Returns the next available sequence number for files in a directory. Run the script and use its stdout directly. The script is the single source of truth for the numbering logic.
~/.claude/skills/auto-number/auto-number.sh <directory> [--mode prefix|suffix] [--glob PATTERN] [--width N]
Arguments:
directory (required, positional) -- path to scan for existing numbered files--mode (optional) -- prefix for NNNN-name.ext or suffix for name-NNNN.ext. Default: prefix. Omit --mode entirely when you want prefix mode: it is the default.--glob (optional) -- file filter pattern (e.g., *.txt). Default: all files--width (optional) -- output width, 1-10. Default: 4. Safety: never truncates if next value needs more digitsOutput: A single line with the next number, zero-padded to width (e.g., 0001 at default width, or 000042 with --width 6).
# Next prefix number in .claude-work/issues/5/commit-msgs/ (default mode, default width)
# NOTE: do NOT pass "prefix" as a positional argument. Just omit --mode
~/.claude/skills/auto-number/auto-number.sh .claude-work/issues/5/commit-msgs
# Next suffix number, only counting .json files
~/.claude/skills/auto-number/auto-number.sh some/dir --mode suffix --glob "*.json"
# Next number with 6-digit padding
~/.claude/skills/auto-number/auto-number.sh some/dir --width 6
WRONG: prefix is not a positional argument:
# This will fail with: E002 error: unexpected argument 'prefix'
~/.claude/skills/auto-number/auto-number.sh .claude-work/issues/5/scratchpads prefix
RIGHT: omit --mode entirely for prefix (it is the default):
~/.claude/skills/auto-number/auto-number.sh .claude-work/issues/5/scratchpads
RIGHT: use --mode flag when explicitly specifying a mode:
~/.claude/skills/auto-number/auto-number.sh .claude-work/issues/5/scratchpads --mode suffix
0001 (at default width) if the directory is empty or has no matching filesreport-0042.tar.gz becomes report-0042.tar), so files with compound extensions are silently skipped--width 3 with max 999 outputs 1000)All errors exit 1 with a message on stderr in the format auto-number EXXX error: <details>. Codes use two ranges: E0xx for generic errors (missing required arguments, unknown flags) and E1xx for parameter validation (invalid values, directory problems).
