A command that loads a separate set of instructions for synchronising one branch or version of a project with another.

Starting the project's approved main-to-v2 synchronisation process while leaving publishing and merge decisions to later checks.

It keeps the synchronisation procedure in one maintained plan, so the command does not need to duplicate or reinterpret it.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 108 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00108
Opus 5.5	$0.00000	$0.00043
Sonnet 5.5	$0.00000	$0.00022
Haiku 4.5	$0.00000	$0.00011

Security

Grade A, and why

sync-main scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Load the sync-main-to-v2 skill and follow it.

That skill materializes the bundled main-to-v2-sync VIPER plan and runs it. It is the only instruction set for this command — do not restate, summarize, or improvise the synchronization workflow here.

Invoking this command is authorization to begin the plan. It is not authorization to push a branch, open a pull request, merge anything, or publish a package. Those remain behind the plan's own gates.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
