tuning-incremental-sync-config

Change the sync configuration of an existing data warehouse schema — switch sync_type, pick a different incremental_field, set primary_key_columns, choose cdc_table_mode, or change sync_frequency. Use when the user asks "switch my orders table from full refresh to incremental", "this table is syncing too slowly / too frequently", "I need to pick a different incremental column", "set up CDC for this Postgres table", or when diagnosis of a failing sync pointed to an incremental-field or PK misconfiguration.

Quality

Content

88%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.

The body is highly actionable and workflow-safe, with exact tool calls, a clear destructive/non-destructive decision gate, and explicit post-change validation. Its main weakness is minor verbosity and some overlap between the main workflow and the per-change subsections, which keeps conciseness and progressive disclosure at 4 rather than 5.

Suggestions

Trim explanatory asides that restate tool semantics (e.g. 'Even though the operation name says create, it re-reads the source') to lift conciseness toward 5.

Reduce overlap between the main 5-step Workflow and the 'Specific common changes' subsections — reference the shared steps rather than re-listing them, or move the per-change recipes into a separate references file.

Consider splitting the large 'Specific common changes' section (and the full field/value tables) into a referenced file so the SKILL.md body serves as a tighter overview with one-level-deep navigation.

DimensionReasoningScore

Conciseness

Mostly lean and purposeful — tabular field references, terse numbered workflows, and JSON payloads with no padding about what a warehouse or CDC is — but a few explanatory asides ('Even though the operation name says create, it re-reads the source') could be trimmed.

4 / 5

Actionability

Provides exact parameterized tool calls (e.g. external-data-schemas-partial-update({id}, {...changed fields})) and copy-paste-ready JSON payloads covering the common change cases, plus a precise field-value table.

5 / 5

Workflow Clarity

Five-step workflow with explicit validation checkpoints — read-before-write in Step 1, the destructive/non-destructive decision gate in Step 4, and status confirmation (Running then Completed, last_synced_at) in Step 5 — with resync actions gated behind user warnings.

5 / 5

Progressive Disclosure

Well-organized single-file skill with clear section headers and no nested references, but the long 'Specific common changes' section partially reiterates the main workflow and no external references are signaled where the body could be split.

Description

100%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.

The description is exemplary: it states five concrete tuning actions on a named domain, provides multiple natural user-voice trigger phrases, and cleanly separates retuning from initial source setup. It answers both what and when explicitly with minimal conflict risk.

DimensionReasoningScore

Specificity

Names the domain and five distinct concrete actions — 'switch sync_type, pick a different incremental_field, set primary_key_columns, choose cdc_table_mode, or change sync_frequency' — giving comprehensive coverage of the tunable config.

5 / 5

Completeness

Explicitly answers both 'what' (the five config changes) and 'when' via a 'Use when...' clause with concrete trigger phrases, including a diagnosis-triggered case.

5 / 5

Trigger Term Quality

Includes verbatim user-voice phrases such as 'switch my orders table from full refresh to incremental', 'this table is syncing too slowly / too frequently', and 'set up CDC for this Postgres table', covering natural synonyms and variations.

5 / 5

Distinctiveness Conflict Risk

Occupies a clear niche — retuning an existing warehouse schema's sync config — and disambiguates against the sibling setup skill, with triggers specific to retuning rather than creation.
