    data-pipeline-design

    Design batch or incremental ETL and ELT pipelines and warehouse models: grain, partitioning, idempotent loads, late-arriving data, data quality tests, PII controls, and cost monitoring, before building them. Use when adding or changing a dbt model, warehouse table, scheduled transformation, or ingestion job. Not for transactional schema design (use the database-design skill) or event-sourced stores (use the event-sourcing-architecture skill).

    third-party-integration

    Use when integrating with external APIs, payment processors (Stripe), webhooks, or third-party services. Use when implementing API clients with authentication and rate limiting, handling webhooks with signature verification and idempotency, writing contract tests for external services, or isolating third-party dependencies behind adapters. Triggers: \"Stripe\", \"payment integration\", \"webhook\", \"third-party API\", \"external service\", \"API client\", \"integrate with\", \"signature verification\", \"idempotency key\".

The file

We split this skill into the rules it gives an agent

2 rules. 0 are common, 2 are distinctive, and 0 are very specific to this project.

  • 0

    Common

    Most of the 165 edited versions we read keep these.

  • 2

    Distinctive

    This author's own choices. Worth a look.

  • 0

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    Use stable field names; avoid cryptic abbreviations.

    line 19
  2. Distinctive:

    Prefer additive fields over renames/removals.

    line 21

“Common” is measured: kept by at least 6 in 10 of the 165 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

API Design

Defaults

  • Clear resource nouns; HTTP methods match semantics.
  • Consistent naming, pagination, filtering, and error shape.
  • Explicit auth requirements per endpoint.
  • Idempotent writes where clients may retry (PUT/DELETE or idempotency keys).
  • Backward-compatible changes when consumers exist.

Request/Response

  • Validate inputs at the boundary; reject with actionable errors.
  • Use stable field names; avoid cryptic abbreviations.
  • Return sufficient IDs for follow-up calls.
  • Prefer additive fields over renames/removals.

Breaking Changes

Require a version strategy or coordinated migration when removing fields, changing types, or altering auth semantics.

Checklist

  • AuthZ defined
  • Error codes documented
  • Pagination/limits on lists
  • No sensitive data in URLs/logs
  • Compatibility impact stated

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
