Write a template playbook
A playbook is one markdown file under references/agent-templates/<key>.md in the
build-an-agent skill. The builder agent reads the one that matches the user's ask, then follows
it to configure that specific agent. Your job: encode the use-case thinking so a Sonnet-class
model can execute it. You get one inventory row as input (name, one-line pitch, integrations,
trigger). Turn it into a spec-conforming playbook.
Keep each playbook 1 to 2 KB. An over-comprehensive playbook hurts: the agent cannot extract what is relevant. Write a coherent, moderately detailed unit with a working instructions template.
The skeleton
Fill this in. Omit any section the use case does not need (a no-tool template drops Explore and Connections; a no-trigger template drops the trigger half of Verify).
# <Template name> playbook
## Match
One line: when this playbook applies. The card key plus the shape of the ask, including
free-text asks that match no card.
## Required context (ask via one request_input form)
- <field>: why the agent cannot proceed without it. When the agent can propose a value, set
it as the field's `default` (prefilled, one-click acceptable); no default otherwise. [required]
Only fields the agent genuinely cannot proceed without. One to four. Secrets never go here.
## Researchable context (do not ask; figure it out and state the assumption)
- <field>: what the agent looks up, and what it assumes when the lookup is inconclusive. Never
a question and never an enum. The platform prompt forbids asking for a detail the agent can
look up or default, so this section names the lookup and the fallback assumption instead.
## Explore first (read before proposing)
- Which read tools to discover_tools and wire.
- One test_run passing the uncommitted tools in delta.set.parameters.agent.tools (the FULL
tools list), to see the real repo or workspace. Show the user a concrete example before
committing the full setup.
## Defaults / priors table (situation to proposed setup)
| Situation | Trigger | Tools | Behavior default |
|---|---|---|---|
| <situation> | <trigger> | <reads> + <write> | <what it does> |
## Connections
Which integrations must be ready. If missing, request_connection and stop. List the
tool-agnostic alternatives (Notion OR Confluence OR Google Drive).
## Instructions template (what to commit)
The numbered per-run procedure for instructions.agents_md: exact tools in order, pinned ids,
ending on the terminal action. Include the output-format shape.
## Verify
1. test_run with a blunt test message; read the verdict and the tools line, not a 200.
2. If a trigger: fire an artificial test message first; then ask the user to run the real
trigger test (Lightning "Test event" for a subscription, Play "Run" for a schedule).
## Closing report
What the agent became, what is connected, what is scheduled, what you verified, what still
needs the user.
Every section maps to the build loop: Match to step one, Required and Researchable to
request_input, Explore to discover_tools plus test_run, Defaults to the proposal,
Connections to request_connection, Instructions to commit_revision, Verify to test_run
and the trigger test, Report to the final step.
Three platform facts authors get wrong
These are counterintuitive and every first draft gets them backwards. State them correctly.
request_inputHAS a realdefaultfield (#5190, shipped) — use it. A field'sdefaultprefills the form so the user can accept every proposal in one click; set one whenever the agent can propose a value. Rules: the default must match the field type (array of strings on a multi-select); an empty default (""/[]) means "no proposal" and is stripped; date/date-time fields ignore defaults — do not set them there. For a researchable choice, include a "Figure it out, use your best judgment" enum option and set it as thedefault. Enum options are SUGGESTIONS: every enum renders a built-in "Other…" free-text escape hatch, so keep lists short and likely, not exhaustive. Multi-pick questions use{type: "array", items: {type: "string", enum: [...]}}; options needing a sentence of explanation useoneOf: [{const, title, description}], which renders as selectable choice cards. Forms with several questions can set"x-ag-stepper": trueon requestedSchema (one question at a time + review) — the tool description teaches this; playbooks do not re-state it.test_runexercises uncommitted tools through its in-memory delta (delta.set.parameters.agent.toolscarries the FULL tools list, lists replace wholesale). So exploration does NOT require commit-and-stop-turn. Explore the real repo or workspace with new tools before committing anything. Commit-and-stop is only a fallback for when the flow cannot carry the delta.- The trigger-test affordance is Lightning "Test event" (event subscriptions) or Play "Run" (schedules). It is never a flask icon. The flask is for Evaluations. Write the correct copy in every Verify section.
What a playbook NEVER contains
Add what the model lacks for this use case; omit what it already knows. Do not put in a playbook:
- The generic build loop (discover, commit, test). It lives in the build-an-agent skill body.
- The config schema (tool entries, the fixed
llm/harness/runnerblock). It lives in the skill body andreferences/config-schema.md. - Tool wire shapes or cron rules. Those live in the skill body and its other references.
A playbook that re-teaches these wastes the 1-2 KB budget and drifts from the source of truth.
