Conciseness

The body is dense with practitioner-specific value (buffer zones at 33/67%, drum at >85% utilization, 4-hour stability lock, 30-minute communication window), but several Core Knowledge blocks re-explain concepts Claude already knows: the OEE formula, SMED's four phases, heijunka sequencing, forward vs. backward scheduling, and DBR basics. This matches anchor 3 ('mostly efficient but includes some unnecessary explanation or could be tightened') — not 2, because most explanations embed scheduling-specific judgment rather than being pure textbook padding.

Actionability

For an instruction-only skill, the guidance is fully concrete and executable: a decision tree with named dispatching rules and a numeric swap threshold ("setup-aware EDD... swaps adjacent jobs when a swap saves >30 minutes of setup"), quantified examples (campaign vs. mixed-model crossover, $5,000/hour cross-training ROI), numbered procedures, an escalation table with timelines, and metrics with numeric targets and red flags. This matches anchor 5's 'specific examples cover the common cases'.

Workflow Clarity

Multi-step processes are clearly sequenced with explicit validation checkpoints: "Verify causally: Would adding one hour of capacity at this work centre increase total plant output?", "Validate against due dates: Run the optimized sequence through the schedule", and a feedback loop in 'Closing the loop' (compare scheduled vs. actual each shift, rolling re-plan). The disruption workflow adds freeze windows and a stability lock — a direct match for anchor 5's 'explicit validation steps; feedback loops'.

Progressive Disclosure

The body is well-organized with clear section headers, but it is a ~238-line, 28KB monolith with zero reference files: content that clearly belongs in separate files (the escalation trigger table, communication templates, the eight edge cases, and the Core Knowledge framework explanations) is inlined. This matches anchor 3 ('some structure... content that should be separate is inline'); not 4, because with no bundle files at all, most content is not 'appropriately placed' for a skill this size.

Specificity

The description lists multiple specific concrete capabilities — "production scheduling, job sequencing, line balancing, changeover optimization, and bottleneck resolution" — and names concrete frameworks (TOC/drum-buffer-rope, SMED, OEE analysis, ERP/MES interaction patterns) with comprehensive coverage of the domain. The credential line ('Informed by production schedulers with 15+ years experience') is padding but does not create coverage gaps, so this fits the 5 anchor rather than the 4 anchor's 'minor gaps'.

Completeness

It explicitly answers both 'what' ("Codified expertise for production scheduling... Includes TOC/drum-buffer-rope, SMED, OEE analysis...") and 'when' ("Use when scheduling production, resolving bottlenecks, optimizing changeovers...") with concrete trigger phrases — a direct match for the anchor 5 example pattern. Not 4, because the 'when' clause is explicit and enumerated rather than merely present.

Trigger Term Quality

The 'Use when' clause covers natural phrases users would say: "scheduling production, resolving bottlenecks, optimizing changeovers, responding to disruptions, or balancing manufacturing lines". However, common variations like capacity planning, throughput, hot/rush orders, or expediting are missing, matching anchor 4 ('good keyword coverage; a few natural terms missing') rather than the comprehensive synonym coverage of anchor 5.

Distinctiveness Conflict Risk

The manufacturing-specific qualifiers ("discrete and batch manufacturing", "production scheduling", "manufacturing lines") establish a clear niche with distinct triggers. The 'production/manufacturing' framing prevents overlap with calendar- or meeting-scheduling skills, so conflict risk is minimal — anchor 5 rather than 4's 'minor overlap risk with closely related skills'.
