Tessl Tile Discovery (during planning)

1. Check Tessl Availability

• Unix/Linux/macOS: command -v tessl >/dev/null 2>&1
• Windows PowerShell: Get-Command tessl -ErrorAction SilentlyContinue

If not available: display info message once, continue without tiles.

2. Check Status

mcp__tessl__status()

3. Extract Technologies from Technical Context

From the drafted plan, identify: Language/Version, Primary Dependencies, Storage, Testing, any other frameworks/libraries.

4. Search and Install Tiles

For each technology:

1. mcp__tessl__search(query="<technology>")
2. Identify tile type: Documentation (has describes), Rules (has rules), Skills (has skill)
3. mcp__tessl__install(packageName="<workspace/tile-name>")
4. Document in research.md:

## Tessl Tiles

### Installed Tiles

| Technology | Tile | Type | Version | Eval |
|------------|------|------|---------|------|

### Technologies Without Tiles

- <technology>: No tile found

5. Query Best Practices

For each installed documentation tile:

mcp__tessl__query_library_docs(query="best practices for <library>")

Incorporate findings into research.md.

5.5. Fetch Eval Results

For each installed tile, fetch eval scores:

bash .tessl/tiles/tessl-labs/intent-integrity-kit/skills/iikit-core/scripts/bash/fetch-tile-evals.sh --json <workspace/tile-name>

Windows: pwsh .tessl/tiles/tessl-labs/intent-integrity-kit/skills/iikit-core/scripts/powershell/fetch-tile-evals.ps1 -Json <workspace/tile-name>

• Include eval scores in the research.md Tessl Tiles table (add Eval column)
• If a technology has multiple tile options: prefer the one with higher eval score
• Full eval results are saved to .specify/evals/ for dashboard consumption

Update the research.md table format to include eval data:

## Tessl Tiles

### Installed Tiles

| Technology | Tile | Type | Version | Eval |
|------------|------|------|---------|------|
| FastAPI | tessl/pypi-fastapi | docs | 1.2.0 | 92% (3 scenarios) |

6. Catalog Skills

Record available skills from installed tiles for use in /iikit-08-implement.

7. Failure Handling

• Network issues / registry unavailable / auth required: log warning, continue without affected tiles
• No results: note in research.md, continue
