 | `agent.cache_ttl` | string | `"5m"` | Prompt-cache write TTL policy: `5m` (status quo), `1h` (always request the 1-hour TTL), or `auto` (per session at client-build time: sparse-cadence sessions — persistent crons, wakeup loops, spaced chats — get `1h`; dense sessions stay on `5m`). Per-cron-job override via `cache_ttl` in jobs.yaml. See `nerve/agent/cache_policy.py` |
 | `agent.cache_ttl_excluded_models` | list | `[]` | Model-name substrings that never request the 1h TTL |
 | `agent.agent_teams` | bool | `true` | Set `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1` for the CLI subprocess, which registers the `SendMessage` tool. The Agent tool advertises `SendMessage` for resuming a sub-agent whether or not the flag is set, so with it off the model reaches for a tool that does not exist. Nerve loads no settings files (`setting_sources=[]`), so the env dict is the flag's only route in. Teammates stay opt-in per turn and cost a full context window each; the CLI cannot restore in-process teammates when a session's client is recycled (idle timeout, restart, crash retry) |
+| `agent.claude_plugin_dirs` | list | `[]` | Extra local Claude Code plugin directories, passed to the CLI as `--plugin-dir` on top of plugins auto-discovered from `~/.claude` (`enabledPlugins` whose cache dir ships `.mcp.json`). Each dir must contain `.claude-plugin/plugin.json` and may declare `lspServers` (e.g. gopls feeding compiler diagnostics into edit results), `mcpServers`, commands, agents, or skills. Auto-discovery cannot forward marketplace LSP plugins (their cache dirs carry no manifest) and the CLI runs with `setting_sources=[]`, so this key is the only route in for LSP servers. Dirs without a manifest are skipped with a warning. Like every `agent.*` key, YAML edits land via the full config reload (`nerve reload`) and apply to sessions started after it — the MCP-only reload (`mcp_reload` tool, `POST /api/mcp-servers/reload`) re-reads plugin dirs from the in-memory config |
 | `agent.prompt_rewrite.enabled` | bool | `true` | Offer the first-prompt rewrite feature in the web UI (per-user toggle lives in the composer) |
 | `agent.prompt_rewrite.model` | string | `""` | Model for prompt rewriting (empty = `agent.model`, the chat model) |
 | `agent.prompt_rewrite.max_tokens` | int | `1024` | Max tokens for the rewritten prompt |
