Google Antigravity Agents Gain Interactive UI Skills via SKILL.md Instructions

·3 views

A developer tutorial published on DEV Community explains how to embed native chat UI components into Google Antigravity agent skills using a SKILL.md instruction file. By invoking the ask_question tool, agents can pause execution and display interactive modals featuring radio buttons, checkboxes, and text fields instead of guessing user inputs. The approach pairs UI interactions with persistent state hydration, storing user preferences in a JSON file so settings carry over across sessions and subagents. This method builds on Antigravity's built-in /grill-me slash command, extending it with custom, reusable skill workflows. The guide is the first in a five-part engineering series covering agent tools such as ask_question, generate_image, define_subagent, send_message, and manage_subagents.

Six Prompt Techniques to Stop AI Chatbots From Cutting Off Long Outputs

AI language models have built-in token limits and output restrictions that cause them to stop generating text mid-response, frustrating users working on lengthy code, essays, or emails. A guide published on DEV Community outlines six practical prompting strategies to work around these limitations. Key advice includes specifying exact output length and structure upfront, breaking large tasks into clearly numbered parts, and requesting all sections explicitly in a single prompt. Using words like 'comprehensive,' 'exhaustive,' or 'complete' can signal the model to allocate more of its output budget to the response. The guide emphasizes that these stopping points are predictable and can be managed by giving the AI precise, detailed instructions before generation begins.

PAGI::Server 0.002007 unifies HTTP/1.1 and HTTP/2 under a single contract

PAGI::Server 0.002007 is the most significant release of the Perl async web server framework to date, centered on normalizing behavior across HTTP/1.1 and HTTP/2 transports. The release makes event validation mandatory and always-on, deprecating the previous opt-in validate_events flag, so malformed or out-of-sequence events now consistently fail rather than being silently ignored. Error reporting has been standardized, with socket errors now distinguished by type — such as read_error, write_error, or idle_timeout — instead of all appearing as generic client disconnections. WebSocket and response lifecycle handling has been unified across both transports, ensuring incomplete responses trigger proper abnormal closure and disconnect events fire exactly once. The release ships with 920 tests across 133 files, and benchmarking showed no performance regression from unconditional validation, with a dedicated performance-focused update already in progress.

UwView Tool Lets Engineers Trace Log Errors Back to Root Cause Without Unpacking Files

When investigating software incidents, the visible ERROR line is typically the result of an upstream cause such as a timeout or misconfiguration logged earlier. Traditional tools like grep require guessing context width in advance and lose the original file position, making deep investigation cumbersome. UwView, a log analysis tool, addresses this by letting users open multi-gigabyte compressed files instantly and drill down through search hits while remaining anchored to the original file. A demonstration using the 258 GB US OpenStreetMap XML file showed the tool narrowing 100,492 hits to 3 in two drill-down steps, with full surrounding context preserved. The free edition covers core investigation features, while UwView Pro v1.3.0 and above adds extended context, multiple independent search popups, and fast index-based reopening for daily use.

Why .env.example Files Go Stale and How Schema-Based Tools Fix It

The .env.example file is a common developer convention for documenting required environment variables, but it has no built-in mechanism to stay in sync with the codebase that depends on it. When a developer adds a new variable like STRIPE_WEBHOOK_SECRET, nothing in the workflow enforces an update to the template, so it silently drifts over time. New team members who clone the repo and copy the file often end up with incomplete configurations, causing runtime crashes. Approaches like manual code review checklists or custom diff scripts offer partial relief but cannot detect variables missing from both files or validate value formats. A schema-based approach, as implemented by tools like EnvShield using an env.schema.toml file, generates and validates .env.example automatically, catching drift at commit time rather than after the fact.
