Conciseness

The body is dense, directive, and assumes competence — it never explains git worktrees, CI, or PR mechanics — but the review/CI-proof requirement is stated three times (Role contract, §4 completion, §6 merge) and the max-parallel rule twice, which is deliberate emphasis yet trimmable. That matches anchor 4 ("minor instances that could be trimmed") better than the every-token-earns-its-place anchor 5.

Actionability

Concrete, executable material is abundant: a complete 12-line bash PRP-store resolver, `timeout 1800 gh pr checks <n> --required --watch --fail-fast`, `gh pr diff <n> --name-only`, exact paths like `$PRP_DIR/orchestration/<run-id>.md` with a `YYYY-MM-DD-<slug>` run-ID format, and an engine-selection mapping. Minor gaps remain — no literal merge command or method, and digest/handoff formats are deferred to a template — matching anchor 4 over the fully copy-paste-ready anchor 5.

Workflow Clarity

A clearly sequenced 7-phase lifecycle (Intake/gate → Initialize → Launch → Monitor/steer → Hold gates → Integrate → Close out) with explicit validation at every phase: review and CI proof re-verified "before acceptance and again before merge", merge-commit reachability from `origin/<base>`, resume verification against live state, and destructive-action gates ("Never delete a branch or worktree with unmerged commits"). Feedback loops (watcher timeout re-arm, two-restart escalation, rebase/conflict handling) and a 7-question design checklist satisfy the anchor-5 pattern; the batch/destructive validation cap does not apply.

Progressive Disclosure

The Resources section clearly signals `references/launching.md` with its contents and read timing ("Read it before the first launch"), and the file exists, is one level deep, and delivers what is promised. However, the body also references `templates/orchestration-run.md` ("the required durable run format") twice, and that file is absent from the bundle — a minor navigation gap matching anchor 4 rather than the fully clean anchor 5.

Specificity

Lists several specific actions — "owns the combined outcome, steers autonomous deliveries, holds human and merge gates, verifies proof, and sequences merges" — covering the orchestration lifecycle. They are responsibility-level rather than artifact-level operations and omit intake, queueing, and run-record maintenance, so coverage has minor gaps (anchor 4) rather than the fully comprehensive coverage of anchor 5.

Completeness

Explicitly answers both: what — "Turns the current session into the operator's SDLC proxy for parallel PRP workstreams in isolated worktrees… verifies proof, and sequences merges" — and when — "Use when the user wants to… or invokes /prp-orchestrate" with concrete trigger phrases. This matches the anchor-5 example structure exactly.

Trigger Term Quality

Six natural quoted trigger phrases plus the slash invocation — "spawn N agents in separate worktrees", "run prp-issue on these issues in parallel", "orchestrate these features", "act as my orchestrator", "coordinate agents through the PRP pipeline", "ship these issues in parallel" — comprehensively cover the synonyms a user would naturally say for multi-agent orchestration.

Distinctiveness Conflict Risk

It carves a clear niche — coordinating parallel PRP workstreams across isolated worktrees — and every trigger phrase expresses multi-workstream coordination, keeping conflict risk with single-workstream PRP skills (prp-issue, prp-plan, prp-implement) minimal.
