callwright: Instructions file for GitHub Copilot

.github/copilot-instructions.md

callwright copilot-instructions.md is an instructions file for GitHub Copilot from topness-msft/callwright. It costs 1,472 tokens per session, scanned A, original, MIT.

A project guide for Callwright, a self-hosted program that uses an AI model and Retell to place phone calls for one user.

In plain words
What is it for?
Use it when installing, running, testing, or changing Callwright, including its Node.js server, command-line tools, phone-call dispatch, and retry logic.
Why use it?
It gives an AI coding assistant the project's setup, testing, architecture, and file-path rules so changes fit the existing codebase.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is topness-msft/callwright's own configuration. It tells GitHub Copilot how to work on callwright itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything callwright configures →

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

callwright copilot-instructions.md 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 2mo 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 — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Callwright — Copilot instructions

Callwright is a self-hosted, single-user MCP server (Node.js, CommonJS) that places outbound phone calls on the user's behalf via Retell. An LLM shapes each call's direction + grounding; Callwright validates, composes, and dispatches it fire-and-forget, then fetches the outcome on demand.

Build / test / run

  • Runtime: Node >=18, "type": "commonjs". No build step.
  • Install: npm install.
  • Tests use the built-in Node test runner (no framework dependency):
    • Full suite: npm test (runs node --test, which discovers test/*.test.js).
    • Single file: node --test test/retry-core.test.js.
    • Single test by name: node --test --test-name-pattern="classifyDisconnect" test/retry-core.test.js.
  • No linter or formatter is configured — don't add one unless asked.
  • Run locally: node init.js (setup wizard) then node server.js (MCP server on :8787, POST /mcp). Installed globally the binaries are callwright and callwright-init.
  • Place a call from the CLI (bypasses MCP): node dispatch.js <job.json> --go.

Architecture — the core/wrapper split

The central convention: all reusable logic lives in *-core.js modules that are pure of CLI concerns (no process.argv, no stdin/stdout side effects). Thin wrappers adapt them to a surface:

  • dispatch-core.js — the pipeline: validate → profile-match → compose-vars → resolve-agent → dispatch. Both the CLI and the MCP server call this in-process.
  • dispatch.js — CLI over dispatch-core. server.js — the MCP server (Streamable HTTP + bearer auth) over the same cores.
  • Other cores: setup-core.js (provisioning/config/status), lang-core.js (runtime language add/verify/update/remove), learn-core.js (profile enrichment + new-scenario candidate staging), retry-core.js (no-answer re-dial policy), notify-core.js (optional SMS).
  • CLIs learn.js / get-call.js / update-prompt.js are similarly thin wrappers.

When adding behavior, put logic in the relevant *-core.js and keep server.js / the CLI as adapters — don't duplicate logic across the two surfaces.

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.
