From GSD Core
Guides structured phase discussion to extract implementation decisions, gray areas, and locked choices. Adaptively questions the user, scouts codebase for reusable assets, and produces a CONTEXT.md for research and planning agents.

The summary Claude sees in its skill listing — used to decide when to auto-load this skill
<objective>
How it works:
Output: {phase_num}-CONTEXT.md — decisions clear enough that downstream agents can act without asking the user again
<execution_context> Workflow files are loaded on-demand in the section below — not upfront. Do not pre-load any workflow files before reading the mode routing instructions. </execution_context>
<runtime_note>
Copilot (VS Code): Use vscode_askquestions wherever this workflow calls AskUserQuestion. They are equivalent — vscode_askquestions is the VS Code Copilot implementation of the same interactive question API.
</runtime_note>
Context files are resolved in-workflow using init phase-op and roadmap/state tool calls.
If --assumptions is in $ARGUMENTS:
Read and execute ~/.claude/gsd-core/workflows/list-phase-assumptions.md end-to-end.
Stop here.
Otherwise, if DISCUSS_MODE is "assumptions":
Read and execute ~/.claude/gsd-core/workflows/discuss-phase-assumptions.md end-to-end.
Otherwise ("discuss" / unset / any other value):
Read and execute ~/.claude/gsd-core/workflows/discuss-phase.md end-to-end.
MANDATORY: Read the appropriate workflow file BEFORE taking any action. The objective and success_criteria sections in this command file are summaries — the workflow file contains the complete step-by-step process with all required behaviors, config checks, and interaction patterns. Do not improvise from the summary.
Lazy loading: templates/context.md is loaded inside the write_context step of the active workflow. discuss-phase-power.md is loaded inside discuss-phase.md when --power is detected. Do not load either here.
<success_criteria>
npx claudepluginhub open-gsd/gsd-coreDiscusses planning phases to identify ambiguities, capture decisions in CONTEXT.md, and lock them before plan generation. Supports phase numbers or --project mode.
Identifies gray areas in tasks (UI layouts, API formats, CLI flags), collects user decisions via multiple-choice questions, generates CONTEXT.md for downstream agents.
Clarifies phase requirements through structured Socratic questioning with quantitative ambiguity scoring, producing a SPEC.md before discuss-phase.
