ICP CLI Usage

Quick start workflow

Default to these steps unless the user asks for a specific command:

1. Create a project: icp new my-project
2. Start local network: icp network start -d
3. Deploy (builds automatically): icp deploy
4. Call a method: icp canister call <canister> <method> '(...)'
5. Verify if needed: icp network status, icp canister status <canister>

Use -e/--environment when the user specifies a target (deploy uses environments; network start uses a network name or -e).

Non-interactive project creation

icp new may prompt for template values and can fail in non-TTY contexts. Use explicit template settings to avoid prompts:

icp new my-project --subfolder hello-world \
  --define backend_type=rust \
  --define frontend_type=react \
  --define network_type=Default

Preflight checks

Use these to confirm the environment quickly:

• icp --version
• icp network list
• icp network status (or icp network ping --wait-healthy)

Command map (common tasks)

• Project lifecycle: icp new, icp build, icp deploy, icp sync
• Local network: icp network start|status|ping|stop
• Canister ops: icp canister create|install|call|status|settings
• Identities: icp identity new|list|default|principal|import
• Cycles/tokens: icp cycles balance|mint|transfer, icp token balance|transfer
• Project config: icp project show

Decision points

• Local vs mainnet: default to local if unspecified; ask for environment or network if needed.
• Identity: suggest --identity when multiple identities exist.
• Install mode: use --mode install|reinstall|upgrade only when user requests it.
• Arguments: if canister call args are unknown, recommend interactive prompt (omit args).
• Network conflicts: icp network start accepts a network name or -e; icp deploy uses -e (no -n flag).
• Environment variables: mention ICP_ENVIRONMENT when the user wants a default.

Troubleshooting local network

• Port 8000 already in use: local PocketIC binds to localhost:8000. If icp network start fails, check and stop the other process with lsof -i:8000 and kill <PID>.
• Shutdown: icp network stop (use when finished with local testing).
• Verify network: icp network status or icp network ping --wait-healthy

Tool calls

Use tool calls to validate the latest CLI help and documentation.

CLI help (preferred when available locally):

{ "tool": "Shell", "command": "icp --help" }

{ "tool": "Shell", "command": "icp canister --help" }

{ "tool": "Shell", "command": "icp network --help" }

Docs pages (when the CLI isn’t available or for citations):

  "tool": "WebFetch",

Responses

When replying to users:

• Provide the smallest set of commands to accomplish the task.
• Include flags only when necessary to meet the user’s environment or identity needs.
• Offer a short "verify" step (e.g., icp network status, icp canister status).
• Cite official docs or the CLI help when explaining flags or behavior.
• Ask for missing details only when required: environment/network, canister name, method, and args.

Self-test prompts

Use these to sanity-check outputs:

• "Start a local network and deploy" → quick start workflow + verify step.
• "Call a canister method but I don't know args" → omit args to trigger prompt.
• "Deploy to staging" → use -e staging, avoid -n.
• "Check cycles and top up" → icp cycles balance + icp canister top-up.

Examples

Create and deploy a project locally

Commands:

icp new hello-icp
cd hello-icp
icp network start -d
icp network status
icp deploy
icp canister call backend greet '("World")'

Create a project non-interactively (CI/non-TTY)

Commands:

icp new hello-icp --subfolder hello-world \
  --define backend_type=rust \
  --define frontend_type=react \
  --define network_type=Default
cd hello-icp
icp network start -d
icp deploy

Check cycles and top up

Commands:

icp cycles balance
icp canister top-up --amount 2t backend

Deploy to a named environment

Commands:

icp deploy -e staging
icp canister status -e staging
