Overview ¶

Package harness is the vocabulary of the harnesses a card's child runs under: the one word a route row, a packet and a launch name a harness by. It is a leaf (standard library only) so nova-config's route kind, the sprint's route and nova-swarm's launcher all spell the words from one list.

A harness is known by the name of its program. opencode is the harness every provider row of the providers table launches (pkg/swarm providers.go); claude, codex and grok are the headless harnesses of the heavy tier (the owner, 2026-10-04): subscription logins on one machine, each run as a one-shot child printing its own usage, and the route row names which (docs/SPEC-SWARM.md, the headless harnesses).

const (
	OpenCode = "opencode"

	Codex    = "codex"
	Grok     = "grok"
	Muse     = "muse"
)

The harness words.

View Source

const MuseKeyEnv = "META_API_KEY"

MuseKeyEnv is the member's seat-secret name. It is consumed on stdin, removed from the harness environment, and never passed to tool children.

View Source

const ProviderPrefix = "subscription-"

ProviderPrefix begins the provider word of a headless harness's route.

Variables ¶

View Source

var Headless = []string{Claude, Codex, Grok}

Headless names the subscription harnesses that run one-shot and report usage. Muse is also headless, with a provider key on stdin instead of a subscription.

View Source

var Kinds = []string{OpenCode, Claude, Codex, Grok, Muse}

Kinds is every harness word a route row may carry, in the order a list prints them.

Functions ¶

func IsHeadless ¶

func IsHeadless(kind string) bool

IsHeadless reports whether kind is one of the headless harnesses.

func KindOf ¶

func KindOf(bin string) string

KindOf is the harness a binary is: the headless harness its program name spells (`claude`, `/Users/g/.local/bin/codex`, `grok.exe`), and opencode for any other program, which the providers table launches as it always has.

func MuseArgv ¶ added in v1.2.19

func MuseArgv(bin, model, promptFile string) []string

MuseArgv runs the route's model against the card's prompt file.

func MuseInput ¶ added in v1.2.19

func MuseInput(env []string) (key string, child []string)

MuseInput extracts the provider key while stripping it from the child environment.

func ProviderOf ¶

func ProviderOf(kind string) string

ProviderOf is the provider word the routes of a headless harness carry: `subscription-claude`, `subscription-codex`, `subscription-grok`, and "" for any other kind. A rest is a provider's (internal/sprint route_rest.go), so one word per harness keeps one harness's expired login from resting the other two.

Types ¶

type MuseResult ¶ added in v1.2.19

type MuseResult struct {
	Text    string
	Model   string
	Usage   map[string]int64
	Failure string
	Turns   int
}

MuseResult is the terminal answer and summed provider usage, with absent classes left absent. Failure is the terminal refusal for the existing classifier.

func ReadMuse ¶ added in v1.2.19

func ReadMuse(out []byte) (MuseResult, error)

ReadMuse reads the version-one JSONL envelopes. Model calls, not goal attribution mirrors, own the usage, so each reported call is counted once.
