+# Agent Instructions - docker-seafile-client
+
+Docker container for Seafile CLI client with automatic retry logic for server outages.
+
+## Quick Commands
+
+### Build & Test Locally
+```bash
+# Build image
+docker build -t snegov/seafile-client:test .
+
+# Test locally with docker-compose
+docker compose build
+docker compose up
+
+# Check logs
+docker compose logs -f
+```
+
+### Build & Deploy Test Image to Docker Hub
+```bash
+# Build fresh image without cache
+docker build --no-cache -t snegov/seafile-client:test .
+
+# Push to Docker Hub (requires login)
+docker push snegov/seafile-client:test
+```
+
+Deploying to hosts is documented in `CLAUDE.local.md` (private, not in the
+repo).
+
+### Release New Version
+```bash
+# Create tag; pushing it to GitHub runs the Docker Hub publish workflow
+git tag 0.0.X
+git push gh 0.0.X
+
+# Docker Hub will automatically build snegov/seafile-client:latest and snegov/seafile-client:0.0.X
+```
+
+### Syntax Check
+```bash
+python3 -m py_compile dsc/client.py
+python3 -m py_compile start.py
+```
+
+## Project Structure
+
+```
+dsc/
+  client.py       - Main SeafileClient class
+  const.py        - Constants
+  misc.py         - Helper functions
+  __init__.py     - Package init
+start.py          - Container entrypoint
+Dockerfile        - Image definition
+docker-compose.yml - Local testing setup
+requirements.txt  - Python dependencies
+```
+
+## Architecture Notes
+
+### HTTP Retry Strategy
+- 30 retry attempts with exponential backoff (2s base, 60s max)
+- Retries on 500, 502, 503, 504 status codes
+- Prevents container crash-loop during server outages
+- urllib3 debug logging shows retry attempts
+
+### Session Management
+- Single `requests.Session` per client instance
+- Retry logic configured via `HTTPAdapter` + `Retry`
+- Token cached in `self.__token` (fetched on first use)
+
+### Server URL Handling
+- Assumes HTTPS unless `http://` explicitly specified
+- No initial connection test (fails fast on first API call)
+
+### Library Status Monitoring
+- Dynamic column width (max 30 chars) for clean output
+- Only logs status changes (not every poll)
+- Handles long library names without breaking alignment
+
+## Testing
+
+No formal test suite yet. Manual testing via:
+1. Build image
+2. Run with docker-compose
+3. Monitor logs for expected behavior
+4. Test with server down (should retry, not crash)
+
+## Deployment
+
+- Production: `snegov/seafile-client:latest` (auto-built from tags)
+- Testing: `snegov/seafile-client:test` (manual push)
+
+## Common Issues
+
+**Container crash-loops on 502**: Retry logic should handle this (check urllib3 logs).
+
+**No retry logs visible**: Ensure urllib3 logger is set to DEBUG and propagate=True.
+
+**Wrong image deployed**: Clear old image with `docker rmi` before pulling fresh one.
