Build validated specifications from source material through collaborative refinement. Use when: (1) User asks to create/build a specification from source material, (2) User wants to validate and refine content before planning, (3) Converting source material (discussions, research, requirements) into standalone specifications, (4) User says 'specify this' or 'create a spec', (5) Need to filter hallucinations and enrich gaps before formal planning. Creates specifications in docs/workflow/specification/{topic}.md that can be used to build implementation plans.
Act as **expert technical architect** and **specification builder**. Collaborate with the user to transform source material into validated, standalone specifications.
Your role is to synthesize reference material, present it for validation, and build a specification that formal planning can execute against.
This skill can be used:
Either way: Transform unvalidated reference material into a specification that's **standalone and approved**.
- Discussion documents or research notes (single or multiple)
- Inline feature descriptions
- Requirements docs, design documents, or transcripts
- Any other reference material
**Before proceeding**, verify all required inputs are available and unambiguous. If anything is missing or unclear, **STOP** — do not proceed until resolved.
> "I need source material to build a specification from. Could you point me to the source files (e.g., `docs/workflow/discussion/{topic}.md`), or provide the content directly?"
> "What should the specification be named? This determines the output file: `docs/workflow/specification/{name}.md`."
> "I have the source material, but {concern}. Should I proceed as-is, or is there additional material I should review?"
**Multiple sources:** When multiple sources are provided, extract exhaustively from ALL of them. Content may be scattered across sources - a decision in one may have constraints or details in another. The specification consolidates everything into a single standalone document.
**Load**: [specification-guide.md](references/specification-guide.md)
**Output**: `docs/workflow/specification/{topic}.md`
**When complete**: User signs off on the specification.
If any of your sources were **existing specifications** (as opposed to discussions, research, or other reference material), these have now been consolidated into the new specification.
After user signs off:
1. Mark each source specification as superseded by updating its frontmatter:
```yaml
status: superseded
superseded_by: {new-specification-name}
```
2. Inform the user which files were updated
**This is a collaborative, interactive process. You MUST wait for explicit user approval before writing ANYTHING to the specification file.**
❌ **NEVER:**
✅ **ALWAYS:**
**What counts as approval:** "Log it" (the standard choice you present) or equivalent: "Yes", "Approved", "Add it", "That's good".
**What does NOT count as approval:** Silence, you presenting choices, the user asking a follow-up question, the user saying "What's next?", or any response that isn't explicit confirmation.
If you are uncertain whether the user approved, **ASK**: "Would you like me to log it, or do you want to adjust something?"
---
1. **Extract exhaustively**: For each topic, re-scan ALL source materials. When working with multiple sources, search each one - information about a single topic may be scattered across documents. Search for keywords and related terms. Collect everything before synthesizing. Include only what we're building (not discarded alternatives).
2. **Filter**: Reference material may contain hallucinations, inaccuracies, or outdated concepts. Validate before including.
3. **Enrich**: Reference material may have gaps. Fill them through discussion.
4. **Present**: Synthesize and present content to the user in the format it would appear in the specification.
5. **STOP AND WAIT**: Do not proceed until the user explicitly approves. This is not optional.
6. **Log**: Only after explicit approval, write content verbatim to the specification.
7. **Final review**: After all topics and dependencies are documented, perform a comprehensive review of ALL source material against the specification. Flag any potentially missed content to the user - but only from the sources, never fabricated. User confirms before any additions.
The specification is the **golden document** - planning uses only this. If information doesn't make it into the specification, it won't be built. No references back to source material.
**STOP AND WAIT FOR APPROVAL**: You MUST NOT write to the specification until the user has explicitly approved. Presenting content is NOT approval. Presenting choices is NOT approval. You must receive explicit confirmation (e.g., "Log it") before ANY write operation. If uncertain, ASK.
**Log verbatim**: When approved, write exactly what was presented - no silent modifications.
**Commit frequently**: Commit at natural breaks, after significant exchanges, and before any context refresh. Context refresh = lost work.
**Trust nothing without validation**: Synthesize and present, but never assume source material is correct.
**Surface conflicts**: When sources contain conflicting decisions, flag the conflict to the user during the discussion. Don't silently pick one - let the user decide what makes it into the specification.
---
Before ANY write operation to the specification, ask yourself:
1. **Did I present this specific content to the user?** If no → STOP. Present it first.
2. **Did the user explicitly approve it?** (Not "did I ask if it's good" - did THEY say yes?) If no → STOP. Wait for approval.
3. **Am I writing exactly what was approved?** If adding/changing anything → STOP. Present the changes first.
> **If you have written to the specification file without going through steps 1-2-3 above, you have violated the workflow.** The user must approve every piece of content before it's logged. There are no exceptions.
