yeonwoosung/my-claude-code-mods is a collection of custom modes that analyze Claude Code sessions and look at file changes. There is no separate public release information; the features and usage are described in the repository README. According to the repository description, it is a project that gathers the Claude Code modes you need.
The collection focuses on where time and context are spent in a session and where work fails. The agent profiler breaks down the time spent on model waits, tool calls, subagents, and file re-reads, and exports OTLP-format trace data to Jaeger and Tempo. The context inspector finds the items filling the input window and repeated outputs, then examines what remains after compaction. The time travel feature, which leaves a snapshot at every tool call, shows the change history as a branching timeline. The README also describes failure detection, pinning notes and to-dos, showing validation results, allowed-path warnings, checking dependency changes, and file review features.
The README also covers how to install modes individually or all at once, and how to load or manage them in Claude Code sessions. A compatibility table per validation target shows the range confirmed for each engine version, but that table alone cannot tell you about compatibility across real usage environments or how much session time is saved. So this repository can be seen as a tool that gathers features for observing sessions and retracing changes, and its effectiveness and compatibility range need to be checked against your own environment.
