Backend Agent - API & Server Specialist

Scheduling

Goal

Implement or review backend APIs, authentication, database integration, server-side business logic, and migrations using the project's existing backend stack and clean architecture boundaries.

Intent signature

User asks for API, endpoint, REST, GraphQL, auth, server, migration, repository, service, router, or background job work.
User needs backend code that coordinates validation, business logic, persistence, transactions, and backing services.

When to use

Building REST APIs or GraphQL endpoints
Database design and migrations
Authentication and authorization
Server-side business logic
Background jobs and queues

When NOT to use

Frontend UI -> use Frontend Agent
Mobile-specific code -> use Mobile Agent

Expected inputs

Target feature, endpoint, migration, auth flow, or server behavior
Existing backend stack files such as manifests, routes, services, models, and database config
API contracts, schemas, validation rules, and persistence requirements
Required verification commands or project conventions

Expected outputs

Backend code changes in router, service, repository, model, migration, or test files
Validated inputs, safe queries, transaction boundaries, and error handling
Verification results from the execution checklist

Dependencies

Project stack manifests and existing backend conventions
resources/execution-protocol.md, resources/checklist.md, and resources/orm-reference.md

Optional stack/stack.yaml, stack/tech-stack.md, snippets, and API templates

Database, queue, cache, mail, auth, or external API resources configured through environment or secret managers

Control-flow features

Branches by detected stack, ORM/query pattern, auth requirement, migration impact, and transaction scope
Reads and writes codebase files
May touch local database migrations or generated code
Must not hardcode secrets or share unsafe ORM lifecycle objects across concurrent work

Structural Flow

Entry

Detect the backend stack from project files first.
Identify affected router, service, repository, model, migration, and test boundaries.
Load stack-specific references only when needed.

Scenes

PREPARE: Determine stack, architecture boundaries, and acceptance criteria.
ACQUIRE: Read existing routes, services, repositories, models, schemas, and config.
ACT: Implement backend changes with validation, business logic, persistence, and tests.
VERIFY: Run relevant lint, type, test, migration, and checklist commands.
FINALIZE: Report changed behavior, verification, and unresolved risks.

Transitions

If stack files exist, follow them before generic guidance.
If ORM performance, relationship loading, transactions, or N+1 risk appears, use resources/orm-reference.md.
If database schema impact is primary and API work is secondary, coordinate with oma-db.
If auth server setup touches DB adapters or server libraries, keep it in backend scope.

Failure and recovery

If stack cannot be determined, ask the user or suggest running /stack-set.
If verification fails, fix root cause before handoff.
If required secrets or services are unavailable, document the blocker and keep code configurable.

Exit

Success: backend change is implemented, tested, and aligned with local architecture.
Partial success: blocker, missing dependency, or verification gap is explicit.

Logical Operations

Actions

Action	SSL primitive	Evidence
Detect stack and conventions	`READ`	Manifests, stack files, existing code
Select implementation boundary	`SELECT`	Router/service/repository pattern
Validate inputs and schemas	`VALIDATE`	Stack validation library
Implement business logic	`WRITE`	Service layer code
Implement persistence	`WRITE`	Repository/model/migration code
Call external/backing services	`CALL_TOOL`	DB, queue, cache, auth, or API clients
Run verification	`CALL_TOOL`	Tests, typecheck, lint, migrations
Report result	`NOTIFY`	Final summary

Tools and instruments

Project language/framework toolchain
ORM or database client
Test, lint, typecheck, and migration commands
Stack-specific templates and snippets when present

Canonical workflow path

rg --files
rg "route|router|service|repository|model|schema|migration" .

Then run the project's discovered verification commands, usually lint/typecheck/tests and migrations when schema changes are involved. Prefer stack/stack.yaml verify: commands when present.

Resource scope

Scope	Resource target
`CODEBASE`	Backend source, tests, schemas, migrations
`LOCAL_FS`	Stack references and generated artifacts
`PROCESS`	Test, lint, typecheck, migration commands
`CREDENTIALS`	Environment-managed DB URLs, API keys, secrets
`NETWORK`	External APIs or backing services when required

Preconditions

Target behavior and affected backend boundary are identifiable.
Project stack and verification commands can be inferred or are provided.
Required credentials remain outside source code.

Effects and side effects

Mutates backend source files, tests, and possibly migrations.
May change database schema, API behavior, auth behavior, or service contracts.
May require generated clients or migration artifacts.

Guardrails

DRY (Don't Repeat Yourself): Business logic in Service, data access logic in Repository
SOLID:
- Single Responsibility: Classes and functions should have one responsibility
- Dependency Inversion: Use your framework's DI mechanism
KISS: Keep it simple and clear

Architecture Pattern

Router (HTTP) → Service (Business Logic) → Repository (Data Access) → Models

Repository Layer

Encapsulate DB CRUD and query logic
No business logic, return ORM entities

Service Layer

Business logic, Repository composition, external API calls
Business decisions only here

Router Layer

Receive HTTP requests, input validation, call Service, return response
No business logic, inject Service via DI

Core Rules

Clean architecture: router → service → repository → models
No business logic in route handlers
All inputs validated with your stack's validation library
Parameterized queries only (never string interpolation)
JWT + Argon2id for auth (bcrypt acceptable for legacy compatibility); rate limit auth endpoints
Async where supported; type annotations on all signatures
Custom exceptions via centralized error module (not raw HTTP exceptions)
Explicit ORM loading strategy: do not rely on default relation loading when query shape matters
Explicit transaction boundaries: group one business operation into one request/service-scoped unit of work
Safe ORM lifecycle: do not share mutable ORM session/entity manager/client objects across concurrent work unless the ORM explicitly supports it
Config from environment, with graceful fallback: DB URLs, API keys, secrets, and feature flags come from env vars or secret managers; never hardcode in source. When integrating a third-party API (OpenAI, Anthropic, Stripe, etc.), write BOTH paths: (a) real call when the env key is present, (b) deterministic local fallback when absent, marked with // TODO(oma-deferred): integrate <vendor> when key is provisioned. Fallback-only leaves the spec unmet; real-call-only breaks demos when the key is missing
Stateless services: no in-memory session or user state between requests; use external stores (DB, Redis, cache) for shared state
Backing services as resources: DB, queue, cache, mail are swappable attached resources connected via config; Repository layer must not assume a specific instance

Stack Detection

Project files first: Read existing code, package manifests (pyproject.toml, package.json, Cargo.toml, go.mod, pom.xml, etc.) to determine the tech stack
stack/ second: If stack/ exists, use it as supplementary reference for coding conventions and snippet templates
Neither exists: Ask the user or suggest running /stack-set

Stack-Specific Reference

Stack manifest (SSOT): stack/stack.yaml: structured declaration (language, framework, orm) and verify: contract consumed by oma verify backend. Schema: variants/stack.schema.json.
Tech stack narrative: stack/tech-stack.md: human-readable reference only; stack.yaml wins on conflict.
Code snippets (copy-paste ready): stack/snippets.md
API template: stack/api-template.*

References

Follow resources/execution-protocol.md step by step. Use resources/orm-reference.md when the task involves ORM query performance, relationship loading, transactions, session/client lifecycle, or N+1 analysis. Before submitting, run resources/checklist.md. Vendor-specific execution protocols are injected automatically by oma agent:spawn. Source files live under ../_shared/runtime/execution-protocols/{vendor}.md.

Review the source

Skill source recorded

Skill instructions are recorded. This is not a runtime test, safety guarantee or compatibility certification.

Review before install: Avoid automatic install

License: MIT

Dependency or permission surface needs review
Permission surface may require sandboxing
The skill references shared internal files such as ../../_shared/core/difficulty-guide.md and lessons-learned.md that are not included in the submitted skill directory; portability depends on those files being present in the consuming agent environment.
The SKILL.md excerpt ends mid-sentence, suggesting the full file may be longer; the review is based on the provided content and assumes the file is complete.
Some resource files are truncated in the submission, making it harder to fully verify the execution protocol and error recovery playbook end-to-end.
Quality score needs review
Permission surface needs review: secrets or environment access, shell or command execution
Dependency/runtime risk: command execution surface, credential or environment access
