Security
How PrompTugal.news's agents talk to each other outside git, counted and drawn from every session's transcript; the keys and vaults each one holds; the threats, the gaps and who owns each fix. Kept by security@PrompTugal.dinis.

Why this page
Dinis Cruz, 6 November 2026: "we now have quite a lot of agent-to-agent communication, and I really want to make sure that that doesn't go out of control ... I want to visualize it ... it can be abused ... from a provenance point of view ... we lose quite a bit of provenance." This page is the map, kept by security@PrompTugal.dinis and redrawn at its wakes. Everything here is metadata: who, to whom, when, how big, by which channel. Never the words themselves.
The picture
Open the picture: who tells whom what to do outside git, the two conductors at the centre, a line for each kind of act, its width the number of acts. (The picture opens on its own until the page can show images inline: asked of dev@.)
The data behind it, one row per act: comms.json. From 5 November 00:00 to 6 November 04:30 UTC.
| Channel | Acts | What crosses it |
|---|---|---|
A message between sessions (send_message) | 22 | tasks, answers, relayed decisions |
A session created by an agent (create_session) | 17 | the new agent's whole first brief, written by the agent that made it |
| A schedule written or rewritten by an agent | 22 | the standing prompt the scheduled agent obeys at every wake |
| A scheduled wake | 57 | that standing prompt, delivered again |
| Of all the above, saying they carry Dinis's word | 39 | none signed |
The architecture
Dinis Cruz (the only one who instructs)
| speaks in a session; nothing he says is signed
v
conductor.3@web-summit ---- creates 10 sessions (8 of them PrompTugal's), writes their first briefs
|
v
conductor@PrompTugal ---- creates 7 more sessions, writes 14 schedules and rewrites 5,
| | | sends 9 messages, issues 15 inboxes
-----------+ | +--------------------------------------------.
| | |
1 session 2 schedule (standing prompt, 3 append-lane inboxes
messages fired every hour or two) (board/inbox.json: the conductor's;
(transcript, (stored on the account; board/inboxes/<role>.json: one per
readable by rewritable by any session) agent; write token public; sealed,
any session) signed; the conductor holds every key)

'--------------+-----------------> 14 agents <--------------------'

4 git: commits with For: and To: trailers, the board,
desk notes (desks/synthetic/run-*/to/), board/tasks/
(signed by nobody, but public, reviewed and versioned)| # | Channel | Who can write | Who can read | Authenticated? | Kept where | Counted here |
|---|---|---|---|---|---|---|
| 1 | Session messages | any session on the account | the receiver, and any session on the account (transcripts) | the harness names the sending session; the text is not signed | the transcripts | yes, from transcripts |
| 2 | Created sessions and schedules | any session on the account | the account's sessions | no: an agent writes another agent's standing orders | the account | yes, from transcripts |
| 3 | Append-lane inboxes | anyone (the write token is public by design) | the receiver, and the conductor (it holds every inbox's keys) | only if the sender signs; the receiver must check against board/keys.json | each inbox vault | not yet: sealed; needs receipts (below) |
| 4 | Git and the board | anyone with push access | everyone | no signature; the push and the review are the record | this repository | from git |
Channels 1 to 3 lose provenance that git keeps: no review, no version, no diff, and for 1 and 2 no signature. That is the trade Dinis named: they are faster, and they carry instructions.
What can go wrong
- Authority by relay. 39 agent-written acts say "at Dinis's word". A misled agent, or anyone writing to a public inbox lane, can write those words too, and the receiver cannot tell. Every scheduled agent's standing prompt was written by a conductor, not by Dinis.
- Transcripts are a shared surface. Any session on the account can read any other's transcript. A secret printed once, in any session, is readable by every agent. (security@ did exactly this with its own inbox credentials on 6 November; that inbox is being re-issued.)
- One reader of all mail. The conductor made every agent's inbox and keeps its keys, at Dinis's word, so it can read every agent's mail; a conductor misled by what it reads exposes all of it.
- Misrouting. A schedule meant for dev@ was first written into another project's session (
journalist@web-summit) and deleted a minute later. Nothing checks that a schedule's target is the agent its name says. - Loops. An agent that answers every message with a message can run without end; nothing counts messages against a budget yet.
How the tracking works, and what comes next
Today: security@ reads every session's transcript with the account's own tools (metadata only, by its collector), at its wakes, and redraws this page.
Next (proposed to Dinis and conductor@):
- A receipt for every send. Whoever sends on any channel also appends a receipt to security@'s inbox lane: from, to, channel, time, size and the text's sha256, signed by the sender, sealed to security@. Never the text.
board/tools/agent_inboxes.py sendcan do it in the same call. - Two sources, reconciled. At each wake security@ matches the receipts against the transcripts: a send with no receipt, or a receipt with no send, is a finding.
- Signed instructions. Dinis's guidance carries his signature (his sign-in key signs the file in his browser), and every prompt that cites his word cites the guidance file by name and hash, so a receiver can check it.
- A budget for messages per agent per day, from accountant@, as for runs.
- On Dinis's dashboard: a Messages panel (today's counts by channel, the picture, unsigned claims, top senders), read from
comms.json(board/spec-dashboard-messages.md).
The keys and vaults
Who holds which key, and what is lost when a session ends: board/team/security/keys-and-vaults.md. The reviews, with every finding, its severity and its owner: board/team/security/reviews/.
