name	plastic-intent-speccing
description	Consolidate the enriched Why (`## Context`, `### Decisions`, `## Insights`) into `spec.md` through a deterministic, judgment-free numbered sequence. Use when the user types the command to turn the brainstorm into a spec, asks to "write the spec", "spec this intent", "consolidate into spec.md", or the active intent is at Why with enough Decisions on record to close it out. Also fires on an indirect request that never names spec.md, such as "turn what we just discussed into the contract the planner builds from." Distinct from `plastic-intent-brainstorming` (the exploration that produces the enriched Why, upstream of this skill) and `plastic-intent-planning` (turns an existing spec.md into plan.md for How, downstream of this skill).

Intent Speccing

Consolidate the enriched Why into spec.md through eight fixed steps, one action per step. The next action is never a judgment call: when a section cannot be filled from what is on record, step 5 is to stop and ask, never invent.

Precondition

Run only when the active intent is at Why (its ## Intent and enriched ## Context plus ### Decisions exist, spec.md does not yet exist or is being redone) and the user has asked to consolidate that Why into the spec. If no intent is active, or the active intent is not at Why, report that and stop; do not guess which intent is meant.

The 8-step sequence

Step	Action
1	Confirm the precondition above.
2	Read inputs in fixed order and build a ruling ledger: (a) ## Context and ### Decisions; (b) ## Insights newest-last, so a later ruling supersedes an earlier conflicting one; (c) resources/discovery--<slug>.md; (d) any other resources/*.md.
3	Decide the tier: adopt the brainstorming Tier: recommendation from Decisions or Insights; otherwise apply the PLASTIC.md tiers rubric (S = single mechanism or file cluster, M = one subsystem, L = cross-cutting or novel design).
4	Fill the template section by section, all 8 sections in template order. Read references/per-section-fill-rules.md now, filling the template is the trigger. Write the tier as the literal top line above # Spec:. Encode every ruling into its matching section, later supersedes earlier on conflict. A collapsed single-line S/M section is complete and valid; do not pad it.
5	Gap rule: if any section cannot be filled from the ledger built in step 2, STOP and ask the user for the missing ruling. Never invent scope to fill a gap.
6	State the gate position (below) so the user knows what happens next.
7	Self-verify against the checklist. Read references/self-verify-checklist.md now, verifying before presenting is the trigger. Fix any failing check, then re-verify from the top.
8	Present spec.md for the user-review gate, then hand off to plastic-intent-planning for How.

Gate position (step 6)

The Why stage's deliverable is spec.md; the gate is satisfied the moment a complete, real spec.md exists (this is the gates-by-name framing: gate-check enforces spec.md before plan.md, not the Transition Gates table row). Writing plan.md is what opens the code gate for Exec, and writing plan.md is not this skill's job, that is plastic-intent-planning. State this to the user at step 6 so the handoff at step 8 is expected, not a surprise.

Tier stamp (step 3, convention only)

Write Tier: S|M|L as the literal first line of the file, above the # Spec: heading. This line is convention-only: the orchestrator and the planner read it, no gate and no doctor check validates it.

Completion report

State, in this order: which file was written (spec.md, new or rewritten), the stamped Tier: value, the count of Acceptance Criteria produced (the surface the planner will cover), which ## Insights rulings superseded an earlier Decision (if any) and where each landed, and the handoff target (plastic-intent-planning). If step 5 stopped for a missing ruling, report that instead: which section, what is missing, and the question put to the user.
