T3AA tools

T3AA adds 14 tools to the AI agent when AI Foundation is present. You do not have to name a tool: the agent picks it from your request. The tables below show:

In the agent: the name you see in the / picker, in steps, and on preview cards. You can also describe the task in your own words.
Tool: the technical name (t3aa_…), shown when you expand a step, in AI Foundation > AI Agent > Audit, and in external MCP clients.
Kind: Only reads or Asks before changing.

The / picker in the AI agent lists tools by their name in the agent

Approve alt text drafts	`t3aa_alt_text_approve`	Approves drafts so they become the live alternative text. You can approve selected drafts or all pending drafts.	Asks before changing	AI Alt Text
Read file metadata	`t3aa_get_file_metadata`	Reads alt text, title, description, and `public_url`. The agent must quote `public_url` and never invent a URL.	Only reads	AI Alt Text
Update file metadata	`t3aa_update_file_metadata`	Generates or updates alt text, title, and description (DualMode + previewable). If the file already has texts, the agent can offer Regenerate all, Fill empty fields only, or Keep current texts.	Asks before changing	AI Alt Text

Get file for metadata (MCP)	`t3aa_get_file_for_metadata`	Returns a fetchable image URL plus current metadata for external vision. Hidden from the agent UI; available to MCP clients.	Only reads	AI Alt Text

Alt-text flow: list missing → queue folder → drafts list → approve / mark decorative.

Accessibility scans and Fix Hub

In the agent	Tool	What it does	Kind	Feature
Run accessibility scan	`t3aa_accessibility_scan_run`	Runs a WCAG accessibility scan for a page and returns score and issues. Uses the scan quota of the license.	Asks before changing	Scanner
Show accessibility issues	`t3aa_accessibility_issues`	Shows score and issues from the last scan of a page. Only reads — it never starts a new scan.	Only reads	Fix Hub
Suggest accessibility fixes	`t3aa_accessibility_fix_suggestions`	AI fix suggestions for issues from the last scan (what to change, corrected HTML, why). Does not mutate the page.	Only reads	Fix Hub

Asking “What accessibility issues does this page have?” or “Check this page for accessibility problems” only reads the last scan result. Asking “Scan this page for accessibility problems” or “Run a WCAG scan on this page” opens a scan preview and asks you to confirm before it runs.

Performance, content, and media

In the agent	Tool	What it does	Kind	Feature
Check page speed	`t3aa_get_page_speed`	Fetches Google PageSpeed Insights scores (performance, accessibility, SEO, best practices) for a page URL. The result is not saved to the T3AA Lighthouse report in the backend.	Only reads	Lighthouse / PageSpeed
Summarize content	`t3aa_summarize_content`	Summarizes or simplifies content (DualMode). A named page number is passed as `pageId`; a named language (for example German) is passed on. The tool returns text — it does not write the page by itself. If the agent then offers to save the text on the page, that is a separate write preview (Apply / Cancel).	Only reads (write only after a later Apply)	Content · Simplified Text
Generate voice-over	`t3aa_generate_voice_over`	Creates an MP3 voice-over with AI text-to-speech from text or from a page. Uses the editor’s default audio provider (OpenAI or ElevenLabs).	Asks before changing	AI Voiceover
