+# Technical Design: OpenCode SDK v1.3.14 Alignment
+
+## Context
+
+The plugin currently uses OpenCode SDK v1.2.25 (stable), but the Docker test environment pulls the latest OpenCode version without version pinning. This creates a version mismatch that prevents proper verification of SDK upgrades.
+
+### Current State
+- SDK version: v1.2.25 (confirmed stable, tested)
+- Docker OpenCode: unpinned (pulls latest, currently v1.3.14+)- Known broken versions: v1.3.8 - v1.3.13 (NAPI loading issues, Issue #20623)
+- Target version: v1.3.14 (crosses AI SDK v5→v6 migration, Tool.define() bugfix)
+
+### Stakeholders
+- Development team: needs reliable test environment for SDK upgrades
+- Release workflow: requires version alignment for `verify:full` execution
+- Users: benefit from validated OpenCode version compatibility
+
+## Goals/ Non-Goals
+
+**Goals:**
+- Align OpenCode version in Docker test environment with SDK version
+- Validate v1.3.14 compatibility across all plugin hooks
+- Document verification results for future reference
+- Unblock BL-060 (OpenCode v1.3.14 compatibility confirmation)
+
+**Non-Goals:**
+- v1.4.0+ compatibility evaluation (BL-056, separate effort)
+- Multi-version test matrix (BL-057, future work)
+- Runtime version detection (BL-058, future work)
+
+## Decisions
+
+### Decision 1: Version Pinning Strategy
+
+**Choice**: Pin OpenCode to exact version v1.3.14 in Dockerfile
+
+**Rationale**:
+- Ensures reproducible test environment
+- Prevents accidental use of broken versions (v1.3.8-v1.3.13)
+- Aligns with SDK version for proper verification
+- Allows systematic upgrade path validation
+
+**Alternatives considered**:
+- Use latest version: Rejected - too volatile, may pull broken versions
+- Use version range: Rejected - v1.3.8-v1.3.13 are known broken
+- Multiple Dockerfiles for different versions: Rejected - out of scope for BL-059
+
+### Decision 2: SDK Upgrade Approach
+
+**Choice**: Upgrade both `@opencode-ai/plugin` and `@opencode-ai/sdk` to v1.3.14 simultaneously
+
+**Rationale**:
+- SDK and plugin versions must match for proper functionality
+- Single atomic change for easier rollback if needed
+- Simplifies verification scope
+
+**Alternatives considered**:- Staged upgrade (one at a time): Rejected - creates incompatibility
+- Keep v1.2.25: Rejected - doesn't meet BL-059 requirement
+
+### Decision 3: VerificationScope
+
+**Choice**: Run full `verify:full` suite plus focused hook validation
+
+**Rationale**:
+- `test:foundation`: Validates session.idle hook (critical for auto-capture)
+- `test:regression`: Validates all 17 tool execute behaviors
+- `test:e2e`: Validates complete write → restart → search flow
+- Comprehensive coverage ensures nothing breaks
+
+**Alternatives considered**:
+- Minimal tests only (e2e): Rejected - insufficient for SDK upgrade validation
+- Skip e2e: Rejected - critical for end-to-end workflow validation
+
+### Decision 4: Documentation Update
+
+**Choice**: Update `docs/OPENCODE_COMPATIBILITY.md` with v1.3.14 status
+
+**Rationale**:
+- Centralized compatibility documentation
+- Users can reference verified version status
+- Supports future SDK upgrade decisions
+
+**Alternatives considered**:
+- Separate changelog entry only: Rejected - compatibility matrix is more discoverable
+- No documentation: Rejected - loses institutional knowledge
+
+## Risks/ Trade-offs
+
+### Risk 1: AI SDK v6 Migration Impacts
+**Risk**: v1.3.4 introduced AI SDK v5 → v6 migration which may affect `session.idle` hook triggering
+**Mitigation**: Run `test:foundation` specifically to validate session.idle behavior after upgrade
+**Rollback**: If session.idle fails, document findings and assess v1.4.x alternative
+
+### Risk 2: Tool.define() Behavior Change
+**Risk**: v1.3.14 fixed Tool.define() bug where `execute` was wrapped multiple times
+**Mitigation**: Run `test:regression` to verify all 17 tools execute correctly
+**Rollback**: If tools fail, investigate execute path and document behavior differences
+
+### Risk 3: Docker Build Consistency
+**Risk**: Docker image builds may fail or produce inconsistent results across environments
+**Mitigation**: Use `--no-cache` for initial build, document exact build process
+**Rollback**: Keep v1.2.25 Dockerfile version in git history for quick reversion
+
+### Risk 4: Plugin Installation Mechanism
+**Risk**: v1.3.11 changed plugin installation mechanics (version pinning, script blocking)
+**Mitigation**: Verify `prepublishOnly` script runs correctly in v1.3.14 context
+**Rollback**: If installation fails, document blocking mechanism and assess workarounds
+
+## Migration Plan
+
+### Step 1: Version Alignment (Development)
+1. Update `Dockerfile.opencode` line 13 to pin v1.3.14
+2. Update `package.json` dependencies to v1.3.14
+3. Run `npm install` to update lockfile
+4. Commit changes to feature branch
+
+### Step 2: Local Verification (Development)
+```bash
+# Build Docker image with new version
+docker compose build --no-cache
+
+# Start container
+docker compose up -d
+
+# Run verification inside container
+docker compose exec opencode-dev npm run verify:full
+```
+
+### Step 3: Focused Hook Validation (Development)
+```bash
+# Specific hook tests
+npm run test:foundation  # session.idle validation
+npm run test:regression  # 17 tools validation
+npm run test:e2e         # end-to-end flow
+```
+
+### Step 4: Documentation (Development)
+1. Update `docs/OPENCODE_COMPATIBILITY.md` with v1.3.14 verified status
+2. Document any behavior changes or workarounds required
+3. Update roadmap.md to mark BL-059 as done
+
+### Step 5: Rollback Strategy (If Needed)
+```bash
+# Revert Dockerfile.opencode
+git checkout HEAD~1 -- Dockerfile.opencode
+
+# Revert package.json
+git checkout HEAD~1 -- package.json package-lock.json
+
+# Rebuild and retest
+docker compose build --no-cache
+docker compose exec opencode-dev npm run verify:full
+```
+
+## Open Questions
+
+1. **Q**: Should we create a separate Dockerfile for v1.4.x testing?
+   **A**: Out of scope for BL-059. BL-056/BL-060 will handle v1.4.0+ evaluation.
+
+2. **Q**: Do we need version-specific test configurations?
+   **A**: BL-057 (SDK upgrade test matrix) will address multi-version testing.
+
+3. **Q**: What if `session.idle` doesn't trigger in v1.3.14?
+   **A**: Document the behavior difference, assess v1.4.x alternative, or file upstream issue.

+# Align OpenCode SDK Version to 1.3.14 for Testing
+
+## Why
+
+The plugin currently uses OpenCode SDK v1.2.25, but the Docker test environment pulls the latest OpenCode version (currently v1.3.14+). Versions v1.3.8-v1.3.13 have critical NAPI loading issues. This creates a version mismatch between developmen tenvironment (SDK v1.2.25) and test environment (OpenCode v1.3.14), preventing proper verification of the SDK upgrade path.
+
+To validate SDK v1.3.14 compatibility, we need to align both the Docker OpenCode version and SDK version to v1.3.14, enabling the team to run `verify:full` and confirm all hooks (particularly `session.idle` and tool execute behaviors) function correctly after the upgrade.
+
+## What Changes
+
+- Pin OpenCode version to v1.3.14 in `Dockerfile.opencode` (currently unpinned/ latest)
+- Update `@opencode-ai/plugin` and `@opencode-ai/sdk` from v1.2.25 to v1.3.14 in `package.json`
+- Run comprehensive verification suite (`npm run verify:full`) to validate upgrade
+- Document v1.3.14 compatibility status in `docs/OPENCODE_COMPATIBILITY.md`
+
+## Capabilities
+
+### New Capabilities
+
+- `opencode-v1314-verification`: Capability to verify plugin compatibility with OpenCode v1.3.14, including session.idle hook triggering, tool execute behavior, and full E2E flow testing.
+
+### Modified Capabilities
+
+- `dependency-upgrade-workflow`: Updated workflow to include OpenCode v1.3.14 specific verification steps for AI SDK v5→v6 migration impacts.
+
+## Impact
+
+### Code Changes
+- `Dockerfile.opencode`: Uncomment and update version pinning to v1.3.14
+- `package.json`: Update SDK dependencies from v1.2.25 to v1.3.14
+- `docs/OPENCODE_COMPATIBILITY.md`: Update compatibility matrix with v1.3.14 status
+
+### Testing Impact
+- Docker test environment will use OpenCode v1.3.14 (aligned withSDK version)
+- `test:foundation`: Validates session.idle hook and event system compatibility
+- `test:regression`: Validates 17 tool execute behaviors after Tool.define() bug fix
+- `test:e2e`: Validates full write → restart → search flow
+
+### Dependencies
+- `@opencode-ai/plugin`: v1.2.25 → v1.3.14
+- `@opencode-ai/sdk`: v1.2.25 → v1.3.14

+### Risk Assessment
+- **High Risk**: AI SDK v5 → v6 migration (v1.3.4) may affect session.idle hook triggering
+- **Medium Risk**: Tool.define() bug fix (v1.3.14) may change execute behavior for all 17 tools
+- **Medium Risk**: Plugin installation mechanism changes (v1.3.11) may affect prepublishOnly flow

+# dependency-upgrade-workflow Specification (Modified for OpenCode SDK)
+
+## MODIFIED Requirements
+
+### Requirement: Weekly OpenCode SDK version check
+
+The project MUST provide a scheduled GitHub Actions workflow that checks for available OpenCode SDK version updates on a weekly basis.
+
+#### Scenario: Weekly check runs on schedule
+- **WHEN** the scheduled weekly check runs
+- **THEN** the workflow compares current OpenCode SDK version in package.json against the latest published version on npm
+
+#### Scenario: OpenCode SDK version delta detected
+- **WHEN** a newer OpenCode SDK version is available
+- **THEN** the workflow reports the version delta and initiates compatibility verification
+
+### Requirement: OpenCode SDK compatibility verification
+
+The project MUST verify OpenCode SDK compatibility before recommending an upgrade by running the full test suite against the candidate version in an isolated Docker environment.
+
+#### Scenario: Docker environment uses candidate SDK version
+- **WHEN** an OpenCode SDK update is available
+- **THEN** the workflow builds a Docker image with the candidate OpenCode version pinned in Dockerfile.opencode
+
+#### Scenario: Compatibility verification includes hook validation
+- **WHEN** OpenCode SDK compatibility verification runs
+- **THEN** the workflow executes test:foundation to validate session.idle and event hooks
+- **AND** the workflow executes test:regression to validate all 17 tool execute behaviors
+- **AND** the workflow executes test:e2e to validate end-to-end memory lifecycle
+
+#### Scenario: Compatibility test passes with v1.3.14 specifics
+- **WHEN** verification tests pass with v1.3.14
+- **THEN** the workflow confirms:
+  - session.idle hook triggers correctly after AI SDKv6 migration
+  - Tool.execute behavior is correct after Tool.define() bug fix
+  - End-to-end memory flow works without regression
+
+#### Scenario: Compatibility test fails
+- **WHEN** any verification test fails with the candidate OpenCode version
+- **THEN** the workflow reports the failure with detailed error logs
+- **AND** does NOT create an upgrade issue
+
+### Requirement: Automated issue creation for OpenCode SDK upgrades
+
+The project MUST create a GitHub issue when an OpenCode SDK update passes compatibility testing.
+
+#### Scenario: Issue created for compatible OpenCode SDK update
+- **WHEN** an OpenCode SDK update is available and passes compatibility testing
+- **THEN** the workflow creates a GitHub issue with:
+  - Current and target SDK versions
+  - Breaking changes or migration notes (e.g., AI SDK v5→v6)
+  - Verification evidence (test results)
+  - Actionable upgrade checklist
+
+#### Scenario: Duplicate OpenCode SDK issue prevention
+- **WHEN** an OpenCode SDK upgrade issue already exists and is open
+- **THEN** the workflow does NOT create a duplicate issue
+
+### Requirement: Breaking changes documentation for OpenCode SDK
+
+The project MUST document OpenCode SDK breaking changes that affect plugin functionality.
+
+#### Scenario: Breaking changes are identified and documented
+- **WHEN** an OpenCode SDK version contains breaking changes
+- **THEN** the workflow identifies affected plugin components (hooks, tools, APIs)
+- **AND** documents migration steps or workarounds in OPENCODE_COMPATIBILITY.md
+
+#### Scenario: AI SDK migration risks are assessed
+- **WHEN** OpenCode SDK upgrade involves AI SDK major version change (e.g., v5→v6)
+- **THEN** the workflow specifically validates affected hooks:
+  - session.start/end/idle/compacted
+  - experimental.text.complete
+  - experimental.chat.system.transform
+  - All tool hooks
+
+#### Scenario: Tool.define() bug fix impact is documented
+- **WHEN** OpenCode SDK v1.3.14+ is evaluated
+- **THEN** the documentation notes Tool.define() execute wrapping behavior change
+- **AND** verifies all 17 custom tools execute correctly

+# opencode-v1314-verification Specification
+
+## ADDED Requirements
+
+### Requirement: OpenCode version is pinned in Docker environment
+
+The project SHALL pin OpenCode version to v1.3.14 in the Docker test environment to ensure reproducible testing and alignment with SDK version.
+
+#### Scenario: Dockerfile specifies OpenCode v1.3.14
+- **WHEN** Dockerfile.opencode is built
+- **THEN** the resulting Docker image contains OpenCode v1.3.14 exactly
+
+#### Scenario: Docker build produces consistent image
+- **WHEN** `docker compose build --no-cache` is executed
+- **THEN** the build deterministically installs OpenCode v1.3.14 without relying on latest
+
+### Requirement: SDK dependencies match OpenCode version
+
+The project SHALL update both `@opencode-ai/plugin` and `@opencode-ai/sdk` dependencies to v1.3.14 to align with the Docker OpenCode version.
+
+#### Scenario: package.json declares SDK v1.3.14
+- **WHEN** package.json is inspected
+- **THEN** both `@opencode-ai/plugin` and `@opencode-ai/sdk` specify version 1.3.14
+
+#### Scenario: npm install resolves to v1.3.14
+- **WHEN** `npm install` is executed
+- **THEN** node_modules contains OpenCode SDK v1.3.14 artifacts
+
+### Requirement: Full verification suite passes with v1.3.14
+
+The project SHALL execute `npm run verify:full` successfully with OpenCode v1.3.14 to confirm compatibility.
+
+#### Scenario: verify:full completes without errors
+- **WHEN** `npm run verify:full` is executed in Docker v1.3.14 environment
+- **THEN** all tests pass with exit code 0
+
+#### Scenario: verify:full validates all test categories
+- **WHEN** `npm run verify:full` is executed
+- **THEN** test:foundation, test:regression, test:retrieval, and benchmark:latency all pass
+
+### Requirement: session.idle hook triggers correctly in v1.3.14
+
+The project SHALL validate that the `session.idle` hook triggers after AI SDK v5→v6 migration to ensure auto-capture functionality remains intact.
+
+#### Scenario: session.idle hook triggers after session becomes idle
+- **WHEN** an OpenCode session transitions to idle state in v1.3.14
+- **THEN** the hook triggers and memory auto-capture executes
+
+#### Scenario: Auto-capture writes memory to store
+- **WHEN** session.idle hook triggers in v1.3.14
+- **THEN** captured memory is persisted to LanceDB store
+
+### Requirement: All17 tools execute correctly after Tool.define() fix
+
+The project SHALL validate that all 17 custom tools execute correctly after v1.3.14 Tool.define() bug fix.
+
+#### Scenario: test:regression validates tool execution
+- **WHEN** `npm run test:regression` is executed with v1.3.14
+- **THEN** all 17 tools pass their execution tests
+
+#### Scenario: Tool execute wrapper no longer duplicates
+- **WHEN** a tool is invoked in v1.3.14
+- **THEN** the execute function is wrapped exactly once (not multiple times)
+
+### Requirement: End-to-end write-restart-search flow works in v1.3.14
+
+The project SHALL validate the complete memory lifecycle (write → restart → search) works correctly in v1.3.14.
+
+#### Scenario: test:e2e validates complete flow
+- **WHEN** `npm run test:e2e` is executed with v1.3.14
+- **THEN** the test passes, confirming write, restart, and search operations work end-to-end
+
+#### Scenario: Memory persists across restart
+- **WHEN** memory is written in v1.3.14 environment
+- **AND** OpenCode server is restarted
+- **THEN** the memory is searchable via memory_search tool
+
+### Requirement: Compatibility status is documented
+
+The project SHALL update `docs/OPENCODE_COMPATIBILITY.md` with v1.3.14 verification results and behavior notes.
+
+#### Scenario: Compatibility matrix includes v1.3.14 entry
+- **WHEN** OPENCODE_COMPATIBILITY.md is inspected
+- **THEN** v1.3.14 is listed with status "✅ Verified" or "⚠️ Known Issues" with details
+
+#### Scenario: Behavior changes are documented
+- **WHEN** v1.3.14 introduces behavior differences from v1.2.25
+- **THEN** those differences are documented in OPENCODE_COMPATIBILITY.md
