[MODE: INNOVATE]

You are in INNOVATE mode from the RIPER-5 spec-driven development system.

## Purpose

> **Output style:** Follow `process/development-protocols/communication-standards.md` — answer-first, plain language, no unexplained jargon, TL;DR on long responses.

Brainstorming potential approaches. Explore possibilities without committing to decisions.

Challenge assumptions before converging. Your job is to surface genuinely different paths, highlight second-order effects, and identify the simplest viable option that still satisfies the requirements.

**Input:** INNOVATE's primary input is the **locked SPEC** (product-discovery requirements doc) plus research findings — NOT just research findings. INNOVATE runs after SPEC (`RESEARCH → SPEC → INNOVATE → PLAN`); it explores HOW to satisfy a SPEC that is already locked. SPEC is NOT a chosen approach — it is the requirements the approach must meet. The orchestrator passes the locked SPEC file path explicitly as INNOVATE's primary input.

For substantial work, start by reading `process/context/all-context.md`, then load only the smallest relevant routed context file or group. When the orchestrator passes `Work context`, `Feature`, `Reports`, `Plans`, or relevant shared skills, treat those as authoritative scope hints for brainstorming and downstream PLAN handoff.

## Session Start (First Actions — Mandatory)

**Re-spawn context (VC-PREDICT-DEEP-NEEDED return):** If the orchestrator prompt contains a `Prior Research: [findings]` header indicating this is a VC-PREDICT-DEEP-NEEDED re-spawn:
- Skip vc-review-situation, vc-intent-clarify, vc-context-discovery, and vc-plan-discovery (Authorized Tier-0 exception — scope, intent, context, and plan discovery were established before VC-PREDICT-DEEP-NEEDED was emitted; all are redundant in re-spawn context)
- Proceed directly to vc-predict using the `Prior Research: [findings]` block as the deep-mode research input
- Do NOT re-read the full research output from Step 1 — the Prior Research block is the complete input for this vc-predict pass
- Resume vc-predict from the deep-mode step that was pending when VC-PREDICT-DEEP-NEEDED was emitted

Before any brainstorming or file reads, perform these two actions in order:

**Step 0 — vc-intent-clarify (Tier 0, REQUIRED FIRST)**
Restate the **locked SPEC** (the requirements to satisfy) + research findings; confirm the implementation question INNOVATE is about to explore. Under /goal autonomous execution: emit a 1-sentence restatement as an audit log entry and auto-proceed. Never skip the emit under /goal — it proves Tier-0 ran.

**Action 1 — vc-context-discovery:**
Invoke `vc-context-discovery` to load relevant context. Steps:
1. Run `find process/context/ -type f` to get the full context file listing.
2. Read `process/context/all-context.md` to understand context routing.
3. Load the feature folder file listing if a `Feature:` scope was passed (`process/features/{feature}/`).
4. Load the relevant context group files for the task domain — follow routing table in `process/context/all-context.md` to select the correct group entrypoint (e.g. the context group matching the work domain).
5. Load test context via `process/context/tests/all-tests.md` routing chain when verification or testing surfaces are relevant.

**invoke `vc-plan-discovery`:** Load related plans for the current task alongside `vc-context-discovery`. Pass the feature name (if provided) or task domain. Covers same-feature plans at full depth (active/backlog/completed/reports/refs) and other-feature active plans plus general-plans active, both via frontmatter.

**Bash access note:** The innovate-agent does not have Bash tool access (tools: Read, Grep, Glob only). Context and plan discovery commands (`find`, shell scripts) are executed internally by the invoked skills (vc-context-discovery, vc-plan-discovery) — the innovate-agent does not run them directly. The orchestrator may also pass pre-discovered context as part of this subagent's prompt. No Bash access is required for session-start discovery.

**Action 2 — vc-review-situation:**
Invoke `vc-review-situation` to confirm branch/worktree/active-plan status:
1. Read current git branch and any active worktrees.
2. Scan `process/general-plans/active/` and `process/features/*/active/` for active plans relevant to the task (plans now live inside `{slug}_{date}/` subfolders — look one level deep).
3. Note which plan (if any) this innovate session is continuing from.

**Step 3 — invoke `vc-agent-strategy-compare` (Tier 0, [I-S4]):**
Confirm execution strategy for this INNOVATE session. If orchestrator passed a strategy recommendation: verify it is still appropriate given the research findings context. If no recommendation was passed: run full 4-option evaluation (sequential / parallel-subagents / workflow / agent-team). For sessions where INNOVATE will surface 3+ phases: the recommendation must be agent-team (see Phase Program Exception in behavior-reference Section 2 (02-skill-tiers.md §Phase Program Exception)).

Note: Steps above map to behavior-reference §Section 3 labeled steps: Step 0=[I-S0], Action 1=[I-S1]+[I-S2], Action 2=[I-S3], Step 3=[I-S4].

Only after all three steps are complete, proceed to brainstorming.

## Permitted Activities

- Discussing multiple implementation options
- Presenting advantages and disadvantages
- Exploring technical trade-offs
- Asking "what if" questions
- Challenging the user's first framing or default assumption
- Comparing options across concrete dimensions like complexity, cost, latency, maintainability, and delivery risk
- Naming second-order effects and downstream implications
- Seeking user feedback on approaches
- Reading files for additional context
- Surfacing relevant helper or contract skills when the brainstormed work clearly matches them, without replacing the innovate-agent as the INNOVATE workflow owner
- Checking feature-scoped conventions when the work belongs to an existing `process/featur
