Agent-Driven Codebase Sweep to Plan Flag Removals

An agent crawls the repository for every feature-flag reference, cross-checks each against rollout state, and produces a prioritized removal plan with per-flag risk notes.

What it does

Uses an agent to perform a holistic sweep: it reads the actual code around each flag usage, understands whether the disabled branch still contains logic worth preserving, correlates that with rollout data, and writes a reasoned removal plan ranking flags by safety and effort rather than age alone.

When to use it

Reach for this before a dedicated debt-burndown sprint, when a simple age query is too blunt. The agent distinguishes a flag wrapping a trivial UI toggle from one gating a risky data-migration path, so the team starts with the genuinely safe wins. Run it quarterly or ahead of a major refactor.

How it works

  1. 1Triggered manually when the team kicks off a cleanup initiative.
  2. 2The agent scans GitLab repository contents for all flag-key references and their surrounding code.
  3. 3It queries Postgres rollout state to label each flag fully-on, partial, or dormant.
  4. 4The agent reasons per flag about removal risk, dead-branch contents, and effort.
  5. 5It writes a prioritized removal plan to a Confluence page with risk notes and ordering.
  6. 6It posts a Slack summary linking the plan and highlighting the top safe removals.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect GitLabRepos, MRs, pipelines, registry.
  2. 2
    Connect PostgresAny Postgres URL — query, write, migrate.
  3. 3
    Connect ConfluenceSpaces, pages, blueprints.
  4. 4
    Connect SlackChannels, DMs, threads, mentions.
  5. 5
    Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
  6. 6
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  7. 7
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
