Architecture Decision Records

Architecture Decision Records (ADRs) preserve important design choices and their tradeoffs. Atlantis adopted them in ADR 0001.

Index

ADR Title Status
0001 Record architecture decisions Accepted
0002 API Enhancement and Drift Detection Proposed

Update this table when adding or changing an ADR.

Which process should I use?

Change Process
Bug fixes, docs, tests, CI, dependency updates, and behavior-preserving refactors Open a pull request.
New user-visible behavior, flags, or commands Agree on the change in an issue, then open a pull request.
A change matching the criteria below Open an issue, submit an ADR, then implement it after the ADR is accepted.

The decision matters more than the diff size.

When is an ADR required?

Write an ADR when a change:

  • changes persisted data, migrations, or on-disk layout;
  • makes a breaking change to an API, config schema, server flag, default, or webhook contract;
  • changes concurrency or locking behavior;
  • adds a required runtime service, plugin, or extension point;
  • changes authentication, authorization, secret handling, command execution, or webhook validation;
  • is irreversible or reverses an accepted ADR.

An ADR is not required for bug fixes, additive optional fields, default-off features, performance work with unchanged behavior, refactors, tests, docs, tooling, CI, or dependency updates.

If unsure, open an issue before starting a large implementation.

Submit an ADR

  1. Agree on the problem in an issue.
  2. Copy template.md to docs/adr/NNNN-short-title.md.
  3. Use the next number across merged ADRs and open ADR pull requests. Renumber if another ADR merges first.
  4. Open a pull request with status Proposed and update the index above.

Keep the ADR focused on one decision. Put implementation details in the issue or implementation pull request.

Statuses

  • Proposed: under discussion.
  • Accepted: approved by the project.
  • Rejected: considered and declined.
  • Superseded by NNNN: replaced by a later ADR.
  • Deprecated: no longer applies.

Merge accepted and rejected ADRs so both decisions remain discoverable. Do not rewrite them later; supersede them with a new ADR.

ADRs follow normal pull request review rules. Link accepted ADRs from their implementation pull requests.
