What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of ai.aitana.chat controls every word below.

Knowledge Search

Search a private document corpus (Vertex AI Search) and answer questions with cited sources. Use when the user asks about content that lives in the indexed corpus — contracts, reference material, internal documents — rather than the open web. This is the enterprise-search counterpart to the Web Researcher skill: same "search then cite" behaviour, private corpus instead of the public web.

searchknowledge-base

Web Researcher

Search the web, summarize findings, and answer research questions. Use when the user asks about current events, needs web research, or wants information from online sources. NOT for electricity market / day-ahead / spot prices for a bidding zone (DK1, SE3, FR …) — the PPA specialist queries the ENTSO-E price database directly and returns real, cited hourly figures. Route price questions there, not here.

Assistant (GPT Luna)

A balanced everyday assistant on OpenAI's fast tier (GPT-5.6 Luna) — quick and capable for general help, questions, drafting, and light analysis. The middle-tier counterpart to the Deep Reasoner (GPT Sol); pick this for speed/affordability, the reasoner for the hard ones.

generalmiddle-tier

Deep Reasoner (GPT Sol)

A slow, careful, in-depth reasoner for hard problems — multi-step analysis, ambiguous questions, weighing trade-offs, reasoning through a document or a decision. Runs on OpenAI (GPT). The OpenAI counterpart to the Claude "Deep Reasoner" — same job, different model, so you can compare providers on the same task. Use when you want depth and rigor over speed.

reasoninganalysis

Deep Reasoner (Claude)

A slow, careful, in-depth reasoner for hard problems — multi-step analysis, ambiguous questions, weighing trade-offs, reasoning through a document or a decision. Runs on the smart (Anthropic Claude / reasoning) tier. Use when you want depth and rigor over speed.

reasoninganalysis

General Assistant

General-purpose AI assistant for everyday tasks. Use as the default skill when no specialized skill matches the user's request.

general

Document Analyst

Analyze documents, extract structured data, and answer questions about uploaded files. Use when the user uploads a document, asks about file contents, or requests data extraction.

Assistant (Claude Sonnet)

A balanced everyday assistant on Anthropic's middle tier (Claude Sonnet 5) — quick and capable for general help, questions, drafting, and light analysis. The middle-tier counterpart to the Deep Reasoner (Claude Opus 4.8); pick this for speed/intelligence balance, the reasoner for the hard ones.

Document Writer

Write a real document — Word (.docx) and other Office formats — into the user's workspace, styled in their organisation's house style by default, or after a template document they already have. Use when the user asks to create, draft, write up or produce a document, report, memo, letter or offer as a FILE rather than as chat text.

A2A protocol extensions the card declares. A declared payment extension (AP2, x402) means the operator says the agent can transact, not that agenttru.st has seen it do so.
Card completeness: a2a.proto v1.0 requires eight top-level fields. This card omits:
supportedInterfaces

Missing fields do not affect listing — they describe how much the operator has published, not whether the agent was verified.
