Releases 0.2.0, which adds support for Java!

* Add initial skill for testing, which is simply Steve's skill

* Rename skill to 'temporal-dev' and update version

Updated skill name and version for Temporal Python.
* Use claude to merge Steve's, Max's, and Mason's skills. Did a review pass using claude's skill devlopment skills

* Add missing things from Steve

* trigger tweaks

* Add in common gotchas from Johann

* Fix typos and reference links

* 2 more typo fixes
When a workflow is cancelled mid-saga, compensations must run in a
cancellation-protected scope, otherwise they are immediately cancelled
before they can execute.

- Python: wrap compensation loop in asyncio.shield() so it runs even
  when the workflow receives a CancelledError
- TypeScript: wrap compensation loop in CancellationScope.nonCancellable()
  so it runs even when the root scope is cancelled (per official docs:
  "Cleanup logic must be in a nonCancellable scope")
- TypeScript: also fix compensation registration order — register BEFORE
  calling the activity (was already correct in Python)

* progress on go

* Go translation workflow completed.

* missed a few spots

* Manual edits

* Address feedback

* Add gotcha about anonymous local activities

* Sample code for payload converter

- Fix wrong reference path in go.md (python -> go determinism-protection)
- Add missing .md extension to testing reference in go/determinism-protection.md
- Fix typos: "Activty" -> "Activity", "accomplised" -> "accomplished", "discourged" -> "discouraged"
* docs: add @workflow.init decorator to python.md Key Concepts

* Add Java SDK reference files (11 files)

Create complete Java reference documentation covering:
- java.md: Entry point with quick start tutorial, key concepts
- patterns.md: 17 patterns (signals, queries, updates, child workflows,
  saga, cancellation scopes, heartbeating, etc.)
- determinism.md: Safe alternatives table, forbidden operations
- determinism-protection.md: Convention-based enforcement (no sandbox)
- error-handling.md: ApplicationFailure, retry/timeout config
- gotchas.md: Non-deterministic operations, cancellation, heartbeating
- testing.md: TestWorkflowEnvironment, Mockito mocking, replay testing
- versioning.md: Workflow.getVersion(), worker versioning
- data-handling.md: Jackson, PayloadConverter, encryption, search attributes
- observability.md: SLF4J logging, Micrometer metrics
- advanced-features.md: Schedules, async completion, worker tuning

* Fix Java alignment issues from self-review

- Reduce gotchas.md Non-Deterministic Operations from ~94 lines to ~12
  (reference determinism.md instead of duplicating)
- Remove Workflow Failure Exception Types duplication from error-handling.md
  (keep only in advanced-features.md)
- Expand versioning.md Worker Versioning with Key Concepts, PINNED vs
  AUTO_UPGRADE, Deployment Strategies subsections
- Fix section names to match Python reference style:
  Activity Heartbeat Details, Handling Activity Errors,
  Retry Policy Configuration, Workflow Test Environment,
  Mocking Activities, Workflow Replay Testing
- Reduce data-handling.md Payload Encryption verbosity
- Reduce observability.md Logger Customization verbosity
- Reduce testing.md to single approach per section
- Rename determinism.md "Convention-Based Enforcement" to "SDK Protection"
- Fix handler guidance in patterns.md to match Python

* Fix correctness issues in Java reference files

- patterns.md: Fix Queries section — ActivityStub → typed interface
  (Workflow.newActivityStub returns the typed interface, not ActivityStub)
- data-handling.md: Add missing ProtobufPayloadConverter to default
  converter chain (4th of 5 converters)

* Add Java to SKILL.md and core/determinism.md

- SKILL.md: Add "Temporal Java" trigger phrase, update Overview to
  list Java, add Java entry to Getting Started references
- core/determinism.md: Add Java entry to SDK Protection Mechanisms
  (no sandbox, convention-based, NonDeterministicException at replay)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Apply manual editorial fixes to Java references

- java.md: Remove "Understanding Replay" section (covered by Overview),
  simplify File Organization note (no sandbox rationale)
- gotchas.md: Move Heartbeating before Cancellation, make Wrong Retry
  Classification brief with reference (not inline examples)
- error-handling.md: Remove editorializing from Workflow Failure note
- determinism-protection.md: Remove cross-language comparison paragraph
  (state Java's approach on its own terms)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Add temporal-workflowcheck static analysis to Java determinism docs

- determinism-protection.md: Add "Static Analysis with temporal-workflowcheck"
  section with Gradle/Maven setup, manual run, and suppression instructions.
  Beta warning included.
- determinism.md: Update overview and SDK Protection to reference workflowcheck
- core/determinism.md: Update Java entry in SDK Protection Mechanisms

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Integrate feedback from Go PR into Java patterns

- Updates: Add validator note — validators must not mutate state or
  block (matches note added to Python, TypeScript, Go, and core)
- Saga Pattern: Use Workflow.newDetachedCancellationScope() for
  compensations so they execute even if the workflow is cancelled
  (mirrors Go's workflow.NewDisconnectedContext pattern)

* docs: add @WorkflowInit description to java.md Key Concepts

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* Apply suggestions from code review

Co-authored-by: Brian Strauch <brian@brianstrauch.com>

* strongly recommend java 21+

* Softened stance on static checker and replay testing.

* address python/typescript sandboxing comment
