They could and code execution is actually exposed to the model as a tool!

But if im running a customer support agent at scale, i'm not sure I want it to be able to write code. I do know I need it to be able to convert timezones though. (its also far more expensive / token inefficient to have it write code each time to convert timezones rather to use a predefined tool I made an know works)

Re:Why MCP Was Always a Bad Idea on Monday September 21, 2026 @01:12PM (#49790179)
> If you often need timezone conversion, sounds like a `timezones` skill exposing a few lines in a Python script. Boom. No MCP needed. No server needed

okay, but now my agent needs a coding environment / sandbox.

MCP (or tool use in general) solves this without that (extremely tenuous and expensive to do at scale in prd) requirement.

The skill is totally orthogonal here--solving a totally separate problem

Re:Why MCP Was Always a Bad Idea on Monday September 21, 2026 @12:13PM (#49789216)
Skills are adjacent to MCP. They do not cover the same surface, in anyway. I don't understand this argument at all (and I see lots of people making it, so enlighten me)

I want my agent to be able to convert reliably between timezones. A skill does not solve this. It needs a deterministic tool it can call

Sounds like its essentially a generalized zero-shot classifier that takes and option set at runtime and works on unstructured inputs.

you pass in your "prompt" and options (described in natural language) that it can respond with, in addition to your input. it gives back that option set with a probability assigned to each one

fair i guess. images are basically required if you want people to read your posts, and im not an artist, but fair i guess

calling my whole site AI slop is a bit rude but mostly just wrong. I have put in a lot of work to my posts and my projects.

and, > "I don’t think the author could explain what the second part of the article is supposed to mean"

??? its a bit. half the post is a bit. im leaning into it. _The weights were revealed inside a harness_ is literally glowing. wdym i cant explain any of it

Re:Gemini 3.6 Flash, 3.5 Flash-Lite, and 3.5 Flash Cyber on Tuesday July 21, 2026 @04:49PM (#48998099)
it does seem to be moving in that direction. There were really specific things (large, complex json outputs) that gemini-2.5 flash was basically the only model that seemed capable of reliably for a long period. gpt-5+ has covered the usecase for us now pretty well but still evals slightly below what 2.5 could do
they say the model(s) found and exploited a zero day
Re:Gemini 3.6 Flash, 3.5 Flash-Lite, and 3.5 Flash Cyber on Tuesday July 21, 2026 @12:34PM (#48994634)
its not always that simple. dropping in a new model is trivial, but highly specific workflows may rely on specific _invisible_ aspects of a model. when that model gets deprecated, the workflow needs to be rebuilt/re-tuned to work with a different model.

google's inability or unwillingness to provide stable timelines for model deprecation makes it risky to build complex workflows using their models

Show HN: TinyFn – 500 deterministic utility APIs for AI agents (via MCP)

https://tinyfn.io

Hey HN,I built TinyFn because LLMs are bad at the boring stuff — counting letters, validating emails, converting units. But they're even worse at things that are literally impossible for them: hashing, regex execution, UUID generation. An LLM will never produce a correct SHA256 hash.TinyFn is a set of 500+ simple, deterministic utility endpoints that agents can call via MCP or plain REST.The...

same--this is exactly why I built this
Re:Show HN: TinyFn – Your agent sucks at math on Wednesday February 04, 2026 @10:19AM (#46886889)
LLMs absolutely do not have access to the same tools unless they're explicitly given access to them. Running on a computer means nothing.

It sounds like you don't like LLMs! In that case, you may be more interested in our REST Api. All the same functions, but designed for edge computing, where dependency bloat is a real issue https://tinyfn.io/edge

Re:Show HN: TinyFn – Your agent sucks at math on Wednesday February 04, 2026 @08:56AM (#46885827)
Humans are also bad at math! So we created calculators. LLMs should have the same access to tools to give them the best opportunity to succeed

Show HN: TinyFn – Your agent sucks at math

I built TinyFn because I kept watching AI agents confidently get basic things wrong — math, string counting, unit conversions, validations. The classic "how many R's in strawberry" problem, but across hundreds of utility tasks.TinyFn is a collection of 500+ deterministic utility endpoints (math, string ops, hashing, validation, conversions, etc.) that AI agents can call via MCP instead of...

They're building a moat with data. They're building their own datasets of trusted sources, using their own teams of physicians and researchers. They've got hundreds of thousands of physicians asking millions of questions everyday. None of the labs have this sort of data coming in or this sort of focus on such a valuable niche
