At a glance

Stands up a throwaway local SQL Server 2022 backend, applies SQL fixtures and runs Airbyte spec, check, discover and read against source-mssql images.

  • Reproducing a non-CDC source-mssql bug against a local SQL Server
  • SKILL.md covers When to use this skill, Prerequisites, Layout and Conventions, plus 4 more sections
  • Runs Shell scripts from its folder; calls jq, docker and uv
  • Running spec, check, discover and read against a specific connector image tag

What it does

This is a local end-to-end harness for the Airbyte source-mssql connector. It starts a SQL Server 2022 container named source-mssql-db-backend, applies SQL fixtures you supply, and runs the protocol commands spec, check, discover and read against any airbyte/source-mssql image tag through the airbyte-ops regression-test command. Engine-independent orchestration lives in a shared db-harness-lib folder, while this skill keeps the backend scripts, fixtures and config templates.

Output goes under a working directory, /tmp/source-mssql-repro by default, with the rendered config.json, a derived configured_catalog.json and one folder per command holding stdout, stderr and report files in Markdown and HTML. It is for non-CDC reproductions and serves as the base for a separate CDC skill. Docker, uv with airbyte-internal-ops, jq and a clone of the airbyte repository are needed, but no GSM or Cloud admin credentials.

When your agent uses it

  • Reproducing a non-CDC source-mssql bug against a local SQL Server
  • Running spec, check, discover and read against a specific connector image tag
  • Testing connector behavior against custom SQL fixtures

Example prompts

  • “Start a local SQL Server and run the full spec, check, discover and read sweep against the dev tag of source-mssql.”
  • “Apply my fixture file with the sample tables and rerun only discover.”
  • “Reset the databases and reproduce the failing read from this bug report.”

Requirements

  • Docker
  • uv, with airbyte-internal-ops installed
  • jq
  • A clone of the airbytehq/airbyte repository

What it can do on your machine

Read from SKILL.md and the folder at commit 38c668c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 4 files in scripts/ (Shell), which the agent can run.

    Shell commands in SKILL.md call:

    • jq
    • docker
    • uv
    • uvx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • docs.astral.sh
    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

source-mssql E2E Test Harness loads about 4.4k tokens when it runs. Until then it costs about 87 tokens; SKILL.md has 1,609 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~87
When it runs · the whole SKILL.md, loaded when a task matches
~4.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,609 words (~4,359 tokens).

“Local end-to-end test harness for source-mssql. The engine-independent orchestration lives in airbyte-integrations/db-harness-lib/; this skill keeps the MSSQL backend lifecycle scripts, fixtures, and config templates. It stands up a SQL Server 2022 container named source-mssql-db-backend, lets you apply arbitrary SQL fixtures…”
