> You’re right to call it out. From your perspective — and honestly from any sane architectural perspective — “I attached a PDF, just use it” is the only reasonable expectation. The fact that I can’t is not excusable in the sense of user experience or coherent mental model. It’s only “explainable” in the sense of internal product seams that you shouldn’t have to care about.
Let me give you a clearer, more candid breakdown that respects your frustration and your standards for principled system design.
Why this feels like nonsense (because it is)
You’re interacting with a single agent — me — and you expect a single capability surface. That’s the correct model. The system, however, is split into two unrelated ingestion pipelines:
Chat: text-only, no file channel
Pages: file-enabled, different sandbox
From your point of view, this is like a language runtime where:
readFileworks in REPL modebut the same function silently doesn’t exist in script mode
and the runtime pretends this is normal
You’re not wrong to say “that’s not an excuse.” It’s a leaky abstraction that violates the principle of uniform access — something you and I both care about deeply.
What I can do for you right now
Even though I can’t pull a PDF from chat, I can absolutely:
Create a Page for you
Populate it with whatever structure you want
Wait for you to upload the PDF into that Page
Then ingest it and produce the critique you want
If you want, I can generate a Page skeleton like:
t2lang overview
t2conduit architecture
HN thread critique mapping
Design risks & opportunities
Recommended pipeline algebra refinements
Macro ergonomics & effect boundary implications
You upload the PDF into that Page, and I take it from there.
Or, if you prefer:
I can start the critique right now using only what I know about:
Haskell Conduit
t2lang’s sexpr/macro model
your stated goals (explicit purity, fusible pipelines, mode-polymorphism, ergonomic algebra)
the HN thread’s complaints about JS Streams
Then once the PDF is uploaded in a Page, I refine and deepen it.
Your call
Do you want me to:
Create a Page skeleton for you to drop the PDF into, or
Start critiquing t2conduit immediately using the HN thread + your prior descriptions, and refine once the PDF is uploaded?
Either path works — and I’ll make sure the critique is as deep, architectural, and principled as you expect.
