Conciseness

The body is entirely prescriptive — rules, a six-step workflow, exact commands, and the output template — with zero space spent explaining concepts Claude already knows. Every section ("Act immediately", the one-command git inspection block, the commit commands) earns its tokens; it matches the 'lean and efficient; every token earns its place' anchor rather than the 4 anchor, which expects over-explanation to trim.

Actionability

Guidance is fully executable: a copy-paste git inspection one-liner, an exact output path pattern (`docs/handoffs/YYYY-MM-DD-<topic>.md`), a complete markdown template, and ready commit commands (`git add -- "docs/handoffs/..."`, `git commit -m "docs: Add <topic> handoff"`). This matches the 'copy-paste ready' anchor; not 4 because there are no gaps in the common cases.

Workflow Clarity

The six steps are clearly sequenced with explicit validation and recovery: step 4 reviews the document for completeness and forbids leftover placeholders, and step 5 handles commit failure ("keep the document written, report the failure and exact remediation"), plus the non-git-repository fallback. It matches the anchor with explicit validation steps and feedback loops; not 4 because checkpoints and failure paths are all explicit.

Progressive Disclosure

Good structure (Rules / Workflow / template) with no external files needed, but the ~74-line inline document template is substantial content that could live in a `references/` or `assets/` file to slim the always-loaded SKILL.md. Matches 'good structure; most content appropriately placed; minor organization gaps'; not 5 because the file is over 50 lines and the template is a candidate for one-level-deep extraction, and not 3 because nothing is buried or misfiled.

Specificity

"Create and commit a durable handoff document" names the domain and two concrete actions, matching the anchor for 1-2 concrete actions without comprehensive coverage. Not 4 because it does not enumerate several specific actions (e.g., what the document contains or how it is structured); not 2 because the actions are concrete rather than generic.

Completeness

The description explicitly answers both: 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. Not 4 because the 'when' clause is already fully explicit rather than needing more specificity.

Trigger Term Quality

"handoff" (and "$handoff") is the single natural keyword a user would say, but common variations like "hand over", "session summary", or "continue where you left off" are absent. Not 4 because coverage is limited to one term family; not 2 because that term is directly relevant and naturally spoken.

Distinctiveness Conflict Risk

"Use only when explicitly invoked as `$handoff` or when the user explicitly requests a handoff" carves out a clear niche with distinct triggers and very low risk of firing for unrelated skills. Not 4 because the explicit-invocation restriction leaves almost no overlap risk with summarization or documentation skills.
