agentic_tools 0.1.0

Tool and function-calling layer for the agentic framework: a typed tool contract, JSON Schema argument validation, a tool registry with namespacing, permission gating, timeouts and structured results. [...]

Changelog

0.1.0

Initial release of the tool layer.

Added

• Contract — Tool, ToolSpec, ToolInvocation and ToolResult, with specifications validated at construction against the naming rules every major provider enforces.
• Authoring — FunctionTool for closure-backed tools, FunctionTool.text for the simplest case, DelegatingTool for cross-cutting behaviour by composition, and RenamedTool for resolving naming collisions between packages.
• Registry — ToolRegistry with eager and lazy registration, and ToolSet for handing each agent only the tools it needs. Specs are readable without constructing implementations.
• Execution — ToolExecutor performing argument repair and validation, human-approval gating that fails closed, per-tool time budgets enforced even against uncooperative tools, cancellation, bounded-concurrency batches with serialised writes, and tracing.
• Events — ToolCallStarted, ToolCallCompleted and ToolApprovalRequested, with a ToolFailureKind category on every failure.
