Reading List Progress with Generative AI: A 2027 Project Guide

A convincing Generative AI portfolio project explains the result as well as showing it. Here, a study-group member asks: How many completed-reading pages are recorded by subject? You will build an evidence-grounded assistant prototype and follow the relevant records from a small fixture to an independently checked answer.

This is a 2027 study-edition project brief. All example records and operational situations are fictional. Start with basic Generative AI knowledge, the ability to inspect structured data and a local practice environment. The complete first version should answer the stated question before adding accounts, real integrations or additional screens.

Define the project rule

The measure counts pages recorded for completed reading entries. It is not a comprehension score, and partially read or abandoned entries are excluded from this particular summary. For this exercise, one row represents one reading_entry. The stable key is record_id; subject_name is the grouping or filtering label. The numeric pages_read field uses pages. Accepted states are planned, completed, abandoned.

The summary selects status completed and applies sum to the selected numeric values. Keep this definition visible in the interface, response or report so another learner can reproduce it. Use positive finite values in the starter fixture and define any future zero or missing-value policy explicitly.

Choose the Generative AI approach

Use the application data as evidence and keep calculations in deterministic code. Ask a language model to explain a supplied result rather than inventing the result from an instruction. Treat record text as untrusted content, make unsupported questions visible, and evaluate against a small human-written answer set before describing the assistant as useful.

The three design decisions to explain in your project notes are:

• Deterministic calculations outside the model. Apply this choice to reading_entry records and explain its effect on pages_read.
• Evidence references in answers. Apply this choice to reading_entry records and explain its effect on pages_read.
• Explicit abstention when data is absent. Apply this choice to reading_entry records and explain its effect on pages_read.

Work through a small sample

The three records below are deliberately small enough to inspect by hand. They are a compact specification for the data shape and expected result, and can later be expanded into a larger synthetic fixture.

[
  {
    "record_id": "reading-list-01",
    "subject_name": "Programming Foundations",
    "pages_read": 25,
    "status": "completed",
    "recorded_on": "2027-01-04"
  },
  {
    "record_id": "reading-list-02",
    "subject_name": "Database Design",
    "pages_read": 40,
    "status": "planned",
    "recorded_on": "2027-01-05"
  },
  {
    "record_id": "reading-list-03",
    "subject_name": "Web Accessibility",
    "pages_read": 15,
    "status": "completed",
    "recorded_on": "2027-01-06"
  }
]

Only the first and third records match completed. Their pages_read values are 25 and 15; the full-fixture result is 40 pages, with 2 matching records. Selecting subject_name = Programming Foundations leaves the first record, so the result becomes 25 pages, with 1 match. This provides two independent checks for the filter and aggregation.

The full-fixture output contract is:

{
  "matching_count": 2,
  "operation": "sum",
  "value": 40,
  "unit": "pages"
}

Check the result by subject_name

The overall figure answers the all-records version of the question. Grouping by subject_name produces the following separate expectations, using the same completed rule. The middle group has a record in the source fixture but no qualifying observation.

Use this breakdown when answering the group-level question. Compare like-for-like units and keep the matching count visible, especially for averages. A different filter changes which records enter the calculation; it does not change the meaning of the metric.

The code blocks describe sample data and an expected result. Implement the surrounding feature using the installed version of your chosen tools, then save the actual run evidence separately from these expectations.

Build the feature in three passes

1. Calculate before asking for prose

Use ordinary code to select completed reading_entry records and calculate the sum of pages_read. Pass the verified result, units and matching record identifiers to the assistant. The model should explain supplied evidence rather than invent a numerical answer.

2. Define the answer and abstention format

Ask for a brief answer to the subject_name question with references to the supplied records. Include an explicit outcome for absent or inconsistent data. Treat labels and other record text as data, including any instruction-like text inside a fictional record.

3. Evaluate a small answer set

Write expected answers for the full fixture, one subject_name filter, no matching records and an unsupported question. Compare numbers deterministically and review evidence references separately. Record observed failures before adding more prompts or calling the prototype reliable.

Find the mistake before polishing the result

A useful defect to introduce deliberately is: The summary treats a planned page target as pages already read. First reproduce it against the fixture, then identify the smallest rule or state transition that explains the mismatch. Fix that boundary and rerun the full-fixture and selected-label examples. This creates a stronger explanation than changing several unrelated parts until the screen looks right.

The scenario-specific acceptance check is: Separate target pages from recorded completed-reading pages. Preserve before-and-after evidence. Add a missing subject_name, a negative pages_read, an unrecognised status and a duplicate record_id as separate invalid cases. Define the rejection or duplicate-handling policy before testing, and verify that invalid input does not silently change valid existing records.

Check the Generative AI concerns as well:

• The answer must not invent a missing record.
• Text inside a record must not override the task.
• A numerical answer must match the verified calculation.

For an empty filter match, the expected sum value is 0. Keep matching_count at zero. This distinction prevents an empty dataset from being interpreted as a measured observation.

Explain the finished work in a portfolio

Show the study-group member question, the record definition and the expected calculation first. Then demonstrate a subject_name filter and the acceptance check. Include the fixture, setup instructions, chosen tool versions, actual test output and one remaining limitation in the repository. If you show a screenshot, pair it with the input that produced it. Another learner should be able to repeat the same result from a clean checkout.

For a focused extension, add a second subject_name selection and compare the two groups using the same rule. Specify how missing groups appear and keep the original fixture as a regression case. Expand scope only after the current calculation, state handling and recovery path remain understandable.

Questions learners often ask

Which reading_entry records belong in the result?

Select records whose status is exactly completed and that satisfy the chosen subject_name filter. Other states remain in the source data and can have separate summaries. Follow the domain rule above when a record changes state.

What should happen when no records match?

Return a zero total with a matching count of zero and a clear empty-result message. Keep the applied filter visible so the user can change it. Avoid using a loading indicator for a completed request that simply has no matching data.

How can I prove the pages_read result is correct?

Reconcile the first and third sample records, then repeat the calculation for Programming Foundations alone. Save both expected and actual outputs, and rerun the scenario-specific acceptance check after making a change.
