msd-core/gsd-core/workflows/spec-phase.md

Clarify WHAT a phase delivers through a Socratic interview loop with quantitative ambiguity scoring. Produces a SPEC.md with falsifiable requirements that discuss-phase treats as locked decisions.

This workflow handles "what" and "why" — discuss-phase handles "how".

<ambiguity_model> Score each dimension 0.0 (completely unclear) to 1.0 (crystal clear):

Dimension	Weight	Minimum	What it measures
Goal Clarity	35%	0.75	Is the outcome specific and measurable?
Boundary Clarity	25%	0.70	What's in scope vs out of scope?
Constraint Clarity	20%	0.65	Performance, compatibility, data requirements?
Acceptance Criteria	20%	0.70	How do we know it's done?

Ambiguity score = 1.0 − (0.35×goal + 0.25×boundary + 0.20×constraint + 0.20×acceptance)

Gate: ambiguity ≤ 0.20 AND all dimensions ≥ their minimums → ready to write SPEC.md.

A score of 0.20 means 80% weighted clarity — enough precision that the planner won't silently make wrong assumptions. </ambiguity_model>

<interview_perspectives> Rotate through these perspectives — each naturally surfaces different blindspots:

Researcher (rounds 1–2): Ground the discussion in current reality.

• "What exists in the codebase today related to this phase?"
• "What's the delta between today and the target state?"
• "What triggers this work — what's broken or missing?"

Simplifier (round 2): Surface minimum viable scope.

• "What's the simplest version that solves the core problem?"
• "If you had to cut 50%, what's the irreducible core?"
• "What would make this phase a success even without the nice-to-haves?"

Boundary Keeper (round 3): Lock the perimeter.

• "What explicitly will NOT be done in this phase?"
• "What adjacent problems is it tempting to solve but shouldn't?"
• "What does 'done' look like — what's the final deliverable?"

Failure Analyst (round 4): Find the edge cases that invalidate requirements.

• "What's the worst thing that could go wrong if we get the requirements wrong?"
• "What does a broken version of this look like?"
• "What would cause a verifier to reject the output?"

Seed Closer (rounds 5–6): Lock remaining undecided territory.

• "We have [dimension] at [score] — what would make it completely clear?"
• "The remaining ambiguity is in [area] — can we make a decision now?"
• "Is there anything you'd regret not specifying before planning starts?" </interview_perspectives>

Parse JSON for: phase_found, phase_dir, phase_number, phase_name, phase_slug, padded_phase, state_path, requirements_path, roadmap_path, planning_path, response_language, commit_docs.

If response_language is set: All user-facing text in this workflow MUST be in {response_language}. Technical terms, code, and file paths stay in English.

If phase_found is false:

Phase [X] not found in roadmap.
Use /gsd:progress to see available phases.

Exit.

Check for existing SPEC.md:

ls ${phase_dir}/*-SPEC.md 2>/dev/null | grep -v AI-SPEC | head -1 || true

If SPEC.md already exists:

If --auto: Auto-select "Update it". Log: [auto] SPEC.md exists — updating.

Otherwise: Use AskUserQuestion:

• header: "Spec"
• question: "Phase [X] already has a SPEC.md. What do you want to do?"
• options:
  • "Update it" — Revise and re-score
  • "View it" — Show current spec
  • "Skip" — Exit (use existing spec as-is)

If "View": Display SPEC.md, then offer Update/Skip. If "Skip": Exit with message: "Existing SPEC.md unchanged. Run /gsd:discuss-phase [X] to continue." If "Update": Load existing SPEC.md, continue to Step 3.

Step 2: Scout Codebase

Read these files before any questions:

• {requirements_path} — Project requirements
• {state_path} — Decisions already made, current phase, blockers
• ROADMAP.md phase entry — Phase description, goals, canonical refs

Grep the codebase for code/files relevant to this phase goal. Look for:

• Existing implementations of similar functionality
• Integration points where new code will connect
• Test coverage gaps relevant to the phase
• Prior phase artifacts (SUMMARY.md, VERIFICATION.md) that inform current state

Synthesize current state — the grounded baseline for the interview:

• What exists today related to this phase
• The gap between current state and the phase goal
• The primary deliverable: what file/behavior/capability does NOT exist yet?

Confirm your current state synthesis internally. Do not present it to the user yet — you'll use it to ask precise, grounded questions.

Step 3: First Ambiguity Assessment

Before questioning begins, score the phase's current ambiguity based only on what ROADMAP.md and REQUIREMENTS.md say:

Goal Clarity:       [score 0.0–1.0]
Boundary Clarity:   [score 0.0–1.0]
Constraint Clarity: [score 0.0–1.0]
Acceptance Criteria:[score 0.0–1.0]

Ambiguity: [score] ([calculate])

If --auto and initial ambiguity already ≤ 0.20 with all minimums met: Skip interview — derive SPEC.md directly from roadmap + requirements. Log: [auto] Phase requirements are already sufficiently clear — generating SPEC.md from existing context. Jump to Step 6.

Otherwise: Continue to Step 4.

Step 4: Socratic Interview Loop

Max 6 rounds. Each round: 2–3 questions max. End round after user responds.

Round selection by perspective:

• Round 1: Researcher
• Round 2: Researcher + Simplifier
• Round 3: Boundary Keeper
• Round 4: Failure Analyst
• Rounds 5–6: Seed Closer (focus on lowest-scoring dimensions)

After each round:

1. Update all 4 dimension scores from the user's answers
2. Calculate new ambiguity score
3. Display the updated scoring:

After round [N]:
  Goal Clarity:       [score] (min 0.75) [✓ or ↑ needed]
  Boundary Clarity:   [score] (min 0.70) [✓ or ↑ needed]
  Constraint Clarity: [score] (min 0.65) [✓ or ↑ needed]
  Acceptance Criteria:[score] (min 0.70) [✓ or ↑ needed]
  Ambiguity: [score] (gate: ≤ 0.20)

Gate check after each round:

If gate passes (ambiguity ≤ 0.20 AND all minimums met):

If --auto: Jump to Step 6.

Otherwise: AskUserQuestion:

• header: "Spec Gate Passed"
• question: "Ambiguity is [score] — requirements are clear enough to write SPEC.md. Proceed?"
• options:
  • "Yes — write SPEC.md" → Jump to Step 6
  • "One more round" → Continue interview
  • "Done talking — write it" → Jump to Step 6

If max rounds reached (6) and gate not passed:

If --auto: Write SPEC.md anyway — flag unresolved dimensions. Log: [auto] Max rounds reached. Writing SPEC.md with [N] dimensions below minimum. Planner will need to treat these as assumptions.

Otherwise: AskUserQuestion:

• header: "Max Rounds"
• question: "After 6 rounds, ambiguity is [score]. [List dimensions still below minimum.] What would you like to do?"
• options:
  • "Write SPEC.md anyway — flag gaps" → Write SPEC.md, mark unresolved dimensions in Ambiguity Report
  • "Keep talking" → Continue (no round limit from here)
  • "Abandon" → Exit without writing

If --auto mode throughout: Replace all AskUserQuestion calls above with Claude's recommended choice. Log decisions inline. Apply the same logic as --auto in discuss-phase.

Text mode (workflow.text_mode: true or --text flag): Use plain-text numbered lists instead of AskUserQuestion TUI menus.

Step 5: (covered inline — ambiguity scoring is per-round)

Step 5.5: Edge-Completeness Probe

Run AFTER the ambiguity gate passes (you probe edges of clear requirements, not vague ones). Reference: @~/.claude/gsd-core/references/edge-probe.md.

Runtime coverage compute — resolve and invoke edge-probe.cjs:

# Resolve the compiled edge-probe.cjs against the GSD install dir via RUNTIME_DIR (#448)
# — NOT the consuming project's git root — falling back to git toplevel / $HOME/.claude.

if [ "$APPLICABLE" = "0" ]; then
  echo "WARNING: edge-probe proposed ZERO applicable edges across all requirements — likely a classification miss or malformed requirements, not a genuinely edge-free spec. Do NOT silently write an empty Edge Coverage section." >&2
fi

If $APPLICABLE is 0, do NOT proceed silently: ask the author to confirm via AskUserQuestion ("The edge probe found no applicable edges for any requirement — is this genuinely an edge-free spec, or should we revisit the requirement wording / authored shapes?"). Only write an empty ## Edge Coverage section after explicit confirmation.

For each Requirement gathered so far:

1. Classify its shape and raise only applicable edge categories (relevance filter — see the taxonomy in the reference). Reuse any edges the Round-4 Failure Analyst already surfaced as pre-covered.
2. For each raised category, propose a CONCRETE candidate edge (not "consider boundaries" — e.g. "R2 merges intervals; what about [[1,2],[2,3]] that only touch?").
3. Resolve each with the user (AskUserQuestion; text mode → numbered list):
   • Specify it → write a new pass/fail line into Acceptance Criteria AND mark the edge covered.
   • Dismiss (reason) → mark dismissed with a required non-empty reason.
   • Backstop with a test → mark backstop; note "held-out edge test" for plan-phase.
   • Defer → leave unresolved.

Soft gate (after resolving):

• All applicable edges resolved → proceed to Step 6.
• Any unresolved → AskUserQuestion:
  • header: "Edge Coverage"
  • question: "[N] edge(s) are unresolved: [list]. What do you want to do?"
  • options: "Resolve now" (loop back) / "Write SPEC.md anyway — flag unresolved" / "Keep probing"
  • On "anyway": write SPEC.md with those rows marked ⚠ Edge unresolved — planner must treat as assumption.

--auto mode: auto-covered where a defensible acceptance criterion can be written; otherwise auto-backstop (never auto-dismiss — a wrong dismissal is the exact silent failure being eliminated). Log: [auto] edge coverage: C covered, B backstop, U unresolved.

Populate the ## Edge Coverage section of SPEC.md from the resolved edges.

Step 6: Generate SPEC.md

Use the SPEC.md template from @~/.claude/gsd-core/templates/spec.md.

• Populate the Edge Coverage section from Step 5.5 (covered/dismissed/backstop/unresolved rows).

Requirements for every requirement entry:

• One specific, testable statement
• Current state (what exists now)
• Target state (what it should become)
• Acceptance criterion (how to verify it was met)

Vague requirements are rejected:

• ✗ "The system should be fast"
• ✗ "Improve user experience"
• ✓ "API endpoint responds in < 200ms at p95 under 100 concurrent requests"
• ✓ "CLI command exits with code 1 and prints to stderr on invalid input"

Count requirements. The display in discuss-phase reads: "Found SPEC.md — {N} requirements locked."

Boundaries must be explicit lists:

• "In scope" — what this phase produces
• "Out of scope" — what it explicitly does NOT do (with brief reasoning)

Acceptance criteria must be pass/fail checkboxes — no "should feel good" or "looks reasonable."

If any dimensions are below minimum, mark them in the Ambiguity Report with: ⚠ Below minimum — planner must treat as assumption.

Write to: {phase_dir}/{padded_phase}-SPEC.md

Step 7: Commit

git add "${phase_dir}/${padded_phase}-SPEC.md"
git commit -m "spec(phase-${phase_number}): add SPEC.md for ${phase_name} — ${requirement_count} requirements (#2213)"

If commit_docs is false: Skip commit. Note that SPEC.md was written but not committed.

Step 8: Wrap Up

Display:

SPEC.md written — {N} requirements locked.

  Phase {X}: {name}
  Ambiguity: {final_score} (gate: ≤ 0.20)

Next: /gsd:discuss-phase {X}
  discuss-phase will detect SPEC.md and focus on implementation decisions only.

<critical_rules>

• Every requirement MUST have current state, target state, and acceptance criterion
• Boundaries section is MANDATORY — cannot be empty
• "In scope" and "Out of scope" must be explicit lists, not narrative prose
• Acceptance criteria must be pass/fail — no subjective criteria
• SPEC.md is NEVER written if the user selects "Abandon"
• Do NOT ask about HOW to implement — that is discuss-phase territory
• Scout the codebase BEFORE the first question — grounded questions only
• Max 2–3 questions per round — do not frontload all questions at once
• Step 5.5 edge probe runs after the ambiguity gate; dismissals require a reason; --auto never auto-dismisses </critical_rules>

<success_criteria>

• Codebase scouted and current state understood before questioning
• All 4 dimensions scored after every round
• Gate passed OR user explicitly chose to write despite gaps
• SPEC.md contains only falsifiable requirements
• Boundaries are explicit (in scope / out of scope with reasoning)
• Acceptance criteria are pass/fail checkboxes
• SPEC.md committed atomically (when commit_docs is true)
• User directed to /gsd:discuss-phase as next step
• Edge-completeness probe run; Edge Coverage section populated; unresolved edges flagged as assumptions </success_criteria>
