Rules

• plugin_loading:

  • discovery_paths: Plugins loaded from: 1. Bundled plugins (node_modules/openclaw*/index.ts) 2. Configured load paths (plugins.load.paths[]) 3. Node modules with @openclaw namespace Plugin must export: definePluginEntry() or defineChannelPluginEntry().

  • lazy_loading: Plugins loaded on-demand (not at startup by default). Trigger: First use or explicit /plugin load command. Exceptions: Critical plugins pre-loaded (auth, memory, context-engine). Benefit: Faster startup, reduced memory footprint.

  • manifest_validation: Every plugin provides manifest: { id, name, description, version, authors, capabilities } Validation: required fields + format checks. Error: plugin rejected if manifest invalid.

• plugin_lifecycle:

  • initialization_sequence: 1. Load module (require/import) 2. Validate manifest (id, version, capabilities) 3. Merge with config (from plugins.entries) 4. Initialize config schema (Zod/JSON Schema) 5. Call onEnable() hook (if defined) 6. Register capabilities with gateway 7. Mark initialized=true Failure at any step: plugin disabled, error logged.

  • enable_disable: Enable: Set enabled=true, call onEnable(), expose capabilities. Disable: Set enabled=false, call onDisable(), hide capabilities. Required plugin disabled: warning logged, may prevent execution. Dynamic enable/disable available via CLI.

  • reload_strategy: On config change: 1. Compare manifest_hash 2. If unchanged: skip reload 3. If changed: unload, reinitialize, reload Preserve auth profiles across reload.

• plugin_configuration:

  • config_schema_validation: Plugin defines configSchema (Zod or JSON Schema). config object validated against schema on load. Errors: detailed path reporting (e.g., “config.deeplink.port”). Invalid config: plugin disabled, error shown.

  • ui_hints: Config schema includes UI hints: { field, type, sensitive, description, ui_type } Respected by: CLI wizard, web config UI, mobile app.

  • nested_configuration: Plugins can have deeply nested config with recursive validation. Path-based access: config.integrations.discord.token.

  • environment_variable_substitution: Config values can reference env vars: “apiKey”: “${MY_API_KEY}” or “${API_URL:-https://default.com}” Substitution: performed during load. Secrets detection: _KEY, _TOKEN, _PASSWORD, _SECRET redacted in logs.

• capability_model:

  • capability_declaration: Plugins declare capabilities: [“chat.send”, “context.read”, “tool.custom”, “event.listen”] Capabilities are strings (provider/type/name format).

  • capability_gating: Tools/features check plugin.capabilities before invocation. Missing capability: tool call rejected with permission error. Prevents plugins from exceeding declared scope.

  • capability_categories: System: memory, context-engine, rag, tool.index Chat: chat.send, chat.receive, chat.edit Tools: tool.* (custom namespaces) Context: context.read, context.inject Events: event.listen, event.emit

• slot_based_plugins:

  • memory_slot: plugins.slots.memory: single plugin controls conversation memory. Only one memory plugin enabled at a time. Alternatives: default (file-based), vector DB, custom. Switching: update config, restart gateway.

  • context_engine_slot: plugins.slots.contextEngine: single plugin provides context building. Builds prompt context from conversation history. Alternatives: default (transcript), RAG, custom.

• plugin_allowlist_denylist:

  • allowlist_behavior: plugins.allow: string[] of allowed plugin IDs. If set: ONLY these plugins can load (whitelist mode). Others: rejected during load.

  • denylist_behavior: plugins.deny: string[] of blocked plugin IDs. If set: these plugins cannot load. Deny takes precedence over allow (safer default).

Outcomes

Plugin_loaded (Priority: 1)

Given:

• plugin_id provided
• plugin_id (system) exists
• plugin module found in search paths

Then:

• set_field target: initialized value: false
• set_field target: manifest_hash value: hash(manifest)
• transition_state field: plugin_state from: unloaded to: loading

Result: Plugin module loaded, manifest validated

Plugin_initialized (Priority: 2)

Given:

• plugin_state (db) eq loading
• configSchema validated against config
• onEnable() hook completed without error

Then:

• set_field target: initialized value: true
• set_field target: enabled value: true
• emit_event event: plugin.enabled
• transition_state field: plugin_state from: loading to: enabled

Result: Plugin enabled, capabilities exposed to gateway

Capability_check (Priority: 3)

Given:

• plugin attempting tool use
• required_capability (input) in declared_capabilities

Then:

• set_field target: capability_allowed value: true

Result: Capability check passed, tool use allowed

Capability_denied (Priority: 3) — Error: CAPABILITY_DENIED

Given:

• required_capability (input) not_in declared_capabilities

Then:

• set_field target: capability_allowed value: false

Result: Capability check failed, tool use denied

Plugin_disabled (Priority: 4)

Given:

• enabled (system) eq false

Then:

• call_service target: external_service
• transition_state field: plugin_state from: enabled to: disabled
• emit_event event: plugin.disabled

Result: Plugin disabled, no longer accessible

AGI Readiness

Goals

Reliable Openclaw Plugin System

Plugin registration, lifecycle management, and capability-based permissions system for extending OpenClaw functionality

Success Metrics:

Metric	Target	Measurement
success_rate	>= 99.5%	Successful operations divided by total attempts
error_recovery_rate	>= 95%	Errors that auto-recover without manual intervention

Constraints:

• availability (non-negotiable): Must degrade gracefully when dependencies are unavailable

Autonomy

Level: supervised

Escalation Triggers:

• error_rate > 5
