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 | $0.00185 | $0.02908 |
| Opus 5 | $0.00093 | $0.01454 |
| Sonnet 5 | $0.00037 | $0.00582 |
| Haiku 4.5 | $0.00018 | $0.00291 |
Grade A, and why
jframe-module-design 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.

jframe Module Design
This skill guides you through designing and creating a new module for the jframe Go scaffolding framework. jframe uses a kernel-based modular architecture where every feature is a kernel.Module with a structured lifecycle managed by a dependency injection container.
When to use this skill
- User wants to add a new feature/service to the jframe application
- User asks to create/scaffold/design a new module
- User wants to integrate an external service (database, cache, API, etc.) as a module
Overview of the module system
Every module implements kernel.Module (defined in core/kernel/module.go). The kernel runs modules through 6 sequential lifecycle phases, each receiving a *kernel.Hub that wraps the DI container (inject.Injector) plus a namespaced logger:
Config loading → PreInit → Init → PostInit → Load → Start (goroutine)
↓
Stop (concurrent via WaitGroup)
Modules interact exclusively through the Hub's DI container — they never import each other directly. This is the core decoupling mechanism.
Step 1: Gather requirements
Before writing any code, clarify these with the user:
- What does the module do? — Is it a service client (DB, cache, API), a protocol server (HTTP routes, gRPC), a background worker, or business logic?
- What name should it have? — The
Name()return value determines the YAML config key and log namespace. Convention: camelCase for infrastructure (myDB,rds), descriptive for business modules (users,orders). - Does it need configuration? — External services almost always do. Business modules may or may not.
- What does it produce for other modules? — What will it
Mapinto the DI container? (e.g.,*gorm.DB,*redis.Client, a custom service interface) - What does it consume from other modules? — What will it
Loadfrom the DI container? (e.g.,*jin.Enginefor HTTP routes,*gorm.DBfor data access) - Does it need a long-running goroutine? — Only if it runs a server or background loop.
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.

jframe-module-design is a skill published in the GitHub repository juanjiTech/jframe (5 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 185 tokens to every session and 2,908 once invoked, about $0.0009 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 2026-08-31.
