Conciseness

The body is lean and instruction-dense: every paragraph carries directives ("Read these files in full", "Create `.apm/bus/<agent-slug>/`", "Keep each approval gate"), and the APM methodology background ("Workers do not read the Spec or Plan") is novel context Claude cannot know, not padding. This matches anchor 5 (lean, assumes competence, every token earns its place) rather than 4 because there is no over-explanation to trim.

Actionability

Guidance is mostly executable: exact bus file structure ("empty `task.md`, `report.md` and `handoff.md`, and `.apm/bus/manager/` with only an empty `handoff.md`"), a named next skill ("invoking `apm-2-initiate-manager`"), and a concrete survey checklist (Git status, branches, `.apm/archives/`, `AGENTS.md`). It is anchor 4 rather than 5 because the planning substance itself is deferred to the external guides, so common-case coverage is not fully contained in this file.

Workflow Clarity

The five numbered sections sequence Initiation → Workspace Survey → Planning → Completion → Subagents, with explicit stop-and-wait checkpoints at every phase transition ("end your message and wait for the reply", "wait for the User to approve each one before you start the next", "Keep each approval gate unless the User explicitly asks to skip it"). These approval gates are the explicit validation steps of anchor 5; no destructive or batch operation applies a cap.

Progressive Disclosure

The file is a well-organized overview with purpose-annotated, one-level-deep references ("`{GUIDE_PATH:context-gathering}`: how to explore the workspace and question the User") and scoped reading guidance ("Read other APM files only when these files point you to them"). It is anchor 4 rather than 5 because the reference targets are unresolved template placeholders rather than verifiable paths, and reading chains through the guides; no bundle files are present to verify the structure against.

Specificity

"Initiate an APM Planner" names the domain and one concrete action, but never states the skill's actual capabilities (exploring the workspace, questioning the User, writing the Spec, Plan and Rules). It matches anchor 3 (domain plus 1-2 concrete actions, not comprehensive) rather than 2 because a real action is named, and not 4 because only one action is listed with no coverage of the rest.

Completeness

Both parts are present: "Initiate an APM Planner" answers what, and "Use only when the User manually invokes this skill" is an explicit when-clause, so the missing-trigger cap does not apply. It sits at anchor 4 (both present, each could be more specific) rather than 5 because the what omits the deliverables and the trigger is not a natural user phrase, and rather than 3 because the when is explicit, not weakly implied.

Trigger Term Quality

Terms like "APM Planner", "initiate" and "manually invokes this skill" are relevant and domain-specific, but natural user variations ("start the planner", "plan this project", "kick off APM") are missing. This is anchor 3 (some relevant keywords, missing common variations or synonyms), not 2 because the keywords are specific rather than generic, and not 4 because coverage is thin.

Distinctiveness Conflict Risk

"APM Planner" is a clear niche role, and "Use only when the User manually invokes this skill" removes any auto-trigger conflict risk with other skills. This clearly matches anchor 5 (clear niche with distinct triggers, minimal conflict risk).
