[v3.18 ops] sin triage: backlog auto-prioritizer via gh CLI

[Delqhi]

Backlog Triage CLI (sin triage)

A CLI that reads the open issues via gh and produces a prioritized BACKLOG.md based on labels, dependencies, and acceptance criteria.

Why

There are 20+ open issues, ungetriaged. The v0 Agent is working on the Loop-Engineering cluster (#150-155), but the rest (Skill-Fusion, Autopilot, Spec-Layer, CodeGraph) is silent. A triage CLI is the meta-tool that tells the operator "what's next."

SOTA-Agents do this themselves before starting a new task. SIN-Code currently relies on the operator to read the GitHub issue list manually.

What ships

Subcommand: sin triage

sin triage                      # show all open issues, grouped + prioritized
sin triage --label=loop-system  # filter by label
sin triage --format=md > BACKLOG.md  # write to a file
sin triage --format=json        # machine-readable

Prioritization heuristic

For each open issue, compute a score:

Signal	Points
Has epic label	+10
Blocks another issue (via issue reference)	+5 per blocked
Has acceptance text in body	+3
Has no v0 label (= v0 isn't doing it)	+5
Has good first issue label	-3 (deprioritize for the operator, prioritize for new contributors)
Last updated > 30 days	-2
Last updated < 7 days	+1

Then sort by score descending. Output is grouped by label (epic, loop-system, enhancement, etc.).

BACKLOG.md regeneration

A pre-commit hook that runs sin triage --format=md > BACKLOG.md and stages the result. Operator reviews the diff.

Acceptance criteria

• sin triage shows the current backlog, sorted and grouped
• BACKLOG.md is generated correctly, includes the score breakdown per issue
• The CLI is fast (< 2s for 50 issues, uses gh issue list --json once)
• The pre-commit hook is opt-in
• Test coverage ≥ 80%

Mandates

• M1 (n8n CI): the pre-commit hook runs locally, not in CI
• M4 (permission engine): the CLI uses gh (already a dependency), no new perms

Related

• BACKLOG.md (already exists, currently static) — what this CLI regenerates
• cmd/sin-code/internal/ghbridge/ — the gh API wrapper that this could use instead of shelling out
• cmd/sin-code/internal/sin-summary/cmd.go — similar pattern (read state, render)

Estimated scope

~2-3 days, 1 PR, 1 new package cmd/sin-code/internal/triage/ (~400 LOC). Small but high-leverage.

Closed: shipped in PR #203 (feat(triage): sin-code triage CLI with scoring + markdown BACKLOG generator, issue #162). The internal/triage/ package + sin-code triage CLI are live on main with 15 race-clean tests and a deterministic scoring heuristic (epic/blocks/acceptance/loop-system/fusion/etc.).
