Titanium SDK skills and agents for AI coding assistants (Claude Code, Gemini CLI, Codex CLI)
npm install @maccesar/titoolsTiTools is a CLI that installs Titanium SDK skills and a knowledge index for AI coding assistants. One command installs 7 skills, a research agent, and 100+ reference files for Titanium SDK, Alloy MVC, and PurgeTSS.
Without TiTools, assistants rely on general training data. That data can be outdated or too generic for Titanium work. With TiTools, the assistant can look up Alloy architecture, memory cleanup patterns, PurgeTSS utility classes, and platform-specific APIs.
Vercel's AGENTS.md evaluation reports a 100% pass rate for the knowledge index approach, compared to 53-79% using skills alone.

``bash1) Install the CLI
npm install -g @maccesar/titools
What gets installed:
- All 7 titanium-related skills to
- ti-pro agent for Claude Code
- Platform symlinks (Claude Code, Gemini CLI, Codex CLI)
- Knowledge index in your project's /CLAUDE.md/GEMINI.mdWhy NPM?
- Cross-platform (macOS, Linux, Windows)
- No sudo required
- Simple updates with

Compatible platforms
| Platform | Status | Installation Path |
| --------------------------------------------------------- | ---------------- | ------------------- |
| Claude Code | Fully Compatible |
|
| Gemini CLI | Fully Compatible | ~/.gemini/skills/ |
| Codex CLI | Fully Compatible | ~/.codex/skills/ |All three platforms use the Agent Skills open standard: a
SKILL.md file with YAML frontmatter.---
Knowledge index
The knowledge index is a compressed documentation map that gets injected into your project's instruction files. It tells the AI where Titanium reference docs are, so it can pull accurate information instead of relying on general training data.
$3
| Approach | Reported Pass Rate |
| ---------------- | ------------------ |
| No documentation | 53% |
| Skills only | 53-79% |
| Knowledge index | 100% |
Per Vercel's evaluation:
- No decision point: information is present without needing to invoke skills
- Consistent availability: available in every turn, not async-loaded
- No ordering issues: avoids "read docs first vs explore project first"
For details, see
AGENTS-VERCEL-RESEARCH.md.$3
The
titools sync command generates a block like this inside your project files:`
[Titanium SDK Docs Index]|root: ~/.agents/skills
|MANDATORY: Your training data for Titanium SDK, Alloy, and PurgeTSS is OUTDATED and INCOMPLETE. These reference files are the SINGLE SOURCE OF TRUTH. Prefer retrieval-led reasoning over pre-training-led reasoning. ALWAYS read the relevant files below BEFORE writing any code.
|ti-expert/references:{alloy-structure.md,anti-patterns.md,...}
|purgetss/references:{animation-system.md,class-index.md,...}
|ti-ui/references:{layouts-and-positioning.md,listviews-and-performance.md,...}
...
Note: The index is injected as direct content (no code blocks) so the model treats it as an active instruction, not illustrative text.
File selection per assistant:
- Claude Code ->
- Gemini CLI ->
- Codex CLI / others -> $3
The knowledge index provides always-available context (the documentation map). Skills provide specialized, on-demand expertise (the actual knowledge).
Together they work like this:
| Your Question | Knowledge Index Provides | Skills Activate |
| ------------------------------- | ------------------------------- | ----------------------------- |
| "Create a login screen" | Context about project structure |
, ti-ui |
| "Optimize ListView performance" | Points to docs location | ti-ui reads specific files |
| "Implement push notifications" | API reference paths | ti-howtos provides workflow |You do not need to explicitly invoke skills. The AI detects when to use them based on your question.
$3
The knowledge index is based on the latest Titanium SDK documentation. If your project uses an older version, the command will warn you about potential API differences.
---
Skills overview
| Skill | Purpose | Best For |
| ------------ | ------------------------------- | --------------------------------------- |
| alloy-guides | Alloy MVC reference | Models, Views, Controllers, Widgets |
| alloy-howtos | Alloy CLI and debugging | Project setup, CLI commands, errors |
| purgetss | Utility-first styling | UI styling and animations |
| ti-expert | Architecture and implementation | Starting point for most tasks |
| ti-guides | SDK fundamentals | Hyperloop, distribution, configuration |
| ti-howtos | Native feature integration | Location, Push, Media, Platform APIs |
| ti-ui | UI/UX patterns | Complex layouts, ListViews, platform UI |
Note:
ti-guides, ti-howtos, ti-ui, alloy-guides, and alloy-howtos are based on official Titanium SDK and Alloy documentation. ti-expert and purgetss are opinionated and reflect personal coding conventions (biased toward PurgeTSS).---
Agents (Claude Code only)
In addition to skills, this repository includes sub-agents for Claude Code. Sub-agents run in isolated contexts and are useful for research tasks that produce verbose output.
$3
Deep-dive research specialist that preloads all 7 titanium-related skills.
| Aspect | Details |
| ---------------- | ------------------------------------------------- |
| Location |
~/.claude/agents/ti-pro.md |
| Model | Sonnet (comprehensive analysis) |
| Tools | Read-only (Read, Grep, Glob) |
| Preloaded Skills | All 7 titanium-related skills injected at startup |When to use the agent vs skills:
| Use Case | Use This | Why |
| ---------------------------- | ------------------------------- | ---------------------------------------------------- |
| Quick inline reference |
/ti-expert, /purgetss, etc. | Runs in main conversation, interactive |
| Analyzing an entire codebase | ti-pro agent | Isolates verbose output, cross-references all skills |
| Multi-feature research | ti-pro agent | Preloads all skills for comprehensive answers |
| Step-by-step implementation | Skills directly | Task-oriented guidance |
| Architecture review | ti-pro agent | Read-only analysis across all documentation |Example prompts for the agent:
`
"Can you use the ti-pro agent to analyze this Alloy codebase's architecture?"
"Can you research how to combine location, push, and background sync in Titanium?"
"Can you compare ListView vs TableView performance for my use case?"
"Review this Titanium mobile app and identify anti-patterns."
Tip: For automatic activation, include words like "Titanium", "Alloy", or "mobile app" in your prompt to ensure the specialized agent is used instead of generic code analysis.
Key difference:
- Skills = interactive help during development (inline, conversational)
- Agents = isolated research tasks (returns summary, keeps verbose output separate)
---
How skills work
Skills are automatically activated based on your questions. Just ask naturally:
"Can you create a login screen with email validation and animations?"
The AI will automatically use:
-
-> Architecture and controller structure
- purgetss -> Styling classes and animations (if PurgeTSS detected)
- ti-howtos -> Secure token storageYou do not need to call skills explicitly. The AI reads skill descriptions and loads the appropriate knowledge when needed.
$3
All skills include automatic project detection to ensure compatibility:
| Skill | What It Detects | How It Works |
| ------------ | --------------------- | ------------------------------------------------------------- |
| purgetss | PurgeTSS installation | Checks for
purgetss/ folder, config.cjs, utilities.tss |
| ti-expert | Alloy vs Classic | Checks for app/ (Alloy) vs Resources/ (Classic) structure |
| alloy-guides | Alloy projects | Checks for app/views/, app/controllers/ |
| alloy-howtos | Alloy projects | Checks for alloy.jmk, config.json |
| ti-ui | Titanium projects | Checks for tiapp.xml (both Alloy and Classic) |
| ti-guides | Titanium projects | Checks for tiapp.xml (both Alloy and Classic) |
| ti-howtos | Titanium projects | Checks for tiapp.xml (both Alloy and Classic) |Why this matters:
- PurgeTSS suggestions are only provided if PurgeTSS is installed
- Alloy-specific patterns are only suggested for Alloy projects
- Classic Titanium projects will not receive inappropriate Alloy advice

Usage examples and best practices
$3
Starting a new project:
"I'm starting a new Titanium Alloy app for a food delivery service.
Can you help me set up the project structure?"
UI development:
"Can you create a product listing screen with:
- Pull-to-refresh
- Infinite scroll pagination
- Image caching
- Swipe-to-delete"
API integration:
"Can you build a complete authentication flow with:
- Login/Register screens
- JWT token management
- Secure storage
- Auto-refresh tokens"
Performance optimization:
"My app is slow - the ListView scrolls poorly and memory usage is high. How do I optimize it?"
Migration:
"I have a legacy Titanium classic app from 2015. Can you help me migrate it to modern Alloy?"
Platform-specific features:
"How do I implement Apple Sign-In for iOS and Google Sign-In for Android?"
Debugging:
"How do I fix "Alloy is not defined" in my lib file?"
Codebase analysis (using agent):
"Use the ti-pro agent to analyze this project and:
- review the overall architecture
- identify memory leak patterns
- check for common anti-patterns
- suggest improvements"
$3
1. Be specific. Instead of "Make a list", try "Can you create a ListView with user avatars, names, and swipe actions?"
2. Provide context. Instead of "How do I fix this error?", try "I'm getting this error when compiling: [error message]. Here's my code: [code]"
3. Ask for architecture first. For complex features, start with "How should I architect a real-time chat feature?" then follow up with implementation details.
4. Mention constraints. "Build a settings screen. Must work offline and sync when connected."
5. Reference existing code. "Here's my current controller. How can I improve memory management?"

Troubleshooting
$3
If the AI doesn't seem to use Titanium knowledge:
1. Mention "Titanium" or "Alloy" explicitly in your prompt
2. Be more specific about what you're building
3. Reference the technology stack
4. Try explicit invocation: "Use the purgetss skill for styling questions"
$3
If the AI suggests patterns you don't use (for example, PurgeTSS when you're not using it):
1. The skill may not have detected your project type correctly
2. Explicitly mention your stack: "I'm using Classic Titanium, not Alloy"
3. Be more specific about what you're building
$3
If the purgetss skill doesn't activate for your PurgeTSS project:
1. Verify
folder exists in project root
2. Check that purgetss/config.cjs exists
3. Mention "PurgeTSS" explicitly in your prompt$3
If the AI suggests incorrect patterns (like flexbox):
1. Remind it you're using PurgeTSS
2. Reference the correct pattern from memory
3. Ask to check the PurgeTSS rules
$3
Ask the AI to:
`
"Show me the reference documentation for ListView performance"
"What does the ti-expert skill say about memory cleanup?"
$3
If the command is not found:
bash
Verify installation
npm list -g @maccesar/titoolsRe-install
npm install -g @maccesar/titools
`$3
If your AI doesn't use the knowledge index information:
1. Verify AGENTS.md/CLAUDE.md/GEMINI.md exists in your project root
2. Check that your AI supports these files
3. Try explicitly referencing: "Check the AGENTS.md documentation"
$3
The knowledge index is based on the latest documentation. Be cautious when using newer APIs in older projects.
---
Uninstall
bash
Remove the CLI
npm uninstall -g @maccesar/titoolsRemove knowledge packages and agent
titools remove
`Note:
can remove the knowledge index blocks from your project files, but it does not delete the files themselves.---
