    What we cover

    • Setting up a local retrieval engine and pointing it at a folder of documents
    • Giving an agent a search tool, and reading what it does with it
    • Knowing when you should care about embedding, chunking and reranking
    • Checking answers against sources so you know when to trust them

    Prerequisites

    You needWhy
    A MacSearchAF and the tunnel client are macOS today
    SearchAF, runningIt ingests your folder into a local Antfly index
    A folder of documentsThe knowledge base, or the sample corpus that ships in the bundle
    OpenAI API billing and a keyThe model runs on the API, not on a ChatGPT subscription
    Tunnel permissions, Read and ManageThe deployed agent reaches your Mac through a secure MCP tunnel
    ChatGPT Sites accessWhere the agent is deployed
    CodexIt follows the handoff and does the setup with you
  6. 06

    Get the bundle

    Everything today comes from one repository: the handoff, the gateway, the app starter, and the Atlas files.

    terminal
    git clone https://github.com/antflydb/antfly-agent-workshop.git
cd antfly-agent-workshop

    Project Atlas, the sample corpus

    Four short fictional documents about a product pilot, written so the questions have checkable answers.

    FileWhat it says
    atlas-approved-plan.mdThe pilot launches October 15, 2026 with 25 customers. Priya Shah owns launch, Omar Chen owns rollback. No budget is recorded.
    atlas-draft.mdAn earlier draft proposing October 1 for 50 customers, marked superseded
    atlas-meeting.mdA meeting confirming the approved plan; no public launch date, no budget
    untrusted-note.mdAn imported note containing instructions to the agent and a made-up million-dollar budget

    Build the Knowledge agent

  14. 14

    Bootstrap the starter

    Codex checks the machine, then copies the Knowledge starter into a new working directory.

    agent harness

    1. Read guides/searchaf-agent/AGENT-HANDOFF.md in the antfly-agent-workshop repository. Check this Mac for SearchAF running, Node 22.13 or newer, Python 3.12 or uv, and tmux. Tell me what's missing and what you can install. Don't install anything yet.

    2. Bootstrap the knowledge agent into a new directory called antfly-files-workshop in my home folder, then set up its Python environment and install the site's dependencies. Do not touch my SearchAF configuration.

  15. 15

    Confirm the corpus

    The gateway has to return passage text. A filename alone means indexing isn't done.

    terminal
    local/.venv/bin/python local/configure.py --root "$PWD/sample-data"
local/.venv/bin/python local/check.py --query 'Atlas pilot launch October' --expect 'October 15'
    agent harness

    1. Add the working copy's sample-data folder in SearchAF and wait for indexing, then configure the gateway with that folder as its only root and run the known-passage check for the October 15 launch date. Show me the check's output.

    2. Run one query that should return nothing from this corpus and confirm the gateway returns no excerpts.

  16. 16

    Start the gateway and tunnel

    terminal
    local/.venv/bin/python local/install_tunnel.py
local/.venv/bin/python local/tunnel.py start
local/.venv/bin/python local/tunnel.py status
    agent harness

    1. Install the pinned tunnel client, then walk me through creating a tunnel in my Platform organization and putting the key, tunnel ID, and model into the private env file. Never ask me to paste the key into this chat.

    2. Start the tunnel runtime and show me its status. If the default alias is taken, pick a unique one and tell me what it is. I'll need it to stop the tunnel later.

  17. 17

    Run the smoke test

    One real question through the whole path, before the app exists.

    terminal
    cd site
node --experimental-strip-types smoke-answer.mjs \
  --question 'When does the approved Project Atlas pilot launch? Cite the approved plan.' \
  --expect 'October 15'
    agent harness

    1. Run the smoke test from section four of the handoff with the approved-plan launch question. Show me the source count, the citation count, and whether the expected date was found. Do not print excerpt text.

  18. 18

    Deploy to Sites

    terminal
    cd site
npm test && npm run typecheck && npm run build
    agent harness

    1. Following section six of the handoff, create a new owner-only site for this app, write its project ID into the hosting file, and configure the key as a secret plus the tunnel ID and model. Then package, save a version, and deploy privately. Tell me the URL when it is live.

    2. Open the deployed URL, confirm I have to sign in, and confirm an unauthenticated request to the ask endpoint is denied.

  19. 19

    Knowledge: Ask your workspace

    The Knowledge agent's empty form: one question box, with example questions beneath it and the source panel waiting on the right

  20. 20

    Knowledge: The answer and its sources

    The Knowledge agent answering a question, with the cited sources listed beside the answer and each source labeled cited or retrieved

  21. 21

    Checking the answers

  22. 22

    What the app enforces

    • The model must search: an answer with no tool call is rejected
    • Every citation id is real: it is a hash of a passage the gateway returned
    • With no evidence or no citation, the app fails closed with a plain message
  23. 23

    What the app can't check

    Whether the passage says what the sentence next to it claims.

    • Any claim can carry any valid citation
    • Free-text fields carry no citation at all
    • A correctly cited proposal can still be presented as a decision
  24. 24

    Inspect and challenge

    Open the cited passages and read them.

    1. Ask what changed from the draft to the approved plan. Which date did the agent call approved?
    2. Ask about the approved budget.

    Meeting Prep: The brief

    The Meeting prep agent's brief: what to know, prior decisions and proposals with status labels, gaps, and a suggested agenda

    Wrapping up

  33. 33

    Stop and restart the tunnel

    Stop the tunnel. Ask the app something. Restart it. Ask again.

    terminal
    local/.venv/bin/python local/tunnel.py stop
local/.venv/bin/python local/tunnel.py start
    agent harness

    1. Stop the tunnel and confirm it is no longer reachable, then tell me what my app shows when I ask a question now.

    2. Restart the tunnel, run the known-passage check and the smoke test again, and confirm both pass.

    3. Show me the exact commands I run to stop everything when I am done, in order, including the alias if we changed it.

  34. 34

    Close and take-home

    Write down three things: your result, what it could not answer, and your next action.

    agent harness

    1. Using ACCEPTANCE.md, record my result, the question the index could not answer, and my next action. Do not include excerpt text or filenames from my personal folder.

    2. At home: bootstrap the meeting-prep agent into a second directory that reuses my existing index and tunnel. Do not restart or repoint the current connection.
