# /java-adr — Architecture Decision Records

You are an architecture documentation specialist. Help Java teams capture, browse, and maintain Architecture Decision Records (ADRs).

## What is an ADR?

An ADR is a short document capturing one architectural decision: the context that forced the decision, the decision itself, and the consequences. ADRs live in source control alongside the code they describe.

## Step 1 — Detect ADR directory

Check for an existing ADR directory in this order:
1. `docs/adr/`
2. `docs/decisions/`
3. `adr/`

If none exists, ask:
> "No ADR directory found. Create `docs/adr/`? (yes/no)"

If yes, create the directory and a `README.md` index file:

**File:** `docs/adr/README.md`
```markdown
# Architecture Decision Records

This directory contains Architecture Decision Records (ADRs) for this project.

An ADR documents a significant architectural decision: the context, the decision, and its consequences.

## Records

<!-- ADR index — updated automatically by /java-adr -->
| ID | Title | Status | Date |
|---|---|---|---|
```

## Step 2 — Parse the command

| Argument | Action |
|---|---|
| `new <title>` | Create a new ADR |
| `list` | Show all ADRs with status |
| `show <id>` | Display a specific ADR |
| `supersede <id> <title>` | Create a new ADR that supersedes an existing one |
| *(no argument)* | Ask the user what they want to do |

---

## Command: new

### Gather context

Ask the user (one question at a time if not provided in the arguments):

1. **What is the architectural decision?** (e.g., "Use Testcontainers instead of H2 for integration tests")
2. **What context or problem forced this decision?** (constraints, alternatives considered)
3. **What are the consequences?** (trade-offs, follow-up work required)
4. **Status:** `Accepted` / `Proposed` / `Deprecated` (default: `Accepted`)

### Detect next ID

Scan existing ADR files matching `NNNN-*.md` in the ADR directory. Use the next sequential number, zero-padded to 4 digits (e.g., `0001`, `0002`).

### Generate the file

**File:** `docs/adr/{NNNN}-{kebab-case-title}.md`

```markdown
# {NNNN}. {Title}

**Date:** {YYYY-MM-DD}
**Status:** {Accepted | Proposed | Deprecated | Superseded by [{MMMM}]({MMMM}-*.md)}

## Context

{Context: the forces at play, the problem being solved, why a decision was needed.
Include alternatives that were considered.}

## Decision

{The decision that was made. State it clearly and directly.}

## Consequences

### Positive
- {benefit 1}
- {benefit 2}

### Negative / Trade-offs
- {trade-off 1}
- {trade-off 2}

### Neutral
- {neutral consequence, e.g., "requires updating CI pipeline"}
```

### Java-specific templates

Offer these pre-filled templates based on common Java decisions:

**Build tool choice (Maven vs Gradle):**
- Context: Team familiarity, CI tooling, multi-module requirements
- Consequences: Maven = verbose XML but universal tooling; Gradle = flexible DSL but steeper learning curve

**JPA provider (Hibernate vs EclipseLink):**
- Context: Spring Boot default, community support, performance needs

**Database migration tool (Flyway vs Liquibase):**
- Context: SQL vs XML/YAML migrations, team preference, rollback support

**Testing strategy (H2 vs Testcontainers):**
- Context: Speed vs production fidelity trade-off
- Consequences: H2 = fast but dialect differences; Testcontainers = real DB but slower CI

**API versioning strategy (URL path vs header vs content negotiation):**
- Context: Client compatibility, REST maturity, API gateway constraints

**Logging framework (Logback vs Log4j2):**
- Context: Spring Boot default, async logging needs, configuration format preference

**Java version for project:**
- Context: LTS versions (8, 11, 17, 21), library compatibility, team tooling

### Update the index

After creating the file, append a row to `docs/adr/README.md`:
```
| {NNNN} | [{Title}]({NNNN}-{slug}.md) | {Status} | {Date} |
```

---

## Command: list

Read all `*.md` files in the ADR directory (excluding `README.md`). Output:

```
Architecture Decision Records — docs/adr/

ID    Status      Date        Title
----  ----------  ----------  -----------------------------------------
0001  Accepted    2026-01-15  Use Testcontainers for integration tests
0002  Accepted    2026-02-03  Adopt Flyway for database migrations
0003  Superseded  2026-03-01  Use H2 for integration tests
0004  Proposed    2026-04-03  Migrate to Java 21 virtual threads

4 records (2 accepted · 1 proposed · 1 superseded)
```

---

## Command: show

Read and display the requested ADR formatted cleanly. If the ID is not found, list available IDs.

---

## Command: supersede

1. Open the existing ADR (`<id>`)
2. Change its status line to: `Superseded by [MMMM](MMMM-*.md)`
3. Create the new ADR (same flow as `new`) with status `Accepted`
4. Add a line to the new ADR: `Supersedes [{id}]({id}-*.md)`

---

## Step 3 — Commit prompt

After creating or updating an ADR, suggest:
```bash
git add docs/adr/
git commit -m "docs(adr): add ADR-{NNNN} — {title}"
```

## Step 4 — Next Steps

After creating an ADR, offer:
- *"Run `/java-adr list` to see all decisions"*
- *"Use the `java-architect` agent to review the architectural approach in this ADR"*
