Atlan SQL Connector Patterns

VerifiedSafe

Select and apply the correct SQL connector implementation pattern (SDK-default minimal or source-specific custom) for building or extending SQL metadata/query extraction connectors. Helps developers choose between minimal and custom paths based on a decision tree, ensuring consistent implementation of authentication, preflight, workflow map, and transformation behavior.

Automated summary

Select and implement the appropriate SQL connector pattern (minimal SDK or custom source-specific) for metadata extraction.

Strengths

  • Structured guide with decision tree to choose between minimal and custom paths
  • Reuses verified components and shared references
  • Integrates downstream fact verification and contract validation

Limitations

  • Requires external references (decision tree, verification sources)
  • Specific to the Atlan ecosystem and its associated tools
  • Covers only SQL connectors, not other types
When to use it

When building or extending a SQL metadata extraction connector and deciding between a minimal SDK or custom implementation.

When not to use it

If working on non-SQL connectors or if the required decision references are unavailable.

Security analysis

Safe
Quality score85/100

The skill is a high-level decision guide for selecting SQL connector patterns and does not instruct execution of any commands or tools that could compromise security. It references other verification components but contains no dangerous or obfuscated instructions.

How this analysis is made

Examples

Choose connector strategy for Redshift
I need to build a SQL connector for Redshift. Should I use the minimal SDK path or a custom source-specific pattern? Follow the decision tree and implement accordingly.
Implement minimal Postgres connector
Implement a minimal SQL connector for Postgres using the SDK-default approach. Use the decision tree to confirm and verify with the fact verification gate.
Document custom connector justification
I am implementing a custom SQL connector for Redshift. Help me document why SDK defaults are insufficient and verify the requirements against the shared verification sources.

Atlan SQL Connector Patterns

Choose the right connector strategy and implement it consistently.

Workflow

  1. Use references/decision-tree.md to choose postgres-minimal or redshift-custom.
  2. Implement required components for selected path.
  3. Verify auth, preflight, workflow map, and transformation behavior against references.
  4. Run atlan-fact-verification-gate if requirements imply source-specific behavior or SDK override risk.
  5. Hand off to atlan-e2e-contract-validator for contract generation.

Rules

  • Default to minimal path unless requirements justify custom path.
  • For custom path, explicitly document why SDK defaults are insufficient.
  • Reuse source-specific patterns only when corresponding requirements are present.

References

  • Decision tree: references/decision-tree.md
  • Shared verification map: ../_shared/references/verification-sources.md

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/atlan-sql-connector-patterns-mm8o517i/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/atlan-sql-connector-patterns-mm8o517i' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/atlan-sql-connector-patterns-mm8o517i/download' --output '.skill-downloads/atlan-sql-connector-patterns-mm8o517i/SKILL.md.part' && mv '.skill-downloads/atlan-sql-connector-patterns-mm8o517i/SKILL.md.part' '.skill-downloads/atlan-sql-connector-patterns-mm8o517i/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

Claude Code
test -f '.skill-downloads/atlan-sql-connector-patterns-mm8o517i/SKILL.md' && test -s '.skill-downloads/atlan-sql-connector-patterns-mm8o517i/SKILL.md' && mkdir -p '.claude/skills' && test ! -e '.claude/skills/atlan-sql-connector-patterns' && cp -R '.skill-downloads/atlan-sql-connector-patterns-mm8o517i' '.claude/skills/atlan-sql-connector-patterns'

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation
openskills install './.skill-downloads/atlan-sql-connector-patterns-mm8o517i'

openskills read 'atlan-sql-connector-patterns-mm8o517i'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/atlan-sql-connector-patterns-mm8o517i/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
