The aw-compat agent has filed a codemod proposal (#27311) and a prior duplicate (#26812, closed) for automating the migration of legacy tools: {name: ...} entries to the new mcp-servers: block syntax. This is a recurring cause of compat failures (currently contributing to tools.serena failures in today's 4/20 failing repos, #27310). The migration is mechanical and fully automatable.
The codemod should: (1) parse each workflow's YAML tools: section, (2) identify entries whose name is not a built-in tool, (3) rewrite them as mcp-servers: entries with the appropriate schema, and (4) validate the output compiles cleanly.
Expected Impact: Eliminates the tools.serena class of compat failures. Can be run across all repos in the compat audit corpus in a single pass, reducing failing repos from 4 to ~2.
Suggested Agent: aw-compat agent or a general-purpose coding agent with YAML/Go skills
Estimated Effort: Medium (1–4 hours) — requires careful YAML transformation logic and validation.
