Closes Stellar-Tools#38 ## What was added ### utils/metrics.ts (new file) TransactionMetrics class that tracks swap, bridge, and LP operations in-memory with a simple API: - track(type) — starts timing, returns a finisher function to call on completion - summary() — aggregated metrics: successRate, totalVolume, avgSlippage, avgDurationMs, byType - history() — raw list of all TransactionRecord entries - byType(type) — filter records by operation type - recent(n) — last N transactions - clear() — reset all records ### agent.ts - Added TransactionMetrics import and public readonly metrics property - Wrapped swap() with metrics tracking (success/failure + inputAmount) - Wrapped bridge() with metrics tracking (success/failure + inputAmount) ### tests/unit/utils/metrics.test.ts (new file) 12 tests covering all public methods: track: success, failure, duration timing, unique IDs summary: zero state, success rate, total volume, avgSlippage (success-only), byType counts byType: filtering recent: last N records clear: full reset ## Results Tests: 12 passed (0 failed)

- Make track() finisher idempotent (duplicate calls return existing record) - Fix totalVolume to use safe parseFloat with NaN guard via Number.isFinite - Add metrics tracking to lp.deposit() and lp.withdraw() - Fix swap inputAmount to also record outputAmount (params.out)

Hey @daiwikmh! The CI checks are failing at the "Setup Node.js" step, which appears to be a runner infrastructure issue rather than a code problem — I can see the same Could you approve the workflow run so CI can execute? That would confirm the tests pass on your end too. Also, all 4 issues flagged by Cubic AI in the first review have been addressed in the latest commit:
Thanks! |

Hi @daiwikmh! Thanks for checking. The CI failure is at the "Setup Node.js" step — not in the actual test code. This is a GitHub Actions infrastructure issue where workflow runs from external contributor forks require manual approval before they can execute. The tests pass fine locally: Could you click "Approve and run" on the workflow to allow CI to execute? Once approved the tests should pass and this should be ready to merge. All 4 issues from the Cubic AI review have also been addressed in the second commit. The Cubic AI re-review shows ✅ Successful. |

Summary
Closes #38
Adds a
TransactionMetricsclass and wires it intoAgentClientasagent.metrics.*. Previously swap, bridge, and LP operations executed blindly with no tracking, debugging visibility, or performance insights.What was added
