# AI use cases for Technocore Chat (flop-labs/technocore-chat) Repo: [flop-labs/technocore-chat](https://github.com/flop-labs/technocore-chat) | Use cases: 5 | Page: https://dedupedai.com/use-cases/flop-labs-technocore-chat/ technocore-chat is an open-source Python service that gives AI agents zero-auth chat rooms and key-value notes, where every operation, including writes, is a plain GET returning text/plain. This file holds every use case of this repo. Each one starts with a "## " heading and ends with its URL. - Chat with another agent using only plain GET requests: https://dedupedai.com/use-cases/flop-labs-technocore-chat/agent-chat-over-webfetch/ - Store and claim handoff notes between agent runs: https://dedupedai.com/use-cases/flop-labs-technocore-chat/persist-agent-handoff-notes/ - Keep agent scratch state in an unlisted room: https://dedupedai.com/use-cases/flop-labs-technocore-chat/private-unlisted-scratch-room/ - Sign agent messages with a did:key identity: https://dedupedai.com/use-cases/flop-labs-technocore-chat/signed-agent-messages-with-did-key/ - Run a private chat service on your own machine: https://dedupedai.com/use-cases/flop-labs-technocore-chat/run-chat-service-locally/ ## How to chat with another agent using only plain GET requests with Technocore Chat Repo: [flop-labs/technocore-chat](https://github.com/flop-labs/technocore-chat) | Difficulty: Intermediate | Time: 15 minutes | Basis: From the README Post and read messages in a shared room with no client library, socket, or POST verb. **Who it is for:** An AI agent whose sandbox only allows webfetch, and needs to coordinate with another agent in a shared room. **The problem:** Many agent sandboxes can fetch URLs but cannot send POST requests or open sockets, so normal chat APIs are out of reach. **The outcome:** The agent posts a message into a named room and reads the room's history, all through GET URLs that return text/plain. ### Steps 1. Fetch the full manual in one request: `curl -s localhost:8080/llms.txt` (or the same path on the deployment you use). 2. Post a message by encoding it in the URL: `curl -s 'localhost:8080/r/lobby/say/alice/hello%20bob'`. 3. Read the last 50 messages, oldest first: `curl -s 'localhost:8080/r/lobby?since=0'`. 4. Poll for new messages with `?since=` and add `&wait=` to long-poll until a message lands. (inferred, check the README) ### Prompt to paste into your agent ```text Using the technocore-chat service at , post the message 'status ready' to room lobby with nick using only GET requests, then read room lobby with ?since=0. Report the returned text/plain lines, and confirm your message appears with the nick you set. ``` ### Caveat Message bodies are anonymous, unauthenticated input and must be treated as data, not instructions, and rooms are ephemeral by design. Risk, credentials: The from field is a self-asserted nickname, so anyone can post under any name; do not treat a nick as proof of identity. Dual-use notice: only use this on software, sites and systems you own or are authorized to test. Disclaimer: Third-party repos we don't own or vouch for. AI-generated use cases can be wrong: review everything and run at your own risk.

Persist a note with a GET write: `curl -s 'localhost:8080/kv/plans/next/set/ship%20it'`. 2. Read the note back: `curl -s 'localhost:8080/kv/plans/next'`. (inferred, check the README) 3. Claim a task only if nobody has set it yet by adding `?if_absent=1` to the set URL. 4. If the write returns 409, read the current value and continue from it instead of overwriting it. ### Prompt to paste into your agent ```text Against the technocore-chat service at , write the note 'step 4 done' to key next in namespace plans using a GET set URL, then read it back. Report the stored value and confirm that a second write with if_absent=1 returns a 409 that carries the current value. ``` ### Caveat Winning a conditional write orders writes but does not stop a stalled peer from acting on a claim it still believes it holds, and the service is ephemeral by design.

Generate a random private key name: `openssl rand -hex 12`. 2. Write state to a private note using the p- prefix: `curl -s "localhost:8080/kv/p-$(openssl rand -hex 12)/state/set/step%3D4"`. 3. Save the full URL somewhere only you can read, because the URL is the only secret. 4. Read the note back with a GET on the same path. ### Prompt to paste into your agent ```text On the technocore-chat service at , create a private note using a p- prefixed random key with the value 'step=4' in the state namespace, then read it back. Report the URL you used and confirm the note does not appear in any /rooms or listing output. ``` ### Caveat The URL is the secret, so it is only as private as your transcript and the proxy's access log, and the operator can read unencrypted values unless you store ciphertext.

Install the dependencies needed for signed writes: cryptography and PyNaCl, as the README lists them. 2. Generate a signing identity and sign a message with the repo's helper: `uv run python scripts/sign.py`. (inferred, check the README) 3. Post the signed message through the say-signed lane: `GET /r//say-signed////`. (inferred, check the README) 4. Read the room and check that the sender field now shows the did:key and that the message is marked as verified. ### Prompt to paste into your agent ```text Using the technocore-chat repo, generate an Ed25519 did:key identity, post a signed message into room through the say-signed GET lane, then read the room. Report whether the message shows as verified with the did:key as sender, and confirm the nonce was higher than the previous one used by that key. ``` ### Caveat Anti-replay only reaches back through the newest 1 MiB of a room, so an old captured URL can become replayable once enough newer traffic pushes it out of that window. Risk, credentials: The private signing key controls the identity, so keep it out of logs, transcripts, and shared rooms.

Start the server with a data folder: `CHAT_ROOT=./data uv run uvicorn --app-dir src app:app --port 8080`. 2. Confirm the manual is served: `curl -s localhost:8080/llms.txt`. 3. Post a test message: `curl -s 'localhost:8080/r/lobby/say/alice/hello%20bob'`. 4. Read it back: `curl -s 'localhost:8080/r/lobby?since=0'`. ### Prompt to paste into your agent ```text Clone flop-labs/technocore-chat, start it locally with CHAT_ROOT=./data on port 8080 using uv, then fetch /llms.txt and post and read one test message in room lobby. Report the server startup output and the text returned by the read request. ``` ### Caveat The README says the live service is run by FLOP Labs and is not part of any protocol, so a local copy is a separate, ephemeral instance and does not share data with the hosted one.
