Implement or rework Seaborg Backlog.md tasks in a dedicated task branch and worktree, commit task-scoped code and lifecycle metadata, and prepare an immutable target for independent review. Use when Codex is asked to select, claim, implement, continue, or address review findings for a task in To Do or Changes Requested. Do not use for independent review, approval, pushing, merging, or moving a task to Done; use the review skill for review.
Independently review a committed Seaborg Backlog.md task implementation in its existing task branch and worktree, then commit an approval or structured changes-requested verdict on that branch. Use when a task is In Review and Codex must inspect its full diff, verify acceptance criteria, run checks, and update Backlog without fixing implementation code. Do not use to implement findings, create a replacement review branch, push, merge, or move a task to Done; use the implement skill for rework.
Land an approved Seaborg Backlog.md task onto the primary branch through a merge-time integration gate, then record Done. Use when a task is Ready to Merge and a human invokes Codex to integrate it. The skill merges the approved immutable target onto the live primary tip, re-runs required checks and hot-path benchmarks on the integrated result, and fast-forwards primary only if that result is clean and green. Do not use to implement, review, or approve work, and do not rebase or rewrite the approved target; use the implement and review skills for those.
