My copy passed every check. It still read cold.
Six checks passed and my piece still read like a memo. Four numbers explained why. Then a 60-second video script ran 67.5 seconds. copy-engine now writes video scripts that fit every shot.
Why your webinar gets great feedback and nobody buys
Great feedback and no sales is not bad luck. It is a specific failure in a specific section of your presentation — and it is the one that catches the best teachers hardest. How to tell which of the four sections actually broke, instead of rewriting all of them.
I audited my own 102 AI personas. 7 passed.
I ran my persona gate across all 102 avatars in my own catalog. Seven passed. The A/B that followed showed the gap is a prompt gap, not a provider gap, and that is what @di-atomic/persona-builder closes.
Perfect spelling at 20 labels. Missing facts at 8.
Every infographic skill justifies rendering from code the same way: image models garble dense text. I ran eight controlled renders. Spelling was perfect through twenty labels. What breaks at eight is which labels appear at all, and a spellcheck passes that graphic while it is quietly missing one of your facts.
Gmail told me 201. The real number was 35.
Gmail's own result count reported 201 for a true count of 35. The output flag exits 0 and writes nothing. An unsent draft passes attribution checking because its id is genuine. All three return success. Here is the skill I built around not trusting any of them.
A competitor snapshot is NOT a competitor diff
A re-snapshot and a real diff look identical on the page, and nothing in the report tells you which one you are holding. Here is how I made "changed" a server-side fact instead of a writing-discipline problem, and the four numbers from 32 live probes that would each have put a confident wrong figure into a report.
I thought my pricing memo was sourced. 36 claims, 36 unsourced.
I built a script that checks whether every number in a pricing memo cites its source, then ran it on my own first draft. 36 numeric claims, 36 unsourced, FAIL. Getting to zero took four rounds and found four defects in the skill itself.
I checked 30 newsrooms for FOR IMMEDIATE RELEASE. None of them print it.
The most famous line in PR is gone from every modern newsroom I checked, and so is the ### end marker. Not because the press release died, but because its audience changed: answer engines now read it and cite it permanently, which moves the whole quality bar.
I wrote up my best client win. Then legal killed it.
A year ago I wrote up my best client win, then asked for sign-off, and legal killed it — months of proof sunk one signature short. Here's the fix I built into a skill: get the release before the interview, source every number, and let the client hold the pen.
