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
Reports from david_66 on Discord: sessions get perceived as 'stuck' when
context usage crosses the 78% threshold. Investigation confirmed two
issues in the preemptive compaction hook:
1. PREEMPTIVE_COMPACTION_TIMEOUT_MS was 120s. While the summarize
request is in flight, tool.execute.after short-circuits via the
compactionInProgress guard. A hung summarize blocked the session
for two full minutes before giving up, which users reasonably
experience as a hang.
2. On failure (timeout or exception) only a log line was emitted. The
user had no visibility into why their session was unresponsive or
why auto-compaction never ran, so a transient upstream error could
silently leave them well above the threshold with no signal.
Fix:
- Reduce timeout 120s -> 60s. Still gives the upstream a generous
window, but caps the worst-case perceived hang at one minute.
- Show a warning toast via ctx.client.tui.showToast whenever the
catch block fires, including the underlying error string so users
can act (retry, manual /compact, or adjust provider).
- Include providerID/modelID in the Compaction failed log entry so
wild failures are easier to correlate to a specific target model.
Two existing failure-path assertions were updated to match the new
log shape and a new test covers the toast notification contract.

discoverInstalledPlugins read scope from installed_plugins.json but
never filtered by it, so project/local scoped Claude Code plugins
leaked into every session regardless of process.cwd().
Add projectPath to PluginInstallation and InstalledPluginEntryV3,
propagate it through v3EntryToInstallation, and introduce
shouldLoadPluginForCwd which reuses shared/contains-path for safe
symlink- and ancestor-aware matching and expands a leading tilde.
user and managed scopes still always load; project and local without
a projectPath are skipped as a safe default.
Covered by 13 new shouldLoadPluginForCwd unit tests (including tilde
expansion against a mocked homedir) and 13 new discoverInstalledPlugins
integration tests spanning v1, v2, and v3 database formats plus the
existing enabledPluginsOverride path.
Fixes#3216
