oak-add-config Skill

You are an expert in the Apache Jackrabbit Oak oak-store-document module. When this skill is invoked, you will add a new OSGi configuration property.

Supporting files

• Detailed production code patterns (steps 2–6): osgi-config-patterns.md
• Detailed test patterns (steps 7–10): test-patterns.md
• Wiring into usage class + compile/test (steps 11–12): wiring-and-verification.md

REQUIRED INPUT

The user must provide these values when invoking the skill. If any are missing, stop and ask:

Parameter	Description	Example
configName	camelCase OSGi attribute method name	avoidExclusiveMergeLock
type	Java type: boolean, int, long, String	boolean

defaultValue is optional — if not provided, use the Java default for the given type:

• boolean → false
• int / long → 0
• String → ""

The following are optional — derive or infer them if not provided:

Parameter	Description	How to derive if missing
jiraId	JIRA ticket ID	Deduce from current branch name (see below)
attrName	Human-readable OSGi display name	Convert configName from camelCase to Title Case
description	Full OSGi description text	Ask the user for a brief description, then expand it
scope	both, mongo-only, or rdb-only	Ask the user explicitly. Default is mongo-only.
featureToggle	Whether to add a feature toggle (true / false)	Ask the user explicitly. Default is false.

Deducing jiraId from the branch: Run git branch --show-current and extract the JIRA ID (e.g. OAK-12139 → jiraId=OAK-12139; issue/OAK-12139 → jiraId=OAK-12139). If it differs from a user-supplied value, warn. If none can be deduced, ask.

Before proceeding, ask both optional questions in a single prompt:

1. "Which backends does this config apply to? (mongo-only / rdb-only / both, default: mongo-only)"
2. "Do you want a feature toggle for this config? (yes/no, default: no)"

---

DERIVED IDENTIFIERS

From the inputs, derive:

• DEFAULT_CONST → DEFAULT_ + UPPER_SNAKE_CASE of configName e.g. avoidExclusiveMergeLock → DEFAULT_AVOID_EXCLUSIVE_MERGE_LOCK
• setterName → set + PascalCase(configName)
• getterName → same as configName
• utilsMethod → is + PascalCase(configName stripped of avoid/enable/use) + Enabled e.g. isAvoidMergeLockEnabled

featureToggle=true only:

• FT_NAME_CONST → FT_NAME_ + UPPER_SNAKE_CASE of configName
• FT_VALUE → "FT_" + UPPER_SNAKE + "_" + jiraId
• featureField → docStore + PascalCase(configName stripped of trailing Enabled) + Feature

EXECUTION STEPS

Work through every step in order. Do NOT skip any step.

Read the supporting files as you reach each group of steps.

1. Read key files — locate insertion points in all 9 files (listed below)
2. Configuration.java — add @AttributeDefinition + import → see osgi-config-patterns.md
3. DocumentNodeStoreService.java — DEFAULT constant, FT_NAME, Feature field, activate/deactivate, configureBuilder → see osgi-config-patterns.md
4. DocumentNodeStoreBuilder.java — value field, getter/setter, Feature getter/setter → see osgi-config-patterns.md
5. RDBDocumentNodeStoreBuilder.java — override to disable (scope=mongo-only) → see osgi-config-patterns.md
6. Utils.java — add isXxxEnabled() method → see osgi-config-patterns.md
7. DocumentNodeStoreServiceConfigurationTest.java → see test-patterns.md
8. MongoDocumentNodeStoreBuilderTest.java → see test-patterns.md
9. RDBDocumentNodeStoreBuilderTest.java → see test-patterns.md
10. UtilsTest.java → see test-patterns.md
11. Wire into usage class → see wiring-and-verification.md
12. Compile and run tests → see wiring-and-verification.md

QUALITY CHECKLIST

Before finishing, verify:

• Configuration.java has a new @AttributeDefinition entry with correct default import
• DocumentNodeStoreService.java has DEFAULT constant and configureBuilder value setter
• (featureToggle=true) DocumentNodeStoreService.java has FT_NAME constant, Feature field, activate registration, deactivate cleanup, and feature setter in configureBuilder
• DocumentNodeStoreBuilder.java has value field + getter/setter pair
• (featureToggle=true) DocumentNodeStoreBuilder.java has Feature field + Feature getter/setter pair
• RDBDocumentNodeStoreBuilder.java overrides value getter/setter to disable (scope=mongo-only)
• (featureToggle=true) RDBDocumentNodeStoreBuilder.java also overrides Feature getter/setter (scope=mongo-only)
• Utils.java has isXxxEnabled() with proper javadoc
• DocumentNodeStoreServiceConfigurationTest.java tests default value + override
• MongoDocumentNodeStoreBuilderTest.java tests default getter (+ null feature if featureToggle=true)
• RDBDocumentNodeStoreBuilderTest.java has symmetrical default-value tests (scope=both) or override-disabled tests (scope=mongo-only)
• UtilsTest.java has correct number of tests for featureToggle + scope combination
• DocumentNodeStore.java reads the config via {utilsMethod}(builder) and stores it as a field
• Target class receives and uses the field correctly
• All tests pass
• No new static imports added to any test file

---

IMPORTANT CONSTRAINTS

• Assertion style: match the existing imports in each file — do NOT add new imports. If the file uses assertFalse(...) (static), use that; if it uses Assert.assertFalse(...), use that.
• No static imports in new production code
• JUnit 4 only (@Test from org.junit.Test)
• Apply standards only to new code — never reformat or rename existing code
• Follow the exact naming and placement patterns shown in the supporting files
