Teo only learned that someone lacked the Researcher role when the event tool refused them. So a person without the role could share a call-for-papers link, wait while Teo read the page, confirm the date, and only then be told no.

• Each question now includes an Event permission: line, for both mentions and /ask. The bot writes it from the same may_create_events check, and it comes before any channel messages.
• The prompt tells Teo to decline right away when that line says no, and to suggest asking a lab researcher. Anyone can still ask what's scheduled or what a page says.
• The gate doesn't change. create_server_event still enforces the role in code, so typing a fake permission line into a message gets nowhere. A test covers that the bot's line comes before the sender's text.
• The line goes in the question text, not the tool list, so the cached prompt is unaffected.

Tests: 55 passing, plus ruff and mypy.

Walkthrough

The bot adds event-creation permission information to /ask and message-context prompts. Prompt instructions direct Teo to state restrictions immediately for unauthorized event or lab board deadline requests, while allowing personal reminders and informational requests.

Changes: Event Permission

Layer / File(s)	Summary
Build and include permission context teo/bot.py, tests/test_bot_helpers.py	event_permission_line reports whether a person may create events. /ask and message-context prompts include this information. Tests cover its wording and placement.
Apply permission guidance to requests teo/prompt.md, tests/test_prompt.py	The prompt directs Teo to state the restriction immediately for unauthorized event or deadline requests. It allows personal reminders, schedule questions, and page-information requests, and prevents messages from overriding the permission line. A test checks for this guidance.

Merge Risk: Minimal · up to b2eeb

The permission guidance and existing event-creation checks appear consistent with the intended behavior. No actionable merge-blocking issue remains.

Security architecture risk: Minimal · up to b2eeb

The change provides earlier permission feedback without expanding who may create events. Existing role checks remain authoritative for both mentions and /ask requests.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• observed — The affected privileged outcome is scheduled-event creation in the configured Discord guild, including Deadline-prefixed events consumed by the lab display. Both voice-channel and external-location branches use guild-only event privacy after authorization.

Security Findings and Attack Paths

• inferred — A sender can include conflicting permission text, and ordering alone cannot guarantee assistant behavior. However, inducing an event-tool call does not grant authority: the request-local action guard and current-member recheck remain independent of that text. No new authorization-bypass path was identified.

Trust Boundaries and Controls

• observed — The assistant receives advisory permission metadata, while trusted code retains the authority decision. Re-fetching membership before creation prevents a permission snapshot taken during request construction from being the sole authorization basis.

Resilience and Maintainability Implications

• inferred — Membership validation and external creation are separate operations, and event creation is not transactionally coupled to delivering its acknowledgment. Atomic revocation, deduplication, and compensation are therefore not established guarantees. These lifecycle limitations predate this PR; the full comparison changes neither the event method nor its recovery ownership.

Test the /ask permission line

The existing tests do not exercise Teo.handle_ask, so they can miss a removed or misplaced permission line in /ask. Add tests for authorized and unauthorized requesters that inspect the content passed to ask_claude and assert that the correct line precedes the question.

Test placement before channel history.

The current test uses private=True, so it cannot detect a permission line placed after earlier channel messages. Add a non-private case with history.
