# Backlog triage A backlog only grows while nothing can decline a row. This pass reads every row against the current tree, files one verdict per row for the operator, and later applies what they approved. The record is an ordinary intake folder at `.canon/intake/<nn>-backlog-triage/`. Read `${CLAUDE_SKILL_DIR}/../../standards/intake.md` before writing any file in it, since it holds the item format, the frontmatter, the index shape, and the answer contract this skill is bound by. Read `${CLAUDE_SKILL_DIR}/../../standards/board.md` and `${CLAUDE_SKILL_DIR}/../../standards/tasks.md` before applying, since the first holds the backlog and the ordering file and the second holds the `Declined:` line. ## Guards - Resolve `.canon/tasks/` and `.canon/intake/` at the main worktree root, not `pwd`. Run `git worktree list --porcelain | grep -m 1 '^worktree ' | cut -d' ' -f2-`, falling back to `pwd` outside a git repo. - If `.canon/tasks/backlog.md` does not exist at that root, stop: `❌ No backlog at .canon/tasks/backlog.md. Nothing to triage.` - Never fill a `You:` slot, and never read an empty one as agreement. Answering runs through `plan-intake-answer` or the operator's own edit, which is what keeps silence from deciding a row. - Branch on each `canon` record's `ok` and `reason` rather than on the exit code, which a shell function wrapping `canon` can flatten to zero. ## Step 1: detect the phase Run `canon intake list --json` and take the folders whose slug ends in `-backlog-tria
