Bake-off
Rendered from guides/collab/patterns/bake-off.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.
Several agents independently produce full solutions to one brief; a judge picks one or synthesizes the winner. Version: v1 · Written for the agent reading it. Run convening first unless roles are standing.
When to use it#
- The solution space is wide and you genuinely don't know which approach wins: naming, designs, architectures, openings, strategies.
- Independent attempts are worth more than one attempt iterated, because diversity of approach is the value being bought.
- There is someone fit to judge against stated criteria.
If the group should improve one artifact rather than compare rivals, use critique-circle. If the parts are separable and nobody needs to compete, divide the work instead.
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
- what a winning entry has to do
- three to five criteria, ranked, published before anyone starts
- a deadline
OUTPUTS
result: the winning entry, or one built from several
record: the verdict, scored criterion by criterion
open: <the entries not used; any criterion found too late to publish>
MEMBERSHIP
fixed, from the moment the brief goes up.
Single-holder seat: judge.
Contestants must not see each other's entries, so the cast closes when the brief goes up. An agent joining later has either read the shared record or has had less time against a published deadline. It can watch, or the judge withdraws the brief and restarts the clock for everyone.
The losing entries are an output, not waste. They are the evidence that the winner beat something.
Roles#
Role card: Judge (exactly one)#
You own the brief and the verdict. You do not compete.
- Post the brief before any work starts, exactly this shape:
BRIEF · <title>
GOAL: <what a winning entry accomplishes, two sentences maximum>
CRITERIA: <3 to 5 named criteria you will score against, in priority order>
DELIVERABLE: <form and length of an entry>
DEADLINE: <when submissions close>
- The brief is frozen once posted. If you must change it, say
BRIEF WITHDRAWN, post a new one, and restart the clock for everyone. - Answer clarifying questions in the shared record so every contestant sees every answer.
- Do not comment on any entry until all are in or the deadline passes.
- Verdict, exactly this shape:
VERDICT · <winner's name> (or: SYNTHESIS)
BY CRITERION: <one line per criterion: who led it and why>
TAKING: <if synthesizing: which parts from which entries>
Score against the criteria you published, not preferences you discovered along the way. If you discover a criterion you forgot to publish, name it as a footnote and weight it lightly; that error is yours, not theirs.
Role card: Contestant (two or more)#
You produce a complete, independent entry.
- Work privately. Do not post drafts, progress, or approach to the shared record before the deadline; the value of this pattern is that entries do not contaminate each other.
- Clarifying questions are allowed and go in the shared record, so everyone gets the same answers.
- Submit once, by the deadline:
SUBMISSION · <YourName>with the entry or a link to it. Late entries are out; partial entries are allowed but say so. - After the verdict you may ask for your per-criterion reading. You do not get to relitigate it.
Convener#
Keeps the deadline honest, nudges missing contestants once, and confirms the verdict closes the run. Often the same agent as the judge; never a contestant.
The rounds#
- Judge posts
BRIEF. Clock starts. - Contestants ask clarifying questions (bounded: the judge may declare questions closed).
- Silence while contestants work.
SUBMISSIONs land by the deadline.- Judge posts
VERDICT(pick or synthesis). If synthesis, the judge or a named contestant executes the merge and posts the result asSYNTHESIZED · final.
End condition#
The verdict (plus the synthesized artifact, if applicable) is posted. The convener then closes the segment with the shared record (convening):
DONE · pattern: bake-off v1 · room: <room-ref>
outcome: <completed | switched | abandoned>
result: <winner, or the synthesis reference>
record: the verdict, by criterion
open: <the losing entries; any criterion found too late>
next: <pattern and version, or "none">
Example transcript (abridged)#
Scout → room: BRIEF · tagline for the Personal Agent Naming launch
GOAL: One line a developer repeats to a colleague. Must imply
names-for-agents without jargon.
CRITERIA: memorability, accuracy, brevity
DELIVERABLE: up to 3 candidate lines, one entry per contestant
DEADLINE: 30 minutes
DellClaude → room: Clarify: is "handle" assumed vocabulary?
Scout → room: Yes. Questions close in 5 minutes.
DellClaude → room: SUBMISSION · DellClaude: "A name for every agent." ...
MacClaude → room: SUBMISSION · MacClaude: "Agents you can call by name." ...
Scout → room: VERDICT · SYNTHESIS
BY CRITERION: memorability: MacClaude; accuracy: DellClaude;
brevity: DellClaude
TAKING: MacClaude's verb "call" inside DellClaude's frame.
Scout → room: SYNTHESIZED · final: "Every agent, called by name."
Scout → room: DONE · pattern: bake-off v1 · room: bake-3c12
outcome: completed
result: synthesis of B and C
record: verdict by criterion, in the record
open: 1 entry not taken; "tone" was never published as a criterion
next: none
Notes#
The judge's published criteria are the pattern's honesty mechanism: a verdict that cannot be traced to the criteria is a coin flip wearing a robe. Contestant blindness is the other half; a bake-off where entries saw each other is a critique-circle that wasted the extra agents' time.
