fix(agents): merge upstream agent runtime refactor with Sprint 3.5-3.7 customizations by Copilot · Pull Request #88 · Piboonsak/openclaw_github

Copilot · 2026-04-06T02:55:01Z

Summary

Problem: Upstream heavily refactored tool-loop-detection and pi-tools.before-tool-call while our Sprint 3.5–3.7 PRs (feat(agents): rapid-succession storm detector + callTrace to prevent nested-agent tool storms #56 storm detector, feat(agent): enable reasoning mode as default #78 reasoning mode) added tests/features to the same files. Our rapid_succession detector (fires at ≥15 consecutive same-tool calls, any args) broke pre-existing tests that make 15–30+ consecutive calls to exercise other detectors. Additionally, normalizeToolName("bash") → "exec" via TOOL_NAME_ALIASES caused a toolName assertion mismatch in storm tests.
Why it matters: 8 tool-loop-detection tests and 7 before-tool-call tests were failing in CI; storm detection and reasoning-mode features were unverifiable.
What changed: Fixed both test files to coexist with the rapid_succession detector; applied upstream normalizeProviderId refactor to history.ts; added provider-id.ts from upstream.
What did NOT change: tool-loop-detection.ts (our new file, untouched per spec); model-selection.ts (PR feat(agent): enable reasoning mode as default #78 reasoning default already applied); pi-tools.before-tool-call.ts (PR feat(agents): rapid-succession storm detector + callTrace to prevent nested-agent tool storms #56 callTrace already applied); compact.ts/errors.ts (upstream versions require 10+ new dependency files — deferred).

User-visible / Behavior Changes

None. All changes are internal test fixes and upstream normalization logic for provider ID lookup in history config.

Repro + Verification

Environment

OS: Linux (CI)
Runtime/container: Node 22 / Vitest 4
Model/provider: N/A
Integration/channel (if any): N/A
Relevant config (redacted): N/A

Steps

pnpm test -- src/agents/tool-loop-detection.test.ts src/agents/pi-tools.before-tool-call.test.ts

Expected

All 44 tool-loop-detection tests pass
All 13 before-tool-call tests pass

Actual

Before: 8 failures in tool-loop-detection.test.ts, 7 in pi-tools.before-tool-call.test.ts
After: 208/208 tests pass across all affected files

Evidence

Failing test/log before + passing after

Before (sample failures):

FAIL tool-loop-detection > detectToolCallLoop > does not flag unique tool calls
AssertionError: expected true to be false  // rapid_succession fires at call 16

FAIL before-tool-call > rapid_succession storm detection > blocks a tool storm
AssertionError: expected 'exec' to be 'bash'  // normalizeToolName alias

Fix pattern — tool-loop-detection.test.ts:

// Config variant that disables rapid_succession so other detectors can be tested
// without interference from consecutive same-tool-name triggering.
const noRapidSuccessionConfig: ToolLoopDetectionConfig = {
  enabled: true,
  detectors: { rapidSuccession: false },
};

// Before: used enabledLoopDetectionConfig (rapid_succession fires at call 16)
// After: use noRapidSuccessionConfig (only the target detector is exercised)
it("does not flag unique tool calls", () => {
  for (let i = 0; i < 15; i += 1) {
    recordToolCall(state, "read", { path: `/file${i}.txt` }, `call-${i}`);
  }
  const result = detectToolCallLoop(state, "read", { path: "/new-file.txt" }, noRapidSuccessionConfig);
  expect(result.stuck).toBe(false);
});

Fix pattern — before-tool-call.test.ts:

// "bash" normalizes to "exec" via TOOL_NAME_ALIASES in runBeforeToolCallHook
expect(stormEvent?.toolName).toBe("exec");
expect(stormEvent?.callTrace?.at(-1)).toBe("exec");

Human Verification (required)

Verified scenarios: rapid_succession detector still fires correctly in its own test suite (44 passes); storm integration test correctly detects bash-as-exec storm; known_poll, generic_repeat, global_circuit_breaker detectors all fire correctly when rapid_succession is disabled in their tests; history.ts provider lookup normalization tested via 138 pi-embedded-runner tests.
Edge cases checked: can disable specific detectors test now also disables rapidSuccession: false so all-off config truly returns stuck: false; callTrace in all detectors tests updated similarly.
What you did not verify: live gateway execution of storm scenarios end-to-end; compact.ts/errors.ts upstream replacements (deferred due to missing dependency chain).

Compatibility / Migration

Backward compatible? Yes
Config/env changes? No
Migration needed? No

Failure Recovery (if this breaks)

How to disable/revert this change quickly: git revert HEAD — test-only + provider-id utility changes, no runtime behavior changed.
Files/config to restore: src/agents/tool-loop-detection.test.ts, src/agents/pi-tools.before-tool-call.test.ts, src/agents/pi-embedded-runner/history.ts, src/agents/provider-id.ts
Known bad symptoms reviewers should watch for: if RAPID_SUCCESSION_THRESHOLD is lowered below WARNING_THRESHOLD (10), the noRapidSuccessionConfig guard in non-storm tests becomes unnecessary but harmless.

Risks and Mitigations

Risk: Tests that disable rapidSuccession might mask a real storm if the tool name changes.
- Mitigation: Only non-storm tests disable it; the dedicated rapid_succession detector suite (8 tests) always runs with enabled: true and exercises the full detector path including bash→exec normalization.
