Release v2.1.2

[2.1.2] - 2025-12-12

🩹 Bug Fixes

• 🩹 fix(ci): add missing LANGSMITH_ORGANIZATION_ID to release workflow (#707)

Add LANGSMITH_ORGANIZATION_ID environment variable to the pre-release-validation job
in the release workflow to match the CI workflow configuration.

According to docs/dev/environment-variables.md and issue #660, all three environment
variables (LANGSMITH_API_KEY, LANGSMITH_ORGANIZATION_ID, LANGSMITH_WORKSPACE_ID) are
required for integration tests. The CI workflow already has all three, but the release
workflow was missing LANGSMITH_ORGANIZATION_ID, causing test failures.

Fixes #706

🩹 Bug Fixes

• 🩹 fix(sdk): make AnnotationQueue timestamps optional (#655)

Fixes #624

Problem

The langstar queue list command was failing with "error decoding response body"
when attempting to deserialize annotation queues from the LangSmith API.

Root Cause

The AnnotationQueue struct defined created_at and updated_at as required
fields, but according to the OpenAPI spec (annotation-queue-schemas.json:436-442),
these fields are NOT in the required fields list. The API was returning queues
without these timestamp fields, causing deserialization failures.

Solution

1. Changed created_at and updated_at from DateTime<Utc> to Option<DateTime<Utc>>
2. Updated all CLI display code to handle optional timestamps gracefully
3. Added test case to verify deserialization works without timestamps

Changes

SDK (sdk/src/annotation_queues.rs):

• Made AnnotationQueue.created_at and updated_at optional fields
• Updated deserializer to use deserialize_flexible_datetime_opt
• Added test case for queues without timestamps

CLI (cli/src/commands/queue.rs):

• Updated QueueRow::from() to handle optional created_at
• Updated execute_create() to conditionally print created_at
• Updated execute_get() to conditionally print both timestamps

Test Plan

• All annotation_queues unit tests pass (11/11)
• cargo check --workspace --all-features passes
• cargo clippy --workspace --all-features passes
• cargo fmt passes
• New test verifies deserialization without timestamps works

• 🩹 fix(cli): add full_name display and UUID lookup support for prompts (#658)

• 🩹 fix(cli): add full_name display and UUID lookup support for prompts

Issue #625 reported two UX problems with prompt commands:

1. List displays incomplete handles that fail when used with get
2. Get doesn't accept UUID as input

Changes:

SDK (sdk/src/prompts.rs):

• Add full_name and owner fields to Prompt struct
• Add get_by_id() method for UUID-based prompt lookup
• Both fields are optional to maintain backwards compatibility

CLI (cli/src/commands/prompt.rs):

• Update list display to show full_name (owner/repo format)
• Fall back to constructing from owner + repo_handle if needed
• Update get command to detect and handle UUID input
• Add UUID detection logic (8-4-4-4-12 hex digit format)
• Display ID field in prompt details output
• Update help text to document handle and UUID support

Testing:

• Manually verified list shows full handles (e.g., "hardkothari/prompt-maker")
• Manually verified get works with full handles from list output
• Manually verified get works with UUID input
• JSON output includes new full_name and owner fields

• 🩹 fix(sdk): use pagination in get_by_id to search all prompts

The hardcoded limit of 100 could cause 404 errors for prompts that
exist but aren't in the first 100 results. Now uses pagination to
search through all prompts until the matching ID is found.

Addresses review feedback from Copilot on PR #658

• 🩹 fix(cli): improve UUID detection and fix documentation

• Use uuid::Uuid::parse_str() for robust UUID validation instead of manual
  pattern checking (more reliable, handles edge cases correctly)
• Fix owner field documentation to reflect actual API behavior
  (None for private prompts, not "-")

Addresses Copilot review feedback on PR #658

• 🧪 test: add coverage for UUID lookup functionality

Addresses Copilot review feedback on PR #658:

• Add SDK integration test for get_by_id() with pagination
• Add CLI tests for UUID detection and routing:
  1. Valid UUIDs correctly routed to get_by_id()
  2. Handles correctly identified (not treated as UUIDs)
  3. Invalid UUID formats handled gracefully

Tests verify issue #625 functionality:

• UUID detection using uuid::Uuid::parse_str()
• Routing to get_by_id() for UUIDs vs get() for handles
• End-to-end CLI behavior with UUID input

🔧 Build System

• 🔧 build(ci): ensure CI runs on prepare-release PRs (#641)

• 🔧 build(ci): ensure CI runs on prepare-release PRs

Fixes #640

Modifies CI workflow to always run on release branches (release/v*)
created by the prepare-release workflow, even when only docs/changelog
files are modified.

Changes

• Removed workflow-level paths-ignore filters (lines 8-12, 16-22)
• Added new changes job that determines whether to run CI based on:
  • Branch name pattern (always run for release/* branches)
  • Changed files (skip for docs-only on regular PRs)
• Made all CI jobs conditional on changes job output
• Updated all-jobs aggregator to include changes dependency

Implementation Details

The changes job checks:

1. If branch matches release/* pattern → always run CI
2. If branch is regular PR → check changed files
   • Skip if only: *.md, docs/**, *.txt, .gitignore
   • Run if any code files changed
3. If push to main → always run CI

This ensures the Release workflow's verify-ci job can find required
checks (Check, Test, Clippy, Build) even for release PRs that only
modify CHANGELOG.md and Cargo.toml.

• Create ColumnMetadata trait for column selection and TSV rendering
• Add print_text() method to OutputFormatter
• Update OutputFormat::from_str() to parse "text" format

between print_text() and print_table_with_options(). Both methods

• 📚 docs(pr-workflow): emphasize using /gh-pr-comment-reply for review comments

Clarifies that agents MUST use the dedicated /gh-pr-comment-reply slash command
when responding to review comments, rather than gh pr comment (creates top-level
comments) or manual gh api calls (error-prone).

Changes:

• Added CRITICAL section explaining how to reply in-thread using the slash command
• Updated Option 2 (Defer) example to show slash command usage
• Replaced Command Reference section to recommend slash command over manual methods
• Added explicit warnings against gh pr comment and manual gh api calls

This prevents the mistake of creating top-level PR comments that can't be marked
as resolved, which breaks the maintainer workflow.

• 🧪 test: add integration test for text format fallback

Adds test_model_config_list_text_format() to verify that --format text
correctly falls back to JSON output in Phase 1 (infrastructure only).

This test documents the current Phase 1 behavior and will be updated
in Phase 2 when Text format produces actual tab-separated values.

• 🩹 fix: add leaf node traversal to prep-next.py issue selection (#612)

• 🩹 fix: add leaf node traversal to prep-next.py issue selection

Fixes #611

Problem

The find_next_issue() method in prep-next.py would select parent issues
instead of traversing down to their first workable leaf node (issue with
no open children). This broke the automation promise of selecting the
actual next issue to work on.

Solution

Added _find_first_leaf() helper method that:

• Recursively traverses down the issue hierarchy
• Finds the first open child at each level (sorted by issue number)
• Returns the issue when no open children exist (leaf node)
• Handles arbitrary nesting depth

The method is called after finding a candidate issue in find_next_issue(),
ensuring both simple and intelligent traversal modes benefit from it.

Testing

Added test_leaf_traversal.py with 4 test cases:

• Descends from parent to first leaf child
• Handles multi-level nesting (grandparent -> parent -> child)
• Returns issue itself when it has no children
• Skips closed children to find first open leaf

All tests pass.

Example

Before: Selects #586 (parent with 8 children)
After: Selects #590 (first leaf child of #586)

• 🩹 fix(pr-feedback): ensure gh extensions install in all auth scenarios

Addresses Copilot review feedback about early exits preventing extension
installation. Refactored to use helper function that installs extensions
immediately after detecting gh authentication, handling both:

• Codespaces (pre-authenticated, exits early)
• Local devcontainer (authenticates with token)

Changes:

• Created install_gh_extensions() helper function
• Call after detecting existing auth (line 48)
• Call after token authentication (line 151)
• Added check for already-installed extensions

• 🩹 fix(sdk): pass is_public query param to API instead of client-side filtering

The prompt list and search methods were doing client-side filtering for
visibility, which returned zero results when scoped to private prompts
because the API only returned public prompts by default.

server-side filtering:

• is_public=true for Visibility::Public

✨ Features

• ✨ feat(cli): implement workspace secrets CLI commands (#523)

• ✨ feat(cli): implement workspace secrets CLI commands

Implements three CLI commands for secure workspace secrets management:

• langstar secrets list: Lists secret keys (values never displayed)
• langstar secrets set: Creates/updates secrets with secure input methods
• langstar secrets delete: Deletes secrets

Security features (per Phase 1.5 requirements):

• Multiple secure input methods: --from-file, --from-env, --interactive, stdin
• NO --value flag (security violation per #488)
• Never outputs secret values in any command output
• Interactive mode uses masked password input (rpassword)

  • Mutual exclusivity tests for input flags
  • Output format option tests

Addresses review comments:

• 🩹 fix(test): format secrets_command_test.rs

• 🩹 fix(test): remove .failure() assertions from format flag tests

The three format flag tests were asserting .failure() expecting the
commands to fail due to missing API credentials. However, in the
integration test environment where LANGSMITH_API_KEY is present, these
commands succeed and return valid results.

Changed assertions to only verify that --format flag parsing works
correctly, without caring about command success/failure. This makes
tests work in both unit and integration environments.

Fixes:

• test_secrets_list_accepts_format_flag
• test_secrets_set_accepts_format_flag
• test_secrets_delete_accepts_format_flag

• 🩹 fix(deps): update rpassword version to match Cargo.lock

Updated Cargo.toml to specify rpassword 7.4 to match the resolved

♻️ Refactoring

• ♻️ refactor(tests): consolidate CLI test fixtures to use SDK directly (#526)

• ♻️ refactor(tests): consolidate CLI test fixtures to use SDK directly

Fixes #524

This refactoring eliminates code duplication between CLI and SDK test
fixtures by creating shared test utilities in the SDK that both can use.

Key changes:

1. Created sdk/src/test_utils.rs - Shared test infrastructure:

   • TestDeploymentConfig - Configuration for test deployments
   • DeploymentGuard - RAII pattern for cleanup on failure
   • wait_for_deployment() - Polls revision status until READY
   • get_or_create_deployment() - Finds existing or creates new

2. Added test-utils feature to SDK - Enables test utilities:

   • Available via langstar-sdk = { features = ["test-utils"] }
   • Guarded by #[cfg(any(test, feature = "test-utils"))]

3. Refactored CLI fixtures to use SDK utilities:

   • Removed CLI shelling (Command::new("langstar")) - uses SDK directly
   • Removed --status READY filter bug - now filters by name
   • Removed LANGGRAPH_GITHUB_INTEGRATION_ID workaround
   • Uses find_integration_for_repo() API for integration discovery

4. Net reduction of ~120 lines by eliminating duplicated logic

Benefits:

• Single source of truth for test fixture logic
• Proper handling of in-progress deployments (fixes race conditions)
• Consistent behavior between SDK and CLI tests
• Easier maintenance - changes only need to be made in one place

• 🩹 fix(tests): use constant deployment name for proper reuse

The get-or-create pattern requires a constant deployment name to
find and reuse existing deployments. Using std::process::id() in
the name caused every test run to create a new deployment since
each process has a unique PID.

Changed from "test-deployment-cli-{pid}" to "test-deployment-cli"
to enable the same behavior as the SDK's "langstar-integration-test".

• ♻️ refactor(tests): unify deployment naming for SDK/CLI tests

Implement consistent naming convention for test deployments:

Changes:

• SDK: Default config uses "pr-integration-test" for deployment reuse
• SDK: Add TestDeploymentConfig::for_release_tests() for lifecycle testing
• CLI: Use SDK default config instead of custom naming
• Cleanup workflow: Target release-* and legacy test-deployment-* patterns
  while preserving pr-integration-test for reuse

• ✨ feat(sdk): implement structured prompt push/pull with schema validation (#420)

• ✨ feat(sdk): implement structured prompt push/pull with schema validation

This commit implements client methods in the SDK to push and pull
structured prompts with JSON schema validation, completing the SDK
layer of the structured output prompts feature.

Changes

SDK Error Types (sdk/src/error.rs)

• Add SchemaValidationError for schema validation failures
• Add InvalidSchemaError for malformed JSON schemas
• Add InvalidMethodError for invalid structured output methods

SDK Dependencies (sdk/Cargo.toml)

• Add jsonschema v0.18 for JSON Schema validation

SDK Prompt Client Methods (sdk/src/prompts.rs)

• Add push_structured_prompt() - Validates and pushes StructuredPrompt
• Add pull() - Retrieves prompt commit manifest
• Add pull_structured_prompt() - Pulls and deserializes StructuredPrompt
• Add validate_json_schema() - Validates JSON Schema before push
• Add validate_method() - Validates structured output method

Comprehensive Unit Tests

• Schema validation tests (valid/invalid/malformed schemas)
• Method validation tests (json_schema/function_calling/invalid)
• Serialization tests for API compatibility
• Deserialization tests for pull operations

Implementation Details

• Schema validation uses jsonschema crate for compile-time validation
• Methods validated: "json_schema" and "function_calling"
• StructuredPrompt serialized to LC-JSON format matching Python SDK
• Client-side validation prevents invalid schemas from reaching API
• Error messages provide clear guidance for validation failures

Testing

• ✅ cargo fmt - Passed
• ✅ cargo check --workspace --all-features - Passed
• ✅ cargo clippy --workspace --all-features -- -D warnings - Passed
• ✅ Unit tests added for all new functionality

Fixes #406

• 🩹 fix(sdk): remove unused SchemaValidationError variant

The SchemaValidationError variant was defined but never used in the
codebase. InvalidSchemaError is used instead and is more descriptive
for the actual use case.

Addresses Copilot review feedback.

• ✨ feat(cli): add structured prompt support with --schema flag (#431)

• ✨ feat(cli): add structured prompt support with --schema flag

Implements CLI commands for structured output prompts with JSON schema support:

• Add --schema and --schema-method flags to prompt push

  • Validates JSON Schema files before pushing
  • Supports json_schema and function_calling methods
  • Automatically detects regular vs structured prompts

• Add new prompt pull command

  • Downloads prompt manifests from PromptHub
  • Detects and displays structured prompt schemas
  • Shows input variables, method, and template

• Validation and error handling

  • Schema file validation using jsonschema crate
  • Clear error messages for invalid schemas
  • Method validation (json_schema/function_calling)

Design follows DX consistency analysis from issue #403:

• Uses --schema FILE pattern (matches dataset import)
• Defaults to json_schema method
• Backward compatible with existing prompt push
