Transcription header shows tools as debug HashMap, not readable list	todo	bug	2026-03-30T04:43:50Z	2026-03-30T04:43:50Z	claudbg-8vpb

Problem

The transcription header line Tools: prints a raw Rust debug-format HashMap, e.g.:

Tools:   {"Bash": 3, "Read": 5, "Write": 2}

Expected behavior

A human-readable comma-separated summary, e.g.:

Tools:   Bash×3, Read×5, Write×2

(or similar format — Name(n), Name: n, etc. — sorted by count descending)

Root cause

src/commands/sessions.rs:427:

println!("Tools:   {:?}", stats.tool_calls);

stats.tool_calls is HashMap<String, u64>. The :? debug format is not user-friendly.

Same issue exists in src/commands/agents.rs transcribe header (prints same stats).

Fix

Format stats.tool_calls by iterating entries, sorting by count descending, and joining as "Name×N". The × (multiplication sign) or (N) notation both work.
