AI & RAG

Ask 'why is this config set this way?' in Slack, answered from Git + ADRs

An operator asks why a setting has its current value in a Slack channel, and a RAG agent answers with the rationale traced from the commit that introduced it and any linked ADR.

What it does

Lets engineers ask plain-English questions like "why is the connection pool capped at 20?" in Slack and get a grounded answer that traces the value back to the commit that set it and the architecture decision record (ADR) that justified it. Every answer cites a commit SHA and, where one exists, an ADR ID and link.

When to use it

When tribal knowledge about config keeps getting lost, new hires keep asking "who set this and why," or a value looks wrong and someone needs the original reasoning before changing it. Best for teams keeping ADRs in Confluence and config in GitLab.

How it works

  1. 1A Slack slash command or mention captures the config question and the file or key in question.
  2. 2The agent runs `git log -p` / blame against the GitLab repo to find the commit that last changed that line and its message body.
  3. 3It searches Confluence ADRs for terms from the commit message and the config key.
  4. 4It synthesizes the rationale, grounding the answer in the retrieved commit and ADR text only.
  5. 5It replies in-thread with the explanation plus cited SHA and ADR link.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect SlackChannels, DMs, threads, mentions.
  2. 2
    Connect GitLabRepos, MRs, pipelines, registry.
  3. 3
    Connect ConfluenceSpaces, pages, blueprints.
  4. 4
    Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
  5. 5
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  6. 6
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
