func BuildCommand ¶

func BuildCommand(agentSessionID, mode string, resume bool, envExports string) string

BuildCommand builds the hermes CLI command string.

agentSessionID is the hermes session ID (Session.AgentSessionID). On resume:

• if non-empty: `hermes --resume <id>`
• if empty: `hermes -c` (continue most-recent)

In both resume branches the command falls back to a fresh `hermes` on non-zero exit — matches codex's pattern for crash/Ctrl-C parity. (Hermes itself exits 0 even on bad ID, so this fallback is purely defensive against crashes during resume.)

envExports, when non-empty, is prepended verbatim as a shell prelude.

func DiscoverSessionID ¶

func DiscoverSessionID(spawnStart time.Time) (string, bool)

DiscoverSessionID polls `hermes sessions list --source cli --limit 10` for a row whose ID-encoded timestamp is at or after spawnStart, and returns the newest match.

Returns ("", false) on timeout, missing binary, or any subprocess error — callers fall through to `hermes -c` semantics, which is strictly less precise but still correct.

func New ¶

func New() agent.Agent

New returns the hermes Agent. Exposed (not just via init) so test code that needs a fresh registry can re-register after agent.Reset().
