rate_limits field never populated in statusLine/hook input JSON (v2.1.278)

Description

The rate_limits field is consistently null / absent in the JSON payload sent to both statusLine commands and hook scripts. The comment in the generated statusline.sh template says this works in v2.1.251+, but it does not appear in v2.1.278.

Steps to reproduce

1. Configure a statusLine command in settings.json that logs its input JSON to a file, e.g.:

``sh
#!/bin/bash
INPUT=$(cat)
echo "$INPUT" >> /tmp/sl_input.json
``

1. Run any Claude Code session.

1. Inspect /tmp/sl_input.json:

{
  "session_id": "...",
  "version": "2.1.278",
  "cost": { ... },
  "context_window": { ... },
  ...
}

rate_limits is not present in the payload at all (not null — simply absent).

Expected behavior

The generated statusline.sh template references the following fields and the inline comment promises they are populated server-side:

FIVE_H_USED=$(echo "$input" | jq -r '.rate_limits.five_hour.used_percentage // empty')
WEEK_USED=$(echo "$input" | jq -r '.rate_limits.seven_day.used_percentage // empty')
SPEND_USED=$(echo "$input" | jq -r '.rate_limits.spend_limit.used_percentage // empty')

Comment in the template:

The $500/month allowance is a Claude apps gateway spend limit, reported server-side via rate_limits.spend_limit (Claude Code v2.1.251+)

All three fields should be included in the statusline/hook input payload.

Actual behavior

rate_limits is never present. The monthly spend progress bar (mo ██████░░ 77%) coded in statusline.sh never renders because SPEND_USED is always empty.

The usage is visible at https://claude.ai/code#settings/usage (showing $386 / $500, 77%), so the data exists server-side.

Environment

• Claude Code version: 2.1.278
• OS: macOS 25.6.0 (Darwin)
• Shell: zsh
• statusLine.refreshInterval: 1 (so the command fires every second)
• Hooks also call the same statusline script — rate_limits absent in both hook and statusLine contexts
