## Summary by cubic
Streamlined efficiency guidelines and action docs to make multi‑action
steps safer and clearer. Fixed URL detection by stripping emails before
matching, and improved scroll guidance to prefer larger jumps and omit
index for full‑page scrolling.
- **Bug Fixes**
- Remove emails from task text before URL matching to prevent false
positives.
- **Refactors**
- Simplified efficiency_guidelines in all prompts; added clear do/don’t
for chaining and updated recommended combos (including scroll +
extract).
- Clarified click_element_by_index and input_text descriptions to only
allow indices from the current browser_state.
- Updated scroll action docs to favor high num_pages (e.g., 10) and to
omit index when scrolling the entire page.

## Summary by cubic
Improves the extract_structured_data tool to return cleaner, more
accurate results by normalizing page markdown, enforcing input limits,
and using a clearer system+user prompt. This makes extractions more
consistent and reduces noisy or invented outputs.
- **Refactors**
- Normalizes markdown: removes artifacts, demarkdowns inline links,
compresses excessive newlines, and trims whitespace.
- Enforces size limits: truncates content at MAX_CHAR_LIMIT and
annotates when truncated.
- Uses structured prompting: sends SystemMessage + UserMessage with
strict rules (page-only facts, list all items, non-conversational
output, note if data is missing).
- Clarifies tool usage: updated action description to discourage using
it for interactive elements and to gate link extraction via
extract_links.
- Simplifies memory handling: only stores small results
(MAX_MEMORY_LENGTH).

## Summary by cubic
Standardized the max_steps description across the server schema and docs
with consistent wording and punctuation. Cleaned up the real-browser
guide by merging duplicate notes and clarifying that we use DuckDuckGo
because Google blocks this approach.

fixes os related font error at gif creation
<!-- This is an auto-generated description by cubic. -->
---
## Summary by cubic
Fixes GIF creation crashes on some OSes by adding a safe fallback when
loading fonts. If loading a TrueType font fails, we now use the existing
regular font.
- **Bug Fixes**
- Catch OSError/AttributeError from ImageFont.truetype and fall back to
regular_font.
- Prevents failures when regular_font has no .path or the font cannot be
loaded.

## Summary by cubic
Introduce BrowserError with short- and long-term memory to carry
structured context from browser events to the LLM, replacing brittle
string parsing. Improves guidance after failures (clicks, dropdowns,
uploads) and makes errors more actionable.
- **New Features**
- Added BrowserError with short_term_memory (one-shot guidance) and
long_term_memory (persistent context).
- Dropdown actions return structured memory; on selection failure,
return available options for the LLM to choose from.
- Tools map BrowserError to ActionResult via handle_browser_error,
setting include_extracted_content_only_once when needed.
- **Refactors**
- Replaced <llm_error_msg>-based parsing with structured errors across
click, input, upload, navigation, tabs, scroll, and send keys.
- Standardized error messages and improved timeout handling; registry
now surfaces TimeoutError as a clear RuntimeError.
- Safer file upload validation; common invalid path and missing element
cases return ActionResult instead of crashing.
- Removed automatic get_dropdown_options during click failures to avoid
hidden side effects.
- Updated dependency: bubus >= 1.5.6.

## Summary by cubic
Add full support for <frame> elements alongside <iframe> so framed
content is detected, indexed, and serialized correctly. Also cleans up
SimplifiedNode JSON to avoid duplicated children and large payloads.
- **Bug Fixes**
- Handle FRAME everywhere IFRAME is handled: interactive detection,
visibility/offset, and serialization (adds |FRAME| marker).
- Traverse frame content via content_document.children_nodes and include
nodes when appropriate (fixes include check).
- Recursively remove children_nodes and shadow_roots from original_node
JSON, including nested content_document.

Auto-generated PR for: make highlights sync
<!-- This is an auto-generated description by cubic. -->
---
## Summary by cubic
Switches highlight rendering from async parallel to synchronous
sequential to avoid PIL ImageDraw thread-safety issues. This stabilizes
overlays and prevents intermittent rendering glitches.
- Bug Fixes
- Process elements sequentially in create_highlighted_screenshot; make
process_element_highlight synchronous.
- Remove asyncio usage and related code; update docstrings accordingly.
