description

Select the most appropriate pipeline for a user goal, lock it in `PIPELINE.lock.md`, and route checkpoint questions into `DECISIONS.md`. **Trigger**: pipeline router, choose pipeline, workflow selection, PIPELINE.lock.md, 选择流程. **Use when**: 用户目标/交付物不清晰，需要在 snapshot/survey/tutorial/systematic-review/peer-review/idea-finder 中选一个并设置最小 HITL 问题集。 **Skip if**: pipeline 已锁定（`PIPELINE.lock.md` 存在）且所需问题已回答/签字完成。 **Network**: none. **Guardrail**: 尽量一次性提问；信息不足就写 `DECISIONS.md` 并停下等待。

Pipeline Router

“Routing” usually means two different things:

• Pipeline selection + lock: choose a single pipeline and write PIPELINE.lock.md.
• Checkpoint routing: keep the run auditable by drafting/updating checkpoint blocks in DECISIONS.md (and, for C0, seeding queries.md from GOAL.md).

This skill supports both, but keeps the semantic choice LLM-first and the repetitive checkpoint scaffolding scriptable.

Inputs

Workspace context (when available):

• GOAL.md
• STATUS.md
• DECISIONS.md
• PIPELINE.lock.md

Optional template:

• assets/pipeline-selection-form.md

Outputs

• PIPELINE.lock.md (Mode A; selection + lock)
• Updates to DECISIONS.md (all modes; checkpoint blocks + approvals checklist)
• queries.md (best-effort for C0; seeded from GOAL.md)
• Optional: updates to STATUS.md

Decision tree (selection)

User goal → choose:

• “survey / 综述 / 调研” → pipelines/arxiv-survey.pipeline.md
• “survey + PDF / LaTeX / 可编译” → pipelines/arxiv-survey-latex.pipeline.md
• “tutorial / 教程” → pipelines/tutorial.pipeline.md
• “systematic review / PRISMA / 系统综述” → pipelines/systematic-review.pipeline.md
• “peer review / 审稿” → pipelines/peer-review.pipeline.md
• “idea / ideation / brainstorm / 找 idea / 选题 / 点子” → pipelines/idea-finder.pipeline.md
• “snapshot / 速览” → pipelines/lit-snapshot.pipeline.md

Workflow

Mode A — selection + lock (LLM-first)

1. Read the goal from GOAL.md (or the user message).
2. If key details are missing, use assets/pipeline-selection-form.md to draft a concise question list into DECISIONS.md and stop.
3. Select exactly one pipeline under pipelines/*.pipeline.md.
4. Write PIPELINE.lock.md with:
   • pipeline: <path>
   • units_template: <path from pipeline front matter>
   • locked_at: <YYYY-MM-DD>
5. Update STATUS.md (“Current pipeline” + checkpoint).

Mode B — checkpoint blocks (script helper)

Use the helper to keep DECISIONS.md in sync with checkpoints:

• Kickoff questions + seed queries (C0):
  • python .codex/skills/pipeline-router/scripts/run.py --workspace <ws> --checkpoint C0
• Scope/outline approval summary (C2):
  • python .codex/skills/pipeline-router/scripts/run.py --workspace <ws> --checkpoint C2
• Other checkpoints:
  • python .codex/skills/pipeline-router/scripts/run.py --workspace <ws> --checkpoint C1

Quality checklist

• DECISIONS.md has a checkpoint block for the active C*.
• Approvals checklist exists and includes Approve C* checkboxes.
• If selection was needed, PIPELINE.lock.md points to exactly one pipeline file.
• If the run is retrieval-based, queries.md is non-empty after C0 seeding.

Side effects

• Allowed: create/update PIPELINE.lock.md; edit STATUS.md; append/update DECISIONS.md; seed queries.md.
• Not allowed: modify files under .codex/skills/ assets/templates.

Script

Quick Start

• python .codex/skills/pipeline-router/scripts/run.py --help
• python .codex/skills/pipeline-router/scripts/run.py --workspace <workspace_dir> --checkpoint C0

All Options

• --checkpoint <C0|C1|C2|...>: which checkpoint block to draft/update (unknown checkpoints get a generic template)

Examples

• Kickoff questions + seed queries:
  • python .codex/skills/pipeline-router/scripts/run.py --workspace <ws> --checkpoint C0
• Generic protocol approval block (systematic review C1):
  • python .codex/skills/pipeline-router/scripts/run.py --workspace <ws> --checkpoint C1
• Scope/outline approval summary:
  • python .codex/skills/pipeline-router/scripts/run.py --workspace <ws> --checkpoint C2

Notes

• python scripts/pipeline.py kickoff|init writes PIPELINE.lock.md and then (best-effort) runs this script for C0.
• The script reads PIPELINE.lock.md (if present) to display the pipeline in the kickoff block; it does not choose the pipeline.

Troubleshooting

Issue: PIPELINE.lock.md points to one pipeline but UNITS.csv looks like another

Cause:

• Workspace was initialized from one pipeline and later re-pointed without updating UNITS.csv.

Fix:

• Re-run python scripts/pipeline.py init --workspace <ws> --pipeline <name> --overwrite-units, or copy the correct templates/UNITS.*.csv into UNITS.csv.
