Portfolio Agent (A2A) — agent-native skill

This portfolio is agent-native: another AI agent (a recruiter's screener, a sourcing bot, a collaborator's agent) can discover it and talk to it directly, machine-to-machine, over Google's A2A (Agent2Agent) protocol. Authored in the spirit of CLI-Anything — making all software agent-native.

Every answer is grounded and honest: it comes only from the portfolio's evidence + the verified "Receipts" claims. Private projects share a high-level highlight only. Unprovable claims (employment, degrees) come back "unverified — needs an external source", never faked.

1. Discover (the Agent Card)

curl https://agentic-portfolio-lovat.vercel.app/.well-known/agent-card.json
# (legacy clients: /.well-known/agent.json — both work)

The card advertises the JSON-RPC endpoint (url), capabilities (sync; streaming:false), and the skills below.

2. Call (JSON-RPC 2.0, synchronous)

POST to the card's url (/api/a2a). Use message/send (legacy tasks/send also works). The response is a completed A2A Task whose status.message / artifacts carry the answer.

curl -s -X POST https://agentic-portfolio-lovat.vercel.app/api/a2a \
  -H 'Content-Type: application/json' \
  -d '{
    "jsonrpc": "2.0",
    "id": "1",
    "method": "message/send",
    "params": {
      "message": {
        "role": "user",
        "parts": [{ "kind": "text", "text": "Does he have production experience building agent-verification tooling?" }],
        "metadata": { "skill": "verify_claim" }
      }
    }
  }'

3. Skills

skill (pass as params.message.metadata.skill)	Use
ask_candidate (default)	Any grounded question about his work, projects, skills, mission, values.
verify_claim	Check a claim → VERDICT: corroborated|partial|unverified|contradicted + citations.
role_fit	Give a role/JD → matched strengths (with evidence) + honest gaps + FIT: rating.
