PR #60698: feat: inject per-agent requestMetadata into Bedrock calls (#60602)

Description (problem / solution / changelog)

Summary

Describe the problem and fix in 2–5 bullets:

• Problem: When running multiple agents on Amazon Bedrock, all ConverseStream API calls go through the same IAM role with no distinguishing metadata. AWS Cost Explorer cannot attribute costs to individual agents.
• Why it matters: Multi-agent setups (e.g., 6 agents sharing one EC2 instance) have no way to build per-agent cost dashboards, budgets, or alerts. Users must resort to fragile monkey-patching workarounds.
• What changed: Automatically injects openclaw:agentId and openclaw:agentName into the requestMetadata field of every Bedrock stream call when the provider is amazon-bedrock. The @mariozechner/pi-ai library already supports passing requestMetadata through to ConverseStream.
• What did NOT change (scope boundary): No changes to non-Bedrock providers. No changes to existing function signatures, config schema, or public API. No changes to test files. Single file change only (src/agents/pi-embedded-runner/extra-params.ts).

Linked Issue/PR

• Related: N/A
• This PR fixes a bug or regression

Root Cause (if applicable)

N/A — This is a new feature, not a bug fix.

Regression Test Plan (if applicable)

N/A — New feature. No existing behavior is modified.

• If no new test is added, why not: The createStreamFnWithExtraParams function is a private helper that wraps the stream function. The injected requestMetadata is a pass-through to the AWS SDK via pi-ai and cannot be easily asserted without mocking the full Bedrock stream pipeline. The feature is guarded by a provider check (provider === "amazon-bedrock") and an agentId check, so it cannot affect non-Bedrock providers. A future integration test with a Bedrock endpoint would be the appropriate coverage level.

User-visible / Behavior Changes

• When using Amazon Bedrock as the model provider in a multi-agent setup, each ConverseStream API call now includes requestMetadata with openclaw:agentId and (when configured) openclaw:agentName.
• This metadata appears in AWS CloudTrail invocation logs and can be used to group costs in AWS Cost Explorer.
• No config changes required — injection is automatic.
• No impact on non-Bedrock providers.

Diagram (if applicable)

Before:
[Agent A] -> [Gateway] -> [Bedrock ConverseStream] (no metadata)
[Agent B] -> [Gateway] -> [Bedrock ConverseStream] (no metadata)
AWS Cost Explorer: all calls appear as one bucket

After:
[Agent A] -> [Gateway] -> [Bedrock ConverseStream] (requestMetadata: {agentId: "a", agentName: "Agent A"})
[Agent B] -> [Gateway] -> [Bedrock ConverseStream] (requestMetadata: {agentId: "b", agentName: "Agent B"})
AWS Cost Explorer: costs can be grouped by openclaw:agentId or openclaw:agentName

Security Impact (required)

• New permissions/capabilities? No
• Secrets/tokens handling changed? No
• New/changed network calls? No — same Bedrock API calls, just with additional non-sensitive metadata fields
• Command/tool execution surface changed? No
• Data access scope changed? No
• If any Yes, explain risk + mitigation: N/A

Repro + Verification

Environment

• OS: Ubuntu (Linux, Inspiron 14)
• Runtime/container: Node.js v24.14.1, pnpm
• Model/provider: Amazon Bedrock (claude-sonnet-4-5, claude-opus-4-6)
• Integration/channel (if any): Multi-agent gateway setup
• Relevant config (redacted):

{
  "agents": {
    "list": [
      { "id": "billing", "name": "Billing Bot" },
      { "id": "support", "name": "Support Agent" }
    ]
  }
}

Steps

1. Configure OpenClaw with multiple agents and Amazon Bedrock as the model provider
2. Send messages through different agents
3. Check AWS CloudTrail for ConverseStream events

Expected

• Each ConverseStream event in CloudTrail includes requestMetadata with openclaw:agentId and openclaw:agentName matching the agent that initiated the call

Actual

• Before this change: no requestMetadata present on any Bedrock calls
• After this change: metadata is injected automatically

Evidence

• Trace/log snippets

Type-checked with npx tsc --noEmit — no errors in the changed file. With --verbose gateway logging, the debug line creating streamFn wrapper with params: {"requestMetadata":{"openclaw:agentId":"...","openclaw:agentName":"..."}} confirms injection.

Note: Pre-existing build errors in compact.ts and setup.ts (contextTokens property) are unrelated to this change and exist on the main branch.

Human Verification (required)

• Verified scenarios:
  • Type-checked the changed file with tsc --noEmit — no type errors
  • Verified boundary tests pass (13 files, 77 tests)
  • Reviewed the pi-ai library source (amazon-bedrock.js:89) to confirm requestMetadata is passed through to ConverseStreamCommand input
  • Confirmed agentId and agentName are correctly resolved from cfg.agents.list in the applyExtraParamsToAgent call path
• Edge cases checked:
  • agentId is undefined → no metadata injected (guarded by if check)
  • agentName is undefined → only agentId is injected (spread with conditional)
  • Non-Bedrock provider → metadata block is skipped entirely (guarded by provider check)
  • No extra params configured → createStreamFnWithExtraParams returns undefined early (existing guard)
• What you did not verify:
  • End-to-end verification against a live Bedrock endpoint (no AWS credentials available locally)
  • Full pnpm test suite completion (ran for 22 minutes, boundary tests passed; full suite requires CI)

Review Conversations

• I replied to or resolved every bot review conversation I addressed in this PR.
• I left unresolved only the conversations that still need reviewer or maintainer judgment.

Compatibility / Migration

• Backward compatible? Yes
• Config/env changes? No
• Migration needed? No
• If yes, exact upgrade steps: N/A

Risks and Mitigations

• Risk: requestMetadata keys with the openclaw: prefix could conflict with user-defined metadata if a future config option allows custom requestMetadata.
  • Mitigation: The openclaw: prefix is namespaced to avoid collisions. If a config-driven requestMetadata option is added later (as suggested in #60602), it should merge with — not override — the auto-injected agent metadata.
