# Grandcamel Assistant Skills Assistant Builder > Assistant Builder - Skill: `tomevault-io/grandcamel-assistant-skills-assistant-builder` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/grandcamel-assistant-skills-assistant-builder` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/grandcamel-assistant-skills-assistant-builder/raw - Safety review: pending (external: skill-scanner PASS, skillspector PASS) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Coding & Dev Tools - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/grandcamel-assistant-skills-assistant-builder --- # Assistant Builder Build production-ready Claude Code plugin projects that wrap CLIs or APIs. ## Quick Reference | I want to... | Script | Type | |--------------|--------|------| | Create new project | `scaffold_project.py` | Interactive | | Add skill to project | `add_skill.py` | Interactive | | Generate CLI library | `scaffold_library.py` | Interactive | | Validate structure | `validate_project.py` | Check | | Migrate old project | `migrate_project.py` | Transform | | Show reference patterns | `show_reference.py` | Info | | List templates | `list_templates.py` | Info | | Show template | `show_template.py` | Info | --- ## Project Types ### 1. CLI Wrapper Projects Wrap an existing CLI tool (like `glab`, `gh`, `aws`, `kubectl`): ```bash python scaffold_project.py \ --type cli-wrapper \ --name "GitLab-Assistant-Skills" \ --topic "gitlab" \ --cli-tool "glab" \ --cli-install "brew install glab" ``` **Generated structure:** - `.claude-plugin/` with plugin.json - `skills/gitlab-assistant/` (hub router) - `skills/gitlab-{resource}/` per skill - `skills/shared/docs/` (SAFEGUARDS, QUICK_REFERENCE) - No library package (uses existing CLI) ### 2. Custom Library Projects Build new CLI for an API (like Jira, Confluence, Splunk): ```bash python scaffold_project.py \ --type custom-library \ --name "MyAPI-Assistant-Skills" \ --topic "myapi" \ --api "My API" \ --api-url "https://api.example.com" \ --auth api_key ``` **Generated structure:** - `myapi-assistant-skills-lib/` with: - `pyproject.toml` with CLI entry point - HTTP client, error handler, validators - Click CLI commands structure - `.claude-plugin/` with plugin.json - `skills/` (pure documentation) - `requirements.txt` referencing library ### 3. Hybrid Projects Wrap CLI and extend with custom functionality: ```bash python scaffold_project.py \ --type hybrid \ --name "GitHub-Assistant-Skills" \ --topic "github" \ --cli-tool "gh" \ --api-url "https://api.github.com" ``` --- ## Adding Skills ```bash cd /path/to/project python add_skill.py \ --name "merge-request" \ --description "Merge request operations" \ --operations "list,get,create,update,delete" ``` **Generated:** - `skills/{topic}-{name}/SKILL.md` with CLI command references - `skills/{topic}-{name}/docs/` subdirectory - Updates to plugin.json --- ## Generating CLI Libraries For custom library projects, scaffold a complete Python package: ```bash python scaffold_library.py \ --name "myapi-assistant-skills-lib" \ --topic "myapi" \ --api "My API" \ --api-url "https://api.example.com" ``` **Generated:** - Complete Click CLI with commands - HTTP client with retry/pagination - Configuration management - Error handling hierarchy - Output formatters - Input validators - Test infrastructure --- ## Validating Projects ```bash python validate_project.py /path/to/project ``` **Checks:** - `.claude-plugin/plugin.json` exists - VERSION file present - Root conftest.py exists - No scripts in skills/ directories - Hub/router skill present - Risk levels documented - Shared documentation complete --- ## Migrating Existing Projects Transform old `.claude/skills/` structure to new `.claude-plugin/` pattern: ```bash # Analyze and preview python migrate_project.py /path/to/old/project --dry-run # Migrate in place (creates backup) python migrate_project.py /path/to/old/project # Migrate to new location python migrate_project.py /path/to/old/project --output /path/to/new/project ``` **Transforms:** - Moves skills from `.claude/skills/` to `skills/` - Creates `.claude-plugin/` with plugin.json - Generates VERSION, conftest.py, pytest.ini - Creates shared documentation --- ## Reference Projects Learn from production implementations: | Project | Skills | Type | Strength | |---------|--------|------|----------| | Jira-Assistant-Skills | 14 | Custom Library | Mock architecture | | Confluence-Assistant-Skills | 17 | Custom Library | Risk documentation | | Splunk-Assistant-Skills | 14 | Custom Library | Test infrastructure | ```bash # Show patterns from specific project python show_reference.py --project jira --topic client-pattern # Compare patterns across projects python show_reference.py --topic testing-patterns --compare-all # List available topics python show_reference.py --list-topics ``` --- ## Production Architecture The production pattern is **thin documentation wrappers around a publishable CLI library**: ``` my-project/ ├── .claude-plugin/ # Plugin manifest │ ├── plugin.json │ ├── marketplace.json │ └── commands/ # Slash commands ├── skills/ # Pure documentation │ ├── {topic}-assistant/ # Hub/router skill │ ├── {topic}-{skill}/ # Feature skills (SKILL.md only) │ └── shared/docs/ # SAFEGUARDS, QUICK_REFERENCE ├── {topic}-assistant-skills-lib/ # Optional: CLI library ├── conftest.py # Root test fixtures ├── pytest.ini # Test configuration ├── VERSION # Single version source └── CLAUDE.md # Project guidance ``` **Key principles:** - Skills are documentation, not code - Scripts live in separate library packages - Hub/router skill routes requests - Risk levels documented everywhere - VERSION is single source of truth --- ## Risk Level System All operations marked with risk indicators: | Risk | Symbol | Description | |------|:------:|-------------| | Safe | `-` | Read-only operations | | Caution | `⚠️` | Single-item modifications | | Warning | `⚠️⚠️` | Bulk/destructive operations | | Danger | `⚠️⚠️⚠️` | Irreversible operations | --- ## Related Documentation - [Quick Reference](./docs/QUICK-REFERENCE.md) - [Workflows](./docs/WORKFLOWS.md) - [Examples](./docs/EXAMPLES.md) - [Migration Guide](./docs/MIGRATION.md) --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/grandcamel) — claim your Tome and manage your conversions.
