03/20/2026, 4:15 PMupdateTools() the agent believes it has tools but they fail to execute. I want to help narrow this down and find a practical workaround that keeps you in TypeScript.
Could you provide the following so I can investigate and suggest a targeted fix or workaround?
1. Version info
◦ The agents-js (or relevant TypeScript SDK) package version you’re using.
◦ LiveKit server version (if known).
1. A minimal repro / code snippet
◦ The code where you create the agent and call updateTools().
◦ How you define the original tools and the updated tools you pass into updateTools().
1. Runtime behavior and logs
◦ Any console errors, stack traces, or agent telemetry when the tools “fail to execute.”
◦ What the agent reports as its tool list/state after updateTools() (if you can log that).
1. Reproduction steps and frequency
◦ Steps to reliably reproduce the issue.
◦ Does it happen every time or intermittently? Only after certain sequences (e.g., after a restart, after certain tool types)?
While you gather that, a couple of quick troubleshooting ideas you can try now (no Python required):
• Verify tool identity and handlers: Ensure the tool identifiers and handler registrations match exactly before and after updateTools() — mismatched IDs can make the agent think tools exist while handlers are unbound.
• Re-register handlers explicitly after update: If updateTools() updates metadata but does not rebind runtime callbacks, try calling the handler registration code immediately after updateTools() to reattach execution callbacks.
• Check for async timing issues: If updateTools() returns before internal setup completes, add a small delay or await any promise returned by the SDK, then validate tool readiness before invoking them.
Tell me which of the four info items you can share and whether you’ve already tried the quick checks above. With the snippet and logs I can look for likely causes and propose a specific code-level workaround.

03/20/2026, 4:17 PMupdateTools() problem (where the agent thinks it has tools but they won’t execute), and you don’t want Python workarounds. I’ll focus on helping diagnose and find a TypeScript-level resolution.
A few quick clarifying questions so I can investigate efficiently:
1. Which version of agents-js (or the TypeScript SDK package) were you using when you last saw this? If you don’t remember the exact version, a rough range (e.g., “a few months old” or “vX.Y.Z”) is still useful.
2. Do you recall whether updateTools() returned successfully (no thrown error), or did it fail silently? Any console logs or traces you saw at the time will help.
3. Can you share (or reproduce) a minimal snippet showing:
◦ How you define/register tools initially,
◦ The updateTools() call you made,
◦ Any handler registration code for tool execution.
If you can’t reproduce now, even pseudocode describing the flow is helpful.
1. Does the agent report tool metadata after updateTools() (e.g., a list of tool IDs), or does it only appear to “have” tools when you try to run them?
While you gather that, here are targeted diagnostics and quick TypeScript-centric checks that often reveal what’s going wrong:
• Verify tool IDs and handler bindings match exactly
◦ Ensure the tool ID strings you pass when registering execution handlers are byte-for-byte identical to the IDs in the tool objects passed to updateTools().
• Confirm whether updateTools() is synchronous or asynchronous in your SDK version
◦ If it’s async, await it. If it returns before internal setup completes, invoking tools immediately afterward can fail. Try:
i. Awaiting the call (if it returns a promise).
ii. Adding a short delay (100–200ms) before invoking tools as a diagnostic to see if timing is the culprit.
• Re-register execution handlers after updateTools()
◦ If updateTools() updates metadata but doesn’t rebind runtime callbacks in that release, explicitly re-call your handler registration logic immediately after updateTools().
• Inspect agent state after update
◦ Log the agent’s tool list/state immediately after updateTools() to confirm whether the SDK reports handlers are attached or only metadata exists.
If you can share the SDK version and a brief snippet or logs, I’ll inspect the likely failure modes and suggest a concrete code-level patch or small workaround you can run in TypeScript (for example, a wrapper that rebinds handlers automatically after updateTools()).
Which of the items above can you share now? I’ll prioritize a TypeScript solution and avoid suggesting Python.

03/20/2026, 4:18 PMupdateTools() is being invoked inside the Tasks flow (not directly by your code). I’m sorry this is blocking you — that’s understandably frustrating.
Here’s what I can confirm and how I can help next:
What’s true right now
• The issue you described (after updateTools() the agent appears to have tools but they fail to execute) still exists in v1.2.0. There isn’t a published fix in that release for this specific behavior.
What I recommend we do next (TypeScript-first)
1. Quick targeted diagnostics you can run in your environment (no Python required):
◦ Immediately after the Tasks flow triggers the updateTools() call, capture and paste:
▪︎ The agent’s reported tool list/metadata (log whatever API exposes the current tools).
▪︎ Any errors or warnings in the console when attempting to invoke a tool.
◦ Add an instrumentation point where the Tasks code finishes updating tools (if you can hook into it) and then:
▪︎ Re-register the execution handlers for each tool ID you expect, then retry invocation.
▪︎ If you cannot re-register, log whether the handler registry still contains the expected callbacks.
1. Short TypeScript workaround you can try now
◦ Wrap tool invocation so it checks handler binding; if missing, attempt to rebind handlers from your local definitions before calling the tool. This keeps you in TypeScript and avoids relying on changing SDK internals.
1. If you can share a minimal snippet or logs
◦ Even if you don’t control the updateTools() call, the surrounding Task/agent lifecycle snippet and the agent’s tool-list output right after the update will let me propose a concrete patch or wrapper you can apply.
What I can do for you
• Review the logs/snippet you provide and propose a concise TypeScript patch (for example, an automatic rebind-after-update wrapper or a defensive invocation layer) that you can drop into your codebase.
• Watch the agents-js repo for the fix and summarize any commits or release notes that address this bug once they appear.
One small clarifying question
• Can you capture the agent’s reported tool metadata right after the Tasks flow does its update (a console.log of the agent.tools or equivalent)? That will let me determine whether metadata is present while handlers are missing — which aligns with what you described — and shape an exact rebind workaround.
If you want, paste the post-update tool listing and any console errors you see and I’ll draft a minimal TypeScript wrapper you can try immediately.

If you want to post your findings elsewhere for broader visibility, common places people use are the agents-js GitHub issues page or community discussion channels — but if you’d rather keep it here, that works fine. Which would you prefer: you post any logs here and I’ll analyze them, or I’ll keep an eye on the repo and notify you of relevant fixes/releases?

03/20/2026, 4:24 PMupdateTools() in the Tasks flow) is present in agents-js v1.0.48 and still present in v1.2.0. There’s no published fix in v1.2.0 yet.
• Where to post: Filing an issue on the agents-js GitHub repository is the right move for visibility to the maintainers and contributors.
• What I can do for you here: monitor the repo for fixes, analyze any logs/snippets you paste here, and draft a focused TypeScript-side mitigation you can apply without editing LiveKit internals.
If you want to open a GitHub issue (recommended)
• Include: SDK version(s) (you already have v1.0.48 and v1.2.0), a brief description of the observed behavior, and any repro steps you can recall (even “Tasks flow triggers updateTools() and afterwards tools report present but fail to execute” is useful). Mark it as potentially related to updateTools() / Tasks / tool handler binding.
• If you prefer, paste the text you want to post and I’ll help you format it succinctly for the issue.
If you want to keep working here first
• I’ll do two things for you:
a. Keep watching the agents-js repo and call out any commits or releases that mention Tasks, updateTools(), or tool binding fixes.
b. Help you draft either:
• A small defensive TypeScript wrapper you can add to your app (no SDK changes) that detects missing handlers and attempts a safe rebind or retries invocation, or
• A concise GitHub issue body that provides the exact context devs need to reproduce and fix this in TypeScript.
• If you find any logs or a post-update tool listing, paste them here and I’ll analyze immediately and draft a minimal code workaround you can try.
One quick question to help me prioritize:
• Do you want me to prepare a GitHub issue body for you to paste (I’ll include the versions and the failure description), or would you prefer I hold off and only act once you post findings here?
I’ll follow whichever you choose — and I’ll focus strictly on TypeScript solutions and keeping the devs aware through the repo.
