Conciseness

The body is dense procedural instruction with zero concept explanations — git, worktrees, buses and compaction are all assumed ("Watch for signs that a Worker is losing context: it says its context was compacted, repeats finished work, ignores the Rules"). Every line directs behavior; no padded sections exist, matching the lean anchor-5 profile.

Actionability

For an instruction-only skill the guidance is fully concrete: exact paths (".apm/bus/manager/handoff.md", "AGENTS.md"), exact skill names to invoke ("apm-5-check-reports", "apm-8-summarize-session"), precise section pointers ("{GUIDE_PATH:task-assignment} §1"), and explicit decision branches ("If it has content, continue with §1.2; otherwise this is the first Manager, so continue with §1.1"). Per the rubric's instruction-skill note, the absence of code is not penalized.

Workflow Clarity

Sequences are numbered with explicit validation checkpoints and feedback loops: "Wait for approval, apply corrections and ask again", "Check what they say about branches, merges, Worker buses and pending reviews against the Tracker, the bus files and, with version control, git. Where they differ, trust the current files and git", and "Wait for confirmation that every active Worker has stopped writing" before recording state — the anchor-5 pattern including error-recovery guidance.

Progressive Disclosure

The body stays a role overview and delegates the mechanics one level deep through clearly signaled references ("{GUIDE_PATH:task-review}", "{SKILL_PATH:apm-communication}", "apm-6-handoff-manager"), with clean section structure (Initiation, Coordination Cycle, Session Completion, Subagents). No bundle files exist to inline instead, and no content that belongs elsewhere is embedded — matching the anchor-5 structure.

Specificity

"Initiate an APM Manager" names the domain but relies on a single generic action — structurally the same as the anchor-2 example "Processes PDF files". It does not reach anchor 3 because no concrete actions of the Manager (dispatching Tasks, reviewing reports, maintaining the Tracker) are stated.

Completeness

It has both parts: "Initiate an APM Manager" (what) and "Use only when the User manually invokes this skill" (an explicit when, so not capped at 3). It falls short of anchor 5 because the 'what' is a single thin action and the 'when' offers no concrete trigger phrases beyond the manual-invocation restriction.

Trigger Term Quality

"APM Manager" and "manually invokes" are relevant, non-generic keywords a user of this system would naturally say, but no variations or synonyms (e.g., "start", "coordinator", skill-name mention) appear. This matches anchor 3 — some relevant keywords, missing common variations — rather than anchor 4's good coverage.

Distinctiveness Conflict Risk

"APM Manager" carves a clear niche and the "Use only when the User manually invokes this skill" gating limits misfires, but the APM family contains closely related Manager skills (e.g., apm-6-handoff-manager), leaving minor overlap risk — anchor 4 rather than 5's minimal-conflict profile.
