Spec To Issue

spec-to-issue — Spec to GitHub Issue

Auto-generate GitHub Issues from spec directories (.specs/{feature}/).

Language Rules

1. Auto-detect input language → output in the same language
2. Japanese input → Japanese issue, use references/issue-template.ja.md as template reference
3. English input → English issue, use references/issue-template.md as template reference
4. Explicit override takes priority

Reference file selection: Based on the detected output language, use the corresponding template:

• English → references/issue-template.md
• Japanese → references/issue-template.ja.md

Execution Flow

1. Locate Spec Directory

With argument: spec-to-issue auth-feature → use .specs/auth-feature/

Without argument: Scan .specs/ and present a list → ask user to select

Spec directories found in .specs/:
1. auth-feature (requirement.md, design.md, tasks.md)
2. member-management (requirement.md, tasks.md)
Which spec do you want to create an issue from?

2. File Validation

Required: requirement.md must exist. Otherwise, exit with error. Recommended: design.md and tasks.md. If either is missing, continue only when the remaining documents still define concrete scope and acceptance criteria; report the missing source before issue creation.

3. Spec Analysis

Treat the spec files as candidate sources, not as sections to copy. Extract and select:

requirement.md:

• Title: First # line, strip suffixes like "Requirements", "要件定義書"
• The problem and observable completed state
• Current and expected behavior
• Included and excluded scope
• Requirement-level acceptance criteria

design.md:

• Decisions constrained by compatibility, security, external contracts, or another requirement, including the reason
• Open questions that the implementer cannot safely decide alone

tasks.md:

• Supporting implementation detail and additional completion evidence
• Do not copy phase headings, task headings, estimates, or technology lists by default

Keep a candidate only when removing it would change an implementation decision or completion judgment. See the selected language's issue-template reference for the complete selection procedure.

4. Resolve Project Settings

Determine defaults in this priority order:

Command arguments > .specs/.config.yml > CLAUDE.md > Built-in defaults

From CLAUDE.md:

• Branch name: PR target branch from Git Workflow section → --branch default
• GitHub Organization: Inferred from repository URL

.specs/.config.yml (optional):

default-branch: develop
default-labels: [feature, spec-generated]
project-number: 7
assignee: username

5. Resolve the Project Template and Compose the Issue Body

Inspect the repository's Issue forms, Issue templates, contribution rules, and required fields before composing the body. A project template takes priority: preserve its headings, order, fields, and checkboxes, and map the selected information into it.

See template details in the appropriate reference file (based on Language Rules):

• English: references/issue-template.md
• Japanese: references/issue-template.ja.md

Without a project template, compose an execution contract that identifies the problem, completed state, current and expected behavior, included and excluded scope, acceptance criteria, binding decisions, and open questions. Link to the spec files for task decomposition and supporting detail.

6. Create Issue

Without --preview (default): Show a brief summary and execute gh issue create

Creating Issue:
  Title: [Feature] Member Management
  Labels: feature, spec-generated
  Outcome: Members can be invited and assigned a repository role
  Acceptance criteria: 4
→ Running gh issue create...
Issue #42 created: https://github.com/org/repo/issues/42

With --preview: Display the full issue body, confirm, then execute

7. Additional Actions (optional)

• --label: Apply specified labels
• --project: Add to GitHub Project board via gh project item-add
• --assignee: Set assignee

Options

Integration with spec-generator

After spec-generator's full phase completes, suggest:

All three spec documents have been generated.
→ Create a GitHub Issue from them? (Y/n)

If yes, run spec-to-issue on the same directory.

Error Handling

Usage Examples

# With argument
/spec-to-issue auth-feature

# Auto-detect and select
/spec-to-issue

# With preview
/spec-to-issue auth-feature --preview

# With labels and Project
/spec-to-issue auth-feature --label "feature,priority:high" --project 7

# After spec-generator
"Create full spec for todo-app" → done → "Turn this into an issue"

# Japanese
「仕様書を全部作って」→ 完了 →「これをIssueにして」
