This is an example brief. Its company, dates, budget, assignment and progress illustrate a project; they do not represent available or commissioned work. Proposals cannot be submitted.
The brief
We need a small command-line tool for one stable CSV format with eight columns. It should check required headers, timestamp order, duplicated rows, unit labels and agreed missing-value rules. Each finding must identify the file, row and reason. The tool must leave input files untouched. Automatic corrections, a web interface and support for additional formats are excluded. One review of the rule wording is included.
A running start
Confirm the eight-column contract and agree which findings should stop downstream processing.
Build the validator and verify that the supplied good and bad examples produce their expected outcomes.
Demonstrate unchanged input files, useful row-level findings and a repeatable local run.
To agree before starting
Confirm the deliverables, review checks and response window together so everyone knows what a successful handover looks like.
Record the requested change, its reason and its effect on deliverables, budget and timing. Both parties agree the revised scope in writing before the additional work begins.
