Migration Diary: Port the Tool Contract Before a Free Server Inherits Paid Endpoints
You should port the tool contract before you repoint a coding workflow at free model access. Leftover paid endpoints, unbounded retries, and vendor tool names survive cancellation and keep steering the next run. A portable contract plus a leftover scan gives you a cutover you can rehearse on a laptop. Free server capacity does not repair a tool schema that still calls the old paid host. This…
The source material outlines a migration process for tool contracts when switching from a paid server to a free server. Key points include:
1. Port the tool contract before switching to a free server access, as leftover paid endpoints, retries and vendor tool names can persist even after cancellation.
2. Create a portable contract and leftover scan to rehearse the cutover on a local machine. Free server capacity alone will not fix any lingering schema issues calling the old paid host.
3. Review migration rules and drop bindings that only exist due to vendor SDKs hiding endpoints. Focus only on the rules that truly need to be migrated.
4. A paid coding agent stores three key components that survive a cancellation: the tool map (tool name, URL, timeout, retry policy), permission note (repos, shells, network hosts), and cache of failed calls (old host string and account ID).
5. When moving to a new host, separate portable behavior (file patterns, forbidden commands, diff size) from vendor residue (base URLs, proprietary tool names, telemetry flags, excessive retries).
6. Use a decision table to classify each binding as Keep (describes your repo), Rewrite (save but endpoint/tool/name changed), Drop (only satisfied a paid feature), or Block (could access secrets/production). Only migrate Keep rows after explicit human review.
7. Freeze a portable tool contract by creating a separate directory holding only the contract fields (tool name, paths, timeout, attempts). The residue file should contain any leftover vendor URLs, account IDs or vendor tool aliases that need to be removed.
8. After freezing, run a scanner script to classify each binding. Keep rows can be migrated without issue, Rewrite rows need new names/timeouts, Drop rows should not be redirected to a free model, and Block rows require human review before proceeding.
In summary, the source provides a detailed, step-by-step process for migrating tool contracts from a paid to free server environment while avoiding vendor residue and ensuring only necessary changes are migrated. The key is separating portable behavior from vendor-specific components and handling each binding appropriately through a classification decision table before proceeding with the migration.
