The sort shim from the previous commit enforces canonical core ordering at runtime, so ZWSP prefixes are no longer needed. Removing them eliminates the Bun.stringWidth vs terminal-width drift that broke the TUI status bar (#3259).
Drop AGENT_LIST_SORT_PREFIXES and getAgentRuntimeName from agent-display-names; switch all call sites to getAgentDisplayName. getAgentListDisplayName stays as a thin alias for external importers.
Keep stripInvisibleAgentCharacters and the ZWSP regex paths so legacy session state and configs from v3.14.0-v3.16.0 still resolve.

Reverts getAgentDisplayName back to getAgentRuntimeName in the remapper
and default_agent assignment. OpenCode sorts agents by name via
localeCompare, so ZWSP prefixes in the name field are required to
preserve canonical core agent order (sisyphus > hephaestus > prometheus > atlas).
- Replace getAgentRuntimeName with getAgentDisplayName for consistency
- Add stripAgentListSortPrefix helper to normalize agent names
- Strip sort prefixes in subagent-resolver and sync-executor
- Backfill canonical names for core agents when builtin configs omit name
- Update tests to match new behavior
Remap the core agent keys, default agent, and command routing back to\nlist display names so OpenCode's name-based sorting keeps the\ncanonical Sisyphus -> Hephaestus -> Prometheus -> Atlas order.\n\nAlso teach tool config lookups to resolve the prefixed list keys and\nadd regression tests that exercise the real ordering and routing path.
Agent names in the config.agent object (which becomes the /agent API
response) contained invisible Zero-Width Space (U+200B) characters
baked in by getAgentListDisplayName(). These ZWSP prefixes were used
for TUI sort ordering, but they leaked into the public API surface.
Impact: any prompt_async consumer that discovered agent names via the
/agent endpoint and passed them back to prompt_async without manual
ZWSP stripping got silent message drops — the agent name didn't match.
hy-pony's feishu-bridge integration went dark after upgrading to 3.16.0
with no error, no warning, and no indication that invisible Unicode
characters in agent names were the cause.
Fix: switch all four callsites from getAgentListDisplayName() (which
prepends \u200B×N) to getAgentDisplayName() (clean names):
- agent-key-remapper.ts: config keys → display names (was the primary
injection point)
- agent-priority-order.ts: CORE_AGENT_ORDER lookup (must agree with
the keys emitted by the remapper)
- command-config-handler.ts: command agent field normalization
- tool-config-handler.ts: agent config lookup (simplified fallback
chain since the primary lookup is now clean)
Sort ordering is preserved by:
1. JS object insertion order from reorderAgentsByPriority()
2. The injected `order` field (1-4) added by injectOrderField()
getAgentListDisplayName() is marked @deprecated with a link to #3238.
AGENT_LIST_SORT_PREFIXES and stripAgentListSortPrefix() are kept for
any internal callers that strip prefixes from legacy data.
Closes#3238
Populate AGENT_LIST_SORT_PREFIXES for sisyphus/hephaestus/prometheus/atlas
so the TUI agent list renders in canonical order. Update dependent tests
to use getAgentListDisplayName() instead of hardcoded display strings.
