Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00142 | $0.04021 |
| Opus 5 | $0.00071 | $0.02011 |
| Sonnet 5 | $0.00028 | $0.00804 |
| Haiku 4.5 | $0.00014 | $0.00402 |
Grade A, and why
cometchat-js-v5-sdk 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 today.
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 — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Ground truth:
@cometchat/calls-sdk-javascript@5+ catalogweb-calls-v5.json(the closed symbol list — everyCometChatCalls.*below exists in it). Official docs:/calls/javascript/**= v5 · Docs MCP. Fetch exactSessionSettingsfields, event names, and action-method signatures from the docs (references/docs-map.md) — never memory. APPEND to the user's app — additive wiring only (RULES.md). This is the HEADLESS path (no UI Kit); for the prebuilt drop-in call UI usecometchat-react-v7-callsinstead.
Companion skills (read first)
- Standalone/headless entry — this skill owns its own package (the Calls SDK) and has no
-coresibling; it is self-contained for meet-style calling. - For 1:1 RINGING only it also drives the Chat SDK (
@cometchat/chat-sdk-javascript@4) for call signaling — signatures fetched from docs viareferences/docs-map.md(§ "1:1 RINGING"). It does NOT depend on the React UI Kit. - Prefer the UI Kit instead? If the app also wants chat and a prebuilt call UI, use
cometchat-react-v7-core+cometchat-react-v7-calls— not this skill.
Use this skill when
"add calling from scratch / without the UI Kit", "standalone voice/video", "build my own call screen", "headless calls SDK", "meeting-room join by session id", "one-on-one ringing call". Precondition: the caller chose the from-scratch / standalone path (the "add calling" router asks this). If they want the prebuilt call UI, route to cometchat-react-v7-calls.
Prerequisites & install
npm install @cometchat/calls-sdk-javascript@5
- 1:1 ringing additionally needs the Chat SDK for signaling:
npm install @cometchat/chat-sdk-javascript@4 - Credentials/env: App ID · Region · Auth Key (dev only). To fetch from the dashboard, load the CLI on demand —
npx @cometchat/skills-cli@3 auth login→provision use --app-id <id> --json(writes.cometchat/config.json;@3pins the CLI major that matches the v5 skills). Or paste manually from Dashboard → Credentials. Mint auth tokens server-side for production; never ship the Auth Key. HTTPS (orlocalhost) is required for camera/mic (getUserMedia).
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

cometchat-js-v5-sdk is a skill published in the GitHub repository cometchat/cometchat-skills (104 stars, last pushed yesterday), licensed MIT. It adds 142 tokens to every session and 4,021 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-12.
