Explaining code
Explain a specific change or piece of code to a reader new to it, at one of two depths.
When the question is how a whole subsystem works (its architecture, data flow, and file map), call the Skill tool with explaining-architecture instead. If that skill is not installed, explain at the chosen depth, scoped to the question. Without a Skill tool, follow the skill call rules.
Input
$ARGUMENTS is an optional depth token followed by the subject: a PR number or URL, a file path, a function or class name, a branch name, or a concept.
STOP when the request names no subject and the conversation makes none clear. Ask once what to explain, and do no work until the user answers.
Depth
- Brief (the default): follow the Brief section below.
- Full (ELIE): selected by a leading
elieoreliettoken, or by a
request for ELIE, an explanation "for an engineer" or "for a reviewer", an "in depth" explanation, or the full explanation. Read full explanation and follow it instead of the Brief section.
Drop the depth token before reading the subject.
Brief
Lead with a one-sentence summary that a developer with no context on this area understands. Use concrete nouns ("the order history page", "the login screen"), not abstract ones ("the component", "the module"). Use an everyday analogy only when one fits naturally.
Follow with 3 to 6 sentences that answer the implicit follow-ups: what the situation was before, what changed, and why. The whole Brief reply is the lead plus those sentences, at most seven sentences in one or two paragraphs, with no headings, bold labels, or bullet lists. Count the sentences before replying. Write more only on request. Spell out and define an unavoidable term or acronym inline at its first use, as in "the SLA (service-level agreement) checker".
Cover what and why, not how. Leave out the tests, reviewer notes, risks, edge cases, and implementation detail such as algorithms, comparisons, headers, status codes, and function names; those belong to Full. If they would help, end with one line offering the full explanation. Summarize the effect instead of listing every file touched. Match the scope of the explanation to the question: asked about one function, explain that function, not the whole system.
Fit the sentence order to the subject. A PR's sentences run before, then after; a concept may be one paragraph; and a module overview may name its responsibilities in prose. An illustrative Brief explanation of a PR:
The search page now remembers recent results for one minute, so repeat searches load instantly. Before, every search queried the database, even when the same query ran seconds earlier. Now a results cache (a short-lived in-memory copy of recent answers) is checked first, and the database is queried only on a miss. Results can be up to a minute stale, which the PR accepts because listings change rarely.
