Changelog

All notable changes to /watch are documented here.

[0.3.0] — Unreleased

Added

• Managed, optional WhisperX 3.8.6 setup with uv, a separate Python 3.12 environment, cache warm-up, recoverable installation state, and local CPU transcription. Default model: small, int8, batch 8; language and timeout are configurable. Local failures never select a cloud provider.
• One-time fallback selection in the skill wizard: WhisperX, Groq, OpenAI, or captions only. Existing installations retain the auto cloud-key preference.
• Original-language caption selection and provenance, --sub-lang, and explicit cookie-file/browser options shared across downloader stages.
• Reports for unavailable modalities, no speech, and missing cloud-transcription intervals. Offline dependency diagnostics and a cross-platform CI gate for release publication.

Fixed

• Uniform sampling now spans the actual capped range and labels selected source frames with their real timestamps, including fractional seeks and cue frames.
• FFmpeg sync-option capability detection, empty keyframe-window fallback, RGB thumbnail deduplication, and actionable probe/launch errors.
• UTF-8 output and subprocess decoding, BOM-aware shared config parsing, provider-key pairing, atomic config updates, keyless readiness, and advisory setup hooks.
• Bounded caption downloads respect watch-owned output templates while retaining intentional yt-dlp configuration. Fresh run directories and completed final-path validation prevent stale/partial media reuse.
• WebVTT optional-hour timestamps, entities, cue/block parsing, and overlap-scoped deduplication preserve independent repeated speech.
• Full-track caption availability is checked before focus filtering; successful captions survive media/probe failures.
• Conservative 24,000,000-byte cloud upload budgets, actual chunk/multipart size checks, and explicit partial/no-speech metadata.

Changed

• First-success installation documentation separates media tools from optional speech backends and describes host/network limitations.
• User-provided output directories now contain a disposable run child; cleanup preserves the parent and source files.
• The base runtime remains standard-library-only; local model environments and caches live outside the self-contained skill folder.

[0.2.0] — 2026-06-29

Added

• --detail dial with four modes — transcript (captions only, no frames), efficient (fast keyframe pass, cap 50), balanced (scene-aware, cap 100, default), and token-burner (scene-aware, uncapped). Set the default with WATCH_DETAIL in ~/.config/watch/.env.
• Frame deduplication (default on; --no-dedup to disable). Before the budget cap, a pass downscales each frame to a 16×16 grayscale thumbnail and drops frames whose mean per-pixel difference from the last kept frame is within threshold — so the budget goes to distinct content instead of held slides and static recordings. The Frames report line shows how many near-duplicates were dropped.
• Whisper auto-chunking. Audio over the 25 MB upload cap is split into evenly sized chunks, transcribed per chunk, with segment timestamps shifted back into source time. Partial failures are tolerated — transcription only fails if every chunk fails, so length alone no longer breaks it.
• --timestamps T1,T2,… — grab a frame at each absolute timestamp; reserved against the cap, and the only frames produced under --detail transcript.
• --no-whisper — disable speech fallback while retaining native captions.
• pytest suite covering config, dedup, download, fixtures, frames, setup, timestamps, watch, and whisper (no network; ffmpeg-synthesized clips).

Changed

• Restructured into a self-contained skills/watch/ package so SKILL.md and its scripts/ runtime are siblings in one folder. This fixes installs on Codex, Cursor, Copilot, and other Agent Skills hosts: npx skills add now copies the skill as a working unit instead of grabbing the root SKILL.md without its scripts.
• Harness-agnostic path resolution — SKILL.md resolves $SKILL_DIR from where it was Read instead of the Claude-Code-only ${CLAUDE_SKILL_DIR}, so script calls work on every host.
• /watch is now derived from SKILL.md frontmatter; the separate commands/watch.md wrapper was dropped to avoid a duplicate slash command.
• balanced now full-decodes to detect every scene cut across the whole video. The previous early-exit was faster but kept only the first cuts and dropped the tail of long videos.
• token-burner is exempt from the long-video "sparse scan" warning, since it keeps every scene-change frame.
• --max-frames is now an override on top of each mode's default cap, rather than a fixed default of 80.

Fixed

• Non-Claude installs (npx skills add) were dead on arrival — the installer copied SKILL.md without the scripts/ it shells out to. The self-contained package layout resolves this.

Removed

• V2_PLAN.md and V2_CONCERNS.md planning docs.

[0.1.3] — 2026-05-09

Fixed

• Windows: video.info.json is read as UTF-8 (#4). Previously Path.read_text() defaulted to cp1252 on Windows and crashed on yt-dlp's UTF-8 output, silently dropping Title/Uploader from the report. Same fix applied to .env reads/writes in whisper.py and setup.py.
• download.py now logs info.json parse failures to stderr instead of swallowing them.

Security

• Hardened subprocess argv against option injection (#2): inserted -- before the URL in the yt-dlp argv, and tightened is_url to reject --prefixed sources and require a non-empty netloc. Resolved video/audio paths to absolute via Path.resolve() before passing to ffmpeg/ffprobe, so a relative path starting with - can't be misinterpreted as a flag.

[0.1.2] — 2026-04-24

Fixed

• Windows console crash: removed the emoji from the long-video warning in watch.py; cp1252 consoles couldn't encode it.
• setup.py now prints winget / pip install commands on Windows instead of "unsupported platform" — matches what the README already promised.

Changed

• SKILL.md notes that on Windows the scripts must be invoked with python, not python3 (the latter is the Microsoft Store stub on Windows).

[0.1.1] — 2026-04-24

Fixed

• Added commands/watch.md shim so /watch is callable when installed as a Claude Code plugin. Without it, the plugin loaded but the skill wasn't exposed as a slash command.
• scripts/build-skill.sh now strips commands/ from the claude.ai .skill bundle alongside hooks/ and .claude-plugin/.

[0.1.0] — 2026-04-24

Initial marketplace release.

Added

• /watch <url-or-path> [question] slash command.
• yt-dlp download with native caption extraction (manual + auto-subs).
• ffmpeg frame extraction with auto-scaled fps (≤2 fps, ≤100 frames, duration-aware budget).
• --start / --end focused mode with denser frame budget and transcript range filtering.
• Whisper fallback (Groq preferred, OpenAI secondary) for videos without captions.
• setup.py preflight: silent --check, structured --json, and installer that auto-runs brew install on macOS.
• Session-start hook that prints a one-line status on first run / partial config.
• .skill bundle packaging for claude.ai upload via scripts/build-skill.sh.
