Cargo Cdk

Cargo CDK — declarative workspace-as-code

Use this skill to define a Cargo workspace in TypeScript (define* builders from @cargo-ai/cdk) and reconcile it to live infrastructure with cargo-ai cdk deploy. It is the declarative counterpart to the imperative capability skills: instead of running one CLI command per resource, you write the whole graph once and deploy it repeatably, with a committed cargo.state.json linking your code to what Cargo created.

Bootstrap

Already signed in (cargo-ai whoami returns a workspace)? Skip to the next section.

npm install -g @cargo-ai/cli            # no global install? prefix every command with `npx @cargo-ai/cli`
cargo-ai login --email you@company.com  # emailed code, no browser; creates the account on first use
                                        # alternatives: --oauth (browser) · --token <api-token> (CI)
cargo-ai whoami                         # confirm the active workspace before any write
cargo-ai cdk --help                     # `unknown command` = CLI too old; reinstall @cargo-ai/cli@latest

Two CDK-specific extras: the project needs @cargo-ai/cdk as a dependency for the define* builders you import (cargo-ai cdk init scaffolds a package.json with it — then npm install), and the cargo-ai cdk domain ships with the CLI itself.

Every command prints JSON to stdout; failures exit non-zero with {"errorMessage": "..."}. Anything that creates a run or a batch is async — pass --wait-until-finished or poll the matching get. When the full skill bundle is installed, ../cargo/references/prerequisites.md adds the CLI version pin, token scopes, and the admin-only surface.

1) What this skill governs

• Authoring every Cargo resource with a define* builder that returns a handle; wiring resources by passing handles to each other (the dependency graph is your variable graph).
• Deploying the graph: plan (offline diff) → deploy (create/update, write state) → destroy (tear down). Plus drift (refresh), adoption (import), and recovery (rollback).
• Typing the config against your workspace's real integration schemas (cargo-ai cdk types).

The CDK spans every resource kind — so it overlaps every imperative capability skill (cargo-connection, cargo-storage, cargo-ai, cargo-orchestration, cargo-content, cargo-hosting, …). Which to reach for is the first decision:

2) CDK or the CLI? — the routing decision

Declarative (this skill) vs imperative (a capability skill).

Use the CDK when the user is managing resources as an artifact:

• "Set up / stand up / bootstrap a whole workspace (as code / from a template)."
• "Make this reproducible / version-controlled / in git / repeatable across environments (dev → prod)."
• "Deploy these connectors + models + agents together" (a multi-resource graph wired by dependency).
• Anything that should be re-runnable and diffable, where losing the definition would be a problem.

Use the matching capability skill (imperative cargo-ai <domain>) when the user is doing a one-off operation or exploring:

• "Create one connector", "add a column to this model", "list connectors", "run this workflow", "query storage", "read this agent's memory."
• Any read, ad-hoc query, or single mutation that doesn't need to live in code.

When unsure, ask whether the result should be committed and re-deployable. If yes → CDK. If it's a quick action or a read → the capability skill (see the cargo router to pick the right domain).

3) The lifecycle

cargo-ai cdk init <dir>     scaffold a project from a template (blank | full)
        │
cargo-ai cdk types          generate per-workspace types for typed config (optional)
        │
   (author define* files)   importing a .ts file IS registration — no manifest
        │
cargo-ai cdk plan           offline: compile the graph, diff against cargo.state.json
        │
cargo-ai cdk deploy         create/update resources in dependency order, write state
        │
cargo-ai cdk destroy        tear down resources recorded in state

cdk plan says what resources change; it doesn't show what a play does. For a definePlay / defineTool graph past three nodes, present a Mermaid flowchart of the node graph alongside the plan — routing, fallbacks, and which nodes bill on every scheduled run are what the reviewer is approving. Generate it from the deployed release after the first deploy, or from the node array while authoring: ../cargo-orchestration/references/node-diagram.md.

Side branches: cargo-ai cdk refresh (read-only drift report) · deploy --refresh (re-apply code over out-of-band edits) · deploy --prune (delete resources removed from code) · cargo-ai cdk import <id> <uuid> (bind an existing live resource into state) · cargo-ai cdk rollback (restore the pre-deploy state snapshot).

4) Documentation hierarchy

• Level 1 — SKILL.md (this file): the decision model, lifecycle, critical rules, and routing.
• Level 2 — Guides: guides/authoring-resources.md, guides/deploy-and-state.md, guides/typed-config.md.
• Level 2.5 — Recipes: recipes/*.md — step-by-step playbooks to follow as your execution plan.
• References — references/resources.md (the full builder catalog), references/commands.md (every cargo-ai cdk subcommand + flags), references/troubleshooting.md, and references/examples/full-workspace.md.

5) Read behavior — match the task to a doc and READ IT

Cookbooks — check the menu before authoring a known outcome from scratch

getcargohq/gtm-skills holds, beside its one-off skills, cookbooks: skills that carry worked CDK resources, the same job as a deployed pipeline that keeps producing the result (TAM building, account scoring, contact sourcing, routing engine, AI SDR, rep cockpit, …). Every folder is self-contained: its own models, connectors and folders, no shared foundation, no requires graph.

The menu is local: references/cookbooks.md. Read it before authoring a common GTM outcome from scratch. It is generated from gtm-skills' catalog.json, so it cannot drift.

A cookbook is a worked example, not a template to fill in. Each one declares in its SKILL.md what may be reshaped, what must hold or it stops working, and what has to be answered either way, and it carries its own procedure. cdk add is the copy step in that procedure:

cargo-ai cdk add cookbook/tam-building               # inside a CDK project
cargo-ai cdk init my-project --cookbook tam-building # no project yet: both at once

That writes the resources to infra/tam-building/ and the procedure to .claude/skills/tam-building/, skipping any file it would overwrite. Then start the skill at its Adapt section — its opening steps are written for someone who found the folder on GitHub and still has to place it, so following them from the top scaffolds a second project and copies the folder in again.

What is left after the copy is the part only you can do: reconcile it with what is already declared, adapt the copied files in place to the project's real shape (do not regenerate them from the skill's prose — the safety lives in the TypeScript), plan and stop, deploy on a yes, walk its Done when.

If you are mid-task and the skill is not in this session, npx skills add getcargohq/gtm-skills/<slug> fetches the procedure alone and you can read .agents/skills/<slug>/SKILL.md directly; no reload needed. To read one without installing, npx skills use getcargohq/gtm-skills@<slug> prints it. Neither brings the CDK resources — for those you still want cdk add.

Routing rule: one-off versus standing. A user who wants the list today wants cargo-gtm (or gtm-skills' one-off build-tam-list); a user who wants a pipeline that keeps producing it wants tam-building. The same words describe both ("build our TAM"), so listen for whether the result is meant to keep arriving. A cookbook matches → install it and follow it. No match → author from the recipes below.

Never cargo-ai cdk init --force into a directory that is not empty. It replaces the project's package.json and reverts adapted code, while cargo.state.json survives, so the next plan diffs a live workspace against code nobody wrote. Copy the skill folder in as a sibling instead.

Caveat: the examples typecheck, but they are not yet deploy-verified against a live workspace, and every one is to-be-approved. Treat each skill's Done when as the acceptance test, and always review cargo-ai cdk plan before deploying.

Recipes — follow step-by-step when one matches

6) Critical rules

• Commit cargo.state.json. It is the link from your code to the resources Cargo created — and the only handle on a deployed play, agent, or alert (they have no slug). Lose it and those resources orphan; recover a link with cargo-ai cdk import. It records only {hash, uuid, outputs} — never secret values. Git-ignore the working files (cdk init scaffolds this):

  .cargo-ai/
  cargo.state.lock
  cargo.state.bak.json
  cargo.state.audit.jsonl
  

• Secrets: wire credentials with secret("ENV_VAR") (often secret("HUBSPOT_API_KEY")). The value is read from the environment at deploy time, kept out of the content hash and out of state, so rotating a token doesn't read as drift. Export the env var before deploying — a missing one fails the deploy with an unresolved ${ENV_VAR} placeholder.
• Wire by handle, never by .uuid. Pass a define* handle directly (dataset: hubspot, tools: [enrich]), or xxRef("uuid") for a resource you didn't define in code (connectorRef, modelRef, folderRef, toolRef, agentRef, …). Where a reference needs per-call options, wrap it as { ref, …options } (e.g. models: [{ ref: contacts, readOnly: true }]).
• Run cargo-ai cdk types after workspace integrations change — it regenerates .cargo-ai/ so defineConnector/defineModel config (and integrations.* in workflow bodies) type-check against the real schemas. Typing is a bonus, never a gate: deploy works without it.
• Run cdk commands from the project root. npx/cargo-ai resolve from the nearest package.json; run elsewhere and .cargo-ai/ and cargo.state.json land in the wrong directory. Use --dir <path> to be explicit.
• --yes in CI. deploy and destroy prompt for confirmation; non-interactive runs must pass --yes.
• A definePlay/defineTool graph with paid nodes gets a sample run before it goes wide. Deploying is not running, but the first thing that runs a deployed play is usually a batch over the whole segment — and a scheduled play re-bills every node on every run. Before enrolling everything (or enabling a schedule), run the deployed workflow on 10–20 records — cargo-ai orchestration batch create --data '{"kind":"filter","modelUuid":"…","filter":…,"limit":15}', or batch create --file ./plays/x.ts to test-run the module without deploying — then ask the user to approve the full enrollment with the record count and credit estimate. Read the provider's playbook (../cargo-gtm/provider-playbooks/<slug>.md, esp. its Recurring use section) and the gate in ../cargo-gtm/references/cost-discipline.md.
• A defineAlert whose actions call paid nodes re-bills on every breach. An alert's actions fire as real runs, so a badly-sized threshold on a tight schedule can breach — and bill — every tick. Size the threshold with cargo-ai observability alert preview before deploying, prefer cheap notification actions (an agent that posts, a connector notification) over anything that fans out, and apply the same cost gate above when an action calls a credits-based provider. Scope/threshold and firing semantics: ../cargo-observability/SKILL.md.
• defineMailbox bills monthly, and defineDomain rewrites a DNS zone. A mailbox is 100–160 credits per month for as long as it exists (cargo-ai mailboxManagement pricing get for live figures), so a + create mailbox:… line in the plan is a recurring charge the user approves, not a one-off. Its domain, username and type are create-only — changing any of them is destroy + recreate, i.e. a brand-new inbox back at the bottom of a 45-day warm-up ramp. The deploy polls refreshStatus for up to 5 minutes waiting for active. On defineDomain, dnsRecords is the whole zone, not a patch: declaring it replaces every live record (including the ones the registrar wrote at purchase), and omitting it leaves the zone untouched. Use adopt: true for a domain or mailbox bought in the UI. Ramp, suppression and sending: ../cargo-mailbox-management/SKILL.md.
• Route CDK-managed resources into a clearly-labelled folder. Set folder: on each builder so everything CDK owns lands in a dedicated folder whose name signals "owned by code — don't hand-edit" to anyone in the UI (manual UI edits read back as drift on the next plan). Folders are per-kind, so give each kind its own but share one short, recognizable prefix — recommended: 🔒 CDK (e.g. 🔒 CDK Models, 🔒 CDK Agents). Keep names short (long labels truncate in the folder tree); the lock emoji is the "don't touch" cue. See guides/authoring-resources.md.

Help

• cargo-ai cdk --help and cargo-ai cdk <subcommand> --help for the live flag surface.
• When a documented command/flag/response doesn't match what you observe, file a report: cargo-ai workspaceManagement report create (see ../cargo-workspace-management/SKILL.md).
