A migration skill moves legacy rp1 project files and database records into the current layout. It first detects whether migration is needed, previews the planned changes, and requires confirmation before changing anything.

Use it to inspect migration status, preview file and database changes, and migrate an rp1 project from its main repository.

It provides a controlled path from an older project structure to the current one while reducing the chance of changing the wrong repository or applying changes unexpectedly.

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	$0.00018	$0.00515
Opus 5.5	$0.00007	$0.00206
Sonnet 5.5	$0.00004	$0.00103

Security

Grade A, and why

rp1-migrate 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 19d 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

Migrate Legacy rp1 Artifacts

Detect and safely migrate legacy rp1 project artifacts. This command changes files and Arcade database rows, so require explicit confirmation before the mutating step.

Detect

Run:

rp1 agent-tools rp1-root-dir

Read data.needsMigration, data.migrationHint, data.isWorktree, and data.projectRoot from the successful result. If data.isWorktree is true, tell the user that migration targets the main repository at data.projectRoot, and that the command must be run from there. Stop and ask the user to rerun the skill from that main repository before previewing or applying migration.

If the command fails because the legacy project is missing project_id, treat that error as recoverable evidence that migration is needed. Stop only for the no rp1 project, run rp1 init error. If detection succeeds with needsMigration: false, report that there is nothing to migrate and stop.

Preview and Confirm

Run:

rp1 migrate --dry-run

Present the output as a partial preview: dry-run reports planned steps but does not compute exact file-move counts or stanza diffs. Recommend stopping Arcade if it is running because migration changes database rows. Ask for explicit confirmation before continuing.

Migrate and Verify

After confirmation, run rp1 migrate and show its summary. Then rerun rp1 agent-tools rp1-root-dir.

If needsMigration is false, confirm migration succeeded.
If it remains true, report the remaining reasons from migrationHint verbatim. Skipped conflicts or unrelated entries in the legacy directory are left in place by design; point the user to the legacy path and do not rerun migration in a loop.

Do not offer --to-central; it is out of scope for this skill. Refer users to the rp1 migrate reference documentation for that separate option.

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.
