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 | $0.00023 | $0.00818 |
| Opus 5 | $0.00012 | $0.00409 |
| Sonnet 5 | $0.00005 | $0.00164 |
| Haiku 4.5 | $0.00002 | $0.00082 |
Grade A, and why
coding-typescript 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 2d 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.

TypeScript Coding Standards
Naming Conventions
| Element | Convention | Example |
|---|---|---|
| Interfaces | PascalCase (no I prefix) | UserProfile, GameState |
| Types | PascalCase | PlayerId, TileGrid |
| Classes | PascalCase | GameEngine, WorldManager |
| Functions | camelCase | calculateDistance, spawnUnit |
| Variables | camelCase | playerCount, isValid |
| Constants | UPPER_SNAKE_CASE | MAX_PLAYERS, TILE_SIZE |
| Enums | PascalCase | PlayerAction, TileType |
| Enum members | PascalCase | TileType.Grassland |
| React Components | PascalCase | GameBoard, PlayerCard |
| Hooks | camelCase (use prefix) | useGameState, usePlayer |
| Files (components) | PascalCase.tsx | GameBoard.tsx |
| Files (utilities) | camelCase.ts | calculateDistance.ts |
| Files (types) | PascalCase.ts | GameState.ts |
Patterns
Type Safety
- Enable
strict: truein tsconfig.json - Prefer
interfaceovertypefor object shapes - Use
typefor unions, intersections, and computed types - Never use
any— useunknownand narrow with type guards - Use branded types for IDs:
type PlayerId = string & { __brand: 'PlayerId' }
Error Handling
- Use Result pattern or typed error objects
- Never throw strings — throw Error instances
- Handle all promise rejections
- Use try/catch at boundaries only
Imports
- Group: react → external → internal → relative
- One blank line between groups
- Prefer named exports over default exports
- Use path aliases (@/components, @/utils)

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.
- 2d ago First seen · 94 lines · 23 tokens per session scan A 6cf1b9bfd7b3
coding-typescript is a skill published in the GitHub repository savant0x/savant-code (11 stars, last pushed 11d ago), licensed Apache-2.0. It adds 23 tokens to every session and 818 once invoked, about $0.0001 per session on Opus 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 2026-08-30.
