 - Before any script runs, `gui.py` shows a modal `ConfirmDialog` on the main thread; the background send thread blocks on a `threading.Event` until the user clicks Approve or Reject
 - The dialog displays `base_dir`, shows the script in an editable text box (allowing last-second tweaks), and has Approve & Run / Reject buttons
 - On approval the (possibly edited) script is passed to `shell_runner.run_powershell()` which prepends `Set-Location -LiteralPath '<base_dir>'` and runs it via `powershell -NoProfile -NonInteractive -Command`
-- Every script (original, before Set-Location is prepended) is saved to ./scripts/generated/ai_<timestamp>.ps1 before execution; the saved path appears in the tool result
 - stdout, stderr, and exit code are returned to the AI as the tool result
 - Rejections return `"USER REJECTED: command was not executed"` to the AI
 - All tool calls (script + result/rejection) are appended to `_tool_log` and displayed in the Tool Calls panel
 
+**Comms Log (ai_client.py):**
+- `_comms_log: list[dict]` accumulates every API interaction during a session
+- `_append_comms(direction, kind, payload)` called at each boundary: OUT/request before sending, IN/response after each model reply, OUT/tool_call before executing, IN/tool_result after executing, OUT/tool_result_send when returning results to the model
+- Entry fields: `ts` (HH:MM:SS), `direction` (OUT/IN), `kind`, `provider`, `model`, `payload` (dict)
+- Anthropic responses also include `usage` (input_tokens/output_tokens) and `stop_reason` in payload
+- `get_comms_log()` returns a snapshot; `clear_comms_log()` empties it
+- `comms_log_callback` (injected by gui.py) is called from the background thread with each new entry; gui queues entries in `_pending_comms` (lock-protected) and flushes them to the DPG panel each render frame
+- `MAX_FIELD_CHARS = 400` in ai_client is the threshold used for the clamp decision in the UI (`COMMS_CLAMP_CHARS = 300` in gui.py governs the display cutoff)
+
+**Comms History panel rendering:**
+- Each entry shows: index, timestamp, direction (colour-coded blue=OUT / green=IN), kind (colour-coded), provider/model
+- Payload fields rendered below the header; fields in `_HEAVY_KEYS` (`message`, `text`, `script`, `output`, `content`) that exceed `COMMS_CLAMP_CHARS` are shown in an 80px tall readonly scrollable `input_text` box instead of a plain `add_text`
+- Colour legend row at the top of the panel
+- Status line (formerly in Provider panel) moved to top of Comms History panel
+- Reset session also clears the comms log and panel; Clear button in Comms History clears only the comms log

 **Known extension points:**
 - Add more providers by adding a section to `credentials.toml`, a `_list_*` and `_send_*` function in `ai_client.py`, and the provider name to the `PROVIDERS` list in `gui.py`
 - System prompt support could be added as a field in `config.toml` and passed in `ai_client.send()`
 - Discussion history excerpts could be individually toggleable for inclusion in the generated md
 - `MAX_TOOL_ROUNDS` in `ai_client.py` caps agentic loops at 5 rounds; adjustable
