Spec Pack Normalizer

• Durable facts: what is being built, why, for whom
• Constraints: platform, runtime, model, process, integration
• Desired outcomes: goals and success criteria
• Explicit non-goals: what is NOT being built
• Stated preferences: stack choices, model choices, tooling

Separate facts from assumptions. Mark each clearly.

3. Identify contradictions and ambiguities

• Resolve obvious duplication by preferring the most specific or latest source
• Do NOT smooth over meaningful disagreements — call them out
• Create a batched decision packet for all blocking ambiguities:
  • Blocking: choices that materially change implementation (stack, provider, model, architecture)
  • Non-blocking: open questions that don't prevent the first execution wave

4. Present the decision packet

Present ALL blocking ambiguities to the user at once. Do not ask one at a time. Include:

• What the ambiguity is
• What the options are (if known)
• What the implications of each option are
• Which option you recommend and why (if you have enough information)

Wait for user decisions before proceeding.

5. Write the canonical brief

Write to docs/spec/CANONICAL-BRIEF.md (or docs/BRIEF.md for simpler repos).

Required sections (all 12 must be present):

1. Project Summary — one paragraph, what and why
2. Goals — flat bullet list of desired outcomes
3. Non-Goals — flat bullet list of explicit exclusions
4. Constraints — platform, runtime, model, process, integration
5. Required Outputs — repo structure, docs, agent/tool outputs, validation
6. Tooling and Model Constraints — provider, models, runtime, host
7. Canonical Truth Map — which file owns which kind of state
8. Blocking Decisions — resolved choices from the decision packet
9. Non-Blocking Open Questions — things that don't block the first wave
10. Backlog Readiness — whether ticketing can proceed, which areas are blocked
11. Acceptance Signals — what must be true for the result to be usable
12. Assumptions — non-blocking assumptions that don't silently decide major behavior

6. Validate

Verify the brief:

• All 12 sections are present and non-empty
• Facts and assumptions are separated
• Blocking decisions are all resolved (or explicitly recorded as blocked)
• Backlog readiness clearly states whether the first execution wave can be detailed
• Exact product names, provider strings, and model identifiers are preserved
• Brief is concise enough for weaker models to load

Output contract

A single CANONICAL-BRIEF.md file containing all 12 sections, plus a decision packet log if ambiguities were resolved during the run.

Rules

• Prefer opportunistic intake over rigid required input structure
• Do not invent implementation detail for work that depends on unresolved choices
• Do not hide contradictions — call them out in Open Questions
• Keep the brief concise enough for weaker models to load
• Preserve exact names, providers, and model strings when specified
• Separate facts from assumptions explicitly

Failure handling

• No source material found: Stop. Request minimum viable input (problem statement + target users + rough scope)
• Contradictions between sources: Call out in Open Questions; do not silently pick a winner
• Source material is a single vague paragraph: Extract what exists, mark everything else as Open Questions, present decision packet
• Too many blocking decisions: Prioritize by impact; present the top 3-5 most critical first
