* Context engine: plumb prompt cache runtime context
Add a typed prompt-cache payload to the context-engine runtime context and populate it from the embedded runner's resolved retention, last-call usage, cache-break observation, and cache-touch metadata. Also pass the same payload through the retry compaction runtime context when a run attempt already has it.
Regeneration-Prompt: |
Expose OpenClaw prompt-cache telemetry to context engines in a narrow,
additive way without changing compaction policy. Keep the public change on
the OpenClaw side only: add a typed promptCache payload to the context-engine
runtime context, thread it into afterTurn, and also into compact where the
existing run loop already has the data cheaply available.
Use OpenClaw's resolved cache retention, not raw config. Use last-call usage
for the new payload, not accumulated retry or tool-loop totals. Reuse the
existing prompt-cache observability result and tracked change causes instead
of inventing a new heuristic. If cache-touch metadata is already available
from the cache-TTL bookkeeping, include it; do not invent expiry timestamps
for providers where OpenClaw cannot know them confidently.
Keep the interface backward-compatible for engines that ignore the new field.
Add focused tests around the existing attempt/context-engine helpers and the
compaction runtime-context propagation path rather than broad new integration
coverage.
* Agents: fix prompt-cache afterTurn usage
Regeneration-Prompt: |
Fix PR #62179 so context-engine prompt-cache metadata uses only the current attempt's usage. The review comment pointed out that early exits could reuse a prior turn's assistant usage when no new assistant message was produced. Restrict the prompt-cache lastCallUsage lookup to assistant messages added after prePromptMessageCount, and fall back to current-attempt usage totals instead of stale snapshot history. Also repair the PR's new context-engine test typings and add a regression test for the stale prior-turn case. Two import-only fixes in doctor-state-integrity and config/talk were already broken on origin/main, but they blocked build/check and the gateway-watch regression harness, so include the minimum unblocking imports as well.
* Agents: document prompt-cache context
* Agents: address prompt-cache review feedback
* Doctor: drop unused isRecord import
* feat(context-engine): add ContextEngine interface and registry
Introduce the pluggable ContextEngine abstraction that allows external
plugins to register custom context management strategies.
- ContextEngine interface with lifecycle methods: bootstrap, ingest,
ingestBatch, afterTurn, assemble, compact, prepareSubagentSpawn,
onSubagentEnded, dispose
- Module-level singleton registry with registerContextEngine() and
resolveContextEngine() (config-driven slot selection)
- LegacyContextEngine: pass-through implementation wrapping existing
compaction behavior for 100% backward compatibility
- ensureContextEnginesInitialized() guard for safe one-time registration
- 19 tests covering contract, registry, resolution, and legacy parity
* feat(plugins): add context-engine slot and registerContextEngine API
Wire the ContextEngine abstraction into the plugin system so external
plugins can register context engines via the standard plugin API.
- Add 'context-engine' to PluginKind union type
- Add 'contextEngine' slot to PluginSlotsConfig (default: 'legacy')
- Wire registerContextEngine() through OpenClawPluginApi
- Export ContextEngine types from plugin-sdk for external consumers
- Restore proper slot-based resolution in registry
* feat(context-engine): wire ContextEngine into agent run lifecycle
Integrate the ContextEngine abstraction into the core agent run path:
- Resolve context engine once per run (reused across retries)
- Bootstrap: hydrate canonical store from session file on first run
- Assemble: route context assembly through pluggable engine
- Auto-compaction guard: disable built-in auto-compaction when
the engine declares ownsCompaction (prevents double-compaction)
- AfterTurn: post-turn lifecycle hook for ingest + background
compaction decisions
- Overflow compaction: route through contextEngine.compact()
- Dispose: clean up engine resources in finally block
- Notify context engine on subagent lifecycle events
Legacy engine: all lifecycle methods are pass-through/no-op, preserving
100% backward compatibility for users without a context engine plugin.
* feat(plugins): add scoped subagent methods and gateway request scope
Expose runtime.subagent.{run, waitForRun, getSession, deleteSession}
so external plugins can spawn sub-agent sessions without raw gateway
dispatch access.
Uses AsyncLocalStorage request-scope bridge to dispatch internally via
handleGatewayRequest with a synthetic operator client. Methods are only
available during gateway request handling.
- Symbol.for-backed global singleton for cross-module-reload safety
- Fallback gateway context for non-WS dispatch paths (Telegram/WhatsApp)
- Set gateway request scope for all handlers, not just plugin handlers
- 3 staleness tests for fallback context hardening
* feat(context-engine): route /compact and sessions.get through context engine
Wire the /compact command and sessions.get handler through the pluggable
ContextEngine interface.
- Thread tokenBudget and force parameters to context engine compact
- Route /compact through contextEngine.compact() when registered
- Wire sessions.get as runtime alias for plugin subagent dispatch
- Add .pebbles/ to .gitignore
* style: format with oxfmt 0.33.0
Fix duplicate import (ControlUiRootState in server.impl.ts) and
import ordering across all changed files.
* fix: update extension test mocks for context-engine types
Add missing subagent property to bluebubbles PluginRuntime mock.
Add missing registerContextEngine to lobster OpenClawPluginApi mock.
* fix(subagents): keep deferred delete cleanup retryable
* style: format run attempt for CI
* fix(rebase): remove duplicate embedded-run imports
* test: add missing gateway context mock export
* fix: pass resolved auth profile into afterTurn compaction
Ensure the embedded runner forwards resolved auth profile context into
legacy context-engine compaction params on the normal afterTurn path,
matching overflow compaction behavior. This allows downstream LCM
summarization to use the intended provider auth/profile consistently.
Also fix strict TS typing in external-link token dedupe and align an
attempt unit test reasoningLevel value with the current ReasoningLevel
enum.
Regeneration-Prompt: |
We were debugging context-engine compaction where downstream summary
calls were missing the right auth/profile context in normal afterTurn
flow, while overflow compaction already propagated it. Preserve current
behavior and keep changes additive: thread the resolved authProfileId
through run -> attempt -> legacy compaction param builder without
broad refactors.
Add tests that prove the auth profile is included in afterTurn legacy
params and that overflow compaction still passes it through run
attempts. Keep existing APIs stable, and only adjust small type issues
needed for strict compilation.
