Conciseness

The body is command-first and lean — full bash invocations with no explanation of concepts Claude already knows — but contains minor trimmable redundancy: "You don't write code directly" in Role Definition is restated as "Don't write code directly" in Core Rules, and the [AI]/[USER] marker table plus user-facing tables add overhead. This matches the 4-anchor ("efficient; minor instances that could be trimmed") rather than 5, since not every section earns its place.

Actionability

Mostly executable, copy-paste-ready commands (task.py create/init-context/set-branch/set-scope/add-context/validate, multi_agent/plan.py and start.py with concrete flags), with one notable gap: Option A instructs `start.py "$TASK_DIR"` but never shows how TASK_DIR is assigned after plan.py runs. This fits the 4-anchor ("concrete code or commands with minor gaps"), not 5 ("fully executable… specific examples cover the common cases").

Workflow Clarity

The sequence is clear: a 4-step startup flow, explicit decision criteria for Option A vs B, and Option B includes a validation checkpoint ("python3 ./.trellis/scripts/task.py validate \"$TASK_DIR\"") before starting. However, there is no error-recovery feedback loop (what to do when validate fails) and no guidance for when plan.py "may reject if unclear/too large", so it matches the 4-anchor rather than 5 ("explicit validation steps; feedback loops for error recovery").

Progressive Disclosure

There are no bundle files (references/, scripts/, assets/ are absent) and the skill is a single well-organized file with clear section headers (Startup Flow, Planning, Monitoring, Core Rules), so navigation is easy. It sits at the 4-anchor ("good structure; most content appropriately placed; minor organization gaps") rather than 5 because user-facing content (the User Available Skills table and Monitoring Commands) is inlined in an AI-facing skill and the file is ~190 lines rather than a compact overview pointing elsewhere.

Specificity

The description lists multiple concrete actions covering the full orchestration cycle — "plans and dispatches parallel development tasks to worktree agents", "Reads project context", "configures task directories with PRDs and jsonl context files", and "launches isolated coding agents" — including concrete artifacts like PRDs and jsonl context files. This matches the 5-anchor ("multiple specific concrete actions; comprehensive coverage") rather than 4, since no meaningful AI-executed action in the workflow is omitted.

Completeness

It clearly answers both questions: the "what" (orchestrate, read context, configure task directories, launch agents) and an explicit "when" ("Use when multiple independent features need parallel development, orchestrating worktree agents, or managing multi-agent coding pipelines"). This matches the 5-anchor pattern of both what and when with concrete trigger phrases, not the 4-anchor where the when is only adequate.

Trigger Term Quality

The "Use when" clause includes good natural keywords — "multiple independent features need parallel development", "orchestrating worktree agents", "managing multi-agent coding pipelines" — that users would plausibly say. It falls short of the 5-anchor because common variations and synonyms like "parallelize", "run tasks concurrently", or "multiple features at once" are missing.

Distinctiveness Conflict Risk

Phrases like "Multi-agent pipeline orchestrator", "worktree agents", and "multi-agent coding pipelines" establish a clear niche with distinct triggers that few other skills would share. It fits the 5-anchor ("clear niche with distinct triggers; minimal conflict risk") rather than 4, since overlap risk with closely related skills is minimal.
