What is jframe-module-design?

A guide for designing and scaffolding modules in jframe, a Go framework that organizes application features as separate components with defined startup and shutdown stages.

Use it when creating a jframe module, adding a feature or external service, defining configuration, planning dependencies, or mapping the module's lifecycle.

It helps you structure new features and services without making modules depend directly on one another. It also clarifies how configuration, dependency injection, startup, and stopping fit together.

Token cost

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	$0.00079	$0.00631
Opus 5.5	$0.00032	$0.00252
Sonnet 5.5	$0.00016	$0.00126
Haiku 4.5	$0.00008	$0.00063

Security

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 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.

jframe Module Design

Plan and scaffold a new kernel.Module. For writing handler/dao/service code after the skeleton exists, switch to jframe-module-dev.

Progressive reading

Need	Read
Default	This file
DI / lifecycle detail	`references/di-and-lifecycle.md`
Hand-written mod.go template	`references/module-template.md`
Shared Load types	`docs/di-reference.md`
Filled CRUD gold standard	`mod/example/`

Steps

1. Requirements

Name (Name() → YAML key), Config?, Map outputs?, Load inputs?, long-running Start?, HTTP vs worker vs infra client.

2. Lifecycle

Pick only needed phases. Common:

Infra client: Config + PreInit (Map) + Init + Stop
HTTP API: Load (Load jin + DB, routes)
Worker: Load/PostInit + Start + Stop

Details: references/di-and-lifecycle.md.

3. Config

Struct with both yaml and mapstructure tags; Config() any { return &m.config }.

4. DI plan

Map in PreInit with pointers; Load in Load/Init+ from docs/di-reference.md. Modules must not construct peers' clients — only Hub. Importing a type package for Load is fine.

5. Scaffold

go run . create -n <moduleName>

Copies mod/example/ (Item CRUD + pkg/stdao), replaces example → <moduleName>, skips embed.go. Rename types/routes to the domain. Drop unused layers for infra-only modules.

6. Register

Add &<moduleName>.Mod{} to cmd/server/modList/list.go. Same-phase order matters if B.PreInit Loads what A.PreInit Maps.

7. Config YAML

Add section under Name(), or go run . config.

Implement layers with jframe-module-dev (start from generated code / mod/example).

Checklist

Embeds UnimplementedModule; var _ kernel.Module = (*Mod)(nil)
Config dual tags; Map/Load pointers + error checks
Stop: defer wg.Done()
In modList + config defaults

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
