Resolve PRBaseBranch for mcp__drm-copilot__collect_pr_context using merge-base ancestry. Use when orchestrators or review workflows need the correct comparison base branch and must select the branch with the most recent common ancestor commit with HEAD.

parallel-add

Admit one new item into a running parallel run — preparation via a preparation-mode child orchestrator run, conflict-edge computation against all items including in-flight ones, and the admission decision that either places the item in the current cohort or defers it and recolors the unstarted subgraph. Appends exactly one mutations[] entry. In-flight items are never moved.

parallel-orchestrate

Execute a prepared parallel run for the parallel-orchestrator agent — cohort scheduling under a max_concurrency cap, per-item fan-out onto isolated worktrees branched from origin/main, per-item merge to main after durably confirming CI green, worktree cleanup, and the generated parallel-status.md projection. There is no integration branch and no final integration pull request.

parallel-plan

Prepare a set of thematically unrelated items for concurrent execution before any execution begins - item intake over issue numbers and potential-entry paths, concurrent preparation-mode child orchestrator delegations, blast-radius computation and V1-V3 validation, cohort seeding with a recomputation-parity check, run-manifest and planner-checkpoint authoring, and the parallel-orchestrator kickoff artifact.

PR Base Branch (Merge-Base)

Deterministic branch-selection rules for PR context collection.

When to Use This Skill

Use this skill when:

running mcp__drm-copilot__collect_pr_context,

delegating post-implementation review that depends on PRBaseBranch,

constructing PR context artifacts where the base must not be hard-coded.

Selection Contract

PRBaseBranch MUST be resolved from git ancestry, not guessed.

Definition of correct base:

choose the candidate branch whose merge-base with HEAD has the most recent commit timestamp,

this implements “find the branch with the most recent commit in common.”

Deterministic Procedure

Enumerate candidate branches from local and remotes, excluding HEAD and detached refs.

For each candidate B, compute merge-base commit M = git merge-base HEAD B.

Compute merge_base_epoch(B) from git show -s --format=%ct M.

Select branch with maximum merge_base_epoch(B).

Tie-breakers (in order):

development
main
master
lexical ascending branch name

Guardrails

Do not default to main unless merge-base resolution fails for all candidates.

If all candidates fail, surface explicit error context and use repository default branch only as last-resort fallback.

Persist chosen PRBaseBranch in orchestration state and reuse it within the same run.

Collector Invocation Rule

When invoking PR context collection, pass the resolved base explicitly:

mcp__drm-copilot__collect_pr_context with base=<resolved-PRBaseBranch>

Evidence Recommendation

For auditability, include in logs/checkpoint:

selected branch name,

selected merge-base SHA,

selected merge-base timestamp,

top competing candidates with timestamps when available.
