What is jframe-module-dev?

A coding guide for building the inside of an existing jframe module, a Go application component with separate request, business-logic, database, and data-model layers.

It is for implementing handlers, services, data access, models, CRUD operations, HTTP or gRPC routes, dependency wiring, and tests in a jframe module.

It helps keep those layers connected correctly and avoids guessing how to add routes, dependency injection, database operations, and tests.

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	$0.00098	$0.00823
Opus 5.5	$0.00039	$0.00329
Sonnet 5.5	$0.00020	$0.00165
Haiku 4.5	$0.00010	$0.00082

Security

Grade A, and why

jframe-module-dev 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 Development

Implement layers inside an existing module. For new module design/scaffold, use jframe-module-design.

Progressive reading

Need	Read
Default path	This file + `mod/example/`
DAO / transactions	`references/stdao.md`
jin / binding / params	`references/jin-handlers.md`
Load wiring / errors / checklist	`references/wiring.md`
gRPC, settings, testing, DI ops	`references/advanced.md`
Human docs	`docs/module-implementation.md`, `docs/stdao.md`

Do not load every reference up front — open only what the current task needs.

Gold standard

Copy from mod/example/ (Item CRUD, compilable, not in modList by default):

mod/example/
├── mod.go           # Load: db + jin → dao → service → handler → routes
├── model/item.go
├── dao/item.go      # stdao.Std[*model.Item]
├── service/item.go
├── handler/item.go
└── e/e.go

Data flow: handler → service → dao → model. Assemble bottom-up in Load().

Implementation order

model — GORM struct (prefer stdao.Model) + DTOs. See example model/item.go.
dao — stdao.Std[*model.T] + NewXxxDao + Init. Details: references/stdao.md.
service — business rules; return e/ errors.
handler — jin routes. Details: references/jin-handlers.md.
mod.go Load — hub.Load deps, wire layers, register routes. Details: references/wiring.md.

Minimal dao sketch

type ItemDao struct {
    stdao.Std[*model.Item]
}
func NewItemDao(db *gorm.DB) (*ItemDao, error) {
    d := &ItemDao{}
    return d, d.Init(db)
}
// queries: d.GetTxFromCtx(ctx).WithContext(ctx).Where(...).First(...)

Import path: github.com/juanjiTech/jframe/pkg/stdao.

Minimal Load sketch

itemDao, err := dao.NewItemDao(db)
svc := service.NewItemService(itemDao)
h := handler.NewItemHandler(svc)
h.RegisterRoutes(j.Group("/api/<name>"))

Files

What ships with it

4 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.
