Description

OpenClaw's Fractal Memory adapter exposed the original seven MCP tools but could not use the newer capture, review, import, and resume workflows. This adds those workflows through agent tools, the authenticated admin API, and the CLI, while preserving compatibility with older servers.

Summary

  • Add fourteen explicitly allowed workflows, preserving document hashes, decision IDs, structured context, and source resource links.
  • Keep writes opt-in and agent approvals enabled by default. Bind approvals to the complete request; enforce mutation permissions and browser CSRF separately from diagnosis/import previews.
  • Support executable arguments for source-built MCP servers, discover supported tools, validate repository readiness, and return actionable protocol/compatibility errors.
  • Prefer upstream bounded context for automatic injection, retain export fallback, and enforce the final OpenClaw context budget.
  • Document setup and add stdio, gateway/client, authorization, and live upstream regression coverage. No new package dependencies.

Type of Change

  • Bug fix
  • New feature
  • Documentation update
  • Tests
  • Breaking change

Validation

  • dotnet restore OpenClaw.Net.slnx
  • dotnet build OpenClaw.Net.slnx --configuration Release --no-restore — zero warnings and errors.
  • dotnet test OpenClaw.Net.slnx --configuration Release --no-build with OPENCLAW_FRACTAL_SOURCE set — 2,964 passed, 0 failed, 10 skipped. Skips are the existing Vault/Nacos live-service tests requiring external services.
  • dotnet run --project samples/OpenClaw.HelloAgent -c Release --no-build — deterministic agent/tool smoke passed.
  • Focused Fractal Memory, memory recall, and Runtime Pulse suite: 61 passed, 0 failed, 0 skipped.
  • Live upstream test against agentqi/fractal-memory@893432e76805070d427f62a0362e5ef3e4847957: all fourteen new workflows plus seven original tools, stale-write rejection, import preview/apply, source links, and automatic context budgeting in a temporary repository.
  • CLI help and invalid-argument smoke checks; git diff --check.

The live test requires a built upstream checkout via OPENCLAW_FRACTAL_SOURCE; it is opt-in in ordinary test runs. NativeAOT compatibility was considered through source-generated serialization and the existing AOT-compatible adapter; a native publish was not run for this PR.

Review Notes

  • I considered NativeAOT compatibility.
  • I considered security posture and unsafe defaults.
  • I updated docs/tests where needed.
  • This PR is scoped and does not mix unrelated changes.

The integration and writes remain disabled by default. Automatic context changes only for enabled integrations whose server advertises memory_context. CLI/admin mutations are explicit operator actions; agent tools use the existing approval policy.

Commercial or Customer-Driven Contribution Disclosure

This adds optional interoperability with the external FractalMem project. No company or customer context was provided with the request. It adds no customer-specific workflows or vendor-exclusive defaults.

Checklist

  • I have read the contributing guidelines.
  • My code follows the project's code style.
  • I have added tests for the feature and failure paths.
  • All executed new and existing tests passed locally; external-service skips are listed above.
  • I have updated the documentation.
  • I have checked input validation and authorization implications.
  • I have checked the relevant maintainer review checklist.
  • I have disclosed the available company/customer context.

Summary by CodeRabbit

  • New Features
    • Expanded Fractal Memory support with 14 workflows for capture, review, context, resume, handoffs, diagnostics, and import.
    • Added opt-in write operations with approval safeguards, hash validation, previews, and audit records.
    • Added CLI workflow commands and administrative API access.
    • Improved context handling with source links, metadata preservation, and legacy export fallback.
  • Documentation
    • Updated setup, compatibility, configuration, workflow, and verification guidance.
  • Bug Fixes
    • Improved availability detection, argument validation, cancellation handling, repository resolution, and error reporting.

📝 Walkthrough

Walkthrough

Fractal Memory now supports fourteen structured workflows through MCP, agent tools, CLI commands, and an admin API. The change adds schema validation, write controls, approval binding, source-link preservation, bounded context, legacy fallback, compatibility documentation, and hermetic and live tests.

Changes

Fractal Memory workflow integration

Layer / File(s) Summary
Workflow contracts and models
src/OpenClaw.Core/Abstractions/..., src/OpenClaw.Core/Memory/..., src/OpenClaw.Core/Models/...
Adds the fourteen-operation allowlist, JSON argument validation, workflow result and resource-link models, MCP argument configuration, and AOT serialization registrations.
MCP provider and context execution
src/OpenClaw.Agent/Memory/FractalMemoryMcpProvider.cs, src/OpenClaw.Core/Memory/ContextBudgetPlanner.cs
The provider discovers advertised tools, validates repository availability, executes workflows, preserves structured data and source links, supports bounded context, and falls back to legacy export.
Agent tools and runtime registration
src/OpenClaw.Agent/Tools/..., src/OpenClaw.Gateway/Composition/...
Adds workflow tools with argument validation, mutation detection, write blocking, approval descriptors, content-bound fingerprints, and runtime registration.
CLI and admin workflow surfaces
src/OpenClaw.Cli/..., src/OpenClaw.Client/OpenClawHttpClient.cs, src/OpenClaw.Gateway/Endpoints/AdminEndpoints.Memory.cs
Adds CLI workflow execution, HTTP client delegation, and an authenticated admin endpoint with validation, mutation authorization, CSRF checks, and mutation auditing.
Compatibility and verification
docs/..., src/OpenClaw.Tests/...
Documents setup, compatibility, workflow behavior, and context fallback. Adds stdio fixtures, gateway tests, workflow tests, and an environment-gated live upstream test.

workflow-provider branch around FractalMemoryWorkflowTool.CreateTools to fail
explicitly if structuredMemoryProvider does not implement
IStructuredMemoryWorkflowProvider; otherwise add the workflow tools as currently
done. Use an InvalidOperationException with a clear diagnostic identifying the
