setting-up-a-data-warehouse-source

Guide the user through connecting a new data warehouse source — Postgres, MySQL, Stripe, Hubspot, MongoDB, Salesforce, BigQuery, Snowflake, and so on. Use when the user wants to "connect Stripe", "import data from Postgres", "add a new data source", "sync my warehouse tables", or wants to pick sync methods for each table. Walks through source-type discovery, credential validation, table discovery, per-table sync_type selection, and the final create call. Also covers picking a good prefix and what to do right after creation.

Quality

Content

77%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 with a well-sequenced, validation-backed workflow and concrete tool calls and payloads. Its weak spots are conciseness (a redundant Important notes section) and progressive disclosure (a referenced sync-types.md file that is missing from the bundle).

Suggestions

Remove or fold the "Important notes" section into the relevant workflow steps — it re-states webhook/prefix/connect-link/validate-before-create guidance already covered above.

Create the referenced `./references/sync-types.md` (currently absent) or inline its full sync-type decision rules so the dangling link does not break navigation.

Tighten the Pre-flight credential-gotchas list by moving per-source key-type trivia (Resend, Mailgun, RevenueCat, etc.) into a reference file, keeping only the highest-impact gotchas inline.

DimensionReasoningScore

Conciseness

Most content is operational and tool-specific (credential gotchas, webhook flow) and earns its place, but the "Important notes" section restates webhook-as-separate-step, prefix-is-load-bearing, prefer-connect-link, and validate-before-create guidance already detailed in the workflow steps, adding noticeable repetition.

3 / 5

Actionability

Provides named tool calls with parameters (e.g. `external-data-sources-db-schema`, `data-warehouse-source-setup({source_type, payload, prefix})`), a complete copy-paste JSON payload, and concrete error-recovery steps (show 400 message verbatim, manual webhook registration) covering the common cases.

5 / 5

Workflow Clarity

A clearly sequenced Steps 1–7 workflow plus explicit validation checkpoints (db-schema validates creds before create, present table list and confirm prefix before creating, webhook-info-retrieve verification) and feedback loops for error recovery; validation is present so the batch/destructive cap does not apply.

5 / 5

Progressive Disclosure

Sections are well organized and the sync-type guide is clearly signaled via a named markdown link, but the only bundle reference `./references/sync-types.md` points to a file that does not exist (no references/ directory), leaving a broken navigation target and the detailed sync-type rules only partially inlined.

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.

A strong, third-person description that names concrete workflow steps, lists many natural trigger phrases, and explicitly covers both what the skill does and when to use it. It is specific to PostHog's data warehouse tooling, so conflict risk is minimal.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — "source-type discovery, credential validation, table discovery, per-table sync_type selection, and the final create call" plus prefix picking and post-creation guidance — giving comprehensive coverage of the workflow rather than vague language.

5 / 5

Completeness

Explicitly answers both what ("Walks through source-type discovery, credential validation, table discovery, per-table sync_type selection, and the final create call") and when ("Use when the user wants to 'connect Stripe'...") with concrete trigger phrases.

5 / 5

Trigger Term Quality

Embeds natural phrases users actually say ("connect Stripe", "import data from Postgres", "add a new data source", "sync my warehouse tables") alongside a broad list of concrete source-type names, giving comprehensive trigger coverage.

5 / 5

Distinctiveness Conflict Risk

The niche is tightly scoped to PostHog data-warehouse source setup with named tools and source types, making it clearly distinguishable from other skills with minimal overlap risk.
