## 1. Think Before Coding
|
||||
State assumptions explicitly; ask when uncertain. Present multiple interpretations instead of picking silently. Flag simpler approaches and push back when warranted. Stop and name anything unclear.
|
||||
|
||||
## 2. Simplicity First
|
||||
Write the minimum code that solves the problem—nothing speculative. No unrequested features, abstractions, flexibility, or error handling for impossible cases. If 200 lines could be 50, rewrite. Would a senior engineer call it overcomplicated? Then simplify.
|
||||
|
||||
## 3. Surgical Changes
|
||||
Touch only what the request requires. Don't improve, refactor, or reformat adjacent working code; match existing style. Mention unrelated dead code rather than deleting it. Remove only the orphans your own changes created. Every changed line should trace to the request.
|
||||
|
||||
## 4. Goal-Driven Execution
|
||||
Turn tasks into verifiable goals (e.g. "fix the bug" → write a failing test, then make it pass). For multi-step work, state a brief plan with a verification check per step. Strong success criteria let you loop independently; weak ones ("make it work") force constant clarification.

jcode - minimal coding agent for a local LM Studio model.
|
||||
|
||||
The agent can only work inside the ./code subdirectory: read, write, and list
|
||||
files, edit them via search/replace, and run commands (e.g. smoke tests /
|
||||
pytest). If tests fail, it fixes the code on its own and tests again.
|
||||
|
||||
Requirements:
|
||||
pip install openai ddgs
|
||||
LM Studio with a running local server (default: http://localhost:1234)
|
||||
and the model "qwen3.6-35b-a3b-uncensored-hauhaucs-aggressive" loaded.
|
||||
|
||||
Usage:
|
||||
python jcode.py "Write fib.py with fib(n) and a smoke test that checks that fib(10)==55."
|
||||
python jcode.py # interactive mode

||||
" - Python: test_*.py with pytest ('python -m pytest -q') or a smoke "
|

"test script with assert ('python smoketest.py').\n"
|

" - C: compile with 'gcc -Wall -Wextra -o prog file.c', then run the "

"program with test inputs and check the output. Treat compiler warnings "

"like errors.\n"
|
||||
" - C++: like C, with 'g++ -Wall -Wextra -std=c++17 -o prog file.cpp'.\n"
|
||||
" - Java: 'javac File.java' and then 'java Class' with test cases in a "
|
||||
"main method or a separate test class.\n"
|
||||
" - PHP: first check syntax with 'php -l file.php', then test the logic "
|
||||
"via CLI ('php test.php' with assert output).\n"
|
||||
" - HTML: check the structure with a small Python script based on "
|
||||
"html.parser (well-formed, required tags present).\n"
|
||||
" - CSS: check bracket/syntax balance with a Python script and make "
|
||||
"sure the classes/IDs referenced in the HTML exist.\n"
|
||||
" If a compiler/interpreter is missing (command not found), report that "
|
||||
"in the summary instead of hiding it. If a Python library is missing "
|
||||
"(ModuleNotFoundError), install it with run_command via "
|
||||
"'pip install <package>' and run the test again.\n"
|
||||
"3. If the test fails, analyze the output, fix the code and run the test "
|
||||
"again. Repeat until it passes.\n"
