live-contract-compatibility
Skill9 starsChanged 4 months agoLicence not identifiedView on GitHub
Change a request/response shape, RPC contract, or message schema so that vN and vN+1 producers/consumers keep working while both are simultaneously alive — not just so a future reader can parse an old artifact. Use whenever changing a field, endpoint, protobuf message, or GraphQL type during or across a rolling deploy, or when clients (especially ones you cannot force to update, like a mobile app) may run an old contract indefinitely. Trigger on "breaking change", "rolling deploy", "mixed versions in prod", "add a required field", "rename a field", "remove an endpoint", "protobuf field number", "API version". Sibling of versioned-schema-evolution — that skill asks whether a new reader can interpret an old persisted artifact; this one asks whether two live versions of a contract can coexist while both are actually running.

The file
We split this skill into the rules it gives an agent
5 rules. About 0 are common, 3 are distinctive, and 2 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈3
Distinctive · estimate
This author's own choices. Worth a look.
2
Very specific
Tied to their project's names, files or tools. Probably skip.
The licence could not be identified — read it at the source. We count its rules but don't quote them. Read them on GitHub.
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
