cursor-rescue
GitHub诊断并修复 Harness 工作流中 Cursor 后端故障。用于处理 cursor:rescue 调用、Cursor 委派失败、cursor-agent 缺失、setup-cursor 错误或后端意外回退至 claude 的场景，提供根因分析与最小化修复方案。
Trigger Scenarios
用户调用 cursor:rescue
Cursor 委派失败
cursor-agent 缺失
setup-cursor 失败
后端解析意外回退到 claude

cursor:rescue - Cursor Backend Recovery
Cursor backend の failure path を短く切り分ける skill。変更は最小限にし、破壊的操作はしない。
Quick Reference
cursor:rescue "breezing fell back to claude"
cursor:rescue "cursor-agent not found"
Diagnosis Order
Run one compact diagnostic block:
set +e
HARNESS_PLUGIN_ROOT="${HARNESS_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT:-}}"
if [ -z "$HARNESS_PLUGIN_ROOT" ] && [ -n "${CLAUDE_SKILL_DIR:-}" ]; then
probe="$(cd "${CLAUDE_SKILL_DIR}" && pwd)"
while [ "$probe" != "/" ] && [ ! -d "$probe/scripts" ]; do
probe="$(cd "$probe/.." && pwd)"
done
[ -d "$probe/scripts" ] && HARNESS_PLUGIN_ROOT="$probe"
fi
if [ -z "$HARNESS_PLUGIN_ROOT" ]; then
echo "ERROR: HARNESS_PLUGIN_ROOT is not set and could not be derived from CLAUDE_PLUGIN_ROOT or CLAUDE_SKILL_DIR" >&2
exit 2
fi
echo "==RESOLVED_BACKEND=="
bash "${HARNESS_PLUGIN_ROOT}/scripts/resolve-impl-backend.sh" --role worker
echo "==USER_OR_PROJECT_DEFAULT=="
bash "${HARNESS_PLUGIN_ROOT}/scripts/set-impl-backend.sh" --show
echo "==CURSOR_MODEL=="
bash "${HARNESS_PLUGIN_ROOT}/scripts/model-routing.sh" --host cursor --role worker --field model
echo "==CURSOR_AGENT=="
CURSOR_AGENT_BIN="${CURSOR_AGENT_BIN:-}"
if [ -z "$CURSOR_AGENT_BIN" ]; then
if command -v cursor-agent >/dev/null 2>&1; then
CURSOR_AGENT_BIN="$(command -v cursor-agent)"
elif [ -x "$HOME/.local/bin/cursor-agent" ]; then
CURSOR_AGENT_BIN="$HOME/.local/bin/cursor-agent"
fi
fi
if [ -z "$CURSOR_AGENT_BIN" ]; then
echo "NOT_INSTALLED: cursor-agent not found in PATH or $HOME/.local/bin"
else
"$CURSOR_AGENT_BIN" --version
fi
echo "==CURSOR_PACKAGE_CHECK=="
bash "${HARNESS_PLUGIN_ROOT}/scripts/setup-cursor.sh" --check
Common Fixes
| Symptom | Fix |
|---|---|
cursor-agent missing |
Install / sign in to Cursor CLI, then rerun cursor:setup --check. |
backend resolves to claude unexpectedly |
Run bash scripts/set-impl-backend.sh --show; set user default with cursor:setup --user-default or project default with cursor:setup --project-default. |
setup-cursor.sh --check fails |
Report the first failing [ERR] line and the missing file path. |
| companion exits 2 | Workspace guard or forbidden path. Recreate an isolated worktree and retry. |
| companion exits 3 | cursor-agent not found in PATH or $HOME/.local/bin. |
Output
Return:
- root cause candidate
- exact failing command
- minimal fix command
- whether retrying the original workflow is safe
