+> Shared type definitions for MCP server configuration, token weights, and workflow input parameters — used across multiple `gh-aw` packages to avoid circular imports.
 
 ## Overview
 
-This package defines common data structures that are shared between the `parser` and `workflow` packages. Centralizing these types here allows both packages to reference the same definitions without creating import cycles.
+This package defines common data structures shared between the `parser` and `workflow` packages. Centralizing these types in a dedicated package allows both to reference the same definitions without creating import cycles.
+
+The primary types are `BaseMCPServerConfig` (the foundation for all MCP server configurations), `MCPAuthConfig` (OIDC authentication for HTTP MCP servers), `TokenWeights` with `TokenClassWeights` (AI Credits cost ratio configuration), and `InputDefinition` (workflow dispatch input parameters following the GitHub Actions schema).
+
+All struct fields carry both `json` and `yaml` struct tags, ensuring types can be round-tripped through both serialization formats. `BaseMCPServerConfig` is designed to be embedded rather than used directly — consumer packages (`parser`, `workflow`) add domain-specific fields and validation on top of the shared base.

 # typeutil Package
 
-The `typeutil` package provides general-purpose type conversion utilities for working with heterogeneous `any` values, particularly those arising from JSON and YAML parsing.
+> General-purpose type conversion utilities for heterogeneous `any` values, particularly those arising from JSON and YAML parsing.
 
 ## Overview
 
 JSON and YAML parsers produce `any` values whose concrete type varies at runtime (`int`, `float64`, `string`, etc.). This package provides safe, well-documented conversion functions that handle the common cases without requiring callers to write their own type switches.
 
+Functions are grouped into three categories: **strict conversions** (return a `(value, ok)` pair to distinguish zero from missing/invalid), **safe overflow conversions** (clamp to zero on overflow instead of panicking), and **lenient conversions** (also handle string inputs, returning zero on failure). A separate group handles token-limit strings with optional `K`/`M` multiplier suffixes.
+
+Choose the right category based on the source: use strict conversions for YAML config fields where the YAML library has already typed the value; use lenient conversions for heterogeneous sources such as JSON metrics or log-parsed data where a zero default on failure is acceptable.
