cipher-type-planner

name	cipher-type-planner
description	Plans the creation or modification of a cipher type (vault item type) across the Bitwarden clients monorepo. Use this skill when a user wants to add a new cipher type, modify an existing cipher type, or asks about what is needed to implement a cipher type. DO NOT invoke for general vault or cipher questions unrelated to adding or changing a cipher type.

Cipher Type Planner

Workflow

Step 1: Gather Requirements

Ask the user the following questions (use AskUserQuestion). Adapt questions based on what the user has already provided.

Required questions:

1. Type name and value - What is the cipher type name and integer value? If the user hasn't specified a value, determine the next available integer by reading the CipherType enum definition.
2. Fields - What are the cipher's properties? Each property must contain:
   • Field name
   • Data type (string, number, boolean)
   • Encryption required?
   • Required
3. Target client ($0) - Which client should this plan focus on? (web, desktop, browser, cli, or all). Shared library changes (libs/common, libs/vault) are always included; $0 controls which apps/* files appear. Skip if already provided as an argument. Default: all.
4. Autofill - Should this type participate in browser autofill? (Currently only Login, Card, and Identity support autofill.) Only ask if $0 is browser or all.
5. Linked fields - Should this type support linked custom fields? If yes, which properties should be linkable?
6. Feature flag - What is the feature flag name?
7. Prerequisites - Have all server and SDK prerequisites been completed? Do not proceed with the plan until the user confirms these are done.

Additional questions:

Ask each of the following. If the engineer does not have an answer, accept "N/A" or "not yet decided" and note it as a gap in the plan.

• Import/export - Should import/export support be included in this plan?
• UI details - Are there specific UI requirements for the form or view sections (e.g., dropdowns, masked fields, copy buttons)?
• Subtitle - What value should the subTitle getter on the view model return? This appears in vault list items.
• Icon - What icon represents this type in the vault? Bitwarden uses bwi- icon classes.
• Organization policy - Does this type appear in the restricted item types policy UI?

Step 2: Enter Plan Mode

After gathering requirements, enter plan mode using EnterPlanMode. Explore the codebase to verify current patterns and file locations. Use the SshKey cipher type (value 5) as the canonical reference for implementation patterns.

Key files to inspect for patterns:

• libs/common/src/vault/enums/cipher-type.ts - Enum definition
• libs/common/src/vault/models/api/ssh-key.api.ts - API model pattern
• libs/common/src/vault/models/data/ssh-key.data.ts - Data model pattern
• libs/common/src/vault/models/domain/ssh-key.ts - Domain model pattern
• libs/common/src/vault/models/view/ssh-key.view.ts - View model pattern
• libs/common/src/models/export/ssh-key.export.ts - Export model pattern
• libs/common/src/vault/models/domain/cipher.ts - Container switch patterns
• libs/vault/src/cipher-form/components/sshkey-section/ - Form component pattern
• libs/vault/src/cipher-view/sshkey-sections/ - View component pattern

Step 3: Build the Plan

Write a comprehensive plan to the plan file. The plan MUST include all sections below.

---

Plan Output Format

1. Overview

• Cipher type name:
• Integer value:
• Feature flag:
• Minimum client version:
• Fields: Table of all fields with name, type, encrypted (yes/no), required (yes/no)
• Supports autofill: Yes/No
• Supports linked fields: Yes/No

2. Clients - New Files to Create

List every file that needs to be created, with the full path and a brief description. Organize by layer:

Model stack:

• libs/common/src/vault/models/api/<type>.api.ts - API response shape
• libs/common/src/vault/models/data/<type>.data.ts - Serializable storage format
• libs/common/src/vault/models/domain/<type>.ts - Encrypted business object
• libs/common/src/vault/models/domain/<type>.spec.ts - Domain model tests
• libs/common/src/vault/models/view/<type>.view.ts - Decrypted view for UI

Export (if import/export is included):

• libs/common/src/models/export/<type>.export.ts - Export model

UI components:

• libs/vault/src/cipher-form/components/<type>-section/ - Form section component (TS, HTML, spec)
• libs/vault/src/cipher-view/<type>-sections/ - View section component (TS, HTML)

3. Clients - Existing Files to Modify

List every file that needs modification, organized by concern. For each file, describe the specific change needed.

Core enum:

• libs/common/src/vault/enums/cipher-type.ts - Add <Type>: <N> to CipherType
• libs/common/src/vault/enums/cipher-type.spec.ts - Update tests

Container switches (add case for new type):

• libs/common/src/vault/models/data/cipher.data.ts - Constructor
• libs/common/src/vault/models/domain/cipher.ts - Constructor, decrypt(), toCipherData(), fromJSON(), toSdkCipher(), fromSdkCipher()
• libs/common/src/vault/models/view/cipher.view.ts - item getter, fromJSON(), fromSdkCipherView(), getSdkCipherViewType(), toSdkCipherView()
• libs/common/src/vault/models/request/cipher.request.ts - Constructor
• libs/common/src/vault/models/response/cipher.response.ts - Constructor
• libs/common/src/vault/services/cipher.service.ts - encryptCipherData()

Export (if import/export is included):

• libs/common/src/models/export/cipher.export.ts - toView(), toDomain(), build()

SDK integration:

• libs/common/src/vault/models/domain/cipher-sdk-mapper.ts - Record mapper
• Domain and view model SDK methods (toSdk*/fromSdk*)

UI wiring:

• libs/vault/src/cipher-form/components/cipher-form.component.ts - Import and wire section
• libs/vault/src/cipher-form/components/cipher-form.component.html - Add section template
• libs/vault/src/cipher-view/cipher-view.component.ts - Import and wire section
• libs/vault/src/cipher-view/cipher-view.component.html - Add section template
• libs/common/src/vault/icon/build-cipher-icon.ts - Add icon case

Vault filters (CRITICAL — without these, ciphers won't appear in the vault list):

All vault filter files must be feature-flag-gated so the new type only appears when the flag is enabled. Use ConfigService.getFeatureFlag$() with combineLatest to filter the type out of arrays when the flag is off.

Always included (shared):

• libs/vault/src/services/vault-filter.service.ts - CRITICAL: Add type to buildCipherTypeTree() allTypeFilters array. Without this, ciphers of the new type will not appear in the vault sidebar or list.
• libs/vault/src/models/filter-function.ts - Add filter case for the new type
• libs/angular/src/vault/components/vault-items.component.ts - Feature-flag-gate empty state type buttons

Include if $0 is web or all:

• apps/web/src/app/vault/individual-vault/vault-filter/components/vault-filter.component.ts - Add to allTypeFilters, searchPlaceholder, and feature-flag-gate in buildAllFilters()
• apps/web/src/app/admin-console/organizations/collections/vault-filter/vault-filter.component.ts - Feature-flag-gate in buildAllFilters()

Include if $0 is desktop or all:

• apps/desktop/src/vault/app/vault-v3/vault-filter/filters/type-filter.component.ts - Add ConfigService, combineLatest with feature flag

Include if $0 is browser or all:

• apps/browser/src/vault/popup/services/vault-popup-list-filters.service.ts - Add ConfigService, feature-flag-gate cipherTypes

New item menus (feature-flag-gated):

Always included (shared):

• libs/common/src/vault/types/cipher-menu-items.ts - Add menu item entry for new type
• libs/vault/src/components/new-cipher-menu/new-cipher-menu.component.ts - Add canCreate<Type> = input(false) signal, gate in cipherMenuItems observable

Include if $0 is web or all:

• apps/web/src/app/vault/individual-vault/vault-header/vault-header.component.ts - Add canCreate<Type>$ observable from feature flag
• apps/web/src/app/vault/individual-vault/vault-header/vault-header.component.html - Bind [canCreate<Type>] to <vault-new-cipher-menu>

Include if $0 is browser or all:

• apps/browser/src/vault/popup/components/vault/new-item-dropdown/new-item-dropdown.component.ts - Add ConfigService, combineLatest with feature flag

Localization (add i18n keys):

Include only locale files for $0. If $0 is all, include all three:

• apps/web/src/locales/en/messages.json (web)
• apps/desktop/src/locales/en/messages.json (desktop)
• apps/browser/src/_locales/en/messages.json (browser)

Linked fields (if applicable):

• libs/common/src/vault/enums/linked-id-type.enum.ts

Autofill (if applicable — only if $0 is browser or all):

• List relevant autofill files from apps/browser/src/autofill/ only if the type supports autofill

Restricted item types (if applicable):

Restricted item type enforcement is used across all clients. Include files for $0:

Always included (shared):

• libs/common/src/vault/services/vault-settings/vault-settings.service.ts - Restricted types service

Include if $0 is web or all:

• apps/web/src/app/admin-console/organizations/policies/policy-edit-definitions/restricted-item-types.component.ts - Policy configuration UI
• apps/web/src/app/admin-console/organizations/policies/policy-edit-definitions/restricted-item-types.component.html

Include if $0 is browser or all:

• apps/browser/src/vault/popup/components/vault/item-more-options/item-more-options.component.ts - Restricted type checks

Include if $0 is cli or all:

• apps/cli/src/vault/create.command.ts - Restricted type checks
• apps/cli/src/commands/list.command.ts - Restricted type checks
• apps/cli/src/commands/get.command.ts - Restricted type checks

4. Localization Keys

List all i18n keys that need to be added. At minimum:

• Type label
• Field labels for each type-specific field

5. Tests

List all test files that need to be created or updated:

• libs/common/src/vault/enums/cipher-type.spec.ts
• libs/common/src/vault/models/domain/cipher.spec.ts
• libs/common/src/vault/models/domain/<type>.spec.ts (new)
• libs/common/src/vault/models/view/cipher.view.spec.ts
• libs/common/src/vault/services/cipher.service.spec.ts
• libs/common/src/vault/services/cipher-sdk.service.spec.ts
• libs/common/src/vault/icon/build-cipher-icon.spec.ts
• libs/common/src/models/export/cipher.export.spec.ts
• libs/vault/src/cipher-form/components/cipher-form.component.spec.ts
• libs/vault/src/cipher-view/cipher-view.component.spec.ts
• Form section component spec (new)

6. Recommended Implementation Order

Recommended implementation order, customized for this specific type. Only include steps relevant to $0 (shared steps are always included):

1. Core enum addition (shared)
2. Feature flag registration (shared)
3. Model stack (API, Data, Domain, View, Export if applicable) (shared)
4. Container switch updates (shared)
5. SDK bindings (toSdk*/fromSdk*) (shared)
6. Localization keys ($0)
7. Shared UI (icon, menu items) (shared)
8. Vault filters with feature flag gating — CRITICAL for ciphers to appear (shared + $0)
9. New item menus with feature flag gating (shared + $0)
10. Per-app UI (form section, view section) (shared)
11. Context menu / copy actions — see Section 8 (shared + $0)
12. CLI (only if $0 is cli or all)
13. Autofill (only if $0 is browser or all)
14. Tests (shared + $0)

7. Risks and Considerations

• Cross-repo coordination requirements
• Feature flag rollout strategy
• Backward compatibility concerns
• Any fields that need special encryption handling (reminder: no new encryption logic in clients)
• Performance considerations for large vaults
• i18n key reuse - Before adding new locale keys, check whether existing keys already have the desired display value. If an existing key has the same message text, reuse it instead of creating a duplicate. Only create new keys when no existing key matches.

8. Context Menu / Copy Actions

Each cipher type can expose copiable fields in the vault list item context menus (right-click / more menu). Include only the sections relevant to $0.

Core Infrastructure (always included)

File	What to add
libs/vault/src/services/copy-cipher-field.service.ts	Add field names to the CopyAction type union. Add entries to the CopyActions record with typeI18nKey (i18n key for the toast message), protected (whether it requires password re-prompt), and optional event (for event collection).
libs/common/src/vault/utils/cipher-view-like-utils.ts	Add cases to hasCopyableValue() that check whether the cipher has a non-empty value for each copiable field.

Browser (include if $0 is browser or all)

File	What to add
apps/browser/src/vault/popup/components/vault/item-copy-action/item-copy-actions.component.ts	Add a singleCopyable<Type> getter (for single-field quick copy button), a has<Type>Values getter, and a getNumberOf<Type>Values() method. Follow the Card pattern.
apps/browser/src/vault/popup/components/vault/item-copy-action/item-copy-actions.component.html	Add a section using @if syntax (NOT *ngIf) with the single/multi field pattern.

Web (include if $0 is web or all)

File	What to add
apps/web/src/app/vault/components/vault-items/vault-cipher-row.component.ts	Add is<Type>Cipher and hasVisible<Type>Options getters. Add hasVisible<Type>Options to the showMenuDivider check.
apps/web/src/app/vault/components/vault-items/vault-cipher-row.component.html	Add copy buttons using @if syntax with appCopyField directive.

Desktop (include if $0 is desktop or all)

File	What to add
apps/desktop/src/vault/app/vault-v3/vault-items/vault-cipher-row.component.ts	Add a CipherType.<Type> case to the copyFields computed signal, returning CopyFieldConfig[] entries. This is the most modern pattern — uses a computed signal rather than getters.

Critical Warnings

• CLI has no copy menu UI — do not add copy-related i18n keys to the CLI locale.
• Only expose fields that should be copiable — not every cipher field needs a copy action. Check with product requirements for which fields get copy buttons.
