neki

Guidance for Neki, PlanetScale's distributed (sharded) Postgres. Load when working with a Neki database — connecting, data topology and shard keys, query routing and fanout, cross-shard transactions, schema changes, resharding and migration, NK013 errors — or when scaling and sharding Postgres.

Content

80%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

An exemplary overview-style skill: token-efficient, dense with non-obvious product-specific facts, and well-structured progressive disclosure with a complete, verifiable reference bundle. The main gaps are the absence of a runnable connection example and of inline validation checkpoints for the destructive operations (schema changes, resharding) it routes to.

Suggestions

Add a minimal executable connection example (e.g., a psql or psycopg connection string using port 5432 and sslmode=verify-full) so the connecting guidance is copy-paste ready.

Include a brief inline validate-before-proceeding pattern for destructive or batch operations (e.g., run EXPLAIN (NEKI_PLAN) and confirm targeting with SHOW before cross-shard DDL, resharding, or VACUUM) instead of only hazard warnings.

Point reference links at relative bundle paths (references/*.md) rather than remote raw.githubusercontent.com URLs so the locally shipped files resolve directly.

DimensionReasoningScore

Conciseness

A lean ~70-line overview where every fact is Neki-specific and non-obvious (no separate pooler port, typo'd __neki.* settings silently accepted, cross-shard snapshot caveat, VACUUM running on every shard); it assumes Claude's competence and explains nothing Claude already knows.

5 / 5

Actionability

Provides concrete, executable specifics — port 5432 with sslmode=verify-full, the exact session-setting names, EXPLAIN (NEKI_PLAN), SHOW-based verification — but lacks a complete copy-paste example such as a full connection string, leaving minor gaps.

4 / 5

Workflow Clarity

The body is a navigation overview with one good verification checkpoint ('Confirm with SHOW on the real name', 'set them before BEGIN'), but destructive/batch operations it introduces (schema changes, resharding, VACUUM across shards) have no inline validation steps; per the rubric cap this holds at 3.

3 / 5

Progressive Disclosure

Clear overview with 19 one-level-deep references, all of which exist in the local bundle, each with a per-row 'Use for' criterion making navigation easy; the only nit is that link hrefs point to remote raw GitHub URLs rather than relative paths, but link text matches the local references/*.md paths.

Description

91%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong description: it states what the skill covers, gives an explicit load trigger with concrete topic keywords, and includes synonyms and a product-specific error code. The only weaknesses are topic-noun framing instead of action verbs and a broad 'scaling and sharding Postgres' trigger that slightly widens conflict risk.

DimensionReasoningScore

Specificity

Enumerates specific concrete areas (connecting, shard keys, query routing and fanout, cross-shard transactions, schema changes, resharding and migration, NK013 errors), but the 'Guidance for...' framing names topic areas rather than action verbs, leaving a minor gap versus the comprehensive action-phrased anchor.

4 / 5

Completeness

Explicitly answers both: what ('Guidance for Neki, PlanetScale's distributed (sharded) Postgres') and when ('Load when working with a Neki database — ... — or when scaling and sharding Postgres') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Covers natural terms users would say with synonyms: 'Neki database', 'distributed (sharded) Postgres', 'shard keys', 'resharding and migration', 'scaling and sharding Postgres', plus the specific error keyword 'NK013' — comprehensive synonym coverage with no common variation obviously missing.

5 / 5

Distinctiveness Conflict Risk

Clear niche around a named PlanetScale product with distinct triggers, but the broad tail trigger 'or when scaling and sharding Postgres' creates minor overlap risk with a general Postgres or sharding skill.
