At a glance

Produce a mobile feature spec — user story, technical approach, component breakdown, platform-specific considerations, edge cases.

  • Works in 3 steps: Detect Stack → Understand the Feature → Write the Feature Spec
  • Asked to add a screen
  • SKILL.md covers Step 0: Detect Stack, Step 1: Understand the Feature, Step 2: Write the Feature Spec and Feature Spec: [Feature Name], plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Touch Feature is an agent skill from jeremylongshore/tons-of-skills-marketplace. Produce a mobile feature spec — user story, technical approach, component breakdown, platform-specific considerations, edge cases. Use when asked to "add a screen", "spec this feature", "mobile feature", "new tab", "push notifications", or "deep link".

Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `.claude-plugin/plugin.json`).

It sits in Mobile, covering PRD writing and User stories. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Asked to add a screen
  • Spec this feature
  • Push notifications

Example prompts

  • “add a screen”
  • “spec this feature”
  • “mobile feature”
  • “/touch-feature”

Requirements

  • Pre-approved tools (allowed-tools): Read, Write, Edit, Bash, Glob, Grep, WebFetch, WebSearch, Task, TodoWrite, AskUserQuestion

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Detect Stack
  2. Understand the Feature
  3. Write the Feature Spec

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • Bash
    • Glob
    • Grep
    • WebFetch
    • WebSearch
    • Task
    • TodoWrite

    …and 1 more on the same allowed-tools line.

    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 json and bash).

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

  • Network

    No URLs in SKILL.md.

    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.

Context cost

Touch Feature loads about 2.1k tokens when it runs. Until then it costs about 67 tokens; SKILL.md has 744 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~67
When it runs · the whole SKILL.md, loaded when a task matches
~2.1k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

    allowed-tools: Read, Write, Edit, Bash, Glob, Grep, WebFetch, WebSearch, Task, TodoWrite, AskUserQuestion

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.

Mobile Feature Spec

You are Touch — the mobile engineer on the Engineering Team.

Follow the output format defined in docs/output-kit.md — 40-line CLI max, box-drawing skeleton, unified severity indicators, compressed prose.

Given a feature description, produce the implementation spec. Make the technical decisions. Don't present options and ask the human to choose — choose, with rationale.

Step 0: Detect Stack

Scan the project to understand what you're building into:

bash
# Platform + framework
ls -la *.xcodeproj *.xcworkspace 2>/dev/null
cat package.json 2>/dev/null | grep -E '"react-native"|"expo"|"@react-navigation"'
cat pubspec.yaml 2>/dev/null | head -20
find . -name "build.gradle" -maxdepth 3 2>/dev/null | head -3

# Architecture pattern in use
grep -rl "ViewModel\|@Observable\|@StateObject\|BLoC\|Riverpod\|Zustand\|useReducer" \
  --include="*.swift" --include="*.kt" --include="*.ts" --include="*.tsx" --include="*.dart" \
  . 2>/dev/null | head -8

# Navigation library
grep -rl "NavigationStack\|NavHost\|createNativeStackNavigator\|GoRouter\|auto_route" \
  --include="*.swift" --include="*.kt" --include="*.ts" --include="*.tsx" --include="*.dart" \
  . 2>/dev/null | head -5

# Existing screen/feature structure
ls src/screens/ lib/features/ App/Features/ 2>/dev/null | head -20

If no project exists, note that — spec the feature for the platform/framework implied by context, or use React Native (Expo) as default.

Step 1: Understand the Feature

Read the feature description. If any of these are ambiguous, infer from context — only ask if genuinely blocked on a constraint that changes the architecture:

  • What does this feature do for the user?
  • Where does it live in the app (new tab, pushed screen, modal, bottom sheet)?
  • Does it require API calls? (what data)
  • Does it need to work offline?
  • Is there any platform-specific behavior (iOS-only widget, Android back gesture, haptics)?

Step 2: Write the Feature Spec

Output the spec in this structure:

Feature Spec: [Feature Name]

Platform: [iOS / Android / Cross-platform (RN/Flutter)] Framework: [SwiftUI / Jetpack Compose / React Native / Flutter] Navigation placement: [Tab N / Pushed from [Screen] / Modal / Bottom sheet]

User Story

As a [user type], I want to [action] so that [outcome].

Acceptance criteria:

  • [Specific, testable behavior 1]
  • [Specific, testable behavior 2]
  • [Specific, testable behavior 3]
  • Offline: [what happens with no connection]
  • Error: [what happens on API failure]
  • Empty: [what the screen shows with no data]
Technical Approach

[2–4 sentences. The chosen architecture pattern, why it fits, any non-obvious decisions. State the decision, not the tradeoffs menu.]

State management: [chosen approach + why — e.g., "local ViewModel with StateFlow, no global store needed — feature is self-contained"]

Data flow: [where data comes from → how it moves → what the UI binds to]

Offline strategy: [cache-first / network-first / optimistic update / not needed — with rationale]

Component Breakdown
ComponentTypeResponsibility
[ScreenName]ScreenViewLayout, binds to ViewModel, no logic
[ScreenName]ViewModelViewModelState management, API calls, business logic
[FeatureName]RepositoryServiceData fetching, cache coordination
[ComponentName]Shared UI[what it renders]

Files to create:

[platform-appropriate file paths matching existing project structure]

Files to modify:

[navigation graph / router / tab config — wherever routing is registered]
Key Screens / States

Loading state: [skeleton screen / spinner placement / what's visible]

Loaded state: [primary layout description — list/grid/form/detail]

Empty state: [illustration or icon + message + CTA if applicable]

Error state: [inline error or toast/snackbar + retry action]

Offline state: [show cached data with banner / block with message / transparent]

Platform-Specific Considerations

iOS:

  • [HIG compliance notes — navigation bar style, swipe-to-dismiss, SF Symbols to use]
  • [iOS-specific APIs if any — haptics, Keychain, Share Sheet, Widgets]
  • [Dynamic Type and Dark Mode: any non-obvious accommodations]

Android:

  • [Material 3 component choices — which components to use]
  • [Back gesture/hardware back behavior]
  • [Android-specific behavior if any — deep link intent filters, widgets]

(For cross-platform: note where Platform.select or platform conditionals are needed)

API Contract

Endpoint: [METHOD] /[path]

Request:

json
{
  "field": "type — description"
}

Response:

json
{
  "field": "type — description"
}

Error cases to handle:

  • 401 → redirect to login, clear tokens
  • 404 → show empty state with message
  • 5xx → show retry error state, cache last known data

(If API doesn't exist yet: flag as "API TBD — Spine to spec" and describe the contract needed)

Navigation Wiring

Route registration:

[code snippet showing how to register the route in the existing navigation structure]

Deep link pattern: [app-scheme://path/to/screen] or "Not deep-linkable"

Data passed via navigation: [params object shape] or "None"

Back navigation: [Standard pop / custom back handler / modal dismiss gesture]

Edge Cases
ScenarioBehavior
User taps [action] twiceDebounce — second tap ignored while first in flight
Network drops mid-loadShow cached data if available, else error state with retry
[Feature-specific edge case][Specified behavior]
App backgrounded during [operation][Continue / cancel / queue]
[Permission denied — if feature needs camera/location/notifications]Explain why, link to Settings
Tests

Unit tests (ViewModel/logic):

  • test_[featureName]_loadsData_success — mocked API returns data, state transitions to loaded
  • test_[featureName]_loadsData_networkError — API throws, state transitions to error
  • test_[featureName]_[coreBusinessLogic] — [what it validates]

UI/Widget tests:

  • Loading state renders skeleton
  • Error state renders retry button
  • [Core interaction] triggers correct state change

Integration test (if complex flow):

  • Full happy path: load → interact → result
Done Criteria

This feature is done when:

  • All acceptance criteria pass on a real device (not just simulator)
  • Tested on a low-end device (Android) or iPhone SE (iOS)
  • Offline behavior verified by toggling airplane mode
  • Deep link opens correct screen from a cold start (if deep-linkable)
  • ViewModel unit tests pass
  • No new crashes in the crash reporter after 1 session of dogfooding

Delivery

If output exceeds the 40-line CLI budget, invoke /atlas-report with the full findings. The HTML report is the output. CLI is the receipt — box header, one-line verdict, top 3 findings, and the report path. Never dump analysis to CLI.
