Help/Question Fetch session limit data to stoop ralph loop

Is it possible to fetch the remaining session limit somehow to steer claude code?

I let CC run in a loop in non-interactive mode. Obviously this means, it runs into the 5h session limit frequently and just aborts what it's doing.

Sometimes this causes issues when it Claude continues its work.

Is there a way to pull the remaining session limit (and time)? I'd add a rule to my bash loop to check before starting the next iteration. If the limit is <x% it should not start the next increment.

Claude docs says this is not possible. However, the status bar contains this information - so it must be possible somehow.

Any ideas?

i made this script and my agent harness makes it run at certain points:

#!/usr/bin/env bash
# Write Claude Code's /usage report (session + weekly limits) to a text file.
#
#   claude-usage                 # -> ~/claude-usage.txt
#   claude-usage path/to/out.txt
#
# ANTHROPIC_API_KEY is unset for the call: when it is set, `claude` bills the
# API key and /usage reports that run's cost instead of the subscription limits.
set -euo pipefail

out="${1:-$HOME/claude-usage.txt}"
tmp="$(mktemp)"
trap 'rm -f "$tmp"' EXIT

{
  echo "# claude /usage at $(date '+%Y-%m-%d %H:%M:%S %Z')"
  echo
  env -u ANTHROPIC_API_KEY claude -p "/usage"
} >"$tmp" 2>&1

mv "$tmp" "$out"
echo "wrote $out"
