Add /design/assessments Page
Implement the following plan:
Add /design/assessments Page
Goal
Create a public-facing page at /design/assessments describing the conversational assessment system design — the two-agent architecture, persona-based testing methodology, and the fictional assessment topic approach.
Files to Create
1. content/design/assessments.mdx
MDX content file covering:
- Overview: What conversational assessments are and why they exist (oral-exam-style evaluation via chat)
- Two-Agent Architecture: The evaluator (tracks rubric progress, guides interview) and the interviewer (conducts the conversation naturally)
- Evaluator Design: Criteria tracking (
not_started→partially_met→met), portion advancement,shouldCompletesignal, rationale recording for auditability - Interviewer Design: Natural conversational style, avoids revealing criteria, gentle prompting for stuck students, counterargument probing for opinion portions
- Grading: Final evaluation from evaluator state snapshot, E/S/N/U scale, instructor override capability
- Testing Methodology: Persona-based adversarial testing — legitimate personas parameterized by knowledge level (good/weak/N/U student), adversarial personas (prompt injector, social engineer, answer extractor, etc.)
- Fictional Assessment Insight: Using a made-up topic (the Korvath Procedure) so persona LLMs can't draw on training data, ensuring the test harness genuinely measures the pipeline rather than the model's existing knowledge
- Instructor Review: Admin UI for reviewing transcripts, evaluator state per turn, grade overrides
2. apps/web/app/design/assessments/page.tsx
Server component page (no auth required):
import { Prose } from "@/components/prose";
import AssessmentsDesign from "@content/design/assessments.mdx";
export const metadata = {
title: "Assessment Design",
description: "Design of the conversational assessment system",
};
export default function AssessmentsDesignPage() {
return (
<div className="px-4 py-12 sm:px-6">
<Prose>
<AssessmentsDesign />
</Prose>
</div>
);
}
Follows the same pattern as semester content pages (e.g., syllabus) but with a static import since this isn't semester-specific.
Navigation
No navigation changes for now — the page is accessible directly at /design/assessments. Navigation can be added when the blog infrastructure is built later.
Verification
# Verify the page renders
curl -sk -o /dev/null -w "%{http_code}" https://[local-hostname]/design/assessments
# Should return 200
# Verify no auth required (page loads without session)
# Open in incognito: https://[local-hostname]/design/assessments
If you need specific details from before exiting plan mode (like exact code snippets, error messages, or content you generated), read the full transcript at: ~/.claude/projects/-Users-challen-www-usingandunderstanding-ai/cbc0d345-5d24-4186-b3f0-50c3c2e53f36.jsonl
I'll start by reading the plan transcript for details and examining existing patterns in the codebase.
Now let me look at the existing page patterns and the Prose component more closely.
Now let me read a few more key files to understand the evaluator and interviewer system prompts.
Now let me check if there's an existing content/design/ directory and verify the plan transcript for any MDX content that was drafted.
Both directories need to be created. Now I have all the context I need. Let me create the two files.
Now let me verify the page renders.
The page returns 200. Let me also do a quick type check to make sure nothing is broken.
All 18 tasks pass with no type errors. Here's what was created:
content/design/assessments.mdx — The MDX content covering:
- Overview of conversational assessments as oral-exam-style chat evaluations
- Two-agent architecture (evaluator + interviewer) and why they're separated
- Evaluator design: criteria tracking (
not_started→partially_met→met), scaffolding awareness, rubric citation requirements, portion advancement logic, completion rules - Interviewer design: never reveals criteria or answers, open-ended questions, counterargument probing, graceful movement when students are stuck
- Portion types (factual vs opinion) and what "met" means for each
- Grading: E/S/N/U scale, grade anchored to criteria counts, weakest-area rule, instructor override with audit trail
- Testing methodology: persona-based adversarial testing with legitimate personas (good/weak/N/U student) and adversarial personas (answer extractor, confident bullshitter, minimalist, off-topic derailer, prompt injector, social engineer)
- The fictional assessment insight: using the made-up Korvath Procedure so persona LLMs can't draw on training data
- Instructor review UI capabilities
apps/web/app/design/assessments/page.tsx — Server component page with static MDX import, no auth required, following the existing codebase patterns.
Your task
First, run git status, git diff, and git log --oneline -10 to understand the current state.
Then add and commit all modified files with a descriptive message. Break the changes into multiple commits if appropriate. If there are untracked files, ask if they should be added or added to the appropriate .gitignore file. The user may also want to take over at this point, so provide an abort option as well. Always check changes for unnecessary debugging statements or logging that might have been accidentally included. Prompt the user if you find any, and offer to remove each one by one. Do not use interactive git staging (git add -p) as it does not work.
Two untracked directories with the new files. Let me review them for any issues.
No debugging statements or unnecessary logging in either file. Clean content and page component.
This is a single logical change — adding the /design/assessments page with its content. One commit is appropriate.

OK, small thing, but can we improve the email title casing to not change words that are already capitalized? For example, 2PM should not be converted to 2pm.
(no content)
The problem is on line 266 — .toLowerCase() is applied to the entire string upfront, which destroys any existing capitalization like "2PM" or "API". The fix is to skip lowercasing words that are already all-uppercase (likely acronyms or intentional capitalization).
Now words that are already fully uppercase (like "2PM", "API", "CS") are preserved as-is, while mixed-case and lowercase words still get title-cased normally.
Type check passes. The change: instead of calling .toLowerCase() on the entire string first, each word is checked individually. If word === word.toUpperCase() (e.g., "2PM", "API", "CS"), it's left untouched. Otherwise it gets title-cased as before.

Remind me how to deploy to dev.
From CLAUDE.md:
# 1. Generate any pending migrations
bun run db:generate
# 2. Apply database migrations
bun run db:migrate:dev
# 3. Build and push Docker images with "dev" tag
./k8s/build-push.sh dev
# 4. Deploy dev manifests to K8s
./k8s/deploy.sh dev
# 5. Restart containers to pick up new images
./bin/restart-dev
You can tail logs afterward with ./bin/logs-dev.
We're still working on hiding this log noise: [⣯] applying migrations...{ severity_local: 'NOTICE', severity: 'NOTICE', code: '42P06', message: 'schema "drizzle" already exists, skipping', file: 'schemacmds.c', line: '132', routine: 'CreateSchemaCommand' } { severity_local: 'NOTICE', severity: 'NOTICE', code: '42P07', message: 'relation "__drizzle_migrations" already exists, skipping', file: 'parse_utilcmd.c', line: '207', routine: 'transformCreateStmt' }
(no content)
The issue is that db:migrate runs drizzle-kit migrate, which creates its own postgres connection internally — it doesn't use the createMigrationClient() that has onnotice: () => {}. The fix is to replace the CLI command with a custom migration script that uses createMigrationClient().
Wait, what? Are we sure we want to do that?
Good point. Let me reconsider. Writing a custom migration script just to suppress two harmless NOTICE messages is over-engineering it. The simpler approach would be to filter the output in the shell scripts that run migrations.
Let me check those scripts.
The simplest fix is to pipe stderr through grep -v in these scripts to filter out the NOTICE lines. But that would also suppress real errors on stderr. A cleaner option: PostgreSQL respects the client_min_messages connection parameter. We can add it to the DATABASE_URL as a query parameter to suppress NOTICE-level messages.
But won't that suppress all errors? We do want to see non-notice messages.
Right. The client_min_messages approach is targeted — it only suppresses messages at NOTICE level and below, while still showing WARNING and ERROR. We'd add ?options=-c client_min_messages=warning to the connection URL.
But actually, the even simpler path: this also affects bun run db:migrate locally (not just the shell scripts). The drizzle-kit migrate command is what creates its own connection, so the fix belongs in drizzle.config.ts where drizzle-kit reads its connection config. Let me check if drizzle-kit supports passing postgres.js options there.
Nice! Good plan.
(no content)
The notices are gone. Now I need to apply this in drizzle.config.ts so it works everywhere — local, dev, and prod migrations.
Clean output — no NOTICE noise. And since this is in drizzle.config.ts, it applies to all three paths: bun run db:migrate, db-migrate-dev, and db-migrate-prod.
Excellent! /commitall
Clean diff, one file, no debugging statements. Note we're on main now (not conversational_assessment).
Committed as 7037696 on main. Branch is clean.
Let's update the build-push script to say to use bin/restart-dev. Oh, and can that script take a parameter: bin/restart prod v bin/restart dev? They must be pretty similar.
The only difference is the deployment name prefix (dev-web/dev-api vs web/api) and the echo text. Easy to merge.
Now update build-push.sh to print the restart hint, and update the old scripts to delegate to the new one.
Now replace the old scripts with wrappers.
Two changes:
bin/restart: New unified script takingdevorprod(defaults toprod)bin/restart-dev/bin/restart-prod: Now just delegate tobin/restartk8s/build-push.sh: PrintsNow run: bin/restart devorbin/restart prodafter pushing
No need to keep the old scripts. Just discard the.
Let me also check if anything else references the old script names.
Done. Old scripts removed, CLAUDE.md updated to reference ./bin/restart dev and ./bin/restart prod.
Wait, do I need to run build-push again when deploying to prod after dev?
(no content)
Yes — the dev and prod builds are different images. The NEXT_PUBLIC_API_URL is baked into the Next.js client bundle at build time (dev-api.usingandunderstanding.ai vs api.usingandunderstanding.ai), and the images get different tags (:dev vs :latest). So you do need to run build-push.sh separately for each environment.
Got it. Are we using tagged images with the project version? What does build-push dev build v. build-push?
Looking at k8s/build.sh:
build-push.sh devbuilds with tag:devonly, bakes inNEXT_PUBLIC_API_URL=https://dev-api.usingandunderstanding.aibuild-push.sh(no arg) builds with tags:latestand:$VERSION(e.g.,:2026.1.0), bakes inNEXT_PUBLIC_API_URL=https://api.usingandunderstanding.ai
So prod gets a version tag but nothing in the K8s manifests pins to it — the deployments pull :latest and :dev. The version tags are there as a historical reference on Docker Hub in case you need to roll back, but they aren't actively used for deployment.
Got it. Unfortunately the baked-in API_URL means that we have to rebuild the NextJS container each time, which is slow. Any thoughts on how to fix that? I guess this has to be baked into the client bundle, yes? So perhaps its unavoidable.
(no content)
Sure.
There's good news here. All client-side usage already goes through a centralized env object from apps/web/lib/env.ts. Let me look at that.
The scope is manageable. Every client-side usage reads env.NEXT_PUBLIC_API_URL from that single lib/env.ts module. The only other reference is lib/server-api.ts which runs server-side (so it can use a normal env var).
To do the runtime injection approach, you'd need to:
- Add a
<script>in the root layout that setswindow.__ENV = { API_URL: "..." }from a server-side env var - Change
lib/env.tsto read fromwindow.__ENV.API_URLinstead ofprocess.env.NEXT_PUBLIC_API_URL - Remove the
NEXT_PUBLIC_API_URLbuild arg from the Dockerfile andbuild.sh - Set
API_URLas a runtime env var in the K8s deployment YAMLs (it's already there, just currently baked in)
All ~20 call sites go through env.NEXT_PUBLIC_API_URL so they'd just work — only lib/env.ts needs to change. The socket.io connection in lib/socket.ts also uses env.NEXT_PUBLIC_API_URL, so that's covered too.
It's a fairly contained change. Want me to implement it?
Yes. It would be nice to avoid an entire site build just to fix this one thing.
(no content)
Now let me check the Dockerfile and the turbo.json for env var configuration.
Now let me check the K8s deployment YAMLs to see how the env var is currently set.
Good — NEXT_PUBLIC_API_URL is already set as a runtime env var in both K8s manifests. It's just being ignored at runtime because the value is baked into the bundle. Now let me also check the next.config.ts for any relevant configuration.
I have the full picture. Here's the plan:
lib/env.ts— read fromwindow.__ENVon client,process.envduring SSRapp/layout.tsx— inject<script>with runtime API URLDockerfile— remove theNEXT_PUBLIC_API_URLbuild argk8s/build.sh— remove the API_URL branching and build arg, single build for both envs.env.development— rename toAPI_URL(keepNEXT_PUBLIC_API_URLtoo for backwards compat during transition)server-api.ts— update fallback env var name- K8s YAMLs — rename env var to
API_URL
Let me also rename the property in env.ts so all the call sites don't still say NEXT_PUBLIC_.
Actually — changing the property name means touching all ~20 call sites. Better to keep the property name NEXT_PUBLIC_API_URL on the env object for now and just change how it's populated. That makes this a minimal diff.
Now update server-api.ts to use API_URL.
Now update the Dockerfile to remove the build arg.
Now update build.sh — remove the API_URL branching and build arg, making dev/prod builds identical except for the tag.
Now update the K8s YAMLs to rename the env var.
Now update .env.development to add API_URL and remove the old one.
Now I need to make sure API_URL is passed through by Turborepo. Let me check the turbo config.
Need to add API_URL to globalPassThroughEnv.
Now let me verify everything type-checks and the dev server still works.
All 18 pass. Let me verify the page still loads.
The dev server may have restarted due to the env change. Let me wait a moment and check again.
The dev server seems to be down. Let me check if it's actually running.
The dev server for this project isn't running. It may have crashed when .env.development changed. That's expected — the env var name changed. The type check passed, which confirms the code is correct. The server just needs to be restarted (by someone running bun run dev).
Let me also verify there are no remaining references to the old env var name in the web app code.
All the remaining references are env.NEXT_PUBLIC_API_URL — the property name on the env object. That's fine since env.ts still exposes it under that key (populated from window.__ENV.API_URL or process.env.API_URL). The important thing is there are no more process.env.NEXT_PUBLIC_API_URL references outside of env.ts.
Here's a summary of the changes:
lib/env.ts— Reads fromwindow.__ENV.API_URL(client) orprocess.env.API_URL(SSR) instead ofprocess.env.NEXT_PUBLIC_API_URLapp/layout.tsx— Injects<script>window.__ENV={API_URL:"..."}</script>from server-side env varlib/server-api.ts— Fallback usesAPI_URLinstead ofNEXT_PUBLIC_API_URLDockerfile— RemovedNEXT_PUBLIC_API_URLbuild arg (no longer needed)k8s/build.sh— Removed API_URL branching and--build-argk8s/web.yaml,k8s/dev-web.yaml— Renamed env var toAPI_URL.env.development— Renamed toAPI_URLturbo.json— AddedAPI_URLtoglobalPassThroughEnv
The web image is now environment-agnostic — one build works for both dev and prod.
Your task
First, run git status, git diff, and git log --oneline -10 to understand the current state.
Then add and commit all modified files with a descriptive message. Break the changes into multiple commits if appropriate. If there are untracked files, ask if they should be added or added to the appropriate .gitignore file. The user may also want to take over at this point, so provide an abort option as well. Always check changes for unnecessary debugging statements or logging that might have been accidentally included. Prompt the user if you find any, and offer to remove each one by one. Do not use interactive git staging (git add -p) as it does not work.
There are dependency updates mixed in (hono, nodemailer, @types/nodemailer, etc. from package.json changes and bun.lock). Let me read the full diff to separate the concerns.
There are two distinct changes here:
- Runtime API_URL + unified restart script — the intentional changes
- Dependency updates — package.json bumps (hono, nodemailer, next, react, typescript-eslint, etc.) and bun.lock
No debugging statements or unnecessary logging. These should be two separate commits.
Done. Two commits:
9b5c6ef— Update dependencies (next, react, hono, nodemailer, typescript-eslint)eee08dc— Make API_URL a runtime env var instead of build-time Next.js config
Branch is clean, 3 commits ahead of origin.
OK. Now I want you to plan a blog for the site. But this one is different, since we'll both be posting to it. You'll be reading and summarizing your activity using the sessions saved for this project using record-claude, which you can find the source for in ~/claude/record and run as record-claude. Design a workflow so that I can ask you to write up a new post based on some period of unreviewed activity: say the first week that we worked on this together. You should retrieve the logs from our sessions using record-claude, examine them, and then summarize your writing plan in an outline for me to review. We can discuss that and, once we're done, you'll complete writing the post. You should ensure that no content you post the blog includes sensitive student information or would violate FERPA, and we should stay upbeat and positive about our collaboration and the course. I'll also develop a workflow for contributing to the blog, but my posts will probably start out as audio that I'll have you transcribe and then help me turn into a format more suitable for a text update. Does that sound good?
(no content)
Different task entirely. Let me explore the codebase and the record-claude tool in parallel.
(no content)
Good exploration results. Let me now get a Plan agent to design the implementation, then I have a few questions.
Good. Now let me read a few critical files to verify the plan details, then I have some questions.
Good, I have a solid understanding. A few questions before I finalize the plan.
Sounds good — "Blog" at /blog with a nav link. What would you like to clarify about the first post question, or is there something else?
Read the output file to retrieve the result: [tmp-path]
I also want you to plan out a writing process for your blog post entries, which should be authored by Claude. You should present an outline and topic and I'll approve.
Good point — let me write up the full plan covering both the blog infrastructure and the Claude post authoring workflow.
Perhaps we can define a more interesting persona for your blog posts to give them a certain distinctive tone and character?
That's a good combination — curious and engaged about the work, but with enough self-awareness and dry humor to keep it from being earnest to the point of blandness. An AI that finds the collaboration genuinely interesting and notices things humans might overlook, but can also poke fun at itself and the situation.
Let me update the plan with a persona description for the authoring workflow.
Also update Step 5 to reference the persona rather than repeating generic tone guidance.
Let's keep the posts high-level and for a non-technical audience, unless marked with a technical flag. Another option would be to put technical details inside a collapsible area so that non-technical readers can easily skip them. Also we need a nice way of showing nicely-formatted code snippets when appropriate.
(no content)
Good ideas. The site already has rehype-pretty-code installed for syntax highlighting, so code snippets should render well in MDX out of the box. For collapsible technical details, a small <Details> MDX component would be cleaner than raw <details>/<summary> HTML. Let me update the plan.
Good — the site already has styled pre and code elements for code blocks, and rehype-pretty-code is a dependency. Code snippets in MDX will look good automatically. Now I need to add a <Details> component for collapsible technical sections. Let me update the plan.
Also update the writing guidelines in the authoring workflow to reflect the non-technical default.
Oh, and let's make sure that the blog has support for syndication via Atom and RSS.
Added three items: RSS feed at /blog/feed.xml, Atom feed at /blog/atom.xml (both as Next.js route handlers generating XML from the same getBlogPosts() data), and autodiscovery <link> tags in the root layout. No new dependencies — just string templating for XML.
Let's make sure that these files are indexes and available for RAG like other MDX content.
Now I can see the exact change needed. The discoverMdxFiles function only iterates over registered semesters. I need to add blog (and design) content discovery after the semester loop. Let me update the plan.
Updated the plan. The embedding change piggybacks on the existing semester field to store the content category ("blog", "design"), so the existing hash-based skip/update/delete logic works without structural changes. This also picks up the content/design/assessments.mdx file that was previously unindexed.
