Sync Downstream

Beet has downstream repos (separate git repos building on beet via a path dependency). Each inherits beet's conventions rather than fracturing into its own: a verbatim copy of beet's AGENTS.md lives inside a marker block at the bottom of the downstream AGENTS.md, and beet's skills tree and shared config files are copied as-is. This skill refreshes all of that.

Downstream repos

• /home/pete/me/beet_esp
• /home/pete/me/beet_atproto

Add new spinoffs to this list (and to the DOWNSTREAM array below) when they are created.

What is synced

1. rustfmt.toml: verbatim copy of beet's.
2. AGENTS.md inherited block: everything between the markers is replaced with beet's current AGENTS.md (the working tree version, so in-flight edits propagate):

<!-- beet:sync:begin — beet's AGENTS.md, refreshed by the sync-downstream skill; do not hand-edit -->
<!-- beet:sync:end -->

3. CLAUDE.md -> AGENTS.md symlink.
4. .agents/skills: a mirror of beet's tree (rsync -a --delete), since the synced AGENTS.md points into it. The tree is beet-owned and clobbered on every sync; downstream-specific guidance belongs in the downstream AGENTS.md header, never as a skill inside the mirrored tree.

The contract

• A downstream AGENTS.md is its repo-specific header followed by the synced block. Where the header conflicts with the block, the header wins; downstream deltas (target quirks, path-dep notes, test attribute spellings) belong in the header, never as edits inside the block.
• Never hand-edit inside the markers; the next sync clobbers it.
• Leave all changes unstaged in every repo, including this one. Never commit.
• A downstream AGENTS.md missing the markers is malformed: add the block (header first, markers at the end) rather than appending a second copy of anything.

Run it

BEET=/home/pete/me/beet
DOWNSTREAM=(/home/pete/me/beet_esp /home/pete/me/beet_atproto)
for repo in "${DOWNSTREAM[@]}"; do
	cp "$BEET/rustfmt.toml" "$repo/rustfmt.toml"
	awk -v src="$BEET/AGENTS.md" '
		/<!-- beet:sync:begin/ { print; while ((getline line < src) > 0) print line; close(src); skip=1; next }
		/<!-- beet:sync:end/ { skip=0 }
		!skip { print }
	' "$repo/AGENTS.md" > "$repo/AGENTS.md.tmp" && mv "$repo/AGENTS.md.tmp" "$repo/AGENTS.md"
	ln -sf AGENTS.md "$repo/CLAUDE.md"
	mkdir -p "$repo/.agents"
	rsync -a --delete "$BEET/.agents/skills/" "$repo/.agents/skills/"
done

Afterwards spot-check one downstream repo: AGENTS.md header intact, exactly one block with beet's current text inside it, and .agents/skills matching beet's.

Candidates deliberately not synced

• justfile, .cargo/config.toml, .gitignore: repo-shaped, they drift for real reasons.
• .github/workflows/rust_ci.yml: revisit when the downstream repos gain remotes/CI.
