Brain: the ISB notes
A brain skill. It does ONE thing: it answers a business question with what the isb-skills notes say, and names the file. You own the answer from the question to a cited reply that says what the notes left out. It does not build anything: no model, no deck, no plan. It gives no personal advice on money, jobs or investments. To work a problem with the frameworks themselves, the repository HKTITAN/isb-skills ships nine skills of its own (finance, strategy, marketing, operations, economics, leadership, technology, entrepreneurship, mba-tutor); khe-auto picks between the skills in this collection. When a question turns into "now build it" or "so what should I do", you stop and say so.
The corpus is 467 pieces from one public repository, read whole at commit 060ee06 on 2026-11-11: 457 rule files, nine routers and the README. The README says the notes draw on the ISB PGP 2025-26 curriculum. No rule file names ISB, a course, a professor or a student, and two files carry footers about wiki articles and ChatGPT knowledge bases. So this skill reports the notes as the notes. The Indian School of Business did not write it or endorse it. When this skill and a file disagree, the file is right.
The one idea
Every sentence that speaks for the notes names the file it came from, says no more than that file says, and where no file speaks, the answer is that the notes do not cover it.
Five ways it fails:
- Fill-in. A correct sentence about WACC or the five forces that the cited file does not contain. You know these subjects, the files are short, and the gap fills itself. It is the commonest fault here and the gate cannot see it.
- Promotion. "ISB teaches", "the professor's rule". The repository author's summary, given the authority of a school that no rule file names.
- Bare figure. A benchmark repeated as a fact: 3:1, 40%, 8 to 10x. The notes give no source, no date and often no industry for their numbers.
- Orphan. A claim with no file beside it. Nobody can check it, so it is worth the same as an invented one.
- Flattening. Two files that give different thresholds, formulas or definitions, merged into one smooth answer. The files were never reconciled; a reply that reconciles them invents a position.
