feat: Add Manim toolkit and AgentOS examples#7554
Open
Conversation
Introduce a Manim toolkit and example agents for rendering Manim CE scenes and attaching MP4s to run responses. Adds libs/agno/agno/tools/manim.py (ManimTools with render_scene/arender_scene, quality presets, error handling, and list_rendered_videos), a CLI demo cookbook/91_tools/manim_tools/manim_tools.py, an AgentOS wrapper cookbook/91_tools/manim_tools/manim_agentos.py, plus README and TEST_LOG. Videos are read into memory as agno.media.Video (base64-inlined at serialization); on-disk artifacts are placed under tmp/ for easy cleanup.

There was a problem hiding this comment.
this should rather be a util function within the sdk.

Please add some tests and link a docs PR |
Add size and duration safety bounds for Manim renders: introduce max_inline_bytes (25 MB default) and max_duration_seconds (120s default), increase default timeout to 900s, and validate their values. Use ffprobe to probe output duration and reject overlong renders; inline small mp4s as Video(content=...) and persist/return large renders as Video(filepath=...). Quiet manim subprocess output by adding -v WARNING and --progress_bar none. Update README to document delivery and safety bounds, adjust example script, and add comprehensive unit tests (libs/agno/tests/unit/tools/test_manim.py) covering success, errors, delivery modes, and probes.
Add robust video persistence and update test log. - Implement save_video_to_disk that handles Video(content), Video(filepath) and remote content (via get_content_bytes), copying or decoding as appropriate; add backwards-compatible alias save_base64_video_to_disk. Import shutil for file copies. - Update CLI/agent scripts to detect delivery mode (inline/filepath/url), print delivery info and saved file sizes, and switch to the new save_video_to_disk API. - Remove hardcoded timeout_seconds=180 from Agent tool instantiations to rely on defaults. - Expand TEST_LOG.md with unit test results (16/16 pass) and mark end-to-end / voice / AgentOS checks as pending. These changes ensure large renders that are returned as filepaths are handled correctly, preserve backward compatibility, and improve developer visibility into test and run outputs.
