# Error Handling Reference
- `#N` not found: report and list open issues with `gh issue list -R Jamie-BitFlight/claude_skills --state open`
- `#N` already closed: warn and stop; offer `close` or `resolve` if needed
- `close #N` / `resolve #N` — issue not found: report and stop
- Item not found: list available items from `.claude/backlog/` per-item files with their priority sections
- Multiple matches: present numbered list, ask user to choose
- Grooming fails: proceed without grooming context, note the gap in the feature request
- RT-ICA returns BLOCKED: present missing inputs, wait for user, do not invoke `add-new-feature`, do not set `status:in-progress`
- `add-new-feature` fails: report the failure, do not update per-item file
- Plan file not found after planning: search `plan/` directory broadly, ask user to confirm the path
- Grooming reports directory does not exist: treat all items as ungroomed
- `close` with no `**Plan**:` field: report and offer `resolve` as alternative
- `close` with incomplete checklist: list remaining tasks, do not close
- `close` with verification FAIL: report per-criterion gaps, do not close
- `close` on already-completed item: report closed date, do not re-close
- `resolve` with no reason provided: block until user provides reason (reason is required evidence)
- GitHub issue creation fails: report error, continue with per-item-file-only workflow; do not block SAM planning
- `gh` not installed: run `uv run .claude/skills/gh/scripts/setup_gh.py` first
- Label not found during issue create: `github_project_setup.py` creates it automatically
- Milestone not found: skip milestone assignment; do not fail
- `resume` with no `**Plan**:` field: offer to create a plan with `/work-backlog-item {title}`
- `progress` with no active milestone: show backlog counts only; note no milestone found
- `--quick` plan write fails: report and stop; do not update per-item file
