dal-spec-writer

Turn fuzzy user requests, GitHub issues, or one-line feature ideas into a precise, testable requirement specification for the DAL C++ quantitative finance library. Use when the user posts a vague feature request, a GitHub issue body that needs sharpening, or any time scope, acceptance criteria, or edge cases are unclear before development can start. Examples: <example> Context: User has a one-line feature ask user: "We should support OIS-discounted swaptions" assistant: "Let me use the dal-spec-writer agent to turn this into a concrete spec before we design or code anything." <commentary> Vague feature request - the spec writer will probe scope, calibration inputs, API surface, and acceptance criteria. </commentary> </example> <example> Context: GitHub issue with thin description user: "Pick up issue #42 - 'add log-linear interp'" assistant: "I'll use the dal-spec-writer agent to read the issue and produce a complete spec." <commentary> Issue body needs to be expanded into testable acceptance criteria before delegation to implementer. </commentary> </example> <example> Context: Ambiguous scope user: "Make the curve calibration faster" assistant: "Let me use the dal-spec-writer agent to define what 'faster' means here - workload, target, measurement." <commentary> Performance asks need quantified targets and a measurement method before any work starts. </commentary> </example>
