Conciseness

Lean and efficient with no padding and no explanations of concepts Claude already knows; every line is a directive ('take the last one lexicographically, read only that file', 'trim to 10 entries'). Assumes Claude's competence throughout.

Actionability

As an instruction-only skill it needs no code, and its guidance is fully concrete: deterministic handoff selection ('last one lexicographically'), explicit staleness criteria ('timestamps weeks old, references missing files'), a one-line-per-item brief format, and a precise UML.md update procedure. Covers both the full-resume and quick catch-up modes.

Workflow Clarity

Clear numbered 1-6 sequence with explicit branching ('If handoffs/ exists', 'or "nothing in progress"'), a well-defined mode split (catch-up = steps 1-4), and validation checkpoints (staleness check, 'If UML.md contradicts the code, fix it in the same turn'). No destructive/batch operations lacking validation.

Progressive Disclosure

At ~45 lines with no need for external references, the skill qualifies for the simple-skill exception: well-organized sections (Steps, Quick catch-up mode, When work is finished) with no inlined content that belongs in separate files and no nested references.

Specificity

Lists several concrete actions ('Reads the latest handoff (if any), then UML.md', 'gives the user a fast on-ramp', 'handles quick catch-ups'), though 'fast on-ramp' is vague and coverage of the skill's full behavior (resume brief, UML.md upkeep) is incomplete. Not 5 because coverage has minor gaps; not 3 because it goes beyond 1-2 actions.

Completeness

Has a clear 'what' ('Reads the latest handoff (if any), then UML.md, and gives the user a fast on-ramp') but no explicit 'Use when...' clause; the primary 'when' is only weakly implied by 'Resume work in an existing project'. Per the guideline, missing explicit trigger guidance caps completeness at 3 — the only concrete trigger ('what was I doing?') covers the secondary catch-up mode, not the main use case.

Trigger Term Quality

Includes natural phrases users would say ('Resume work', 'quick catch-ups', 'what was I doing?'), giving good keyword coverage. Not 5 because common variations like 'where did I leave off?', 'catch me up', or 'continue where I stopped' are missing.

Distinctiveness Conflict Risk

Occupies a clear niche (resuming existing project work) anchored on distinctive artifacts ('handoff', 'UML.md') and a distinctive trigger phrase ('what was I doing?'). Minimal conflict risk — few skills would trigger on these terms.
