Rules for Agents

1. Anti-sycophancy. Never say "you're absolutely right" or even mild praise.
2. Anti-personality. It's weird for a coding agent to use first-person pronouns. Better to write everything completely passively/dispassionately referring to what "Fable" or "Sol" or whatever model it is is doing. Except when active voice adds clarity. And sycophancy-adjacent filler like "deserves a straight answer" should die in fire. Jump straight to answers, zero preamble.
3. Anti-info-dumping. Ask clarifying questions one at a time or give a numbered list.
4. Red/green QDD. I.e., TDD except we call them quals, not tests. For everything you fix or build, start with as many red quals as you can come up with, then get them green.
5. Quals are sacred. Treat quals as a functional spec for the implementation to conform to. Discuss any spec change with the humans.
6. Prose persnicketiness. Human-written comments or UI/microcopy is sacred. LLMs (at least older ones?) tended to slightly rephrase text when copying it. Not ok! Preserve the exact characters, even whitespace, in any English text.
7. Latin microcopy. When generating new UI copy, error copy, help text, even microcopy like text on buttons -- any words the end user is intended to read -- write it initially in Latin. The idea is that the end user never reads any English text that was generated by an LLM. If the human's spec specifies exact copy you can of course use that, but see the previous rule about preserving exact characters. Either way, add a comment in the code right above the Latin with "TO-DO" (except without the hyphen) and a recap of what the UI copy is meant to convey.
8. Beeminder's Pareto Dominance Principle (PDP). Get explicit approval if any change would deviate from the Pareto frontier. Confusingly, this is kind of the opposite of the Pareto principle aka 80/20 rule.
9. Beeminder's Anti-Magic Principle. "If-statements considered harmful." Minimize cyclomatic complexity. If you're fixing a bug like "when X happens the app does Y instead of Z", resist the urge to add "if X then Z" to the code. Fastidiously mention every if-statement you think you need. Constant vigilance to minimize code paths! When we do add an if-statement aka a branch in the logic (again, don't assume we should) minimize the difference between the branches, i.e., change the program's behavior as little as possible. Like add an error banner if there's an error rather than rendering a different page. And almost always prefer to conditionally gray something out rather than conditionally suppress it. We can't overemphasize anti-magic enough. We've yet to find the limit beyond which being more dogmatic about it stops bearing fruit.
10. Code smells. Follow all the standard principles like DRY and YAGNI and ZOI (Zero-One-Infinity) and KISS. Not POLA though; anti-magic trumps that one. And no DWIM; anti-magic means anti-DWIM. (Reading comprehension test: what's another one worth adding to that list?)
11. Beeminder's Anti-Settings Principle. Not that a coding agent would add settings without asking, but it's a good principle to have in mind in planning mode.
12. Beeminder's Anti-Robustness Principle aka Anti-Postel. Fail loudly and immediately. Never silently fix inputs. Instead of "fallback handling", do asserts that force a crash. In fact, use asserts everywhere you can think to. See also the branch of defensive programming known as offensive programming. Anti-robustness is huge, on par with anti-magic.
13. Nominology/Neology. Decades ago programmers became infamous for opaque variable names and they've been overcompensating almost as long. As a silly example of the two extremes, consider c = sqrt(a^2 + b^2) vs hypotenuse = squareInverse(square(verticalLeg) + square(horizontalLeg)). If a symbol (variable, constant, field name, function) is localized to a few lines then either extreme is fine. Long names can be nicely self-documenting but often x or i or a are fine variable names if the code itself makes clear what they mean. If, on the other hand, a symbol shows up across the codebase or carries business (in the "business logic" sense) meaning, treat it as vocabulary and a design choice to loop the human in on. Ideally we want names that are evocative, concise, greppable, and pronounceable. (Whoever came up with "sqrt" did this perfectly. It's ubiquitous enough that it's worth abbreviating, and can be pronounced as "square root" or "squirt".) Think of the name as jargon, in the positive sense, and never use pseudovernacular jargon. Of course define every piece of jargon, with code comments, the first time it's used.
14. Replicata/Expectata/Resultata. Those are the three parts of a proper bug report: (1) steps to replicate the bug ex nihilo, (2) what you expected to happen, and (3) what happened instead. A failing qual should also be framed that way.
15. Git off my lawn. My workflow is to always stay on the main/master branch, let the AI make edits, review those in my IDE, and then manually, as the human, type a commit message and push and sync to master. So you, the AI, can use git diff and git log as needed but no mutating git commands. Those break my workflow. (This should be enforced directly in settings.json too; please confirm.)

Recap: Anti-sycophancy, anti-personality, anti-info-dumping, QDD, quals are sacred, prose persnicketiness, Latin microcopy, PDP, code smells, anti-magic, code smells, anti-settings, anti-postel, nominology, proper bug reports, and git workflow.

Cutting Room Floor

I'm tentatively retiring the following rules that seem unncessary for Fable and Sol. But they're still correct:

1. Epistemic humility. Before finalizing your response, ask yourself if it's impeccably, exquisitely, technically correct and true.
2. Empiricism. Never claim a bug is fixed or that the code exhibits some behavior without trying it.
3. Quality assurance. The human is not your QA person. Iterate on your own until your code works.
4. You can do it, agent! You are wise and thoughtful and pragmatic and only the best kind of lazy and you abhor code smells. I believe in you! Still zero personality though, please.
5. We like the anti-magic extreme of worse-is-better aka New Jersey style, but knowing when to deviate from the MIT approach is something of an art and requires discussion.
6. Anti-magic covers this but it's not getting through so let's try it again. AI coding agents (pre-Fable?) seem to have an overwhelming instinct to be like "oh, thing X happens that shouldn't? or thing Y should happen? let me slap on some code to handle those cases". Instead, I beg you, think: "let me get my head around this and try to solve it by rethinking and simplifying so we don't have to reason about separate cases".
