What it does

Before touching code, the agent classifies the request, because most CometChat features need none. Some are already on, such as reactions, mentions, receipts and typing indicators. Dashboard extensions like polls, stickers, translation and link preview only need enabling in the dashboard. Host-composed features, such as pinned messages or reminders, need the extension enabled and then your own UI built with callExtension to send and fetch. AI features like smart replies need dashboard enablement and an optional component, and threads, search, custom message types, text formatters and calls take real client code.

A features file in the pack root is the ground truth for what exists, so a feature that is not listed there is never invented, and exact enablement steps are fetched from the documentation topic on each entry. The skill assumes companion skills for installation, credentials and component names. It targets the @cometchat/chat-uikit-angular package at version 5 on Angular 17 to 21.

When your agent uses it

  • Enabling a CometChat feature such as polls or reactions in an Angular app
  • Finding out whether a chat feature needs any client code at all
  • Building the UI for a host-composed extension like pinned or saved messages
  • Adding smart replies, translation or stickers to an existing chat screen

Example prompts

  • “Add polls to our Angular chat screen.”
  • “Let users save and bookmark messages in the Angular app.”
  • “Turn on smart replies and tell me whether any client code is needed.”
  • “Send a custom message type that carries an order status card.”

Requirements

  • @cometchat/chat-uikit-angular version 5 in an Angular 17 to 21 app
  • A CometChat dashboard account to enable extensions
  • The companion cometchat-angular-v5-core skill
  • Compatibility (from SKILL.md): @cometchat/chat-uikit-angular ^5 (5.1.0–5.2.0 verified); Angular 17-21

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Building a feature that is already on — hand-rolled reaction pickers are the classic. Check the "already on" list first.
  2. Assuming every extension is zero-code — 10 of them render no affordance and need CometChat.callExtension(). Equally, do not write code for…
  3. Declaring a feature absent because node_modules has no method for it — extensions have no named SDK method; they go through the generic…
  4. Re-implementing a server-side feature in the browser — localStorage, an in-memory Map, or a local BehaviorSubject where an extension…
  5. Offering a feature Angular does not have — E2E encryption, live streaming, email replies.
  6. Forgetting the dashboard step — the code is right, the feature is off, and it looks broken.
  7. Treating reactions/mentions as extensions — they are core in v5.

What it can do on your machine

Read from SKILL.md and the folder at commit 911b108. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript and html).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • cometchat.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    @cometchat/chat-uikit-angular ^5 (5.1.0–5.2.0 verified); Angular 17-21

    From compatibility in the SKILL.md frontmatter.

Context cost

CometChat Angular Features loads about 2.6k tokens when it runs, and up to ~7.2k if it reads all its reference files. Until then it costs about 259 tokens; SKILL.md has 1,141 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~259
When it runs · the whole SKILL.md, loaded when a task matches
~2.6k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~7.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

cometchat angular features v5 extensions ai reactions polls stickers translation

Ground truth: the feature existence oracle is features.angular-v5.json (pack root). A feature a user asks for MUST be an id there — if it is not listed it does not exist; do not invent it. Exact enablement steps and payloads are FETCHED from each entry's docs_topic (a PATH — resolve it against DOCS_BASE in cometchat-angular-v5-core/references/docs-map.md). UI component names come from the angular-v5 catalog.

Companion skills (read first)

  • cometchat-angular-v5-core — install, credentials, init→login→render. Assumed, never restated.
  • cometchat-angular-v5-components — component names, inputs/outputs, slots.

Use this skill when

Someone asks to add or enable a capability: "add polls", "enable reactions", "turn on smart replies".

FIRST — classify the request

Most features need no client code at all. Writing some is the most common mistake here.

ClassWhat you doExamples
Already onNothing. Confirm and show where it appears.reactions, mentions, receipts, typing, media attachments, voice notes
Dashboard extension — zero codeEnable in the dashboard. Nothing else — the kit either mounts a dedicated bubble component or renders it inline automatically.polls, stickers, collaborative whiteboard, collaborative document, message translation, link preview, thumbnail generation
Dashboard extension — HOST-COMPOSEDEnable in the dashboard, then you build the UI: CometChat.callExtension() to send/fetch, your own component to render. The dashboard toggle alone does nothing visible.pin message, save message, message shortcuts, voice transcription, rich media preview, GIFs, reminders, URL shortener, disappearing messages, support integrations
Dashboard + AIEnable in the dashboard, then optionally place a component.smart replies, conversation starter, conversation summary, AI assistant
Client codeReal wiring.threads, search, custom message types, text formatters, rich text, calls

10 of the 17 extensions are host-composed — nearly two-thirds. needs_stitching: true in features.angular-v5.json is the authoritative signal (not ui_components: three zero-code entries — message translation, link preview, thumbnail generation — legitimately have ui_components: [] because they render inline into an existing bubble/menu rather than through a separately-importable component). Verify against needs_stitching before answering, never from memory or from this table's examples alone.

Ask which app in the dashboard before telling someone to toggle something.

Already on by default — do NOT "add" these

reactions · mentions · delivery/read receipts · typing indicators · media & file attachments · voice notes.

These are core in v5, not extensions. Angular's extensions page does not list reactions or mentions, which confirms it. If one is not visible the cause is a missing @Input() or an unsized container — not a missing feature. Never write a reaction picker or typing indicator by hand.

Dashboard extensions — enabling is necessary, NOT always sufficient

Dashboard → your app → Extensions → enable. Then check the running app, because there are two kinds:

Auto-rendered — emit nothing. The kit surfaces these itself once enabled: polls, stickers, collaborative document/whiteboard (bubbles in the message list), link preview and thumbnails (inside the bubble), message translation (an entry in the message menu).

Host-composed — the kit renders NO affordance. Enabling them changes nothing visible; you must call the extension and render your own control:

ts
import { CometChat } from '@cometchat/chat-sdk-javascript';

// SEND — exact slug, endpoint and payload are on the extension's own docs page
await CometChat.callExtension('pin-message', 'POST', 'v1/pin', { msgId, receiverType });

Send is only a third of the job. You also need to FETCH the pinned/saved list back and RENDER it — full pattern, incl. the type-safe way to turn a fetched entry into displayable text: references/host-composed-extensions.md.

Currently host-composed in Angular (10): pin message · save message · message shortcuts · voice transcription · rich media preview · GIFs · reminders · URL shortener · disappearing messages · support integrations. needs_stitching: true in features.angular-v5.json is the authoritative signal — not ui_components, see the table above.

Do not conclude a feature "does not exist" because the kit has no component and the SDK has no named method for it. Extensions are reached through the generic CometChat.callExtension() — there is no pinMessage() to grep for. Searching node_modules for the SEND/FETCH calls will find nothing and that is expected.

docs_topic is a PATH, not a URL. Prefix it with DOCS_BASE from cometchat-angular-v5-core/references/docs-map.md, then append .md: {DOCS_BASE} + /fundamentals/pin-message + .md Do not hardcode https://www.cometchat.com/docs/.... DOCS_BASE may point at a docs preview while a docs change is in flight, and a hardcoded production URL silently reads the pre-change page — so you would fetch a page that is missing the very detail you were sent to find.

Available (from Angular's extensions page): Bitly · Link Preview · Message Shortcuts · Pin Message · Rich Media Preview · Save Message · Thumbnail Generation · TinyURL · Voice Transcription · Giphy · Message Translation · Polls · Reminders · Stickers · Stipop · Tenor · Collaborative Document · Collaborative Whiteboard · Disappearing Messages · Chatwoot · Intercom.

Two have a bubble you may reference when customizing, but you still do not mount them yourself: CometChatPollBubbleComponent, CometChatStickerBubbleComponent.

Not available for Angular: end-to-end encryption, live streaming, email replies. They exist for other platforms. Say so plainly rather than improvising.

AI features

Enable in the dashboard (AI section), then place the component you need:

html
<cometchat-smart-replies></cometchat-smart-replies>
<cometchat-conversation-starter></cometchat-conversation-starter>
<cometchat-conversation-summary></cometchat-conversation-summary>

<cometchat-message-list> also emits smartReplyClick and conversationStarterClick when those are enabled, so the built-in surfaces work without extra components. The AI assistant is CometChatAIAssistantChat — no Component suffix.

Features that DO need code

Common pitfalls

  1. Building a feature that is already on — hand-rolled reaction pickers are the classic. Check the "already on" list first.
  2. Assuming every extension is zero-code — 10 of them render no affordance and need CometChat.callExtension(). Equally, do not write code for the auto-rendered ones.
  3. Declaring a feature absent because node_modules has no method for it — extensions have no named SDK method; they go through the generic callExtension(). Check the extension's docs page before saying it is unsupported.
  4. Re-implementing a server-side feature in the browser — localStorage, an in-memory Map, or a local BehaviorSubject where an extension exists. Saved/pinned messages, reminders and shortcuts are stored server-side and are per-user across devices; a browser-local copy does not sync to the user's phone and dies with the cache. If a request is about remembering something about a message, check features.angular-v5.json before writing storage of your own.
  5. Offering a feature Angular does not have — E2E encryption, live streaming, email replies.
  6. Forgetting the dashboard step — the code is right, the feature is off, and it looks broken.
  7. Treating reactions/mentions as extensions — they are core in v5.

Verify it works

The feature appears in a real conversation · you wrote no code for a dashboard-only feature · the dashboard toggle is on for the app the credentials point at.

Explain what you built (REQUIRED close)

Tell the developer what changed, naming the files: the feature you just enabled (and whether it needed a dashboard toggle). Flag anything dev-only as dev-only, and say what you did not touch — this is additive.

Then offer these THREE options as a SELECTABLE choice and WAIT for the pick — never auto-continue (RULES.md §19):

  1. Add another feature → another grow-set feature from features.angular-v5.json that is NEITHER wired NOR already enabled — ASK about dashboard state rather than assuming. Never offer an auto entry (reactions, mentions, receipts, typing, media) — those are core in v5 and already on.
  2. Customize theming → cometchat-angular-v5-customization.
  3. Test it manually → do nothing further; hand back so the user runs it.
