What is ambient-api-server?

A project guide for the Ambient API Server, a Go service that provides REST and gRPC interfaces for platform resources and plugins.

Use it when adding or changing API resources, REST endpoints, gRPC services, OpenAPI definitions, or plugins in the Ambient API Server.

It explains the required structure for resource plugins and identifies the OpenAPI file as the source for generated API code, helping prevent inconsistent changes.

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	$0.00000	$0.00860
Opus 5.5	$0.00000	$0.00344
Sonnet 5.5	$0.00000	$0.00172

Security

Grade A, and why

ambient-api-server 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.

What This Skill Knows

You are working on the Ambient API Server — a Go REST + gRPC server built on the rh-trex-ai framework. It serves the Ambient Platform's resource API under /api/ambient/v1/.

Plugin System (critical)

Every resource kind is a self-contained plugin in plugins/<kind>/. The 8-file structure is mandatory:

plugins/<kind>/
  plugin.go      # route + gRPC registration
  model.go       # GORM DB struct
  handler.go     # HTTP handlers
  service.go     # business logic
  dao.go         # DB layer
  presenter.go   # model → API response
  migration.go   # DB schema
  mock_dao.go    # test mock
  *_test.go      # table-driven tests

Generate scaffold: go run ./scripts/generator.go --kind Foo --fields "name:string,status:string"

OpenAPI is the source of truth

openapi/openapi.yaml
  → make generate → pkg/api/openapi/  (DO NOT EDIT)
  → ambient-sdk make generate → all SDKs

Never edit pkg/api/openapi/ files — they are generated from openapi/openapi.yaml.

gRPC

Protos: proto/ambient/v1/
Stubs: pkg/api/grpc/ambient/v1/ (generated)
Auth: pkg/middleware/bearer_token_grpc.go
Watch streams: server-side streaming RPCs — emit AG-UI events to clients
Ownership bypass: when JWT username not in context (test tokens), skip per-user ownership check

Environments

`AMBIENT_ENV`	Auth	DB	Use for
`development`	disabled	localhost:5432	local `make run`
`integration_testing`	mock	testcontainer (ephemeral)	`make test`
`production`	JWT required	cluster Postgres	deployed

Test setup

systemctl --user start podman.socket
export DOCKER_HOST=unix:///run/user/$(id -u)/podman/podman.sock
cd components/ambient-api-server && make test

Runbook: Add a New API Resource

Define schema in openapi/openapi.yaml
Run make generate (updates Go stubs)
go run ./scripts/generator.go --kind MyResource --fields "..."
Implement service.go and dao.go business logic
Write table-driven tests in *_test.go
Run make test — all green
Run make generate in ambient-sdk to propagate to SDKs
Run make build in ambient-cli to update CLI

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.

ambient-api-server is a skill published in the GitHub repository ambient-code/platform (131 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 860 tokens. 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.
