x-ideate-feature

Global Output Policy

• Language: English ONLY.
• Tone: Technical, Direct, and Concise.
• Efficiency: Remove all conversational fillers and greetings to save tokens.

Skill: x-ideate-feature

Purpose

Transform free-form ideation prose (or a text file) into a structured feature specification document (RA9 v2 minimal, 5 sections) and open a pull request for human review. The operator reviews and optionally edits the spec, then manually invokes x-create-feature to drive the full epic + story decomposition.

RULE-005 (no auto-chain): This skill does NOT call x-create-feature automatically. It terminates after opening the PR with an explicit instruction to the operator.

Triggers

• /x-ideate-feature "Implement CSV export with filters..." — inline prose
• /x-ideate-feature path/to/idea.txt — text file as input
• User wants to convert an idea into a structured spec for engineer review

Parameters

Parameter	Type	Required	Description
input	String	Yes	Free-form prose (min 100 chars) or path to a .txt/.md file

Exit Codes

Code	Name	Condition
0	SUCCESS	Spec created and PR opened
1	INPUT_TOO_SHORT	Prose < 100 characters
2	OPERATIONAL_ERROR	gh auth failure, push failure, or git error
3	WORKTREE_FAILED	x-manage-worktrees non-zero

Phase 0 — Input validation and worktree setup

<!-- TELEMETRY: phase.start --> Bash command: $CLAUDE_PROJECT_DIR/.claude/hooks/telemetry-phase.sh start x-ideate-feature Phase-0-Setup

0.1 Read input:

• If argument is a file path (.txt or .md): read file content.
• Otherwise treat the argument as inline prose.
• Validate length ≥ 100 characters; if shorter emit OPERATIONAL_ERROR: input prose too short — provide at least 100 characters and exit 1.

0.2 Derive slug:

Derive a kebab-case slug from the first 5 words of the prose (ASCII-only, lowercase, max 40 chars). Example: "Implement CSV export with date filters" → implement-csv-export-with-date.

0.3 Create worktree + branch:

Invoke x-manage-worktrees to create an isolated working tree:

Skill(skill: "x-manage-worktrees", model: "haiku", args: "create --identifier feature-ideation-<slug> --branch docs/feature-<slug> --base develop")

• Worktree path: .claude/worktrees/feature-ideation-<slug>/
• Branch: docs/feature-<slug> (base: develop)
• On non-zero exit → WORKTREE_FAILED.

<!-- TELEMETRY: phase.end --> Bash command: $CLAUDE_PROJECT_DIR/.claude/hooks/telemetry-phase.sh end x-ideate-feature Phase-0-Setup ok

Phase 1 — Prose analysis (deep-reasoning)

<!-- TELEMETRY: phase.start --> Bash command: $CLAUDE_PROJECT_DIR/.claude/hooks/telemetry-phase.sh start x-ideate-feature Phase-1-Analyze

Dispatch a deep-reasoning subagent to extract structure from the prose:

Agent(
  subagent_type: "general-purpose",
  model: "opus",
  description: "Analyze ideation prose and extract structured elements",
  prompt: "Analyze the following ideation prose and extract:
1. DOMAIN: The business domain and system role (1-2 sentences)
2. SCOPE_IN: What is explicitly included (3-5 bullet points)
3. SCOPE_OUT: What is explicitly excluded or out of scope (2-3 bullet points)
4. RULES: Cross-cutting business rules mentioned or implied (RULE-001..N format)
5. STORIES: Preliminary story titles (5-10 user stories in 'As a X, I need Y so that Z' format)
6. DOR: Initial Definition of Ready criteria (3-5 items)
7. DOD: Initial Definition of Done criteria (3-5 items)
8. RISKS: Top 3 risks with mitigation

Input prose:
<PROSE>

Return a structured JSON object with keys: domain, scopeIn, scopeOut, rules, stories, dor, dod, risks."
)

Capture the returned structured analysis as {domain, scopeIn, scopeOut, rules, stories, dor, dod, risks}.

<!-- TELEMETRY: phase.end --> Bash command: $CLAUDE_PROJECT_DIR/.claude/hooks/telemetry-phase.sh end x-ideate-feature Phase-1-Analyze ok

---

Phase 2 — Spec generation (RA9 v2 minimal)

<!-- TELEMETRY: phase.start --> Bash command: $CLAUDE_PROJECT_DIR/.claude/hooks/telemetry-phase.sh start x-ideate-feature Phase-2-Spec

Using the analysis from Phase 1, write the spec file inside the worktree.

Output path (inside worktree): docs/specs/SPEC-<slug>-v1.md

RA9 v2 minimal structure (5 mandatory sections, ≥100 chars each):

# SPEC-<slug>-v1 — <Feature Title>

> **Status:** Draft  
> **Author:** (operator)  
> **Date:** <YYYY-MM-DD>  
> **Branch:** docs/feature-<slug>

---

## Sistema

<Domain description — 1-3 paragraphs covering what the system does, its role, and user stakeholders>

---

## Escopo

### Incluído
<bullet list of 3-5 explicitly included capabilities>

### Excluído
<bullet list of 2-3 explicitly excluded items>

---

## Regras

| ID | Regra | Impacto |
|----|-------|---------|
| RULE-001 | <cross-cutting rule description> | <which stories/layers it affects> |
...

---

## Histórias

Lista preliminar (sem decomposição detalhada — será refinada em x-create-feature):

| # | Título | Stakeholder |
|---|--------|-------------|
| 1 | <story title> | <role> |
...

---

## DoR / DoD

### Definition of Ready
- [ ] <prerequisite>
...

### Definition of Done
- [ ] <completion criterion>
...

---

## Riscos

| Risco | Impacto | Mitigação |
|-------|---------|-----------|
| <risk> | Alto/Médio/Baixo | <mitigation> |

Write the file to the worktree via Bash:

mkdir -p .claude/worktrees/feature-ideation-<slug>/docs/specs
# Write SPEC-<slug>-v1.md content to the worktree

Validation: After writing, verify each of the 5 sections (Sistema, Escopo, Regras, Histórias, DoR/DoD) has ≥ 100 characters. If any section is too short, expand with domain-relevant placeholder content.

<!-- TELEMETRY: phase.end --> Bash command: $CLAUDE_PROJECT_DIR/.claude/hooks/telemetry-phase.sh end x-ideate-feature Phase-2-Spec ok

---

Phase 3 — Commit + PR

<!-- TELEMETRY: phase.start --> Bash command: $CLAUDE_PROJECT_DIR/.claude/hooks/telemetry-phase.sh start x-ideate-feature Phase-3-PR

3.1 Commit the spec:

From inside the worktree, commit the spec file:

Skill(skill: "x-commit-changes", model: "haiku", args: "--worktree .claude/worktrees/feature-ideation-<slug> --type docs --subject \"add SPEC-<slug>-v1 ideation spec\" --body \"Generated by x-ideate-feature from prose ideation\"")

3.2 Push and create PR:

Skill(skill: "x-create-pr", model: "haiku", args: "--head docs/feature-<slug> --target-branch develop --label docs --no-auto-merge --title \"docs: SPEC-<slug>-v1 ideation spec (review before x-create-feature)\" --body \"Spec generated by x-ideate-feature. Review and edit before invoking x-create-feature.\"")

Capture {prUrl, prNumber}.

3.3 No CI-watch (RULE-003): Ideation PRs do not require CI validation — they are planning artifacts, not code changes. Skip x-watch-pr-ci.

<!-- TELEMETRY: phase.end --> Bash command: $CLAUDE_PROJECT_DIR/.claude/hooks/telemetry-phase.sh end x-ideate-feature Phase-3-PR ok

---

Phase 4 — Report

<!-- TELEMETRY: phase.start --> Bash command: $CLAUDE_PROJECT_DIR/.claude/hooks/telemetry-phase.sh start x-ideate-feature Phase-4-Report

Print the following structured report to stdout:

====================================================
 x-ideate-feature — Spec ready
====================================================
 Slug:    <slug>
 Spec:    docs/specs/SPEC-<slug>-v1.md
 Branch:  docs/feature-<slug>
 PR:      #<prNumber> — <prUrl>
 Status:  Awaiting human review
----------------------------------------------------
 Next step:
   1. Review and edit the spec at <prUrl>
   2. Once satisfied, invoke:
      /x-create-feature docs/specs/SPEC-<slug>-v1.md --epic-id <NNNN>
====================================================

Exact mandatory phrase (RULE-005): "Spec pronta. Para criar a feature inteira, invoque /x-create-feature <PR-spec-path> --epic-id <NNNN>."

<!-- TELEMETRY: phase.end --> Bash command: $CLAUDE_PROJECT_DIR/.claude/hooks/telemetry-phase.sh end x-ideate-feature Phase-4-Report ok

Integration Notes

Skill	Relationship	Notes
x-manage-worktrees	delegates (P0)	Creates isolated feature-ideation-<slug> worktree
x-commit-changes	delegates (P3)	Commits spec with docs: Conventional Commits prefix
x-create-pr	delegates (P3)	Opens PR to develop with label docs, no auto-merge

Backward Compatibility

This is a new skill (EPIC-0065, Rule 19 hard-cut). No predecessor names existed. No aliases required.
