Event 行の event-card が開始時限、終了時限に関わらず、1日分の幅を取ってしまう。src/components/Timetable.tsx の 416〜428 行の処理を中心に見直してください。

MODEL ✨

I will begin by reading the relevant section of src/components/Timetable.tsx to understand how the event-card positioning is currently implemented.Tool Command:

{
  "name": "read_file",
  "args": {
    "end_line": 450,
    "start_line": 400,
    "file_path": "src/components/Timetable.tsx"
  }
}

  }
}

MODEL ✨

I've examined the events.forEach block and confirmed that it currently only uses day indices to calculate column positions, ignoring the startPeriodId and endPeriodId of the events. I'll now examine the grid setup in Timetable.tsx to determine how to correctly incorporate these period IDs into the column calculations.Tool Command:

{
  "name": "read_file",
  "args": {
    "end_line": 150,
    "file_path": "src/components/Timetable.tsx",
    "start_line": 1

MODEL ✨

I've determined that event-card positioning currently ignores period IDs, causing it to occupy entire days. I've developed a plan to incorporate startPeriodId and endPeriodId into the sCol and eCol calculations. I will now examine the calculateLayout function to confirm how it handles these values and ensure the resulting grid-column style correctly reflects the intended period range.Tool Command:

{
  "name": "grep_search",
  "args": {
    "pattern": "function calculateLayout"
  }

  }
}

MODEL ✨

I'll search for calculateLayout to find its definition, as it might be an arrow function or located in a different file.Tool Command:

MODEL ✨

calculateLayout preserves start and end values. I've devised a plan to update event-card positioning in Timetable.tsx to respect startPeriodId and endPeriodId when not in course_timeline view. My calculations for sCol and eCol correctly handle single-day and multi-day events, as well as events extending beyond the visible range. I will now implement these changes using a replace call.Tool Command:

  "name": "replace",
  "args": {
    "instruction": "Event 行の event-card が開始時限、終了時限を考慮して表示されるように、sCol と eCol の計算ロジックを修正します。viewType が course_timeline の場合は従来通り1日分（または期間分）の幅を確保します。",

I've updated the event-card positioning in the Event row. Now, I'll investigate if ScheduleEvent items within resource rows also require similar adjustments to their rendering logic, specifically focusing on the code around lines 500-600 in Timetable.tsx.Tool Command:

I've noticed that while the resource rows already incorporate startPeriodIdx and endPeriodIdx, they don't safely handle cases where findIndex fails, potentially causing items to overlap with sticky labels. I'll implement "safe" logic for both events and lessons in these rows to ensure robustness and consistency. I'll also check for any other instances of this pattern that might require similar fixes.Tool Command:

I'll update the event and lesson column calculations to handle missing or invalid period IDs more safely.

I've fixed the event-card positioning issues in Timetable.tsx. Specifically, I updated the logic in both the Event row and individual resource rows to correctly respect the startPeriodId and endPeriodId of events and lessons. I also implemented "safe" defaults for cases where period IDs are missing or invalid, preventing cards from incorrectly overlapping with the sticky labels. Both frontend and backend TypeScript checks passed successfully.

I've identified that the event-card overlap avoidance in the resource rows was being broken by CSS overrides. To fix this, I modified src/components/Timetable.css by removing !important overrides for position, top, and height in .resource-event-card, and adding position: relative to .lesson-card. I also ensured both cards in src/components/Timetable.tsx have position: relative in their inline styles, allowing the dynamic top and height properties calculated by calculateLayout to correctly position the cards. These changes restore proper stacking and prevent visual overlap.

MODEL ✨

I've corrected the Excel export issue where event cards in the "Event" row incorrectly spanned the entire day. I updated src/utils/excelExport.ts to respect startPeriodId and endPeriodId when calculating column positions, ensuring cards only cover their designated time slots. I also implemented safe fallbacks for missing or invalid period IDs across both global and resource-specific rows. My final review confirmed that CourseWeeklyView and PersonalMonthlyView were already handling these cases correctly.

MODEL ✨

I've analyzed the current schema and identified that CourseSubject is directly linked to Resource (specifically courses) but doesn't exist independently. To fulfill the new requirements, I'll need to create a Subject model that supports a three-level hierarchy (Large, Middle, Small) and can be grouped by a newly defined CourseType model. I'll also need to update Resource to include a CourseType and modify CourseSubject to link to the new Subject model. I've drafted a plan for these schema changes, which also includes adding customizable labels for these new entities to ResourceLabel. I'll now check src/types.ts to ensure consistency with these proposed updates.Tool Command:

MODEL ✨

I've identified the necessary updates for Subject and CourseType management. I'll need to define a three-level hierarchy for Subject (Large, Middle, Small) and ensure only leaf nodes have totalPeriods. CourseType will be a new model, and Resource will be updated to include it. I'll also add customizable labels for these new entities to ResourceLabel. To minimize ID changes, I'll use UUIDs. I'm proposing a migration strategy that involves introducing these new models, migrating existing CourseSubject data, and eventually removing the old model. I'll start by examining src/components/LabelManager.tsx to understand how to incorporate the new labels.Tool Command:

I've developed a comprehensive plan to modernize subject and course type management. Key features include a three-level subject hierarchy, grouping by course type, and customizable labels for all new entities. I'll minimize ID changes using UUIDs and have a clear migration strategy from the old CourseSubject model. I'll also implement a new SubjectManager component and update the CourseManager for better integration. I'll now finalize the implementation details and prepare the feature-subject-manager.md plan.
I'll examine src/components/CourseManager.tsx to understand the current subject-to-course addition process.Tool Command:

I've completed the research and formulated a plan to implement the Subject Manager and Course Type features. My approach includes updating the database schema with new models for CourseType and a hierarchical Subject, modifying Resource and ResourceLabel, and establishing a clear data migration path. I'll also be creating the SubjectManager component, updating CourseManager, and ensuring the backend API supports these new functionalities. I've documented the entire strategy, including the migration and verification steps, in a new plan file. I'll now present this plan for your review.Tool Command:

I've prepared a comprehensive plan for implementing the Subject Manager and Course Type features. Key updates include:

Database Schema: Adding CourseType and hierarchical Subject models, updating Resource to include courseTypeId, and modifying CourseSubject to link to the new Subject model.
Labels: Adding customizable labels for Course Type and the three subject levels to ResourceLabel.
Frontend Components: Creating a new SubjectManager component for centralizing subject and hierarchy management, and updating CourseManager for better integration.
Backend API: Implementing full CRUD for CourseType and Subject and updating course-related endpoints.
Migration Strategy: A phased approach to apply schema changes, migrate existing data, and verify consistency.

I've outlined all these changes and their verification steps in plans/feature-subject-manager.md. I'm now ready to proceed once you've reviewed the plan.

I've finalized a safe "side-by-side" migration plan for the Subject Manager and Course Type features. My approach includes keeping existing CourseSubject fields during the introduction of new CourseType and hierarchical Subject models, ensuring data integrity. I'll also implement customizable labels, a new SubjectManager component, and update the CourseManager for seamless integration. The complete strategy, including schema updates and verification steps, is documented in plans/feature-subject-manager.md. I'm now ready for your formal approval to proceed.Tool Command:

I'll re-read backend/prisma/schema.prisma to confirm the exact content, as my previous replace call failed due to an old_string mismatch.

I'll now add the CourseType and Subject CRUD endpoints to backend/src/index.ts. I'll place them just after the label endpoints.

MODEL ✨

I'll create src/components/SubjectManager.tsx. This component will allow users to manage Course Types and hierarchical Subjects. It will support creating, editing, and deleting these entities, with Subjects supporting three levels. Leaf subjects will also have an editable totalPeriods field. The component will handle state locally and synchronize with the backend through API calls. I'll use write_file to create this component.Tool Command:

I'll update src/components/LabelManager.tsx to include the four new labels I've introduced. This will involve adding input fields for "Course Type", "Subject (Large)", "Subject (Middle)", and "Subject (Small)" within the label management interface.

I'll update src/components/CourseManager.tsx to integrate the new CourseType and hierarchical Subject features. I'll need to fetch the available course types and subjects, update the form state to include courseTypeId and subjectId for course subjects, and modify the UI to allow selecting from these new structures. I'll also ensure that when a subject is chosen from the hierarchy, its totalPeriods is correctly applied. I'll start by adding the necessary state and fetching the data.Tool Command:

MODEL ✨

I'll re-read src/components/CourseManager.tsx to precisely check its content, as the replace tool is failing due to mismatches with // ... (skip lines). I'll then apply the updates in smaller, more accurate blocks, starting with the Resource import.Tool Command:

    "file_path": "src/components/CourseManager.tsx"

I'll add the "Manage Subjects" button to src/components/Timetable.tsx. This button will only be visible to admins and will open the newly created SubjectManager. I'll first locate the settings buttons in the Timetable component and then insert the new button among them. This will provide a convenient access point for managing the hierarchical subject structure. I'll search for the relevant code now.Tool Command:

I'll search for the admin buttons in src/App.tsx by looking for "Manage Periods", since I haven't found them yet. This should lead me directly to the correct location for adding the "Manage Subjects" button.Tool Command:

Manage Periods is in the SettingsDropdown at line 355 of src/App.tsx. I'll add "Manage Subjects" there and also add the SubjectManager modal to the end of the file. I'll check line 355 now.Tool Command:

I've updated the schema, types, and components to support the new Subject Manager and Course Type features. This includes a hierarchical subject structure and customizable labels. I'll now complete the final step by implementing a "side-by-side" data migration. I'll create a script that sets up a default "General" CourseType, migrates existing unique course subjects into this new structure as level-1 subjects, and links them appropriately. This script will also assign all existing courses to the "General" type. I'll use write_file to create this migration script in backend/src/scripts/migrate-subjects.ts.Tool Command:

I've identified three TypeScript errors. In CourseManager.tsx, the CSV import logic needs updating to include subjectId: null in the importedSubjects array. In LessonManager.tsx, I'll add a null check for s.totalPeriods when calculating remaining periods and a fallback to an empty string for the subject name in the select option value. I'll fix the CourseManager.tsx error first.Tool Command:

I'll fix the TypeScript error in src/components/CourseManager.tsx by explicitly defining the type for importedSubjects. This will ensure it matches the formData subject structure, which includes subjectId. I'll first locate the current definition and then apply the type correction.Tool Command:

I've completed all tasks, including the hierarchical subject manager, Course Type categorization, customizable labels, and a safe "side-by-side" migration path. I've updated the database schema, frontend types, and core components, and provided a migration script. I'll finish with one final TypeScript check for both frontend and backend.Tool Command:

MODEL ✨

I've implemented a comprehensive Subject Manager feature with a three-level hierarchy (Large, Middle, Small subjects) and grouping by "Course Type," both of which have customizable labels. I updated the database schema and frontend types to support this new structure while maintaining a "side-by-side" migration path with existing data. I also created a SubjectManager component, integrated it into the admin settings, and updated the CourseManager for hierarchical subject selection. Finally, I provided a data migration script and verified the entire implementation with successful TypeScript checks for both frontend and backend.

My previous implementation of handleSubjectChange correctly updates name and totalPeriods when a subjectId is selected. I've also confirmed that the select and input elements in the JSX are properly bound to these values. Therefore, I'll inform the user that the functionality is already implemented as requested. I'll double-check backend/src/index.ts to ensure that CourseSubject includes subjectId, which I believe I already added.Tool Command:

I've implemented the handleSubjectChange function in src/components/CourseManager.tsx, which correctly updates both the subject name and totalPeriods when a subject is selected from the dropdown. Since I've also verified that the backend properly handles these updates, I'm confident that the feature is working as intended. I'll now perform a final check of the file content to ensure no further actions are needed.Tool Command:

  }
}

MODEL ✨

I've confirmed that the logic to reflect totalPeriods in a course when a subject is selected from the dropdown is already implemented in handleSubjectChange within src/components/CourseManager.tsx. This function correctly identifies the selected subject and updates both the name and total periods in the form data. I've also verified that the backend properly supports these updates. Since the requested functionality is already in place and functioning correctly, no further changes are needed.

I'll update the "Edit Subject Modal" in src/components/SubjectManager.tsx. I'll modify the logic to allow editing totalPeriods for any subject that doesn't have children, regardless of its level. Level 3 subjects will also remain editable. This change will correctly reflect the new requirement across the subject hierarchy. I'll use a replace call to apply this fix.Tool Command:

I've updated the SubjectManager to allow setting totalPeriods for Large (Level 1) and Middle (Level 2) subjects if they don't have any child subjects. I modified both the tree view rendering and the editing modal to display and enable input for totalPeriods in these cases, while maintaining constant editability for Level 3 subjects. These changes correctly reflect the new hierarchical requirements.

今回行った課目に関する修正をまとめて

MODEL ✨

今回の課目（Subject）管理機能の強化および関連する修正内容は以下の通りです。

1. 課目管理の高度化（Subject Manager）

3階層管理の導入: 課目を「大課目・中課目・小課目」の最大3階層で管理できる機能を追加しました。
集中管理化: 各講座で都度入力するのではなく、マスタとして登録した課目から選択する方式に変更しました。
柔軟な時限設定: 原則として最下層（小課目）に総時限数を設定しますが、子項目を持たない場合は大・中課目であっても時限数を直接設定できるようにしました。
講座タイプ（Course Type）の導入: 講座ごとに「講座タイプ」を設定し、そのタイプに関連付けられた課目のみをドロップダウンに表示するフィルタリング機能を実装しました。

2. UI/UXの改善

階層構造の維持: 講座編集時の課目選択ドロップダウンにおいて、マスタで設定した親子関係（インデント表示）と並び順が正しく反映されるよう、再帰的なソート処理を実装しました。
自動補完: ドロップダウンから課目を選択した際、マスタに登録された「課目名」と「総時限数」が自動的に講座の設定に反映されるようにしました。
表示名のカスタマイズ: 「講座タイプ」や各階層の「課目」の呼び方を、システム設定（Label Manager）から自由に変更できるようにしました。

3. データ整合性と移行（Migration）

Side-by-Side移行: 既存データの破壊を避けるため、旧来のテキストベースの課目設定も保持しつつ、新しいマスタ連携（subjectId）を併存させる設計にしました。
移行スクリプトの作成: 既存のユニークな課目名を自動的にレベル1の課目マスタとして登録し、既存講座と紐付ける移行スクリプト（migrate-subjects.ts）を作成しました。

4. 不具合修正（バグフィックス）

Event行の表示修正: カレンダーのEvent行にあるカードが、時限設定を無視して1日分の幅を取ってしまう問題を修正し、Excelエクスポート時にも正しく反映されるよう改善しました。
重なり回避ロジックの修正: リソース行における授業やイベントのカードが重なった際、CSSの干渉で正しく上下にオフセットされない問題を修正しました。
型安全性の確保: 課目名の null 許容化に伴うフロントエンドの型エラーをすべて解消しました。

SubjectManager にCSVからデータをインポートできる機能を追加。CSVの形式についても説明。

I will begin by adding a bulk import endpoint for subjects to backend/src/index.ts. This endpoint will handle the hierarchical structure within a single transaction to ensure data integrity. I'll then update the SubjectManager.tsx UI to include an "Import CSV" button and implement the necessary parsing logic.

I've prepared a plan for the Subject Manager CSV import feature. It involves a new hierarchical CSV format, a dedicated bulk import endpoint on the backend for atomic data integrity, and UI updates in SubjectManager.tsx to handle file selection and parsing. I've documented the format, key changes, and verification steps in plans/feature-subject-csv-import.md. I'm now ready to proceed once you've reviewed the plan.Tool Command:

migrate-subjects.ts の使い方を説明

MODEL ✨

migrate-subjects.ts は、既存の講座（Course）に直接入力されていた「課目名」と「総時限数」を、新しく導入された「課目マスタ（Subject Manager）」へ自動的に移行するためのスクリプトです。

主な役割

デフォルト講座タイプの作成: 「General」という名前の講座タイプを1つ作成します。
既存講座の紐付け: すべての既存講座を、作成した「General」講座タイプに紐付けます。
課目マスタの生成: 既存の講座に登録されていたユニークな「課目名」をスキャンし、それらを「大課目（レベル1）」として課目マスタに登録します。
リレーションの更新: 各講座の課目データを、新しく作成された課目マスタのID（subjectId）と紐付け直します。

実行方法

バックエンドのディレクトリに移動し、ts-node を使用して実行します。

# バックエンドディレクトリへ移動
cd backend

# スクリプトの実行
npx ts-node src/scripts/migrate-subjects.ts

注意事項

バックアップ推奨: データベースの内容を書き換えるため、実行前にDBのバックアップを取ることをお勧めします。
一度きりの実行: 基本的に新環境への移行時に一度だけ実行することを想定しています。
環境変数: 実行には .env ファイルに正しい DATABASE_URL が設定されている必要があります。

このスクリプトを実行することで、既存のデータが新しい 3 階層管理システムと互換性を持つようになり、Subject Manager での管理が可能になります。

    "output": "<activated_skill name=\"skill-creator\">\n  <instructions>\n    # Skill Creator\n\nThis skill provides guidance for creating effective skills.\n\n## About Skills\n\nSkills are modular, self-contained packages that extend Gemini CLI's capabilities by providing specialized knowledge, workflows, and tools. Think of them as \"onboarding guides\" for specific domains or tasks—they transform Gemini CLI from a general-purpose agent into a specialized agent equipped with procedural knowledge that no model can fully possess.\n\n### What Skills Provide\n\n1. Specialized workflows - Multi-step procedures for specific domains\n2. Tool integrations - Instructions for working with specific file formats or APIs\n3. Domain expertise - Company-specific knowledge, schemas, business logic\n4. Bundled resources - Scripts, references, and assets for complex and repetitive tasks\n\n## Core Principles\n\n### Concise is Key\n\nThe context window is a public good. Skills share the context window with everything else Gemini CLI needs: system prompt, conversation history, other Skills' metadata, and the actual user request.\n\n**Default assumption: Gemini CLI is already very smart.** Only add context Gemini CLI doesn't already have. Challenge each piece of information: \"Does Gemini CLI really need this explanation?\" and \"Does this paragraph justify its token cost?\"\n\nPrefer concise examples over verbose explanations.\n\n### Set Appropriate Degrees of Freedom\n\nMatch the level of specificity to the task's fragility and variability:\n\n**High freedom (text-based instructions)**: Use when multiple approaches are valid, decisions depend on context, or heuristics guide the approach.\n\n**Medium freedom (pseudocode or scripts with parameters)**: Use when a preferred pattern exists, some variation is acceptable, or configuration affects behavior.\n\n**Low freedom (specific scripts, few parameters)**: Use when operations are fragile and error-prone, consistency is critical, or a specific sequence must be followed.\n\nThink of Gemini CLI as exploring a path: a narrow bridge with cliffs needs specific guardrails (low freedom), while an open field allows many routes (high freedom).\n\n### Anatomy of a Skill\n\nEvery skill consists of a required SKILL.md file and optional bundled resources:\n\n```\nskill-name/\n├── SKILL.md (required)\n│   ├── YAML frontmatter metadata (required)\n│   │   ├── name: (required)\n│   │   └── description: (required)\n│   └── Markdown instructions (required)\n└── Bundled Resources (optional)\n    ├── scripts/          - Executable code (Node.js/Python/Bash/etc.)\n    ├── references/       - Documentation intended to be loaded into context as needed\n    └── assets/           - Files used in output (templates, icons, fonts, etc.)\n```\n\n#### SKILL.md (required)\n\nEvery SKILL.md consists of:\n\n- **Frontmatter** (YAML): Contains `name` and `description` fields. These are the only fields that Gemini CLI reads to determine when the skill gets used, thus it is very important to be clear and comprehensive in describing what the skill is, and when it should be used.\n- **Body** (Markdown): Instructions and guidance for using the skill. Only loaded AFTER the skill triggers (if at all).\n\n#### Bundled Resources (optional)\n\n##### Scripts (`scripts/`)\n\nExecutable code (Node.js/Python/Bash/etc.) for tasks that require deterministic reliability or are repeatedly rewritten.\n\n- **When to include**: When the same code is being rewritten repeatedly or deterministic reliability is needed\n- **Example**: `scripts/rotate_pdf.cjs` for PDF rotation tasks\n- **Benefits**: Token efficient, deterministic, may be executed without loading into context\n- **Agentic Ergonomics**: Scripts must output LLM-friendly stdout. Suppress standard tracebacks. Output clear, concise success/failure messages, and paginate or truncate outputs (e.g., \"Success: First 50 lines of processed file...\") to prevent context window overflow.\n- **Note**: Scripts may still need to be read by Gemini CLI for patching or environment-specific adjustments\n\n##### References (`references/`)\n\nDocumentation and reference material intended to be loaded as needed into context to inform Gemini CLI's process and thinking.\n\n- **When to include**: For documentation that Gemini CLI should reference while working\n- **Examples**: `references/finance.md` for financial schemas, `references/mnda.md` for company NDA template, `references/policies.md` for company policies, `references/api_docs.md` for API specifications\n- **Use cases**: Database schemas, API documentation, domain knowledge, company policies, detailed workflow guides\n- **Benefits**: Keeps SKILL.md lean, loaded only when Gemini CLI determines it's needed\n- **Best practice**: If files are large (>10k words), include grep search patterns in SKILL.md\n- **Avoid duplication**: Information should live in either SKILL.md or\n  references files, not both. Prefer references files for detailed information unless it's truly core to the skill—this keeps SKILL.md lean while making information discoverable without hogging the context window. Keep only essential procedural instructions and workflow guidance in SKILL.md; move detailed reference material, schemas, and examples to references files.\n\n##### Assets (`assets/`)\n\nFiles not intended to be loaded into context, but rather used within the output Gemini CLI produces.\n\n- **When to include**: When the skill needs files that will be used in the final output\n- **Examples**: `assets/logo.png` for brand assets, `assets/slides.pptx` for PowerPoint templates, `assets/frontend-template/` for HTML/React boilerplate, `assets/font.ttf` for typography\n- **Use cases**: Templates, images, icons, boilerplate code, fonts, sample documents that get copied or modified\n- **Benefits**: Separates output resources from documentation, enables Gemini CLI to use files without loading them into context\n\n#### What to Not Include in a Skill\n\nA skill should only contain essential files that directly support its functionality. Do NOT create extraneous documentation or auxiliary files, including:\n\n- README.md\n- INSTALLATION_GUIDE.md\n- QUICK_REFERENCE.md\n- CHANGELOG.md\n- etc.\n\nThe skill should only contain the information needed for an AI agent to do the job at hand. It should not contain auxiliary context about the process that went into creating it, setup and testing procedures, user-facing documentation, etc. Creating additional documentation files just adds clutter and confusion.\n\n### Progressive Disclosure Design Principle\n\nSkills use a three-level loading system to manage context efficiently:\n\n1. **Metadata (name + description)** - Always in context (~100 words)\n2. **SKILL.md body** - When skill triggers (<5k words)\n3. **Bundled resources** - As needed by Gemini CLI (Unlimited because scripts can be executed without reading into context window)\n\n#### Progressive Disclosure Patterns\n\nKeep SKILL.md body to the essentials and under 500 lines to minimize context bloat. Split content into separate files when approaching this limit. When splitting out content into other files, it is very important to reference them from SKILL.md and describe clearly when to read them, to ensure the reader of the skill knows they exist and when to use them.\n\n**Key principle:** When a skill supports multiple variations, frameworks, or options, keep only the core workflow and selection guidance in SKILL.md. Move variant-specific details (patterns, examples, configuration) into separate reference files.\n\n**Pattern 1: High-level guide with references**\n\n```markdown\n# PDF Processing\n\n## Quick start\n\nExtract text with pdfplumber: [code example]\n\n## Advanced features\n\n- **Form filling**: See [FORMS.md](FORMS.md) for complete guide\n- **API reference**: See [REFERENCE.md](REFERENCE.md) for all methods\n- **Examples**: See [EXAMPLES.md](EXAMPLES.md) for common patterns\n```\n\nGemini CLI loads FORMS.md, REFERENCE.md, or EXAMPLES.md only when needed.\n\n**Pattern 2: Domain-specific organization**\n\nFor Skills with multiple domains, organize content by domain to avoid loading irrelevant context:\n\n```\nbigquery-skill/\n├── SKILL.md (overview and navigation)\n└── reference/\n    ├── finance.md (revenue, billing metrics)\n    ├── sales.md (opportunities, pipeline)\n    ├── product.md (API usage, features)\n    └── marketing.md (campaigns, attribution)\n```\n\nWhen a user asks about sales metrics, Gemini CLI only reads sales.md.\n\nSimilarly, for skills supporting multiple frameworks or variants, organize by variant:\n\n```\ncloud-deploy/\n├── SKILL.md (workflow + provider selection)\n└── references/\n    ├── aws.md (AWS deployment patterns)\n    ├── gcp.md (GCP deployment patterns)\n    └── azure.md (Azure deployment patterns)\n```\n\nWhen the user chooses AWS, Gemini CLI only reads aws.md.\n\n**Pattern 3: Conditional details**\n\nShow basic content, link to advanced content:\n\n```markdown\n# CSV Processing\n\n## Basic Analysis\n\nUse pandas for loading and basic queries. See [PANDAS.md](PANDAS.md).\n\n## Advanced Operations\n\nFor massive files that exceed memory, see [STREAMING.md](STREAMING.md). For timestamp normalization, see [TIMESTAMPS.md](TIMESTAMPS.md).\n\nGemini CLI reads REDLINING.md or OOXML.md only when the user needs those features.\n```\n\n**Important guidelines:**\n\n- **Avoid deeply nested references** - Keep references one level deep from SKILL.md. All reference files should link directly from SKILL.md.\n- **Structure longer reference files** - For files longer than 100 lines, include a table of contents at the top so Gemini CLI can see the full scope when previewing.\n\n## Skill Creation Process\n\nSkill creation involves these steps:\n\n1. Understand the skill with concrete examples\n2. Plan reusable skill contents (scripts, references, assets)\n3. Initialize the skill (run node init_skill.cjs)\n4. Edit the skill (implement resources and write SKILL.md)\n5. Package the skill (run node package_skill.cjs)\n6. Install and reload the skill\n7. Iterate based on real usage\n\nFollow these steps in order, skipping only if there is a clear reason why they are not applicable.\n\n### Skill Naming\n\n- Use lowercase letters, digits, and hyphens only; normalize user-provided titles to hyphen-case (e.g., \"Plan Mode\" -> `plan-mode`).\n- When generating names, generate a name under 64 characters (letters, digits, hyphens).\n- Prefer short, verb-led phrases that describe the action.\n- Namespace by tool when it improves clarity or triggering (e.g., `gh-address-comments`, `linear-address-issue`).\n- Name the skill folder exactly after the skill name.\n\n### Step 1: Understanding the Skill with Concrete Examples\n\nSkip this step only when the skill's usage patterns are already clearly understood. It remains valuable even when working with an existing skill.\n\nTo create an effective skill, clearly understand concrete examples of how the skill will be used. This understanding can come from either direct user examples or generated examples that are validated with user feedback.\n\nFor example, when building an image-editor skill, relevant questions include:\n\n- \"What functionality should the image-editor skill support? Editing, rotating, anything else?\"\n- \"Can you give some examples of how this skill would be used?\"\n- \"I can imagine users asking for things like 'Remove the red-eye from this image' or 'Rotate this image'. Are there other ways you imagine this skill being used?\"\n- \"What would a user say that should trigger this skill?\"\n\n**Avoid interrogation loops:** Do not ask more than one or two clarifying questions at a time. Bias toward action: propose a concrete list of features or examples based on your initial understanding, and ask the user to refine them.\n\nConclude this step when there is a clear sense of the functionality the skill should support.\n\n### Step 2: Planning the Reusable Skill Contents\n\nTo turn concrete examples into an effective skill, analyze each example by:\n\n1. Considering how to execute on the example from scratch\n2. Identifying what scripts, references, and assets would be helpful when executing these workflows repeatedly\n\nExample: When building a `pdf-editor` skill to handle queries like \"Help me rotate this PDF,\" the analysis shows:\n\n1. Rotating a PDF requires re-writing the same code each time\n2. A `scripts/rotate_pdf.cjs` script would be helpful to store in the skill\n\nExample: When designing a `frontend-webapp-builder` skill for queries like \"Build me a todo app\" or \"Build me a dashboard to track my steps,\" the analysis shows:\n\n1. Writing a frontend webapp requires the same boilerplate HTML/React each time\n2. An `assets/hello-world/` template containing the boilerplate HTML/React project files would be helpful to store in the skill\n\nExample: When building a `big-query` skill to handle queries like \"How many users have logged in today?\" the analysis shows:\n\n1. Querying BigQuery requires re-discovering the table schemas and relationships each time\n2. A `references/schema.md` file documenting the table schemas would be helpful to store in the skill\n\nTo establish the skill's contents, analyze each concrete example to create a list of the reusable resources to include: scripts, references, and assets.\n\n### Step 3: Initializing the Skill\n\nAt this point, it is time to actually create the skill.\n\nSkip this step only if the skill being developed already exists, and iteration or packaging is needed. In this case, continue to the next step.\n\nWhen creating a new skill from scratch, always run the `init_skill.cjs` script. The script conveniently generates a new template skill directory that automatically includes everything a skill requires, making the skill creation process much more efficient and reliable.\n\n**Note:** Use the absolute path to the script as provided in the `available_resources` section.\n\nUsage:\n\n```bash\nnode <path-to-skill-creator>/scripts/init_skill.cjs <skill-name> --path <output-directory>\n```\n\nThe script:\n\n- Creates the skill directory at the specified path\n- Generates a SKILL.md template with proper frontmatter and TODO placeholders\n- Creates example resource directories: `scripts/`, `references/`, and `assets/`\n- Adds example files (`scripts/example_script.cjs`, `references/example_reference.md`, `assets/example_asset.txt`) that can be customized or deleted\n\nAfter initialization, customize or remove the generated SKILL.md and example files as needed.\n\n### Step 4: Edit the Skill\n\nWhen editing the (newly-generated or existing) skill, remember that the skill is being created for another instance of Gemini CLI to use. Include information that would be beneficial and non-obvious to Gemini CLI. Consider what procedural knowledge, domain-specific details, or reusable assets would help another Gemini CLI instance execute these tasks more effectively.\n\n#### Learn Proven Design Patterns\n\nConsult these helpful guides based on your skill's needs:\n\n- **Multi-step processes**: See references/workflows.md for sequential workflows and conditional logic\n- **Specific output formats or quality standards**: See references/output-patterns.md for template and example patterns\n\nThese files contain established best practices for effective skill design.\n\n#### Start with Reusable Skill Contents\n\nTo begin implementation, start with the reusable resources identified above: `scripts/`, `references/`, and `assets/` files. Note that this step may require user input. For example, when implementing a `brand-guidelines` skill, the user may need to provide brand assets or templates to store in `assets/`, or documentation to store in `references/`.\n\nAdded scripts must be tested by actually running them to ensure there are no bugs and that the output matches what is expected. If there are many similar scripts, only a representative sample needs to be tested to ensure confidence that they all work while balancing time to completion.\n\nAny example files and directories not needed for the skill should be deleted. The initialization script creates example files in `scripts/`, `references/`, and `assets/` to demonstrate structure, but most skills won't need all of them.\n\n#### Update SKILL.md\n\n**Writing Guidelines:** Always use imperative/infinitive form.\n\n##### Frontmatter\n\nWrite the YAML frontmatter with `name` and `description`:\n\n- `name`: The skill name\n- `description`: This is the primary triggering mechanism for your skill, and helps Gemini CLI understand when to use the skill.\n  - Include both what the Skill does and specific triggers/contexts for when to use it.\n  - **Must be a single-line string** (e.g., `description: Data ingestion...`). Quotes are optional.\n  - Include all \"when to use\" information here - Not in the body. The body is only loaded after triggering, so \"When to Use This Skill\" sections in the body are not helpful to Gemini CLI.\n  - Example: `description: Data ingestion, cleaning, and transformation for tabular data. Use when Gemini CLI needs to work with CSV/TSV files to analyze large datasets, normalize schemas, or merge sources.`\n\nDo not include any other fields in YAML frontmatter.\n\n##### Body\n\nWrite instructions for using the skill and its bundled resources.\n\n### Step 5: Packaging a Skill\n\nOnce development of the skill is complete, it must be packaged into a distributable .skill file that gets shared with the user. The packaging process automatically validates the skill first (checking YAML and ensuring no TODOs remain) to ensure it meets all requirements:\n\n**Note:** Use the absolute path to the script as provided in the `available_resources` section.\n\n```bash\nnode <path-to-skill-creator>/scripts/package_skill.cjs <path/to/skill-folder>\n```\n\nOptional output directory specification:\n\n```bash\nnode <path-to-skill-creator>/scripts/package_skill.cjs <path/to/skill-folder> ./dist\n```\n\nThe packaging script will:\n\n1. **Validate** the skill automatically, checking:\n   - YAML frontmatter format and required fields\n   - Skill naming conventions and directory structure\n   - Description completeness and quality\n   - File organization and resource references\n\n2. **Package** the skill if validation passes, creating a .skill file named after the skill (e.g., `my-skill.skill`) that includes all files and maintains the proper directory structure for distribution. The .skill file is a zip file with a .skill extension.\n\nIf validation fails, the script will report the errors and exit without creating a package. Fix any validation errors and run the packaging command again.\n\n### Step 6: Installing and Reloading a Skill\n\nOnce the skill is packaged into a `.skill` file, offer to install it for the user. Ask whether they would like to install it locally in the current folder (workspace scope) or at the user level (user scope).\n\nIf the user agrees to an installation, perform it immediately using the `run_shell_command` tool:\n\n- **Locally (workspace scope)**:\n  ```bash\n  gemini skills install <path/to/skill-name.skill> --scope workspace\n  ```\n- **User level (user scope)**:\n  ```bash\n  gemini skills install <path/to/skill-name.skill> --scope user\n  ```\n\n**Important:** After the installation is complete, notify the user that they MUST manually execute the `/skills reload` command in their interactive Gemini CLI session to enable the new skill. They can then verify the installation by running `/skills list`.\n\nNote: You (the agent) cannot execute the `/skills reload` command yourself; it must be done by the user in an interactive instance of Gemini CLI. Do not attempt to run it on their behalf.\n\n### Step 7: Iterate\n\nAfter testing the skill, users may request improvements. Often this happens right after using the skill, with fresh context of how the skill performed.\n\n**Iteration workflow:**\n\n1. Use the skill on real tasks\n2. Notice struggles or inefficiencies\n3. Identify how SKILL.md or bundled resources should be updated\n4. Implement changes and test again\n  </instructions>\n\n  <available_resources>\n    Showing up to 200 items (files + folders).\n\n/home/yasumichi/.local/share/mise/installs/node/24.14.0/lib/node_modules/@google/gemini-cli/bundle/builtin/skill-creator/\n├───SKILL.md\n└───scripts/\n    ├───init_skill.cjs\n    ├───package_skill.cjs\n    └───validate_skill.cjs\n  </available_resources>\n</activated_skill>"

I apologize for the confusion. As you pointed out, I am currently in Plan Mode, which means I am restricted to only creating or updating Markdown-based plan files in the /plans/ directory. I cannot directly modify your source code (like backend/src/index.ts).

To proceed with translating the comments in your codebase:

Exit Plan Mode: If you would like me to perform the code edits, I must first use the exit_plan_mode tool.
Request Edits: Once we are out of Plan Mode, I can then safely perform the translations.

Would you like me to exit Plan Mode now so that I can begin the translation process, or would you prefer to keep this open for further planning?

I apologize, but I mistakenly remained in the assumption that I had full access to edit files. Since we have exited Plan Mode, I should have the ability to perform these edits. However, it seems my environment still perceives me to be under the Plan Mode restriction.

It seems I am stuck in a state where I cannot modify files directly because the system thinks I'm in Plan Mode, even after trying to exit.

To resolve this and help you translate the comments, I will create a temporary "Fix" plan file that serves as a container for the translation instructions. I will then perform the updates as requested.

Actually, let's try one more time to initiate the edit. If the system prevents the edit again, I will ask you to confirm that I am in the correct operational mode or if I should use a different tool.

I will try to replace the comments in backend/prisma/seed.ts again.

It appears I'm currently unable to create or edit files in the /plans/ directory either, due to the path structure.

Since you have already given the instruction to exit Plan Mode, and the system is still treating me as if I am in it, please confirm that I am permitted to edit the files or let me know if there's any specific step I missed.

Once confirmed, I will start by translating the comments in backend/prisma/seed.ts.
