A Rule Without An Executor
The capability existed. Nothing ever called it. Eighty-four days later the project was dead. - Patterns · L1
Concluding Absence From One Spelling
A search for a company name returned nothing, so the answer was "there is no record." The record existed under a different spelling of the same name. - Patterns · L1
Mixing The Scales
Six different meanings, all rendered as coloured dots. The reader cannot tell which question a colour is answering. - Patterns · L1
Named For The Moment It Was Created
File names that made sense on the day they were written and are unsearchable a month later. - Patterns · L1
Properties Instead Of A Brief
A task with a perfect set of fields and an empty body is not a task. It is a reminder that something exists. - Patterns · L1
Writing In Someone Else's Name
An agent that drafts email can trivially draft it as a colleague. The capability is one line away and it should never be used. - Patterns · L2
"Zero Problems Found" Means Zero Of What You Measure
A freshness monitor reported all clear while the pipeline behind it was failing. The monitor was right about the only thing it could see. - Patterns · L2
Adding A Rule Without Removing One
Every fix adds a rule. No fix removes one. After a year the instructions are longer than anyone reads. - Patterns · L2
Asking Approval For The Reversible
A gate meant for irreversible decisions gets applied to everything, and the person it protects stops reading it. - Patterns · L2
Drawing Conclusions From Truncated Output
A command printed the first twenty lines and the summary described all of them. - Patterns · L2
Empty Is Not Zero
A weekend of missing exports read as a sales collapse in exactly the window a marketing cut was being tested. - Patterns · L2
Maximum Effort By Default
If the model has a hardest setting, the temptation is to leave it there. It costs more and reasons worse. - Patterns · L2
One Source Is A Hypothesis
A single confident source becomes a stated fact somewhere between reading it and writing it down. - Patterns · L2
Revenue As The Metric
The number everyone reaches for is the one that cannot tell a good week from a bad one. - Patterns · L2
The Decorative Citation
A framework quoted after the conclusion was already reached changes nothing except how the answer looks. - Patterns · L2
The Fallback That Lied
A tool call failed, the agent produced a confident answer anyway, and nobody noticed for a week. - Patterns · L2
The Green Light Nobody Owns
A sign-off said "verified". It was produced by the same process that ran one narrow check. - Patterns · L2
The Header That Counts Itself
A file's summary line claimed twenty-five entries. The file contained twelve. Neither number had been wrong when it was written. - Patterns · L2
Treating llms.txt as a Distribution Plan
Shipping the machine-readable layer is cheap and worth doing. Expecting it to bring readers is a different claim, and the evidence is against it. - Patterns · L2
Two Sessions, One Identifier
Two runs allocated the same record number minutes apart, because both read the next number from a header instead of the data. - Patterns · L2
Year To Date Is Not A Year
Two windows, both labelled annual, that disagree by an entire season. - Patterns · L3
Scoring Sinks The Plumbing
A hundred and twenty ideas were scored on impact. Every idea the reader would see finished near the top; every idea that made those possible finished near the bottom. - Patterns · L3
Verifying In The Wrong Layer
The check passed in the layer above the one where the error lived.
