AI Analysis
●●SolidSolve My ProblemCozy
Second-pass verification before download is a clever constraint for EPUB repairs.
Strengths
- •Names exact failing paths in OPF, manifest, and anchor structures
- •Stops at manual review instead of guessing on content decisions
- •Free, no signup, browser-based for a niche publishing workflow
Weaknesses
- •Very narrow scope limits broader appeal beyond KDP authors
- •EPUB validation tools already exist, though less KDP-specific

Recover bricked Claude Code sessions with "thinking blocks" error
The repo does one painful thing well: it inspects SESSION_ID.jsonl, pinpoints where streaming/interleaving corrupted 'thinking' blocks, and offers diagnose, fix (with auto-backup), and nuke fallbacks. It's pragmatic and ruthless — small CLI commands, clear recovery workflow, and rescue-first guidance — but it's narrowly targeted to Claude Code users and won't matter to most people.
