Move host-independent tool helpers from OpenHuman into tinyagents-harness - #228
Conversation
Moved from OpenHuman agent/tinyagents/tools.rs with its tests. Co-authored-by: Medulla <medulla@tinyhumans.ai>
Moved from OpenHuman agent/harness/required_output.rs with its tests. Co-authored-by: Medulla <medulla@tinyhumans.ai>
The schema walk implementation now correctly processes optional fields by checking for the `null` type in a field's type list. Previously, optional fields were skipped during schema traversal, which caused tool harness to miss valid optional parameters and fail to generate proper test data for them. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Moved from OpenHuman json_schema/ops.rs with its tests. Co-authored-by: Medulla <medulla@tinyhumans.ai>
The time parsing logic previously required seconds to be present in the input string, causing failures for valid time formats like "14:30". This change makes the seconds field optional, allowing the parser to accept both "HH:MM" and "HH:MM:SS" formats while defaulting missing seconds to zero. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The time parsing logic was updated to properly resolve ambiguous date formats where day and month values could be swapped. This change ensures that dates like "03/04/2024" are interpreted consistently according to the expected locale, preventing incorrect date resolution in tool invocations. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Split the parser into time_parse.rs and add durations like 2h30m, calendar phrases (tomorrow at 9am, since Monday, next Friday at 3:30 pm), clock times, date plus clock time, and time-first forms, with an injectable now for tests. Ported from OpenHuman resolve_time.rs; the payload shape is unchanged. Co-authored-by: Medulla <medulla@tinyhumans.ai>
Consolidated the nested `if` and `if let` into a single `if let` guard expression, making the control flow clearer without changing behaviour. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Replaced a nested `if let` with a single `if let` chain using `&&` to combine the pattern match and the boolean condition, making the control flow flatter and easier to read without changing any behaviour. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

- Line 39: Update compute_primary_array_path to recognize “array” when a
schema’s type is an array containing multiple type names, while preserving
support for a string type; add test coverage for a nullable array property
returning its path.
- Around line 201-204: Update the unsupported-name filter in the schema-walking
logic to account for names allowed by matching patternProperties and
schema-valued additionalProperties, not just properties. Keep rejecting names
disallowed by additionalProperties: false, and anchor the change to the args_obj
filter.
- Around line 142-145: Update the fallback in the schema-walking logic to return
unlisted keys only when the input is identifiable as a legacy field map; for
JSON Schema objects such as those containing "type", "$id", or "$defs", do not
treat metadata keywords as response fields. Preserve the existing legacy-key
fallback for legacy field maps.

Extend CurrentTimeTool and ResolveTimeTool to optionally render their results as compact markdown lists when the caller requests markdown output via ToolCallOptions. This allows agents that prefer human-readable formatted responses to receive structured time information without needing to parse raw JSON. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Add test coverage verifying that all time tools are marked as read-only and support markdown output. Also add tests for the `CurrentTimeTool` and `ResolveTimeTool` to confirm that markdown rendering is only produced when explicitly requested via `prefer_markdown()`, and that the rendered output contains the expected fields. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Every goal control now returns a JSON payload with `goal` and `text` fields, replacing the previous split between markdown content and a separate raw value. A new `GoalUpdateHook` callback lets hosts observe writes from `goal_set`, `goal_complete`, `goal_pause`, and `goal_resume`. The tool also reports its permission level as read-only or write based on the control kind, and error messages are simplified for clarity.

The import of `Result` from `tinyagents_harness::error` was unused in this file, so it has been removed to keep the code clean and avoid compiler warnings. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
…yload/hook
Time tools: CurrentTimeTool and ResolveTimeTool now override
execute_with_options, render a markdown form when prefer_markdown is set,
report supports_markdown, return pretty-printed JSON text, log at debug, and
use the longer 'expr is required' hint OpenHuman shipped.
Goal tools: every control answers with {goal, text} (goal null when absent),
attaches text as markdown, reports Write permission for mutating controls,
surfaces store and argument errors as error results, and exposes
GoalTool::with_update_hook so a host can publish an event after a write.
The goal_set description regains the usage guidance and budget wording.

When a user-renamed title happens to match this loose pattern, such as Chat API 2 3:00 PM, this function returns true because it accepts any three ASCII letters as the month; it likewise accepts out-of-range days, hours, and minutes. Callers may consequently overwrite a custom title even though the API promises that only generated placeholders are eligible, so validate the actual generated month names and numeric ranges.

Add test for store-error path in goal tool dispatch
Every store::* call in dispatch now maps errors to strings via map_err(stringify) and returns them as tool errors (Err(String)). This is a behavioral change from the previous ? propagation (which would surface as an anyhow::Error and likely abort the run). However, the existing tests use an in-memory store that never fails, so the new error-handling path is never exercised. Add a test with a mock/failing store to verify that store errors produce a tool error (not a panic or abort) with a readable message.
