 - **FSM-driven execution** — explicit `WAIT` / `TOOL` / `TRET` / `SUPERVISE` / `DONE` / `ERRS` / `ABRT` states. Completion supervision nudges the model when it stops early, while failed tool calls are sanitized so they never strand the agent. Transient API failures (`429` / `5xx`) retry with exponential backoff and jitter. Auth-expired status codes (configurable via `AUTH_REFRESH_STATUS_CODES` in `config.py`; defaults to `[401, 502]`) trigger automatic API key re-read from config/env — some API gateways return `502` instead of `401` when the backend auth token has expired. Note: codes in this list are treated as auth-expired exclusively and will not be retried with backoff, so only include codes that are unambiguously auth-related in your environment.
 - **Context management** — CJK-aware token estimation, per-model context windows, and automatic compaction at 70% usage.
-- **Image & text attachments** — attach an image or a text file with `@path` in your message (e.g. `@screenshot.png`, `@README.md`): images (PNG/JPEG/GIF/WebP, up to 20 MB, magic-byte validated) become multimodal `image_url` parts, text files are inlined as text. Only images and text files are supported as input. Paste an image from the clipboard to attach it too (macOS `pngpaste`, Wayland `wl-paste`, X11 `xclip`, Windows PowerShell — no extra dependencies).

 - **Coding tools** — `Agent`, `TodoWrite`, `Glob`, `Grep`, `Read`, `Insert`, `Edit` (including unified diffs), `Write`, `Mkdir`, `Bash`, `Skill`, `Question`, `LSP`, and `PlanExit`. Synchronous tools execute sequentially, but a round made up entirely of read-only tools (`Read`, `Glob`, `Grep`, `Skill`, `LSP`) is dispatched concurrently via a bounded thread pool; asynchronous tools such as `Bash` and `Agent` can run concurrently as well. Results are always delivered in the model's emitted order.
 - **Plan / Build modes** — plan mode is read-only except for the per-session plan file.
 - **Persistent sessions** — sessions are automatically saved after every response to `~/.local/share/python-agent-harness/sessions/`, with LLM-generated titles and support for `/restore --latest` and `/sessions`.
