │  1. Validate params against MacroDefinition schema
+             │  2. Check preconditions (file_exists, process_running, …)
+             │  3. For each step:
+             │       RoutingEngine → select backend by priority       (L3)
+             │       Backend.execute(step, resolved_params)           (L2)
+             │  4. Check postconditions
+             │  5. Collect declared outputs
+             │  6. Record telemetry in ExecutionSession
+             └─▶  { success, output, error, telemetry }
+```
+
+## Layer Mapping
+
+| Layer | Name | Implementation |
+|-------|------|---------------|
+| L7 | Agent Task Interface | Caller (OpenClaw or any agent) |
+| L6 | Unified CLI Entry | `openclaw_cli.py` — Click CLI |
+| L5 | Macro Execution Runtime | `core/runtime.py` |
+| L4 | Parameterized Macro Model | `core/macro_model.py` + `macro_definitions/*.yaml` |
+| L3 | Backend Routing Engine | `core/routing.py` |
+| L2 | Execution Backends | `backends/` (5 backends) |
+| L1 | Target Application | Any GUI-first or closed-source app |
+
+## Execution Backends
+
+| Backend | Priority | Trigger | Use case |
+|---------|----------|---------|----------|
+| `native_api` | 100 | `backend: native_api` | subprocess / shell commands |
+| `gui_macro` | 80 | `backend: gui_macro` | precompiled coordinate replay (pyautogui) |
+| `file_transform` | 70 | `backend: file_transform` | XML, JSON, text file editing |
+| `semantic_ui` | 50 | `backend: semantic_ui` | accessibility API + keyboard (xdotool) |
+| `recovery` | 10 | `backend: recovery` | retry + fallback orchestration |
+
+The RoutingEngine respects the step's explicit `backend:` field; if that backend
+is unavailable it walks down the priority list.
+
+## Macro Definition Format
+
+Macros live in `cli_anything/openclaw/macro_definitions/` as YAML files:
+
+```yaml
+name: export_png
+version: "1.0"
+description: Export the active diagram to PNG.
+
+parameters:
+  output:
+    type: string
+    required: true
+    example: /tmp/diagram.png
+
+preconditions:
+  - process_running: draw.io
+  - file_exists: /path/to/input.drawio
+
+steps:
+  - id: export
+    backend: native_api
+    action: run_command
+    params:
+      command: [draw.io, --export, --output, "${output}", input.drawio]
+    timeout_ms: 30000
+    on_failure: fail     # or: skip | continue
+
+postconditions:
+  - file_exists: ${output}
+  - file_size_gt:
+      - ${output}
+      - 100
+
+outputs:
+  - name: exported_file
+    path: ${output}
+
+agent_hints:
+  danger_level: safe
+  side_effects: [creates_file]
+  reversible: true
+```
+
+### Supported Condition Types
+
+| Type | Args | Checks |
+|------|------|--------|
+| `file_exists` | path | `os.path.exists(path)` |
+| `file_size_gt` | [path, min_bytes] | `os.stat(path).st_size > min_bytes` |
+| `process_running` | name | `pgrep -x name` or psutil |
+| `env_var` | name | `name in os.environ` |
+| `always` | true/false | constant pass/fail |

+
+## Installation
+
+```bash
+cd openclaw-skill/agent-harness
+pip install -e .
+```
+
+**Runtime dependencies:** Python 3.10+, PyYAML, click, prompt-toolkit.
+
+**Optional (for specific backends):**
+- `xdotool` — semantic_ui backend on Linux
+- `pyautogui` — gui_macro backend
+- `psutil` — richer process_running checks
+
+## Running Tests
+
+```bash
+cd openclaw-skill/agent-harness
+python3 -m pytest cli_anything/openclaw/tests/ -v -s
+# 64 passed
+```
+
+## Key Design Decisions
+
+**Why YAML macros, not Python?** YAML macros are readable by agents without
+running code, inspectable via `macro info`, and editable without touching the
+harness source.
+
+**Why 5 backends?** Real GUI applications expose many different control
+surfaces. The routing engine picks the most reliable one available — the agent
+doesn't need to know which one ran.
+
+**Why preconditions and postconditions?** Agents operate in environments where
+state is uncertain. Failing loudly before execution (preconditions) and
+verifying after (postconditions) catches problems the agent can act on.
+
+**Why `on_failure: skip | continue`?** Some macro steps are best-effort (e.g.,
+confirming a dialog that may or may not appear). Skipping lets the macro
+continue to the real work.
