What it costs to keep this loaded
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 | $0.00075 | $0.03266 |
| Opus 5.5 | $0.00030 | $0.01306 |
| Sonnet 5.5 | $0.00015 | $0.00653 |
| Haiku 4.5 | $0.00007 | $0.00327 |
Grade A, and why
hexagonal-inversify-di 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 2mo 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.
How it starts

Hexagonal + InversifyJS DI Pattern
This monorepo uses Hexagonal architecture (Ports & Adapters) wired with InversifyJS. Every package's role is encoded in its name prefix, and dependency wiring follows a strict, repeatable recipe.
When to Use This Skill
Load this skill when the task involves:
- Creating a new package under
packages/ - Adding or modifying a port (interface + token) in a
core-*package - Implementing a use case inside
core-* - Implementing a driven (secondary) or driving (primary) adapter
- Editing an app composition root (
apps/*/src/services/container.ts,apps/*/src/bootstrap-*.ts,apps/*/src/main.ts) - Any question about
@injectable,@inject,Container, bindings, or scopes in this repo
Architecture Map
| Prefix | Role | May depend on |
|---|---|---|
core-* |
Domain. Use cases + port definitions (input-ports/, output-ports/) |
types, core-utils |
*-driving-* |
Primary adapter. Drives the core inward (e.g. HTTP/MCP/RPC entrypoints) | relevant core-*, types, helper-* |
*-driven-* |
Secondary adapter. Driven by the core outward (DBs, external services, loggers) | relevant core-*, types, helper-* |
helper-* |
Shared utilities/mixins used by adapters | types |
types |
Pure type-only contracts. No DI, no runtime code. | nothing |
Rule of thumb: adapters depend on core-* (where the port lives), never directly on types when a port exists. Core depends only on types and core-utils.
Core Conventions
1. DI library
- InversifyJS +
reflect-metadata - Import
reflect-metadataonce per runtime entrypoint (already handled in existing apps)
2. Dual identifier trick (ports)
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.

hexagonal-inversify-di is a skill published in the GitHub repository ndthanhdev/mcp-browser-kit (55 stars, last pushed 6d ago), licensed MIT. It adds 75 tokens to every session and 3,266 once invoked, about $0.0003 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 2026-08-30.
