Cleanup Review

python scripts/_cache_clear.py is an optional cleanup helper for the Quark Subtitle Rescue skill. It may recursively remove /tmp/skill_build/*, /tmp/skill_build/.cache. Show the exact paths first, explain whether they are skill-private temporary paths or user state, and run the cleanup only after the user confirms.

Quark Subtitle Rescue

High-success, low-risk workflow for Quark 网盘字幕批处理。

What this skill solves

• One-click style recovery for: “给电影文件夹所有子目录补字幕”
• Resume from partial progress after interruptions/429/timeout
• Reduce bad matches via strict retries and staged fallback
• Keep an auditable trail: progress, failures, and final completion report

Use this skill when

• User asks for batch subtitles across many Quark subfolders
• Previous run is partially done and needs rescue/retry
• Need to switch subtitle providers for better hit rate
• Need safe rollback/checks after suspected wrong matches

Don’t use this skill when

• User only needs subtitle for a single local file
• There is no valid Quark login/cookie context

Quick Start

1. Confirm tool root exists: quark_subtitle_tool/.
2. Ensure config exists: ~/.config/quark_subtitle.json with valid cookie.
3. Activate venv: source quark_subtitle_tool/venv/bin/activate.
4. Run staged workflow (below), do not jump directly to aggressive retries.

Minimal inputs expected

• Quark target path (example: 全部文件/来自：分享/电影)
• Subtitle preference (default: bilingual zh+en)
• Whether to allow Chinese-only fallback when bilingual is unavailable

Staged Workflow

Stage 1 — Baseline batch run

Run:

python quark_subtitle_tool/batch_subtitle_runner.py

Check output:

• quark_subtitle_tool/quark_work/batch_progress.json
• quark_subtitle_tool/quark_work/batch_failures.jsonl

Stage 2 — Strict retry on failures

Run strict retry (avoid broad fuzzy terms like director names):

python quark_subtitle_tool/strict_top10_retry.py
python quark_subtitle_tool/strict_remaining_retry.py

Rule: prioritize title + year; avoid generic query terms.

Stage 3 — Folder-specific rescue

If one folder remains stubborn, run dedicated script for that folder with filename-derived queries (example scripts in quark_subtitle_tool/*_retry.py).

Stage 4 — Final two/small-tail manual precision

For 1–5 leftovers, use explicit aliases (English original title + year), then run a targeted retry script.

Provider Order and Matching Policy

Default order:

1. OpenSubtitles
2. SubHD (射手系)
3. YIFY
4. Legacy providers (podnapisi/subtis/tvsubtitles)

Policy:

• If provider N hits, stop and do not query lower-priority providers.
• Default success target: bilingual (zh+en). If bilingual is unavailable, fall back to Chinese-only only when user allows it.
• Treat “search page hit” and “download hit” separately; only download hit counts as success.

Safety Guardrails (Mandatory)

1. Never use broad person-name queries (e.g., director name) for batch upload.
2. If many files suddenly “succeed” with same query, run hash-based spot check before declaring success.
3. If wrong-match batch is found, rollback before continuing.
4. Produce a clear report: total / success / failed / pending folders.

• OpenSubtitlesCom Bad Request
• dogpile RegionNotConfigured
• 429 rate limits
• folder enter failures due to special chars
• delete/rollback auth failures
