When parsing result types from empty input, the parser now returns a default value instead of panicking. This change ensures robust handling of edge cases where no data is provided, preventing runtime crashes and improving the library's reliability in production use.

The result parser now returns an empty vector instead of panicking when given an empty input string, making the function robust against edge cases where no data is provided. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Fix an integer overflow bug in the parsing logic that caused incorrect results when processing numeric values exceeding the maximum representable range. The issue was resolved by adding a bounds check before arithmetic operations to ensure safe conversion. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Removed an unused import of HashMap from the standard library's collections module to clean up the code and eliminate a compiler warning about unused imports. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The `Policy` struct in the policy types module was no longer referenced anywhere in the codebase, so it has been removed to eliminate dead code and reduce maintenance overhead. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
When the policy file does not exist, the module now returns an empty policy instead of panicking. This allows the application to continue with default behavior when no policy has been configured. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
When a struct field lacks an explicit type annotation, the tool now correctly falls back to the inferred type instead of failing with an error. This resolves a regression where previously valid code without type annotations was rejected. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The test assertion was updated to reflect the corrected return value from the result function, ensuring the test validates the expected output after the behavior change. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Changed the test assertion to use the standard `assert_eq!` macro instead of a custom comparison, ensuring consistency with the project's testing conventions and improving readability of test output. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The test helper function now returns an empty result instead of panicking when given an empty input string, ensuring consistent behavior across all test cases. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The test was previously asserting that a successful result was returned when the error variant should have been expected. This change corrects the assertion to properly validate the error case, ensuring the test accurately reflects the intended behavior. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Updated the test assertion to reflect the corrected policy enforcement logic, ensuring the test validates the intended behavior rather than the previous incorrect expectation. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

The test assertion was inverted, causing the test to pass when the policy evaluation returned an unexpected result. This change fixes the assertion to correctly validate the expected behavior. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Updated the test assertion to properly validate the expected behavior of policy evaluation, ensuring the test correctly reflects the intended logic rather than checking an incorrect condition. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
When a test name is empty, the test runner now skips the test instead of attempting to run it. This prevents a panic that occurred when the test name was used in string operations without first checking for emptiness. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The test was failing because it still called the old function signature with three arguments. Updated the call to match the refactored API that now takes a single configuration struct. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

In `@crates/tinytools/src/policy/types.rs`:
- Line 141: Update the public ToolRuntime change involving the replay field to
preserve source compatibility for external struct literals by moving replay
metadata behind an existing compatible extension point; if that is not possible,
explicitly classify and document the release as a breaking API change rather
than treating the field addition as additive.
In `@crates/tinytools/src/result/types.rs`:
- Around line 349-350: Change ToolControl’s return_direct field to Option<bool>
with serde defaulting and omission when None, preserving the unset state for
calls created by with_goto() and with_state_update(). Update return_direct() to
set Some(true), and add a separate builder that sets Some(false) so callers can
explicitly disable the tool’s static declaration.
- Around line 44-68: Because adding fields to the public ToolResult struct
breaks existing Rust struct literals, apply the required pre-1.0 minor version
bump from 0.2.0 to 0.3.0 across the package/workspace release metadata. Keep the
new follow_up, metadata, control, and error_kind fields unchanged; do not
address unrelated ToolRuntime changes.

The error type in the result module now derives the standard Error trait, enabling it to be used with generic error handling patterns and the `?` operator in contexts that require `dyn Error`. This improves interoperability with the broader Rust ecosystem. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
When parsing type annotations from empty input, the parser now returns an empty result instead of panicking. This fixes a crash that occurred when the type string was missing or blank, ensuring robust handling of edge cases in type inference. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Changed the test assertion to use `assert_eq!` instead of `assert!` for comparing the result value, making the test failure message more informative by showing both the expected and actual values. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
