When those engineers leave, move to different teams, or simply forget the reasoning two years later, the team inherits constraints they cannot explain, which leads to one of two failure modes: either the decision is blindly followed when it should have been revisited, or it is reversed without understanding the original trade-offs it was managing.<\/p>\n\n\n\n<p>A standard ADR contains six sections:<\/p>\n\n\n\n<ul>\n<li><strong>Title<\/strong>: Short, present-tense description of the decision<\/li>\n\n\n\n<li><strong>Status<\/strong>: Proposed, Accepted, Deprecated, or Superseded<\/li>\n\n\n\n<li><strong>Context<\/strong>: The situation or problem that required a decision<\/li>\n\n\n\n<li><strong>Decision<\/strong>: What was decided and why<\/li>\n\n\n\n<li><strong>Consequences<\/strong>: What this makes easier, harder, or different<\/li>\n\n\n\n<li><strong>Alternatives Considered<\/strong>: What else was evaluated and why it was not chosen<\/li>\n<\/ul>\n\n\n\n<p><strong>Read More: <\/strong><a href=\"https:\/\/www.guvi.in\/blog\/claude-code-tips-and-best-practices\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>50 Claude Code Tips and Best Practices For Daily Use<\/strong><\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Generating a New ADR with Claude<\/strong><\/h2>\n\n\n\n<p>The fastest path to a complete ADR is giving Claude the raw decision context in bullet form and letting it produce the structured document.

Claude can extract and structure ADRs from these informal records.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>Extract and write an Architecture Decision Record from these\nmeeting notes or discussion thread.\n\nSource: &#91;Meeting notes \/ Slack thread \/ design review comments]\nSystem or component affected: &#91;What part of the architecture this covers]\n\nNotes or thread:\n&#91;paste meeting notes or Slack thread here]\n\nIdentify:\n1. What decision was made (explicit or implied)\n2. What context or problem prompted the discussion\n3. What alternatives were discussed or rejected\n4.

Despite a decade of industry endorsement, adoption remains low because writing overhead feels too high, a perception that changes immediately when new engineers can answer architecture questions from ADRs instead of interrupting senior engineers.\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Updating and Superseding Existing ADRs<\/strong><\/h2>\n\n\n\n<p>ADRs should never be edited after acceptance. When a decision changes, a new ADR is written that supersedes the old one, with a link between them. Claude handles this update pattern cleanly.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>Write a new ADR that supersedes an existing decision.\n\nOriginal ADR title and summary: &#91;paste or describe the original ADR]\nReason the original decision is being revisited: &#91;What changed to make\nthe original decision no longer appropriate: new requirements, scale,\ntechnology availability, or lessons learned]\n\nNew decision: &#91;What is being decided now]\nKey differences from the original decision: &#91;What changed and why]\nConsequences of this change: &#91;What needs to be updated, migrated, or communicated]\n\nFormat the new ADR with:\n- Status: Accepted (Supersedes ADR-&#91;number])\n- A Context section that references the original decision and explains\n  why it is being revisited\n- The full standard ADR structure for the new decision\n\nAlso write a one-line update to add to the original ADR's Status field:\n\"Superseded by ADR-&#91;new number] on &#91;date] because &#91;reason in one sentence]\"<\/code><\/pre>\n\n\n\n<div style=\"background-color: #099f4e; border: 3px solid #110053; border-radius: 12px; padding: 18px 22px; color: #FFFFFF; font-size: 18px; font-family: Montserrat, Helvetica, sans-serif; line-height: 1.6; box-shadow: 0 4px 12px rgba(0, 0, 0, 0.15); max-width: 750px;\">\n\n  <strong style=\"font-size: 22px; color: #FFFFFF;\">\ud83d\udca1 Did You Know?<\/strong>\n  <br \/><br \/>\n\n  <strong style=\"color: #FFFFFF;\">Michael Nygard estimated that writing a complete ADR takes 30 to 60 minutes for a decision the team already understands.
