@kaegie I had to implement Jira integration where I had to fetch custom fields based on ID type provided by user which require lot of data transformation for Agents to work with, since then this is first rule of thumb to always minimize token usage :)

[Vikash Bhardwaj @vikash21]

@kaegie Sometime people learn it by experience when they use their own subscription to pay for tokens, I recall building my first Agentic coding product in 2023...

Improving Deep Agents with harness engineering 👀

Our coding agent went from Top 30 to Top 5 on Terminal Bench 2.0. We only changed the harness.

The goal of a harness is to mold the inherently spiky intelligence of a model for tasks we care about.

Harness Engineering is about systems. You’re building tooling around the model to optimize goals like task performance, token efficiency, latency, etc. Design decisions include the system prompt, tool choice, and execution flow.

But how should you change the harness to improve your agent? (teaser: self-verification & tracing with LangSmith help a lot)

Gemini 3 has impressive benchmarks for building agents (Vending-Bench 2, Terminal Bench, and Sierra).

So we tested its performance as a research agent using Deep Agents.

We found Gemini 3 is very effective at using research tools like file manipulation, planning, and subagent delegation. All essential for building deep agents.

Microsoft did it again!

Building with AI agents almost never works on the first try.

You spend days tweaking prompts, adding examples, hoping it gets better. Nothing systematic, just guesswork.

This is exactly what Microsoft's Agent Lightning solves.

It's an open-source framework that trains ANY AI agent with reinforcement learning. Works with LangChain, AutoGen, CrewAI, OpenAI SDK, or plain Python.

Here's how it works:

> Your agent runs normally with whatever framework you're using. Just add a lightweight agl.emit() helper or let the tracer auto-collect everything.

> Agent Lightning captures every prompt, tool call, and reward. Stores them as structured events.

> You pick an algorithm (RL, prompt optimization, fine-tuning). It reads the events, learns patterns, and generates improved prompts or policy weights.

> The Trainer pushes updates back to your agent. Your agent gets better without you rewriting anything.

The best part: you can also optimize individual agents in a multi-agent system.

I have shared the link to the GitHub repo in the replies!

Let me know if I should cover this in a video demo!

@ravipal1214 Even though Google have platforms to take benefit of this race but I feel there is going to be tough race here because others are already have upper hand at least in LLMs for speed n accuracy, will explore more on enterprise side in coming days

Subject: Complaint Regarding Encroachment and Un-authorised Use of Public Spaces in Market Corridors of Main Market, Sector 21 C, Faridabad, Haryana

To
The Municipal Corporation of Faridabad, Haryana, India
Twitter Handle: @MCF_Faridabad

Respected Sir/Madam,

I am writing to bring to your urgent attention the issue of encroachment of public spaces in market corridors by shop owners, particularly restaurants, in Main Huda Market, Sector 21C Market of Faridabad, Haryana. This encroachment not only obstructs the free movement of customers and market goers but also poses significant risks to public safety.

Details of the Complaint
1. Encroachment of Public Space: Most shop owners in the market have illegally occupied public corridors meant for walking by blocking the right of passage.
2. Illegally Barricading Corridors: Shopkeepers have placed permanent grills and barricades, making it impossible for customers to walk safely in designated spaces.
3. Blocking Parking Areas: Unauthorized barricades using personal grills are blocking parking spaces, forcing customers to park at a distance and causing congestion in the area.
4. Safety Hazards: Some restaurants have placed gas cylinders and heavy electrical equipment in the walking corridors, posing significant safety risks for market visitors.
5. Forcing Longer Routes: Due to the illegal barricades and grills, market visitors are forced to take inconvenient and unsafe longer routes to reach their destination shops.
6. Unauthorized Use of Public Space for Commercial Gains: Many shopkeepers are misusing public space for personal and commercial activities without permission.
Expectations from MCF

I request the Municipal Corporation of Faridabad to take the following immediate actions to address this issue:
1. Remove Illegal Barricading: Dismantle all unauthorized barricades and grills set up by restaurants and shopkeepers in public areas.
2. Clear Parking Areas: Remove any encroachments or unauthorized structures blocking parking spaces meant for public use.
3. Enforce Public Safety Regulations: Ensure that hazardous items such as gas cylinders and heavy electrical equipment are removed from walking corridors.
4. Enable Free Movement: Restore free and safe passage for customers and market goers in all designated areas.
5. Policy Implementation: Formulate and enforce clear policies regarding the use of rental and public spaces to prevent future encroachments.
6. Dismantle Illegal Shops: Take strict action against any unauthorized shops operating in public spaces.

Supporting Evidence
We urge your team to visit the market and inspect the situation. The illegal encroachments and safety hazards are visible daily and can be documented for further action. Please find attached pictures of one such restaurant taken on 29th November 2024

We believe the swift action of the Municipal Corporation will ensure a safer and more organized market environment for everyone. Thank you for your attention to this matter. We look forward to your prompt response and necessary action.

Sincerely, 
Citizen, Sector 21C, Faridabad
