build
Use when developing a major feature: research the project, create a phased implementation plan, track progress and verify phase outcomes before declaring completion.
Why this skill is useful
Adds a structured workflow for managing feature development phases that the AI wouldn't reliably generate on its own.

What this skill does
Feature development pipeline - research, plan, track, and implement major features. Detailed Guide Read the detailed guide before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely. When to Use You need a structured workflow for building a major feature across research, planning, implementation, and tracking. The task involves moving a feature through named phases such as research, implementation, progress, or phase. You want one command to coordinate status, next steps, and phased delivery for a feature effort. Example Input: /build status export-csv for an authorized project whose implementation plan exists but whose CSV encoding test is still failing. Output: implementation in progress, failed encoding test and the next repair step; the presence of three planning files does not justify claiming the feature is complete. With no slash command support, interpret “show the status of export-csv” the same way. Limitations Use this skill only when the task clearly matches the scope described above. Do not treat the output as a substitute for environment-specific validation, testing, or expert review. Validate feature IDs and destination containment before writing. Host-specific command and question tools are optional interfaces, not prerequisites. Read-only status/research does not authorize deployment; existing plans and unrelated work must be preserved.
