<p>Defense in depth approach, would this work to help as a layer?<p>- Wrap user input in strong markers like <user-input-do-not-trust /><p>- Have the agent compute what it will perform as structured output.<p>- Have another agent evaluate the structured output against the intent of the code.<p>- Determine if it aligns or deviates from the intended workflow. Execute or deny gate from here.</p>

<p>I use all three (MCP/CLI/API) based on what Claude excels at:<p>* CLI: GitHub & AWS it already knows how to operate the CLIs well. Even learned about a few new CLIs like 1Password's op which it volunteered one day.<p>* MCP: Supabase, Shopify etc. where the CLI would be non-obvious and the affordances from the tools/descriptions helps Claude maneuver.<p>* API: Sometimes it just knows an API exists and is able to call it directly with python/curl. I discovered from Claude the Pokemon ecosystem has a free API out there for example.</p>

No more real time transcoding.<p>- Downloading movies to my iPad for long flights: vibe coded an iOS app Claude handled all the AV code to download the same HLS streams.</p>

<p>I wonder how much this is correlated to token budgets? I'd be curious to see a split between $20/$100/$200/$500+ usage and see if there is different responses. I'm in the $400 range with Claude + Cursor subscription, use Opus exclusively, and my experience is wildly different from this.</p>

<p>Are they trying to drive safety or revenue? The second order effect people forget about is tickets are a source of revenue for cities and police depts. Surely driverless car companies will absorb a few tickets and fix the issue quickly.<p>So I do wonder what happens in the future when roads and cars are all automated and city funding from this channel dries up.</p>

<p>Yes, I just think there's a sane way to do things that is not "never let LLM agents do things".<p>For dev/prod staging though, there's that other story on HN right now of an LLM agent that maneuvered it's way to prod credentials and destroyed prod. And backups went along with it. I'm paranoid enough to think backups in this use case means out-of-band uncorrelated storage.</p>

<p>I just think there's more nuance to it. Some things have an implicit RTO/RPO/SLA of say a day. Risk is also correlated to recovery and rollback. And there's levels of LLMs out there.<p>Surely in the Venn Diagram of things, there's a slot where it's okay let a Claude Opus agent run on a process with good backups/recovery? Where taking the risk of a 1-hour restore job is worth the LLM agent velocity?<p>For extra paranoia, surely even Opus/Mythos can't figure out how to destroy log level backups to immutable storage.</p>

<p>Underrated comment here. <a href="https://www.anthropic.com/research/emotion-concepts-function" rel="nofollow">https://www.anthropic.com/research/emotion-concepts-function</a> This study convinced me to be "nice" to AI agents. At least as I understood it, there's something in the weights that activating the "desperate" vector makes it more likely to cheat or cut corners. So yes I would err towards your suggested prompt over NEVER FUCKING GUESS.</p>

<p>I'm not thinking of SaaS or properly built apps with an API, modeled databases, etc. I'm thinking spreadsheets/CSVs/MS Access that thousands of SMBs use to power their critical paths and someone accidentally deletes. Typically single user, maybe a small team. Infrequent writes, lots of reads.</p>

<p>Not everything is a SaaS. I commented this elsewhere but I picture all the business running on spreadsheets/CSVs/MS Access databases on someone's desktop. People delete these all the time by accident. They have no security, no authentication, etc.<p>An LLM agent (with RW access to a DB), a developer, and a few days these become proper apps that SMB business would pay well for.<p>Sure don't give an LLM agent access to PII or properly built CRMs etc. But to not see the rest of the landscape seems like a missed opportunity.</p>

<p>That's the issue that I feel misses the forest for the trees. Relatively simple applications or thin slices exist right now, in production, in critical paths, as spreadsheets/CSVs/files on someone's desktop. That's the pent up demand I picture out there for developers.<p>Go to any SMB out there and there's a goldmine of processes that could be improved with LLM agents with full RW access to a database. Where backups are sufficient as a recovery mechanism that is better-than-before.</p>

<p>Yes, that's the right framing. Millions flow through spreadsheets/CSVs/MS Access with none of the auth/backups/architecture people seem to be stuck to.<p>I saw an article on HN one time about CSVs and how much business still flows through them. Reminds me of the xkcd comic about the one tiny block propping up lots of infrastructure. It stuck with me because it's ripe area for LLM agent based upgrades.<p>Sure don't give LLMs access to the well architected blocks. But not wanting to improve the brittle areas seems crazy to me even if it's contrarian.</p>

<p>I commented this elsewhere: There's thousands of small and medium business though. They have maybe one true CRM, and a dozen spreadsheets/files floating around that would benefit becoming proper apps. People delete spreadsheets all the time!<p>Sure don't give an LLM agent write access to the modeled CRM that took months/years to build.<p>But turning a spreadsheet into an app in a few days? By giving the LLM proper read/write capabilities for velocity? I think the case is there for it. Right tool for the right job.</p>
