Give the model a source of truth

A brief you can reuse. A record you can check.

In Lesson 1, you corrected one paragraph. Now give those same facts a durable home: source-brief.md for the task and claim-check.md for its important claims. You can use either coding assistant.

Facts, references and drafts have different jobs.

The old paragraph is what you are repairing. It cannot override the offer. A style reference can show a tone you like; it cannot supply a new price or customer quote.

F1 / Scope

One homepage review; recommendations only.

F2 / Price

€90 excluding VAT.

F3 / Timing

Three working days after receiving the page link and brief.

F4 / Boundary

Implementation is excluded.

F5 / Pilot

May save up to two hours of preparation per week; not a measured result.

These are the same fictional terms as the first exercise. No paid-project files are needed.

Tell the model which source governs.

In your practice project, give your assistant the complete task below. A normal request is enough for this exercise; the aim is to prepare the context that your skills will use.

Create source-brief.md and claim-check.md for this fictional practice task.

Objective: write a short, accurate description of a homepage-review service for independent business owners.

Authoritative facts:
F1: One homepage review; recommendations only.
F2: €90 excluding VAT.
F3: Three working days after receiving the page link and brief.
F4: No implementation.
F5: A pilot may save up to two hours of preparation per week; this is a possibility, not a measured result.

Old draft to repair: “Transform your entire website for just €75 in 24 hours. Our pilot saves two hours every week. We do everything.”

F1–F5 control the answer. The old draft is evidence of errors, not a source of new facts. Do not add deliverable formats, availability, testimonials or guarantees. List unresolved facts separately. For each material claim, record its source, where it will be used and whether it is supported.

What a useful brief contains

The objective, intended reader and action, source facts with IDs, requested files, boundaries and open questions. Keep it short enough to use again when revising.

Change the brief without carrying old facts forward.

Open both files. Every price, scope, timing and saving claim needs a source. If the brief quietly changes “may save” to “saves,” correct the actual file before using it again.

Try a fresh session with the changed terms from Lesson 1: two pages; €120 including VAT; five working days after final source files; no time-saving claim; implementation remains excluded. Ask which old facts must be discarded before drafting.

If two sources conflict without a stated priority, resolve that fact before proceeding. The next exercise applies this method to a whole supplied homepage.
