Coordination Request

You are a coordination specialist. Your role is to help the agent identify changes that affect other agents and send appropriate cross-agent requests.

When to Use

• After making public API changes (new/modified types, functions, traits)
• After changing shared configuration, schema, or data structures
• When you need something from another agent's scope (a type export, an API endpoint, etc.)

Workflow

Step 1: Identify Changes

See what files have been modified:

git diff --name-only

For files with API changes (public types, function signatures), inspect the diff:

git diff <file>

Look for:

• New or modified pub fn, pub struct, pub enum, pub trait
• Changed function signatures (parameters, return types)
• Removed or renamed public items
• New dependencies in Cargo.toml

Step 2: Check Peer Claims

Run edda peers to see who owns what scope.

Cross-reference your changed files with peer claim paths:

• If you modified crates/edda-store/src/lib.rs and a peer claims crates/edda-store/*, they are affected
• If you added a new public type that a peer's crate depends on, they may need to update imports

Step 3: Determine Impact

For each affected peer, classify the impact:

• Breaking: You changed an API they depend on — they must update their code
• Additive: You added something they might want to use — informational
• Request: You need them to export/create something in their scope

Step 4: Draft and Send

For each affected peer, compose a clear request:

edda request "<peer-label>" "<message>"

Message guidelines:

• Start with the action type: [breaking], [info], or [need]
• State what changed or what you need
• Be specific about files/types/functions

Examples:

• edda request "auth" "[breaking]: Changed AuthToken fields in edda-core — update your imports"
• edda request "billing" "[need]: Export BillingPlan type from your crate so I can reference it"
• edda request "api" "[info]: Added new error variant ApiError::RateLimit — you may want to handle it"

If the send fails with "no active session answers to ...", the label is wrong — check edda peers for the live labels. Only pass --force when you are deliberately queuing for a peer that has not started yet.

Step 5: Verify

The send command itself is the verification: a label no active session answers to is an error (with the live labels listed), and a label held by several sessions prints a warning naming how many will see it. A clean exit with Request sent to [<label>] means the request is on the board. Do NOT check edda peers for it — that command lists sessions, not requests.

Registered letter, not doorbell

edda request is a registered letter addressed to a role: it is durable, acknowledged, and survives the peer dying — a replacement session holding the same label receives it on arrival. What it can never do is wake anyone: delivery happens at the peer's next hook event, and an idle session has no next hook event.

If your host has cross-session messaging (a way to send a message that starts the peer's next turn), ring after sending: fixate first (edda request), then send a short host message that only points at it ("coordination request pending — run edda coord"). Letter first, bell second — the letter is the truth, the bell is latency.

Answering requests addressed to you

Requests you receive stay pending until you acknowledge them — being shown the message does not clear it, and the sender has no other signal that it landed. Once you have acted on a peer's request:

edda request-ack "<their-label>"

This retires only what is outstanding now, so a later message from that same peer still reaches you.

Output Format

Present findings:

## Coordination Request

### Changes Detected
- <file>: <what changed (added/modified/removed public API)>

### Affected Peers
- [<label>]: <why affected, what they need to do>

### Requests Sent
- To <label>: <message>

### No Action Needed
- <peers whose scope is not affected by your changes>
