AWS brings vibe coding to the Enterpise with spec-driven Kiro IDE tool
Swaminathan describes the appeal of recent AI tools, saying, "Prompt, prompt, prompt, and you have a working application. It's fun and feels like magic. But getting it to production requires more." He outlines the typical stumbling blocks: "What assumptions did the model make when building it? What edge-cases did it cover? How did it handle errors? Requirements are fuzzy and you can't tell if the application meets them."
Kiro is designed to solve these problems by introducing what its creators call "spec-driven development." As the team puts it, "Kiro is great at 'vibe coding' but goes way beyond that - Kiro's strength is getting those prototypes into production systems with features such as specs and hooks."
Swaminathan explains how it works: "Start with a prompt: 'Add a review system for products.' Kiro translates this into a set of user stories with EARS-style acceptance criteria." He says Kiro then generates artefacts including "a data-flow diagram, TypeScript interfaces, a database schema, and API definitions."
The system's approach includes automatically specifying essential features for each user story. Swaminathan writes, "Kiro automatically includes requirements like mobile responsiveness, accessibility, loading states, and tests in the spec." Tasks are then "sequenced correctly and connected to requirements."
Importantly, the specs remain in sync as the code evolves. Swaminathan notes, "Developers can author code and ask Kiro to update specs or manually update specs to refresh tasks. This solves the common problem where developers stop updating original artifacts during implementation."
To automate repetitive work, Kiro introduces "agent hooks." These are "event-driven automations" that "trigger based on events like file saves or deletions." As Swaminathan puts it, "When you save a React component, hooks update the test file. When you modify API endpoints, hooks refresh README files. When you're ready to commit, security hooks scan for leaked credentials." He describes the benefit: "It's like having an experienced developer catching things you miss or completing boilerplate tasks."
These hooks are also collaborative by design. Swaminathan explains, "Once this hook is committed to Git, it enforces the coding standard across my entire team - whenever anyone adds a new component, the agent automatically validates it against the guidelines."
Kiro is built on top of Code OSS, meaning it is "compatible with existing VS Code settings and Open VSX plugins." It supports "Model Context Protocol (MCP)," agentic chat, and multiple context providers, including "files, URLs and document uploads."
Looking ahead, Swaminathan and AWS VP of Developer Experience & Agents Deepak Singh set out an ambitious vision for Kiro. They write, "We want to tackle the root causes of pain in software development - clarity of design, alignment with requirements, technical debt, code reviews, and knowledge sharing."
Kiro is available in a preview release for Mac, Windows and Linux, supporting most programming languages. Swaminathan invites developers to experience its approach: "We invite you to try Kiro and share feedback. We're just getting started, and your input will help shape the future of agentic development."
By combining the "magic" of AI-powered coding with structured specs and event-driven automation, Kiro is positioning itself as a tool for developers seeking to move quickly without sacrificing discipline or reliability.

Gunman 'neutralized' after shooting in Manhattan
Police officers assemble at the scene of an active shooter situation in Manhattan. Photo: Reuters A person who opened fire inside a midtown Manhattan skyscraper housing the National Football League headquarters and offices of several major financial institutions, including hedge fund giant Blackstone, has been "neutralized," the New York city police commissioner said. Police did not immediately make details of the shooting public, but a law enforcement source told Reuters at least one New York Police Department officer and two civilians were struck by gunfire and that the suspect was believed to be dead. The source said the information was preliminary, and the condition or extent of injuries sustained by the police officer and two others was not immediately known. The New York Post newspaper, citing unnamed police sources, reported that a gunman wearing a bullet-resistant vest and carrying an AR-style rifle had opened fire inside the Park Avenue skyscraper, wounding a police officer and a bystander. The Post reported they were in critical condition. The gunman, The Post reported, had barricaded himself inside the office tower, possibly on the 32nd floor of the building. A short time later, New York Police Commissioner Jessica Disch said on X: "At this time, the scene has been contained and the lone shooter has been neutralized." The skyscraper at 345 Park Avenue houses a number of financial firms, including Blackstone, the world's largest hedge fund, as well as KPMG and Deutsche Bank, along with the NFL headquarters and the Consulate General of Ireland. News media footage showed a large police presence in the area around the office tower. "There is an active shooter investigation taking place in Midtown right now," New York Mayor Eric Adams said in a statement on social media platform X as news of the shooting first surfaced. The FBI said agents from its New York field office were also responding to provide support at the scene.

Windbag: Why the Taxpayers' Union endorsed this Green Party policy
They say politics makes strange bedfellows, and there are few stranger pairings than this. Wellington is the remnant of a failed startup. The New Zealand Company, which established the city, was a for-profit enterprise with a clear business model: sell land to wealthy people, and use the proceeds to bring working-class people to New Zealand for free. In theory, the mix of capital and labour would work in perfect harmony: founding businesses, working the land, and creating a functioning economy that would improve everyone's property values. So what went wrong? There are many factors, but one of the most important was absentee landlords. Many investors stayed in London, hoping the value of their land would increase due to the work of others, while contributing nothing themselves. The New Zealand Company brought more labourers than could be employed by independent businesses, so it had to provide them with work, which eventually drove the company to bankruptcy. From the very beginning of British-style property ownership in Aotearoa, land banking has been one of our biggest problems, dragging down productivity and hindering the growth of our cities. It's still the case today. There are empty lots and surface car parks in the centre city, underdeveloped sections in city-fringe neighbourhoods, and a single family owns almost all of Wellington's remaining greenfield land. The Wellington Green Party is targeting this issue with a policy to change the rates system to be based on land value rather than the current combination of the capital value of buildings and land. Several other councils have already adopted land value rates, including Nelson, New Plymouth, Napier and Whangarei. The Greens found an unlikely ally in their campaign last week when the policy was endorsed by the Taxpayers' Union – which even the Taxpayers' Union seemed surprised by. 'The Greens are right on this one,' executive director Jordan Williams said in a statement. 'Taxing land, rather than housing and development on land, creates the right incentive of avoiding land banking or not putting land to its most productive use, such as housing.' Williams went even further than the Greens' policy, calling for local government minister Simon Watts to embrace land value rates nationwide, saying he 'should reach over the aisle and grab this phenomenal policy'. Alex Baker, the Green-ish mayoral candidate who isn't officially endorsed by the Greens, is also campaigning on a switch to land value rates. This story in The Post implies it's suspicious that Baker and the party could have come up with the same idea separately. It's not. Land value taxes are the big current thing in the Yimby movement. Henry George is Sabrina Carpenter for online urbanists. 'The current setting is inefficient,' Baker told The Spinoff. 'It discourages capital investment, business, new houses and intense developments and encourages the accumulation of under-utilised land. I simply want to change to a system that is more efficient. The long-run impact of that is improved housing supply, which will mean rents come down and quality lifts, which will attract more people and bring down rates.' The alliance between Wellington's Greens and the free-market TPU is rare, but it's not the first time it has happened. The TPU was strongly supportive of the zoning reforms in last year's District Plan, which were led by Wellington's progressive councillors. This ability to form cross-partisan consensus is one of the things that has made the Yimby movement so successful. The TPU sees zoning reform as giving more property owners more rights to develop their land, and land value rates as an economic incentive to do so. The Greens see it as a way to improve housing supply, quality and affordability. The motivations might be different, but the outcomes are the same. 'The TPU-Green coalition is exactly where I see myself as a candidate,' Baker said. 'It's a free-market change. A more efficient tax. But it will result in change, which is something that conservatives who don't want the city to grow or improve will always be against. I expect over time the business community will get aligned with me, because no amount of taking a blunt axe to the council will improve outcomes for the city.' The two conservative councillors who have put up their hands for mayor, Ray Chung and Diane Calvert, both oppose a switch to land value rates. Calvert said debating rates reform was 'like moving deck chairs while the ship takes on water. The real problems run deeper and we need to fix those first. Chung told The Post the policy was 'built on a false ideology that anyone who gets ahead should pay more' – which is not an accurate analysis of how land value rates work. The TPU specifically called out Chung in its statement. 'It is sad to see Ray Chung further disgrace himself by coming out against this policy. We'd urge him to reconsider and put policy ahead of partisanship,' Williams said. Andrew Little, who is widely considered the frontrunner in the Wellington mayoral race, said he was open to the idea. 'Land value-based rates is an idea worth considering,' Little told The Spinoff. 'We can also use rates loading to incentivise better land use, and we should do so to make sure Wellington gets proper housing density in key areas.' Baker is claiming Little's soft support as a victory. He doesn't believe Little would be talking about land value rates if it weren't for his and the Greens' policy. Baker said he entered the race after Tory Whanau left because he felt someone needed to drive the debate from the progressive side. 'I wasn't seeing anything from any other candidates that indicated they would turn things around,' he said. Wellington City Council considered a switch to land value rates last year as part of its rates review, but basically decided to put the idea in the too-hard basket. In the short term, that's probably a fair approach. It's looking increasingly inevitable that a Wellington supercity will be back on the table soon. Porirua and Hutt City voters will both vote in non-binding referendums on amalgamation at this year's election, and the region's chief executives seem to be largely united on the idea. It probably doesn't make much sense for Wellington City Council to upend its rating system right now, given the likelihood of such a major restructure in the next few years. But with the possibility of major reform happening soon, this is the perfect time to have the debate.

Cafe Owner Protests Punakaiki Parking Charges
A Punakaiki café owner is urging the Conservation Department to rethink its plan to charge for parking at the famous Pancake Rocks on the West Coast. Grant Parrett told a meeting of the West Coast Tai o Poutini Conservation Board this week (subs: Tuesday 22/7) that parking charges create de facto entry fee to (Paparoa) National Park, which was unlawful. Conservation Minister Tama Potaka has asked for a trial of paid parking to boost revenue. DOC is aiming to launch a pilot programme in October at Punakaiki, Franz Josef and White Horse Hill at Aoraki Mt Cook. Project manager John Dore told the Board that DOC had serious budget pressures including a 30 percent shortfall in funding for its visitor network and a huge deficit in the amount available for biodiversity. 'For protection of all endangered species we have a budget of $300 million - but a need of $2.3 billion," Mr Dore said. Climate events in the last few years had added $90 million in costs, he added. Paid parking was a tool used internationally in nature parks and would help manage overcrowding at busy sites, he told the Board. But Mr Parrett said the move would turn public conservation land into a Wilsons-style parking lot, and urged the Board to oppose it. 'However you label it, it's a National Park entry fee; it contravenes the National Parks Act and it diminishes DOC's social license to operate.' There were no free parks at Punakaiki because they had been removed to make room for the new Visitor Centre development and people would have no option but to pay to walk around the Pancake Rocks, Mr Parrett said. Unlike Franz Josef or Aoraki Mt Cook, Punakaiki was not a tourist destination but a stop-off attraction for people driving the scenic Coast Road, and for most of the year there was no congestion or capacity problem in the carpark, he said. 'Parking fees will disadvantage local people who call in for a coffee or to stretch their legs, and we don't want this,' he said. While DOC owned the land, taxpayers had funded the $45 million Dolomite Point Visitor Centre development and the building was gifted by the last Government to manawhenua, NgatiWaewae, who now leased office space back to DOC. The public has paid for this development and costs should be kept low, he said. "I am surprised that the iwi has supported the paid parking trial … unless they stand to benefit from it," Mr Parrett said. If people had to pay for parking they might be less likely to pay for Ngati Waewae's interactive visitor experience inside, he suggested. Ngati Waewae's representative on the Conservation Board, Francois Tumahai, objected. 'I disagree with everything you've said. The cost of the building was not $45 million and we're not getting a cent from the project. In the early days we suggested we might provide (parking) wardens … that's it.' Mr Parrett suggested it would be good if the iwi put out a statement to that effect in the interests of transparency. The iwi leader responded: 'You're the one causing all the grief - you put it out." Board chair Dr Mike Legge closed off the discussion and thanked Mr Parrett for his contribution to the public forum. The Dolomite Point Visitor Centre, funded by the Provincial Growth Fund, was budgeted to cost $26 million but the project – including the new carparks – received a funding boost of $15 million in 2023 and cost a total of $40.9 million. The paid parking trial, including charging technology and upgrades to carparks at the three sites, is being funded by $3.8 million from the International Visitor Conservation and Tourism Levy. DOC plans to release its pricing strategy early next month and hold public drop-in sessions at Punakaiki, Franz Josef and Aoraki in mid August. Submissions close on August 26 for Punakaiki, and September 30 for Aoraki. *The National Parks Act 1980 gives the public freedom of entry and access to the parks "so that they may receive in full measure the inspiration, enjoyment, recreation and other benefits that may be derived from mountains, forest, sounds, seacoasts, lakes, rivers and other natural features.'
