docs: explain HitSequence numbering and hot-reload's supported edit shapes - #2380
Merged
Conversation
…hapes Agents were treating HitSequence as 1..HitCount for one marker, and hot-reload --help only mentioned method bodies even though added members in the same file already work. The note and skill text now state both facts in the wording the plan locked. Co-authored-by: Cursor <cursoragent@cursor.com>

Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The updated hot-reload help can still mislead users about which signature changes take effect without compilation, potentially leaving callers on old behavior.

Restrict the summary to signature changes covered by the detailed rules.
Line 4 says that a signature change is supported when the same reload covers the old signature's compiled callers. Lines 168-173 define a different contract for renames and parameter-list changes: they follow the delete rules, and unpatched callers keep the old behavior until uloop compile. The summary can therefore direct users to skip compilation for changes that do not use this gate.
Limit the summary to return-type changes covered by Lines 154-166, or state the delete-rule exception explicitly. After correcting this source, regenerate .agents/skills/uloop-hot-reload/SKILL.md, .claude/skills/uloop-hot-reload/SKILL.md, and cli/common/tools/default-tools.json.
Proposed wording
-description: "... it can also change signatures when the same reload covers the old signature's compiled callers. New types, or members other files must reference, require 'uloop compile'."
+description: "... it can change return types when the same reload covers every live compiled caller of the old signature; renames and parameter-list changes follow the delete rules and may leave callers on the old behavior until 'uloop compile'. New types or members referenced by other files require 'uloop compile'."🤖 Prompt for AI Agents
