Conciseness

The body is directive throughout — exact commands, path patterns, and rejection rules with no concept explanations Claude already knows — matching 'Efficient; minor instances of over-explanation that could be trimmed'. It is not a 5 because the execution-contract section repeats similar prohibitions ("Do not expose raw internal state..." later re-echoed by layout/stop rules in each path) that could be tightened; it is clearly above a 3 with only minor trimming opportunities.

Actionability

Guidance is fully executable for an instruction-only skill: exact git commands (`git status`, `git diff`, `git diff --cached`), concrete path resolution rules with a worked example (`context/handovers/{plan_name}-{task_id}.md`, `T01`), a timestamped fallback format, explicit loader rejection criteria, and named output layouts. This matches 'concrete code or commands; specific examples cover the common cases' — the top anchor; the only mild spot ("Recent commits") is minor and not enough to drop to 4.

Workflow Clarity

Both paths are clearly sequenced with explicit validation checkpoints: writer step 5 validates the written file against the template's Completeness contract before reporting success, loader steps 1-2 validate the path and completeness, and error recovery is specified (never overwrite; fall back to a timestamped name, or render the blocked layout and stop). This matches the anchor 'Clear sequence with explicit validation steps; feedback loops for error recovery'.

Progressive Disclosure

The SKILL.md is a clear overview that appropriately delegates the persisted schema to `references/handover-template.md` and terminal layouts to `references/output.md` — both real files, clearly signaled, one level deep (the template's mention of output.md stays within the same bundle). Content is appropriately split with easy navigation, matching the top anchor.

Specificity

"Write a session handover document, or load one for continuation" names the domain and exactly two concrete actions (write, load), matching the anchor 'Names domain and 1-2 concrete actions, but not comprehensive'. It is not a 4 because no further specific capabilities are listed (e.g., composing from session/repository facts, validating against a template).

Completeness

The 'what' is clear (write or load a session handover document) but there is no 'when' — no 'Use when...' clause or equivalent trigger guidance, which per the judging guidelines caps completeness at 3. It has a clear 'what' with 'when' missing entirely, the exact anchor-3 example.

Trigger Term Quality

Relevant keywords are present ("session handover", "handover document", "continuation") but common variations and synonyms users naturally say are missing — e.g., "handoff", "resume", "pick up where the last session left off". This matches 'Some relevant keywords but missing common variations or synonyms', not the good coverage of a 4.

Distinctiveness Conflict Risk

"Session handover" is a fairly specific niche with minimal overlap risk against typical skills, matching 'Mostly distinct; minor overlap risk'. It is not a 5 because the description gives no explicit trigger phrases, so it is not fully distinguishable from adjacent skills like session summarization; it is clearly above a 3 since the domain is not generic.
