Add pr-to-green skill and CI/conflict subagents#737
Merged
Conversation
Introduce three new docs: a CI failure investigator agent (.cursor/agents/ci-failure-investigator.md), a merge conflict analyst agent (.cursor/agents/merge-conflict-analyst.md), and a PR-to-green workflow skill (.github/skills/pr-to-green/SKILL.md). These add repository-specific triage and conflict-resolution guidance (failure-family grouping, root-cause ranking, minimal patch plans, verification commands), strict output formats, escalation rules for high-risk conflicts (notebooks, core contract changes), and CausalPy guardrails (conda command conventions, test placement, non-destructive git practices). Designed to standardize automated/manual maintainer workflows for syncing PRs and restoring CI green.

Summary
Adds a
pr-to-greenskill and two supporting Cursor subagents to streamline the maintainer workflow for getting PRs to a mergeable state.pr-to-greenskill (.github/skills/pr-to-green/SKILL.md): deterministic workflow for syncing a PR branch with base, resolving conflicts, fixing failing checks, pushing, and verifying remote CI. Includes early exit when PR is already green, an iteration loop for cascading failures, and explicit maintainer escalation for complex conflicts (especially.ipynb).ci-failure-investigatorsubagent (.cursor/agents/ci-failure-investigator.md): triages noisy/multi-job CI failures into root-cause rankings and minimal fix plans. Runs onfastmodel to keep cost low.merge-conflict-analystsubagent (.cursor/agents/merge-conflict-analyst.md): classifies conflicts by risk, auto-resolves mechanical ones, and escalates semantic/high-risk conflicts (especially notebooks and core contracts) to the maintainer with options and trade-offs.Usage
Invoke in Cursor chat with a PR number:
The skill fetches PR metadata from GitHub, checks out the branch, and walks through sync/fix/push/verify. If the PR is already green it exits early. Subagents are delegated automatically when CI logs are noisy (
ci-failure-investigator) or merge conflicts are non-trivial (merge-conflict-analyst).
