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 | $0.00052 | $0.01378 |
| Opus 5.5 | $0.00021 | $0.00551 |
| Sonnet 5.5 | $0.00010 | $0.00276 |
| Haiku 4.5 | $0.00005 | $0.00138 |
Grade A, and why
core 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 1mo ago.
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.

Core - Infrastructure Generation
Generates the core infrastructure that all features depend on.
When to Use This Skill
- After
/initcompletes - Before adding any features or
/auth - Setting up app-wide infrastructure
- User asks to "generate core", "create infrastructure", or "setup theme/router"
What This Skill Creates
lib/app.dart- Root app widget with MaterialApp.routerlib/core/theme/- AppColors, AppTypography, AppThemelib/core/router/- GoRouter configurationlib/core/services/- SecureStorage, SharedPrefs, Supabase, iOS network permissionlib/core/errors/- Typed failures and exceptionslib/core/constants/- App constants, legal URLs, storage keys, debug flagslib/core/network/- Dio client (if custom API)lib/core/navigation/- StatefulShellRoute (if bottom nav)lib/core/providers.dart- Core Riverpod providers
Workflow
Phase 1: Gather Requirements
Use AskUserQuestion to confirm settings from /init:
- Primary Color (hex, from /init or ask)
- Theme Mode (light/dark/both)
- Use Supabase? (from /init)
- Use Custom API? (from /init)
- Bottom Navigation? (yes/no - determines shell creation)
- Privacy Policy URL? (can be placeholder, required before release)
- Terms of Service URL? (can be placeholder, required before release)
Phase 2: Create Directory Structure
mkdir -p lib/core/{constants,errors,network,router,navigation,services,theme,utils,widgets}
mkdir -p lib/features
Phase 3: Generate Files
Copy from reference/ directories and customize:
| Category | Files | Notes |
|---|---|---|
theme/ |
app_colors, app_typography, app_theme | Customize primary color |
services/ |
secure_storage, shared_prefs, ios_network_permission | Always |
services/ |
supabase_service | If Supabase = yes |
network/ |
dio_client | If Custom API = yes |
router/ |
app_router | Customize routes |
navigation/ |
main_shell | If bottom nav = yes |
errors/ |
failures, exceptions | Always |
constants/ |
app_constants, legal_constants, storage_keys, debug_constants | Always |
utils/ |
legal_utils | Always |
| root | providers.dart | Customize based on services |

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.
- 1mo ago First seen · 159 lines · 52 tokens per session scan A e7b3d778b365
core is a skill published in the GitHub repository launch52-ai/flutter-template (2 stars, last pushed 7mo ago), licensed MIT. It adds 52 tokens to every session and 1,378 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-31.
