Pod + Workflow Tutorial

Pod and Workflow are meant to work together, but they solve different parts of the problem:

• Pod runs durable workers, records a ledger, keeps logs and artifacts, and exposes status/restart/stop controls.
• Workflow describes orchestration: phases, branches, reducers, loops, and agent leaves that can dispatch through the Pod/sub-agent runtime.

Default product path: ask in natural language. Operate can use direct tools under the active posture, and prefers one or more background Pod workers when work is independent, parallel, isolated, or long-running. Background work keeps the composer available for more messages. It chooses Workflow only when ordered phases, gates, shared budgets, or deterministic fan-in add real value; you do not need to write workflow files for ordinary multi-agent work. Details: Automatic Workflows.

This tutorial covers the manual Pod task-spec / checked-in Workflow path for operators who want durable host workers and reviewable specs. A one-sentence request should still not silently generate tasks.json; worker cards and permission posture make dispatch visible without exposing authoring mechanics.

The examples use the canonical codewhale pod and /pod spellings. Existing codewhale fleet and /fleet commands remain compatibility aliases, while on-disk paths, config keys, and the Workflow --fleet flag retain fleet.

1. Prepare The Workspace

Run Pod from the workspace you want workers to inspect or modify:

codewhale pod init

This creates the workspace ledger at .codewhale/fleet.jsonl. Worker logs and bounded artifacts live under .codewhale/fleet/; host adapter logs live under .codewhale/fleet-host/.

If you want named reusable workers, open the TUI and run:

/pod setup

Pick a role, choose whether that profile inherits the operator route or pins a specific provider/model, choose where the profile lives (This project → .codewhale/agents/<role>.toml, or Personal → $CODEWHALE_HOME/agents/<role>.toml, available across repositories while a same-id project profile remains the higher-priority override), then review the exact file, permissions/tools/route posture, and save. The save control names its effect ("Save to this project" / "Save as Personal profile"), and replacing an existing file always asks for a second confirmation. Pod task specs can reference either resolved profile with worker.agent_profile or the shorter worker.profile alias.

This makes the Pod definition cross-repository, not the authority of one running session. For a multi-repository operation, launch Codewhale from a shared parent workspace. Profile availability does not grant filesystem access; the session's workspace, explicit trusted paths, trust mode, and permission posture remain authoritative.

2. Write A Pod Task Spec

codewhale pod run accepts JSON or TOML. The checked-in docs/examples/fleet-dogfood.toml file is the realistic manual smoke example; the JSON below shows the same authoring shape with one read-only reviewer and one bounded docs-note worker. The live Runtime policy controls secrets and trust; Pod identity carries neither.

      "scorer": {
        "kind": "manual"
      }
    }
  ]
}

Save it as tasks.json.

Common task fields:

Field	Purpose
id, name	Stable task identity and display name.
objective, instructions	The worker goal and exact operating instructions.
worker.role	Built-in or custom role intent, such as reviewer, builder, read-only, or smoke-runner.
worker.profile / worker.agent_profile	Saved Pod roster profile resolved from project .codewhale/agents/, personal $CODEWHALE_HOME/agents/, or [fleet.profiles].
worker.tools	Tool names the task expects the worker to use.
worker.model	Preferred explicit model pin. Route resolution still owns provider/model validation.
worker.model_class, worker.loadout	Compatibility routing hints for older task specs; prefer worker.profile plus saved profile route pins for new specs.
workspace.required_files	Files that must exist before the task starts.
workspace.writable_paths	Paths the task is allowed to write when the effective runtime posture allows writing.
workspace.environment	Required or allowlisted environment variables, by name only.
input_files, context	Extra files and strings to thread into the task prompt.
expected_artifacts	Artifact kinds to expect: log, report, patch, test_result, checkpoint, or receipt.
scorer	Deterministic or manual verification rule.
retry_policy, timeout_seconds, budget	Retry and budget controls.

Do not put security_policy or worker trust_level in a new Pod task spec. Those legacy fields remain readable only for old ledger replay and new-run validation rejects them. Project trust, filesystem/network reach, secrets, approvals, sandboxing, and tool authority are Runtime policy inputs.

3. Start And Monitor Pod

Launch the run:

codewhale pod run tasks.json --max-workers 4

The command prints the run id and worker ids. In another terminal, monitor the ledgered state:

codewhale pod status
codewhale pod inspect <worker-id>
codewhale pod logs <worker-id>
codewhale pod artifacts <worker-id>

Use typed controls when a worker needs intervention:

codewhale pod interrupt <worker-id>
codewhale pod restart <worker-id>
codewhale pod resume <run-id>
codewhale pod stop --all

resume is for restart recovery after a manager exit, laptop sleep, or stale lease. It replays the ledger and reconciles stale work without creating a new run.

4. Author A Workflow

Workflow source is declarative JavaScript or TypeScript that lowers to typed Rust WorkflowSpec. It is not a general JavaScript runtime: imports, process access, filesystem reads/writes, network calls, eval, async, and await are rejected.

Create a checked-in file such as workflows/docs_readiness.workflow.js. The repo also includes workflows/issue_audit.workflow.js as a maintained example.

export default workflow({
  "id": "docs-readiness",
  "goal": "Inspect Pod and Workflow docs, then synthesize a readiness note",
  "nodes": [
    {
      "branch": {
        "id": "parallel-docs-audit",
        "parallel": true,
        "children": [
          {
            "agent": {
              "id": "fleet-docs",
              "prompt": "Inspect docs/FLEET.md for command and task-spec coverage.",
              "agent_type": "review",
              "mode": "read_only",
              "profile": "reviewer",
              "file_scope": ["docs/FLEET.md"]
            }
          },
          {
            "agent": {
              "id": "workflow-docs",
              "prompt": "Inspect docs/WORKFLOW_AUTHORING.md for Workflow authoring coverage.",
              "agent_type": "review",
              "mode": "read_only",
              "profile": "reviewer",
              "file_scope": ["docs/WORKFLOW_AUTHORING.md"]
            }
          }
        ]
      }
    },
    {
      "reduce": {
        "id": "readiness-summary",
        "inputs": ["fleet-docs", "workflow-docs"],
        "prompt": "Summarize the exact docs gaps and the safest next edit."
      }
    }
  ]
});

Current Workflow node wrappers are agent, branch, sequence, reduce, teacher_review, loop_until, cond, and expand. agent.profile names a Pod roster profile; explicit agent fields override profile defaults.

The model-facing workflow tool can start, run, inspect, or cancel a workflow from inline source or a source_path. When Codewhale uses this path, ask it to show the plan first if the workflow will launch multiple workers or touch files.

5. Natural Language Intake

A good prompt today is:

Draft a Pod task spec for this goal, but do not run it yet.
Show the proposed tasks, worker profiles, writable paths, expected artifacts,
scorers, and security policy. Keep secrets disabled unless I explicitly grant
them.

After reviewing the generated spec, save it as tasks.json and run the Pod commands above. For workflows, ask Codewhale to draft a .workflow.js file, show the plan, and use the workflow tool path only after approval.

This review step is intentional. It keeps provider routing, DeepSeek or other model support, writable paths, network access, and secret use explicit before durable workers start.
