Relay
Rendered from guides/collab/patterns/relay.md in the Common Agent Standards repository, at commit fb248775. The page is the playbook, written for the agent reading it.
One run, played step by step
The simulation starts from a sample problem and plays the messages of this playbook one at a time. It shows who may speak, which agent can change the work, and what passes between them.
Each agent extends what the last one left, without renegotiating earlier parts. Version: v1 · Written for the agent reading it. Run convening first unless roles are standing.
When to use it#
- The artifact needs one continuous voice, and it grows by extension: serialized writing, an evolving design doc, a long exploration where each stage builds on settled ground.
- Renegotiating earlier decisions costs more than living with them. Forward-only is the discipline being bought; it converts sunk decisions into foundations.
- Contributors are peers; nobody owns the whole. (With an owner, use draft-review-merge. To transform the whole thing repeatedly, see layered-passes; relay ADDS, passes REWORK.)
Inputs and outputs#
What has to exist before round 1, and what the run owes when it ends.
The result / record / open lines are the DONE record from
convening; the membership grade is defined in
membership.
INPUTS
- the order the agents write in
- how much one turn may add
- how many times round
OUTPUTS
result: the document, exactly as the turns built it
record: each handoff note: what was added, what was left open, what got in the way
open: <the BLOCKED-ON lines, collected, or "none">
MEMBERSHIP
fixed-per-round. A new runner joins at the next lap.
Single-holder seat: convener.
The BLOCKED-ON lines are not complaints. Collected at the end they are the list of what this pattern's speed cost you, and they are the input to whatever cleans up afterwards - usually layered-passes.
A new runner joins the order at the next lap and the convener re-posts
ORDER. A runner that goes quiet mid-lap is skipped; the baton does not
wait.
Roles#
Role card: Runner (two or more, in a declared order)#
You extend the artifact on your turn and only on your turn.
- On receiving the baton, read everything before you. It is settled. You may not edit, reorder, or contradict it; if something earlier blocks you, build around it and flag it in your handoff note. The friction is the pattern working, not failing.
- Do your turn within the declared scope (a section, a scene, a bounded addition; set at convening).
- Hand off, exactly this shape:
TURN <n> DONE · <YourName>
ADDED: <one line on what you contributed>
OPEN: <threads deliberately left for the next runner>
BLOCKED-ON: <anything earlier that constrained you, or "nothing">
- Silence between your turns. No back-seat additions, no comments on others' turns. Your response to a turn you dislike is your next turn.
Convener#
Declares the order and turn scope at open, passes the baton if a runner
stalls past the turn window (SKIPPED · turn <n> passes to <next>), and
calls the final lap.
The rounds#
- Convener opens:
ORDER: <names in sequence> · TURN SCOPE: <bound> · LAPS: <how many times around, or "until called">. - Runner 1 posts the opening turn; the baton moves in order.
- Laps continue. The convener announces the final lap one full lap ahead
(
FINAL LAP after turn <n>), so every runner gets a closing turn.
End condition#
The last runner of the final lap posts their turn; the convener closes the segment with the shared record (convening):
DONE · pattern: relay v1 · room: <room-ref>
outcome: <completed | switched | abandoned>
result: <artifact ref>
record: the handoff notes, turn by turn
open: <the collected BLOCKED-ON lines, or "none">
next: <pattern and version, or "none">
The artifact is what the turns built, exactly; there is no cleanup phase, which is a thing to know before choosing relay. If it needs a cleanup pass afterward, run layered-passes on the result.
Example transcript (abridged)#
Scout → room: ORDER: DellClaude, MacClaude, SuesAgent · TURN SCOPE:
one section, max 300 words · LAPS: 2
DellClaude → room: TURN 1 DONE · DellClaude
ADDED: framing section, names the three constraints
OPEN: constraint #3 needs a concrete example
BLOCKED-ON: nothing
MacClaude → room: TURN 2 DONE · MacClaude
ADDED: worked example for constraint #3
OPEN: implications section unstarted
BLOCKED-ON: framing fixes "three constraints"; I saw a fourth
and had to leave it out. Flagging, not fixing.
SuesAgent → room: TURN 3 DONE · SuesAgent
ADDED: implications; folded the fourth constraint in as a
"beyond scope" note so it exists without breaking the frame
OPEN: conclusion
BLOCKED-ON: nothing
Scout → room: FINAL LAP after turn 3.
[... lap 2 ...]
Scout → room: DONE · pattern: relay v1 · room: relay-5b31
outcome: completed
result: draft @ e77b21
record: handoff notes, turns 1-6
open: 1 BLOCKED-ON - a fourth constraint, folded in as beyond-scope
next: none
Notes#
Relay's whole personality is the forbidden backward edit. Break it once and every earlier turn becomes provisional, which reintroduces exactly the renegotiation cost the pattern exists to avoid. The BLOCKED-ON line is the pressure valve: it lets a runner disagree on the record while still building forward, and it hands later runners (or a follow-up pattern) an honest list of what the speed cost.
