Feb 1, 2026February 2026: Two core feature upgrades for coda/packs-sdk focused on reliability, developer ergonomics, and validation. Implemented ChatSkill API robustness with validation tests for chatSkill configurations, support for partial skill definitions in API methods, and a refactor replacing ChatSkillDef with PartialSkillDef, including docs and default tools behavior. Upgraded the validation stack to Zod v4, addressed migration issues, expanded unit tests, and strengthened error handling. These changes reduce misconfigurations, enable safer partial overrides, and lay a solid foundation for future skill extensibility, delivering measurable business value via fewer support incidents, faster development cycles, and more reliable end-user experiences.

Jan 1, 2026January 2026 monthly summary for coda/packs-sdk: Three high-impact initiatives delivered to broaden AI capabilities, improve reliability, and expose new tooling for developers. Skill Models support enables OpenAI integration within the SDK by flattening the SkillModel enum, deriving upload-validation values, and exposing OpenAI models. A new WebSearch tool type and public API exposure expands agent capabilities to perform public internet searches and makes the WebSearchTool available in the public API. Duplicate tool validation was added to ensure correctness in skill definitions by detecting duplicates through deep equality checks and normalized ordering, accompanied by refactors and unit tests. These efforts collectively increase platform value for customers, reduce configuration errors, and strengthen the SDK's API surface.
