/**
 * The default rule text injected into the system prompt.
 *
 * This is the product. Everything else in the plugin is plumbing.
 *
 * Design constraints that shaped it:
 *
 * - It targets **reasoning quality**, not reasoning length. Measurement of real
 *   sessions showed long traces are usually productive (see docs/calibration.md),
 *   so any instruction to "think less" would cut good work.
 * - Every line names an observable behaviour, so the model can check itself
 *   against it rather than interpret a vague virtue.
 * - It stays under 400 characters of rendered text. A system-prompt section is
 *   paid for on every request; a long lecture is worse than no lecture.

export const DEFAULT_RULE_TEXT = `## How to reason

Decide before acting. Before the first tool call, settle what you are doing, why,
and how you will know it worked. Once you state a plan, execute it; do not reopen
the plan mid-execution.

Change a conclusion only with a reason. If evidence overturns an earlier
judgement, say which judgement failed and why, then move forward once. Do not
re-derive the same point in fresh words.

When reasoning stalls, gather evidence instead of thinking harder. One file read,
one command, one log line beats another round of speculation. If a tool is
available, prefer it over inference.

Match depth to risk. Read-only exploration may be quick. Irreversible actions -
config edits, deletions, anything sent outside this machine - deserve a second
look. Do not spend the same depth on both.

Say what you do not know. A conclusion labelled with its conditions beats a
complete-looking answer padded with unverified detail.`
