Session Diff

Compare two sessions to see what changed.

Step 1: Resolve session paths

If the user provides two session IDs, resolve them:

bun run ${CLAUDE_PLUGIN_ROOT}/lib/session-store.ts list --project "$(basename $(pwd))" --limit 2

Use the

path

fields from the results.

Step 2: Run the diff

bun run ${CLAUDE_PLUGIN_ROOT}/lib/session-parser.ts diff <session-a.jsonl> <session-b.jsonl>

Step 3: Interpret and present

The script outputs raw structural data. Your job is to synthesize the narrative:

What was the focus of each session? (use
```
first_user_messages
```
)
Files added/dropped/common between sessions
Branch changes (did they switch branches?)
Tool usage shifts (more editing? more reading? more testing?)
Continuity — does session B pick up where A left off?

Present as a side-by-side comparison with your interpretation.
