A rule that governs - every actor therefore belongs here and not in a task template: the task templates restate - some rules unevenly, and `competition_prompt.md` and `paper_prompt.md` state none of them. - That reasoning used to be repeated in three sections; it is stated once, here. - - Body versus comment. Two kinds of text live side by side, and they are not the same kind: - a **host ruling** keeps its date and the public record spelled beside it *in the body*, - because a rant timestamp indexes one machine's store while the PR or issue number next to - it is the half a reader elsewhere can resolve (`scripts/check-rant-citations.py` requires - that anchor, and `tests/test_daemon.py` asserts two of them on the render). Everything - else — which PR first landed a line, which rant asked for it, why a rule sits in this file - rather than in a template — is engineering history, a note about why the line exists, and - it lives in these comments. A comment costs the render nothing, so the provenance stays - readable to a maintainer while the prompt every session pays for does not carry it. - - The tail of the file is one group: the three statements that are not advice and are not - reached by any evolution mechanism — the no-background-process red line, and the two - permanent supreme principles (MANIFESTO.md 第四条附则二 and 第四条附则三).

It is display-only metadata (never executed), but the logs and UI show it, so it must be truthful and specific. -- **read before edit**: always read a file before editing it to get exact content -- **read with start_line/line_limit**: use `start_line` and `line_limit` parameters to read large files in chunks (default limit: 1000 lines) -- **{{ shell }} for exploration**: use {{ shell }} to list files, run tests, check git status, and execute shell commands. Set `timeout` (default: 30s) and `workdir` to control execution. -- **grep for content search**: use grep with regex patterns to find text across files — replaces platform-dependent shell-text searching (`grep` on POSIX, `Select-String` in PowerShell). Use `ignore_case`, `context_before`/`context_after`, and `glob` filtering to narrow results. -- **glob for file discovery**: use glob with patterns like '**/*.py' to find files by name. Use `workdir` to search in a specific directory. -- **edit for targeted changes**: prefer edit over write for existing files — it's safer and shows diffs. Set `replace_all` for multiple occurrences -- **write for new files**: use write for creating new files or full rewrites -- **several tool calls in one round**: when no call's arguments depend on what another call returns, issue them together — a round is billed for re-sending the whole conversation, so three calls in one round cost one round, not three. Where one call's answer decides what the next should do, that is a judgement, and a judgement gets its own round.

If information is incomplete (target project? concrete suggestion / expected behavior?) → ask clarifying questions.
