Conciseness

The body is two lines — a provenance comment and "Load and follow the shared skill at `~/.agents/skills/handoff/SKILL.md`" — with zero padding and no explanation of concepts Claude already knows. Every token serves the redirect; this matches anchor 5 ("lean and efficient; assumes Claude's competence") and is clearly above anchor 4 since there is nothing to trim.

Actionability

The single instruction is concrete and executable — an exact path to load and follow — but it is a pure pointer with no fallback or verification if the shared skill is absent, and no task guidance (handoff document creation, committing) lives in this bundle. Anchor 4 ("mostly executable guidance; concrete code or commands with minor gaps") fits better than 5, whose "specific examples cover the common cases" cannot be satisfied when all substance is external and unverifiable.

Workflow Clarity

The one step the body defines (load the shared skill at the given path) is unambiguous, which the simple-skill note rewards. It falls short of 5 because the body fronts a multi-step, state-changing task (author a document and git commit it, per the description) whose entire sequence and validation are delegated to an external file, and there is no checkpoint confirming the shared skill actually loaded — a minor validation gap characteristic of anchor 4.

Progressive Disclosure

The bundle contains no files, and the body's single reference is clearly signaled and one level deep, which is good structure. Minor gaps keep it at anchor 4 rather than 5: the reference targets `~/.agents/skills/handoff/SKILL.md` outside this bundle (unverifiable from the skill itself), and the comment cites `scripts/agent-harnesses.py`, which does not exist in the bundle.

Specificity

Lists several concrete actions — "Create and commit a durable handoff document", "gives a fresh agent the context and prompt to continue the current planning or implementation work" — naming the artifact, the operation (commit), and the contents. Fits anchor 4 ("lists several specific actions; minor gaps in coverage") rather than 5 because coverage stops at create/commit without detail on format or location, and rather than 3 because it goes beyond naming just 1–2 bare actions.

Completeness

Explicitly answers both questions: what ("Create and commit a durable handoff document that gives a fresh agent the context and prompt to continue the current planning or implementation work") and when ("Use only when explicitly invoked as `$handoff` or when the user explicitly requests a handoff") with concrete trigger phrases. This mirrors the anchor-5 example structure exactly; a 4 would require the 'when' to be less explicit, which it is not.

Trigger Term Quality

Good keyword coverage with the natural term "handoff" appearing three times plus the literal invocation token "$handoff" and the phrase "explicitly requests a handoff". It is not 5 because common variations users might say ("hand off", "pass off the work", "transfer context", "continue where you left off") are missing; it is above 3 because the core natural terms are present and repeated.

Distinctiveness Conflict Risk

"Handoff" is a clear niche with distinct triggers, and the restrictive gating ("Use only when explicitly invoked as `$handoff` or when the user explicitly requests a handoff", reinforced by disable-model-invocation) makes accidental triggering for the wrong skill essentially impossible. Minimal conflict risk, matching anchor 5.
