ABOUTME: Full ADR lifecycle: Linear ticket, branch, write, vault, review, commit, PR

ABOUTME: Follows HikmaAI format and ADR guidelines (Linear ticket = ADR number)

Architecture Decision Records

Quality Notes

• Take your time with research before writing
• ADRs are permanent records; accuracy matters more than speed
• Every claim should be backed by evidence (code, docs, benchmarks)
• Do not skip the refinement step for ambiguous topics

Workflow

Step 1: Refine Requirements

Before writing, clarify scope using AskUserQuestion:

• What decision is being made? (single clear question)
• What options are on the table?
• What constraints apply?
• Who are the stakeholders?

Skip if user provided a fully specified request or said "just write it."

Step 2: Research

Launch research-analyst agent to gather:

• Prior art (existing ADRs in vault, LEARNING.md, MEMORY.md)
• External references (competing approaches, industry patterns)
• Current codebase state (relevant files, existing patterns)

For HikmaAI projects, always check:

• Vault: Projects/HikmaAI/HLD/ for existing ADRs
• CLAUDE.md for architecture context
• Relevant source code for current implementation

Step 3: Create Linear Ticket (reserves the ADR number)

The Linear ticket number IS the ADR number. No separate counter. Gaps in numbering are expected.

Before calling any mcplinear-server* tool (here and in Step 10), verify it exists in the current session; MCP tool names change, so fall back to the Linear web UI if it is absent.

mcp__linear-server__save_issue:
  title: "ADR: {Decision Title}"
  team: "Hikmaai"
  project: "ADR Lifecycle"
  state: "In Progress"
  assignee: "me"
  priority: 2  (or as appropriate)
  description: "One-line summary.\n\nRepo: hikma-system-design\nBranch: adr/{NNN}-{kebab-title}"

Note the ticket identifier (e.g., HIK-249): the numeric part (249) is the ADR number.

Step 4: Create Branch

cd ~/Development/hikmaAI/hikma-system-design
git checkout -b adr/{NNN}-{kebab-title} main

Example: adr/249-mirsad-cryptographic-decision-trail

Step 5: Write the ADR

1. Copy adr/TEMPLATE.md to adr/ADR-{NNN}-{kebab-title}.md
2. Fill in all sections following the template guidance
3. Set frontmatter fields:

- Status: Drafting - Linear: HIK-{NNN} - Obsidian: [[{NNN}-{kebab-title}]]

Follow the HikmaAI ADR format exactly (full section-by-section template in references/adr-format.md).

Step 6: Update README.md

Add a row to the ADR Index table in hikma-system-design/README.md:

| {NNN} | {project} | {Title} | Drafting |

Also update the naming convention if it still references the old format.

Step 7: Store in Vault

Save using the obsidian skill:

obsidian create name="Projects/HikmaAI/HLD/ADR-{NNN}-{Title}" content="..." silent

Fallback (direct file access): Write to /Users/maroffo/Library/Mobile Documents/iCloud~md~obsidian/Documents/Projects/HikmaAI/HLD/ADR-{NNN}-{Title}.md

Step 8: Review

Run dx-reviewer agent on the ADR file, focusing on:

• Completeness (all sections present)
• Clarity (decisions unambiguous)
• Evidence (claims backed by data/code)
• Actionability (enough detail to implement)

This launch cannot pass isolation: "worktree": the ADR file is still uncommitted here (Step 9 commits it), and a reviewer worktree materialises at the default branch, where the file does not exist. Open the brief with the first line ISOLATION-EXEMPT: ADR review, the target file is uncommitted and the reviewer only reads it, which is what reviewer-isolation-guard reads; the reviewer then stays read-only agent-side, which is all this step wants.

Alternatively, if the ADR is short and straightforward, skip the agent and self-review against the checklist above.

Step 9: Commit, Push, PR

Commit:

git add adr/ADR-{NNN}-{kebab-title}.md README.md [any other changed files]
git commit -m "docs: ADR-{NNN} {Title} (HIK-{NNN})

{One-line summary of the decision.}

Co-Authored-By: Claude <model> <[email protected]>"

Replace <model> with the current model name (e.g. the model running this session); do not hardcode a specific version.

Push + PR:

git push -u origin adr/{NNN}-{kebab-title}

gh pr create \
  --title "ADR-{NNN}: {Title}" \
  --body "## Summary
- **ADR-{NNN}**: {Decision summary}

**Linear:** [HIK-{NNN}](https://linear.app/hikmaai/issue/HIK-{NNN})

## Test plan
- [ ] Review ADR content for technical accuracy
- [ ] Verify README index entry

Step 10: Update Linear Status

Move the ticket to "In Review" and attach the PR link:

mcp__linear-server__save_issue:
  id: "HIK-{NNN}"
  state: "In Review"
  links: [{"url": "{PR_URL}", "title": "PR: ADR-{NNN}"}]

After Merge (manual or automated)

• Move Linear ticket to Done: state: "Done"
• Update ADR status to Status: Accepted (follow-up commit or part of next PR)
• GitHub Action syncs to Notion automatically

ADR Status Lifecycle

Numbering

Naming Conventions

Style Rules

• No em dashes; use commas, colons, semicolons, or parentheses
• Tables for structured comparisons (always)
• Code blocks for API schemas, configs, deployment patterns
• Bold for core decisions and key terms
• --- horizontal rules between major parts
• ASCII diagrams for architecture flows (no Mermaid in ADRs)
