What it does

Cometchat Angular V5 Migration is an agent skill from cometchat/cometchat-skills. Upgrade an Angular app from CometChat UI Kit v4 → v5 (@cometchat/chat-uikit-angular ^4 → ^5). Reads the repo's CometChat usage, applies the breaking-change map (deps, composite components removed, bare→Component renames, CometChatThemeService → CSS variables, event inputs → Outputs, DataSource → composition, localization renames), fetches the exhaustive guide, and verifies the build. Triggers: 'upgrade my v4 uikit to v5', 'migrate cometchat angular v4 to v5', 'upgrade @cometchat/chat-uikit-angular to v5'…

Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/migration-guide.md`). Compatibility notes: Angular 17-21; FROM @cometchat/chat-uikit-angular ^4 (4.3.36) → ^5 (5.1.0–5.2.0 verified); @cometchat/chat-sdk-javascript ^4.1.13 (peer)…

It sits in Mobile, covering iOS development, Design systems and Internationalization. It works with CometChat, Angular and npm. The repository describes itself as: Add CometChat chat & messaging and voice & video calls to any React, Next.js, React Native, Angular, Android, iOS, or Flutter project through your AI coding agent. Works with… The licence is MIT.

When your agent uses it

  • Tasks that involve iOS development
  • Tasks that involve Design systems
  • Tasks that involve Internationalization

Example prompts

  • “upgrade my v4 uikit to v5”
  • “migrate cometchat angular v4 to v5”
  • “upgrade @cometchat/chat-uikit-angular to v5”
  • “/cometchat-angular-v5-migration”

Requirements

  • Node.js
  • Compatibility (from SKILL.md): Angular 17-21; FROM @cometchat/chat-uikit-angular ^4 (4.3.36) → ^5 (5.1.0–5.2.0 verified); @cometchat/chat-sdk-javascript ^4.1.13 (peer); @cometchat/cards-angular ^1.0.0 (new peer, undocumented in the official guide); @cometchat/uikit-elements/-resources/-shared removed

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

    Shell commands in SKILL.md call:

    • npm

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

  • Network

    No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

    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

    Angular 17-21; FROM @cometchat/chat-uikit-angular ^4 (4.3.36) → ^5 (5.1.0–5.2.0 verified); @cometchat/chat-sdk-javascript ^4.1.13 (peer); @cometchat/cards-angular ^1.0.0 (new peer, undocumented in the official guide); @cometchat/uikit-elements/-resources/-shared removed

    From compatibility in the SKILL.md frontmatter.

Context cost

Cometchat Angular V5 Migration loads about 1.9k tokens when it runs, and up to ~6.9k if it reads all its reference files. Until then it costs about 151 tokens; SKILL.md has 760 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~151
When it runs · the whole SKILL.md, loaded when a task matches
~1.9k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~6.9k

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 migration upgrade v4 v5 uikit

Ground truth: migrates an Angular app FROM @cometchat/chat-uikit-angular@4 TO @5. v5 target symbols are catalog-verified vs installed 5.1.0; the v4→v5 breaking-change map is BAKED in references/migration-guide.md (distilled from the official "Upgrading From V4" guide + a real v4.3.36→v5.1.0 export diff — 146 genuine removals, 33 bare→Component renames, kept separate). The exhaustive per-component prop table is FETCHED from cometchat-angular-v5-components/references/catalog.md + the docs .md twins. APPEND/transform the user's code — never wipe it; work on a branch and confirm before bulk edits (RULES.md).

Companion skills (read first)

  • cometchat-angular-v5-core — the v5 init/login/render the migrated app lands on. This skill ASSUMES it.
  • cometchat-angular-v5-components — the v5 component catalog (the target names + real inputs/outputs).
  • cometchat-angular-v5-placement — how to rebuild a v4 composite from v5 modules (§2 of the migration guide points here per composite).

Use this skill when

"upgrade my v4 UI Kit to v5", "migrate CometChat Angular v4→v5", "bump @cometchat/chat-uikit-angular to v5". Precondition: the project currently has @cometchat/chat-uikit-angular@4.

Migration workflow (BAKED)

  1. Detect the starting point. Confirm package.json has @cometchat/chat-uikit-angular@4 (already @5 → STOP, nothing to migrate). Note whether the app uses composite components (…WithMessages/…WithDetails), CometChatThemeService, *Style inputs, DataSource/ChatConfigurator, or custom localization keys — each drives a later step. Work on a branch; transform in place, never delete the user's code.
  2. Update dependencies. npm install @cometchat/chat-uikit-angular@5 @cometchat/chat-sdk-javascript@^4.1.13 @cometchat/cards-angular@^1.0.0 then npm uninstall @cometchat/uikit-elements @cometchat/uikit-resources @cometchat/uikit-shared. @cometchat/cards-angular is a genuine new 5.1.0 peer the official guide never mentions — install it or the build fails on a missing peer, not a CometChat error.
  3. Scan the repo for v4 usage. Grep for every symbol in references/migration-guide.md §2 (composites, no-equivalent standalones, DataSource/decorators, the ~35 *Style objects) and §2b (the 33 bare-name renames) — produce the concrete change list before editing anything. A bare name is not automatically "removed"; check §2b first.
  4. Apply the breaking-change map (references/migration-guide.md): §2/§2b symbol removals + renames, §3 theming (CometChatThemeService + *Style → CSS variables + the real ThemeService, not the official guide's own hand-rolled matchMedia example — see the warning in §3), §4 event-input → Output rename, §5 DataSource/ChatConfigurator → MessageBubbleConfigService or "nothing, it's auto-rendered," §6 drop CUSTOM_ELEMENTS_SCHEMA + convert to standalone, §7 optional ChatStateService adoption, §8 localization method renames. The baked map is a closed list, not a prop reference — FETCH the rest (RULES.md § Fetch discipline; never node_modules/**/*.d.ts), routed from cometchat-angular-v5-core/references/docs-map.md: the official guide {DOCS_BASE}/ui-kit/angular/customization/migration-guide.md for anything the map omits; a component's exact inputs/outputs/slots from its own .md twin (Angular has no migration-property-changes page — there is no single prop-diff table); an SDK method for a capability with no v5 component ({SDK_DOCS_BASE}/sdk/javascript/groups-overview.md et al.) — that is where the host-composed group surfaces in step 5 come from.
  5. Rebuild every composite from modules. v5 has no composite components at all — CometChatConversationsWithMessages etc. must become a hand-stitched surface. Use cometchat-angular-v5-placement/references/core-surface.md (1:1) or combined-app.md (tabbed) as the target shape, not a literal prop-for-prop port — the composite's configuration options (which v4 had many of) don't exist in v5; its behavior is what you're reproducing.
  6. Verify. Build/typecheck passes; NO v4 symbols remain (grep references/migration-guide.md §2's full list); every kit component is in its consumer's imports: []; the app renders after init→login resolves (cometchat-angular-v5-core/references/lifecycle.md). Reuse cometchat-angular-v5-core "Verify it works".

Common pitfalls (BAKED)

  • Porting the official guide's own theming example. It shows a hand-rolled matchMedia listener for OS-follow — that predates the real v5 mechanism. ThemeService.initFromPreference() already does this; don't reintroduce v4-era manual theme-tracking code (§3).
  • Treating a bare v4 name as removed when it's only renamed. Check §2b (33 bare→Component renames) before concluding a component is gone — most "missing" names are one word away from their v5 form.
  • Missing @cometchat/cards-angular. Genuinely undocumented in the official migration guide; the install fails on a peer-dependency error that looks unrelated to the migration.
  • Forgetting imports: [] after dropping CUSTOM_ELEMENTS_SCHEMA. v4's schema tolerated unregistered elements; v5's standalone components render nothing, silently if omitted from imports: [] — the single most common v5 failure mode, and migrated code is exactly where it's missed (cometchat-angular-v5-core/SKILL.md).
  • Rebuilding a composite as a literal prop-for-prop port. v4 composites had large configuration surfaces (*Style objects, callback inputs) with no v5 equivalent — port the behavior, not the configuration, using cometchat-angular-v5-placement's real recipes as the target.
  • Assuming every DataSourceDecorator needs MessageBubbleConfigService. Some were registering a built-in extension (polls, stickers, translation) — v5 auto-renders most of those once enabled in the dashboard, with nothing to register (cometchat-angular-v5-features/SKILL.md; verify against needs_stitching in features.angular-v5.json, never assume).

Verify it works

Build/typecheck is green; a repo-wide grep finds NO §2 v4 symbols (composites, CometChatThemeService, DataSource/ChatConfigurator, any *Style object, any bare §2b name unqualified); every kit component is in imports: []; the app renders once init→login resolves; migrated theming follows the OS via ThemeService, not a leftover matchMedia listener. Full per-component prop reference: cometchat-angular-v5-components/references/catalog.md + the docs .md twins.
