+# Connectors — Space Engineering Pack
+
+## Shared Python Tools (all skills)
+
+Python tools are in `shared/tools/` and available to all 12 skills. Run with:
+```bash
+python shared/tools/script_name.py subcommand --arg value
+```
+
+All tools output JSON for easy parsing.
+
+## Shared Data Layer
+
+All skills can read from `shared/data/*.json`:
+```python
+# From any tool, access shared data:
+SHARED_DATA = Path(__file__).resolve().parent.parent / "data"
+vehicles = json.load(open(SHARED_DATA / "vehicles.json"))
+```
+
+## Data Freshness
+
+Market data ages. Run the sync checker:
+```bash
+python shared/sync_data.py --check    # Check if data is stale
+python shared/sync_data.py --force    # Force refresh via web search
+```
+
+Physics constants (`constants.py`) never expire.
+
+## Cross-Skill Integration
+
+Skills reference each other when relevant:
+- Propulsion → calls orbital-mechanics for transfer delta-v
+- Mission-architect → aggregates budgets from all subsystem skills
+- Satellite-comms → uses orbital-mechanics for coverage geometry
+
+## External Tool Integration
+
+When available, these Claude Code skills enhance output:
+| Skill | Enhancement |
+|-------|------------|
+| `xlsx` | Export budgets as Excel spreadsheets with formulas |
+| `pptx` | Generate mission review presentations |
+| `data` | Visualize trade study results |
+| `pdf` | Create formal mission reports |
