Calle

CALL-E

Use this skill when the user wants Codex to use CALL-E through the calle CLI. This plugin version intentionally calls the CLI instead of configuring Codex to connect directly to the remote MCP server.

When to use

Use this skill for:

• verifying CALL-E setup in Codex
• checking whether the calle CLI is available
• recovering from missing or expired CALL-E authentication
• listing available CALL-E MCP tools through the CLI
• planning a phone call
• running a planned call after planning returns complete run credentials
• checking a call run status
• reporting the final call summary, details, and transcript when a call reaches a terminal status

Do not use this skill when the user only wants a call script, roleplay, simulated conversation, or general contact lookup that does not require CALL-E.

Tool routing

When this Codex plugin skill is active, use only the calle CLI flow documented below. Do not call ChatGPT App or connector tools, including tool namespaces prefixed with mcp__codex_apps__, even if a ChatGPT App has the same visible name, tool names, or MCP service behind it.

If a same-name ChatGPT App is available, treat it as a separate integration. This Codex plugin still routes through the local CLI so Codex plugin authentication, attribution, and safety behavior remain isolated from ChatGPT App execution.

Safety and consent

• Real phone calls may contact external people or businesses.
• Do not place a real call unless the user clearly intends to do so.
• Always plan first.
• If the user asked to place a call, run it immediately after planning returns a valid plan_id and confirm_token.
• If the user asked only to verify setup or only to plan, do not run the call.
• Do not guess phone numbers, country codes, language, region, plan_id, confirm_token, or run_id.
• Do not print, request, or expose access tokens.

CLI selection

All CLI commands run from this Codex plugin must include the CALL-E integration attribution environment:

env CALLE_SOURCE=codex CALLE_INTEGRATION=codex_plugin CALLE_INTEGRATION_VERSION=0.1.11

Use the first command form that works.

Prefer the repository-local CLI when the current workspace contains it:

env CALLE_SOURCE=codex CALLE_INTEGRATION=codex_plugin CALLE_INTEGRATION_VERSION=0.1.11 node packages/cli/bin/calle.js

If the repository-local CLI is unavailable, use the global command:

env CALLE_SOURCE=codex CALLE_INTEGRATION=codex_plugin CALLE_INTEGRATION_VERSION=0.1.11 calle

If neither command works, use the npm package through npx:

env CALLE_SOURCE=codex CALLE_INTEGRATION=codex_plugin CALLE_INTEGRATION_VERSION=0.1.11 npx -y @call-e/cli

Only tell the user to install the CLI globally if npx is unavailable, network access is blocked, or the user explicitly wants a persistent global command.

Readiness flow

Use this flow whenever this Codex plugin is actively invoked for a CALL-E request. Run it before call planning, before tool listing, when setup is uncertain, when auth fails, or when the user asks to verify CALL-E setup:

1. Check CLI availability with --help.
2. Run auth status.
3. If auth status reports usable: false, or if this flow is running after any command returned auth_required, do not continue to call planning or mcp tools yet. Run blocking auth login and keep that command running until it exits. If the preceding command returned auth_required while auth status still reported usable: true, add --force-login so the CLI does not rely on a locally usable but server-rejected token. Do not use auth login --start-only --no-browser-open for the default Codex plugin flow.
4. When auth login prints the brokered login URL to command output or stderr, immediately show the first authorization help with that URL. Keep waiting for the same auth login command to complete; do not ask the user to reply after browser authorization.
5. If the successful auth login JSON included assistant_hint.message, show that post-auth success message in the next user-facing reply. If the user already gave a call goal, continue the original workflow after the message; otherwise ask for the phone number and call goal, or offer a test call.
6. After login completes, run mcp tools.
7. Confirm that plan_call, run_call, and get_call_run are available.

Setup verification must not place a real phone call. Use only help, auth, and tool-listing commands until the user asks for a call workflow.

First authorization help template:

Hi, I'm CALL-E 👋

I can help you make phone calls, ask for information, and handle phone-related tasks. I'll also keep you updated on the call status, what was discussed, and the key points.
Before we officially begin, I'll send you the call goal for confirmation.

Before we start, please complete authorization here:
<login_url>

Post-authorization success template:

Great, authorization is complete ✨

- If you already shared the call goal, I'll continue as planned.
- If you haven't, that's okay. I can help you place a test call first, or start a real call directly.

You can tell me:
- Your phone number: Used only for this service. We will not disclose it to anyone else, including the callee.
- What you want me to say: For example, "This is a test call from CALL-E. Wishing you a good day, and asking if there's anything you'd like to share."

I'll keep you updated on the phone status, call content, and summary.

Call flow

1. Use call plan first. If the user has not provided enough explicit fields for call plan, use mcp call plan_call --args-json '{"user_input":"<latest user message verbatim>"}' so CALL-E can ask for the missing details.
2. Read the returned plan_id and confirm_token.
3. If the user's request is to place a call, immediately use call run with the exact plan_id and confirm_token returned by planning.
4. Do not ask for a second confirmation between call plan and call run.
5. Read the returned run_id and latest call status. In call run output, the latest call state is in status_result.structuredContent. In call status output, the latest call state is in result.structuredContent.
6. If the latest status is not terminal, immediately show a user-visible progress update from the latest activity data before polling again. Use status_result.structuredContent.activity after call run, or result.structuredContent.activity after call status.
7. Keep using call status with that exact run_id until the call reaches a terminal status or the user asks you to stop. Poll every 10 seconds: after each non-terminal response, show the latest activity progress, wait 10 seconds, then fetch call status again. Do not stay silent until a terminal status.
8. Use call status only with a known run_id.

Terminal statuses include COMPLETED, FAILED, NO_ANSWER, DECLINED, CANCELED, CANCELLED, VOICEMAIL, BUSY, and EXPIRED.

For non-terminal statuses, reply with progress in this shape:

Phone call is in progress! Progress:
- <HH:MM:SS message>

Use one bullet per activity item, preserving the order returned by the CLI. For each item, prefer the event ts formatted as HH:MM:SS plus message. If ts is missing, use the message by itself. If there is no activity, use - Status: <status> when a status exists; otherwise use - Waiting for the next status update. Do not include the final summary, details, or transcript until a terminal status is returned.

The polling cadence is: show progress, wait 10 seconds, run call status, show new progress if still non-terminal, then repeat. Stop polling immediately when the user asks you to stop, when a terminal status is returned, or when command execution is interrupted.

When the call reaches a terminal status, reply with the final call result, including these sections in this order:

[Status]
<status>

[Call Summary]
<post_summary or summary or message>

[Details]
Callee Number: <primary callee or Not available>
Duration: <duration or Not available>
Time: <start/end time or Not available>
Call id: <call_id or Not available>

[Transcript]
<transcript or Not available.>

If the user asked for extra final content, such as key takeaways or next steps, add it after [Transcript] under a short heading. Base all final sections only on the JSON returned by call run or call status; do not invent a transcript.

If any command returns auth_required, switch to the readiness flow, complete fresh login, and then retry the original operation after login completes.

Use references/commands.md for exact command examples, supported options, and JSON handling rules.
