Explain Utilities

ait explain-runs

Manage aitask-explain run directories. The /aitask-explain skill generates reference data (git history analysis, task/plan mappings) in directories under .aitask-explain/. Over time these accumulate. Use ait explain-runs to list, inspect, and clean up old run data.

Interactive mode (default — requires fzf):

ait explain-runs

Presents a list of all existing runs (both top-level and codebrowser) with file counts and previews. Select a run to delete it, or choose “Delete ALL runs” to remove everything. Confirmation is required before deletion.

Batch mode (CLI flags):

ait explain-runs --list                                              # List all runs with their files
ait explain-runs --delete .aitask-explain/aiscripts__lib__20260226_155403  # Delete a specific run
ait explain-runs --delete-all                                         # Delete all runs
ait explain-runs --cleanup-stale                                      # Remove stale runs (keep newest per source)

Run directory naming:

Run directories use the format <dir_key>__<timestamp>, where dir_key identifies the source directory that was analyzed (e.g., aiscripts__lib for .aitask-scripts/lib/) and timestamp is YYYYMMDD_HHMMSS. This naming allows the cleanup tools to identify which runs correspond to the same source directory and remove older duplicates.

Run directory structure:

Each run is stored as .aitask-explain/<dir_key>__<timestamp>/ and contains:

• files.txt — list of files that were analyzed
• reference.yaml — structured line-to-commit-to-task mapping
• tasks/ and plans/ — extracted task and plan files for context

Codebrowser runs are stored under .aitask-explain/codebrowser/<dir_key>__<timestamp>/ with the same structure. See the Code Browser documentation for details on how annotations are displayed.

Safety:

• The --delete option validates that the target path is under .aitask-explain/ before removing
• The .aitask-explain/ parent directory is automatically removed if empty after deletion
• Interactive mode requires explicit confirmation before any deletion

ait explain-cleanup

Remove stale aitask-explain run directories, keeping only the newest run per source directory key. This prevents disk usage from growing unboundedly as new analysis runs are generated.

Stale cleanup also happens automatically when the /aitask-explain skill generates new data and at codebrowser TUI startup — this command is for manual cleanup or automation.

ait explain-cleanup --all                                   # Clean both top-level and codebrowser runs
ait explain-cleanup --target .aitask-explain/codebrowser          # Clean only codebrowser runs
ait explain-cleanup --dry-run --all                          # Preview what would be removed
ait explain-cleanup --all --quiet                            # Silent mode for automation

How it works:

The script groups run directories by their dir_key (the part before __<timestamp>). For each group, it keeps the newest run (highest timestamp) and removes all older ones. Directories without the expected naming pattern or without files.txt/raw_data.txt are skipped.
