Conciseness

Quotes: "LPUSH <key> <val1> [val2...] # Push to head", "ZRANGE <key> <start> <stop> [--withscores] [--rev]...", "Sets store unique, unordered members". The wrapper-specific material (bun invocation, --url/--token override, output format, confirmation policy) earns its place, but roughly 250 of the ~430 lines re-list standard Redis command syntax and data-type explanations Claude already knows, so it is mostly efficient but could be tightened considerably — not anchor 5's every-token-earns-its-place, and not anchor 2 since the script-specific parts are genuinely non-obvious and the listings are terse rather than padded prose.

Actionability

Quotes: "bun run scripts/upstash-client.ts <command> [args...]", "bun run scripts/upstash-client.ts HSET user:1 name "John" email "john@example.com" age 30", "bun run scripts/upstash-client.ts --url "https://..." --token "AX..." GET mykey". Every command family has copy-paste-ready invocations with worked examples covering common cases (queues, tags, leaderboards, session TTL), fully matching the top anchor.

Workflow Clarity

Quotes: "Before executing any destructive operation (write, modify, or delete), you MUST ask the user for confirmation", the YOLO-mode indicators list, and "If credentials are missing or invalid, the script will exit with an error message". The destructive-operation confirmation gate and error path satisfy the validation requirement, so the destructive-skill cap at 3 does not apply, and the single action (run one command) is unambiguous; it falls short of anchor 5 only for lacking a post-write verification step or broader error-recovery feedback loop beyond credentials.

Progressive Disclosure

Quotes: "## Command Reference" followed by ~300 lines of inline command listings, and the repeated "scripts/upstash-client.ts" reference. Section headers are clear and the layout is scannable, but the bulk command reference is exactly the content the rubric says belongs in a separate file, no references/ files exist, and the one path the body depends on (scripts/upstash-client.ts) is absent from the bundle (no scripts/ directory present) — matching anchor 3's 'content that should be separate is inline' rather than anchor 4's appropriately split structure, though the internal organization is too good for anchor 2's 'minimal structure'.

Specificity

Quotes: "Read and write to Upstash Redis-compatible key-value store via REST API" names the domain and two concrete actions, and "use Redis features (caching, counters, lists, sets, hashes, sorted sets, etc.)" enumerates breadth. It lists several specific actions with minor gaps, but the actual verbs are limited to read/write/save/retrieve rather than the fuller action coverage of the top anchor, so it sits at 4, not 5, and well above the 1-2-action coverage of anchor 3.

Completeness

Quotes: "Read and write to Upstash Redis-compatible key-value store via REST API" explicitly answers 'what', and "Use when there is a need to save or retrieve key-value data... or when the user explicitly asks to use Upstash or Redis" explicitly answers 'when' with concrete trigger phrases, matching the top anchor exactly rather than the weaker 'when' of anchor 4.

Trigger Term Quality

Quotes: "save or retrieve key-value data", "use Redis features (caching, counters, lists, sets, hashes, sorted sets, etc.)", "use Upstash or Redis". These are natural phrases a user would say, with synonyms (read/write, save/retrieve) and both brand names (Upstash, Redis) covered; no file extensions apply to this domain, so coverage is comprehensive at 5 rather than the few-terms-missing level of 4.

Distinctiveness Conflict Risk

Quotes: "Upstash Redis-compatible key-value store via REST API" and "use Upstash or Redis" give it a clear niche distinct from other skills, but "Use when there is a need to save or retrieve key-value data for the current interaction" is broad enough to overlap with generic storage/database skills — minor overlap risk, matching anchor 4 rather than the minimal-conflict anchor 5 or the generic overlap of anchor 3.
