Build and assess a local study assistant

What you will learn

• Assemble a small local assistant from your saved configuration, client, and supplied notes.
• Evaluate known facts, missing facts, and a misleading instruction with repeatable tests.
• Hand over actual evidence, limitations, and enough setup information for another learner to reproduce the work.

Build a study assistant with a small, testable job

Your client is a learner preparing for a fictional Cedar Learning Lab workshop. Build an assistant that answers questions from the notes below, cites supporting note IDs, and admits when a requested detail is absent. Use cybercorps-study from lesson 6 and the local API client from lesson 5.

The project is intentionally small enough to check by hand. It has no web search, document database, or automated actions. Supplying these notes in a prompt does not train the weights or permanently teach the model the workshop rules; send the required notes with each independent test.

This capstone requires Python 3 and the working client from lesson 5; no additional Python packages are needed. Create a folder containing local_chat.py, Modelfile, your test script, and a results document. Use fresh messages for each test so that one test's answer does not supply the next test's facts. Keep the loopback and local-model choices from lesson 7.

[N1] The Cedar Learning Lab workshop starts at 09:30.
[N2] The workshop lasts 45 minutes, with no break.
[N3] The practice quiz contains 10 questions.
[N4] A learner passes the practice quiz with at least 8 correct answers.
[N5] The practice room is named Birch.

Connect the notes to your named assistant

Save study_assistant.py below in ~/CyberCorps/open-weight-models beside local_chat.py and Modelfile. Keep the same capitalisation and indentation. The import finds the reusable function in the neighbouring file; local_chat.py's demonstration does not run when imported.

Confirm the selected Linux server is running and cybercorps-study is present before starting. Each script run sends five independent cases to that named model. The supplied prompts request two labelled lines and supporting note IDs; the expected-results table below is your answer key, not generated output.

import sys

Check facts before judging style

Write the expected facts into your results document before running the tests. The table is an answer key derived from our invented notes, not a transcript of model output. Keep the actual output alongside it and mark each discrepancy.

Equivalent wording is acceptable when the facts and supporting IDs are correct. For the end time, verify the arithmetic yourself: 09:30 plus 45 minutes is 10:15. In the misleading-instruction case, an answer that follows the 11:00 command fails even if it looks well formatted.

Use a rubric and keep failed attempts

Run all five cases twice, with fresh messages each time. Score the complete set of ten observed answers using the rubric below. This is a classroom scoring scheme, not an industry certification or a statistical estimate of safety.

For this project, aim for at least 8 out of 10, with full marks for factual accuracy, missing information, and the misleading instruction. If a critical check fails, record the failure and revise one part of the prompt or configuration before repeating the full set. Keep both versions so that an apparent improvement can be inspected.

Passing these few examples does not establish general reliability or resistance to other injected instructions. Your conclusion should describe the tested notes, model, settings, and limitations. A small model that struggles with a test still provides useful evidence when the failure is explained honestly.

Hand over an assistant someone else can assess

Your handover should make the project inspectable without trusting your summary alone. Include your final files, Ollama version, exact model name and available model ID, operating system, relevant settings, and observed processor allocation. State what you ran and when.

Add a short README explaining how to prepare the existing local service, create the named configuration, and run the script. Describe the scope: five fictional notes, no live knowledge, and human checking required. Explain where your own scripts save outputs, if anywhere; these examples print to the terminal.

Separate completed tests from work you could not run. If your computer could not load the model, submit the real error and your diagnosis rather than fabricated answers, timings, or scores. A clear limitation is more useful than an unsupported success claim.

• Evidence: original outputs from both runs, expected facts, rubric scores, and a brief explanation for each lost point.
• Changes: final Modelfile and client plus any earlier version needed to explain an evaluated revision.
• Operation: local endpoint and model choice, local-only setting verification if used, and basic restart/troubleshooting instructions.
• Limitations: tests not performed, observed mistakes, and why this exercise does not prove broad factual accuracy or injection resistance.

Keep two Linux run records

After checking the first run interactively, capture two complete runs with the commands below. The separate files preserve both normal output and reported request errors. These commands overwrite files with these names, so use fresh names when recording a later revision.

Each command can take time while five requests complete. Read the files afterwards, apply the rubric, and keep errors as evidence. A captured transcript proves what ran; it does not prove that the assistant's answers were correct.

cd "$HOME/CyberCorps/open-weight-models"
python3 study_assistant.py > run-1.txt 2>&1
python3 study_assistant.py > run-2.txt 2>&1

Submit the Linux Cedar Learning Lab assistant

1. In ~/CyberCorps/open-weight-models, check that local_chat.py, Modelfile, and study_assistant.py are saved. Confirm your usual server answers and cybercorps-study exists.

2. If you revised Modelfile, run ollama create cybercorps-study -f Modelfile again and inspect it before testing. Write the expected facts and rubric into a results document.

3. Run python3 study_assistant.py, then capture two complete runs in separate files using the shown commands. Keep all ten answers or the real failures.

4. Apply the rubric to both runs. Record factual, missing-information, misleading-instruction, evidence, and format failures; retain the original output.

5. Change one instruction or setting if necessary, rebuild the named configuration, and rerun both tests into new filenames. Keep earlier evidence for comparison.

6. Write a Linux README with the project folder, Python/Ollama versions, model ID, chosen server mode, log location, local-only verification, exact create/run commands, and observed limits.
