+**manual_slop** is a local GUI tool for manually curating and sending context to AI APIs. It aggregates files, screenshots, and discussion history into a structured markdown file and sends it to a chosen AI provider with a user-written message.
+
+**Stack:**
+- `dearpygui` - GUI with docking/floating/resizable panels
+- `google-genai` - Gemini API
+- `anthropic` - Anthropic API
+- `tomli-w` - TOML writing
+- `uv` - package/env management
+
+**Files:**
+- `gui.py` - main GUI, `App` class, all panels, all callbacks
+- `ai_client.py` - unified provider wrapper, model listing, session management, send
+- `aggregate.py` - reads config, collects files/screenshots/discussion, writes numbered `.md` files to `output_dir/md_gen/`
+- `config.toml` - namespace, output_dir, files paths+base_dir, screenshots paths+base_dir, discussion history array, ai provider+model
+- `credentials.toml` - gemini api_key, anthropic api_key
+
+**GUI Panels:**
+- **Config** - namespace, output dir, save
+- **Files** - base_dir, scrollable path list with remove, add file(s), add wildcard
+- **Screenshots** - base_dir, scrollable path list with remove, add screenshot(s)
+- **Discussion History** - multiline text box, `---` as separator between excerpts, save splits on `---` back into toml array
+- **Provider** - provider combo (gemini/anthropic), model listbox populated from API, fetch models button, status line
+- **Message** - multiline input, Gen+Send button, MD Only button, Reset session button
+- **Response** - readonly multiline displaying last AI response
+
+**Data flow:**
+1. GUI edits are held in `App` state lists (`self.files`, `self.screenshots`, `self.history`) and dpg widget values
+2. `_flush_to_config()` pulls all widget values into `self.config` dict
+3. `_do_generate()` calls `_flush_to_config()`, saves `config.toml`, calls `aggregate.run(config)` which writes the md and returns `(markdown_str, path)`
+4. `cb_generate_send()` calls `_do_generate()` then threads a call to `ai_client.send(md, message)`
+5. `ai_client.send()` prepends the md as a `<context>` block to the user message and sends via the active provider chat session
+6. Sessions are stateful within a run (chat history maintained), `Reset` clears them
+
+**Config persistence:**
+- Every send and save writes `config.toml` with current state including selected provider and model under `[ai]`
+- Discussion history is stored as a TOML array of strings in `[discussion] history`
+- File and screenshot paths are stored as TOML arrays, support absolute paths, relative paths from base_dir, and `**/*` wildcards
+
+**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
