One transcript record can exceed a megabyte or embed a whole history. Printing one whole record can overflow the context of the session doing the diagnosis. Every reader of a session file, controller or subagent, follows these rules for every file, every time.
Measure before reading.
wc -lc "$F"
awk '{ if (length($0) > 100000) print NR, length($0) }' "$F" # long linesNever cat or grep for content. Get line numbers and counts
first (grep -n … | cut -d: -f1, jq -r '.type' | sort | uniq -c),
then small fields from specific lines (sed -n Np | jq -c '{…}' or
| cut -c1-500). Use the field-extraction commands established during
discovery for the source in front of you.
Narrow anything over 500 characters. If a command returns more than 500 characters for one record, tighten the field or the slice.
Read-only. Never modify, move, or delete a session file.
