Discord Recipient Routing

Use this skill before every recipient-specific Discord DM, handover, report, assessment, or confidential-content send where an approved user says “tell Engineer X”.

This is a collaboration-routing procedure, not a requester-authentication or general security system. Host policy and terminal/admin controls decide which users are trusted and allowed to instruct the agent. This skill makes sure the message is addressed to the intended approved engineer rather than a similarly named colleague.

Boundaries

• Resolve the recipient only from this agent's active approved roster. Never use memory, prior DMs, display-name search, fuzzy matching, inferred routes, or a “closest” colleague.
• Keep names, Discord IDs, roster locations, and organisations out of this shared skill. Put them in the per-agent control manifest.
• Do not record message bodies, secrets, tokens, or unnecessary personal data.
• This skill does not authenticate the requester, intercept arbitrary sends, or independently prove that Discord displayed a message. It governs deterministic target selection and delivery-target verification.

Required Inputs

Obtain one explicit instruction naming one recipient. Load this agent's approved roster. The roster must map each canonical recipient name to one immutable Discord user ID and indicate whether that recipient is active and can receive a relay.

The agent must not infer an intended recipient from a partial name, a nickname, a display name, or prior chat history.

Routing Procedure

1. Match the requested recipient text exactly against the roster's canonical recipient name.
2. Continue only when there is exactly one active, relay-eligible match with a valid Discord user ID.
3. Construct the target as user:<discordUserId>.
4. Send the message only to that exact target. Do not substitute a channel, search result, display name, or another recipient.
5. Inspect the message-tool response and verify the reported target matches the expected exact target.
6. Record only non-content delivery evidence: requested recipient, canonical recipient, target ID, platform message ID when available, and delivery result.

If there are zero matches, multiple matches, an inactive recipient, an invalid ID, or a missing/mismatched delivery target, send nothing and ask one targeted clarifying question or report the mismatch.

Delivery Contract

A recipient-specific relay may be claimed as sent only when:

• the roster yielded one exact active recipient;
• the message was addressed to that recipient's immutable Discord ID; and
• the tool response confirms the same target.

If the platform cannot expose enough non-content receipt information, state that delivery target confirmation is unavailable. Do not claim a stronger guarantee than the platform evidence supports.

Integration Contract

• Trusted-user admission remains a host/workspace policy concern.
• The local approved roster is scoped to one agent/machine and is the only recipient authority.
• No attribution prefix, requester-identity check, pause-state file, or before_tool_call hook is required by this skill.
• Higher-risk workflows may add their own controls, but they must not weaken the exact-recipient rule above.

Validation

Before release or integration, run deterministic non-production fixtures that cover:

• one exact active recipient resolving to the expected user:<id> target;
• zero and multiple exact matches;
• inactive recipient;
• invalid Discord ID;
• attempted target substitution; and
• delivery-target mismatch.

Acceptance Criteria

For “tell Engineer X”, the agent either sends to Engineer X's immutable roster ID and verifies that target in the delivery receipt, or it sends nothing and reports the exact ambiguity or mismatch.
