gsd-research-phase by vamseeachanta/workspace-hub

See references/codex-adapter.md for the Codex skill adapter (AskUserQuestion/Task mapping).

Note: This is a standalone research command. For most workflows, use $gsd-plan-phase which integrates research automatically.

Use this command when:

You want to research without planning yet
You want to re-research after planning is complete
You need to investigate before deciding if a phase is feasible

Orchestrator role: Parse phase, validate against roadmap, check existing research, gather context, spawn researcher agent, present results.

Why subagent: Research burns context fast (WebSearch, Context7 queries, source verification). Fresh 200k context for investigation. Main context stays lean for user interaction.

Normalize phase input in step 0 before any directory lookups.

0. Initialize Context

INIT=$(node "/mnt/local-analysis/workspace-hub/.codex/get-shit-done/bin/gsd-tools.cjs" init phase-op "{{GSD_ARGS}}")
if [[ "$INIT" == @file:* ]]; then INIT=$(cat "${INIT#@file:}"); fi

Extract from init JSON: phase_dir, phase_number, phase_name, phase_found, commit_docs, has_research, state_path, requirements_path, context_path, research_path.

Resolve researcher model:

RESEARCHER_MODEL=$(node "/mnt/local-analysis/workspace-hub/.codex/get-shit-done/bin/gsd-tools.cjs" resolve-model gsd-phase-researcher --raw)

1. Validate Phase

PHASE_INFO=$(node "/mnt/local-analysis/workspace-hub/.codex/get-shit-done/bin/gsd-tools.cjs" roadmap get-phase "${phase_number}")

If found is false: Error and exit. If found is true: Extract phase_number, phase_name, goal from JSON.

2. Check Existing Research

ls .planning/phases/${PHASE}-*/RESEARCH.md 2>/dev/null

If exists: Offer: 1) Update research, 2) View existing, 3) Skip. If doesn't exist: Continue.

3. Gather Phase Context

Use paths from INIT (do not inline file contents in orchestrator context):

requirements_path
context_path
state_path

Present summary with phase description and what files the researcher will load.

4. Spawn gsd-phase-researcher Agent

Research modes: ecosystem (default), feasibility, implementation, comparison.

See references/researcher-prompt.md for the full researcher agent prompt template.

Task(
  prompt=filled_prompt,
  subagent_type="gsd-phase-researcher",
  model="{researcher_model}",
  description="Research Phase {phase}"
)

5. Handle Agent Return

## RESEARCH COMPLETE: Display summary, offer: Plan phase, Dig deeper, Review full, Done.

## CHECKPOINT REACHED: Present to user, get response, spawn continuation.

## RESEARCH INCONCLUSIVE: Show what was attempted, offer: Add context, Try different mode, Manual.

6. Spawn Continuation Agent

See references/researcher-prompt.md for the continuation prompt template.

Task(
  prompt=continuation_prompt,
  subagent_type="gsd-phase-researcher",
  model="{researcher_model}",
  description="Continue research Phase {phase}"
)
