What Is A Pod

A pod is one team's operating system: a shared workspace inside an organization that holds everything one use case needs — tables and files (data, with documents auto-indexed for built-in RAG), functions, agents, workflows, schedules, and connectors (automation), and apps and surfaces (interfaces) — under one permission boundary. Two rules run through all of it: every workload starts with zero access and is granted resources explicitly by name, and a workload acts under the delegated identity of the user who invoked it (so RLS and the personal /me area resolve to that user). Good pod scope = one team, one operating loop, one coherent data model.

Read references/pod-model.md first. It is the canonical model every other doc grounds in — identity & permissions, the data/automation/interface layers, how the resources interact, and how a pod is authored. This file is the build entry point on top of it.

The Resources

Choosing among them — six heuristics (full text in references/pod-model.md → "Choosing a primitive"; pod-design.md turns them into decision tables):

1. One step, one agent. One agent returning rich output_schema beats an agent→agent chain; split only for orthogonal judgments.
2. Workflow = checkpoints + humans. Reach for a workflow when people approve, are assigned steps, or watch progress — not for a lone call.
3. Surface = a human is talking. A chat-platform conversation is a surface; a system event driving unattended work is a schedule → workflow/agent.
4. Events choreograph workloads. A table write or connector trigger starts the next workload (server-side); an app stays live via watchChanges (client-side).
5. Occam's razor. Build the fewest agents and nodes that satisfy the use case.
6. Reach for the most direct primitive. A single record write is a direct records-API call, not a function; a bare agent is called directly or granted as a tool — never wrapped. A function earns its place only for deterministic multi-step work (coordinated writes, write + compute, or a connector call).

The Build Loop

Pods are built as local directory bundles and imported with upsert. This is the primary path — inline lemma <resource> create --data ... is only for quick experiments.

Scaffold, don't hand-write. lemma <resource> init writes a near-runnable, commented bundle file (JSONC — // and /* */ comments and trailing commas are allowed) with the right shape, folder==name wiring, and the backend defaults (visibility, RLS, function headers). Edit it, then import.

lemma pod init my-pod                  # whole starter pod on disk (pod.json + table + agent + AGENTS.md)
# or scaffold into an existing bundle (auto-finds pod.json upward):
lemma tables init tickets [--shared]   # tables/tickets/tickets.json  (--shared = enable_rls:false)
lemma functions init score_ticket      # functions/score_ticket/{score_ticket.json,code.py} with headers
lemma agents init triage [--runtime ID] # agents/triage/{triage.json,instruction.md}
lemma workflows init intake            # a valid FORM->END graph to extend
lemma schedules init nightly           # schedules/nightly/nightly.json
lemma surfaces init slack              # surfaces/slack/slack.json

lemma agents grant triage tickets:read,write /knowledge:read app:gmail:use agent:helper:execute function:score_ticket:execute
#   ^ merges into permissions.grants in place (keeps your JSONC comments): name:perms (table) | /path:perms (folder) | app:name:use | agent:name:execute | function:name:execute
lemma agents schema                    # or `lemma schema agent` — print the example/shape for a resource type

lemma pods create my-pod --with-starter   # create the pod AND scaffold+import a starter in one shot

By hand, or after scaffolding — the bundle is always the source of truth:

lemma pods create my-pod --org <org> --description "..."   # import never creates the pod shell

mkdir my-pod && cd my-pod                                  # author the bundle locally
# pod.json + one folder per resource (see layout below)

lemma pods import ./my-pod --dry-run                       # validate, fix errors
lemma pods import ./my-pod                                 # upsert by resource name (default)
lemma pods import ./my-pod/functions/score_ticket          # partial imports work too
lemma pods doctor my-pod                                   # check grants/targets/surfaces wiring

lemma functions run score_ticket --data '{"title":"test"}' # test each layer
lemma workflows run intake --data '{"id":"REQ-1"}'         # waits for completion by default
lemma agents chat triage-agent "Classify this ticket"

# edit files -> re-import -> re-test. Export an existing pod for a baseline (or a template):
lemma pods export ./bundles --force [--as-template]

Bundle layout (folder name must equal the resource's name):

my-pod/
  pod.json
  tables/tickets/tickets.json
  functions/score_ticket/score_ticket.json    + code.py        (JSON carries permissions.grants)
  agents/triage-agent/triage-agent.json       + instruction.md (JSON carries permissions.grants)
  workflows/intake/intake.json
  schedules/nightly/nightly.json
  surfaces/slack/slack.json
  apps/ops-app/ops-app.json                + source/
  files/knowledge/.folder.json
  seed/seed.sh                                 # sample data so the pod demos itself (not imported — run after)
  payloads/                                    # test fixtures, not a pod resource
  README.md                                    # operator setup + verification runbook

Build order follows dependencies: tables → files → functions → agents → workflows → schedules → connectors/surfaces → app → seed. Verify each layer with realistic data before adding the next.

Build for the hero moment, not just for correctness. A pod that imports cleanly and passes its tests can still be plumbing nobody wants to open. Before building, name the one screenshottable "oh" — the agent doing real work on its own, behind an interface someone adopts (see references/pod-design.md). The app (or surface) is usually the product — design it like the thing people live in, not an afterthought tacked on last. And seed the pod so it demos itself: a seed/seed.sh of sample rows, files, and one completed run, so opening the app shows the hero moment immediately instead of an empty state. (Records and file contents don't round-trip through import — the seed script is how they land; record it in the README.)

Three rules that bite everyone:

1. Zero access by default, and no destructive power without a grant or approval. Agents and functions are created with NO access to anything — not tables, not files/folders, not connectors. Every resource they touch must be granted explicitly, either via permissions.grants in their bundle JSON (exported automatically, replaced on import) or lemma functions|agents permissions replace <name> --file grants.json. A named workload's grant is standalone authority (grant-first). MISSING_WORKLOAD_RESOURCE_GRANT at runtime means a grant is missing; DESTRUCTIVE_ACTION_REQUIRES_APPROVAL means a delete/manage action needs either an explicit destructive grant or a user's session approval. Full 403 decoder + the complete model in references/authorization-model.md.
2. Not everything bundles. File contents and connectors (auth configs, accounts) are not part of import/export — set those up with CLI commands and record the steps in the pod's README. Surfaces and workload permissions do round-trip in bundles.
3. Leave a runbook. Every production-quality bundle should include a README with: purpose, required CLI context, non-bundled setup steps, required uploaded files, connector auth configs/accounts, verification payloads, and the final end-to-end smoke test.
