Conciseness

The ~15-line body is lean and assumes Claude's competence; every sentence instructs (write summary, save to temp dir, launch command, name it, include suggested skills, reference artifacts by path, strip secrets, honor arguments). The only rationale sentences — the shell-quoting pitfall for backticks/`$` and the `--name` display-name explanation — cover genuinely non-obvious pitfalls, so every token earns its place (anchor 5).

Actionability

The core command is concrete and executable — `claude --bg --name "<descriptive name>" -- "$(cat <summary file>)"` — with a worked example (`--name "Fix login bug"`) and specific instructions for summary content, matching anchor 4's 'mostly executable guidance with minor gaps'. It falls short of 5 because `<summary file>` and `<descriptive name>` remain unfilled placeholders with no concrete example of creating the temp file (e.g., a `mktemp`-style invocation or example path).

Workflow Clarity

The sequence — write handoff summary, save to temp dir, launch background agent, user manages via `claude agents` — is clear and unambiguous for a simple, non-destructive single-purpose skill, matching anchor 4. It is not 5 because there are no checkpoints at all (e.g., verifying the summary file was written or the agent actually launched), and not 3 because the single action is unambiguous and no validation-sensitive operation is involved.

Progressive Disclosure

The skill is under 50 lines, needs no external references, and is organized as one focused paragraph per instruction with no inlined material that belongs elsewhere. Per the simple-skill guidance, this earns anchor 5 on well-organized sections alone.

Specificity

The description names one concrete action — "把当前对话交接给一个全新的 background agent，让它立即接手工作" (hand off the current conversation to a new background agent that immediately takes over) — matching anchor 3's '1-2 concrete actions, not comprehensive'. It stays at 3 rather than 4 because it lists only this single action with no detail on what the handoff involves (summary writing, temp file, background launch).

Completeness

The 'what' is clear (hand the current conversation to a new background agent), but the 'when' is entirely absent — there is no 'Use when...' clause or equivalent, which caps completeness at 3 per the judging guidelines. Not 2 because the 'what' is concrete, not vague.

Trigger Term Quality

"交接" (hand off) is a relevant, natural keyword a user might say, fitting anchor 3's 'some relevant keywords but missing common variations or synonyms' — synonyms like 'handoff', 'continue', 'spawn', or 'take over' are absent and no trigger phrasing is offered. It scores above 2 because the keyword is specific rather than generic like 'works with files'.

Distinctiveness Conflict Risk

Conversation handoff to a background agent is a distinct niche with little overlap risk against typical skills, fitting anchor 4's 'mostly distinct; minor overlap risk'. It falls short of 5 only because the description's terseness leaves it slightly ambiguous against generic agent-spawning or session-management skills.
