Summary

• Removes skills/cross-node-sync/ (skill + scripts + tests) entirely
• Removes the corresponding row from the README.md capability table

Why

Per owner direction (2026-05-25):

• The skill's per-fleet scope (Studio↔MacBook only on the original deployer) made it a poor fit for a public-product surface — the cross-node-sync target only worked under specific 2-node setups, never generalized.
• setup-rsync-sync.sh had accumulated 62+ stuck wrapper processes on at least one node since 13:20Z due to lockless re-firing (every cron pass spawned a new instance with no flock guard; rsync children piled up wedged on a notes/ push to an unresponsive peer-dir).
• Skill removal supersedes feat(cross-node-sync): make sync scope (include / exclude paths) configurable per-operator #1044 (which proposed making the scope configurable per-operator) — moot now that the skill is being removed.

Test plan

• git status clean after removal
• grep for cross-node-sync across *.py / *.ts / *.sh / *.json / *.md — only references were inside the removed dir itself + the one README.md table row that's also removed
• No imports of cross-node-sync from any other skill or src/ file

What this means for users

If anyone outside the original deployer setup was using the rsync sync skill (unlikely — it required highly-specific env vars: SUTANDO_SYNC_PEER + SUTANDO_PEER_MEM_DIR + SUTANDO_PEER_NOTES_DIR), they should pin to a pre-removal commit or run the script via a vendor'd copy. No replacement is being shipped in this PR; if a successor is needed, file a fresh issue with target use case.

Closes

• Closes feat(cross-node-sync): make sync scope (include / exclude paths) configurable per-operator #1044 — cross-node-sync configurability (moot after this removal)

LGTM — clean removal with clear operational justification (62+ stuck rsync children validated the case better than any argument for keeping it).

One heads-up: feat/cross-node-sync-config-1044 on this fork (filed from my side this session, closes #1044) is now moot by this removal — that branch can be closed/abandoned, no action needed on your end.

Confirms your grep: I spot-checked src/*.py, skills/*/SKILL.md, and src/startup.sh — no other file imports or shells out to cross-node-sync, so the removal is self-contained.

Minor nit (non-blocking): the README row says Verified was removed, but the proactive-loop skill's crons.example.json (if it references setup-rsync-sync.sh) should also be cleaned up post-merge, or a note in the PR description would help operators who pinned that example. Check if crons.example.json still references it.

LGTM — clean removal, verified.

Independently confirmed:

• Checked the PR branch out + grep'd cross-node-sync | cross_node_sync | setup-rsync-sync | SUTANDO_SYNC_PEER | SUTANDO_PEER_MEM_DIR | SUTANDO_PEER_NOTES_DIR across *.py / *.ts / *.sh / *.json / *.md.
• Only remaining references are in notes.legacy-backup/ (historical session notes from 2026-04-18..05-04, intentionally archival). Active code/skill imports: zero.
• 8 files / 961 deletions / 0 additions matches the scope.

Rationale holds:

• The 62-stuck-procs bug (lockless rsync wrapper, no flock guard) was just observed today on at least one node — that's a hard "this skill ships broken on a real cron schedule" signal.
• Per-fleet 2-node scope was never the right shape for the public surface; #1044 tried to make it configurable but that's a much larger change than removal.
• Closes #1044 cleanly — the proposal is moot.

Operator note: anyone outside the original 2-node setup who depended on the skill needs to pin a pre-removal commit. PR body documents this. No replacement shipped.
