calle-developer

calle-developer is a skill for Claude Code, Codex from CALLE-AI/awesome-phone-call-agents. It costs 51 tokens per session (1,242 once invoked), scanned A, original, MIT.

A development guide for connecting applications to the CALL-E Developer API using its TypeScript or Python software packages, or direct HTTP requests. It covers calls, published goals, structured results, recovery, and webhooks.

In plain words
What is it for?
Use it to build or debug CALL-E integrations, inspect the OpenAPI contract and installed SDK types, review request payloads, and handle idempotency, recovery, and webhooks.
Why use it?
It helps prevent mismatches between the API contract, SDK behavior, request fields, and identifiers. It also keeps application integration separate from operating calls through the CALL-E command-line tool.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

calle-developer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CALL-E developer integration

Help the developer finish their application using the current official contract and existing examples. Keep their language and framework; use direct HTTP when there is no suitable SDK. This skill adds no API or documentation MCP service.

Choose the integration and sources

For a new integration, read the quickstart and the relevant part of the SDK guide. Distinguish request-scoped Calls from running a published Goal. Calls use /v2/calls with SDK 1.0.1; Goal Runs keep their own /v1/goals interface. Do not mix their inputs or identifiers. Use the documentation index to find additional topics, not to load the entire site.

Before writing or reviewing a request, inspect the relevant operation in the OpenAPI contract. For SDK code, also inspect the installed package version and its public types or source: TypeScript or Python. HTTP fields and SDK arguments are not interchangeable. For payload reviews, inspect the SDK's request-building code and which arguments become headers rather than JSON fields; a README alone does not establish that mapping. The Calls idempotency key belongs in the Idempotency-Key header over HTTP. Cite the source used and record the package version when reporting verification. If sources are unavailable or conflict, identify the specific unverified behavior rather than inventing fields.

Read references/examples.md to choose an existing starting point. Reuse it before creating another client, receiver or schema copy. Read references/safety.md before implementing or running any live path.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
