Functions

func NewDevtoolsHandler

func NewDevtoolsHandler(deps DevtoolsHandlerDeps) http.Handler

NewDevtoolsHandler builds all /api/devtools routes.

func Run

func Run(args []string, stdout, stderr io.Writer, version, commit string) int

Run is leather's main entry point. It parses the first argument as a subcommand and dispatches to the appropriate handler, returning an exit code. version and commit are set by -ldflags at build time.

func RunAttach

func RunAttach(args []string, stdout, stderr io.Writer) int

RunAttach connects to a running serve instance and streams pretty-printed DevTools events to stdout.

func RunChat

func RunChat(args []string, stdin io.Reader, stdout, stderr io.Writer) int

RunChat starts an interactive chat session backed by the leather session abstraction (token budget, automatic context summarization). Usage: leather chat [flags]

func RunDoctor

func RunDoctor(args []string, stdout, stderr io.Writer) int

RunDoctor prints the effective configuration with source attribution and redacts secret-bearing values.

Usage: leather doctor [flags]

func RunIngest

func RunIngest(args []string, stdout, stderr io.Writer) int

RunIngest implements the "leather ingest" subcommand. Returns exit code: 0 success, 1 error, 2 usage error.

func RunInit

func RunInit(args []string, stdout, stderr io.Writer) int

RunInit scaffolds a new leather project directory with a config, example agent, and Makefile. Fails closed on existing files unless --overwrite is set.

Usage: leather init [--dir <path>] [--overwrite]

func RunOnce

func RunOnce(args []string, stdout, stderr io.Writer) int

RunOnce loads and executes a single agent definition, then exits. Usage: leather run [flags] <path-to-agent.agent.md>

func RunReplay

func RunReplay(args []string, stdout, stderr io.Writer, version, commit string) int

RunReplay implements `leather replay <file> [serve flags...]` as a thin wrapper around `leather serve --replay <file> --api`. The replay subsystem runs inside the serve loop; exposing a top-level `replay` subcommand makes the entry point discoverable (T6.8).

Usage:

leather replay <snapshot.json> [--addr 127.0.0.1:7749] [other serve flags]
leather replay --live <dir>     [other serve flags]

func RunServe

func RunServe(args []string, stdout, stderr io.Writer, version, commit string) int

RunServe starts the leather scheduler loop and blocks until signalled. It exits cleanly on SIGINT or SIGTERM, draining in-flight jobs first.

func RunSnapshot

func RunSnapshot(args []string, stdout, stderr io.Writer) int

RunSnapshot dispatches to save or restore sub-subcommands.

func RunSnapshotRestore

func RunSnapshotRestore(args []string, stdout, stderr io.Writer) int

RunSnapshotRestore extracts a snapshot archive into the configured state directory.

Usage: leather snapshot restore --input <path> [--force]

func RunSnapshotSave

func RunSnapshotSave(args []string, stdout, stderr io.Writer) int

RunSnapshotSave creates a point-in-time tar.gz archive of runtime state.

Usage: leather snapshot save [--output <path>]

func RunStatus

func RunStatus(args []string, stdout, stderr io.Writer) int

RunStatus prints scheduler state and token budget information.

func RunTestAgent

func RunTestAgent(args []string, stdout, stderr io.Writer) int

RunTestAgent implements the "leather test-agent" subcommand. It loads an agent definition, runs it using a MockLLM (no real LLM calls), prints the turn transcript, and exits 0 on success, 1 on error, 2 on usage error.

Usage: leather test-agent <agent-file> [flags]

--lifecycle <file>            apply a *.lifecycle.yaml before running
--mock-response <text>        LLM response text (default: "mock response")
--tool-response <name>=<text> tool name to response text (repeatable, reserved for future use)
--max-tokens <n>              token budget (default 8192)

func RunValidate

func RunValidate(args []string, stdout, stderr io.Writer) int

RunValidate parses and validates all agent, skill, and worker definition files. Exits 0 if all files are valid, 1 if any have errors, 2 on usage errors.

Output format:

ok:     <name>  (<path>)           — file parsed and schema-clean
error:  <file>: <message>          — parse or semantic error
schema: <file>:  field "<name>": <msg>  — schema violation

func RunVersion

func RunVersion(_ []string, stdout, _ io.Writer, version, commit string) int

RunVersion prints build version and platform information to stdout.

Types

type DevtoolsHandlerDeps

type DevtoolsHandlerDeps struct {
	Bus          *bus.Bus
	Causality    *causality.Engine
	QueueMgr     *queue.Manager
	GetWorkerSup func() *worker.Supervisor
	StartedAt    time.Time
	Version      string
	Commit       string
}

DevtoolsHandlerDeps provides data dependencies for DevTools handlers.
