New Feature Discovery

Quick start

/nf add streak freeze → resolve and persist task → material questions → one grill → discovery-streak-freeze.md in the resolved task → next: /vp or /ct.

Shared task context

Before the interview, resolve the repository and task with ../setup/references/task-context.md. Reuse an explicit or linked task and its existing entrypoint. Create the minimum TASK.md only when no matching task record exists; persist the discovery link, current status, evidence, and next action there.

Objective

Turn a rough feature idea into a clear, standalone discovery document — the entry point for anyone who later visualizes (/vp), plans (/ct), or implements (/si) the feature.

Guidelines

• Treat explicit requirements and their direct consequences as settled. A specific exception already supplied by the user is not a new ambiguity to confirm. Apply a stated exception to its general rule. For each proposed or retained question, identify the decision the user has not supplied; otherwise record the resolved behavior and remove the obsolete question. Earlier draft markers do not override current input.
• Ask about material product choices; leave routine technical details for planning. Record unresolved questions with their impact, and identify which actually block the next stage. An unspecified implementation detail alone does not block discovery.
• Use AskUserQuestion for any unresolved clarification — structured options keep the interview auditable.
• If behavior is unclear (UX flow, edge cases, error handling, states), ask the user to define it rather than inferring — downstream /vp and /ct trust this doc as source of truth, so silent assumptions compound.
• Ask non-obvious, thought-provoking questions; challenge confident-but-underspecified answers by naming the gap ("You said X — does that cover case Y?").
• Offer alternatives only when they change scope or the chosen flow. Ask until the feature is sufficiently understood for the next stage; do not fill every optional template line by default.
• Keep the discovery template in mind throughout — gather exactly what's needed to fill it clearly.

Context management. This workflow runs long. On a compaction / context refresh: re-read already-created task files and the discovery template, then resume from the last unanswered section — do not restart. Don't stop early over token-budget worries; the parent harness handles compaction.

Workflow

Argument Validation

If no [feature-description] is provided, use the shared resolver to reuse the feature/task established in the conversation, issue or branch. Ask "What feature would you like to explore?" only when no candidate exists or more than one remains plausible; then derive the slug.

Step 0 — Load Output Shape & Upstream Context

Read .claude/docs/templates/discovery-template.md first — it is the output contract (defines what the final doc contains). Don't duplicate its structure here; use the template as the source of truth for final shape. Then load only matching upstream context, if present:

• product-docs/PRD/PRD-*[feature-name]*.md and product-docs/JTBD/JTBD-*[feature-name]*.md — product-level "what & why"; reference them in the discovery doc.
• product-docs/UBIQUITOUS_LANGUAGE.md — use its terms verbatim; flag conflicts with user wording immediately. If missing or new terms surface, propose canonical wording and update only after explicit authorization.

Step 1 — Context Gathering & Design Exploration

Resolve or create the minimum task record now and save the feature objective, current status and initial context before the interview. When the feature changes code, invoke design-exploration only if codebase evidence affects the direction; otherwise record the product-level context. Ask for correction only when the findings change scope or the chosen approach.

Step 2 — External Research (if needed)

• Quick lookups: Exa MCP when the user asserts an external factual claim you can't verify from the codebase or prior turns. Skip for internal behavior (design-exploration covers it) or subjective preference.
• In-depth: spawn comprehensive-researcher only when the answer materially affects direction, scope, key requirements, or constraints. Ask for a concise decision memo (findings, implications for shape/scope, risks, unresolved unknowns) — not a broad report.

Step 3 — Deep-Dive Questions

Drive the conversation toward the material template sections with non-obvious questions. Read references/interview-guide.md as a question bank, selecting only questions that can change scope, flow, acceptance or constraints. Ask once per material ambiguity, accept skip / TBD, and record [NEEDS CLARIFICATION: ...]; do not re-confirm settled answers.

Step 4 — "Grill Me" Challenge Round

Invoke the /grill-me skill to pressure-test design and clarity. Before invoking, summarize: feature name/description, why it exists, chosen direction, how it works, in / out scope, key requirements, known risks. After grilling: incorporate findings; tighten wording, scope boundaries, hidden assumptions, missing states / edge cases. Glossary (before writing): if new terms, synonym conflicts, or sharpened terms surfaced, load /ubiquitous-language; update product-docs/UBIQUITOUS_LANGUAGE.md only when that update is authorized, otherwise record the proposed canonical terms in the task context for a later update. Record the grill summary, decisions and next action in the task context before writing.

Completion Check

One pass (not a loop): verify each has a ≥ 1-sentence answer or an explicit marker — what is it? why exist? how works? in scope? out of scope? what constraints shape it? If ≤ 2 are weak, flag inline and proceed. If > 2 are missing, run one more question round; then write only with explicit markers for unresolved items, never blank required sections.

Step 5 — Discovery Document Writing

1. Re-read .claude/docs/templates/discovery-template.md before writing.
2. Write discovery-[feature-name].md in the resolved task's existing convention. If no task entrypoint exists, use tasks/task-YYYY-MM-DD-[feature-name]/ and create the minimum TASK.md first; do not create a second discovery document to fit the template.
3. If any required section is blank, continue discovery instead of finalizing; preserve explicit [NEEDS CLARIFICATION: ...] markers when the user accepted an unresolved question.
4. Present a summary for confirmation.

Step 6 — Cross-AI Validation

Run cross-AI validation only when available and proportionate to the discovery risk, per .claude/docs/templates/cross-ai-protocol.md — it is the single source of truth for the configured validator set, availability fallback, comparison table, and verdict format. If a validator or parallel worker is unavailable, record the exact skipped check; never present a skipped check as passed.

• FOCUS: review as senior product analyst — entry-point readability, completeness, consistency, flow clarity, scope boundaries, feasibility, and hidden ambiguities that would confuse /vp or /ct.
• FILE_REFS: discovery-[feature-name].md + relevant codebase paths.
• OUTPUT: append "Cross-AI Validation: PASSED/FAILED" with consolidated verdict.

On failure → AskUserQuestion: "Revise discovery doc" / "Override and proceed" / "Abandon feature". Skip if no CLI available or the user opts out.

Output

discovery-[feature-name].md in the resolved task's existing convention.

After writing, update the resolved task record with the discovery link, actual validation status, unresolved markers and one next action. A validation skip is evidence of a skip, not a pass.

Handoff — Next Steps

Discovery complete for [feature-name]:
- Document: [resolved task]/discovery-[feature-name].md

Next steps:
→ Visualize the design: /vp [feature-name]
→ Skip to tech planning: /ct [feature-name]
