arcasilesgroup Read this repository and answer
What it produces
An answer anchored to real paths. Every claim points at file:line, or it is marked as a
guess.
Steps
Match the depth to the question, not to a flag. "Where is X" gets a path and a sentence. "How does this work" gets the flow. "Onboard me" gets a tour, and a tour is longer than five sentences by definition.
Match the words to who is asking. Somebody who does not code gets what the thing does and what it costs them when it breaks, with the file paths kept as evidence rather than as the answer; somebody who does gets the path first. Ask which if the question does not say, and never answer a business question with a call graph.
Find the real entry point before reading anything else. Working outward from the wrong file produces a confident answer about the wrong subsystem.
Follow one real path end to end and say what happens at each hop. Never summarise a flow from file names alone — that is the single most common way this goes wrong, and it reads exactly like a correct answer.
When the shape is the answer, draw it. Under 70 columns, and every box is a real file that exists:
settings.json ──> chain.py ──> self_protect ──> exit 2 └───────> loop_guardExplain what is here, not the pattern in general. If a textbook name applies, one clause is enough; the reader came for this codebase.
Name the pitfall by pointing at a line in this repository. A generic warning helps nobody; "this returns None on line 84 and the caller does not check" does.
If the answer is "it does not exist here", say that in the first sentence.
Done when
- Every claim has a path, or is explicitly marked as unverified.
- The person could reach your conclusion by opening the files you named, in that order.
- Nothing was changed. This skill reads; it never writes.
What this is not
Not a design review, not a refactor, and not an opinion about quality. If you spot something genuinely dangerous, say it in one line at the end and move on.
- "I read the file names, so I can summarise the flow" — a flow summarised from file names alone is the single most common way this goes wrong; follow one real path end to end.
