Analyze video files to understand their technical properties, identify quality issues, and recommend appropriate next steps (remux, reencode, or leave unchanged).
Requires mediainfo CLI tool. Install via:
brew install mediainfoapt install mediainfo or equivalentRun MediaInfo to get comprehensive file information:
mediainfo --Full "/path/to/video.mkv"
For quick summary:
mediainfo "/path/to/video.mkv"
Extract and report separately:
Container format (file extension): mkv, mp4, webm, avi, mov, m2ts
Video codec (actual encoding): H.264 (AVC), H.265 (HEVC), VP9, AV1, ProRes
Key MediaInfo fields:
Format under "General" section = containerFormat under "Video" section = codecExamine these fields in MediaInfo's Video section:
| Parameter | Expected Value | Problem Indicator |
|---|---|---|
| Color primaries | BT.709 | BT.601 on HD content |
| Matrix coefficients | BT.709 | BT.601 on HD content |
| Transfer characteristics | BT.709 | Mismatched values |
| Color range | Limited | "Full" on broadcast content |
| Chroma subsampling | 4:2:0 | Unusual values |
Red flags:
For detailed color space information, consult ${CLAUDE_PLUGIN_ROOT}/references/color-space.md.
Check MediaInfo for these warning signs:
Encoding quality indicators:
Encoded_Library: Look for x264/x265 (good) vs NVENC/QuickSync (lower quality for archival)Writing application: Identify source (ffmpeg, Handbrake, etc.)Bit rate mode: VBR preferred over CBR for qualitySuspicious characteristics:
Content red flags:
Based on findings, recommend one of:
Leave unchanged when:
Remux only when:
Reencode required when:
Avoid/warn when:
| If user says... | They probably mean... | Actual operation |
|---|---|---|
| "Convert mkv to mp4" | Change container | Remux (fast, lossless) |
| "Compress this video" | Reduce file size | Reencode (slow, quality loss) |
| "Make it H.265" | Change codec | Reencode (slow, quality loss) |
| "Fix the colors" | Depends on issue | Retag (fast) or reencode (slow) |

Trigger when user wants a second opinion on code changes ("have agy review my changes", "get code review from Google Antigravity", "review this diff with agy"), or as a final check before committing. Replaces the deprecated gemini-cli diff-review workflow.
Get Google Antigravity's (`agy`) review of Claude's implementation plans. Trigger when user wants a second opinion on a plan ("have agy review this plan", "get a second opinion from Google Antigravity", "critique this plan with agy"), or after Claude creates a plan file that needs validation before implementation. Replaces the deprecated gemini-cli plan-review workflow.
Real-time web research using Google Search via Google's Antigravity (`agy`) CLI — the replacement for the deprecated `gemini-cli`. Trigger when user needs current information ("search with agy", "search with Google Antigravity", "find current info about X with agy", "what's the latest on Y"), library/API research, security vulnerability lookups, or comparisons requiring recent data.
Deep architectural analysis of the current workspace using Google Antigravity (`agy`). Trigger when the user needs an architecture overview ("analyze this codebase with agy", "map dependencies with Google Antigravity"), is onboarding to unfamiliar code, exploring legacy systems, or hunting technical debt. Replaces the deprecated gemini-cli `codebase_investigator` workflow.
Codebase analysis via the Codex MCP server with a read-only sandbox. Trigger when user needs architecture overview ("analyze this codebase with Codex", "have Codex map dependencies"), onboarding to unfamiliar code, understanding legacy systems, or identifying technical debt.
Get Codex's code review of git changes via the Codex MCP server. Trigger when user wants a second opinion on code changes ("have Codex review my changes", "get code review from Codex", "review this diff with Codex"), or as a final check before committing.
