description	Router for the Cargo CLI skill bundle — load first for anything Cargo, and whenever a task spans two Cargo domains. Explains what each skill owns, declarative workspace-as-code (cargo-cdk) vs the imperative CLI, the UUID and slug flow between skills, async polling of runs and batches, end-to-end use cases, and the gotchas that fail silently (`conjonction` spelling, run vs batch, model-uuid vs segment-uuid). Triggers: \"set up Cargo\", \"what can Cargo do\", \"which Cargo skill\", \"bootstrap my workspace\", \"I have a Cargo account\", \"cargo-ai …\", or any `cargo-ai` command whose domain you are unsure of. Skip when: the task obviously belongs to one skill — load that skill directly.

Cargo CLI — Skills Overview

This repository contains 19 skills at the repo root: this router (cargo), one onboarding skill (cargo-quickstart), one outcome skill (cargo-gtm), and sixteen capability skills.

• cargo-quickstart — guided first-run demo. Fresh workspace → real deliverable (25 leads for the user's persona, with a cost receipt) in under two minutes, ending by saving the demo as a recurring play. Load for new users, demo/tour requests, or empty workspaces.
• cargo-gtm — application library. The front door for any GTM task ("build a TAM list", "find 5 fintech CTOs", "monitor job changes"). Routes via internal recipes (../cargo-gtm/recipes/*.md) and provider playbooks (../cargo-gtm/provider-playbooks/*.md).
• Capability skills — standard library. One per CLI domain (orchestration, storage, segmentation, connection, AI, content, context, analytics, billing, observability, hosting, cdk, mailbox management, workspace management), plus cargo-diagnostics (cross-domain forensics over runs, batches, and credit spend) and cargo-mcp (the hosted MCP server, the one surface that is not the CLI). Loaded by cargo-gtm, or directly when you need a specific CLI domain.
• cargo-cdk — the declarative one. Where the other capability skills wrap imperative one-off cargo-ai <domain> calls, cargo-cdk defines the whole workspace as code (define* builders + cargo-ai cdk deploy) and reconciles it. It spans every resource type — see "Declarative vs imperative" below to route between it and the imperative skills.

cargo-gtm delegates to capability skills; capability skills never reference cargo-gtm (one-way dependency).

Glossary: See references/glossary.md for term-by-term definitions (UUIDs, slugs, conjonction, run/batch/play/tool, signal/persona/ICP, etc.).

Interaction conventions: See references/interaction.md for the pack-wide defaults on when to stop and ask (plan gate before building, recommended-default choices) and how to present results (narrate, summarize — never dump raw JSON).

Installation

npm install -g @cargo-ai/cli

# Recommended: emailed code, no browser at any point.
# Creates the account and a workspace on first use — there is no separate sign-up step.
cargo-ai login --email [email protected]            # sends the code, then exits
cargo-ai login --email [email protected] --code 123456

# Alternatives
cargo-ai login --oauth                            # browser sign-in (OAuth device flow)
cargo-ai login --token <your-api-token>           # existing workspace-scoped API token (CI)

# Optional: pick the workspace at login instead of being prompted
cargo-ai login --email [email protected] --workspace-name "Acme GTM"

# Verify
cargo-ai whoami

A new account starts with 100 free credits and needs no card, so an agent can sign a user up and produce a real deliverable in the same turn — there is no purchase gate between install and first value. Useful anchors for what that buys: ~5,000 leads sourced (salesNavigator.searchLeads, 0.02/record), ~1,000 profile+verified-email enriches (aiArk.enrichPerson, 0.1), ~1,000 email verifications (waterfall.verifyEmail, 0.1), or ~50 fully enriched contacts (waterfall.enrichContact, 2). The quickstart demo spends about 0.5. Say the free balance out loud before the first paid call on a new account.

--email is the one to reach for in an agent or sandbox shell: it never opens a browser, and where there is no terminal to prompt at, the first call sends the code and exits so you re-run with --code. To keep the code out of shell history, pass it on stdin: echo 123456 | cargo-ai login --email [email protected] --code -. Signing in with an address that already has an account resolves to its existing workspace rather than creating one, so this is safe to re-run.

--oauth runs the same OAuth 2.0 Device Authorization Flow it always did, and still needs a human at the verification URL. Use --token for CI, with a workspace-scoped token from Settings > API; token values are shown only once, so store one immediately in a secrets manager.

Without a global install, prefix every command with npx @cargo-ai/cli instead of cargo-ai.

These skills also install as a native agent plugin for Claude Code, Codex, and Cursor (one repo, three targets) — plugin users get the same skills plus the approval hook and session-lifecycle hooks bundled, with no separate installer. See the repo README.md for per-target install steps, and use one channel: plugin or skills add, never both (duplicates every skill).

All commands output JSON to stdout. Failed commands exit non-zero and return {"errorMessage": "..."}. For the full setup conventions that every capability skill links to (token scopes, async polling, admin-only commands), see references/prerequisites.md.

Every Cargo session has three jobs

Automated on Claude Code. Jobs 1 and 3 (refresh + session register/finalize) run on their own when either the Cargo plugin is installed (its bundled SessionStart/Stop/SessionEnd hooks handle them) or the hooks from the Cargo bootstrap installer — documented under Staying current → Claude Code in the repo README.md — are present. The Stop hook also checkpoints the session row each turn, so a session that never reaches SessionEnd still shows recent context instead of a bare placeholder. Do these by hand only when neither is installed (or on agents without lifecycle hooks). Job 2 (reporting) is always your responsibility — it can't be automated, and neither can the two asks at the end of Job 3 (share the session, star the repo): a hook can print, but it can't take a Y/N.

Never run that installer on the user's behalf without asking. Its documented form pipes a network-fetched script into a shell, so it is the user's call, made by the user, in their own terminal — point them at the README rather than reaching for the command yourself. If they want to inspect it first, the README also gives the download-once-then-run form; tell them to prefer it, because fetching twice (read, then pipe) proves nothing about what the second request serves.

1. At session start — refresh and register

Before any other Cargo command, refresh the CLI and skills, then register the session in workspace management:

# Refresh — idempotent, ~10s. Skills first, then the CLI at the version the
# bundle pins. The pin file `cli-version` sits in the same directory as this
# SKILL.md — read it from wherever you loaded this skill (on Claude Code with
# `skills add` that is ~/.claude/skills/cargo/; plugin installs handle this
# automatically via their SessionStart hook). Fall back to latest.
npx -y skills add getcargohq/cargo-skills
npm install -g "@cargo-ai/cli@$(cat <path-to-this-skill-dir>/cli-version 2>/dev/null || echo latest)"

# Register the session (placeholders OK — overwritten at session end)
cargo-ai workspaceManagement session upsert \
  --session-id <session-id> \
  --title "Agent session <session-id>" \
  --summary "Session in progress."

Skip the refresh only if the user explicitly pinned a version — and skip the skills add entirely if the skills came from a plugin (the plugin owns them; a parallel skills add duplicates every skill). Skip the session upsert only if the user opted out or no session id is available.

Why the pin: cargo/cli-version is bumped in lockstep with these skills (a PR from the CLI release pipeline), so the CLI you install is the one this bundle was written against — no docs/CLI drift mid-session. If the pin file is missing or unreadable, latest is the safe fallback. To move the pin, merge the pending version-bump PR on getcargohq/cargo-skills (or edit cargo/cli-version) — the next session refresh converges automatically.

The pin is also what keeps this refresh from being a blind auto-update: the version installed is a reviewed constant committed to this repo, not whatever latest resolved to this morning, and moving it is a human merge. Two things follow for you as the agent. The refresh installs a global npm package and rewrites the skills bundle on disk — surface that the first time you run it in a session rather than doing it silently, and skip it entirely if the user has pinned a version or asks you not to. And treat the pin as read-only: bump cargo/cli-version only when the user explicitly asks, never to work around a failing command.

2. Mid-session — re-refresh, or escalate when stuck

Re-refresh the CLI and skills mid-session when:

• A documented CLI flag or response shape doesn't match what you observe (a fix may have shipped since session start).
• The user explicitly asks ("bump cargo", "make sure I'm on latest").

Send a workspace management report when the CLI is failing in a way the skill references and --help cannot resolve, the user or agent is repeatedly retrying the same command without progress, the syntax for a flag / JSON payload is unclear, or a needed capability seems missing:

cargo-ai workspaceManagement report create \
  --title "<one-line summary of the problem>" \
  --description "<exact command(s) tried, errorMessage, expected vs actual, UUIDs involved>"

Trigger conditions (any one is enough):

• A command failed ≥ 2 times in a row on the same task and the cause is not obvious.
• The CLI is being misused and the correct usage is not discoverable from the skills, examples, or --help.
• A documented behavior contradicts what you observe.
• A feature appears to be missing entirely.

This is the official feedback channel — every report is reviewed by the Cargo team and used to improve the CLI and these skills. It carries wins as well as failures: a session-share (below) files through the same command. Do not give up silently — file a report. See ../cargo-workspace-management/SKILL.md (Reports section) and ../cargo-workspace-management/references/examples/reports.md for templates.

3. At session end — finalize the session row, then ask to share

Produce a short title (5–8 words) and a 1–2 sentence summary of what the session actually worked on, then overwrite the placeholder row and stamp finished_at:

cargo-ai workspaceManagement session upsert \
  --session-id <claude-session-id> \
  --title "<5-8 word title>" \
  --summary "<1-2 sentence summary of what was accomplished or attempted>" \
  --finished

--title and --summary are required (NOT NULL). --finished stamps finished_at = now; pass --finished-at <iso> for an explicit timestamp.

Then ask once, at the natural end of the session:

"Send this session's activity to the Cargo team so they can improve the experience? (Y/N)"

On yes, file a session-share report (consented session traces are the fastest product-learning loop the team has):

cargo-ai workspaceManagement report create \
  --title "Session share: <5-8 word session title>" \
  --description "<what the user tried to accomplish, the commands/recipes used, what worked, where friction appeared, credits spent — no secrets or record-level data>"

On no, don't ask again this session. Skip the ask entirely for trivial sessions (a single lookup, no paid actions). See ../cargo-workspace-management/references/examples/reports.md for the session-share template.

Then, if the session went well — offer to star the repo

A star is the user's endorsement, not yours. Never run the command unprompted; ask, and act only on an explicit yes. Silently starring from a skill file is astroturfing with someone else's GitHub account.

Ask only when all of these hold:

• The session produced a real deliverable (same bar as the session-share ask — skip trivial sessions).
• Nothing is still failing or unresolved. Asking after a broken session reads as tone-deaf.
• The marker file ~/.config/cargo-ai/.star-asked does not exist — this is a once per machine ask, not once per session.

# gate
test -f ~/.config/cargo-ai/.star-asked || echo "ask"

"Glad that worked. Want me to star getcargohq/cargo-skills for you? (Y/N)"

On yes (gh must be authenticated with the repo or public_repo scope — note there is no gh repo star subcommand):

gh api -X PUT /user/starred/getcargohq/cargo-skills   # 204 No Content = starred

Touch the marker on either answer, so a no is never re-asked and a yes is never double-asked:

mkdir -p ~/.config/cargo-ai && touch ~/.config/cargo-ai/.star-asked

If gh is missing or unauthenticated, don't fix it and don't offer a workaround — say the repo is at https://github.com/getcargohq/cargo-skills and move on. This is the lowest-stakes item in the session; it never becomes a task.

Skills at a glance

Declarative (CDK) vs imperative (CLI) — pick the mode first

Two ways to create/manage the same Cargo resources. Decide which the task wants before picking a domain:

• Declarative → cargo-cdk. The user is managing resources as an artifact: "set up / bootstrap a whole workspace as code", "make this reproducible / version-controlled / in git", "deploy these connectors + models + agents together", or anything that should be re-runnable and diffable across environments. Define it in define* files and cargo-ai cdk deploy.
• Imperative → the matching capability skill below. The user is doing a one-off operation or exploring: "create one connector", "add a column", "list connectors", "run this workflow", "query storage", "read a memory". A read, ad-hoc query, or single mutation that needn't live in code.

When unsure: should the result be committed and re-deployable? Yes → CDK. A quick action or a read → the capability skill.

Onboarding skill

Load for a brand-new user or an empty workspace.

Skill	Load when you need to…
cargo-quickstart	Run the guided first-run demo: one persona question → 25 leads in under two minutes → cost receipt → save as a recurring play. Routes to cargo-gtm afterwards.

Outcome skill

Load when the user states a real-world goal.

Skill	Load when you need to…
cargo-gtm (recap)	Any GTM task — sourcing, enrichment, verification, scoring, sequencing, CRM sync, signal monitoring (job changes, funding, tech-stack/hiring intent). Routes via recipes (recipes/), guides (guides/), and provider playbooks (provider-playbooks/).

Capability skills

Load for a specific CLI domain. The first link in each row jumps to the actual SKILL.md; the parenthetical jumps to the recap on this page.

Skill	Load when you need to…
cargo-orchestration (recap)	Execute actions, run workflows, trigger batches, chat with agents, query orchestration with SQL (ClickHouse)
cargo-analytics (recap)	Download run results, export segment data, monitor error rates and metrics
cargo-billing (recap)	Check credit usage, view subscription details, track costs per workflow or connector
cargo-diagnostics (recap)	Diagnose after the fact: trace why one run misbehaved, sweep a batch/play for errors grouped by root cause, profile where a play's credits go
cargo-observability (recap)	Create and manage alerts — scheduled threshold checks on spans/runs/records, a model's health, or a SQL query — that fire actions (connector/tool/agent runs) on breach. Proactive counterpart to diagnostics
cargo-storage (recap)	Inspect or modify data models, columns, datasets, and relationships; query workspace storage with SQL
cargo-segmentation (recap)	Build and manage segments — the saved filters that name the audience for a batch, a play trigger, or an export — and read their change (delta) feed
cargo-connection (recap)	Manage connector authentication, discover available integrations and their actions
cargo-ai (recap)	Create and configure agents, configure releases, attach knowledge for RAG, manage MCP servers and memories
cargo-content (recap)	Upload and organize knowledge files, build native/connector-backed knowledge libraries for RAG (the content domain)
cargo-context (recap)	Browse/read/write/edit the workspace's git-backed GTM context repo, run commands in its runtime sandbox, inspect the knowledge graph
cargo-hosting (recap)	Scaffold, deploy, and promote hosted apps (Vite SPAs on *.cargo.app) and edge workers (serverless HTTP handlers), and manage their deployments
cargo-cdk (recap)	Declarative — spans every resource type. Define a whole workspace in code (define* builders) and deploy it with cargo-ai cdk (init → types → plan → deploy). Use for workspace-as-code / reproducible / version-controlled setups; see "Declarative vs imperative" above.
cargo-mailbox-management (recap)	Provision sending mailboxes Cargo owns, run warm-up and the 5→40/day send ramp, send with the sendEmail action, and read threads, replies, delivery events, and suppressions
cargo-workspace-management (recap)	Invite users, create API tokens, organize folders, manage roles, report CLI issues to management
cargo-mcp (recap)	Drive Cargo from the hosted MCP server at https://mcp.getcargo.io/mcp with no CLI install — connect a client, discover and price an action, execute one record or a batch, poll it, read models; and route between the MCP tools and the CLI

Agent knowledge for RAG: files + libraries live in the content domain → cargo-content; how they attach to an agent → cargo-ai. (Files/libraries moved out of the old ai file … path in CLI ≥ 1.0.19.)

These skills vs an MCP server

Three distinct things wear the name MCP here. They share no answers, so establish which one is meant before replying:

	What it is	Skill
Hosted server	Cargo's own endpoint at https://mcp.getcargo.io/mcp. Thirteen platform tools (discover, price, execute, poll, read models), plus whatever this workspace published. The way to drive Cargo with no CLI installed.	cargo-mcp
Workspace server	A curated set this workspace publishes (ai mcp-server create --actions … --resources …), served to any stdio client by cargo-ai mcp.	cargo-ai
Agent MCP client	Somebody else's MCP server attached to a Cargo agent (release update-draft --mcp-clients).	cargo-ai

The first is new and is what "does Cargo have an MCP server?" now means. It authenticates by OAuth discovered from its own 401 challenge, or by a workspace-scoped bearer token:

claude mcp add --transport http cargo https://mcp.getcargo.io/mcp

The second is the curation path, and remains the right answer when a workspace wants to expose one approved tool rather than the whole platform:

claude mcp add cargo -- cargo-ai mcp                    # the platform MCP
claude mcp add cargo -- cargo-ai mcp --server <uuid>    # a curated server instead

With no --server, the bridge uses CARGO_MCP_SERVER_UUID when set, otherwise the platform /mcp. (Older CLIs instead fell back to "the workspace's only MCP server" and failed outright when there wasn't exactly one.)

Route between the CLI and either MCP surface by shape of the request:

	These skills (CLI)	An MCP server
What it is	The whole CLI surface, every domain	The platform runtime tools, plus whatever the workspace chose to expose
Best for	Anything that builds something reusable: workflows, plays, schema changes, CDK deploys, diagnostics, exports, warehouse SQL	In-conversation execution: look this record up, enrich this list, run this one approved tool
Cost control	Full pilot → approval → receipt discipline (../cargo-gtm/references/cost-discipline.md)	Per-call; search_actions returns each action's credit cost before you run it
Reproducible	Yes — commands, plays, and CDK files are artifacts	No — a tool call leaves no artifact behind

Rule of thumb: anything the user will want to re-run or version belongs in the CLI. Never fan an MCP tool out record-by-record over a list — that is what execute_action_batch (and orchestration action execute-batch on the CLI) exists for, and it is cheaper and observable. Conversely, when the workspace has already curated a tool for a job, calling it beats hand-assembling the same thing from raw actions.

CLI domains without a dedicated skill yet

The CLI exposes several domains that no capability skill wraps yet. Reach for them directly (cargo-ai <domain> --help) when a task needs them, and file a workspaceManagement report if the surface is unclear:

CLI domain	Covers
expression	Recipes and expression evaluation (eval, recipe) — generate/evaluate the template expressions used in node graphs.
system-of-record	System-of-record, client, and log operations.
revenue-organization	Allocations, capacities, members, territories (revenue/territory planning).
user-management	Current-user operations with no workspace context.

Dependency rules in practice:

• cargo-gtm delegates to capability skills via relative paths (../cargo-orchestration/...). Capability skills never reference cargo-gtm.
• cargo-workspace-management provides auth context for every skill — set it up first.
• cargo-storage, cargo-connection, and cargo-ai are peer skills that supply UUIDs to cargo-orchestration. They don't depend on each other.
• cargo-content owns workspace files and libraries (the content domain). It produces file/library UUIDs that cargo-ai consumes as agent release resources (RAG). Uploaded content files also surface read-only under .files/ in the cargo-context runtime sandbox.
• cargo-mailbox-management owns sending inboxes (the mailboxManagement domain) — provisioning, warm-up, the send ramp, threads, events, and the workspace suppression list. It deliberately does not send: delivery is the sendEmail native action under cargo-orchestration, which is why a send inherits orchestration's pacing, retry and credit accounting. The mailbox itself is also declarable as code via CDK's defineMailbox (with defineDomain for the sending domain).
• cargo-cdk is cross-cutting: it's a declarative authoring mode that produces the very connectors/models/plays/agents/etc. the imperative capability skills manage one at a time. Route to it when the task is "manage the workspace as code" (reproducible, in git, multi-resource); route to the imperative domain skills for one-off ops, reads, and ad-hoc queries. See "Declarative vs imperative" under Skills at a glance.
• cargo-context is orthogonal to the workflow-execution flow. It touches the git-backed GTM knowledge base (markdown/MDX), not storage or workflow runs. Use it for capturing/editing the workspace's prose context — personas, plays, proof, objections, signals — and for inspecting the typed knowledge graph.
• For SQL queries against storage, use cargo-ai storage query execute "<sql>" (tables as <datasetSlug>.<modelSlug>). Load cargo-storage to discover dataset and model slugs, and to fetch the DDL when you need column types or the SQL dialect.
• For SQL queries against orchestration runtime tables (runs, batches, spans, records) — error rates, per-node failures, time-series — use cargo-ai orchestration query execute "<sql>". Workspace scoping is automatic; tables are referenced without a schema prefix.
• Before building a workflow node graph, load cargo-connection to get connectorUuid and actionSlug. If any node calls a credits-based provider action, also load cargo-gtm and read that provider's playbook (../cargo-gtm/provider-playbooks/<slug>.md) — including its Recurring use section whenever the workflow is a scheduled tool or play, since a bad config or wrong cadence re-bills on every run. This applies even when the task arrived through cargo-orchestration or cargo-cdk directly, without a GTM framing.
• Before executing a workflow that uses an agent node, load cargo-ai to get agentUuid.
• After runs complete, load cargo-analytics to download results or measure performance. For action output retrieval, prefer cargo-ai orchestration run download-outputs over run download — the former returns a signed-URL CSV/JSON of just the output node's data.
• Load cargo-billing to understand credit consumption for any of the above.
• When a run failed, a run "succeeded but looks wrong", a batch has errors, or a play costs too much, load cargo-diagnostics — it sequences the run get / orchestration-SQL / billing surfaces into forensic runbooks (trace one run, sweep a batch, profile credit spend).
• To be told about a problem before you go looking — an error-rate spike, a cost ceiling, a slow node, a stalled sync, a workflow that stopped running — load cargo-observability. It creates alerts: scheduled threshold checks over the same telemetry (spans/runs/records), a model's health, or a SQL query, that fire actions on breach. Diagnostics is reactive (explain what happened); observability is proactive (watch for it). Alerts can also be declared as code via CDK's defineAlert.

Per-skill critical rules

The non-obvious rules for each skill — the things that fail silently or cost money if you guess. Each skill's own SKILL.md carries the full surface; these are the ones worth knowing before you pick.

cargo-gtm

Recipes shipped:

Recipe	Use when…
recipes/source-planning.md	Decide the source before spending: probe candidates, cost per hit.
recipes/prospecting.md	End-to-end find → enrich → verify → sync (P1/P2/P3 variants).
recipes/build-tam.md	Build a Total Addressable Market list at scale (100–10,000 companies).
recipes/linkedin-url-lookup.md	Resolve LinkedIn URL from name + company with strict validation.
recipes/portfolio-prospecting.md	Investor / accelerator → portfolio companies → contacts.
recipes/job-change-monitoring.md	waterfall.detectJobChange (cargo-unique) on a contact segment.
recipes/funding-watch.md	Track companies that recently raised funding.
recipes/tech-intent.md	Find companies by tech-stack or hiring-intent signals.
recipes/icp-discovery.md	Diff Closed-Won vs Closed-Lost segments, surface ICP signals.
recipes/custom-datapoints.md	Design which custom attributes + live signals to collect, gated on a real source and cost.
recipes/outreach-activation.md	Turn a signal segment into send-ready outreach (enrich → verify → personalize → sequencer handoff).
recipes/ads-audience-activation.md	Push a segment to Google Ads Customer Match / LinkedIn Matched Audiences.
recipes/review-and-iterate.md	Human review loop for judgment output; corrections become permanent rules.
recipes/re-engagement.md	Wake up stale contacts only when a fresh signal fires (job change, funding, tech intent).
recipes/lost-deal-revival.md	Revive Closed-Lost CRM deals by branching on lost_reason (champion left, budget, timing).
recipes/account-expansion.md	Multi-thread customer accounts — net-new buyers, deduped against the Contacts model.

Priority provider stack (recipes lead with these): salesNavigator (sourcing), cargo native (firmographics + signals), aiArk (LinkedIn-anchored enrich + cheapest search), waterfall (multi-source enrichment + email verify + job-change), FullEnrich (premium contact lookup), apolloio (1-credit niche-coverage enrich), theirStack (tech-stack + hiring intent), peopleDataLabs (heavyweight backfill). Already have LinkedIn URLs (or an event URL)? Don't source — go straight to aiArk.enrichPerson (0.1, profile + verified email, bills 0 on no-email), or linkedin (enrichProfile/enrichCompany 0.25, extractEventAttendees) when you don't need the email; these are the cheapest URL-anchored enriches and easy to miss because the stack above is sourcing-first.

Critical rules:

• Acceptable use gates every step that touches a person (../cargo-gtm/references/acceptable-use.md): B2B professional identities from licensed providers only, three free blocking checks before any outreach step (basis, suppression, relevance), and a refusal list — undifferentiated fan-out, consumer targeting, lists with no stated origin, contacting a suppressed record, filter or identity evasion, auto-dialing, batch-blasting LinkedIn engagement actions. The pack never sends: outreach stops at send-ready variables for the user's own sequencer.
• All recipes use credits-based actions (cargo-ai connection integration list → 145 credits-based actions across 120 integrations).
• Action shape: {"kind":"connector","integrationSlug":"<slug>","actionSlug":"<slug>"} — no config on a top-level action, and connectorUuid is never nested inside one; it sits at the top level of a node.
• Output retrieval: cargo-ai orchestration run download-outputs --output-node-slug <slug> (NOT run download).
• peopleDataLabs filter shape: searchX uses cargo's {conjonction, groups, conditions} shape; queryX takes a PDL SQL string — never Elasticsearch.

cargo-orchestration

Critical rules:

• See the decision flowchart at the top of ../cargo-orchestration/SKILL.md for when to use action execute vs run create vs batch create.
• Never enroll a full batch on the first attempt. batch create / action execute-batch fan out across every record in the source. Sample 10–20 records, report observed cost + hit-rate, then ask the user to approve the full enrollment — quoting the record count and the credit estimate. Mechanics: ../cargo-orchestration/SKILL.md → "Create a batch"; spend rules: ../cargo-gtm/references/cost-discipline.md §1.
• Search for the action; never browse the catalog for it. cargo-ai orchestration action list <keywords> [--kind connector|native|tool|agent] [--integration-slug <slug>] [--limit 20] covers the integration catalog, Cargo native actions, workspace tools, and agents in one free call, and returns a ready-to-paste action object (connectorUuid resolved) plus the action's credit costs. Its sibling cargo-ai connection action search <keywords> is connector-only but adds --credits-only and --category, the two filters action list lacks. Both beat paging connection integration list; reach for integration get <slug> only once you have picked the action and need its full input schema.
• Omit config on action execute / action execute-batch — inputs go in --data / --records. That is the shape action list returns, so its result pastes straight in. action get-output-schema is the exception and still requires it (400 at action.config without "config": {}), as do workflow nodes, alert --actions, play healthAlertActions, and agent / MCP-server --actions. Inputs misplaced in config are now dropped rather than rejected — the action runs with no input and the error never mentions config.
• action execute is the default for running an operation; node execute is debug-only. Use node execute only to test a single node of a workflow you're authoring — it requires --workflow-uuid, --release-uuid, --node, --computed-config and --context (all five). Anything else — enrich a record, call a connector action, invoke a tool or agent — goes through action execute / action execute-batch.
• Prefer built-in actions + expressions when building a node graph. Avoid python, script (JS), and raw HTTP nodes unless necessary: use variables for transforms, the native agent node for LLM calls, the integration's dedicated connector action for APIs, and branch/filter/switch for routing. See ../cargo-orchestration/references/node-selection.md.
• Show a node graph, don't describe it. Before deploying a draft, and whenever the user asks what a workflow or play does: cargo-ai orchestration node diagram --workflow-uuid <uuid> --raw (free, runs nothing, CLI ≥ 1.0.54; references/node-diagram.md). Routing, fallback edges, and which nodes bill are what's being approved. Let the command draw it rather than transcribing — node slugs repeat within a release, so a hand-drawn diagram keyed on slug merges nodes that aren't the same.
• Filter JSON uses conjonction (not conjunction) — breaks silently if misspelled.
• Query orchestration runtime tables (ClickHouse) with cargo-ai orchestration query execute "<sql>" against runs, batches, spans, records (no schema prefix; workspace scoping is automatic).
• For SQL against workspace storage (Companies, Contacts, …), use cargo-ai storage query execute "<sql>" — documented in cargo-storage.
• All operations are async — poll or pass --wait-until-finished. See Async polling.

cargo-analytics

Critical rules:

• segment download requires --model-uuid, not --segment-uuid.
• For batch result download, get the output-node-slug from release get <release-uuid> → nodes[].slug.
• For billing and credit usage, use cargo-billing instead.
• Analytics answers "what happened" (metrics, counts, exports). When the question is why — a failing run, a batch full of errors, surprising cost — hand off to cargo-diagnostics; its sweep runbook picks up exactly where analytics' error counts leave off.

cargo-billing

Critical rules:

• Requires a token with admin access.
• Invoice amounts are in cents — divide by 100 for dollars.
• subscriptionAvailableCreditsCount - subscriptionCreditsUsedCount from subscription get = remaining credits.

cargo-diagnostics

Critical rules:

• Start with the sweep when you don't know which run to look at; it ends with exemplar UUIDs for the trace.
• runContext is the source of truth for what a node produced; an execution's title is a truncated summary — never evidence.
• Credit attribution (billing …) needs an admin token; the SQL and run get steps don't.
• Any fix that re-runs paid nodes goes through the pilot gate in ../cargo-gtm/references/cost-discipline.md.
• Diagnostics explains; it doesn't export. For bulk retrieval after the diagnosis (run download-outputs, batch download, segment download) go back to cargo-analytics.
• Present conclusions first, evidence as compact tables — per references/interaction.md (in the cargo router skill).

cargo-observability

Critical rules:

• preview before create. alert preview --scope … --threshold … [--window-minutes 60] evaluates now without firing — the only way to size a threshold against reality and to catch an invalid scope/threshold pairing (outcome: "notComputed") before it becomes a schedule that errors every tick.
• Scope and threshold are a matched pair. Telemetry metrics (errorRate, duration+aggregation, credits+aggregation, count) need spans/runs/records; query needs a query scope; recordsCount/recordsShare/freshness/syncDuration need model. Full matrix + units in references/scopes-and-thresholds.md.
• Empty window vs real zero. Most metrics report an idle window as empty (healthy, no fire). Only count and recordsCount return a real 0 — pair with lte 0 for a dead-man's switch (alert when a workflow stops, a model empties).
• Firing is at-most-once and costs credits. Actions fire as runs (runUuids on the event); a sustained breach re-fires once per tick it's still true, never on the same rows twice. If an action calls a paid provider, apply ../cargo-gtm/references/cost-discipline.md — a scheduled alert re-bills on every breach.
• --enabled is strict (true/false only); model-scope filter uses the segmentation shape spelled conjonction.
• Permissions are observability:read / observability:write (not admin-only). The declarative equivalent is CDK's defineAlert — see cargo-cdk.

cargo-storage

Critical rules:

• Query via cargo-ai storage query execute "<sql>" (or storage query download --query "<sql>" for full exports) using <datasetSlug>.<modelSlug> table names (e.g. default.companies). model get-ddl is optional — useful for column types and SQL dialect.
• For SQL against orchestration runtime tables (runs/batches/spans/records), use cargo-ai orchestration query execute "<sql>" — documented in cargo-orchestration.
• For advanced record queries (filtering, sorting, pagination), use segmentation segment fetch — documented in cargo-segmentation.
• storage relationship set replaces the dataset's whole relationship set — anything absent from the payload is deleted. list first, send the full array back.

cargo-segmentation

Critical rules:

• Filter JSON uses conjonction (not conjunction). A misspelling is not an error — the filter silently matches nothing.
• Size before you spend. segment fetch --limit 1 counts an inline filter for free; a saved segment's recordsCount is the authoritative size. Quote it before proposing any paid run over the audience.
• segment download takes --model-uuid plus the filter, never --segment-uuid.
• change list needs --segment-uuid; change fetch needs the change UUID plus --kinds (added/updated/removed/unchanged).
• updatedRecordsCount stays 0 unless the segment was created with --tracking-column-slugs — those columns define what "updated" means.
• Segments named GENERATED_PLAY_SEGMENT (fromPlay: true) are owned by a play. Never edit or remove them by hand.

cargo-connection

Key concepts:

• Integration = external service type (HubSpot, Clearbit, Salesforce, …)
• Connector = authenticated instance of an integration (referenced by connectorUuid in nodes)

cargo-ai

Critical rules:

• Knowledge for RAG attaches to an agent via the release's resources: files + libraries come from cargo-content. Wire them in with release update-draft --resources … then release deploy-draft.
• cargo-ai mcp with no --server now bridges the first-party platform MCP (mcp.getcargo.io/mcp), not "the workspace's only MCP server". ai mcp-server still builds a curated server; pass its uuid with --server. See "These skills vs Cargo's MCP surfaces" above.
• CLI ≥ 1.0.19: files and libraries moved out of the ai domain into the top-level content domain (now the cargo-content skill). The old cargo-ai ai file … commands no longer exist.

For using agents (sending messages, multi-turn chat, polling), use cargo-orchestration.

See ../cargo-ai/SKILL.md for model and temperature guidance by use case.

cargo-content

Critical rules:

• New top-level content domain in CLI ≥ 1.0.19 — cargo-ai content file … / cargo-ai content library …. The old cargo-ai ai file … path is gone (unknown command → you're on the old path; bump the CLI).
• A file or library is inert until attached to an agent's deployed release resources — that wiring lives in cargo-ai.
• Uploaded content files are also readable (read-only) under .files/ in the cargo-context runtime sandbox.
• For batch-run input files (CSVs that drive a batch), use cargo-ai workspaceManagement file upload (a different surface) — see cargo-workspace-management.

cargo-context

Key concepts:

• Context repository = the GitHub repo backing the workspace's context. Canonical example: getcargohq/cargo-workspaces. Files use kebab-case.md names, YAML frontmatter with required title + description, and domain/slug cross-refs (no .md).
• Runtime sandbox = a checked-out, executable copy of the context repo. runtime write and runtime edit push to the default branch; runtime execute does not push.
• Knowledge graph = the typed graph over every md/mdx file, with frontmatter and outbound cross-refs per node. Built via cargo-ai context graph get.

Critical rules:

• runtime write / runtime edit commit and push. runtime execute is ephemeral — use it for grep/ls/inspection, never for persistent changes.
• runtime edit --old-string must match the file content exactly once. Read first, copy whitespace verbatim.
• Set title + description frontmatter on every .md/.mdx file — a strong convention, not enforced: missing/malformed frontmatter is still committed, it just indexes poorly (graph falls back to filename + first paragraph, and reads summary, not description).
• Graph edges form only from frontmatter references:, markdown links, or wikilinks — a bare path in prose creates no edge. Cite source files in references:.
• For domains, conventions, and per-domain templates, see ../cargo-context/references/conventions.md.
